To all whom it may concern:

Be it known that I, JOHN JETT, a citizen of the United States, and a resident of San Francisco, in the county of San Francisco and State of California, have invented certain new and useful Improvements in Carpenters’ Planes, of which the following is a specification.

The objects I have in view are, first, to produce an adjustable plane in which the bit or plane-iron is held more firmly and is more easy to adjust than heretofore; second, to produce an adjustable plane in which the different parts are less liable to become disarranged than heretofore; and to this end the main feature of my invention consists in providing a roller which extends across the plane in front of the bit and about midway between the top and bottom of the plane-stock and having an improved gearing between the roller and bit by which the bit is given a slow and positive movement and by which the bit is held in any position without the use of any locking device.

Another feature is to have the roller connected to a lever on the outside of the stock and have a lug to hold the lever in place and prevent end movement of the roller.

Another feature is to provide a hood above the roller to protect, strengthen, and afford a continuous bearing for the same.

Another feature is to hold the bit and cap-plate more firmly together so they will not become disarranged when the bit is carried under the roller.

Another feature is to have the gearing adjustably attached to the cap-plate, so that the lever will occupy a convenient position when the bit is clamped to the stock.

These features are more fully described in the following specification, reference being had to the accompanying drawings, which form a part thereof.

Figure 1 is a side view of my improved plane ready for use. Fig. 9. is a longitudinal sectional view of the central part of the plane, showing the mechanism by which the bit is adjusted. Fig. 3 is an enlarged cross-section of the plane on the line 1 1 of Fig. 1, showing a sectional view near the left-hand side of the plane looking forward, the bit cap-plate and gear-plate not being shown. Fig. A is a top view of the gear-plate, cap-plate, and bit in their proper position, the roller being shown crosswise at the bottom. Fig. 5 is a cross-section on the line 2 2. of Fig. 4. Fig. 6 is a cross-section on the line 3 3 of Fig. 4. Fig. 7 is a top view of the lever for adjusting the bit sidewise. Fig. 8 is a longitudinal sectional view of the adjusting mechanism as applied to metal plane-stocks.

Similar letters refer to similar parts throughout the several views.

In the drawings, the letter S represents the plane-stock, which is cutout at the middle to receive the bit, the same as in the old-style wooden-wedge plane-stock. The stock is then cut to receive the bushing x, of which there is one on each side of the stock, and is held thereto by the screws x’, which enter the solid part of the stock, as shown in Fig. 2. The bushing serves as a bearing to receive the roller R, which extends through the stock about midway between the top and bottom in front of the bit. The roller is actuated by the lever L, which is rigidly attached thereto and is usually placed on the left-hand side of the plane, as shown in Fig. 1. These parts are held in place by the lug r on the bushing, a part of this lug being cut away to receive the beveled part l on the lever, and this beveled part is cutaway, as at l’, so as to pass the lug, and thus allow the roller to be removed and replaced at will.

The roller is provided with a double spiral groove G, Fig. 4, adapted to receive the V-shaped rib g on the gear»plate g’ I prefer to have this rib with a wider angle than the groove in the roller. Then the rib and groove will not be in exact alinement, and the groove itself is cut wider to receive the rib. This will cause the gear-plate to have a slower movement when compared with the roller and will give a finer adjustment of the bit.

The gear-plate is pivoted to the dovetail sliding member e bythe rivet e’. This member slides in the dovetail slot i, Fig. 6, in the cap-plate C and is made adjustable thereto by the bolt c and the nut c’. The cap-plate has a small section C’ cut out near its upper end, and this section is made adjustable to the bit B by the cap-bolt D and the nut d, which moves up and down in the dovetail slot i’ in the bit, and when the bolt is tightened the nut will be wedged into the slot, and thus held more firmly than where it is seated on a flat surface, and when it is desired to sharpen the bit the cap-plate is lifted off the adjustable section without loosening the screw. By this arrangement I dispense with the large hole which is usually placed at one end of the slot in the bit. I therefore make the slot of uniform width, which requires less work and less material.

Above the roller is the hood lt, which serves to protect the gearing and strengthen the roller and gives it a bearing the entire distance between the bushings. It extends from side to side on the inside of the plane, and its cross-section, as shown in Fig. 2, is uniform from side to side. It extends under the abutment a at each side of the plane, as shown in Fig. 3, and I prefer to have the semisleeve a’ on the bushing extend out flush with the abutment, as shown in Figs. 2 and 3, as this connects the hood firmly to the bushings; but this can be dispensed with, if desired. The abutment serves to hold the upper part of the hood firmly down on the roller and the lower part firmly down on the cap-plate, and when the roller is removed the hood is easily taken out.

I prefer to have the bed, or “that part just behind the bit,” cut away, as at f, Fig. 2, so as to allow the bit to spring when it is carried under the roller; but this can be avoided by having the bit curved upward in the middle when out of the plane. Then when it is carried under the roller it will spring almost straight.

The bit can be adjusted sidewise by a pivoted lever, the lower end of which enters the slot in the bit near the cap-screw similar to the ones now in general use; but this requires a long slot, and consequently a long bit, which is undesirable, and to avoid this I provide a lever N, which is pivoted to the brace b by the rivet b’. The lower end of this brace is attached to the stock and the upper end is attached to the handle H. It serves as a brace for the handle and also a support for the lever. The lower end of this lever is pressed or bent upward, as at n, and this part is provided with a slot n’, adapted to receive the lug d’ at the lower end of the cap-bolt. This lug can be attached to the nut d, as shown in Fig. 8, if desired. In either case it is attached firmly to the bit. It will be seen that the raised part n, extends up on each side of the rivet and serves to guide the lug into the slot when the bit is being placed in the stock.

It will also be seen that the old style wooden-wedge plane can be converted to use the mechanism here described and can then be used with the new or the old system, as desired. My improvement is also well adapted for metal plane-stocks, in which no bushing is required. The abutment a, Fig. 8, is cast or riveted on each side above the hood and serves the same purpose as described in the wooden stock. The brace b, instead of being a narrow strip as in the wooden plane, has its lower end widened, so as to extend the entire width of the stock, and is bent into the form of an angle. The vertical part t passes through a slot in the upper edge of the stock and is riveted on the outside. The horizontal part t’ rests on the upper edge of the stock. These two parts serve to hold the brace firmly to the stock and also serve to support the bit, which presses strongly thereon; otherwise the brace serves the same purpose as in the wooden stock. Another feature in this plane is the wooden fender w, attached to the bottom on the inside behind the bit. It may be an extension of the handle or may be a separate piece. It serves to prevent the edge of the bit from being dulled when it is being placed in the stock. Another feature is to pivot the gear-plate direct to the cap-plate and dispense with the dovetail sliding member previously described. This works well where the bottom of the plane is not subject to much wear and where the cap-plate is not shifted through a wide range.

When it is desired to remove the bit, the lever L is moved over to the front end of the stock, causing the gear to release the bit, which can then be taken out and replaced at will.

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

1. A plane having a plane-iron and a gearing adjustably attached thereto, the gearing consisting of a gear-plate with a V-shaped rib thereon, and having a roller passing through the stock in front of the plane-iron and having a lever attached to the roller on the outside of the stock, and having the roller provided with a double spiral groove adapted to engage the rib on the gear-plate and carry it forward under the roller and thus bind it firmly to the stock.

2. A plane having a plane-iron and a gearing adjustably attached thereto the gearing consisting of a gear-plate with a V-shaped rib thereon and having a roller passing through the stock in front of the plane-iron the roller provided with a double spiral groove with a less angle than the rib on the gear-plate and adapted to engage the rib and carry it forward under the roller and thus bind it firmly to the stock.

3. A plane having a plane-iron and a gearing adjustably attached thereto and having a roller passing through the stock in front of the plane-iron, and having a lever attached to the roller on the outside of the stock and having a lug adapted to hold the lever in place and prevent end movement of the roller and having the roller provided with gearing adapted to engage the gearing on the plane-iron and carry it forward under the roller and thus bind it firmly to the stock.

4. A plane having a plane-iron and a cap-plate and a gearing adjustably attached thereto and having a roller passing through the stock in front of the cap-plate the roller provided with gearing adapted to engage the gearing on the cap-plate and carry it forward under the roller and thus bind it firmly to the stock.

5. A plane having a plane-iron and a cap-plate with a small section cut out near its upper end and having the section adjustably attached to the plane-iron by a bolt and nut the nut being adapted to wedge into the slot of the plane-iron and having a gearing adjustably attached to the cap-plate and having a roller passing through the stock in front of the cap-plate the roller provided with gearing adapted to engage the gearing on the cap-plate and carry it forward under the roller and thus bind it firmly to the stock.

6. A plane having a plane-iron and a gearing adjustably attached thereto and having a roller passing through the stock in front of the plane-iron and having a hood above the roller on the inside of the stock adapted to strengthen the roller and afford a good bearing for the same, the roller provided with a gearing adapted to engage the gearing on the plane-iron and carry it forward under the roller and thus bind it firmly to the stock.

To all whom it may concern:

Be it known that I, GUSTAV DECHANT, a subject of the German Emperor, and a resident of Gerhardtstrasse 5, Kiel, Germany, have invented certain new and useful Improvements in Planes, of which the following is a specification.

My invention relates to improvements in planes holding several adjustable blades or bits; and its object is to provide a plane which may be used successively for different kinds of work, such as chipping, planing, finishing, rabbeting, &c., thus uniting several tools in one.

I attain my object by the construction illustrated herewith on the accompanying drawings, in which —

Figure 1 is a section on the line A B of Fig. 2; Fig. 2, a plan view of the same; Fig. 3, a front view of the casing for the blades hereinafter referred to; and Fig. 4, a section on the line C D of the said casing.

To the stock a of the plane there is secured in an oblique cylindrical aperture b a casing c, holding several blades or bits as they are used for several kinds of work, as above mentioned. The casing is adjustable in longitudinal direction by means of a set-screw d, pressing against the beveled surfaces e, and so adjustable that the said casing may be made sliding up or down. A leaf or small metal plate f is provided for securing the said casing in its position and preventing its disarrangement or untimely sliding upward, a small screw g pressing the said leaf against the casing. The blades or bits h, for the several kinds of work are provided within the said casing, which contains also a square tube k, against the surfaces of which the said blades are pressed and held fast by the small screws i.

In putting the plane to use I first give it the ordinary position which is for the coarsest work — the chipping. In order to use the tool for fmer or rabbeting work, I loosen the set-screw and turn the casing far enough to put the next blade or bit in position, and again the third and fourth. Marks l are provided to show how far the casing is to be turned each time to give it the position in which the several plates can be put to work. By turning on the screw each blade is kept fast, as aforesaid.

The above-mentioned square tube k may be substituted by any other suitable form, the number of blades depending on the number of surfaces of the said tube, so that each blade may be supported by a surface.

What I claim as my invention, and desire to protect by Letters Patent, is —

1. In a plane, the combination of the stock provided with an inclined cylindrical opening, a cylindrical casing having a beveled portion surrounding it, a plurality of tools carried by said casing, and a screw acting on the beveled portion of the cylindrical casing.

2. In a plane, the combination of a stock provided with a cylindrical oblique aperture, a casing with beveled surfaces, a square or other angular tube inserted in the said casing, several blades or bits contained in the said casing, each of the said blades or bits resting on a surface of the said angular tube, and screws for adjusting and holding fast the said casing and blades substantially as described.

In testimony whereof I have hereunto signed my name in the presence of two witnesses.

To all whom it may concern:

Be it known that I, ARTHUR J. REYNOLDS, 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 improvements in planes, and particularly to an adjusting-lever for the plane-iron.

The object of my invention is to simplify the construction of the same, lessen the cost of manufacture, and increase the general efficiency and ease of operation.

Figure 1 is a side elevation of a plane embodying the improvements of my invention. Fig. 2 is a side view, on an enlarged scale, of what may be termed the “adjusting-lever.” Fig. 3 is a top view of the same. Fig. 4 is a plan of a blank of sheet of wrought metal from which the adjusting-lever is formed.

1 indicates the body of the plane of suitable construction. The form herein is shown with a rear handle 2 and a front handle 3.

4 is a frog secured to the body portion by any suitable means.

5 is a cutting-iron of usual construction.

6 is a plate which may be used to reinforce the plane-iron and also afford a convenient means for cooperating with the adjusting mechanism.

7 is a cap-screw secured to the frog.

8 is a cap and 9 a clamping member.

All of the parts thus far described may be of any suitable construction.

