To all whom it may concern:

Be it known that we, JAMES M. BURDICK and CHRISTIAN BODMER, citizens of the United States, residing at New Britain, Hartford county, State of Connecticut, respectively, have invented certain new and useful Improvements in Planes, of which the following is a full, clear, and exact description.

This invention relates to an improvement in the construction of planes, and is more particularly concerned with the construction of a detachable cap piece for the cutter or “plane iron”. In such cap pieces, it has hitherto been the practice to provide a detachable cap piece provided with means for engaging with the cutter and clamping it in position upon its seat upon the plane body.

Our invention contemplates employing such a cap piece and utilizing one of the parts thereof as a palm rest. More specifically, the invention contemplates the employement of a base plate adapted to be seated over the cutter and a relatively movable palm rest portion, the cutter clamping means being carried by said cap piece and placed in clamping position by the movement of the palm rest relative to the base plate when the cap is seated on the plane over the cutter. In such a construction the locking parts are housed within the palm rest portion of the cap and thereby protected against accidental displacement. Furthermore, the cap is locked against loosening movement on the plane after the parts have once been moved to clamping position. Such a construction is shown and broadly claimed in our co-pending application Serial No. 708,733.

Our present invention comprises a new specific embodiment of the broad combinations of structure contained in said co-pending application and comprises more especially the specific combinations of parts recited in detail in the following specification and illustrated in the accompanying drawings.

In the drawings: Figure 1 is a longitudinal sectional view through a standard type of plane equipped with a detachable cap constructed in accordance with the present invention. Fig. 2 is a longitudinal section through a modified form of cap detached from the plane body.

Referring to the drawings by numerals: 1 designates the body of a plane provided with side walls or flanges 2 and a detachable shoe 3 at the forward end thereof, a throat 1a being formed at the forward end of the plane and in the rear of the detachable shoe portion thereof. 4 designates a frog or seat for the forward end of the “plane iron” or cutter, and 5 an interiorly threaded boss projecting upwardly from the plane body and carrying what is commonly termed a “cap screw” 6 provided with the usual headed end 6a. An adjusting lever 10 has its forward end seated over the boss 5 and is provided with an adjusting head 10a. To the rear of said head is a second adjusting device comprising a lever member 8 plvotally mounted at its forward end in the plane body and engaged at its rear end by an adjusting nut 9. A “plane iron” or cutter 7 is seated on the body of the plane with its forward end resting upon the frog or seat A and its cutting edge projecting into the throat 1a, the intermediate portions of the cutter resting respectively over the forward ends of the adjusting lever 10 and of the second adjusting lever 8. This cutter is provided with the usual longitudinal slot 7a through which the cap screw 6 projects and through and within which the adjusting head 10a extends, and with a plurality of corrugations 7b formed in its under face which are engaged by the forward end of the adjusting lever 8 to effect vertical adjustment of the cutting edge of the cutter. The lever 10, through its adjusting head 10a, effects lateral or angular adjustment of said cutting edge.

The parts so far described are merely those of a standard type of plane which has been selected for the illustrative application of the detachable cap embodying our invention. This cap embodies a base plate 11 having its forward end beveled and adapted for engagement with the forward end of the cutter 7, and is provided with the side walls or flanges 12. A pivot pin 13 extends transversely of the base plate 11 through the side walls 12 thereof, and has pivotally mounted upon its ends the forward ends of a palm rest section 14 the rear portion of which is formed as a hollow convex body serving as a palm rest. The body of the base plate adjacent the location of the forward end of the palm rest section is provided with a key-hole slot 15, and rearwardly thereof and adjacent the end of the base plate, with a second slot 16 through which extends the lower end of a lever member 17 pivotally carried by said base plate by means of the pivot pin 18 extending transversely of the base plate between the side walls 12 thereof. The lower edge of this lever is formed as a cam 19 and its upper end is formed with a curved oifset provided with a curved slot 20 therein. Projecting downwardly from the interior face of the palm rest 14 is an arm or bracket 21 provided with a pin 22 fitting within the curved slot 20 and designed, when the palm rest section is moved relative to the base plate, to cooperate with said slot and the upper end of said lever to move the lower cam end of the lever toward and away from the upper face of the cutter 7, or, when a clamping plate is employed in connection with said cutter, toward and away from said clamping plate. The forward end of the palm rest section of the cap in alinement with the forward edge of the keyhole slot 15 of the base plate, is provided with an aperture 23 designed to lit over the head 6a of the cap screw when the palm rest is moved downwardly, the sides of the palm rest adjacent said aperture forming an annular shoulder engaging the abutment formed by the head of said cap screw.

In Fig. 2, the cap shown therein is provided with the base plate 11, side walls or flanges 12, pivot pin 13, palm rest 14 pivotally carried thereby, keyhole slot 15, a second slot 16 to the rear of said keyhole slot and adjacent the rear of the base plate, and with an aperture 23 in alinement with the forward edge of the keyhole slot, these parts being the same as those shown and described in connection with Fig. 1. The lever member 17a, however, which is pivotally mounted in the base plate by means of the pivot pin 18a and has its lower end formed as a cam 19a is provided with a rearwardly extending offset instead of the forwardly extending curved offset shown in Fig. 1. This rearwardly extending offset is provided with a curved slot 20a and an arm or bracket 21a extending downwardly from the inner face of the palm rest section 14 and carries a pin 22a engaging in and cooperating with the curved slot 20a and the upper end of the lever member 17a’ to move the lower cam end 19a of the lever into and out of clamping engagement with the face of the cutter 7.

The application and operation of both forms of cap is substantially the same, and is as follows: Assuming that the cutter 7 is seated on the plane body and its parts, as is shown in Fig. 1, the detachable cap is seated over said cutter by bringing the enlarged end of the keyhole slot 15 in its base plate 11 over the head of the cap screw 6 and then moving the base plate and its attached palm rest section upwardly on the cutter to bring the narrow portion of the keyhole slot under the head 6a of the cap screw. When this is being done, the palm rest section of the cap is in raised position, as indicated in dotted lines in Fig. 1 of the drawings. After the base plate has been engaged with the cutter and cap screw 6, as described, the palm rest section is swung downwardly relatively to the base plate, this movement, through pins 22–22a, swinging the lower cam edges 19–19a of the clamping levers into frictional clamping engagement with the upper face of the cutter 7 so that by the time the pins 22–22a reach the lower ends of slots 20–20a to stop the further relative movement between the palm rest and base plate, the cam ends 19–19a will have frictionally engaged and securely clamped the cutter 7 in position on the plane body. This clamping engagement is such that it holds the cutter so tightly on its seat that under ordinary service conditions, its position relative to the plane body will remain unchanged. The cutter, however, is always capable of being adjusted without in any way loosening the cap.

Owing to the engagement of the keyhole slot 15 with the cap screw 6, there is a possibility that during service the cap might be loosened and slide longitudinally of the cutter 7 despite the fact that its bottom plate is held to said cutter by the frictional engagement therewith of its clamping lever. The provision of the apertures 23 in the forward end of the palm rest section is designed to prevent any possibility of such movement, and when the palm rest is moved downwardly to actuate the clamping lever to frictional clamping engagement with the cutter, the head 6a of the cap screw projects through this aperture 23, the edges of the palm rest section adjacent said aperture forming annular shoulders engaging the abutment formed by the head of the cap screw and preventing movement of the cap relative to the plane body.

To detach the cap from the plane, it is only necessary to move the palm rest upwardly from the base plate, the application of sufiicient force causing the pin 22 or 22a to move in the curved slot of the clamping lever member and by frictional pressure, move the lower cam end of the lever out of clamping engagement with the cutter 7. When the palm rest has thus been moved upwardly and the cam end of the lever retracted from engagement with the cutter, the forward apertured end of this palm rest section will have been moved from locking engagement with the head of the cap screw, and the base plate 11 may now be moved downwardly on the cutter 7 to bring the enlarged end of the keyhole slot in line with the cap screw 6, whereupon the base plate and its attached palm rest may be removed from the cutter and plane body.

The structure of the cap and its connections is susceptible of modification within the spirit of our invention and the scope of the appended claims.

What we claim, therefore, and desire to secure by Letters Patent is:

1. In a plane, in combination, a body provided with a cutter seat, a cutter positioned thereon, an abutment carried by said body and a detachable cap comprising a base adapted to be seated over said cutter and engage the forward end thereof and also adapted to engage said abutment, and a palm rest pivotally connected adjacent one end to said base between its ends, a separately formed cam lever being pivotally carried by one of said parts in rear of the pivoted end of the palm rest and having a curved slot therein, and a pin being carried by the other of said parts and being seated in said curved slot whereby the movement of said palm rest relative to its base actuates said cam lever to clamp said cutter on its seat.

2. In a plane, in combination, a body provided with a cutter seat, a cutter positioned thereon, an abutment carried by said body and a detachable cap comprising a base adapted to be seated over said cutter and engage the forward end thereof and also adapted to engage said abutment, and a palm rest pivotally connected adjacent one end to said base between its ends, a separately formed cam lever being pivotally carried by one of said parts in rear of the pivoted end of the palm rest and having a curved slot therein, and a pin being carried by the other of said parts and being seated in said curved slot whereby the movement of said palm rest relative to its base actuates said cam lever to clamp said cutter on its seat, the end of said palm rest being provided with a shoulder adapted to engage said abutment upon such movement to thereby lock the cap against movement relative to the abutment and its plane body.

To all whom it may concern:

Be it known that we, CHRISTIAN BODMER and JAMES M. BURDICK, citizens of the United States, residing at New Britain, Hartford county, State of Connecticut, have invented certain new and useful Improvements in Planes, of which the following is a full, clear, and exact description.

This invention relates to planes and particularly to an improved form of “plane iron” or cutter cap.

In planes heretofore it has been customary to provide the cutters or “plane irons” with a detachable cap piece adapted to be seated thereover and provided with means for clamping the cutter in its adjusted position on its seat.

Our invention contemplates forming such a detachable cap with a plurality of relatively movable parts, one of which constitutes a palm rest, the cap being provided with means cooperating in one position of the parts to clamp the cutter in position on its seat against accidental displacement and to hold the cap against movement when in such locking position. The clamping of the cutter on its seat is such that it may be adjusted through suitable means without disturbing the position of the cap parts which will act to hold the cutter in its new position against accidental displacement.

In the specific embodiment of the invention selected for illustration, the parts easily susceptible of accidental actuation are housed within the palm rest when the cap is seated over the cutter in clamping position, and are thereby protected against accidental actuation to destroy the adjustment. In addition the positioning of the parts of the cap over the cutter to hold the same upon its seat against accidental displacement serves to retain the cap on the cutter against displacement relative thereto and to the plane, although, of course, adjustment of the cutter itself is possible as already stated. These and other advantages will be seen from the more detailed description following and from the accompanying drawings in which:

Figure 1 is a longitudinal section through a standard type of plane equipped with one form of detachable cutter cap constructed in accordance with our invention. Fig. 2 is a bottom plan view of the cap shown in Fig. 1, detached from the plane. Fig. 3 is a longitudinal section through a detachable cap of slightly modified form with the parts thereof in locking position and the cooperating parts of the plane omitted, the palm rest being shown in dotted lines in raised unlocked position. Fig. 4 is a partial end view of the cap shown in Fig. 3, the palm rest being raised. Fig. 5 is a bottom plan view of the cap shown in Figs. 3 and 4. Fig. 6 is a longitudinal sectional view of another modified form of cap. Fig. 7 is a fragmentary plan view of a cap illustrating a modified form of locking abutment shoulder.

Referring to the drawings by numerals: 1 indicates the body of a plane of conventional design and 2 the side flanges or walls thereof. 3 denotes a detachable shoe carried by the forward end of the plane body, a throat 1a being formed in the body adjacent and to the rear of said shoe.

4 indicates a frog or se-at for the end of the cutter and 5 an interiorly apertured and threaded boss projecting upwardly from the body of the plane intermediate its ends and to the rear of the frog or seat 4. Screwed into the threaded aperture of and extending from the boss 5, is what is commonly termed a “cap screw” 6 forming an abutment for the cap. A plane iron or cutter 7 provided with the usual longitudinal slot 7a and corrugations 7b on its under face, is seated on the plane body with its forward end resting upon the frog 4 and its cutting edge extending into and through the throat 1a. The corrugated under face of the cutter 7 rests upon and is engaged by the toothed end of a pivoted adjusting lever 8 having a cooperating actuator member 9 and designed to be operated to effect vertical adjustment of the cutting edge of the cutter 7 in the usual manner. An adjusting lever 10 is mounted upon the boss 5 and carries an adjusting head 10a which fits through the longitudinal slot forming the cutter, and is adapted to be moved through the lever 10 to effect angular adjustment of the cutting edge of the cutter 7. The cutter itself rests on the plane body with its forward edge supported on the frog or seat 4 and its intermediate portions seated over the ends of adjusting levers 10 and 8. The cap screw 6 extends up through the longitudinal slot 7a formed in the cutter and is provided with the usual shouldered head 6a.

The parts so far described are merely those of a standard type of plane selected as a type appropriate for use with the detachable cap embodying our invention. This cap is preferably formed of either cast iron or steel, or of a combination of both. In Figs. 1 and 2 of the drawings we have shown a cap as formed of cast iron and in Figs. 3, 4, 5 and 6 the cap shown therein illustrates the article as made from steel. Referring more specifically to the construction shown in Figs. 1 and 2, this cap embodies a base plate 11 having a beveled forward edge 11a and side walls 12 extending around the edges of the plate from its forward end. A slot 13 is formed in and extends longitudinally of the base plate from its rear end and terminates at its outer end in a key-hole slotted portion 14. Intermediate of its ends, base plate 11 is formed with bearings 15 projecting inwardly from the side walls 12 and serving as journals for pivot pins 16 on which are pivotally mounted the forward end portions 17 of a hollow convexed body 18 forming a palm rest. A lever 19 extends within the slot 13 adjacent its rear end and is pivotally mounted upon the base plate by means of the pivot pin 20 extending transversely of the base at such point and mounted in the side walls 12 thereof. The lower edge of this lever 19 is formed as a cam 21 and its upper end is shouldered at 22 and a link 23 pivoted thereto at 24. The other end of this link is pivotally carried at 26 by a bearing bracket 25 extending from the under face of the palm rest 18. This palm rest at its forward end and in alinement with the forward or narrow end of the key-hole slot 14, is provided with an aperture 27 designed to fit over the head 6a of the cap screw, the edges of the palm rest adjacent said aperture forming an annular shoulder engaging the abutment formed by the head of said cap screw.

In the operation of the cap thus described, the cutter 7 being seated in proper position on the plane body with its cutting edge suitably adjusted, the base plate is seated over the head of the cap screw 6 with the enlarged portion of the key-hole slot over the head of the screw 6 and is moved upwardly to bring the narrowed portion of the key-hole slot 15 under the head of the cap screw 6. The palm rest 18 (which, when the cap is being mounted on the plane, is in raised position such as indicated in dotted lines in Fig. 1), is now moved downwardly toward the cutter 7 and base plate 11. This movement of the palm rest will, through the connecting link 23, move the lower cam edge 21 of the lever 19 forwardly and into frictional contact with the upper face of cutter 7 (or when a clamping plate is employed in conjunction therewith, into contact with said clamping plate). This action of the cam 21 will cause the cutter to be clamped upon its seat against accidental adjustment destroying movement. The clamping action is such that the cutter is held on its seat with enough force to maintain such position thereon during ordinary use, but as before stated, it can always be adjusted when so held without loosening the cap. The parts are so constructed that during such positioning of the palm rest 18 to effect this clamping action the pivot. 26 will be brought below the “dead center” line between pivots 24 and 16 thereby frictionally locking the parts in such cutter clamping position, the upper end of the link 23 abutting against the under face of the palm rest 18 and preventing further downward movement.

Owing to the engagement of the key-hole slot 14 with the cap screw 6, there is some possibility of the cap loosening and drawing back during use. To prevent such action the palm rest 18 when the parts are moved to clamp the cutter on its seat, moves its aperture 27 over the head 6a of the cap screw so that the sides of the palm rest adjacent said aperture form an annular locking shoulder engaging the abutment formed by the head of said cap screw. As this cap screw is fixed relative to the body of the plane it is evident that movement of the cap relative to said body is impossible.

