To all whom it may concern:

Be it known that We, ALIX W. STANLEY and EDMUND A. SCHADE, citizens of the United States, residing at New Britain, in the 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.

This invention relates to planes, and particularly to improvements in the construction of that class of planes adapted to be used on curved surfaces, sometimes called “circular planes.” In planes of this character the base or sole is made flexible, so that it may be bent to any desired curve to cause the plane to fit onto a curved surface, either concave or convex. The sole portion of the plane is usually made of sheet metal, such as spring-steel. It is highly desirable in planes of this character that means be provided whereby the adjustment of the sole to the desired curve may be effected accurately and quickly. To that end, therefore, the main object of this invention is to provide simple and effective mechanism for attaining these results.

In the accompanying drawings, Figure 1 is a side elevation illustrative of a specific embodiment of my invention, the sole of the plane being curved to fit to a concave surface. Fig. 2 is a fragmentary perspective view of detached details of construction.

1 is the main body portion.

2 is the base or sole portion. The sole portion 2 is capable of being curved relatively to the main body portion 1. In the form shown the portion 1 is connected to the middle portion of the sole 2.

3 is the frog, carried by the frame 1 and in turn supporting the plane-iron 4. and the adjustments therefor. It is not necessary to explain in detail the adjustments for the plane-iron, because they are well known and constitute no part of this invention.

5 is a screw-threaded post mounted in a suitable screw-threaded bearing on the forward part of the body 1.

6 is a knob or handle carried by the post 5. When said post is rotated it will move up and down relatively to the body 1.

7 is a telescopic extension of the post 5. The connection between the post 5 and its extension 7 is screw-threaded. The screw-threads on the post which take into the frame 1 are right-hand threads, while the screw-threads on the extension 7 which take into the post are left-hand threads, or vice versa. The post extension 7 is connected to a lever 8 by means of a link 9. The lever 8 is pivotally mounted in the body 1. The link 9 prevents the extension 7 from rotating. The particular screw-threaded adjustment of the post 5 relatively to the frame 1 and the extension 7 relatively to the post 5 produces double the movement of the lower end of the extension 7 that would be produced were the link 7 merely projected into the post 5 without being oppositely screw-threaded. The lever 8 is connected with one end of the sole 2 by means of the link 11. 10 is another lever pivotally mounted in the body 1 and connected to the opposite end of the sole 2 by the link. 12.

15 is a pivot for the lever 8.

16 is a pivot for the lever 10. 13 14 are segmental gears fixed on the pivots 15 16, respectively, so that the movement of one of said levers will be transmitted to the other — for example, the movement of the lever 8 by the aforesaid means will produce a corresponding movement in the lever 10. Hence as the lever 8 is moved upwardly the sole 2 will be curved upwardly. If the lever 8 is moved downwardly, the sole 2 will be curved downwardly, and the position of the levers 8 and 10 and the degree and direction of curvature of the sole 2 are deterininable solely by the handle 6. By means of a suitable indicating device it may be ascertained whether the sole is flat or curved and if curved what degree of curvature exists in the sole. In the particular form shown the indicating device comprises a pointer 17, carried by one of the parts — for example, the body 1 — in such a position as to project into the path of movement of certain graduations carried by another part — for example, the segmental gear 13. Referring to Fig. 1, it will be seen that the pointer 17 projects into a curved slot in the segmental gear 13, adjacent to which curved slot there are certain graduations from zero upward and downward. These graduations indicate degrees of curvature in the sole. When the zero-mark on the graduated scale lies opposite the pointer or line of reading, it indicates that there is no curve in the sole. If any one of the graduations above the zero-mark is brought into line with the pointer, it indicates to the user that the sole is curved upwardly to a certain definite degree. The reverse is true of the graduations below the zero-mark. It might be said that the segmental gear 13 constitutes a movable pointer, which enables the user to accurately set the plane so that the sole will be curved to any desired degree to fit to any particular curved surface, and this adjustment may be accurately and quickly effected without any preliminary trials, such as fitting the plane to the particular curved surface upon which it is desired to operate. When the plane has been set as desired, a set-screw 18 may be operated to clamp the adjusting screw or post 5 and prevent accidental displacement. The set-screw 18 may operate to clamp a split collar on the frame 1, through which the adjusting-post 5 passes.

The subject-matter disclosed and claimed herein is a specific embodiment of the invention broadly claimed in Alix W. Stanley’s application for United States Letters Patent, Serial No. 142,844, filed February 14, 1903.