The form of my invention which I have illustrated employs what is known as the “Y adjusting-lever” for varying the cutting depth of the plane-iron. This member is pivoted on pin 10, ordinarily carried by the frog 4. The adjusting-lever is formed of wrought or sheet metal blanked out in the form shown in Fig. 4 and afterward shaped up into the form shown in Figs. 1, 2, and 3. 11 indicates one of the ends of the duplex nose, which fits into a suitable recess in the plate 6, as is common. 12 indicates one end or arm of the adjusting-lever. 13 is the connecting portion in the form of a U bend between the two side arms and the duplex nose. This construction affords a broad bearing upon the pin 10 with the use of a small amount of metal, which is consequently economical and light in weight. The distance between the ends of the duplex nose affords a broad bearing for engagement with the plane-iron or plate.

14 is a post carried by the frog 4, and 15 is a sleeve which operates on the post 14 for cooperating with the arms 12 12 of the adjusting-lever. By means of this sleeve 15 the position of said lever may be varied to vary the depth of the cutting-iron as desired.

The forming of the adjusting-lever as shown affords great strength, since the U bend increases the strength at this point materially. The fiber of the metal is also so disposed at the point of contact with the plane-iron as to give a minimum amount of friction. The advantages of such a construction will be apparent to those skilled in the art.

What I claim is —

A plane-iron adjusting lever shaped to form arms at the respective ends for engaging the adjusting and the adjusted parts and an enlarged intermediate fulcrum portion comprising two side members united by a bend.

To all whom it may concern:

Be it known that I, OTTO BJORDAL, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Plane, of which the following is a specification.

My invention relates to improvements in planes which are provided with an adjustable blade and a handle to manipulate the same; and the objects of my improvement are, first, to provide a cam under the lower end of the blade to adjust the same; second, to provide a set-screw to assist in adjusting the blade; third, to afford facilities for shifting the upper end of the blade to either side; fourth, to provide a cheap and simple construction of the cap cam-lever; fifth, to provide means whereby the plane-handle can be filted into any desired position, and other objects which will become apparent from the description to follow. I attain these objects by the construction shown in the accompanying drawing.

Heretofore planes of this class were provided with means for adjusting the blade which required the blade to slide longitudinally while being tightly clamped in position. This construction often made it impossible to make a fine adjustment. With my construction the adjustment of the blade is accomplished by slightly bending or springing the blade and without moving the blade longitudinally in its bearing. This is made possible by placing a cam-shaft under the lower end of the blade, which has a lever connected to one end, and by moving the said lever forward and back the cam-shaft is rocked in its bearing so as to lower and raise the cutting edge of the blade. To securely hold the blade against any longitudinal movement, I provide a set-screw in the bed or frame of the plane, which is brought to bear against the head of the screw, which locks the blade and fore guide together. This construction enables the user to adjust the cutting edge of the blade to a thousandth part of an inch, or even finer, if found necessary, without the slightest danger of the blade being forced out of the adjustment while the plane is in use, as often occurs with the present construction of planes.

When the cutting edge of the blade is not ground exactly or straight across, it requires that the upper end of the blade be shifted from side to side. I accomplish this side movement by providing a rotatable disk in the blade, the upper exposed side of the disk being provided with a lever or thumb-piece and the lower side of the disk being provided with an eccentric-pin which engages a slot in the bed or frame of the plane.

The cap cam-lever of my device is pivoted in the end of the cap by having two oppositely-extending lugs resting in sockets provided in the cap, and no rivet or pin is used, as is the casein the present construction of planes.

It is often desirable for convenience while working to have the inclination of the handle of the plane changed, depending on the height of the mechanic using the plane and the height of the work from the floor. I make provision for such adjustment by having a curved slotted plate on the body of the plane and a headed bolt on the handle to move in said slot and a means for clamping the bolt securely in any position in the slot.

Referring to the drawing, similar reference characters refer to similar parts.

The body of the plane 10 is provided with the ordinary well or socket 11 for the reception of the blade 12 and its cooperating parts. While I have shown and will describe my invention in connection with a wooden plane it will be understood that the same can be applied to a metal plane.

The blade 12 is clamped tightly to the fore guide 18 in the ordinary manner by the screw 14. A bed-plate or frame 15 is rigidly secured to the oblique bottom of the well 11, and the blade 12 and fore guide 13 are tightly clamped to the same in the ordinary manner by the cap 16 and the cap-screw 17. The cap-lever 18 is pivotally attached to the cap by having its integral lugs 19 set into the sockets 20, provided in the cap 16, the cap 16 being slotted between the sockets 20 to permit the free passage of the lever 18. I provide a leaf-spring 21, riveted to the lower side of the cap, whose free end rests against the under side of the lever 18 and retains the lugs 19 in their cooperating sockets. The leaf-spring 21 also serves as a bearing-surface when the lever is operated. A depression or socket 22 is provided in the upper surface of the bed-plate 15 for the reception of the head of the screw 14, the depression 22 being somewhat larger than the head of the screw 14. A set-screw 23 is secured in the bed-plate 15, so arranged that it can be screwed against the head of the screw 14, and thus force the blade 12 down to any desired adjustment and also serves to prevent the blade from shifting upward when the plane is being used.

The blade 12 is intended to be set by the set-screw 23 so that it will make the very thickest cut desired, and to change the position of the blade to make a finer cut an elliptical or oval-shaped shaft 24 is mounted in a suitable groove in the bed-plate 15 under the lower end of the blade 12, which when rotated in one direction will lift the lower end of the blade 12, reducing the opening between the cutting edge and the body of the plane and when rotated in the reverse direction will allow the lower end of the blade 12 to return to its normal position. In certain constructions it may be desirable to place a plate between the shaft 24 and the lower end of the blade 12. To provide a convenient means for partly rotating the shaft 24, a flat lever 26 is rigidly secured to one end of the shaft 24 and extends upward beside the blade 12 to within easy reach of the operator.

I prefer to have the relative arrangement of the parts so that when the lever 26 is in its forward position to allow the blade 12 to assume its normal and lowermost position. To retain the lever 26 in any position, I provide a sheet-metal plate 27 between the lever 26 and the edge of the blade 12, securing it in place by a screw 28, which is screwed into the bed-plate 15, and to assist in holding said plate 27 firmly the shaft 24 passes through a hole in said plate. The upper edge of the plate 27 is bent out toward the lever 26 and is provided with ratchet-teeth 29, and that portion of the lever 26 contacting with the teeth 29 is provided with an extending edge or lip to cooperate with said teeth. The lever 26 is attached to the shaft 24 in such a manner that it will normally be held against the teeth 29, and when it is desired to move the lever forward it is first sprung out away from the teeth 29. To relieve this side strain on the lever from coming on the connection between the lever 26 and the shaft 24 and also to assist in holding the lever 26 against the teeth 29, a portion of the lower edge of the plate 27 is folded back against the lever 26, as at 30.

When the cutting edge of the blade 12 is not parallel with the base of the plane, it becomes necessary to move the upper end of the blade 12 to one side or the other, as the case may require, and to accomplish this side movement relative to the bed-plate 15 I provide a hole 31 in the blade 12, in which a disk 32 is mounted to rotate in the plane of the l blade. The under side of the disk 32 is provided with the eccentric-pin 33, which extends into the groove 34, provided in the bed-plate 15. A lever or thumb-piece 35 is provided on the upper side of the disk 32 to conveniently rotate the same. The disk 32 may be rotatably secured in the hole 31 in any desired manner; but I have found that a simple and cheap mode of effecting this is to have the under side of the hole beveled, as seen in Fig. 2, and have the edge of the disk swaged out at two points, as seen in Fig. 4, to rest against the beveled portion of the hole 31 and prevent the disk from being removed from said hole. The hole 31 may be provided with two notches which will register with the two swaged-out points on the disk when the disk is turned to a certain position, and thus permit the removal of the disk from the hole.

The blade 12 from constant use and regrinding is reduced in length, and to provide for the side adjustment of the blade at different lengths a plurality of holes 31 may be provided in the blade.

The handle 36 of the plane is made adjustable by securing a slotted plate 37 to the top of the body of the plane 10. A groove 33, larger than the slot 39, is made in the plate below the slot, and a bolt 40, secured in the handle, passes through the slot 39 and has its head resting in the groove 38. To secure the bolt 40 in the handle 36 and at the same time clamp the same to the plate 37, I provide an elongated nut 42 to be screwed on the end of the bolt 40 and rest against a shoulder 43, provided in the handle 36. The nut 42 has its end exposed and arranged to he turned by a wrench or screw-driver. The plate 37 and therefore the groove 38 and slot 39 are made to coincide with the arc of a circle, and to change the inclination of the handle 36 with relation to the plane 10 the nut 42 is loosened, the handle is moved along on the plate 37 to the desired position, and then the nut 42 is again tightened.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is —

1. In a plane, means for adjusting the cutting edge of the blade comprising a cam-shaft extending parallel with said cutting edge so arranged that the cutting edge of the blade will be raised and lowered by rotating said shaft.

2. In a plane, a blade clamped against the body, a groove in the body under the lower edge of the blade a cam-shaft resting in said groove, and a hand-lever rigidly secured to said cam-shaft, said parts being so connected and arranged that the cutting edge of the blade will be sprung by moving said hand-lever.

3. In a plane, a blade clamped against the body, a set-screw secured to the blade, a set-screw adjustably secured in the body contacting with the former set-screw to limit the longitudinal movement of the blade, a groove in the body under the lower edge of the blade, a cam-shaft resting in said groove, a friction-plate between the cam-shaft and the blade, a hand-lever rigidly secured to one end of said cam-shaft, and a rack secured to the body with which said hand-lever contacts to be retained in position, said parts being so arranged that the movement of the lever in one direction will spring the blade to raise the cutting edge, and a movement of said lever in the opposite direction will lower said cutting edge.

In testimony whereof l have signed my name to this specification, in the presence of two sub scribing witnesses, this 28th day of March 5 1904, at Chicago, Illinois.

To all whom it may concern:

Be it known that I, JOHN MUEHL, a citizen of the United States of America, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Planes; and I hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.

This invention relates to a new and useful improvement in bench-planes.

The object of this invention is to provide a device of this character which can be used on any kind of wood and will not clog or tear the wood.

A further object of my invention is to reduce the cost of manufacture and simplify the construction of bench-planes by providing a simple arrangement of bit-adjusting mechanism by means of which the bit can be easily and accurately adjusted longitudinally to regulate the depth of the cut and laterally to line up the edge of the bit with the sole or face of the plane.

My invention therefore consists in providing a plane having a plate secured in the stock thereof which serves both as a cap and as a clamping-plate and which also forms the sole support for all the adjusting mechanism.

My invention further consists in providing an arrangement of bit-adjusting mechanism by means of which the bit can be set by operating a single lever, by the rotation of which the longitudinal adjustment of the bit can be secured, and by the oscillatory movement of which the edge of the bit can be alined with the sole or face of the plane.

My invention further consists in the features of construction and combination of parts hereinafter described in the specification, pointed out in the claims, and illustrated in the drawings.

In the accompanying drawings, Figure 1 is a side elevation, partly in section, of my improved plane. Fig. 2 is a top plan. Fig. 3 is a section on line 3 3, Fig. 1. Fig. at is a section on line 4 4, Fig. 1.

Again referring to the drawings, 1 represents the stock of the plane, which is provided with the bit-opening or throat 2. A combined cap or clamping plate 3 is secured in the cheek-plates of the stock by means of pins 4 and 5. The lower edge of the plate 3 is provided with a knife-edge which is arranged flush with the sole or face of the plane.

Near the top of the plate 3 is formed a boss 6, in which is formed a screw-threaded opening 7. In the side of the boss and communicating with the opening 7 is formed a slot 20, and the opposite side of the boss is cut away, as at 21. In the screw-threaded opening 7 is arranged a screw-threaded plug 8, in which is formed an opening 9, the axis of which is at a right angle to the axis of the opening 7, and said opening is screw-threaded the greater part of its length. An adjusting-arm 10 is screw-threaded at one end and is arranged to screw into the screw-threaded opening 9 in the plug 8. The plug 8 therefore forms the fulcrum for the single adjusting-arm 10. In the end of the arm 10 is formed a screw-threaded bore 11. A small block 12 is provided with a screw-threaded stem 13, arranged to screw into the bore 11 in the end of the adjusting-arm 10. The exterior screw-thread on the lever 10 and the screw-thread in the plug 8 are preferably right-hand screw-threads, and the internal screw-threads in the end of the lever 10 and the screw-thread on the stem 13 are preferably left-hand screw-threads. In the block 12 is mounted a set-screw 14, which is provided with a reduced end portion 15. The arm 10 is preferably provided with a knob 16. A support 17 is rigidly secured between the cheek-plates of the stock, and between this support 17 and the plate 3 is arranged a bit 18. In this bit are formed a series of holes 19, arranged to receive the end of the set-screw 14, so as to secure the bit to the plate 3 and clamp it against the support 17.