In the form of the cap shown in Figs. 3, 4 and 5 of the drawings, the cap comprises a base plate 28 having its forward edge shaped for engagement. with the forward edge of the cutter and provided with tianges or side walls 29. A pivot. pin 30 extends transversely of the body of the base plate and between its side walls 29 and serves to pivot on said body the forward ends of a hollow convened body 32 forming a palm rest. The body of the base plate 28 at a point adjacent the said end of the palm rest 32 is provided with a key-hole slot 31 and adjacent its rear end and between its side walls 29 is provided with a second slot 33 through which extends the lower end of a lever 34 pivotally mounted adjacent its lower edge by pivot pin 35 carried by the side walls 29 and extending transversely of the base plate. The lower edge of this lever 34 is formed with a cam 36 and at its upper end, the lever is shouldered at 37. Complemental links 38 are pivotally secured to the upper end of lever 34 by means of the pivot pin 39. These links at their other ends are secured to a bearing bracket 40 carried by the palm rest 32, a pivot pin 41 serving to pivotally attach the forward ends of these links to said bearing bracket. The front end of the palm rest 32 in line with the forward or neck portion of the key-hole slot 31, is provided with an aperture 42 designed, when the palm rest is moved from the position indicated in dotted lines in Fig. 3 to that shown in full lines, to rest over the head 6a of the cap screw 6 of the plane. The action and operation of this form of cap is the same as that of the form shown in Figs. 1 and 2, the two forms differing in detail of construction only.

In Fig. 6 we have shown a further and more radical modification. In the two forms heretofore described, the link connections between the cam lever and the palm rest are locked against accidental retraction when the cap is seated on the plane in cutter clamping position, this being effected in part by the fact that the pivots 26 and 41 of these two respective forms are moved beyond “dead center” when the cap is moved to cutter clamping position. In the present modification, the base plate 43 is provided with side flanges or walls 44, a key-hole slot 45 and a second and rearward slot 46 through which a lever 49 projects, a pivot pin 50 serving to pivotally connect the lower end of the lever to the side walls 44 of the base plate and the parts so far described corresponding substantially to those shown and described in Figs. 3 and 4. At its lower edge the lever 49 is provided with a cam 51 and is shouldered adjacent its upper end at 52, and a link 54 pivotally connected to said upper end by the pivot pin 53. The hollow convened palm rest 48 is pivotally connected to the base plate 43 by means of the pivot pin 47 extending transversely thereof and through the forward ends of its side walls 44. From its interior face and intermediate its ends, a bearing bracket 56 extends and the other and forward end of the link 54 is pivotally connected to this bearing bracket by means of the pivot pin 55. Adjacent its forward end and in line with the forward end of the key-hole slot 45, a palm rest is provided with the locking aperture 57 corresponding in location and action with those shown in the other figures of the drawing. In the use of this modified form of cap, when the base 43 has been seated on the plane body in the usual manner and moved to bring the narrow portion of its key-hole slot 45 under the head of the cap screw 6, the palm rest 48 is moved downwardly relatively to the base plate 43; this movement, through the connecting link 54, swings the lower end of the lever 49 forwardly to bring its cam end 51 into frictional clamping engagement with the upper face of the cutter, further downward movement on the part of the palm rest being prevented by the engagement of the forward end of the link 54 with the upper face of the body of the base plate 43. When the parts are so moved, the aperture 57 in the forward end of the palm rest, will be seated over the head of the cap screw thereby locking the cap against movement relative to said screw. The frictional engagement of the cam end 51 of lever 49 retains said lever and its actuating link in locking position.

In the forms previously described, the cap has been locked against loosening movement by the fact that apertures formed adjacent the forward end of the palm rest section. of the cap have been seated over the head of the cap screw, the sides of the palm rest section adjacent such apertures forming annular locking shoulders. In Fig. 7 we have shown a modification of this locking feature wherein the locking aperture is omitted and a single lip or locking shoulder provided. Referring specifically to Fig. 7, 58 indicates the base plate of a detachable cap and 59 the palm rest section thereof pivotally connected thereto at 60. 61 indicates the forward end of a key-hole slot formed in the base plate, the position of the head of the “cap screw” being indicated in dotted lines at 62. The forward edge of the palm rest section is provided with a central lip or shoulder 63 which, when the cap is seated in cutter clamping position will move down over and abut against the edge of the screw head and lock the cap against displacement relative thereto during service.

In order to detach a cap from the plane, it is only necessary to move the palm rest upwardly from the base-plate, the application of sufiicient pressure thereagainst serving through the connecting links to move the lower cam end of the lever from frictional clamping engagement with the cutter 7. When the palm rest has been thus moved upwardly, the forward apertured or shouldered end of the palm rest section will have been moved out of locking engagement with the head of the cap screw and the base plate may now be moved to bring the enlarged end of its key-hole slot in line with the cap screw 6, whereupon the base plate and its attached palm rest may be removed from the cutter and plane body.

While we have herein described and illustrated specific embodiments of our invention, various modifications thereof are possible within the spirit of the invention and of the appended claims.

What we claim is:

To all whom it may concern:

Be it known that I, JAMES M. BURDICK, a citizen of the United States, residing at New Britain, Hartford county, State of Connecticut, have invented certain new and useful Irnprovements in Planes, of winch the following is a full, clear, and exact description.

This invention relates to an improvement in the construction of planes, and is more particularly concerned with the construction of a detachable cap piece for the cutter or “plane iron”. In such cap pieces, it has hitherto been the practice to provide a detachable cap piece provided with means for engaging with the cutter and clamping it in position upon its seat upon the plane body.

My present invention contemplates employing such a cap piece in the form of a main body portion provided with a palm rest and carrying a relatively movable clamping member adapted to be positioned to engage and clamp the cutter on its seat and to lock said cap piece against movement relative to the plane body.

In the drawings illustrating a preferable embodiment of the invention: Figure 1 is a longitudinal section through a standard type of plane equipped with a detachable cap constructed in accordance with the present invention. Fig. 2 is a top plan view of said cap removed from the plane body.

Referring to the drawing by numerals: 1 designates the body of a plane provided with side walls or fianges 2 and a detachable shoe 3 at the forward end thereof, a throat 1a being formed at the forward end of the plane and in the rear of the detachable shoe portion thereof. 4 designates a frog or seat for the forward end of the “plane iron” or cutter, and 5 an interiorly threaded boss projecting upwardly from the plane body and carrying what is commonly termed a “cap screw” 6 provided with the usual headed end 6a. An adjusting lever 10 has its forward end seated over the boss 5 and is provided with an adjusting head 10a. To the rear of said head is a second adjusting device comprising a lever member 8 pivotally mounted at its forward end in the plane body and engaged at its rear end by an adjusting nut 9. A “plane iron” or cutter 7 is seated on the body of the plane with its forward end resting upon the frog or seat 4 and its cutting edge projecting into the throat 1a, the intermediate portions of the cutter resting respectively over the forward ends of the adjusting lever 10 and of the second adjusting lever 8. This cutter is provided with the usual longitudinal slot through which the cap screw 6 projects and through and within which the adjusting head 10a extends, and with a plurality of corrugations 7b formed in its under face which are engaged by the forward end of the adjusting lever 8 to effect vertical adjustment of the cutting edge of the cutter. The lever 10, through its adjusting head 10a, effects lateral or angular adjustment of said cutting edge.

The parts so far described are merely those of a standard type of plane which has been selected for the illustrative application of the detachable cap embodying the invention. This cap is formed as a main body portion comprising a base portion 11 adapted to be seated over the cutter and having side walls or flanges 12 extending longitudinally thereof and beyond the end of the base portion 11, said flanges being widened and joined to form the rounded hollow palm rest 13. The base portion 11, at its rear end, is formed with a slot 11a and with spaced ears 14 extending upwardly from said base portion at the rear end thereof and positioned on either side of said slot. Intermediate its ends, and forward of the ears 14, the base portion 11 is provided with a key-hole slot 15. A clamping lever 16 is pivotally mounted adjacent its rear end between the ears 14, said end extending downwardly between the ears 14 and through the slotted portion 11a and being formed at its extremity as a cam 18. This lever 16 extends forwardly to a point adjacent the key-hole slot 15 and is provided at its forward end with an upwardly extending handle or finger piece 19 and adjacent said handle, with a locking shoulder 20 extending downwardly therefrom. This shoulder is posi-
tioned to lie in substantial alinement with the rear end of the narrowed portion of the key-hole slot 15. The main body portion, with its ears 14, side walls 12 and rearward extension 13 forming the palm rest, may be, and preferably is, formed as an integral structure.

With the foregoing construction of the parts in mind, the application and operation of the cap is as follows: Assuming that the cutter 7 is seated on the plane body as shown in Fig. 1 with the cap screw 6 extending up through its slotted portion 7a, the detachable cap is seated over the cutter by bringing the enlarged end of the key-hole slot 15 in its base over the head of the cap screw 6 and then moving the body portion upwardly to bring the narrowed portion of the slot under the head 6a of the cap-screw. When this has been done, the operator grasps the handle 19 of the clamping lever and moves it downwardly to bring the cam 18 into frictional clamping engagement with the upper face of the cutter 7 (or, when a clamping plate is employed in conjunction with the cutter, with the upper face of said clamping plate). When the cam has been thus moved to clamping engagement with the cutter, the locking shoulder 20 will have been moved over the head 6a of the cap screw and will abut and be locked thereagainst by reason of the frictional engagement of the cam 18 with the cutter 7. From this, it will be evident that the cutter is firmly held on its seat and that the cap cannot be accidentally moved longitudinally of the plane body to break the clamping engagement of the cam 18 therewith. The frictional clamping engagement of the cam with the cutter is such that it is sufficient to retain the cutter fixed on the seat under ordinary conditions of service, but permits adjustment of the cutter by suitable means without disturbing or loosening the cap.

While I have shown and described a specific embodiment of a detachable cap, various modifications and changes in structure thereof are possible within the spirit of the invention and the scope of the appended claims.

What I claim, therefore, and desire to secure by Letters Patent, is:

1. In a plane, in combination, a plane body provided with a cutter seat, a cutter positioned thereon, an abutment carried by said plane body, and a detachable cap for said cutter comprising a main body portion adapted to be seated over said cutter and a palm rest connected to said main body portion and a relatively movable member carried by said body portion and adapted to be positioned to engage and clamp said cutter on its seat and to engage said abutment and lock said body portion against movement relative thereto and to said plane body.

2. In a plane, in combination, a plane body provided with a cutter seat, a cutter positioned thereon, an abutment carried by said body portion, and a detachable cap for said cutter comprising a base adapted to be seated over said cutter to engage said abutment and a paim rest extending rearwardly of said base, and a clamping lever pivotally carried by said cap and formed for simultaneous engagement with said abutment and said cutter whereby said lever may be actuated to engage and clamp said cutter on its seat and also to simultaneously engage said abutment and lock said body portion against movement relative to said plane body.

3. In combination with a plane body provided with a cutter seat and with an upwardly projecting abutment, a detachable cutter cap comprising an integral body portion embodying a base adapted to be seated over the plane cutter and to engage said abutment, and a portion extended rearwardly of said base to form a palm rest, and a lever pivoted adjacent one end to said rearwardly extending portion and having said pivoted end provided with a cutter-clamping cam and having its outer end formed with a locking shoulder adapted to engage said plane abutment when said lever is moved to cutter clamping position, thereby locking said body portion against movement relative to said abutment and to said plane body.

To all whom it may concern:

Be it known that I, ALBERT A. PAGE, a citizen of the United States, residing in the city and county of New Haven, State of Connecticut, have invented new and useful Improvements in Tongue-and-Groove Planes, of which the following is a full, clear, and exact description when taken in connection with the accompanying drawings.

My invention relates to reversible or invertible tongue and groove planes, and the primary object of the invention is to provide a tool of this sort which is practically as handy and convenient in use as the well known tongue cutting planes and grooving planes in which the tongue cutting function and the groove cutting function are not combined.

It is also aimed to produce a plane of this kind which is not only handy and well balanced but also of comparatively light, simple and inexpensive construction. The main advantage of the improved tool resides, however, in the fact that it provides a very convenient and satisfactory grip for the workman, whether used for tongue cutting or grooving, and that it is peculiarly compact, and has the respective cutters so arranged as to do the most effective work.

In these drawings, Figure 1 is a side elevation of the plane; Fig. 2, a plan view of the edge adapted to fit the groove; Fig. 3, a plan view of the edge adapted to form and engage the tongue; and Fig. 4, a cross section on the line x–x of Fig. 1.

In all figures, similar letters of reference represent like parts.

Referring to the drawing, the open skeleton frame constituting the stock is shown at 1. This frame comprises parallel lower and upper edge portions 4, 5, of which the former acts as a bearing surface when cutting the tongue, while the latter serves as a bearing surface in cutting the groove. These parallel bearing portions of the skeleton frame are connected at the ends of the plane, preferably in an integral manner, by handle or grip portions 2, 3, respectively. These handle or grip portions, while slightly curved in a longitudinal direction and of appropriate cross-section, in order to form a convenient and satisfactory grip for the hand of the workman, are generally parallel with respect to each other and form, in connection with the parallel bearing portions, 4, 5, a stock of substantially rhomboidal shape.

Projecting inwardly from the respective bearing portions 4, 5, are lugs or brackets 13 and 15 respectively against which the respective bits 8 and 14: are positioned. The supporting brackets or lugs 13 and 15 are preferably formed integrally with the bearing portions 4 and 5 and are equipped with flat bearing surfaces for the bits, which bearing surfaces are directed parallel to each other and substantially parallel with one of the diagonals of the rhomboidal figure formed by the intermediate open space between the handles 2 and 3. By placing the supporting brackets and the bits in superposed relation, as shown, with one bracket and its bit placed oppositely with respect to the other bracket and bit as regards the diagonal aforesaid, it is possible to shorten the plane materially while still providing for the location of the cutting edges of the respective bits at the proper distances from the respective ends of the plane. In other words, by this construction I am enabled to provide an efficient plane of minimum length wherein the distance from each cutter to one end of the plane bears such a ratio to the distance from said cutter to the other end of the plane that the bearing portions 4, 5, coact properly and effectively with the respective bits.

The bearing portion 4 is provided at one side with a relatively short depending flange 6 creating a groove 7 into which projects the tongue cutting bit 8, the cutting end of which is recessed at 9 in order to form the tongue in well known manner. The bit 8 is positioned relatively to its support 13 by means of a lever pivoted at 12 and bearing against the bit at one end, while the opposite end carries a clamping screw 10 coacting with the bit in well known manner. The bearing portion 5 is provided with a groove 20 and with a flange 19 alined with the cutting edge 21 of the bit or cutter 14. This bit or cutter is positioned relatively to its support 15 by means of a lever 16 pivoted at 17 and having a clamping screw 18.

The operation of the device is as follows: When it is employed for forming and planing the tongue in the edge of the work, the latter is engaged with the groove 7 and the grip member 2 engaged by the hand of the operator. In the operation of the device in this position the slot 9 will leave a central unplaned space on the edge of the board of the desired width of the tongue and in the continued movement of the plane the portions on either side of this space will be planed down so as to form a tongue of the proper width. After the tongue has been formed it is merely necessary to reverse the plane edge for edge and grasp the grip member 3 by the hand and apply the rib 19 to the opposite edge of the board or edge of another board, and then operate the plane for the purpose of forming the groove, the cutter 21 engaging said edge and forming the groove.

By forming the plane of substantially rhomboidal shape a most satisfactory grip may be afforded by the handles 2 and 3. By locating the bits and bit supports in the manner described the construction of the tool is simplified and its expense lowered, and in addition to this, the tool is made light and well balanced, and is especially effective in operation.