What is claimed is —

1. A plane for cutting curved surfaces comprising a body portion, a sole portion secured thereto, adjusting-arms pivotally secured to the body portion and connected to the sole portion, segments of gears carried by the pivotal supports, an index or scale carried by one of said segments, and a stationary indicator or pointer carried by the body portion of the plane coacting with the scale or index whereby the degree of curvature of the sole portion may be indicated.

2. A plane comprising a body portion, a flexible sole portion secured thereto, a pair of arms pivoted in said body portion and connected to the ends of the sole portion, an index or scale carried by one of said arms, and a relatively stationary indicating member carried by the body portion of the plane and coacting with the scale or index for indicating the degree of curvature.

3. A plane for cutting curved surfaces comprising a body portion, a sole portion secured thereto, a pair of arms pivoted to the body portion and connected to the sole portion, gear-segments mounted to operate with said arms, one of said segments being slotted and having a scale or index adjacent the slotted portion, and an indicating member carried by the body portion of the plane cooperating with the scale or index for the purpose specified.

To all whom it may concern:

Be it known that I, ALIX W. STANLEY, a citizen of the United States, residing at New Britain, in the 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 class of planes adapted to be used on curved surfaces, sometimes termed “circular planes.” In planes of this character the base or sole portion is so arranged that it maybe made to assume different curvatures to cause the plane to properly fit to surfaces of different degrees of curvature upon which it is desired to operate the tool. These curvatures may be either concaved or convex. In the particular form shown the sole or base is made of flexible material, such as sheet metal or spring-steel. When adjusting the sole to the desired curvature, it is most desirable that said adjustment may be effected accurately and quickly.

To that end, therefore, the object of my invention is to provide simple, effective, and durable means whereby the plane may be so adjusted that exactly the proper curvature will be given to the sole without requiring the user to make any preliminary trials to ascertain whether the plane fits the curved surface on which it is to be used.

Figure 1 is a side elevation illustrative of one particular embodiment of my invention, the sole of the plane being curved to operate on a convex surface. Fig. 2 is a fragmentary plan view of the setting and reading mechanism. Fig. 3 is a perspective view of the scale.

A is a frame or main body, perfectly rigid.

B is a base or sole, which may be made of any flexible material, preferably spring sheet-steel.

C D are links located at the ends of the sole and in the particular form shown connected with the ends of the frame A.

E is a frog connected with the sole B and supporting the plane-iron F and the adjustments therefor, which latter need not be explained, because they constitute no part of this invention.

H is a post connected with the frog E. In the particular form shown the post H passes up through a portion of the body A, and on the post is mounted a screw-threaded adjusting device J in the form of a thumb-nut. This thumb-nut is rotatable in the body A, but is held against longitudinal movement. Hence when this thumb-nut is rotated the post H is moved up or down to produce a curvature of the sole B.

K is a screw by the rotation of which the thumb-nut J may set at any desired position to lock the adjusted parts against accidental displacement. In the form shown one side of the post H is flattened and upon said flattened surface is a graduated scale L. The graduations may, however, be formed upon the post itself. This scale runs from zero upward and downward, the graduations being proper to indicate to the user the exact curvature of the sole. These graduations are read on the line of the upper surface of the thumb-nut J, since that member is relatively stationary and its upper surface constitutes a convenient indicating-line. The zero-mark when registering with the indicating line means to the user that the sole is flat and not curved either upwardly or downwardly. If the thumb-nut J is so turned as to raise the post H, the graduation thereon adjacent the indicating-line indicates to the user the curvature of the sole. In Fig. 1 the zero-mark will be seen to be above the indicating-line. Hence the sole is curved upwardly, so that the plane may be used on a convex surface. Were the post depressed, so that some graduation above the zero-mark should lie adjacent to the indicating-line, it would show to the user that the sole is curved downwardly. The particular graduation would indicate to him the exact curvature of the sole.

The construction as a whole is simple and reliable and facilitates the accurate and quick adjustment of the sole to any definite curvature without the necessity of making any preliminary trials.

It is apparent that the plane herein specifically shown and described is capable of modification without departing from the spirit or scope of the invention.

Another specific embodiment of this broad invention is shown in a companion application, Serial No. 142,845, filed February 14, 1903.

What is claimed is —

1. A plane for operating on curved surfaces comprising a relatively stationary frame or body portion, a flexible sole portion secured thereto, an adjusting post or screw coacting with the flexible sole portion, and the relatively stationary body portion, a scale or index carried by the adjusting post or screw and a relatively stationary indicating member coacting with the post for the purpose of determining the change of curvature of the sole portion as indicated by the scale, said indicating member having a rotative movement relatively to said body.