The construction and operation of my plane is so simple that it can be readily understood.

When the knob of the arm is turned to the right, the end of the arm will be screwed down into the plug, thereby advancing the block and causing the bit which is secured thereto to project through the throat of the plane. By turning the knob of the arm to the left the arm will be screwed out of the plug, drawing the block into the plug and retracting the bit in the throat of the plane. Again, by swinging the arm to the left or to the right on the plug as a fulcrurn the opposite edges of the bit can be caused to project through or be retracted in the throat of the plane, thereby securing perfect alinement of the edge of the bit with the sole or face of the plane.

I have described and illustrated my preferred construction; but it will be readily seen that the same can be changed without departing from the spirit of my invention. For instance, most of the screw-threads are provided only for the purpose of allowing the members to rotate in their respective mountings, and any method of mounting which will permit a rotary movement of the members can be substituted and all screw-threads omitted except one on the arm 10 and a corresponding screw-thread either in the plug 8 or on the block 12 and any other means substituted which will allow a free rotary movement and supply a connecting or binding means at the same time.

What I claim is —

1. A plane comprising a stock, a stationary plate, an arm fulcrumed on said plate, and arranged to have both an oscillatory and a rotary movment, a bit, means for causing the arm to travel longitudinally when rotated, and means forming an operative connection between said arm and said bit so that the rotary movement of said arm will cause a longitudinal movement of said bit and the oscillatory movement of said arm will cause a lateral shifting of said bit so as to aline the cutting edge of said bit with the face of the plane.

To all whom it may concern:

Be it known that I, EDMUND A. SCHADE, a citizen of the United States, residing at New Britain. in the 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.

The object of my invention is to provide means for adjustment of the plane-iron and means for locking the same to prevent accidental movement.

The invention consists in improvements the principles of which are illustrated in the accompanying single sheet of drawings.

Figure 1 is a side elevation of a plane embodying the improvements of my invention. Fig. 2 is a detail fragmentary view showing the parts particularly necessary for comprehension out my improvement, a portion of the figure being shown in section.

1 indicates the body of a plane of any suitable construction. This in the form shown has handles 2 and 3. 4 is a frog of any suitable construction which provides a bearing for the plane-iron 5. 6 is a plate winch serves to reinforce the plane-iron and in this particular instance affords the means of connection for the adjusting mechanism. 7 is a cap-screw which takes into the frog in any well-known manner. 8 is a cap coacting therewith, and 9 is a clamp for holding the parts in their proper position. All of these parts thus far described may be of any suitable construction.

The cutting depth or position of the plane-iron may be varied by means of a lever, which is commonly termed a “Y adjustment.”

In the drawings, 10 indicates a pivot-pin carried by the frog and upon which the adjustment-lever is mounted.

11 is the nose of the lever, and 12 is one of the depending arms.

13 is a screw-post which is securely fastened to the frog 4.

14 is an operating-sleeve mounted to operate on the post 13 and having, preferably, a milled head 15.

16 is a shoulder or flange carried by the inner end and adapted to coact with the arm 12 of the adjusting-lever.

17 is a member which is carried by the sleeve 14. This aliords a bearing for one side of the arm 12 of the Y adjustment, so that when the sleeve 14 is moved longitudinally on the post 13 the arm 12 is rocked to and fro to move the cutting-iron.

The adjusting-sleeve 14; as commonly constructed is likely to accidentally turn and move on the post 13 as the plane is used. This results sometimes in derangement of the adjustment of the plane and at all times tends to wear the parts unduly. By my construction this is avoided. The member 17 is preferably milled on the edge and may be adjusted on the post 14 to securely engage the arm 12 and clamp the same in position against the flange 16. The friction of the parts against the arm 12 serves to prevent the adjusting-sleeve from rotating on the post 13. As a consequence the adjusting-lever cannot move and the sleeve has no free play to cause wear on the parts. The plane-iron may be adjusted by releasing the clamping mernber 17 and then operating the adjusting-sleeve. The advantages of this construction will be apparent to those skilled in this art.

What l claim is —

1. In a plane, the combination of a body portion, a frog, a plane-iron and adjusting member, a post, a sleeve adjustable on said post and coacting with said member and a clamping member mounted on said sleeve and also coacting with said member for the purpose specified.

2. In a plane, the combination of a body portion, a frog, a plane-iron, an adjusting member coasting therewith, a screw-threaded post, an adjusting-sleeve screw-threaded on said post, a clamping-sleeve screw-threaded on said adjusting-sleeve and rotatable therewith and also independently thereof said sleeve and clamping member coacting with said adjusting member for the purpose specified.

To all whom it may concern:

Be it known that I, ALBERT WILLIAM CAMPBELL, a citizen of Great Britain, residing at Glastonbury, in the county of Somerset, England. have invented certain new and useful Improvements in Planes, of which the following is a full, clear, and exact description.

My invention relates to improvenients in planes, and particularly to adjusting mechanism for double-ended planes.

The object of the invention is to provide a simple and inexpensive means for adjusting the plane-iron in a double-ended plane, which adjusting means shall be reversible to cooperate with the plane-iron in either its front or rear position, so as to vary the cutting depth when desired.

The invention consists in providing, first, a plane-body having two openings or throats in the sole portion and supports for the plane-iron for both of these throats; second, a plane-iron and a clamping member with means for holding them in place; third, adjustable and reversible means for projecting or retracting the plane- iron through either one of the throats, as desired.

The details of my invention will be more clearly seen on an inspection of the accompanying single sheet of drawings, in which —

Figure 1 is a side elevation of a plane embodying the improvements of my invention, the plane-iron being projected through the forward throat. Fig. 2 is a central longitudinal section of the plane with the iron projected through the rear throat. Fig. 3 is a plan view of the plane-body and the adjusting mechanism in the position of Fig. 2, the plane-iron and clamp being removed. Fig. 4 is a vertical cross-section taken on the plane of the line 4 4, Fig. 3.

1 indicates the sole portion of the plane. 2 and 3 are the side flanges which reinforce and strengthen the same 4: is the front throat or opening through which the cutting edge of the plane-iron may project.

5 is the rear throat.

6 is a handle which may be conveniently provided at the fore end of the plane.

7 is a plane-iron which at its cutting edge is supported by a portion of the sole.

8 and 9 are supports for the plane-iron 7 intermediate the throats 4; and 5.

10 is a cap member which bears against the plane-iron near the lower end.

11 is a clamping member carried by the cap which coacts with the plane-iron.

12 and 13 are cross-bars supported by the flanges 2 and 3 of the plane. The cap is inserted beneath one of these cross-bars, and the clamp 11 holds the parts in place.

14 is an adjusting-block having a projection 15 at the upper end for coacting with a recess or perforation in the plane.-iron.

16 is an adjusting-screw for coacting with the adjusting-block to move it back and forth, so as to vary the cutting depth of the plane-iron.

17 is a pivoted step for the adjusting-screw.

18 is a washer over which the lower end of the adjusting-screw is riveted to hold the same in place, so as to prevent the adjusting-screw from moving longitudinally with relation to the step 17.

19 and 20 are pivot-screws which extend through the side flanges 2 and 3 and also through the supports 8 and 9 and are screwed into the step 17. The lower end of the adjusting-block is guided between the inner faces of the supports 8 and 9, and thus prevented from rotation with respect to the adjusting-screw. The rotation of the adjusting-screw thus causes longitudinal movement of the plane-iron.

21 is a wheel or roller carried by the adjusting-screw 16, which rests upon the cross-bar 12 when the parts are in the position shown in Fig. 2. This supports the adjusting-screw toward the upper end. Of course when the plane-iron is reversed the cap 10 is inserted under the rod 12 and the wheel 21 rests on the rod 13, the adjusting and clamping means being reversible and interchangeable in this respect.

It will be obvious to one skilled in the art that many changes and alterations might be made in the construction shown in the drawings without departing from the spirit or scope of my invention.

What I claim is —

1. In a double-ended plane, a body portion having two throats, a plane-iron and reversible means for adjusting the cutting depth of the iron at either throat.

2. Adouble-ended plane comprising a body portion having two throats, a plane-iron and a pivoted reversible means for adjusting its cutting depth of said plane-iron through either of said throats.

3. A plane comprising the combination of a body portion with two throats, a step, pivots therefor, a screw coacting with said step and an adjusting-block operated by said screw.

4. In a plane, a body portion having side flanges and two throats in the sole, a plane-iron, clamping means therefor, two rods connecting said flanges, supports between said throats for said iron, a step, an adjusting-screw for said iron coacting with said step and adapted to coact with either one of said rods for support.

5. In a plane, a. body portion having two throats, supports between said throats, a plane-iron, a reversible adjusting-block therefor, a guide for said block to the rear of each throat to prevent its rotation and a screw coacting with said block for the purpose specified.

6. In a plane, a body having two throats, two supports therein, a plane-iron, a step pivotally mounted between said supports, an adjusting-block, and a screw coacting with said step and said block.

To all whom it may concern:

Be it known that we, JOHN W. CARLETON and GEORGE E. TRASK, citizens of the United States, residing at New Britain, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Plane-Iron-Adjusting Devices, of which the following is a specification.

Our invention relates to improvements in plane-iron-adjusting devices; and the object of our improvement is convenience and efficiency in use.

In the accompanying drawings, Figure 1 is a sectional side elevation of our plane-iron adjustment, together with so much of a plane as is deemed necessary to show its connection therewith. Fig. 2 is a plan view of the major part of the said adjusting devices and a portion of the plane-stock, the upper adjusting-nut and the plane-irons being removed. Fig. 3 is a plan view of the longer arm of the operating-lever in a modified form.

Our improvement relates to the longitudinal adjustment of the plane-iron or cutting-bit when frictionally held in place on its seat by a bit-clamp.

A designates the stock, which may be of any known or ordinary construction.

3 is the hub of the operating-lever, the said lever having a short arm or tooth 4 for engaging the cap-iron 5 and a longer operating-arm 6 by which to move the said lever. The cap-iron 5 is secured by a screw 7 to the plane-iron or cutting-bit 8 in the ordinary manner, so that when in use the said cap is rigid with the plane-iron, whereby moving the cap longitudinally also moves the plane-iron longitudinally. Any known connection of the short arm or tooth of the lever with the plane-iron may be substituted for the cap connection therewith which is herein shown. The plane-iron 8 is seated in the ordinary position on a fixed seat of the stock A, and underneath this plane-iron the operating-lever 3 4 6 is pivoted in any proper manner — as, for example, by the pin 9, which extends through the hub 3 of the said lever and uprights or supports 10 of the stock. The longer arm 6 of the operating-lever is provided with an opening for the admission of the screw-post 11 that is rigidly mounted on the stock and projects upwardly at substantially a right angle to the length of the said operating-arm when the said arm is in its central or intermediate position. This opening may be in the form of a slot 12 near the outer end of the said arm, as shown in Fig. 2, or a notch 13, that extends from the outer end of the said arm inwardly, as shown in Fig. 3. Two separate adjusting-nuts 14 are mounted on the screw-post 11, one of the said nuts being above the operating-arm and the other below it. The upper one of these nuts is removed in Fig. 2.

The operating-lever, substantially as herein shown and described, without the screw-post and nuts is older than the date of the invention upon which this application is based, and hence the said lever of itself is not claimed herein.

The outer end of the longer arm 6 of the operating-lever constitutes a handle by means of which the lever when free may be moved in either direction. The two separate adjusting-nuts 14 are each single-acting nuts for acting on one side only of the lever. The friction of the ordinary bit-clamp is depended upon to hold the cutting-bit and the operating-lever in their places when one or both of the nuts are out of contact with the said lever.