Having thus described my invention, what I claim and desire to secure by Letters Patent, is :–

l. An invertible or reversible tongue and groove plane comprising parallel oppositely located bearing portions, handle members joining the respective ends of the respective bearing portions and forming in conjunction with said bearing portions a skeleton frame or stock of substantially rhomboidal form, separate bit supports projecting from the respective bearing portions into the inner open portion of the frame or stock, said bit supports being arranged in superposed relation and having bearing surfaces directed substantially parallel to one of the diagonals of the rhomboidal opening of the frame or stock, and bits clamped on the respective bearing surfaces and cooperating with the respective bearing portions; substantially as described.

2. An invertible or reversible tongue and groove plane comprising parallel oppositely located bearing portions, handle members joining the respective ends of said bearing portions and forming in conjunction therewith a skeleton frame or stock of approximately rhomboidal form, bit supports formed integrally with the respective bearing portions and extending therefrom into the inner open portion of the frame or stock, and bits clamped on the respective bit supports, substantially as described.

3. ln an invertible or reversible tongue and groove plane, an open skeleton frame formed of oppositely arranged parallel bear-
ing portions and handle members connecting the respective bearing portions at the ends of the plane, approximately parallel bit supports extending inward from the respective bearing portions into the inner opening of the frame, said bit supports being arranged in superposed relation and having their bit supporting surfaces opposing or facing each other, and bits clamped on said surfaces and cooperating with the respective bearing portions, substantially as described.

ln witness whereof, I have hereunto set my hand on the 21st day of September, 1911.

To all whom it may concern:

Be it known that I, EDMUND A. SCHADE, a citizen of the United States, residing at New Britain, county of Hartford, State of Connecticut, have invented certain new and useful lmprovements in Planes, of which the following is a full, clear, and exact description.

My invention relates to improvements in planes, and particularly to that type of plane in which the main body or stock is formed of wood.

My improvement aims at providing an improved construction for reinforcing the wood stock at the weakest point, namely, at the throat opening, where much of the wood is out away. Incidentally, but none the less important, the means for reinforcing the wood body cooperates in an improved manner with other new features of construction to hold the frog or cutter carrier seat securely in position.

ln the drawings Figure 1 is a plan view of a part of a plane, constructed to embody my invention, the frog and plane iron being removed, the ends of the main reinforcement being broken away. Fig. 2 is a section on the line x–x Fig. 1, showing the cutter carrier, or frog, in place. Fig. 3 is a relatively enlarged sectional view of a detail of construction, on the section y–y Fig. 1. Fig. 4 is a plan view of a modification of the same detail. Fig. 5 is a sectional view of the modified detail shown in Fig. 4. Fig. 6 is a sectional view of still another modification of the same detail.

1 represents the main body or stock of a plane, the same being of substantial length, breadth and thickness, and being formed of wood. At an intermediate point in the length of the main body the stock is cut away down to the throat passage 2 to form a space for the plane iron and for the clearance of shavings. This cut-away portion always tends, in planes of this character, to substantially weaken the stock 1. To reinforce and strengthen said stock 1, I apply to the top side thereof a metal bracing or reinforcing piece of peculiar design, including a relatively wide plate 3 terminating in relatively narrowed-in extensions 4–5.

6–7 are integral upright reinforcing ribs bordering the sides of the reinforcing plate and bridging the plane iron passage in said plate and also in said stock. These ribs 6–7 give great rigidity to the reinforcing plate, so that when the same is properly secured to the stock 1, the weakened part thereof, as before pointed out, will be adequately strengthened so as to prevent all danger of breakage.

The usual hand grips may be provided at each end of the plane, the forward grip being shown at 8, the rear grip being omitted for want of room on the drawings.

Both ends of the reinforcing plate are secured to the wood stock 1 by means of screws 9–10. It is obvious that unless the middle portion of the reinforcing plate 3 is adequately secured to the stock, that the latter will not be properly braced. Hence I have provided means which not only serve to secure the plate at a middle point, between the screw fastenings 9–10, to the wood stock, but also serve to effectively hold the frog in any of the adjusted positions without strain upon the reinforcing plate.

11 represents the cutter support or frog, which in general is of well known design, and hence needs no detailed description. 12 represents the base of said frog. In this base, at each side, are provided screw-slots or passages, one of which appears in the upper portion of Fig. 1. Directly under these passages, and securely anchored in the wood stock 1, are cylindrical anchor blocks 13–13 drilled and tapped to receive the clamping screws 14, one of which appears in Fig. 2. The screws 14 pass through longitudinal slots in the frog, and enter the anchor blocks 13. These anchor blocks 13–13 may be shaped on the outside in any desired way, so long as they may be securely embedded and retained in the wood stock 1 in a rigid manner. For example, in the drawings, Figs. 1 to 3, each block 13 is shown as having an external coarse thread, which permits said block to be screwed into the wood stock 1. When said block is screwed down firmly in place, it is held against turning preferably by a pin 15, which acts as a key. The outer side of each block may have one or more vertical grooves or key-ways to permit one side of said key pin 15 to project partly into said anchor block when the latter has been screwed home.

ln Figs. 4 and 5, I have shown a slight modification of the anchor block, in which the outer wall thereof is unthreaded and arranged to be forced directly into a bore in the stock 1. In this modiiication the block is indicated at 13a and is held in place by means of wood screws 16, the upper end of the block being cut away or notched to permit part of the screw-head of each screw 16 to enter the notch and hold the block down in place and at the same time prevent it from turning with the clamping screw 14.

In Fig. 6, I have shown another modification of the block, said block being indicated at 13b, the same being similar to the block 13a with the exception that the outer side is provided with a coarse thread. In this instance the block is held in place against vertical displacement by the screw-threads and against turning by screws 16–16, as in Fig. 5.

The effect of this combination of parts is as follows: When the reinforcing plate is applied to the base 1, it is held at its ends by the screws 9–10, and, while an additional screw or screws may be provided whenever desired, the same are unnecessary, in view of the fact that when the frog 11 is in place and is clamped down by the screws 14, the drag of said screws tends to hold not only the frog 11 tightly on the reinforcing plate 3, but also holds the reinforcing plate 3 rigidly down upon the stock 1. By this arrangement, a long screw-bearing is provided for the clamping screws 14, as would not be the case if the screws 14; relied alone upon threads cut in screw passages on the comparatively thin reinforcing plate 3, for in such a case there would be danger of stripping the threads. Not only is it important to secure a firm and effective anchorage for the clamping screws 14 for the purpose of holding the clamping plate 3 tightly to the stock 1, but it is also important for the purpose of holding the frog 11 tightly upon its seat so as to prevent all danger of chattering of the plane iron. It is clear that it is of the greatest advantage to secure the plate 3 to the wood stock 1 directly at, or as near as possible to, the point where the strain occurs. Since the anchor blocks 13–13 are arranged closely adjacent to the rear of the plane iron passage in the reinforcing plate, it is obvious that a maximum of resistance to strains is adorded at this point, whereby the frog, top iron and stock 1 are securely braced at a point close to the mouth or cutter passage.

From the foregoing it will be observed that the plane of stress of the clamping screw or screws is always within the zone of resistance against upward movement of the means for holding the anchoring device, and it is also apparent that the plane of stress of said clamping screws is in advance of the rear fulcrum of the frog, hence the frog cannot by any possibility yield and chatter by any upward pressure applied to the front portion of the frog, as when the plane is in use.

What I claim is:

In a plane of the character described, a wood stock having a cutter passage extending through the same from the top to the bottom at a point intermediate its ends, an anchoring means rigidly embedded in said stock close to the rear of said cutter passage, means for holding said anchoring means from movement in any direction in said stock, a frog mounted on said stock at the rear of said cutter passage, and a clamping screw passing through said frog and arranged to screw into said anchoring means, said frog having a longitudinally slotted passage for said clamping screw to permit adjustment fore and aft, the plane of stress of said clamping screw being with-
in the zone of resistance to upward movement of the anchor holding means and forward of the rear fulcrum of said frog.

To all whom it may concern:

Be it known that I, CHRISTIAN BODMER, a citizen of the United States, residing at New Britain, county of Hartford, State of Connecticut, have invented certain new and useful Improvements in Planes, of which the following is a full clear and exact description.

My invention relates to an improvement in planes, the object of the invention being to provide a simple and efficient plane construction which may be used for the purpose of accurately truing up or squaring up the edges of boards. Where heretofore various more or less complex constructions, including separate attachments, have been provided in conjunction with plane bodies for accomplishing this purpose, in the present invention the plane body itself is of unique construction, being integral throughout, the handle portion being so arranged that the pressure applied to the plane is in such a direction relatively to the work being done that said plane naturally seeks a true position upon the board being planed.

In the drawings Figure 1 is a plan view of the plane complete, ready for use and practically full size. Fig. 2 is a side elevation thereof. Fig. 3 is a front end elevation.

The frame is made of a single body casting and comprises two right-angle side fianges 1–2, which furnish the two right-angle bearing faces 1a–2a respectively. The flange 1 is continued upwardly at its front end to form an inclined and rearwardly facing thumb-rest 3. To the rear of the thumb-rest 3 and back of the middle line of the plane is a palm-rest 4 formed by a cross-web or flange set at an angle on the upper end of flange 1 and projecting above flange 2. This palm-rest is bulged to conform to the palm of the hand, so that the position of the hand upon the plane body will be such that pressure applied will cause both bearing surfaces 1a–2a to press uniformly upon the surface and edge of the board being planed. Upon the outer side of the plane is supported at a proper angle a cutter 5. The side flange 1 is provided with a throat, preferably oblique, in which throat the cutting edge of the plane iron or cutter 5 stands.

6 is a cap detachably held at the middle by the usual screw 7. 8 is a clamp screw at the rear of the cap, for causing said cap to properly engage the cutter to hold it tightly upon its support and in its properly adjusted position. The palm-rest 4 is preferably connected with the flange 2 by means of flanges or ribs 9–10, formed by widening the ends of the cross-web and which serve to rigidly hold the two flanges against distortion.

11 is a lug to support the cutter at its side edge to prevent it from turning during the progress of the work. The width of the cutter is such that it extends the full width of the bearing surface 1a.

12 is a reinforcing rib, which bridges the plane body at the end of the throat in which the cutter stands, so as to stiffen the same at this otherwise weakened point, due to forming the throat. The rib 12 is preferably extended around the forward end of the plane and also rearwardly back to the bulged palm support or bearing.

What I claim is :–

1. As an article of manufacture, a one-piece metal casting forming the body of a plane and comprising a work collocating tool guiding flange and a slotted tool carrying flange extending therefrom and forming a right angle, and an integral palm rest arranged at the rear end of said casting extending outwardly from and obliquely to the line of junction of said flanges and formed by a cross-web or fiange set at an angle on the upper edge of the tool carrying flange and which projects above the first mentioned flange.

2. As an article of manufacture, a one-piece metal casting forming the body of a plane and comprising a work collocating tool guiding flange and a slotted tool carrying flange extending therefrom and forming a right angle, and an integral palm rest arranged at the rear end of said casting extending outwardly from and obliquely to the line of junction of said flanges and formed by a cross-web or flange set at an angle on the upper edge of the tool carrying flange and which projects above the first mentioned flange, the ends of said web being widened to form flanges across the latter flange.

To all whom it may concern:

Be it known that we, CHRISTIAN BODMER and EDMUND A. SCHADE, citizens of the United States, residing at New Britain, county of Hartford, State of Connecticut, have invented certain new and useful Improvements in Planes, of which the following is a full, clear, and exact description.

Our invention relates to a new type of plane adapted to a wide range of work but especially adapted to enable the user to form shallow mortises for hinges, lock face plates, latch strike-plates and the like, with the greatest ease and accuracy. The tool is also designed in such manner that hinge mortises in the jamb and on the edge of a door may be formed without the necessity of using a butt gage, since the plane is equipped with a gage that obviates the use of a separate instrument for the marking out of the mortises. The construction is also such that a mortise may be readily formed in a rabbeted door jamb close to the face of the strike or stop, while the cutter arrangement and length of the plane allows of the forming of a mortise from one and a half inches in length to six inches in length, and also within a few inches, for example, five inches, of the upper casing or lower sill of a door casing. By a very simple adjustment, mortises longer than six inches may be made. The plane may also be used to advantage as a router, and, in the particular form shown herein, can effectively work two inches below the sole of the tool, thus giving a greater range of effective operation than possible with the ordinary router plane. With this outline, it will be seen that the plane is capable of a wide range of usefulness.

In the drawings Figure 1 is a side elevation of the plane. Fig. 2 is a plan view thereof. Fig. 3 is a section on the line x–x, Fig. 1. Fig. 4 is a side elevation of a detail. Fig. 5 is a section on the line y–y Fig. 4, looking up. Fig. 6 is a plan view of the cutter detached.

1–1a represent the two end sections of the sole of the plane.

2 is a connecting arch extending vertically from the plane of the sole sections 1–1a.

3 is a connecting arch extending horizontally from the sole sections 1–1a.

4 is a chip clearance passage between the arches 2–3.

5 is an upwardly extending tubular guide sleeve located above the arch 2.

6–6a are oppositely facing handles mounted on the two end sections 1–1a of the sole.

7–7a are bosses screw-threaded to receive horizontally extending guide rods 8–8a, when it is desired to use a gage.

9 represents a side gage having sleeves 10–10a arranged to slide upon the rods 8–8a respectively. The lower side of the arch 3 is smoothed off to form a continuation of the two sole sections 1–1a and to give a bearing of substantial width.

12 is a cutter connected to the lower end of an adjustable and slidable carrier post 13. This carrier post is mounted to slide up and down in the guide sleeve 5. The upper end of the carrier 13 is threaded and is provided with an adjustable stop 14 threaded thereon so that by rotating said stop, the downward projection of the carrier post 13 and cutter is limited.

15 is a spring arranged to press the carrier post 13 downwardly. In the preferred arrangement, this spring 15 is coiled around said post and rests at its upper end underneath the arch 2 and at its lower end against a washer 16, which may be rigidly connected to said post 13.

17 is a set screw which enters the guide sleeve 5 laterally, the inner end bearing against the carrier post 13 so that by setting up on said set-screw said post and cutter may be held against sliding movement up and down.

In the particular form shown, it will be seen that the side of the cutter carrier post 13 is provided with a plurality of longitudinal grooves 18–18.

19 is a spline carried by the guide 5, and in this instance hinged so as to be operated by a finger piece 20, said spline being suitably spring-pressed, as by a spring 21, to hold the spline projected into one of the grooves 18. In this instance, the spline and grooves are so placed that the cutting edge of the cutter 12 may be projected toward either end of the plane or laterally in either direction relative thereto. The cutter is preferably detachably connected to the carrier post 13 and is also preferably pitched downward at a slight angle. In this instance, the cutter has its upper surface cross-knurled, the lower end of the guide 13 being correspondingly knurled, so that by the aid of a fastening screw 22, said cutter may be rigidly secured to the lower end of the carrier post. As shown in Fig. 4, the cutter may have two screw passages, whereby, when the forward or cutting edge of the cutter, is worn back, the connection of the cutter to the carrier may be effected by passing the screw 22 through the second or rearmost screw passage.

In forming an ordinary shallow mortise for a hinge strike-plate or lock face-plate, incisions may be made by an ordinary chisel to determine merely the end lines of such a mortise. The gage 9 may be properly set and the cutter carrier post properly set so that it will project the cutter to the desired depth of said mortise, and no more. This being determined, the tool is then applied to the wood, and is preferably started close to the end line of the mortise facing the cutting edge of the cutter. A short chip is then taken. The operator works the plane back step by step until by taking out a succession of short chips he approaches the opposite end line of the mortise, whereupon, by pressing in on the finger-piece 20, the spline 19 is retracted and the cutter may be reversed to the position opposite from that shown in Fig. 1, whereupon the balance of the mortise may be formed without reversin the position of the plane on the piece being cut. During this operation, the cutter yieldingly engages the wood by reason of the spring pressure of spring 15, and will cut down to a depth corresponding to the desired depth of the mortise, at which depth it will be checked by the stop 14 aforesaid. When at the limit of this depth, the bottom of the mortise may be smoothed off by long strokes, so as to properly receive the part to be applied therein. By making the cutter carrier post 13 itself reversible, it is possible to work the tool in either direction in forming a mortise, without disturbing the position of the guide, and hence preserving the proper position of the cutter relatively to the mortise being formed. When the tool is to be used as a router, in some instances it is desirable to shift the tool so that the cutter will stand at right angles to the position shown in Fig. 1. This may be easily accomplished by releasing the spline 19 and shifting said carrier post 13 to the proper position. For routing at considerable depth, it may be desirable to lock the cutter post firmly against vertical movement. This may be accomplished by setting down upon the screw 17.