2. A tool for planing curved surfaces comprising a relatively stationary body portion, a flexible sole portion carried thereby and movable relatively to the body portion, an adjustable scale-carrying member movable with the sole portion, and a relatively stationary indicating member carried by the body portion cooperating with the scale portion whereby the relative positions of the body and sole portions of the plane may be measured, said scale having graduations running upward and downward from zero.

3. A plane for curved surfaces comprising a body portion, a relatively movable and flexible sole portion pivotally mounted with respect thereto, an adjusting-screw operating in the body portion and cooperating with the sole portion, a scale or index carried by said screw, an adjusting-nut operating on said screw and in conjunction with the body portion, one edge of the adjusting-nut being adapted to act as a pointer or indicating member in conjunction with the scale for determining the relative positions of the body and sole portions.

To all whom it may concern:

Be it known that I, ALIX W. STANLEY, a citizen of the United States, residing at New Britain, in the 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.

This invention relates to planes.

The object of this invention is to provide a construction by which the support for the cutting-iron shall be such that the chattering of said iron in use is entirely prevented. In planes of this character the support for the cutting tool or iron is termed a “frog,” and the frog is commonly made in a piece separate from the body or stock of the plane. The reasons for this are several, among which is that an adjustability is permitted whereby the effective size of the opening or throat in the stock or base of the plane through which the cutting-iron works may be narrowed or widened, as desired, according to the character of the work. Another is that the frogs are provided with the adjusting device, and it is more convenient to equip said frogs with said adjusting devices when they are separate from the stocks than would be the case if they were integral with the same.

The accompanying drawings show the preferred form of the invention.

In said drawings, Figure 1 is a side elevation, partly in section, of a plane embodying my invention. Fig. 2 is a plan view of the base or stock portion of the plane with the frog, cutting-iron, and the associated parts removed. Fig. 3 is a similar view of a modification. Fig. 4 is a perspective view of a frog such as is adapted for use in connection with the stock shown in Figs. 1 and 2. Fig. 5 is a perspective view of a modified form of frog adapted for use in connection with the stock or frame shown in Fig. 3.

In the particular form shown, 1 is the floor or sole of the stock portion.

2 2 are side walls or flanges.

3 is a throat or slot in the bottom or floor 1 of the stock.

4 is a frog which is supported, preferably, on two seats or bearings. These seats may comprise an elevated chair 5 and a bearing 6 upon the floor 1. The bearing 6 is formed by thinning down the floor 1 directly to the rear of the throat 3. This thinning down may be effected in casting the stock, (for it is by the casting process that stocks are ordinarily made,) or it may be formed by machine-work after the casting is produced. The purpose of making the bearing 6 thin will hereinafter be explained.

7 7 are screw-passages in the frog, preferably elongated so as to permit the frog to be adjusted forward or back, thereby changing the position of the cutting edge of the plane-iron in the throat 3.

8 8 are clamp-screws (two are preferably used) by which the frog 4 is secured to the stock. The clamp-screws 8 are located between the elevated bearing 5 and the bearing 6 for the frog, so that when the screws are set down they will firmly clamp said frog against both of said bearings 5 and 6. In consequence of the fact that these bearings are spaced apart considerably when the parts are assembled it is impossible for the frog to chatter upon the stock. By loosening the screws 8 the frog may be moved backward or forward, as desired, to place the cutting edge of the plane-iron correctly relatively to the throat 3.

9 is the plane-iron, the lower edge of which is sharpened in the usual manner and is caused to project through the throat as desired. It is preferred that separate adjusting devices be provided to facilitate the longitudinal positioning of the plane-iron.

10 is a cap of the ordinary form carrying the cam 11, also of the ordinary form, and 12 is a cap-screw carried by the frog 4., which projects through a slot in the plane-iron 9 and engages the cap 10 in the usual manner, so that when the parts are assembled the plane-iron is clamped in proper position.

Manifestly the method of clamping the plane-iron to the frog may be varied as desired, since the particular device for accomplishing this end constitutes no part of this invention, excepting as it is obvious that the clamping means should take a long bearing upon the plane-iron to hold it in proper engagement throughout substantially the full bearing-surface of the frog 4.