With our improvement when both nuts are turned so as to bear snugly against the opposite sides of the longer arm of the operating-lever the said lever is positively held against moving in either direction. If it is desired to raise the outer end of the operating-arm for adjusting the plane-iron downwardly and outwardly, the upper nut is loosened a little and the opposing or under nut tightened up, and vice versa. The operator can readily see which way to move the nuts to effect the desired adjustment. Some workmen never lay away the plane without first drawing the plane-iron inwardly so as to protect its cutting end. Then when they begin work again the plane-iron has to be readjusted. With our adjustment when it is desired to draw in the plane-iron to protect the cutting end it is only necessary to loosen the lower nut a little and then depress the outer end of the operating-arm by the application of one’s finger or thumb without moving the upper nut at all. Then when the plane is again wanted for use it. is only necessary to raise the operating-arm of the lever by means of the handle until it is stopped by the upper nut. Then bring the lower nut up into place to bind the said arm against the upper nut and the cutting-bit will be restored to the particular adjustment that it had when laid away. In this connection it may be noted that there is a complete and operative combination with the outer nut only, the upper nut as herein shown-that is to say, when the lower nut is run down so as to be out of action the lever may be brought up against the upper nut as a stop, and the cutting-bit will be thus adjusted to whatever position the said nut may be set and with substantially the same degree of fineness that can be had with the ordinary double-acting nut that always leaves the lever free in one direction to a limited extent. Thus when only the upper one of the nuts is employed and the desired adjustment has been made the operator may depress the lever to draw in the edge of the cutting-bit for laying the plane away and on resuming work may force the cutting edge out again by merely raising the handle until the lever strikes the said upper nut. The friction caused by the bit-clamp will hold the bit in its adjusted positien, and it will be adjusted with a fair degree of accuracy. By the use of the two single-acting nuts, when both are firmly seated in place, all the give or spring of the parts is taken up so as to make the adjustment positive. Now by first loosening one nut and then tightening up the other to move the lever either way from this positive or rigid adjustment we are enabled to adjust the cutting-bit with the iinest kind of action. At the same time the lower nut may be readily spun down out of the way for permitting the cutting-bit to be moved in and out by hand in the manner before described.

It is apparent that some changes from the specific construction herein disclosed may be made, and therefore we do not wish to be understood as limiting ourselves to the precise form of construction shown and described, but desire the liberty to make such changes in working our invention as may fairly come within the spirit and scope of the same.

We claim as our invention —

1. In a plane, the combination of a cutting-bit with a bit-clamp for frictionally holding the said bit in place on its seat, a lever for moving the said cutting-bit longitudinally on its seat under the said bit-clamp, the said lever having a short arm connecting it with the said cutting-bit, and a longer operating-arm having a handle, a fixed screw extending in the line of movement of the said operating-arm and a single-acting nut mounted on the said screw at the outer side of the said arm and acting on the said side only, leaving the lever free to be moved by the handle in the direction for withdrawing the edge of the cutting-bit substantially as described.

2. In a plane, the combination of a cutting-bit with a bit-clamp for frictionally holding the said bit in place on its seat, a lever for moving the said cutting-bit longitudinally on its seat under the said bit-clamp, the said lever having a short arm connecting it with the said cutting-bit and a longer operating-arm having a handle, a fixed screw extending in the line of the movement of the said operating-arm, a single-acting nut mounted on the said screw at one side of the said operating-arm for acting on that side only, and a second single-acting nut mounted on the said screw at the opposite side of the said operating-arm for acting on that side only, substantially as described.

Application filed June 11, 1903. Serial No. 161,054. (No model.)

_________________

To all whom it may concern:

Be it known that I, ERIC O. SJOLANDER, a citizen of the United States, residing at Deepwater, in the county of Harris and State of Texas, have invented a new and useful Bench-Plane, of which the following is a specification.

This invention relates generally to bench-planes, and more especially to means for adjusting the bit in the stock and means for securing the bit in adjusted position.

One object of the invention is to provide in a bench-plane an improved form of mechanism for adjusting the position of the bit in the stock, so that the depth of cut may be accurately adjusted and so that the edge of the bit may be brought into perfect parallelism with the face of the stock.

A further object of the invention is to provide in a bench-plane a bit bearing a scale and a bit-clamping plate bearing an indicator to cooperate with the scale on the bit to show when the bit and the clamping-plate have been brought into proper relation.

A further object of the invention is to provide in a bench-plane single means for adjusting the depth of the cut and for swinging the bit laterally on a suitable fulcrum to bring the cutting edge into parallelism with the stock.

In attaining the objects above stated and others which will hereinafter appear I make use of the construction and combination of parts of a bench-plane hereinafter described and claimed, and illustrated in the accompanying drawings, in which corresponding parts are designated by the same characters of reference throughout, it being understood that changes in the form, proportions, and exact mode of assemblage of the elements may be made without departing from the spirit of the invention.

In the drawings, Figure 1 is a view in vertical longitudinal section through the plane. Fig. 2 is a view of the plane-stock and bit-support. Fig. 3 is a view in perspective of the bit-clamping plate, showing the recessed back. Fig. 4 is a perspective view of the adjusting screw and block. Fig. 5 is a plan view of the bit and the bit-clamping plate, showing the clamping-plate adjusted in position by means of the scale on the bit.

Referring to the drawings in detail, 1 designates the plane-stock, which may be of wood or metal and of any of the ordinary forms. The stock is provided with the usual opening 2 for the passage of the bit, and on the upper surface of the stock, at the rear margin of the opening 2, is provided a supporting structure 3, the forward surface of which forms a continuation of the rear wall of the opening 2. The bit 4 consists, preferably, of a single plate of steel provided at its lower end with a cutting edge and having at 5 a slot with enlarged and rounded ends for the passage of the head of a screw 6, mounted in the lower end of the supporting structure. The width of the slot 5 between the rounded end portions is of such width as just to permit of the passage of the shank of the screw 6, which is designed to serve as a fulcrum, upon which the bit 4 may be swung laterally. The bit is provided near the butt with round openings 7, for purposes that will presently appear, and along one lateral margin of the bit is formed a scale 8, for use in connection with an indicator formed on the bit-clamping plate.

The supporting structure 3 is vertically slotted at 9 from the upper end almost to the base, and at the lower end of the slot 9, which tapers slightly toward the bottom, are provided a pair of oppositely-disposed ribs 10, which lie in a plane substantially at right angles with the front surface of the support. At either side of the slot 9 is an arm 11, on the forward surface of each of which is formed a shallow recess 12 to form a way for the movement laterally and transversely of the support of one of the wings 14 of a block: 13, which is carried on the screw 15, which is supported in the slot 9 in a manner presently to be explained.

The body portion of the block 13 is sufliciently narrow to be susceptible of considerable lateral movement in the slot 9, and the wings 14 are of such proportions that they will have a similar degree of lateral movement in the recesses 12. On the forward surface of the block 13, which lies substantially flush with the forward surface of the supporting structure 3, is provided a stud 16, which is adapted for engagement with either of the round openings 7 in the plane-bit. When the parts of the plane are assembled, the stud 16 will always be brought into engagement with one of the openings 7, and when the parts are so connected the movements of the block 13 will be communicated to the bit, and conseqently any shifting of the block 13 will change the position of the bit correspondingly.

The screw 15, upon which the block 13 is carried, is provided at its upper end with a head 17 of suitable form to facilitate the rotation of the screw, and at the lower end the screw has a reduced portion which is not threaded. At the extremity of the reduced portion a collar 18 is rigidly attached, and loose upon the reduced portion between the collar 18 and the threaded portion of the screw is a second collar 19. The opposite faces of both collars 18 and 19 are rounded, as best seen in Fig. 1, and when the collars are spread apart sufficient space is provided between them to permit the passage of the ribs 10, which are spaced apart sufficiently to allow the reduced portion of the screw to be introduced between them. The rounded faces of the collars 18 and 19 permit the screw 15 to be shifted laterally with the reduced portion between the ribs 10 as a pivotal point.

In order to clamp the bit 4 rigidly in proper relation to the stock 1, I provide a bit-clamping plate 20 of the form generally used, which is provided about midway of its length with a slot 21, having the lower end thereof enlarged and rounded to permit the passage of the head of the screw 6. At the upper end of the bit-clamping plate a cam-lever 22 is pivotally mounted in a slot 23 in the clamping-plate, and on the rear surface of the clamping-plate, which is preferably recessed, as shown in Fig. 3, there is provided near the upper end of the plate a tongue 24, of thin metal, which is rigidly attached at its lower end to the clamping-plate and has the upper end thereof, which is free, disposed under the cam on lever 22. The tongue 24 is provided to prevent the contact of the cam with the bit 4, as the contact of the cam with the bit would tend to throw the bit out of adjusted position.

On the side of the clamping-plate 20 which corresponds in position to the scale 8 on the bit there is formed a shoulder 26, which is adapted to serve as an indicator in connection with said scale and to show by the coincidence of the shoulder with one of the divisions of the scale when the clamping-plate has been brought into proper relation to the bit.

In assembling the parts of the plane for use the mode of procedure is as follows: The clamping-plate 20 and the bit 4 will first be brought into proper relation, as shown in Fig. 5, and the division of the scale with which the shoulder on the clamping-plate coincides will be noted. The bit will then be introduced into the opening in the stock, and the stud 16 on the block 13 will be brought into engagement with one of the openings 7 in the bit. If the bit is new and unworn, the lower opening will be employed, and if the bit is old and much worn the upper opening will be used. The bit having been operatively connected with the block 13, the screw 15 will be rotated by means of the head 17 on the end thereof until the edge of the plane-bit has been protruded beyond the face of the stock to the distance required for the proper depth of cut. Then the screw 15 will be swung laterally, if necessary, to bring the edge of the bit into perfect parallelism with the face of the stock. During the adjustment the operator will hold the plane in such position that the relation of the edge of the bit with the face of the stock may be accurately observed. When the bit has been properly adjusted, the clamping-plate 20 will be placed in position on the forward surface of the bit, with the screw 6 extending through the opening 21 in the plate. The clamping-plate will then be brought into exact position in relation to the bit by causing the shoulder 25 to coincide with the division of the scale 8, previously noted, and the cam-lever 22 will then be operated to secure the clamping-plate in adjusted position.

From the foregoing description of the construction and mode of adjustment of the plane it will be seen that the adjustment of the bit in relation to the plane-stock is effected independently of the adjustment of the clamping-plate and that the relative positions of the clamping-plate and bit to produce the desired result having been noted at the beginning of the operation of adjustment of parts of the plane the clamping-plate may be brought at once into proper relation to the bit and secured without deranging the adjustment of the bit in relation to the stock. It will also have been observed that by providing a scale on the bit and an indicator of a suitable form on the clamping-plate a degree of accuracy of adjustment of the clamping-plate and bit may be secured, which is impossible in planes not so constructed.

A special advantage inherent in the construction hereinbefore described is in the mode of supporting the screw 15 and the adjusting-block 13, by which it is made possible to effect the adjustment of the plane-bit as to depth of out and as to parallelism with the face of the stock by a single adjusting means.

Having thus described the construction and operation of my invention, what I claim as new, and desire to secure by Letters Patent, is —

1. In a bench-plane, the combination of a bit bearing a scale located above the mouth of the plane, and a bit-clamping member having an indicator adapted to cooperate with said scale.

2. In a bench-plane, the combination of a bit bearing a scale above the mouth of the plane, and a clamping member having a shoulder adapted to form an indicator for cooperation with said scale.

3. In a bench-plane, the combination of a bit having a scale located along one lateral margin thereof above the mouth of the plane, and a clamping member having an indicator adapted to cooperate with said scale.

4. In a bench-plane, the combination of a bit, a support for the bit having a slot within its supporting range, a block supported in said slot and susceptible of movement longitudinally and laterally therein, said block being adapted for positive connection with the bit, and a pivoted member mounted within said slot along which said block is longitudinally movable.

5. In a bench-plane, the combination of a bit, a block adapted for positive connection with said bit, and a screw upon which said block is supported, said screw being pivotally mounted to swing laterally.

6. In a bench-plane, the combination of a bit, a bit-support having a longitudinally-arranged slot, oppositely-disposed ribs provided at one end of the slot, a screw arranged in said slot having collars near one end for loose engagement with said ribs and a block mounted on said screw and adapted for lateral and longitudinal movement in said slot and also adapted for positive connection with said bit.

7. In a bench-plane, the combination of a bit, a bit-support having a longitudinaly-disposed slot, oppositely-disposed ribs, at the lower end of said slot, a screw arranged in said slot and having at the lower end collars spaced apart and having the opposite faces rounded for engagement with said ribs, and a block mounted on said screw and adapted for positive connection with said bit.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.

To all whom it may concern:

Be it known that we, JOHN W. CARLETON and GEORGE E. TRASK, citizens of the United States, residing at New Britain, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Planes, of which the following is a specification.

Our invention relates to improvements in planes; and the objects of our improvement are simplicity and economy in construction and convenience and efficiency in operation.