Obviously, cutters 12 of varying width may be substituted, depending upon the particular work to be performed and the character of wood to be operated upon.

In the above and in a variety of other ways, a mechanic skilled in the art of wood working will find this tool exceedingly useful and capable of performing, quickly and accurately, work which no other tool of the plane type is capable of performing.

What we claim is:

1. In a plane, two oppositely faced connected sole sections, an arch connecting said sections, a reversible cutter carrier, a guide in said arch for said cutter carrier, and means to permit said cutter carrier to move up and down in said guide during the operation of the plane, and disengageable means to hold said carrier against rotation at such times.

To all whom it may concern:

Be it known that I, EDMUND A. SCHADE, a citizen of the United States, residing at New Britain, county of Hartford, State of Connecticut, have invented certain new and useful Improvements in Planes, of which the following is a full, clear, and exact description.

My invention relates to an improved frog adjustment for a bench plane, whereby the frog, which is the means for supporting the plane iron, may be readily adjusted to and fro, and which, when locked in position, is rigidly held in such a manner as to reduce to a minimum any chance of slippage or displacement.

In the drawings, Figure 1 is a longitudinal section of a plane showing my improved adjustment. Fig. 2 is a section on the plane of the line x–x, Fig. 1, looking from left to right. Figs. 3, 4 and 5 are detail views. Fig. 6 is a longitudinal section of part of a plane of slightly modified construction from that shown in Fig. 1, my invention being applied thereto. Fig. 7 is a cross section on the line y–y of Fig. 6, looking from right to left. Fig. 8 is a longitudinal section of a part of a plane of another modified form. Fig. 9 is a cross section on the line z–z Fig. 8, looking from left to right. Fig. 10 is a longitudinal section illustrating still another modification. Fig. 11 is a cross section thereof on the line w–w looking from right to left.

Referring to Figs. 1 to 5, 1 represents a sole of an iron bench-plane which may be, as to general details, of conventional form. 2 is a frog bearing, in this particular instance formed on an incline directly to the rear of the throat 3. 4 is a frog adjustably mounted on the support 2 for movement to and fro relatively to the throat 3. 5 is a plane iron. 6 is a cap of conventional form and by which the plane iron may be clamped to the frog 4. The invention in this case resides primarily in the means for adjustably securing the frog 4 to the frog support 2. In this instance the frog is provided with two longitudinal slots or passages 7 in which stand clamping or gripping studs 8–8. These studs are headed, the headed portions standing above the slots, the opposite ends projecting down into cavities or recesses in the support 2. Each stud is transversely recessed toward its lower end, as indicated at 9. 10 is what I will term a cam stud, there being one for each gripping stud 8. The cam studs are arranged in the support 2, suitable bores being provided therefor, the rear ends of said studs being arranged to receive a suitable tool, for example, a screw driver, the forward end of each cam stud being provided with an eccentric projection or cam 11. This cam 11 projects into the recess 9 of the respective gripping stud. 12 is a slot in the side of each cam stud. Entering from the side of the plane is a locking screw 14, the same being so arranged relatively to the slotted portion 11 of the cam stud that the forward ends of each screw 14 will engage the wall at the base of the recess 12 at one side of, or eccentric to, the axis of the cam stud.

In the operation of the parts thus far described, it will be seen that by rotating the cam stud in the proper direction, the cam 11 will engage with the wall at the lower end of the recess 9 in the gripping stud so that said gripping stud will be pulled down into firm gripping engagement with the frog 4. To give a further set to the cam and to guarantee against disengagement, the screw 14 may be turned in until its nose engages eccentrically said cam stud, tending to turn it in a direction to increase the tension of the cam on the gripping stud and also preventing any rotation of the cam stud in a reverse direction to release said gripping stud. I have found, by this means, that the frog may be very quickly and easily adjusted, and, at the same time, when locked in position, is held with exceeding rigidity.

In the other views I have shown slight modifications. For example, in Figs. 6 and 7 I have shown the frog 4a as mounted upon a support 2a having a two-point bearing for the frog. In this case as before, the frog is held by means of gripping studs 8a operated by cam studs 10a which are in turn controlled by screws 14a.

In Figs. 8 and 9 I have shown a modification in which instead of providing the gripping studs 8 for holding the frog to its seat, I have provided the frog 4b with a plate-like extension 8b which is preferably cast into the frog, so as to be a permanent part thereof, said plate 8b having passages to receve the cam ends 11b of the cam studs 10b. In this case, as previously, the side screws 14b may be employed to cooperate with the cam studs for the same purpose as before.

In Figs. 10 and 11 I have shown a modification more particularly of the construction shown in Fig. 8 in that instead of anchoring the aforesaid plate in the frog, I have anchored a similar plate in the frog support. In these views, 8c represents said plate anchored in the support 2c, and in this case the cam studs 10c are carried in passages in the rear of the frog 4c, the cam ends 11c engaging the walls of the slot in the plate 8c in the same manner as the cam ends 11b engage the walls of the slot in the plate 8b, shown in Figs. 8 and 9. Here again take-up screws are employed, the same being indicated at 14c. In this case the take-up screws are carried by threaded bores in the sides of the frog, suitable windows or clearance openings 15 being provided in the cheek pieces of the plane to permit a screw driver to be entered sufficiently to engage the slotted ends of said screws 14c for the purpose of operating the same.

In both forms of devices shown in Figs. 8 to 11, a suitable clearance space is provided for the plates 8b and 8c respectively whereby there may be a relative movement between said plate and the part carrying the cam screw. In these cases, the cam ends 11b and 11c respectively should be of sufficient length to engage the plates 8b and 8c respectively in all of the various positions of adjustment.

What I claim is:

1. In a plane, a main body portion having a throat therein, a frog support at the rear of said throat, a frog adjustable to and fro thereon, a locking means for holding said frog in different positions of adjustment comprising a clamping member operatively engaged with one of said parts, means for operating said clamping member carried by the other part and comprising a rearwardly projecting cam stud coacting with said clamping member, and a lock and tightener for said cam stud, said lock and tightener comprising a laterally projecting exposed screw engaging said cam stud in a direction to turn the same as said lock and tightener is advanced.

2. In a plane, a main body portion having a throat therein, a frog support at the rear of said throat, a frog adjustable to and fro thereon, a locking means for holding said frog in different positions of adjustment comprising a clamping member operatively engaged with one of said parts, means for operating said clamping member carried by the other part and comprising a rearwardly projecting cam stud coacting with said clamping member, a lock for said cam stud, said lock comprising a laterally projecting exposed screw, and a shoulder on one side of said cam stud eccentric thereto, said screw engaging said eccentric shoulder and pressing against the same in a direction to turn said cam stud so as to more tightly engage the clamping member.

3. In a plane, a body portion having a throat, a frog support at the rear of said throat, a frog adjustable to and fro on said support and relatively to said throat, a clamping member carried by said frog and projecting into said support, said support having a recess therefor, a cam stud carried in said support and exposed at its rear end, an eccentric pin extension at the forward end of said stud eccentrically engaging said clamping member, and a lock screw for engaging said clamping stud at one side and arranged laterally thereto.

4. In a plane, a body portion having a throat, a frog support at the rear of the throat, a frog mounted for adjustment to and fro on said support, said frog having a fore and aft slot therein, a clamping stud passing downwardly through said slot into said support, an operating device for said clamping stud comprising a cam stud mounted in said support, an eccentric pin projection at the forward end of said cam stud eccentrically engaged with said clamping stud, and a lock for said cam stud.

5. In a plane, a body portion having a throat, a frog support at the rear of the throat, a frog mounted for adjustment to and fro on said support, said frog having a fore and aft slot therein, a clamping stud passing downwardly through said slot into said support, an operating device for said clamping stud comprising a cam stud mounted in said support, an eccentric pin projection at the forward end of said cam stud eccentrically engaged with said clamping stud, and a lock for said cam stud, said lock comprising a screw entering said frog support from the side of the plane.

To all whom it may concern:

Be it known that I, CHRISTIAN BODMER, a citizen of the United States, residing at New Britain, county of Hartford, State of Connecticut, have invented certain new and useful Improvements in Wood-Scoring Devices for Planes and the Like, of which the following is a full, clear, and exact description.

My invention relates to improvements in wood cutting instruments such as planes and the like, the object being to provide in such constructions a scoring device or spur to partially cut the wood in advance of the plane iron.

A valuable incident of this invention is the provision of means whereby the scoring device or spur may be adjusted to cause said cutting edge to project to a greater or lesser degree from the main body of the instrument to make a shallow or a deep cut as required and to also compensate for variations in length of the spur due to sharpening the latter from time to time.

In the drawings: Figure 1 is a side elevation of a plane of the plow type fitted with my improved scoring device or spur; Fig. 2 is a relatively enlarged detail view of the spur in operative position; Fig. 3 is a similar view showing the spur in non operative position; Fig. 4 is a section on the line x–x of Fig. 2.

The wood cutting device of the type illustrated in Fig. 1 is a species of plane in which 1 is the plane body; 2 is the sole portion thereof provided with the usual throat in which is located the cutting iron 3. In advance of the cutting iron is located a spur, said spur being arranged in a recess 4 in the side of the sole 2. The spur is held by a screw 5. The spur construction itself comprises the cutting end 6 and the head 7. The head 7 is of circular outline preferably and has a central perforation in which a holding screw 5 is located, said screw taking into a threaded opening in the sole 2. The recess 4 has its intermediate portion conformed to the circular part or head 7 of the spur, thereby relieving the screw in a large measure of strain. Above and below this circular part the recess is extended to receive the cutting end 6 of the spur.

As shown in the detail views Figs. 2 and 3, the ends of the recess 4 are diagonally arranged with reference to the base of the sole 2. The outer edge of the spur is arranged obliquely to a radial line from the center of the screw 5, the cutting edge itself being preferably somewhat rounded as shown and sharpened so that said cutting edge proper will lie approximately in the plane of one side of the cutter 3, whereby, when the plane is pushed forwardly, the spur will score the wood directly in advance of one edge of the cutter 3. A corresponding spur may be arranged on the opposite side of the sole 2 to score a corresponding line in line with the opposite edge of the cutter 3. Since these spurs correspond a description and illustration of one is sufficient for both. The lower end of the recess 4 is widened somewhat so as to permit the spur to be swung upon its screw mounting 5 whereby by swinging said spur its cutting edge may be projected more or less as desired. By the particular arrangement shown a forward movement of the plane across a board will produce through the medium of the spur a score line corresponding in depth to the extent to which the spur is projected.

By reason of the method of mounting the spur there is little or no danger of dislodgment of the same after it has been adjusted, the cut of the spur being an easy draw cut. By this means all chattering of the parts as the plane is advanced over the wood is avoided. The cutting edge 6 of the spur being formed on a plane oblique to a radial line from the center of the screw 5 permits the said spur to be sharpened from time to time without grinding away such a portion of the cutting edge as to render it ineffective. Since even though a portion is ground away, the cutting edge of the spur may be projected to the desired extent by the swinging movement above referred to. When it is desired to omit the spur, it is simply necessary to withdraw the screw 5 somewhat and swing the spur from the position indicated in Fig. 2 to that indicated in Fig. 3, the cutting end of the spur being then housed in the upper end of the recess 4 and flush with the outer side of the sole.

What I claim is:

1. In a plane, a main body having a sole portion, a scoring device comprising a spur having a head portion, a screw passing through said head portion arranged to adjustably hold said spur against said body, the cutting end of said spur extending radially from said head portion, the cutting edge of said cutting end being arranged obliquely to said radius, an inclined recess in said body arranged to receive said spur, the lower part of said recess being wider than the cutting end of said spur to permit the cutting edge of said spur to be projected more or less by an angular shifting of said spur in said recess.

2. A scoring device for a plane or the like comprising a spur having a main body of circular outline, a central passage arranged to receive a holding screw, a cutting portion extending radially from said main body, the cutting edge of said cutting portion being oblique to the radius, a plane body having ca sole portion, a recess in the side of said portion arranged to receive said scoring device, a portion of said recess being shaped to snugly receive the main body of the scoring device, another portion of said recess extending downwardly and rearwardly from the first mentioned portion and being wider than the cutting end of said spur to permit the latter to be adjusted by the shifting of said spur angularly relatively to the center of the head and a holding screw arranged to pass concentrically through the head into the sole portion of said body.

3. In a plane, a main body having a sole portion, a scoring device comprising a spur, a screw passing through said spur and arranged to adjustably hold said spur against said body, said spur extending radially from said screw, said spur having at its outer end a cutting edge, said cutting edge being oblique to the radius of said spur, said body having a recess in its side arranged to receive said spur, the lower end of said recess being wider than said spur to permit the cutting edge of the latter to be projected more or less by an angular shifting of said spur in said recess.

4. A scoring spur for planes, a main body portion having a screw passage and having a radially extending arm at one side of said screw passage, a cutting edge at the outer end of said arm, said edge being oblique to the radius of said arm, one end of said edge being nearer to the said screw passage than the other end of said edge.

To all whom it may concern:

Be it known that I, CHRISTIAN BODMER, a citizen of the United States, residing at New Britain, county of Hartford, State of Connecticut, have invented certain new and useful Iinprovements in Dovetail Tongue and Groove Cutters, of which the following is a full, clear, and exact description.

My invention relates to an improved means in the nature of a plane for forming dovetailed or undercut tongues and grooves.

The object of the invention is to provide a means for performing the above function which shall be so constructed as to permit the forming of such tongues or grooves with the greatest facility and accuracy.

In the drawings, Figure 1 is a side elevation of the tool assembled and adjusted for the purpose of forming an undercut groove. Fig. 2 is a rear end elevation of Fig. 1, showing the tool as it appears in the act of forming a groove. Fig. 3 is an end elevation of the tool assembled and adjusted for the purpose of cutting a tongue. Fig. 4 is a side elevation of the main body and certain parts on a somewhat reduced scale. Fig. 5 is a view of the reverse side of the parts shown in Fig. 4. Fig. 6 is a sectional view on the line x–x of the Fig. 4, looking in the direction of the arrow. Fig. 7 is a side elevation of a guide frame, arranged for association with the main body of the plane. Fig. 8 is an end view of the guide frame shown in Fig. 7. Fig. 9 is a side elevation of a detail. Fig. 10 illustrates another detail in diderent positions. Fig. 11 is a side elevation of another guide frame arranged for association with the main body of the plane. Fig. 12 illustrates three different sizes of plane irons, on the scale indicated in Fig. 4. Fig. 13 is a side elevation of a detachable spur carrier.

1 is the main body or cutter carrier of the tool, the same being provided with a handle 1a and with a long narrow sole 1b.

2 is a cutter or plane iron, the cutting edge of the same being adjustable in a throat in the sole 1b.

3 is a clearance outlet for shavings or chips and located above the aforesaid throat.

4 is a clamp screw for locking the cutter in various positions of adjustment.

The cutter is located in a channel arranged obliquely in the side of the main body 1.

5 is a clutch operated by screw 4, for wedging down upon the cutter 2 when the latter is in position to prevent its unintentional or accidental dislodgment.

The oblique channel for receiving the plane iron is so arranged as to support the upper and lower surface of the shank of the cutter, the lower side of that part of the cutter opposite the recess 3 being supported on the incline 6. As will later be seen, cutters having cutting edges of different widths may be substituted, but to secure the best results the shank portion of each cutter should be substantially alike, the variations in sizes occurring at and directly above the cutting edge.

As will be seen by Figs. 2 and 3, the sole 1b of the body 1 is formed at an oblique angle to the opposite side walls thereof and in practice it is obvious that the edge of the cutter should be shaped to correspond.