Inasmuch as the frog is independent of the stock and inasmuch as the clamping effect of the screw 8 is considerable and inasmuch as the bottom 1 directly to the rear of the throat 3 is thin, the clamping effect of the screw 8 might tend to slightly bulge the said thin portion of the door, since this portion preferably affords one of the bearings for the frog. In order to prevent this bulging, I provide a supporting and stiffening rib 13, which in its preferred form is cast integral with the stock of the plane and preferably so as to extend from said thin portion to a heavier portion of the stock. Any desired number of these strengthening-ribs maybe provided. In Fig. 2 one of these ribs 13 is shown. In Fig. 3 two ribs 13 13 are provided; otherwise the construction is identical. I mention this, because it is obvious that the number of stiffening-ribs employed is immaterial. In order to permit the frog to take a proper bearing, I channel out the under side of the frog directly above the strengthening-ribs 13, so that the frog will not encounter the rib when the parts are assembled, but will take its proper bearing upon the seat 6. Manifestly this construction may be modified in a variety of ways.

In operation it is obvious that unless an efficient bearing is provided for the member or members which support the cutting-iron the passing of the plane over the material to be smoothed or cut might cause a vibration and a chattering of the parts. It is therefore desirable to have the forward bearing or point of contact which the plane-iron takes with the stock or parts associate therewith as close to the cutting edge as possible. Heretofore no special attention has been paid to thinning the metal of the stock directly to the rear of the throat. By thinning the metal at this point as I have done the frog supports the plane-iron almost down to its lower edge. In fact, when the best effect is produced the only unsupported portion is the beveled portion formed in shaping the edge. This will be seen in the section Fig. I. While this is of advantage generally, it is of particular advantage in that type of planes wherein the frog is adjustable longitudinally of the plane, so as to widen or narrow the throat, or rather that portion of the throat forward of the cutting edge of the plane-iron. By this invention in its preferred form a greater range of adjustability is rendered possible, since the frog may be moved to the rear of the throat to a considerable extent before the knife or cutting-iron will touch the metal of the stock. This is due to the fact that the metal of the stock may be made so thin at this point that the cutting-iron will not engage it, excepting at a point very close to its cutting edge. As a direct consequence the plane-iron may be adjusted forward or backward substantially the full width of the throat and still have an unimpaired and effective bearing directly upon the frog.

While I have shown and described a preferred form for the door of the stock to the rear of the throat, it is obvious that this may be modified in a variety of ways without departing from the spirit and scope of my invention, which in this respect relates to the provision of a suitable strengthening means adapted to reinforce the door immediately to the rear of the throat, so that that portion may be made thin, while the portion farther to the rear is of sufficient thickness to be self-supporting.

What I claim is —

1. In a plane, the combination with the stock, a frog, a plurality of bearings on said stock for said frog, and a clamping device located between said bearings, a slot or throat in the bottom or door of said stock portion, the bottom or door of said stock portion to the rear of said throat being thinned out up to the edge thereof, and means for strengthening said thinned-out floor.

2. In a plane, the combination with a stock having a plurality of seats for a detachable frog of a throat extending transversely of the stock and in the bottom thereof, the door of said stock directly to the rear of said throat being of thin metal, and strengthening-ribs extending from the heavy part of said stock to said thinned-out portion, substantially as described.

3. A stock for a plane having a transverse slot therein forming a throat for the passage of the plane-iron, the door to the rear of said throat being thin, the stock to the rear of said thin portion of the door being heavy, and a rib extending from said heavy portion to said thin portion, and strengthening and supporting the latter.

4. In a plane, a stock, a transverse slot therein forming a throat for the passage of the plane-iron, the door to the rear of said throat being thin, the stock to the rear of said thin portion of the door being heavy, and a plurality of ribs extending from said heavy portion to said thin portion, and strengthening and supporting the latter.

5. A plane having a stock portion provided with a throat, a frog, said stock portion being provided with two bearings for said frog, a rib connecting said two bearings, said frog being correspondingly grooved.

6. A plane having a stock portion provided with a throat, a frog, said stock portion being provided with an upper and a lower bearing for said frog, a rib connecting said two bearings, said frog being correspondingly grooved.

7. A plane having a stock portion provided with a throat, a frog, said stock portion being provided with an upper and a lower bearing for said frog, a screw having a seat between said bearings for securing said frog to said stock, a rib connecting said two bearings, said frog being correspondingly grooved.

To all whom it may concern:

Be it known that we, ALIX NV. STANLEY and HENRY S.WALTER, 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 improvements in the construction of planes.

The object of our invention is to provide a simple, inexpensive, and effective means for securing in place the means whereby the position of the cap of the plane is determined, as will he understood from the following description, taken in connection with the accompanying drawing.

In the illustration we have shown a side elevation of a plane fitted with an embodiment of our improved construction, parts of the plane being seen in section.