In the accompanying drawings, Figure 1 is side elevation of our plane. Fig. 2 is a central longitudinal section of the same, partly in elevation. Fig. 3 is a plan view of the same with the holding-cap, cap-iron, and cutting-bit removed. Fig. 4 is a side elevation of the middle portion of the iron frame of the stock. Fig. 5 is a side elevation of our plane when made with an iron stock without the wooden body. Fig. 6 is a sectional view of the same on the line x x of Fig. 5 when viewed in the direction of the dart in the said Fig. 5, the cutter being removed. Fig. 7 is a sectional side elevation of the middle portion of the stock and the adjusting-levers. Figs. 8 and 9 are plan and reverse plan views, respectively, of the cutting-bit with attached cap-iron and adjusting-nut, the same being adapted for use in both of the constructions herein shown. Fig. 10 is a plan view of the holding-cap and its screw.

A designates the wooden body, and B the iron frame, the said two parts together forming the stock of the plane. If desired, the wooden body A of the stock may be provided with a metal sole 5; but this is not essential. The frame B has an end plate 6 at its forward end provided with a hole for receiving the holding-screw 7 and also with a seat for the knob 8, the said seat being centrally perforated to receive the screw 9, that serves the double function of securing the said knob in place and of assisting to secure the said frame to the wooden body of the stock. At the rear end of the plate 6 there is a cross-rib 10, and extending rearwardly from the ends of the said cross-rib at opposite sides of the stock are the two side pieces 11 of the iron frame B, with the holding-lugs 12 on their confronting inner faces over the opening for the throat 13 of the stock. These side pieces 11 extend parallel to each other along the sides of the stock to a point in the rear of the middle of the length of the stock and then turn inwardly toward each other to the handle-seat 14 on the rear plate 15, near the end of which is the hole for the holding-screw 16. An ordinary handle 22 is secured to the handle-seat 14 by the rod 17, which is screw-threaded at its ends, one end being screwed into the threaded boss 18 on said handle-seat, while the other end is provided with the holding-nut 19.

The rear plate 15 extends forwardly to the side wings 20 of the frog, into which the said plate merges. An opening 21 is left in the rear plate between the said side wings 20 and rearwardly thereof. to near the handle 22. The side wings 20 of the frog are connected together near their upper ends by a bridge 23. The inclined front faces of the two side wings of the frog and the adjacent part of the rear plate form a seat for the cutting-bit in continuation of the inclined rear wall 24 of the throat of the stock. The side wings 20 of the frog are formed with a lug 25, Fig. 4, that extends below the base of the frame side pieces 11, and between these lugs we pivot a hub 26, having a short lever-arm 27 for engaging a slot in some device connected with the cutting-bit 28 or its cap-iron 29. The said hub is also provided with a longer lever-arm 33, that extends rearwardly from the hub for use as a handle in operating the said short lever-arm and cutting-bit for its endwise adjustment. Such levers of themselves, broadly speaking, are not of our invention. As shown, the short arm 27 of the lever engages a slot 36, Fig. 9, in the head of the screw 30, Fig. 2, which is held in the ordinary longitudinal slot of the cutting-bit 28 by means of the nut 31, the head of the said screw being shouldered by slabbing off on each side, as at 32, Fig. 2, so that the slabbed-off portion of the screw-head may enter the slot in the bit. On the upper face of the bridge 23 we pivot an ordinary laterally-adjusting lever 34. We secure the cutting-bit in place by means of a holding-cap C, the lower end of which is inserted under the confronting holding-lugs 12, after which the parts are tightened by turning in the holding-screw 35 at the upper end of the holding-cap C.

The stock Ba as shown in Figs. 5, 6, and 7, is wholly of iron and quite closely resembles the iron frame B, before described, only it is not adapted to have a wooden body secured thereto, and consequently its side pieces 11a are extended parallel to each other for nearly the whole length of the stock. These side pieces have on their inner faces the holding-lugs 12, before described. The side wings 20a of the frog are substantially the same as before described, only they are proportionally longer as the height of the inclined rear wall 24a of the throat 13 in the iron stock is less than in the wooden body of the stock first described. Like the side wings first described, a bridge 23 is provided to connect their upper ends. While there is an open space between the side wings 20a for pivoting the hub 26 of the lever 27 33, the pivot of the said lever comes higher up on the wings, and the lugs, which in the first-described construction project downwardly below the base of the wings, are omitted. The pivot-pin 37 for the hub 26 may for convenience of heading it pass through the side pieces 11a as well as the wings 20a The cutting-bit and connected parts and both of the adjusting-levers are the same as first described and have the same reference-numerals.

We claim as our invention —

1. In a plane, the frame of the stock having the side pieces 11, a frog between the said side pieces having the side wings with open space between, and the bridge 23 connecting the upper corners of the said side wings, which bridge forms a support for the laterally-adjusting lever.

2. In a plane, the stock having the side pieces, a frog between the said side pieces having the side wings with open space between, a bridge connecting the upper ends of the said side wings and forming a support for a laterally-adjusting lever, and an adjusting-lever consisting of a hub, short arm and longer operating-arm, the same being pivoted in the open space between the lower part of the said side wings and in front of the said bridge, with the body of said operating-arm working between the said wings while its handle end extends under the said bridge beyond the said wings at the rear thereof.

3. The herein-described plane, comprising the wooden body and iron frame of the stock, the said frame having the front and rear plates, connecting side pieces, and the frog between the said side pieces having the side wings with open space between and bridge at their upper corners forming a support for the laterally-adjusting lever.

4. The herein-described plane, comprising the wooden body and iron frame of the stock, the said frame having the front and rear plates with knob and handle seats, side pieces connecting the said plates and the frog between the said side pieces, the said frog having the side wings with open space between, the inclined front faces of the said side wings and the adjacent part of the said rear plate forming a direct seat for the cutting-bit, while the lower parts of the said side wings form a support for the longitudinaliy-adjusting lever.

5. The herein-described plane, comprising a wooden body and frame of the stock, the said frame having front and rear plates, connecting side pieces with the confronting holding-lugs on their inner faces, a frog between the said side pieces having the side wings with open space between, a bridge at the upper corners of the said wings forming a support for a laterally-adjusting lever, and lugs at the lower corners of the said wings for the longitudinally-adjusting lever.

6. In a plane, the stock having side pieces, a frog between the said side pieces composed mainly of a pair of inclined side wings with open space between, and aconnecting-bridge 23, at the upper ends of the said side wings that spans the said open space between them, the said side pieces forming a support for the longitudinally-adjusting lever and the said bridge forming a support for the laterally-adjusting lever, substantially as described.

7. In a plane, the stock having side pieces, a frog between the side pieces having the side wings with open space between, a longitudinally-adjusting lever with its long and short arms pivoted between the said side wings with the upper end of the said long arm projecting rearwardly from the space between the said side wings, a bridge connecting the upper ends of the said side wings, and a laterally-adjusting lever pivoted on the said bridge.

To all whom it may concern:

Be it known that I, LUCAS C. CLARK, a citizen of the United States, and a resident of Southington, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements Applicable to Planes, of which the following is a description, reference being had to the accompanying draivings, wherein —

Figure 1 is a side elevation of a plane embodying my invention. Fig. 2 is a side sectional view, on an enlarged scale, of part of the plane with my invention applied thereto. Fig. 3 is a detail view on the line x x of Fig. 2 looking in the direction of the arrows. Fig. 4 is a detail view on the line y y of Fig. 2 looking in the direction of the arrows. Fig. 5 is a view of the structure shown in Fig. 3 with the parts separated. Fig. 6 is a detail view of the block shown in Fig. 4. Fig. 7 is a view of a plane in side elevation with a modified form of my invention. Fig. 8 is a sectional elevation, on an enlarged scale, of a part of the plane embodied in my invention. Fig. 9 is a detail view of a member shown in Figs. 7 and 8.

The object of the improvement is the production of a device for adjusting the cutting-blade of the plane, which has features of novelty and advantage.

Referring to the drawings, 1 denotes the plane-body; 2, the handle. 3 is what is known as the “frog,” at the blade, 4a the cap-plate, and 5 the clamp, these parts being arranged substantially as they are in an ordinary plane. 6 is the lever for controlling the lateral adjustment of the blade. All of these parts are of the ordinary construction, and no novelty is claimed for them.

On the upper end of the frog 3 is cast the lug 7, slotted, as at 8, having a cap or filling piece 9, adapted to be held in place in the slot by the screw 10. When this cap or filing piece is in place, a hole is left through the lug 7. A screw 11, adapted to fit in the hole through the lug 7, has at one end a head 12, which bears on one side of the lug, and a collar 13, which bears on the opposite side of the lug, as clearly shown in Fig. 2. This screw is held in place in the lug by the cap or filling piece 9 and a screw 10. Beyond the collar is a screw- threaded portion which passes through the block 14, which is threaded to correspond with the threads on the screw. This block 14 has at its upper end a projecting lug 15, which is adapted to enter the aperture in the cap-plate 4a and is capable of movement lengthwise along the screw 11 in a slot 16 in the frog 3. The upper surface of the head of the screw is notched, as at 17, and a lever 18 has a lug 19, adapted to fit the notches in the head of the screw, and is mounted on the pin 20 and normally held against the head of the screw by a spring 21.

It is evident that any rotary movement of the lever 18 when intermeshed with the head of the screw will turn the screw 11, and so move the block 14 along the screw in either direction, depending upon the direction of movement of the lever. Because of this connection of this block with the blade such a movement of the block as above noted will carry the blade up or down. In the constructlon shown in the drawings the block moves the cutting-blade through the medium of the cap-plate. The block might intermesh directly with the cutting-blade, but preferably it does that through the medium of the cap-plate. If considerable adjustment of the blade is necessary in order to make it cut properly, the lever 18 may be turned as far as possible in the desired direction and then lifted, so that the lug 19 is disengaged from the slot 17 in the head of the screw 11. This will permit of the lever being moved in the opposite direction without moving the screw, and the operation may be repeated as much as desired until the proper adjustment is obtained. The blade-adjusting lever may be made to move the blade in either direction, and also it may itself be moved in either direction without moving the blade. Whenever the proper adjustment of the cutting-blade is approximately secured the lever 18 may be moved to the positions shown in Figs. 1 and 2 by simply disengaging the lug 19 from the slots 17 and moving it back to that position where it lies conveniently close to the handle of the plane, so that if a slight adjustment of the blade is desired at any time it may be effected by moving the lever in the desired direction by the finger or thumb and finger without moving the hand from the handle.

It is well known that heretofore the adjustment of the blade up and down has been accomplished by a lever, one end of which engages the blade and the other end of which is bifurcated and straddles a screw, which is turned by a thumb-nut. This well-known mechanism has decided disadvantages. For instance, the size of the head of the screw must be small, because of the small space allowed for it, and the pitch of the thread of the screw is such that it is very ditiicult to turn the screw with such a small head. Again, there is enough backlash in the old construction to cause considerable difficulty in obtaining an accurate adjustment of the adjusting device and cutting-blade. By the use of the lever in my device I have what is equivalent, in the plane illustrated in the drawings, of a four-inch wheel, with which to turn my adjusting-screw. This permits me to use a screw of such a pitch that the backlash is practically nothing. Another decided advantage which my arrangement has over the well-known screw is that the blade may be adjusted vertically without removing the hand from the handle, and a slight adjustment may be obtained by simply moving the lever by the thumb or finger in the desired direction. In the ordinary adjustment, which has been referred to above, it is necessary to remove the hand entirely from the handle in order to operate the screw, such an arrangement being not nearly as advantageous as mine.

In Figs. 7, 3, and 9 I have shown a modification in which the block 14 is not threaded, the screw 11 being threaded intoa lug 22 on the frog. The operation ot the device is substantially the same as that shown in the first six figures, with the exception that here the screw moves, while in the perferred form the screw is stationary as far as lengthwise movement is concerned.

I claim as my improvement —

1. In a plane, the combination with the cutting-blade, of a frog provided on its rear face with an apertured lug, an adjusting-screw mounted in the aperture of the said lug, a transversely-arranged screw in the said lug for securing the said adjusting-screw in position, a blade-adjusting block extending to the rear of the frog and in engagement with the said screw and secured at its forward end to the said blade, and means for rotating the said screw.

2. In a plane, the combination with the cutting-blade, of a frog rigidly secured in the plane and provided in its upper portion with a longitudinally-arranged slot, a lug formed integral with the said frog, said lug having a longitudinal slot, the rear side of which is open, an apertured block arranged in the said longitudinal slot, a screw extending through the openings in the said lug and block and means for rotating the said screw.