7–7a are spurs arranged on opposite sides of the main body 1, both spurs being arranged to be projected to any desired degree or to be entirely retracted as desired. The function of said spurs is to score the wood in advance of the cutter 2, whereby, when said tool is used across the grain, the score lines made by the spurs 7–7a will prevent splintering the wood, thereby enabling the cutter 2 to plow out or to cut a clean channel. It should be stated that the width or thickness of the sole edge of the main body 1 is not greater than the minimum width of the smallest channel which it is possible to form.

The foregoing is a general description of the main body or cutter carrier element of the tool.

8 is the main body portion of what I term the composite guide frame, which frame is arranged for association with the cutter carrier 1 for the purpose hereinafter described.

8a is the side flange of the frame 8, said side flange being arranged obliquely to the sole 8b of said frame.

9 is an upright slot in the fiange 8a terminating at its lower end in an opening 9a.

10–10a are bosses, having passages therein at right angles to the sole 8b of the guide frame 8.

11–11a are set screws carried by the bosses 10–10a respectively.

12 is a thumb piece arranged to receive the thumb of the operator to facilitate the operation of the tool.

14 is a headed stud carried by the main body of the cutter carrier 1, the shank of said stud standing in the upright slot 9 of the frame 8 when the parts are assembled.

15 is a scale at one side of the slot 9.

16 is a gage arranged to co-act with the scale for the purpose hereinafter described. The gage 16 has a slot 16a. 17 is a set screw passing through slot 16a and into the body of the cutter carrier 1, whereby said gage may be adjusted up and down, said scale facilitating said adjustment.

18–18a are threaded holes arranged fore and aft in the body 1 of the cutter carrier, these threaded holes being arranged to receive the two guide posts, spaced apart properly to register with the sockets 10–10a of the guide 8. One of these guide posts is shown at 19, Fig. 3. These guide posts may be readily applied or removed by simply turning the screw end of each into the threaded openings 18–18a. These guide posts are used only when the tool is asembled for forming a tongue.

It will be observed that the stud 14 is arranged directly above the cutting edge of the plane iron 2, the purpose of this being later seen.

I will now describe the tool as assembled and employed in forming an undercut or dovetail groove. In this connection particular reference is directed to Figs. 1 and 2. In these figures it will be seen that the cutter carrier 1 is combined with the guide frame 8 and it may be assumed that the gage 16 is secured by the screw 17 on the scale 15 at the proper elevation to limit the depth of the cut. The intention now is to form a dove-tail groove in a piece of wood indicated at 20 (Fig. 2). To do this, the location of the groove is determined and a guide cleat 21 is tacked down to said piece of wood in a line parallel to the groove to be formed, and at one side thereof a distance corresponding to the width of the bottom of the sole 8b of the guide frame 8. The tool is then placed in the position indicated in Fig. 2 bearing against the cleat 21 and is moved to and fro until the cutter has descended into the wood 20 to the desired depth determined by stop 16. In forming this cut, both spurs 7–7a should be turned down, particularly if cut is to be made across the grain. The cutter carrier 1, being connected to the guide frame 8 only by the stud 14, may take an oscillating movement relatively to the guide frame 8 and hence may follow any warped portion of the wood in which the cut is being formed. By reason of the location of the stud connection 14 relatively to the cutter 2, the oscillating movement of the carrier relatively to the guide frame will not permit the cutter 2 to descend into any part of the wood 20 more than the amount predetermined by the gage 16. When an oblique groove has been cut as indicated in Fig. 2 the tool is removed and the cleat 21 is taken off and tacked down on the opposite side of the groove as indicated in dotted lines, being spaced apart from the adjacent edge to be of the groove a distance corresponding to the width of the bottom of sole 8a of the guide frame. The instrument is then turned around and operated as first described, the cutter 2 working down in the wood until the balance of the intended dove-tail groove is formed, as indicated in the dotted lines, Fig. 2. In forming this last part of the groove, it is unnecessary to employ the spur 7a which may be turned back into the position shown in Fig. 5, a recess in the said main body 1 receiving the same, so that it will stand flush, the spurs themselves being held in all positions by ordinary machine screws. The spur 7a will be seen to be unnecessary at this time because as the cutter descends, the wood on that side of the plane iron (the side toward the spur 7a) has previously been cut away in forming the first part of the groove, hence no chipping or splintering is possible on that side.

In forming a dove-tail tongue, another adjustment is employed, namely, the right angle guide 22, the same being substituted in the place formerly occupied by the guide 8, which latter is transferred to the opposite side of the frame 1 (as shown in Fig. 3) and mounted upon the posts 19–19, the sole 8b of the said guide 8, being spaced apart from the opposite side of the cutter carrier 1, a distance corresponding to the depth of the tongue to be formed. 23 represents the piece of wood upon which the dove-tail tongue is to be formed, said tongue portion being indicated at 24. The gage 16 is now adjusted on the scale 15 to such a position as to properly limit the descent of the cutter carrier 1. The instrument is placed in the position indicated in the Fig. 3, and moved to and fro. The right angle guide 22 cooperates with the guide 8 in holding the cutter carrier 1 in the proper position to cause the cutter to enter the wood as shown in Fig. 3, in which one-half of the tongue is represented as completed. In performing this work, the guide 8 obviates the use of a batten such as 21, although the latter could be used if desirable. To form the other half of the tongue 24 (indicated by dotted lines), the piece of wood 23 is simply turned over and the tool is used on the opposite surface in the same manner. In the formation of the tongue only one spur need be employed, namely the spur 7.

From the foregoing it will be seen that a dove-tail groove and a tongue of corresponding size and cross section may be formed with the greatest accuracy and ease.

Thus far I have described the device as fitted to produce tongues and grooves of the minimum size. When it is desired to produce a tongue and groove of greater size it is merely necessary to substitute a cutter having a cutting edge of greater width than the thickness of the sole 1b of the cutter carrier. When such wider cutter is employed it is obvious that one edge of the same will project beyond one side edge of the sole 1b, and in such an event, in order to provide a spur adjacent to that edge of the cutter, a supporting spur carrier or spacer 25 may be secured to the adjacent side of the main body 1. An illustration of this spacer 25 with the spur 7a is indicated in Fig. 13 and its construction is too obvious to require detailed description. The spacer 25 may be secured to the main body of the cutter by screws which may screw into threaded openings 27–27, Fig. 4.

28 is a projecting stud or screw head, which is arranged below the stud 14, the width of said screw head 28 being less than the width of the slot 9. This projecting head 28 is preferably employed to prevent unnecessary oscillation of the guides 8–22, relatively to the main body 1 of the plane iron carrier, but obviously it may be dispensed with.

In Fig. 12 I have shown cutters 2, 2a, 2b of three different sizes, said cutters being on a scale adapted to the scale of Figs. 4 and 5.

The frame 8 I have termed a composite guide, since it may be applied to either side of the cutter carrier. While in the drawings the outer edge of the guide 8 is shown as straight to furnish a bearing to parallel the sole of the cutter carrier, obviously this and other features may be modified in a variety of ways, so long as the results described are accomplished by means equivalent to those shown and in substantially the same way.

To all whom it may concern:

Be it known that I, CHRISTIAN BODMER, a citizen of the United States, residing at New Britain, county of Hartford, State of Connecticut, have invented certain new and useful Improvements in Planes, of which the following is a full, clear, and exact description.

My invention relates to planes and particularly to that type of plane known as a fillister or rabbet plane.

The invention has particular reference to the construction of the plane body, my object being to overcome certain weaknesses that have heretofore existed in planes of this type.

In a fillister or rabbet plane, the cutting edge of the plane-iron is made the full width of the sole, or so that the side edges of the plane iron will be coincident with the sides of the plane, whereby the cut may be formed square up to each side edge or surface of the plane body. It follows that the throat or opening in the plane sole must therefore be the full width of the sole. This results in separating the sole transversely at a point intermediate its length, and places, therefore, the entire responsibility of holding the forward and rear sections of the sole in proper spaced relation upon the single side plate of the frame. It is at this point that heretofore has not only great weakness existed, but in the casting of the plane body great difliculty has been encountered in preventing warping and twisting of the parts, tending to throw the sections out of correct alinement and making the process of machining not only laborious but exceedingly difficult. By my improvement great strength is added at this point, warping and twisting during the process of casting are prevented, and machining is simplified and expedited. The plane body is made from cast iron and since this tool is usually a hand tool, it is obvious that it must be so constructed as to withstand severe usage. Heretofore planes of this type made from cast iron as in the present case have almost always been broken across the relatively narrow connection between the two sections of the plane. By my construction such a greater degree of strength is added that there is very little danger of breakage at any point even when the tool is roughly handled. The tool being a hand tool, it is obvious that great consideration must be attached to the element of weight, since unnecessary weight unduly taxes the strength of the workman. In this connection I have constructed a plane body so that the metal is economically disposed and well balanced throughout, my aim being to secure the highest degree of stability with a mininium amount of material.

In the accompanying drawings, Figure 1 is a side elevation of the complete plane, looking up from the left hand side. Fig. 2 is a view of the reverse or right hand side of the plane body. Fig. 3 is a plan view of Fig. 2. Fig. 4 is a relatively enlarged view showing a part of the plane in longitudinal section. Fig. 5 is a cross section of the plane on the line x–x. Fig, 6 is a cross section of the plane on the line y–y.

The plane body is cast in iron or steel and comprises the forward sole section 1 and the rear sole section 2, separated by a throat 3, in which the cutting edge of the plane-iron 4 stands when the plane is set up and adjusted ready for use.

5 is a seat for the plane-iron.

The throat 3 extends transversely and obliquely entirely across the plane body as best seen in Fig. 1, and it follows therefore, that the seat 5 not only inclines rearwardly but slants down toward one side of the plane. Any suitable mechanism may be employed for holding the plane-iron to the seat, such as the headed screw-stud 6 and the cap 7. The two sections 1–2. of the sole are integrally connected by a side plate 8 formed in this instance at the right hand side of the body, a part of the side plate bridging the throat 3 and being constructed, as hereinafter described, to afford great strength and to prevent warping and twisting. The plate 8 is provided with a raised bearing portion which is machined smooth, as indicated by the laterally offset ribs 8a–8a. These bearings 8a are raised with reference to the plain unfinished side of the said side plate 8, the area of said bearing portion being suflicient to afford a sufficiently long and broad seat, at the same time being much less than the entire area, thus simplifying exceedingly the operation of machining.

9 is an upwardly projecting bearing support at the opposite side (the left hand side) of the plane body, the same being in this instance parallel with the bearing portion of the side plate 8, and at right angles to the plane of the sole sections 1–2. This bearing-section 9 is connected integrally not only with the sole section 1, but also with the opposite side plate 8, said last connections being effected through the medium of the bridge rib 10.

11 is a handle preferably cast integrally with the plane body, but of course may be made capable of being connected to said plane body in any well known or desirable manner.

Referring particularly to the views 4–6, the connections between the throat and the rib sections of the plane will now be described. It is to be understood that the plane-iron, in this type of plane, is widest at its lower end, its middle and upper portion being narrowed down to clear the side plate 8. In the present instance, I avail myself of this feature to specially construct the bridge connection between the two sole sections, providing, where necessary, a solid strong mass of material and wherever possible a ribbed construction to secure the necessary strength and lightness. Immediately adjacent to the plane seat 5, where the side plate 8 leaves the rear section, I provide a relatively heavy mass of stock, as indicated at 12, Fig. 6. Immediately forward of this point, the bridge is arched up as indicated at 13, said arch descending at a point slightly forward of the plane of the throat and meeting the transverse bridge 10 which extends across to the opposite side-bearing or support 9. The lower part of the solid mass of material 12 near the lower end of the seat 5 is extended forwardly to form a curved rib 14, which performs the double function of a strengthening rib for the plane body and a deflector for the shavings, there being a clearance space 15 entirely through the plane body above the throat 3. This rib 14 curves forwardly and across the plane and meets the sole section 1 and the inner side of the support 9, being integrally formed with both of said parts. The arched portion 13 is provided with a recess or cavity 13a and between this recess or cavity 13a and the base of the rib 14 is a horizontally disposed strengthening rib 16, extending back to the heavy mass of material 12, and serving, together with the upper flange of the bridge 13 and the rib 14, to provide a connection between the sections 1–2 of maximum strength and minimum of weight. The inside of the plane body is of course hollowed out as at 17–17 to lighten the structure.

18–18 are scoring spurs or cutters employed on opposite sides of the plane to form score lines in advance of the plane-iron 4, said score lines being coincident with the opposite edges of said plane-iron.

The part 9 performs, in addition to the function of bearing for the adjacent side of the plane, the function of a support for a depth gage, such as is customarily employed in planes of this character. The opposite side (right hand side) plate is provided with a supporting portion 8b, upon which a depth gage may be adjustably supported. Since gages and other plane attachments are well known, no particular description is required herewith, it being merely proper to state that the part 8b performs not only the function of a bearing, but also a support for any attachment such as is customarily employed in tools of this character.

As has already been stated, my invention aims at producing a plane body of the type referred to which shall be accurately formed. One of the great difficulties to overcome I will now describe. It is a well known fact that the machining of the outer flat face of a casting releases the surface tension and permits the tension on the opposite (unmachined) face to act in such a manner as to twist and warp the structure; to illustrate, were it not for the recessed form of the outer face of the side plate 8, the machining of that side to produce a bearing surface would release the surface tension on the outer side and result in warping and buckling, tending to distort and throw out of line the two sole sections 1–2 of the plane body. This buckling would occur during or immediately following the machining process. To avoid this disastrous effect, I provide a construction which requires the machining of such a relatively small area of the surface 8 that the surface tension is not released to any dangerous extent. Consequently, the tension being substantially balanced on the opposite surface of the side plate 8, all tendency to injurious warping or twisting is eliminated. It should be stated that the unmachined held of surface metal between the bearing faces 8a of the side plate 8 affords more than a mere panel intended only for the reception of a name or number. In the present instance, this unmachined surface of substantial area is so located as to overcome the aforesaid injurious tendency of warping by reason of the lessening of the surface tension at the vulnerable point.

A further advantage growing out of this construction is the rapidity and ease with which this machining process may be effected. The sum of these advantages results in great economies that add to the durability or accuracy of the instrument.

While of course I have shown herein the preferred embodiment of my invention, it is obvious that in some respects the construction may be modified or varied without changing materially those features of improvement which characterize my invention. Hence it may be stated that I contemplate that reasonable latitude may be had in the particular design resorted to.

What I claim is:

1. A plane body formed of cast metal including two sole sections separated by a throat, a wall or plate integrally connecting said sections by an arch at one side of the plane body and including a plurality of substantially horizontally disposed and inwardly directed spaced ribs extending laterally across the plane body, a standard at the opposite side of the plane forming a bearing support projecting upwardly from the forward sole section and connected to the last mentioned rib, and still another rib extending across the plane body from the support on one side to the plate on the other side and forming a combined deflector and strengthening rib.

2. A plane body formed of cast metal including two sole sections separated by a throat, a wall or plate integrally connecting said sections by an arch at one side of the plane body and including a plurality of substantially horizontally disposed and inwardly directed spaced ribs extending laterally across said body, a standard at the opposite side of the plane forming a bearing support projecting upwardly from the forward sole section and connected to the last mentioned rib, and still another rib extending across said body from the support on one side to the plate on the other side and forming a combined deflector and strengthening rib, said last mentioned rib being also integrally connected with said bearing support and one of said sole sections.

3. A plane body formed of cast metal including two sole sections separated by a throat, a wall or plate at one side, connecting said sections by an arch at one side of the plane body, a standard at the opposite side of the plane forming a bearing support, the inner side of said standard being integrally connected to the inner side of said wall or plate, the outer or bearing side of said plate where said arch is formed having a relatively raised bearing surface, said bearing surface being machined, the relatively unraised portion being unmachined to balance surface tension on opposite sides of said plate at said arch.