The plane which we have chosen to here describe is an iron plane, in which A is the bottom.

B is what is commonly termed the “frog” of the plane. This frog B is secured to the base and presents an inclined upper surface leading down to the slot in the base A, through which the plane-iron C projects. In this type C’ is a plane-iron cap, the two parts thus forming a double plane-iron. The iron C furnishes the cutting edge.

D is what is termed the “cap.” In the particular construction shown this cap is provided with a cam D’.

E is what is termed the “cap-screw” or “holder.” This part E is ordinarily in the form of a headed screw, which takes into a tapped hole in the frog B. This holder E is seldom if ever adjusted after it has been secured in its proper position, and it is desirable to have it snugly retained in that position, so that it will not work loose and disturb the adjustment or allow chattering of the parts when in use. At the same time it is desirable not to have a permanent connection in order that in the event of an emergency a new holder can be inserted. In case the cap should become broken or lost a new cap must be inserted, and if it should vary slightly in dimensions from the original cap the holder must be adjusted. It will therefore be seen that an adjustable cap-screw that will not become loose or accidentally disturbed from its proper position is the end which we seek to attain.

F is a lever or Y adjustment pivoted to the frog B, one end of which is adapted to engage with the plane-iron C, the other end being engaged by an adjusting-nut G. This nut or thumb-nut G is movable on a screw or post H, also carried by the frog B. The plane-iron may be advanced or retracted relatively to the bottom of the plane by means of the adjusting-nut G, which operates the lever F, engaging with the plane-iron, regulating the depth of the cutting edge in the usual manner.

Our invention will be found to consist in so arranging the screw-threaded or tapped passages in the frog B for the cap-screw E and the post H that the said passages intersect for the purpose of permitting the post H to be set up against the holder or cap-screw E when the latter is in its proper position.

We thus securely lock the parts in place to prevent their becoming accidentally displaced or loosened. The screw or post H therefore performs a double function. Not only is it a means for supporting the thumb-nut G for the adjustment of the plane-iron, but it also forms the locking means for the cap-screw or holder. In our preferred construction the thread of the screw E, adjacent the point where the end of the screw H is to engage and lock the same, is turned down, so as to remove the screw-threads. Consequently the end of the screw H will not batter the screw E and render it difficult or impossible to operate it when desired. Furthermore, by so doing a better bearing-face is afforded for the end of the locking screw or post H. Heretofore the frictional engagement of the screw-threads of the cap-screw E has been solely relied upon as the means for holding the screw in position.

By our improvement a simple, inexpensive, and effective means is provided whereby if the frictional engagement of the screw-threads is insufficient the movement of the cap~screw is nevertheless prevented.

The assembling of the plane is accomplished in the well-known manner, there being nothing to require special instructions in regard thereto. The plane-iron is inserted in the usual way, and the cap D is placed thereon, a keyhole-opening D2 in the cap allowing the cap to be slipped on over the holder E. It is then slid down into place, so that the head of the screw or holder E will stand over and engage the cap D. The cam D’ is then swung down into the position shown, and thus securely clamps the parts together. Should the cap-screw E become loose, the plane-iron or parts associated therewith will be likely to chatter, producing unevenness and other undesirable results in the work performed. This is entirely avoided by the employment of our invention.

It should be obvious that the improvements in the construction herein set forth are applicable to many different styles of planes, wood as well as iron, and that the bearing for the plane-iron instead of being a separate frog might be made an integral part of the plane itself, also that the particular form and arrangement are not material so long as the combination of cap-screw and post H is such that the latter element performs the double function of supporting the thumb-nut G and securing the cap-screw effectively in place.

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

1. In a plane, a plane-iron, a bearing therefor, a cap-screw for holding said plane-iron in engagement with said bearing, an adjusting-screw for regulating the position of said plane-iron, said adjusting-screw also engaging said cap-screw to lock it, substantially as described.

2. In a plane, a plane-iron, a cap-screw for holding said plane-iron in position, an adjusting-nut, a screw therefor, said screw engaging said cap-screw, substantially as described.

3. In a plane, a plane-iron, a cap-screw for holding said plane-iron in position, a portion of the thread on said cap-screw being turned down, a separate screw engaging the turned-down portion of said cap-screw, and an adjusting-nut mounted upon said separate screw, and means coacting with said adjusting-nut for shifting the position of the plane-iron without disturbing the adjustment of the cap-screw.

4. In a plane, a holding-screw E set into the frog B, an adjusting-nut working on a screw H, said screw engaging said holder to lock it in position, substantially as described.