3. In a plane, the combination with the blade, of a frog having its upper end reduced in thickness and provided with an elongated slot therein, a lug formed integral with the said frog and provided with a longitudinal aperture extending inward from the rear side of the lug, a block slidably mounted in the slot of the frog, and having its inner end secured to the blade, an adjusting-screw mounted in the said lug and being in screw-threaded engagement with the said block, a transversely-arranged screw secured in the said lug, and a cap on the said screw, substantially as and for the purpose specified.

4. In a plane, the combination with the blade, of a frog provided in its upper end with an elongated slot, a block slidably mounted in the said slot and having its inner end secured to the blade, a lug formed integral with the said frog and provided with a longitudinal slot, an adjusting-screw having its lower end in screw-threaded engagement with the said block, and its upper end arranged in the aperture of the said lug, a head formed integral with the said screw and bearing on the lower face of the said lug, a collar formed integral with the screw and bearing on the upper face of the said lug, and means for adjusting the said screw.

5. In a plane the combination of a cutting-blade, an adjusting-screw provided with a notched head, means carried by said screw and engaging the blade, whereby the rotation ofthe screw adjusts the blade longitudinally, and a lever rotatably mounted on said screw and extending radially therefrom, said lever being free to tilt thereon to engage and disengage therewith to rotate it, substantially as described.

6. In a plane, the combination of a cutting-blade, an adjusting-screw provided with a notched head, means carried by said screw and engaging the blade whereby the rotation of the screw adjusts the screw longitudinally, a lever rotatably mounted on said screw and extending radially therefrom, and being free to tilt thereon to engage and disengage therewith to rotate it, and a spring to normally hold the lever in engagement with the screw.

7.

To all whom it may concern:

Be it known that I, MASCHIL D. CONVERSE, a citizen of the United States, residing at New York, borough of Manhattan, in the county and State of New York, have invented new and useful Improvements in Planes, of which the following is a specification.

My invention relates to improvements in planes, and more particularly to means for securing and adjusting the irons thereof; and the objects of my invention are to improve the efficiency of such and to simplify the construction and reduce the cost of manufacture.

My invention is comprised in certain novel mechanisms, construction, arrangement, and combinations of parts hereinafter fully set forth and claimed.

In the drawings, Figure 1 is a longitudinal vertical sectional elevation of a plane, of a type commonly known as “iron corrugated-bottom” planes, showing my invention incor-porated. Fig. 2 is a plan view of important parts of my invention, compassing the principal means for accomplishing vertical adjustment of the plane-iron. Fig. 3 is a plan view of the plane-iron and lateral-adjustment mechanism. Fig. 4 is a cross-section on line x x of Fig. 1; and Figs. 5 and 6 are views, partly sectional, illustratrating modilied constructions of my invention, all showing construction, application, and operation of my invention, as will be hereinafter more fully set forth in detail.

My invention may be applied to all types of planes, although I have shown it as applied to iron planes, as hereinbefore stated.

Planes have been made with mechanisms for vertical adjustment of the irons comprising bell-crank members and transverse grooves in the plane-irons to be engaged thereby pivoted to the body. Others have been made with mechanisms for vertical adjustment of the irons comprising bell-crank members and transverse slots in the plane-irons to be engaged thereby and pivoted to the body above the fulcrum-screw, and still others have been made with mechanisms for vertical adjustment of the irons comprising bell-crank members pivoted through the longitudinal slot of the plane-iron to a bed-piece at points above the fulcrum-screw and in engagement with notches in the cap-plate. Planes of such construction are expensive of manufacture, involving careful and accurate dimensioning of the throat and finishing of the ways and channels by difficult and tedious machining. In my present invention I overcome these disadvantages by novel arrangement and form of parts, dispensing entirely with the notches in the cap-plate and with the transverse grooves or slots in the plane-irons, rendering it wholly unnecessary to perform any expensive machining or fitting to compass a proper and accurate adjustment and holding of the plane-irons, all of which will be clearly seen and understood by those skilled in the art from the descriptions following.

Like letters indicate corresponding parts throughout the several figures.

A is the body of the plane, B a knob attached to the front portion thereof, and C the handle proper attached to the rearward portion.

D is a post and saddle-rest, which in case of iron-body planes is preferably cast integral centrally thereof. The apex of this post l prefer to make A-shaped, (distinctly shown at a, particularly in Fig. 4,) and the face thereof sloped to correspond with the incline b at its forward and broadened base c, the latter forming pivotal points and a rest for the extreme lower end of a vertical-adjustment lever d, which is pivoted thereto by a screw e. Upon the flattened upper surface of the pivoted end of the lever d rests the lower end of a flat saddle-plate f, which lower end is slotted longitudinally and recessed or countersunk on the upper side at g to receive the said pivot-screw e, which also serves to hold it in place, though admitting of a vertical sliding movement. Adjacent to the upper end of this saddle on the nether side a projection i is cast or formed, and a V-shaped groove h is formed therein to rest in slidable engagement with the sloping A-shaped apex a of the post D, which also serves to retain the same against lateral movement, a condition necessary for the carrying out of part of my invention. At a point centrally thereof and between the V-grooved projection i and above the slot g and pivot e is another opening in the saddle at j, the narrower lowermost end of which is recessed or countersunk on the under side at k to receive the head of the fulcrum screw or stud l when the same is slipped under the laterally-overhanging edges thereof. This fulcrum screw or stud l is secured in a clamping-plate m from its under side, (and I prefer to use a screw for convenience of adjustment.) In the upper end of the clamp-plate is a gnarled-head cramp-screw n, the rounded end of which engages a depression o of a lateral-adjustment lever p, serving as a pivot therefor. The vertical-adjustment lever d is provided at its upper end with a button q for operating. Midway of the ends and laterally of the slot g in the saddle f there is a hole r (see Fig. 2) for reception of a stud s, (freely fitting it, see same figure,) which stud is fixed (preferably rigidly) upon or in the vertical-adjustment lever d at a like position laterally relatively the axis thereof and pivot-screw e. This stud s and the hole r are located on a transverse line at right angles to the longitudinal vertical centers of the lever d and sliding saddle f, respectively, directly opposite the center of the pivot-screw e and sufficiently distant therefrom that it may not bind by describing an arc of too small a radius when the lever is operated.

For convenience and so that post D and projection i may not interfere therewith the lever d is open or divided at u and joined again above at the button q.

T is the plane iron or bit, which has a slot t longitudinally its center to admit of passage of the head and shank of the fulcrum-screw l therethrough.

In the modifications shown by Figs. 5 and 6 the principles of my invention hold, these modifications being such as render my invention applicable to what are known as “block-planes.” In the case of Fig. 5 the cramp-screw n5 is inverted and screw~socketed within and on the under side of the shell-like extension of the clamp-plate m5. The gnarled head of the screw being enlarged somewhat is accessible from the lateral sides, while in the case of Fig. 6 instead of a cramp-screw a projecting point n6 serves to engage the lateral-adjustment lever p6 as its pivot, and a gnarled head cramp-screw l6 is entered from the forward upper side through the clamp-plate m6 and engages a threaded hole k6 in the saddle f6.

The operation of my invention is as follows: To raise or lower the plane-iron T, push the button q to the left or right hand, which will cause the stud s to carry the saddle f up or down as the lever is rocked on its axis at e. To square the cutting end of the plane iron or bit with the throat of the plane, push the lever p to the right or left, as may be required, which causes the eccentric v to move the bit till the desired lateral adjustment is had. All these movements may be made without loosening the cramp-screw.

I do not limit myself to the specific form of the vertical-adjustment lever described herein, except that it should be located beneath the saddle f, which rests upon its lower end, and have its pivotal axis e and saddle-engaging stud s at its lowermost end or below the transverse plane of the fulcrum-screw and the apex of the post D, nor do I limit myself to the particular form of the post or of the saddle herein described, as manifestly they may be modified without departing from the spirit of my invention.

It will be readily understood by those skilled in the art that the novel construction and arrangement of the parts in my present invention, as well as their simplicity, make it possible to cast the same in metal to substantially finished form and dimensions, excepting the screws, thus saving the laborand cost of fitting.

I do not herein claim the lateral-adjustment mechanism shown, except in combination with the leading features of my present invention, for the reason that the same was allowed to me broadly by Letters Patent of the United States No. 619,394, dated February 14, 1899; but,

Having described my invention, what I do claim as new, and desire to secure by Letters Patent, is —

1. In a plane a vertical-adjustment mechanism comprising a laterally-movable lever pivoted centrally to the plane-body at a point below the transverse plane of the fulcrum-screw and of the apex of the post; a stud located thereon on the top side and laterally opposite its axis, a saddle engaged by said stud held in place by the pivot-screw of said lever, and slidably resting upon the pivoted end of the same and upon the apex of a post above said fulcrum-screw, in combination with a plane-iron and means for clamping the latter upon said saddle.

2. In a plane a laterally-movable lever pivoted centrally to the plane-body at a point below the transverse plane of the fulcrum-screw and of the apex of the post; a stud located thereon on the outer side and laterally opposite its axis; a saddle engaged by said stud held in place by the pivot-screw of said lever and slidably resting upon the pivoted end of the same and upon the apex of a post, above said fulcrum-screw; a plane-iron and means for clamping the same upon said saddle, in combination with mechanism for lateral adjustment of the plane-irons.

3. In a plane a vertical-adjustment mechanism comprising a laterally-movable lever pivoted centrally to the plane-body at a point below the transverse plane of the fulcrum-screw and of the apex of the post; a saddle slidably resting upon the pivoted end of said lever and upon the apex of a post; a laterally-located stud operatively connecting said saddle and said lever below the transverse plane of the fulcrum-screw, and a plane-iron, in combination with a lateral-adjustment lever eccentrically pivoted at the upper end of a clamp-plate.

4. In a plane a vertical-adjustment mechanism comprising a laterally-movable lever pivoted at its lower end; a saddle slidably resting upon the pivoted end of said lever and upon the apex of a post removed from the pivoted end of said lever, in combination with means for operatively connecting said lever and said saddle at their respective lower ends to accomplish vertical movement of the latter.

5. In a plane a laterally-movable pivoted vertical-adjustment lever, having an opening u centrally thereof, in combination with a saddle operatively engaged by said lever and having a groove h longitudinally central thereof on its under side contacting with the apex of a central post D within the plane-body and held in place by the pivotal screw of the lever.

6. In a plane a laterally-movable pivoted vertical-adjustment lever, having an opening fa centrally thereof, in combination with a post D projecting within said opening.

To all whom it may concern:

Be it known that I, LEWIS M. CURRY, a citizen of the United States of America, residing at Brighton, in the county of Livingston and State of Michigan, have invented certain new and useful Improvements in Planes, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to improvements in carpenters’ planes; and its object is to provide a cheap and simple construction which is strong and durable, having few parts, easily assembled, and not liable to get out of order, and to provide ready means for accurately adjusting the plane-bit longitudinally within the throat and to so construct the parts as to allow for a slight lateral adjustment of the bit, it also being the object of this invention to provide means for clamping the bit and its shavings-breaker to the support therefor, so that they are firmly held without the necessity of a clamping-plate or other obstruction on the upper side of the breaker, and the bit will be frictionally held against accidental lateral movement thereby, but may be so adjusted by the operator.

To this end the invention consists in providing a longitudinally-movable carrier for the bit, which carrier is supported at an inclination substantially the same as that of the bed and free to move laterally on its support, and in providing suitable means for securing the bit to the carrier at one end, which means also serves to hold the lower end of the bit in strong frictional contact with the bed to prevent such lateral movement of the bit except when adjusted by the operator; and the invention further consists in providing suitable mechanism for moving the carrier and attached bit longitudinally to regulate the cut, and also in the particular construction, arrangement, and combination of parts, all as more fully hereinafter described, reference being had to the accompanying drawings, in which —

Figure l is a perspective view of a device embodying my invention; Fig. 2, a longitudinal vertical section through the bit and adjacent parts and a portion of the stock on the line 2 2 of Fig. 3. Fig. 3 is a section on the 2, showing a plan view of the line 3 3 of Fig. 2; Fig. 4, a section on the line 4 4 of Fig. 2, showing the carrier in plan; Fig. 5, the same, showing the carrier in section and illustrating the manner in which the bit is adjusted laterally; and Fig. 6 is a longitudinal vertical section similar to Fig. 2, showing a modified adjustment for the carrier and showing the bit unclamped to illustrate the manner in which it is held against the bed.

A is the stock of the plane, formed, in the usual manner, of hard wood, with a throat A’, having the mouth A2, and one side extended at an inclination of about forty-five degrees to form the bed A3, upon which the bit-iron or knife rests.