4. A plane body formed of cast metal including two sole sections separated by a throat, a wall or plate connecting said sections at one side of the plane body and including a plurality of substantially horizontally disposed ribs at the inner side of said side plate, the outer or bearing side of said side plate having a relatively raised bearing surface, said bearing surface being machined, said unraised portion being unmachined, said unmachined surfaces being so disposed relatively to the forward and rear sections of the sole portions of the plane as to retain surface tension at the point where buckling would tend to occur between the two sole sections.

5. A plane body comprising a forward sole section and a rear sole section arranged in line and separated by a narrow throat, a wall or plate connecting said two sections at one side of the plane body, all of said parts being formed integrally by casting, the outer bearing surface of said wall or plate including a smoothed machined bearing surface and an umnachined surface arranged in a plane slightly below the plane of the bearing surface, said unmachined portion being so located with relation to the forward and rear sole sections as to retain surface tension at the point between the front and rear sole sections where buckling would tend to occur.

To all whom it may concern:

Be it known that I, EDMUND A. SCHADE, a citizen of the United States, residing at New Britain, county of Hartford, State of Connecticut, have invented certain new and useful Improvements in Planes, of which the following is a full, clear, and exact description.

My invention relates to improvements in planes.

The object of the invention is to provide a simple and effective means to facilitate the adjustment of the plane frog to and fro for the proper positioning of the cutting edge of the plane iron in the throat of the plane.

In the drawings — Figure 1 is a longitudinal section of a plane taken approximately on the plane of the line x–x of Fig. 2, certain parts being shown in elevation; Fig. 2 is a cross section of the body of the plane on the line y–y, Fig. 1, showing a portion of the plane frog in elevation; F ig. 3 is a view of the under side of the forward part of the plane frog; Fig. 4 is a plan view of that part of the body of the plane which supports the frog.

1 represents the sole of the plane body; 2 the throat therein, and 3–3 are the cheek pieces. Immediately to the rear of the throat 2 is a smooth bearing support 5 designed to receive a cooperating bearing surface 7 at the forward end of the frog 6. Still farther to the rear of the throat 2 is an elevated bearing support 8, the rear portion of which is constructed to receive and support a cooperating bearing surface 9 on the frog. The bearing supports 5–8 are spaced apart so that the frog will be supported at two different points.

10 is a longitudinally arranged guide and strengthening rib on the upper side of the sole of the plane extending rearwardly from a point at or near the throat 2.

11 is a groove or slot in the under side of the frog, the side walls of which are arranged to take a bearing upon the side walls of the rib 10 whereby said rib 10 will serve to hold the frog in correct aiinement and guide the frog in its movement to and fro, thereby avoiding any twist or lateral displacement of the frog as it is being adjusted.

12–12a are longitudinal slots in the frog, parallel with the groove 11 but somewhat to the rear of the same. These slots are arranged to receive clamping screws 13–13a respectively. The lower ends of these clamping screws take into threaded openings 14–14a respectively in the sole of the plane which openings are arranged forward of the most elevated portion of the support 8.

15 is an adjusting screw carried by the sole of the plane at the rear of and below the bearing 8. This screw has a groove 15a arranged to receive a yoke 16, which is secured to the rear of the frog. When the screw 15 is moved to and fro, it will impart a corresponding movement to the frog.

17 is the plane iron or cutter held in place on the frog by the usual cap 18.

In operation, the frog is secured in place by means of the screws 13–13a, the same being set down snugly so as to prevent accidental or unintentional displacement of the frog. The strain of these screws, as shown, comes upon an intermediate part of the frog between the supports 5–8. The plane iron and cap are then applied. The adjustment of the plane iron for the purpose of projecting or retracting the cutting edge of the same may be accomplished in any well known manner, that being immaterial to my invention. If it is found that the position of the plane iron, fore and aft, in the throat 2 should be changed, it is merely necessary to move the screw 15 in the proper direction and to the desired extent, producing thereby the desired movement and adjustment of the frog. If by chance (and it is practically impossible to prevent it) one of the screws 13 or 13a is screwed down more tightly than the other, it is obvious that any movement to and fro of the frog would tend to twist the same upon its bearing supports by reason of an abnormal drag on one side of the center line. The provision of the guide rib 10 which fits between the guide walls of the groove 11 will prevent this displacement. I have found that even though the screws 13–13a be screwed down very tightly nevertheless adjustment of the frog by means of the screw 15 alone may be readily effected, due doubtless to the smooth bearing supports 5–8 and the co-acting smooth bearing surfaces 7–9 and to the fact that there is sufficient elasticity or spring in the frog along the line of the clamping screws 13–13a to prevent the absolute locking of the frog. While the clamping engagement of the screws 13–13a is not sufficient to prevent the intentional adjustment of the frog by the screw 15, said clamping engagement is quite sufficient to prevent accidental or unintentional displacement of the frog, particularly as in this respect the guiding rib 10 and the adjusting screw 15 cooperate with the clamping screws 13–13a in the retention of the frog in any of its adjusted positions.

l am aware that heretofore separated frog supports, adjusting screws, clamping screws and reinforcing ribs are old but in the present instance I have added a new function to the reinforcing rib, viz., the guiding function, and have thereby produced a means for permitting the quick and accurate adjustment of a plane frog, which means is vastly more simple and far more effective than any adjusting means heretofore produced in that it eliminates certain parts and operations heretofore regarded as essential, simplifies the act of adjusting, and guarantees a straight line movement of the frog to and fro. ln devices of this character it is desirable that the plane iron should be in position when the adjustment of the frog is being effected. By my improvement this is possible.

It is obvious that the number of guiding ribs 10 employed may be increased, but one is sufficient, and is, indeed, preferable. It is obvious that the rib 10 may engage the side walls of the groove 11 throughout their entire length, but in the preferred form it is desirable to cut back or narrow the top of the rib to the rear of its front end, so that the active guiding part of the rib is comparatively short and close to the throat. By this arrangement a slight lateral adjustment of the extreme rear end of the frog may be had in assembling the plane, only a very slight adjustment at this point ever being required (if at all) to secure the accurate positioning of the frog on the supports 5 and 8 relatively to the throat.

In practice I accomplish the proper positioning of the frog on its support in the following manner: Before tightening up the screw which holds the fork in its place, I place the forward end of the frog in its proper position upon the rib and then swing the rear end of the frog to right or to left as may be necessary to secure perfect alinement between the frog and center line of the plane bottom. During this swinging movement the fork 16 (loose on its own fastening screw) engages the circular groove 15a. When perfect alinement is secured, I force home the screw which holds the fork, thereby securing all the parts in cooperative combination. In this way the fore and aft movement of the frog on the plane bottom is made to be in perfect alinement throughout. When the fore and aft movement is secured in this manner the front edge of the frog is always parallel to the throat of the plane. This method is found to be advantageous in practice, although it is evident that with sufficient pains the proper cooperative relations of the frog and plane bottom may be secured even if the fork were firmly fastened in the first instance.

It is evident that yoke 16 and the adjusting screw 15 may be reversed, that is to say, the yoke may be secured by a screw to the bottom of the plane and the adjusting screw be inserted in the rear of the frog, these two elements cooperating with each other in the same way, whichever one of them may be uppermost. Likewise the fork may be cast integral with the portion of which it is a part.

What I claim is:

1. A bench plane comprising a body portion having a transverse throat in the sole portion thereof, a frog support to the rear of said throat, a frog mounted thereon for adjustment to and fro, means for frictionally clamping said frog to said support, a combined guide and operating means located at and accessible at the rear of the frog for moving said frog on said support longitudinally of the plane body, and a guiding rib and groove engagement between said frog and support adjacent to the throat of the plane whereby said frog will be prevented from twisting out of correct alinement relatively to the throat as it is adjusted to and fro.

2. A bench plane comprising a plane body having a transverse throat in its sole portion, a frog support, a frog mounted thereon, means for frictionally clamping said frog to said support on both sides of the central vertical plane thereof, and intermediate its forward and rear ends a single positively operating means for adjusting said frog on said support longitudinally of said plane, and a guiding rib and groove engagement between said frog and support at the forward end of the frog and adjacent to the throat of the plane whereby the said single adjusting means will move the frog parallel with said central vertical plane regardless of difference of degree of clamping between said clamping means.

Be it known that I, EDMUND A. SCHADE, a citizen of the United States, residing at New Britain, county of Hartford, State of Connecticut, have invented certain new and useful Improvements in Planes, of which the following is a full, clear, and exact description.

My invention relates to improvements in planes, the main object being to provide superior adjusting means.

In the accompanying drawings, Figure 1 is a longitudinal section of the body of a plane and certain parts, showing also certain other parts in side elevation, this section being taken on approximately the line W–W Fig. 2. Fig. 2 is a cross-section on the line X–X Fig. 1, looking in the direction of the arrow. Fig. 3 is a cross-section on the line Y–Y Fig. 1, looking in the direction of the arrow. Fig. 11 is a cross-section on the line Z–Z Fig. 1, looking in the direction of the arrow. Fig. 5 is a central longitudinal section of certain parts of the plane. Fig. 6 is a longitudinal section taken on the same plane as the section of Fig. 1 and showing a modiication. Figs. 7 and 8 are side elevations of companion parts. Fig. 9 is a side elevation of a modified part.

This saddle 3 furnishes a support for the frog 4, upon which is mounted the plane-iron 5, the same being secured thereto by the well known clamp 5a not necessary to describe in detail herein. The forward or cutting edge of the plane-iron 5 projects through a throat 6 in the sole of the plane. In the particular form shown, the saddle 3 is provided with a rib 7, which enters a groove in the lower end of the frog 4 and so fits the same that it operates as a guide to guarantee an accurate fore and aft movement of the frog relatively to the longitudinal axis of the plane while adjustment is being effected. The frog is suitably shaped to rest upon the saddle 3 so that it may be adjusted back and forth, thereby shifting as desired the cutting edge of the plane-iron 5 forward and back in the throat 6. The usual adjusting mechanism to vary the projection of the plane-iron may be provided, but, since the same constitutes no part of this invention, it need not be described herein.

The particular feature of invention herein disclosed relates to the adjustment of the frog, whereby the throat clearance may be varied. To accomplish the adjustment of the frog, I provide an adjusting screw 8 mounted at the rear of the saddle 3 and operating to and fro. A forked plate 9 carried by and at the rear of the frog 4 stands in an annular groove in the head of the screw 8 so that as the screw 8 is operated to and fro, it imparts a corresponding movement to the frog, provided the latter is not locked in place. To lock the latter in place, I provide a simple and effective clamping mechanism comprising (in the form shown in Figs. 1 to 4 and 6 and 7) the tubular shank 10 arranged vertically in a suitable bore in the saddle 3. As shown, two of these tubular shanks 10 are provided and each of these shanks is preferably threaded to receive a screw 10a, the shank of each screw standing in a longitudinal slot 4a in the frog 4.

11–11 are set-screws which pass into the rear of the saddle 3 so as to be easily accessible from the rear. These screws preferably have conical noses at the forward end, which pass into recesses in the side of each sleeve 10 so that when said screws 11 are advanced they will operate to force the sleeves 10 down so as to clamp the heads of the screws 10a tightly against the frog, in turn drawing the frog hard down against the saddle 3. Ordinarily, in planes of this character, it has been necessary, in order to adjust the frog, to remove the plane-iron 5. Inasmuch as the degree of throat clearance cannot be accurately and quickly determined when the plane-iron is removed, it follows that an adjusting device which is accessible and operable when the plane-iron is in place, furnishes an exceedingly valuable improvement.

By my invention all that is required is to simply loosen the screws 11–11, after which the adjusting screw 8 may be turned in a direction to advance or retract the frog to the desired extent. When the proper adjustment has been attained, the set-screws 11–11 are advanced by a screw-driver entered from the rear, until the heads of the screws 10a draw down on the frog and clamp it firmly to the saddle.

During the period of adjustment, the rib serves to guide the forward edge of the frog to and fro in exactly the proper line, thus relieving all the other parts of this burden. While of course an approximate alinement might be given by the cheek-pieces, it would require an expensive machining operation to so finish the cheek pieces and frog sides that accurate alinement, from this source, could be relied upon. By my invention the rib 7 may be cast integrally with the saddle and the groove in the lower side of the frog which rides on the rib may be quickly and easily formed so as to guarantee the maximum of perfection in adjustment at a minimum of expense and labor.

In the modification shown in Figs. 6 and 9, I provide the solid clamping stud 10b in place of the companion parts 10–10a, and in this case, instead of providing a tubular sleeve similar to 10, I provide a solid shank for the stud 10b.

I am aware that various modifications may be made, and, so long as the construction selected provides for adjustment of the frog without removing the plane-iron therefrom, I deem such modification as within the scope of the broadest of the claims herein.

What I claim is:

1. In a plane, a body portion having a sole and a throat therein, a frog support arranged at the rear of said throat and extending transversely across the sole, a frog mounted on said support, and adjustable to and fro, means for adjusting said frog comprising a screw accessible at the rear of said frog, means to secure said frog on said support comprising a clamping device projecting downwardly through the frog and into said support, a locking device comprising a screw entering said support from the rear, the forward end of said screw having a cone head, a recess in said clamping device into which said cone head may be projected, the inclined wall of said cone head engaging and forcing said clamping device in a direction to rigidly secure said frog in place.

2. In a plane, a body portion having a sole and a throat therein, a frog support arranged at the rear of said throat and extending transversely across the sole, a frog mounted on said support and adjustable to and fro, means for adjusting said frog comprising a screw accessible at the rear of said frog, means to secure said frog on said support comprising a two part clamping device projecting downwardly through the frog and into said support, a locking device comprising a screw entering said support from the rear, the forward end of said screw having a cone head, a recess in said clamping device into which said cone head may be projected, the inclined wall of said cone head engaging and forcing said clamping device in a direction to rigidly secure said frog in place, said clamping device being adjustable as to length.

To all whom it may concern:

Be it known that we, CHARLES E. MICHELL and EDMUND A. SCHADE, citizens of the United States, residing at New York, N. Y., and New Britain, Connecticut, respectively, have invented certain new and useful Improvements in Planes, of which the following is a full, clear, and exact description.

Our invention relates to improvements in the construction of planes, and particularly to the parts which are adapted to carry and provide adjustment for plane irons in that class known as bench planes.

The part of the plane which immediately supports the cutting tool or plane iron is commonly termed a frog. This part is so constructed as to bear upon and be supported by the stock portion of the plane and to itself carry and provide means for adjusting the position of the iron. This frog is commonly constructed of cast iron and separate from the base or stock portion of the plane. Frogs constructed in this manner of cast metal are heavy, and having the usual characteristics of such metal, are easily broken and but poorly adapted to withstand the strains to which such a structure is subjected. The great weight is also a material element in considering the usefulness and general utility of a plane. For this reason, it is desirable that the parts shall he made as light as possible and consistent with a requisite strength. In casting such a body as this, it is not feasible to make it of such a finish as to be immediately useful in the final construction which is desired. For this reason it is necessary that it should be put through several finishing operations under machine tools in which the surfaces are given the proper angles relatively to one another and finished to present satisfactory bearing surfaces and appearance. Being of irregular and peculiar shape, there are moreover set up in a frog strains due to the unequal cooling of the metal in different parts of the frog consequent upon the casting operation. These strains are likely to and often do cause checks and irregularities in the structure to such a degree that the parts are the more easily subject to fracture when used in the ordinary course of business. Even if actual defects do not appear on the surface of the metal, there sometimes are such initial strains in the interior as to seriously impair the strength of the parts. For these reasons and in order to make the structure in a more simple and economical manner we have constructed the parts of sheet metal which may he for instance cold rolled steel. ln this way a very light, reliable and economical structure is effected which in its use is most satisfactory and durable.

ln the drawings: Figure 1 is a side elevation partly in section of a plane embodying the improvements of our invention. 2 is a perspective view from the rear of the parts which immediately support a plane iron. Fig. 3 is a rear elevation of the same with what may be termed yoke portion of Fig. 4. Fig. 4 is a perspective view from the front of this so-called yoke portion. Fig. 5 is a view partly in section of the Y-adjustment lever which is used with the part of Fig. 2. Fig. 6 is a side elevation and section of the plane iron supporting member and adjusting devices.

In Fig. I the stock or base portion of the plane is represented as shown at 1 which may have as usual a rear handle and a forward knob for convenience in handling the same. In the base of the stock portion is provided the usual throat or opening 10, and to the rear a chair or seat 13. Above the chair is supported the part 2 which may he herein termed the frog and which provides the immiediate support or bearing for a plane iron. Beneath this frog is what may be conveniently termed a yoke portion 3 which may he attached to the frog as hereinafter set forth. The plane iron 4 which rests upon the face of the frog is in the form shown provided with a plate 5 at its upper surface. These are in turn held in place by a cap iron 6 and are provided with the Y-adjustment lever 7 coacting with an adjusting nut 8. A laterally adjusting lever 9 is secured at the top of the frog.

The yoke portion 3 which is formed at the lease in a manner suitable to cooperate with the chair portion 13 of the stock 1, is provided with slots or holes 30. Through these holes pass the screws 31 which secure the yoke portion to the base and thus provide a forward and backward adjustment for the position of the frog. The front end 32 of the base portion of the yoke may be bent downward at an angle to correspond with the under surface of the face of the frog to which it may be secured, as for example by rivets. The upright portion or back of the yoke extends upward and is secured at the downwardly bent portion 36 to the frog at a point just above the opening 20 in the face of the frog. Through this opening access may be had readily to the securing screws 31 in the base.

When the plane iron and plate are adjusted in position and secured to the frog by means of the cap iron 6 and cap screw 61, the frog is subjected to stresses of considerable amounts. To provide for meeting these stresses it is desirable that the sides of the frog should be bent down and depressed to form reinforcing flanges. It will be noted that these flanges as shown are substantially triangular in form and correspond in depth from the face of the frog very closely to the diagram of changes in bending moments which would occur in a beam loaded in the center and supported at the ends, which is the case that we have herein. The cap iron 6 is provided with a cam lever 65 for effecting the requisite pressure between the cap and the plane iron or the plane iron plate for holding the parts in place.

The upper end of the bearing face of the frog is depressed in a truss-like form at 29 to provide a recess in which the lower end of the aterally adjusting lever 9 may be pivoted at 92 and operate. The end of this lever 9 may be provided as is usual in planes of this character with a disk 94 which cooperates with a slot 40 in the plane iron 4 to effect the desired lateral adjustment. The depth of the cutting edge of the instrument may be adjusted by means of what is known as a Y-adjustment 7 in which the nose 75 projects forward through an opening in the face of the frog into a hole 50 in the plate which is above the plane iron. The plane-iron and plate being secured together by the screw 45, movement up and down of the Y-adjustment will also operate the plane iron itself.

The face of the frog is provided with a perforation or recess to receive the head of the securing screw which is thus let into the platform and allows the plane iron to have a smooth and even bearing upon the face of the frog. Above this recess the metal of the frog may be cut out and bent back in the form of ears 27 which will provide bearings for the pivot of the Y-adjustment. In order that these ears may be bent back at convenient angles and with as little injury to the metal as possible, it is desirable that the sides of the recess should be cut back both above and below the ears and at the base thereof as shown particularly in Fig. 3. ln order that the Y adjustment 7 may have a secure and even bearing and also to increase the economy and efficiency of the device, we have made the Y-adjusting lever 7 of sheet metal as shown in Fig. 5, in which 70, 70 are perforations in the two opposite sides of the lever to provide for the pivot pin. It will thus be seen that the lever has two bearings and that they are spaced apart a considerable distance. The lower ends of the arms 78 coact with the adjusting nut 8 which operates on the screw 81. in this construction as shown particularly in Fig. 6 the adjusting screw 81 is conveniently seated in the back of the yoke at a point near the top thereof where the strength and rigidity of the same would be sufficient to give it a secure bearing. lt is also desirable that the face of the frog should have a reinforcing piece at the point where the cap screw 61 is attached thereto. The bent down portion 36 of the yoke provides this in a most satisfactory manner. By this structure also the cap screw tends to aid in holding the yoke and the frog more securely together. The upper portion 33 of the back of the yoke may be out away as appears most clearly in Fig. 3, and thus provide an easy and convenient access for the purpose if desired of riveting the plate 36 to the frog 2. The lower front end of the yoke acts also as a reinforcement to the lower front edge or toe of the frog in the structure herein shown, and materially adds to the strength and efficiency of the parts since the pressure of the lower end of the cap iron 6 is applied near this point. The cutting edge of the plane iron may be projected through the throat or slot 10 in the base of the stock portion just in front of the toe of the frog. The face of the frog is also reinforced as shown by the depressed portion 29 which in stamping the article forms a corrugation at that point substantially opposite the point of application of the pressure applied by the cam lever 65 at the upper end of the cap iron.

The whole structure is exceedingly light in weight and although very simple and economical in its construction is durable and efficient.

The yoke 3 forms a backing for the plane-iron and may be referred to in some of the claims by the term backing or frog backing.

To all whom it may concern:

Be it known that I, CHARLES B. STANLEY, a citizen of the United States, residing at New Britain, county of Hartford, State of Comecticut, have invented certain new and useful Improvements in Handle Construction for Planes and other Tools, of which the following is a full, clear, and exact description.

My invention relates to a new and improved tool handle particularly adapted to planes.

The object of the invention is to provide a superior construction by which a strong and durable handle may be formed from composition which would otherwise lack sufficient strength in itself to resist hard usage. Ordinarily this material is molded from some suitalble composition, and it has been found that by reason of the fragile character of most compositions there is great loss due to breakage, not only occurring when the handles are applied to the planes, but also in after use. By my invention the strain of the holding devices is effectively resisted, the molded or pressed composition of the handle being relieved of the same.

In the accompanying drawings Figure 1 is a vertical section of a plane handle constructed to embody my invention, a portion of the same being shown in side elevation. Fig. 2 is an edge view of reinforcing means detached from the handle. Fig. 3 illustrates the same part and the reverse side from that shown in Fig. 1. Fig. 4 is a section on line x–x of Fig. 3, looking down. Fig. 5 is a view of the under side of the same part.

In the drawings, 1 represents the grip portion of the handle, which may be of conventional form, said grip portion being made of a suitable composition material molded or pressed to the desired configuration. Arranged within the handle is a reinforcement of iron, or other suitable material, capable of withstanding severe strains and hard usage. This reinforcement is preferably of skeleton form and is so arranged as to furnish a backbone for the handle at all vulnerable points, and at the same time is available to receive the screw fastenings (not shown), by which said handles are secured to the plane bodies. This reinforcement comprises the base plate 2, preferably provided with the feet 3–3a, the ends of which feet are coincident with the bottom surface of the finished handle so as to act as a support. The plate 2 has an upwardly extending fin 4, which extends through the grip portion 1 of the handle and well toward the upper end thereof, as best seen in Fig. 1.

5 is an upper bearing for one of the fastening screws (not shown). 6 is a lower bearing for the same screw. The upper bearing 5 is coincident with the upper end of the grip portion of the handle, so that the strain of the screw head when in place will be taken directly by the bearing 5, then by the web 4, then by plate 2, and finally by the bearing 6 and foot 3. 7 is another bearing for another fastening screw, the upper end of this bearing being exposed at the upper surface of a forwardly extending portion 1b at the base of the grip 1. This bearing 7 likewise takes the strain of the head of the second screw, which passes therethrough when the handle is applied.

The web 4, in order to insure lightness may be out away, as at 8–8a, the cut-away portion so being between the bearings 5–6. The two sides of the web adjacent the cut-away portion 8a may have offset connections 9–9 to properly tie together the two parts of the web, said connections being offset to afford clearance passage for the screw. These openings 8–8a permit the composition material to become more rigidly anchored to the reinforcement.

From the foregoing it will be seen that a handle thus constructed possesses very great strength and durability, and the danger of breakage is reduced to a minimum. It will be also seen that the strain of the holding screws is taken wholly by such parts and material as are best capable of withstanding the same. It will also be seen that the composition covering or envelop may be made from a material that would otherwise be unavailable because of too little initial strength, such, for example, as cork. These and other advantages will be apparent to the experienced mechanic.

What I claim is:

1. In a tool handle, a grip of composition material, an interior reinforcement having a screw passage therethrough from end to end of the grip portion of said handle, said reinforcement carrying a bearing at the upper and lower end to receive a fastening screw.

2. In a tool handle, a grip of composition material, an interior reinforcement having a screw passage therethrough from end to end of the grip portion of said handle, said reinforcement having a bearing at each end to receive a fastening screw, and having a second screw passage, and a bearing for a second fastening screw, both of said bearings relieving the composition covering of said reinforcernent from the strain of fastening screws.

3. A tool handle formed of composition material and having an inclosed metallic reinforcement, said reinforcernent having two screw passages therein and having bearings at the base of the reinforcement adjacent to said screw passages, and other bearings at the upper end of both screw passages arranged to directly receive the strain of fastening screws.

The object of the invention is to provide an improved combination of parts whereby composition and similar handles may be constructed in such a way as to effectively withstand the strain which comes upon the fastening screw at the forward portion of the handle, thereby removing the danger of breakage, which has been found to be in this class of handles, very great.

In the manufacture of what are known as imitation rubber handles, the composition material employed is of a fibrous or brittle nature, and it frequently happens, owing to the shape of the handle, that the material through which the forward screw passes is unequal to the strain and that portion of the handle becomes broken.

With my invention I propose to overcome this defect and to provide the handle at its most vulnerable point with an effective reinforcing device which can be very economically produced, and in combination with the remainder of the handle, be used to great advantage.

In the accompanying drawings, — Figure 1 is a vertical section of a handle for a plane, the reinforcement therefor being shown in side elevation. Fig. 2 is a section on the line X–X Fig. 1. Fig. 3 is a side elevation of the reinforcement, detached. Fig. 4 is a plan view thereof. Fig. 5 is a view of the under side thereof.

1 represents the body or grip portion of the composition plane handle, usually made from fibrous material of considerable brittleness, molded to the desired shape. The handle is usually screwed to the upper side of the sole of the plane (not shown) by means of suitable fastening devices passing through the apertures 2 and 3. Inasmuch as the aperture 3 is located in a comparatively thin part of the extended base 1a of the handle, the pressure employed in screwing the handle in place is frequently such as to break the handle. Then, too, the strain which comes upon the forward end of the handle, when held by the operator, is very great, owing to the weight of the plane, which is largely borne by that end. Also, the inclination of the large screw which enters the aperture 2 is such as to cause the handle to be forced backward in attaching it to the plane, thereby creating what is known as the drag of the screw. This drag of the screw causes the handle to move backward relatively to the plane sole, to which it is attached, and when the material is fibrous or brittle, causes the material to be broken adjacent to the forward screw. To overcome this defect I provide metallic means for reinforcing the lower part of the handle, taking the strain of the screws and relieving the handle from all tendency to breakage, the reinforcing means in the particular form shown herein comprising the plate 4, having the feet 5–6.

7 is a hub extending upward from the plate 4 and directly over the circular part of the foot 6. The screw hole, or passage 3, extends through the hub 7 and the foot 6. The screw passage 2, extends through the rear end of the plate 4, preferably closely adjacent to the foot 5, which, in this particular instance, is located just forward of said screw passage.

8 is a reinforcing web formed on the upper side of plate A to prevent the buckling or breaking of the base plate and to establish in general a secure and operative connection between the base plate and the remainder of the handle.

It should be understood that although the feet 5 and 6 perform a useful function, their use is preferable rather than essential, as the base plate 4 would in large measure discharge the duties required of it if the feet were removed and it rested directly upon the upper side of the sole of the plane.

It should be understood also that the shape of the reinforcing web where it extends up into the gripping portion of the handle, is not material. The height to which it extends, and the shape which it takes in the portion of the handle which is grasped by the hand, is a matter which may be greatly varied without departing from the spirit or true character of my invention.

In operation it will be seen that the strain which in use is occasioned by the screw passing through the passage 2, is taken by the portion of the metallic plate surrounding the screw, so that all danger of breaking off the handle at its base is avoided. Likewise, the strain, which, but for the metallic reinforcement, would come upon the extended front end of the handle when in use, is prevented from breaking the handle or doing damage in any way.

It will be understood that the head of the screw which extends through the passage 3, sets down upon the metallic hub 7 and that the pressure of the screw is transinitted directly downward to the base of the plane, the connection between the underside of the screw head and the sole of the plane being metallic all the way.

The strain occasioned by the drag upon the screw, inserted through the passage is taken by the metal surrounding the passage, thereby reducing all danger of breakage to a minimum.

The material of the handle being usually molded into shape permits the plate 4 and the parts connected therewith to be located within and hidden by the material of the handle, the only exposed parts being in the preferred form — the feet 5 and 6 and the upper end of the hub 7, which latter, when the screw is in place in the passage 3, is covered by the head thereof. By this means the strain of the holding screws is wholly taken up by the metallic portion of the plane handle, and the plane handle as a whole becomes as effectively provided with means for resisting tendencies to breakage as if it were not composed of a composition or other brittle material.

It should be stated that this invention is not confined to imitation rubber handles but extends to other handles produced by shaping in a mold and reinforced in the manner herein described.

It should also be understood that it is immaterial whether the reinforcing plate and its subordinate parts are composed of a single piece of cast metal or are made in separate parts and united together in any well understood mechanical manner.

What I claim is:

1. In a composition handle of the character described, a grip portion and a base portion, a plate reinforcement for said base embedded therein, said base having a screw passage extending through said plate, said reinforcement being arranged to take the strain of the screw and distribute the same along the base to relieve the material of the handle from said strain.

2. In a tool handle, a composition body molded to the form of the handle and comprising a grip portion and a base portion, a plate reinforcement for said base, said plate being embedded therein and having a foot projecting downwardly and terminating coincident with the lower bearing surface of the base portion, a screw passage adjacent to said foot, said reinforcement being arranged to take the strain of the screw to relieve the material of the handle from said strain.

3. In a composition tool handle of the character described, a base, a plate-like reinforcement embedded therein, a web reinforcement for said plate, said web being formed integrally therewith.

4. In a composition handle of the character described, a grip portion and a base portion, a metallic plate reinforcement for said base, two screw passages through said handle and plate, portions of said plate being arranged coincident with the lower surface of the base of the handle.

5. In a tool handle of the character described, a grip portion, a base extending forwardly from the lower end of said grip portion, a plate reinforcement for said base and having two screw passages, one coincident with the grip portion, and the other coincident with the forwardly extending base portion, a part of said plate being coincident with the lower surface of the base.

6. In a tool handle of the character described a grip portion, a base extending forwardly from the lower end of said grip portion, a plate reinforcement for said base and having two screw passages, one coincident with the grip portion, and the other coincident with the forwardly extending base portion, a part of said plate being coincident with the lower surface of the base, a hub on the plate surrounding the screw passage coincident with the forward rear extension of the base and arranged to directly receive the strain of the screw.

To all whom it may concern:

Be it known that I, JOHN L. PRINGLE, a subject of the King of Great Britain, and residing at New Britain, in the county of Hartford and State of Connecticut, have invented a new and Improved Plane, of which the following is a specification.

My improvement relates to the class of hand tools used for working upon the surface of boards and the like for smoothing or for grooving, or for similar purposes, and the object of my invention is to provide a plane which shall be simple and cheap in construction, few as to the number of parts, and one which may be put to all of the varied uses to which this class of devices are subjected.

One form of device in the use of which the desired object may be attained is illustrated in the accompanying drawings, in which —

Figure 1 is a perspective view illustrating the bottom and one side of a plane embodying my invention. Fig. 2 is a like view looking from the opposite side of the plane. Fig. 3 is an end view showing the bottom gage-sole used as a side gage. Fig. 4 is what may be termed an illustrative view showing the application of my improvement in cutting a tongue on the edge of a board. Fig. 5 is a like view showing the improvement adapted to the formation of a molding. Fig. 6 is a like view showing the improved tool adapted to cut a groove in the edge of a board. Fig. 7 is a like view showing the improved tool as applied to cutting a concaved surface. Fig. 8 is a view illustrating a modified form of the adjustable gage-sole.