B is a casting secured to the top of the stock and provided with upwardly-extended supporting flanges or sides B’, which form bearings for the transverse pin C and eccentric-rod D, which support the bit-carrier E. Said carrier E consists of a rectangular casting having its middle portion cut away to lighten the same and provided with a lug E’, projecting from its lower end, which lug has an elongated opening E2 or slot through which the pin C extends, and through a transverse opening E3, near its upper end, extends the eccentric-rod D, which rod is provided with bearing ends D’ and D2 to engage the bearings in said sides B’. The rod D is set eccentrically to its bearing ends, so that when the same is turned by the knurled head D3, which is secured on the outer end of the reduced portion D4, the carrier will be moved a distance equal to the throw of said eccentric, and to secure the eccentric in place and connect the sides B’ a yoke F is provided, which embraces the sides B’ and is secured at its lower ends by the pin C, which extends therethrough and is riveted at its outer ends and near the top of the sides by the screws F’, said yoke extending over and closing the outer end of the opening forming the bearing for the end D’ of the eccentric and has an opening to at the reduced portion D4, thus securing the eccentric in place and forming a brace for the sides B’.

The knife or bit-iron G and its cap-iron or shavings-breaker H are secured together in the usual manner by a set-screw H’ engaging a slot G’ in the bit. The breaker is nearly as long as the bit and is provided with openings H2, having lateral extensions H3, located opposite the slot G’, to receive the heads of the screws I and J, which screws engage screw-threaded openings I’ and J’ in the carrier E, the head of the screw I forming an abutment to engage the upper side of the breaker.

The carrier E is supported at substantially the same inclination as the inclination of the bed A3, and the screw I is adjusted to bring its head at such a height relative to the bed that when said head is passed through the openings H2 and the breaker moved to engage the extension H3 with the shank of the screw the lower end of the bit will engage the bed adjacent to the mouth.

A binding-screw K engages a screw-threaded opening K’ in the carrier E, and on the inner end of said screw is a head K2, a recess K3 being provided in said carrier for said head, which head is forced upward by the turning of the screw into engagement with the under side of the bit and forces the lower end of the bit against the bed, the screw J being properly adjusted relative to the screw I to form a stop to prevent the bit from being bent too far by the action of the screw. The turning of the binding-screw K thus not only secures the bit to the carrier, but forces the same into frictional contact with the bed by the spring of the said bit, and by adjusting the screws I and J the frictional contact may be increased or diminished and the angle of the bit changed, so that it will lie flat upon the bed or will contact the same only at its lower end.

The carrier is made somewhat narrower than the space between the sides B’, and the eccentric is made to have a little play in its bearings, so that said carrier may be shifted laterally. When the bit is in place, the frictional contact thereof with the bed will hold the lower end of the bit so that when the upper end of the carrier is shifted the bit will be tilted to bring its cutting edge even with the sole of the stock when the bit is not ground exactly true, as shown in Fig. 5, and the spring action of the bit and its breaker causes a friction on the eccentric D, so that it will not be accidentally turned.

If desired, an adjusting-screw L, passing through an opening in the yoke F and engaging screw-threaded openings in the carrier, may be provided to move the carrier instead of the eccentric D; but I prefer said eccentric, as it is more accurate, is simple, cheap, and more durable.

Having thus fully described my invention, what I claim is —

1. In a plane, the combination with the stock; of side flanges on said stock, a bit, a movable carrier to which the bit is secured, and means supported by said flanges for supporting and moving the carrier to adjust the bit.

2. In a plane, the combination with the stock; of side flanges on said stock, a laterally-movable bit-carrier, a bit secured to said carrier, and means on the flanges for supporting the carrier and upon which it may be moved laterally of the stock to tilt the bit.

3. In a plane, the combination with the stock; of side flanges on said stock, a bit-carrier supported by said flanges and adapted to be moved laterally between the same, a bit on said carrier, and means for securing said bit to the carrier and for causing a frictional resistance to such lateral movement of the carrier.

4. In a plane, the combination with the stock; of a bit adapted to be moved longitudinally, side flanges on said stock and an eccentric supported by said flanges and adapted to move said bit.

5. In a plane, the combination with the stock thereof having a bed; of a carrier supported upon said stock and provided with screw-threaded openings a bit having an opening and engaging said bed at one end, a screw engaging one of the openings in the carrier and projecting through said opening in the bit to engage its head with the upper side of said bit, and a binding-screw engaging the other opening in the carrier and contacting the under side of said bit.

6. In a plane, the combination with the stock and a bit thereof; of supporting-flanges on said stock, a carrier to which the bit is secured, supported by said flanges to move longitudinally and provided with a transverse opening, and an eccentric within said opening.

7. In a plane, the combination with the stock thereof; of supporting-flanges on said stock, a carrier having a slot and a transverse opening, a pin supported by the flanges and engaging said slot, a rod in said opening having eccentric ends engaging bearings in said flanges, a bit, and means for securing said bit to said carrier.

8. In a plane, in combination a stock having a bed, supporting-flanges on said stock, a carrier having a slot at its lower end and a transverse opening near its upper end and screw-threaded openings, a pin secured at its ends to the supporting-flanges and extended through said slot, a rod in the transverse opening and having eccentric ends engaging bearings in the flanges, and provided with a head, a bit having openings, screws having heads projecting through said openings and engaging the upper side of the bit and adjustable in the screw-threaded openings in the carrier, a binding-screw extending through said carrier and a head on said binding-screw engaging said bit.

9. In a plane, the combination of a stock a casing secured to the upper side of said stock, the supporting-flanges on said casings having openings, a longitudinaily-movable carrier having a slot and a transverse opening, a pin extending through the opening in the flanges and the slot in the carrier, a rod engaging the transverse opening in the carrier and provided with eccentric ends engaging bearings in said flanges and having a reduced portion provided with a knurled head, a yoke embracing the flanges and provided with an opening to receive the reduced portion of the eccentric, and a bit secured to said carrier.

In testimony whereof I affix my signature in presence of two witnesses.

To all whom it may concern:

Be it known that I, EDWARD S. MARKS, a citizen of the United States, and a resident of the city of Auburn, in the State of New York, have invented certain new and useful Improvements in Planes, of which the following is a specification.

This invention relates to the devices by which the chisel is adjusted in relation to the plane-stock; and it consists in certain new constructions and arrangements of the parts by which this adjustment is effected.

In the drawings, Figure 1 is a plan of a plane-stock provided with my improvements. Fig. 2 is a vertical section upon the line x y of Fig. 1, and Fig. 3 shows the lever separately.

Similar reference-letters indicate like parts in the several views.

In the drawings, A is the plane-stock. B is the chisel, which is secured by means of the cap C, which is held by the screw D and is locked by means of the lever E, pivoted at e and carrying a cam e’.

The foregoing parts are of usual construction.

Upon the plane-stock a carriage F is pivoted at f, which oscillates in the horizontal plane across the bed g. The carriage F is furnished with a slide h, seated thereon, and actuated by a screw K, which extends to the rear of the carriage F and is turned by its head L. A projection n upon the slide h, engages a corresponding depression or aperture m, in the chisel and holds the latter in position.

In operation the lengthwise adjustment of the chisel is performed by rotating the screw K, and by moving the carriage F upon its pivot f crosswise the lateral adjustment of the chisel is effected.

Wliat I claim as new, and desire to secure by Letters Patent, is —

In a plane and in combination; a plane-stock; a chisel mounted therein; means for clamping said chisel in said stock; a carriage pivotally mounted on said plane-stock so as to permit a lateral adjustment of said carriage and the parts supported thereby; a slide mounted on said pivoted carriage, and engaging said chisel ; and means carried by said carriage to adjust said slide and chisel longitudinally.

Be it known that I, EDWARD S. MARKS, a citizen of the United States, and a resident of the city of Auburn, in the county of Cayuga and State of New York, have invented certain new and useful Improvements in Planes, of which the following is a specification.

This invention consists in certain new devices used to regulate the position of the chisel in relation to the plane-stock; and its object. is to furnish means for readily adjusting the chisel both longitudinally and laterally.

In the drawings, Figure 1 is a plan of a plane provided with my improvements and with the chisel and retaining-cap removed; and Fig. 2 is a sectional view upon the line x y of Fig. 1, showing the chisel and cap in position.

Similar reference-letters indicate like parts in both views.

In the drawings, A is the plane-stock, B is the chisel, and C the cap-iron, which is secured under the cross-bar D by means of the screw E.

The chisel B is provided with a rack b, and a pinion-section d, pivoted at f and operated by a lever K, engages it. The dotted lines of Fig. 2 indicate different positions which this lever may occupy in the vertical plane. By this means the chisel is moved in the direction of its length as required.

The carriage g, which supports the pivot f, is pivotally secured at h, so that it may be moved laterally, and the dotted lines of Fig. 1 show dilierent positions which it may occupy in the horizontal plane, the upright ears g’, rising from the carriage g, straddling the rack b on the under side of the chisel B and lengaging the parts for lateral adjustment, as shown in Fig. 2, the segment m upon the plane-stock furnishing a support for it in its different positions.

By the above-described means the chisel B is readily adjusted either vertically or laterally, as desired.

What I claim as new, and desire to secure by Letters Patent, is —

1. In a plane and in combination, a plane-stock, a chisel, means for clamping said chisel in said plane-stock, a carriage having a vertical pivotal connection with said plane-stock, a lever carried by and having a horizontal pivotal connection with said carriage to shift said carriage laterally on its pivot, means on said carriage to engage and shift said chisel laterally, and means on said pivoted carriage-lever to engage said chisel and shift it longitudinally.

To all whom it may concern:

Be it known that I, MASCHIL D. CONVERSE, a citizen of the United States, residing in the city of New York, borough of Manhattan, county of New York, and State of New York, have invented certain new and useful Improvements in Planes, of which the following is a specification.

My invention relates to planes, and more particularly to adjustment mechanisms for the bits or irons thereof.

In planes constructed with clamp-plates and cramp-screws for securing the bit, more especially in those in which the end of the cramp-screw engages the surface of the bit, of which Letters Patent No. 619,394 is an example, it has been found that the point or end of the cramp-screw so indents and mars the surface of the bit that when it is desired to loosen the latter for adjustment the marred surface frequently interferes by either requiring the said cramp-screw to be so much loosened (to free the point or end of the indentations) that efforts to adjust the bit in one direction (either longitudinally or laterally) will cause the other adjustment to be lost or when retightening the cramp-screw its end will slip back again into the indentation or marrings on the bit’s surface, so that the desired adjustment is not with facility and certainty attained.

The objects of my present invention are not only to overcome these difficulties, but to provide a lateral adjustment mechanism which shall be adapted for use also in convertible planes of the type shown in Letters Patent No. 620,226 or analogous ones in which clamp-plates and cramp-screws essentially of the same character as hereinbefore referred to are employed, but in which the end of the cramp-screw instead of engaging the surface of the bit engages a slide or a socket in a slide, and the further object is to provide an inexpensive, simple, and efficient lateral adjustment device that may be expeditiously operated.

To these ends my invention consists in the several particulars of construction, arrangement, and combination of parts severally and more particularly hereinafter pointed out and claimed.

In the drawings, Figure 1 is a side elevation, partly sectional longitudinally, showing my invention as applied in planes of the herein-above first-mentioned type. Fig. 2 is a nether side view of the plane bit or iron, clamp-plate, and my invention removed from the stock, further showing the application and construction of certain parts thereof. Fig. 3 is a side elevation, partly sectional longitudinally, of the hereinabove second-mentioned type, showing the application of my invention to the same. Fig. 4 is a side elevation, partly sectional longitudinally, of one modiiied construction of my invention, sometimes desirable in applying it to this second-mentioned type of planes; and Fig. 5 is a side elevation, partly sectional longitudinally, showing a further-modified application of my invention to this type of planes. These several figures will now be more fully described in detail.

Like letters and the same primed indicate corresponding parts throughout the respective figures.

A in Fig. 1 is the stock of a plane of the hereinabove first-mentioned type, having the usual handle B and knob C and provided with a post D, centrally upon which is mounted obliquely a longitudinally-movable plate E, forming the bed for the bit G, above which is another plate H, also longitudinally movable, which latter I construct with an arch a (said arch being one feature of my present invention) and provide with a cramp-screw J, which passes from the upper side through the outer portion at substantially right angles to its longitudinal plane.

I is a worm-screw (provided with a lever l and pivoted to the post D) to engage a rack K on the under side of the nether clamp-plate or bed E, making a known device for longitudinal adjustment of the bit.