In the accompanying drawings the letter a denotes the body or stock of tlie plane, b a knob or handheld at the forward end, and c a handle located at or near the rear end and on the upper surface of the body part in the usual manner. The body part may be constructed of wood or of any other desired material common to tools of this class. The body part is also provided with a depthwise opening d in which the blade or bit e is located. All of these parts may be of any ordinary and well-known construction.

In carrying out my invention I provide a vertically adjustable secondary sole 1 secured preferably to the side part of the body of the plane, and a laterally adjustable gage-sole 2 which is located underneath the body. The sole 1 includes a plate extendin lengthwise of the body part of the plane, this plate being of proper width and thickness for the purposes in hand, and as shown herein, and as ears 4–5 projecting from the upper edge thereof. These ears are provided with slots 6 through which adjusting studs or screws 7 extend for the purpose of holding the plate in any position of vertical adjustment. An opening 8 is also formed through the ear 5 through which cutting tools or blades of various form may project.

The gage-sole 2 has slots 9 extending laterally thereof formed therein, and studs or screws 10 projecting through these slots into the body of the plane serve as a means of securing the shoe in any position of lateral adjustment. The heads of the screws 10 are located well within the slots, the latter being shouldered to receive the head of the screw. These slots 9 are located at equal distances from the ends of the sole so that the latter may be reversed end for end for certain purposes to be hereinafter described.

It will be seen from the above description and the accompanying illustration that by removing the soles 1 and 2 the plane may be used for all the purposes of a smoothing plane or other surfaces. By placing the secondary sole 1 in position and providing the proper cutting blade the plane may serve the purpose of a plow. By placing the gage-sole 2 and adjusting it in proper position laterally on the bottom of the body part with a proper shaped blade in position, the plane may be used to out moldings of different form. By properly adjusting the soles 1 and 2 with respect to each other and using a blade of proper form articles may be formed of curved shape or round.

The gage-sole 2 is provided on one edge with a recess 14 the walls of which are located preferably at right-angles to each other. When this groove is employed what may be termed the horizontally arranged wall 15 will serve as the bottom proper or sole of the plane, in connection, of course, with the secondary sole 1, and the side or vertically arranged wall 16 will form a gage.

The gage-sole 2 is provided with blade recesses 17 and 18. These recesses are formed to receive one side of the blade of a bit when the tool is used for certain purposes. As shown in Fig. 2, the recess 17 covers one side of the cutting edge of a comparatively wide bit, so that the pidane with such bit may be used as a fillister plane.

By adjusting the gage-sole 2 vertically and laterally, as shown in Fig. 5 of the drawings, and also by adjusting the second ary sole 1 it will be seen that the plane is readily adapted for cutting various forms of moldings, the blade 18 being, of course, properly adjusted.

By adjusting the parts as shown in Fig. 4 the device is adapted for cutting a tongue on the edge of a board, the bit 19 having one of the prongs lying within the opening 8 in the vertical guide, and the other prong extending through the shoulder 15, the edges of these being shown projecting as at 20 in Fig. 4. By reversing the gage-sole 2 and moving it to the position shown in Fig. 6 the device may be used for cutting a groove on the edge of a board, the same knife as shown in Fig. 4 being employed, and that point located within the opening in the secondary sole 1 cutting the groove and the other point being located within the recess 18 in the sole 2, as shown in dotted outline in Fig. 6.

If a circular or curved recess is to be reduced then a blade 21, as shown in Fig. 7 of the drawings, may be used, having its cutting edge of proper form, the extreme curved edge of the blade being located just in advance of the sole 1, and the sole 2 being emlployed as a guide.

In order to adapt the sole 2 for vertical adjustment adjusting supports are mounted on the arms 11, these consisting of a sleeve 22 having set screws 23 with wings 24 bearing adjusting screws 25 which engage threaded sockets in the surface of the gage-sole 2. When the gage-sole 2 is used with the recess 14 facing the secondary sole 1, as shown in Figs. 1, 2, 4, and 5 of the drawings, the screws 10 may be turned out of the stock a or may be removed entirely. It is also obvious that when the gage-sole 2 is used as shown in Figs. 1 and 2, the adjusting screws 25 are not absolutely essential, a though they form a means of support for the projecting edge of the sole.

While the secondary sole 1 has been shown herein as adjustable it is obvious that advantageous results would follow its use in a plane in which it was rigidly secured to the stock without any means of adjustment, but by providing the adjustment I secure all of the advantages present in the late as used in either of the ways mentioned.

In the form of adjustable sole shown in Figs. 1 and 2 the gage-sole is reversed end for end when it is desired to employ the sole as a gage. In Fig. 8 I have adapted this form of the invention so that the sole need not be so reversed when it is to be employed as a gage. In this form of the invention I construct the gage-sole in two parts, a main section 26 and an adjustable section 27. The main section is rovided with a groove 29, and the adjustable section with a shouldered groove 30, a screw 28 to take the place of the screws 10 hereinbefore described for holding the parts in engagement and for holding the sole as a whole in place on the sole or bottom of the plane. It will be seen from this construction that with the parts adjusted as shown in Fig. 8 the device is applicable for the same use as shown in Figs. 1 and 2. By loosening the screw and moving the adjustable section 27 so that the edges are flush, then the sole is adapted for a gage, as illustrated in Fig. 3. It will be noted that the parts 1 and 2 act as soles for the plane, that is, they support the plane in a direction depthwise thereof, the secondary sole 1 supporting the plane when grooves, tongues and the like are being cut, and the gage-sole in connection with the secondary sole supporting the plane as when moldings, and rabbets are cut. It will be noted that when either of the soles 1 and 2 are employed the sole proper of the plane is not in use, the latter mainly being employed when the plane is used as an ordinary surface plane.

I claim:

1. A stock having a bit opening and adapted for use as a surface plane, a secondary sole secured to the side surface of said stock and adjustable depthwise to project below the main sole thereof, and a gage-sole underlying said main sole and adjustable laterally thereof, both of said secondary and gage-soles having openings for the bit and adapted to cooperate therewith in the cutting operation.

2. A stock having a bit opening and adapted for use as a surface plane, a secondary sole secured to the side surface of said stock and adjustable depthwise to project below the sole thereof, a age-sole underlying the main sole and lateragy adjustable thereof, and means for securing the latter sole directly to the under surface of the stock, both of said secondary and gage-soles having openings for a bit to cooperate therewith in the cutting operation.

3. A stock having a bit opening adapted for use as a surface plane, a secondar sole secured to the side surface of the stock and adjustable depthwise to project below the main sole thereof, a reversible gage-sole underlying the said main sole, means for securing said sole in position, both of said secondary and gage-soles having bit openings to cooperate with the bit in the cutting operation.

To all whom it may concern:

Be it known that I, JOHN H. SHAW, of the city and county of New Haven, State of Connecticut, have invented new and useful Improvements in Planes, of which the following is a full, clear, and exact description, when taken in connection with the accompanying drawings, which form a part thereof, and in which —

Figure 1 represents a side elevation of a plane embodying the invention, Fig. 2 an end view of the same, Fig. 3 a similar view with the handle shown adjusted to a different position, Fig. 4 a top view of the handle end of the plane, Fig. 5 a similar view with the handle removed, Fig. 6 a similar view with the supporting block removed, Fig. 7 a bottom view of the handle plate, and Fig. 8 a side elevation of the supporting block.

In all figures, similar letters of reference represent like parts.

This invention relates to planes, and has for its object the production of a simple and efiicient construction by which the handle may be adjusted so that the plane can be used close to a wall or other object without injury to the hand of the operator.

When a plane is used in proximity to an object, as a wall, it is diflicult to bring the plane close to the corner without interfering with the hand of the operator. To this end various methods have been devised by which the handle may be adjusted or turned to an angle other than a right angle to the bottom of the plane so as to remove the hand of the operator further from the side of the plane against the wall.

The present invention consists of a removable supporting block for the handle, which may be mounted on the ordinary plane body so that the handle may be adjusted or rotated on the supporting block to project at the desired angle, together with other improvements and combinations of parts hereinafter described and claimed.

For a better understanding of the invention reference is had to the accompanying drawings, in which the parts designated by the letter A represent the plane body and B the sides thereof. On the plane body, near the rear, is a usual base C for the handle, having a screw hole or holes D. When a handle is mounted on this base it assumes the ordinary position at right angles to the plane body, and is incapable of adjustment.

A supporting block E is therefore provided, which is herein shown fiat on its under side and convex transversely on its upper face (Figs. 2 and 3). The supporting block E is adapted to be secured to the plane body by a screw F, or other means, taking into one of the screw holes D.

The handle G is provided at its lower end with a plate H concaved transversely as shown, so that its under face is adapted to fit on the convex surface of the supporting block E. The plate is provided with one or more transverse slots K for the reception of screws L, which extend through the slots and take into screw holes M in the block E. The heads of the screws L or washers N, engaged thereby, bear on the plate H to bind in its adjusted position.

To shift the handle from one angle with the plane body to another it is only necessary to unscrew the screws L and the plate H will then be capable of sliding in either direction on the block E, so that the handle will assume either of the positions indicated in Figs. 2 or 3. When the screws L are tightened the handle is secured to its adjusted position. As the block E is removable the plane body may be used with an adjustable handle or with an ordinary handle as desired.

Having now described my invention, what I claim and desire to secure by Letters Patent is:

In a plane, the combination with the plane body; of a removable supporting block curved in cross section and adapted to be rigidly secured to the plane body; a correspondingly curved plate adapted to fit on said supporting block; a handle secured to said plate; slots in said plate; and screws projecting through said slots and engaging said block to hold said plate and handle in their adjusted position, substantially as described.

In witness whereof, I have hereunto set my hand on the 4th day of August, 1905.

To all whom it may concern:

Be it known that I, JUSTUS A. TRAUT, a citizen of the United States, residing at New Britain, Hartford county, Connecticut, have invented certain new and useful Improvements in Scrapers, of which the following is a full, clear, and exact description.

My invention relates to improvements in scrapers.

The object is to facilitate adjustment of the parts and improve the construction so that it may be adapted to use under many different circumstances. I have sought to construct the parts so that they may be manufactured readily and assembled or taken apart without difficulty.

The preferred form of the invention is shown in the accompanying single sheet of drawings, in which —

Figure 1 is a side view of the scraper embodying the improvements of my invention. Fig. 2 is a front view of the same. Fig. 3 is a rear view of the scraper with the handle shown in section. Fig. 4 is a rear view of the back member of the head. Fig. 5 is a side view of the same. Fig. 6 is a plar view of a fragment of the handle.

The handle is preferably formed in two portions — a grip member 1 and a body member 2.

The head of the scraper carries the blade 3 and is preferably provided with an auxiliary grip or handle 4.

5 and 6 are the front and rear members, respectively, of the head, between which the blade is clamped.

7 is a screw located between the upper and lower ends of the plates 5 6. This screw passes freely through plate 5 and takes into plate 6, so as to produce, in effect, a hinged joint which may be adjusted to and fro to vary the widths of the space between plates 5 6.

8 8 are screws arranged at opposite edges of the plate 6 and screw-threaded therein. The ends of these screws project into cavities in the opposite face of the member 5, but are not screw-threaded therein. The function of these screws is to preserve the alinement of plates 5 6 and to act as spacers to guarantee the substantial parallehsm of said plate, whereby the ready substitution of blades 3 is permitted. The screws 8 8 also perform a stop function, the upper edge of the blade 3 taking a bearing against said screws so that blade will be projected uniformly from the clamping-jaws. These “stop-screws” 8 8, as we shall term them, may be shifted up or down on plate 6, there being a series of screw-holes a ong opposite edges thereof to permit this shifting of the screws to be made. By this means when blade 3 wears down or if a short blade is to be substituted the screws 8 8 may be moved to any one of the holes 8’, 82, or 83, so as to adapt the holder to the particular blade to be used.

9 is a main adjusting-screw having a stop-head whereby it may be easily operated. When approximate adjustment of the plates 5 6 has been secured by the adjustment of screws 7 and 8 and the blade inserted, the user may set up on screw 9 in such a manner as to powerfu ly clamp the blade 3. The rear of the back member 6 of the head is provided with a pair of lugs 10 10, to which the handle is pivoted.

11 is a curved arm extending from the rear of the back member and provided with a curved slot. This arm is preferably formed pf a separate piece of metal and riveted to the lug 12.

13 is a screw preferably provided with an enlarged head for engagement by the thumb and finger and by means of whic the handle is clamped to the arm 11. By this means the angle which the blade makes relative to the handle may be readily varied to suit the conditions under which the scraper is to be used. The parts, however, when clamped together are rigid, so that there is practically no vibration possible when the tool is in use.

What I claim is —

A scraper comprising a head portion formed of two parts, means for adjustably connecting the same at an intermediate point, said connection permitting said parts to swing, jaws formed by the edges of said parts at one slde of said connection, a clamp-screw at the opposite side of said connection, said clampmg-screw passing through one part and bearing against the other, and adjustable stop-screws at the opposite slde edges of said parts, and a handle hinged to one of said parts and means for adjusting the angle of said handle relatively thereto.

To all whom it may concern:

Be it known that I, JUSTUS A. TRAUT, a citizen of the United States, residing at New Britain, Hartford county, Connecticut, have invented certain new and useful Improvements in Scraping-Tools, of which the following is a full, cllear, and exact description.

My invention relates to improvements in woodworking-tools; and it consists in an improved scraper, the construction of which is such that it may be used, if desired, with an ordinary plane, merely substituting the same for the usual plane-iron. In this connection the device is capable of all of the adjustments to which the usual plane-iron is adapted and may be employed with an unusual degree of success.

In the accompanying drawings, Figure 1 is a longitudinal section of an ordinary plane-body fitted with my improved scraper. Fig. 2 is a perspective view of the scraper and scraper frame or carrier. Fig. 3 is a plan view of the same. Fig. 4. is a detail view of a clamping member.

I will first describe the scraper and scraper-carrier.

A is the scraper-blade, having the usual sharpened edge.

B B’ are two arms of the frame or scraper-carrier arranged to carry the blade A. As shown, these arms B B’ are arranged in the form of a wedge or a V — that is, the outer bearing-surfaces of the same form a V. The plane-iron A is clamped against the outer bearing-surface of the arm B by means of any suitabie clamping device — for example, the member C, carrying the clamping-screw C’. The arm B’ is so constructed and arranged that it may be readily applied to the plane-iron support or “frog” of a plane, the connection being preferably such that the various adjusting devices commonly found on planes will be available for the purpose of adjusting the position of the cutting edge of the scraper-blade in the throat of the plane. In the drawings, Fig. 1, I have shown the scraper-frame as it would appear in place on an ordinary plane. In this view, D indicates the main body of the plane. E E’ are the handles. F is the usual frog on the plane-iron support. G is the usual clamping- plate cooperating with the screw-post J. H I are adjusting-levers such as commonly employed in planes and by which the plane-iron may be given any desired adjustment. These levers need not be explained in detail, since their operation is well understood.

On referring to Fig. 1 it will be seen that the scraper-frame is clamped to the frog precisely as the ordinary plane-iron is clamped thereon, and the edge of the scraper-blade A will project through the throat or passage in the sole of the plane in the same manner as will the edge of the plane-iron, excepting that it will stand at a substantially different angle. The arm B of the scraper-frame is cut back or recessed transversely near its lower end, as indicated at K, to give a clearance back of the cutting edge of the scraper-blade. This is done to permit the cutting edge of the scraper to yield slightly and is productive of the most effective results in operation. While the scraper-frame is primarily adapted for use in connection with the plane, nevertheless the frame or carrier will itself afford a convenient grip when the scraper is used independently of a plane-body. The angle of the bearing-surfaces of the arms B B’ (indicated in the drawings) is that best adapted for the most successful results when the scraper is to be used in connection with the plane; but this angle, of course, may be varied to some extent at will. In the arm B’ of the scraper-frame a central longitudinal passage B2 adords clearance for the post J.

L is the usual cam by which the clamping-plate G may be set down hard, so as to hold the scraper-frame firmly on its seat.