L in Figs. 1 and 2 is a longitudinal slot in the bit having equal dimensions transversely throughout its extent. M in the same figures is a concave-convex thumb-wheel, preferably gnarled or milled on its extreme upturned periphery, having a hole through its axis for reception of the reduced portion or end of the cramp-screw (which latter is made with a shoulder N, as in Figs. 1, 3, and 5) or for the reception of the journal e, as in Fig. 4. This thumb-wheel is provided with an eccentric O, (which I prefer to be integral,) extending from the convex side to enter the slot L and engage the lateral parallel walls thereof. The diameter of this eccentric should be so nearly equal the transverse measurement of the slot L as barely to slide freely therein. The surface immediately surrounding the eccentric radially on the convex side of the thumb-wheel at P, I level or flatten in order that the same may have a considerable area for engagement with the upper side of the plane-bit G by overhanging the lateral margins of the slot L. The arch ct of the clamp-plate H is for the accommodation of the upturned periphery of the thumb-wheel, which latter is so made in order that it may be accessible to the thumb and finger of the operator.

At Q it will be seen that the hole in the axis of the thumb-wheel on the convex side is countersunk and that a portion of the reduced pivot or pivot end is upset at b, so as to prevent the said thumb-wheel from becoming separated from the clamp-plate H when the bit is being removed.

Those skilled in the art will now see that in the operation of my invention the upturned periphery of the thumb-wheel gives convenient access (as before stated) for its manipulation by the thumb and finger of the operator, a construction for the thumb-wheel made possible when placed below the clamp-plate H by the arch a of the latter, that turning the thumb-wheel to either the right or left will accomplish lateral adjustment of the bit, and that the overhanging radially-extended flattened surface of the convex side of the thumb-wheel at P offers an area of sufficient extent to prevent indentation or marring of the surface of the bit, which it engages when the cramp-screw J is tightened, and because the point or end of the cramp-screw is not employed to engage the bit, but its pressure is communicated to the latter by means of the shoulder N, through the thumb-wheel, the under or convex side of which latter bears upon and binds the bit, except in the modification shown by Fig. 4, where the journal or pivot of the thumb-wheel and eccentric is independent of the cramp-screw and is not axially coincident therewith, which cramp-screw, however, in such case does not engage the surface of the bit, but engages a slide or a socket in a slide, as before mentioned, while in the modification shown by Fig. 5 a stud S is fixed in the clamp-plate to engage the socket in the slide (but without pressure on the bottom of the socket) instead of the cramp-screw. The advantages of the device of an arched clamp-plate H, with a thumb-wheel of the form described, will also be readily seen by such both on account of great economy of manufacture (since they severally may be cast in integral parts) and greater efficiency and convenience in operation.

I do not herein claim, broadly, the application of a lateral bit-adjustment mechanism to have its fulcrum coincident to the axis of the cramp-screw, such having been claimed and allowed to me in Letters Patent No. 619,394, dated February 14, 1899, nor do I wish to limit myself in my present invention to a combination with the cramp-screw as a pivotal axis therefor, since manifestly the improved form and construction of the leading features of my present invention adapt it to be employed on an independent pivot similarly to that shown in Fig. 4.

Having described my invention, what I do claim as new, and desire to secure by Letters Patent, is —

1. In a plane a lateral bit-adjustment mechanism comprising an arched clamp-plate carrying a pivot and cramp-screw, a concavo-convex thumb-wheel revolubly mounted on said pivot, provided with an eccentric on its convex side and a radially-flattened surface thereon adjacent to said eccentric, in combination with a longitudinally-slotted bit.

2. In a plane a lateral bit-adjustment mechanism comprising an arched clamp-plate carrying a shouldered pivot and cramp-screw, a concavo-convex thumb-wheel revolubly mounted on said pivot, provided with an eccentric on its convex side and a radially-flattened surface thereon adjacent to said eccentric, in combination with a longitudinally-slotted bit.

3. In a plane a lateral bit-adjustment mechanism comprising an arched clamp-plate carrying a pivot and cramp-screw, a concave-convex thumb-wheel revolubly mounted on said pivot, provided with an eccentric on its convex side and a radially-flattened surface thereon adjacent to said eccentric and means for preventing the said thumb-wheel from becoming accidentally detached from said clamp-plate, in combination with a longitudinally-slotted bit.

In testimony whereof I afiix my signature in presence of two witnesses.

To all whom it may concern:

Be it known that I, JUSTUS A. TRAUT, a citizen of the United States, residing in New Britain, in the county of Hartford and State of Connecticut, have invented certain new and useful Improvements in Planes, of which the following is a specification.

This invention relates to planes, and especially to knife-adjusting means therefor; and it has for its main object the provision of an improved tool of this type in which the knife can be set quickly in an adjusted position and held firmly in place without the use of adjusting-levers, the construction being such that all of the parts can be separated and assembled with great rapidity and precision.

My present improvements are designed more particularly for use in connection with planes of that type in which the knife or plane-bit is disposed at a comparatively-small angle with respect to the sole of the plane, thereby leaving but a small space at the rear end or heel of the plane for the knife adjusting and holding devices, and it is of the utmost importance in tools of this kind to provide holding and adjusting means which may be assembled and disassembled readily and operated a minimum distance for the purpose of effecting the proper adjustment of the plane-knife. It is essential, of course, that all of these parts should be so organized that the knife will be held firmly in place when set in any adjusted position, or else the adjustment of the bit might be changed and the proper operation of the tool prevented.

In the plane illustrated in the drawings of this application I have illustrated devices for obtaining two different adjustments of the plane knife or bit — one a rough adjustment, by means of which the knife may be brought quickly approximately to its proper position, and a fine adjustment, which will be effected, preferably, by means of a suitable adjusting-screw.

The device which I employ for obtaining the fine adjustment of the plane-bit constitutes one of the main features of this invention, and I may employ for this purpose an adjusting-screw having two diderent threads thereon, one of which coacts with a suitable member of the plane-bit and the other with the knife or its carrier. In this instance the knife is supported on a slide which will have a supporting-face oblique to the sole of the plane and will be shifted toward and from such sole by means of an adjusting-screw of the kind just described. Preferably the adjusting-screw will have two similar threads of different pitch, one of which will engage a fixed member of the body of the plane and the other of which will engage the slide, the parts being so organized that when the screw is turned it will move in the same direction through both the slide and the supporting member of the plane-bit and will at the same time cause the slide to be shifted toward and from such supporting member in accordance with the direction of movement of the screw.

The screw which I employ will be of two diameters in order that the smaller diameter thereof, which is at the point, may admit of the insertion of the reduced part through a proper threaded opening or fixed nut in the plane-bit; but the threads of the portion of the screw which is of larger diameter engage the corresponding internal threads of the member or fixed nut on the body of the plane. Hence it will be evident that in assembling the parts the reduced end of the screw may be passed through the threaded member of the plane-body and the point of the screw then inserted in the proper threaded opening or fixed nut of the slide, whereupon the screw may be turned into the two parts simultaneously by the turning of two similar threads of different pitch in the same direction, and thus draw the slide toward the supporting member of the plane-body while the screw is advancing through the threaded member or fixed nut of the latter. It will be noticed that this movement of the slide toward the fixed member on the body is due to the fact that the thread at the forward end of the screw is of quicker pitch than that near the head of the screw.

For the purpose of effecting the coarse adjustment of the plane-knife said knife and its support will have coacting holding members, one of the parts having a single holding member and the other a series, although each of the members of said series is adapted to engage said single holding member, so as to lock the plane-knife roughly in any desired position with respect to the throat of the plane. Usually the knife-support, which in this case will be the slide, will have a stop or rib projecting therefrom and adapted to enter any one of a longitudinal series of recesses in the plane-bit, these recesses being preferably in the form of parallel transverse grooves in the under side of the knife. It will be clear that these coacting holding means will permit a rough adjustment of the knife approximately in the desired position and that the fine adjustment may be effected afterward by means of the screw. Moreover, when the knife has such a row of recesses or grooves therein as that just described it will be apparent that the knife may be used in connection with planes of several different sizes, which is a matter of considerable importance.

In the drawings accompanying and forming part of this specification, Figure 1 is a sectional side elevation of a plane constructed in accordance with my present improvements. Fig. 2 is a transverse section of the plane-body and the slide, the section being taken in the line 2 2, Fig. 1, looking toward the heel of the plane. Fig. 3 is a perspective view of the knife supporting and adjusting slide, and Fig. 4 is a perspective view of the rear end or heel of the plane-body and illustrates the supporting member or guide on which the knife-adjusting slide is mounted.

Similar characters designate like parts in all the figures of the drawings.

As to many of the features thereof the body of the plane illustrated herein is similar to plane-bodies as ordinarily constructed. In this case the plane-body (designated in a general way by B) embodies as its essential features a flat base or sole s, side walls 2 2, and a support or guide, such as g, on which the slide will be carried. This guide may be of any suitable construction and is substantially U-shaped in this case in horizontal section and has a pair of oblique supporting-faces 3 3, on which the slide may move. At the inner side of the two side walls 4 4 of the guide I have illustrated a pair of channels or grooves 5 5, forming, with the oblique faces 3 3,ways for locating and guiding the slide.

As before stated, the knife or plane bit is intended to be supported on a slide shiftable by means of a feed-screw in order to obtain the fine adjustment of the knife, and this slide is indicated by S. It may be of any suitable construction, but in this case will have a pair of channels or grooves 6 6 in the under side of the main or fiat portion 7 thereof, these grooves being parallel to each other and so disposed as to cooperate with the guide-faces 3 3 and the grooves 5 5, as will be evident by referring to Fig. 2. It will be clear that this slide moves on the ways of the guide g toward and from the sole of the plane in a path oblique to such sole, this method of mounting the slide being well understood.

For the purpose of shifting the slide in the manner described I have illustrated at f 2 feed-screw of the type which has been hereinbefore referred to, the body portion of this screw being of two diameters and one portion having right-hand threads of one pitch and the other having corresponding threads of a different pitch. In this case it will be clear that the threads 10 are of a relatively-slow pitch, while the threads 12 are of somewhat-quicker pitch, and hence will be capable of shifting the slide with which they codperate so as to move said slide toward and from the back wall 13 of the guide g, in which back wall the feed-screw is mounted so as to lie obliquely to the sole s. The wall 13 of the guide is bored and screw-threaded to correspond with the threads 10 and form a fixed nut, in which the larger portion of the screw may work, while the slide S will have in this case a fixed nut in the form of a depending lug 14, internally screw-threaded to cooperate with the threads 12 of the point of the screw f. When the parts are properly fitted, the slide S may be shifted longitudinally of the slide-supporting faces of the guide, but will be held down and will be prevented from rising by reason of its connection with the screw f, which is braced firmly, and will be supported by the guide in such a manner that it will have no movement except in the direction of its length.

In assembling the parts the feed-screw, which will usually have a milled head, such as 15, of relatively-large diameter for the purpose of turning the screw freely, will be inserted through the opening 13′ until the threads 10 come into engagement with the threads of such opening, and the point of the screw will then be inserted into the opening 14′ in the fixed nut of the slide from the rear side thereof when the slide is in its extreme forward position on the ways of the guide. When the screw is turned to the right, the threads 10 will turn forward and the feed-screw will gradually pass through the opening 13’ toward the throat of the plane, and at the same time the threads 12 will turn forward in the fixed lug 14 of the slide and by reason of their quicker pitch will cause the slide to shift toward the wall 13. It will be seen that by employing a feed-screw of this type the assembling of the slide, the feed-screw, and the plane-body will be effected with a minimum movement of the slide on the guide g, since the screw advances into both of the fixed nuts in the same direction and does not, as is the case with a right and left hand screw, have to be inserted into one side of one nut and into the other side of the other nut. Hence the slide can be put in place approximately in its proper position, and its screw then turned into both of the fixed nuts a relatively-slight distance to position properly the knife to be supported and adjusted by the slide. This form of feed-screw and cooperating fixed nuts and the manner of assembling the parts described are of distinct utility, especially in those planes of the type illustrated herein having their knives set at a very slight angle to the sole, leaving but a small amount of available space between the rear end of the knife and the heel of the plane. By employing the devices shown herein this space is utilized to the best advantage, and all of the parts are of ample size and strength to operate properly and hold the bit firmly.

The plane knife or bit is indicated by k and may be of any suitably type. This knife and the slide S are intended to have coacting holding members, such as those hereinbefore described, for effecting the coarse adjustment of the bit. The holding member of the slide is indicated at 16 and is in the form of a stop or rib rising from a central wall or larger rib 17 of the slide S, the face 17′ of this wall or rib constituting the supporting-face on which the upper or rear end of the knife is carried. The other holding members, which cooperate with the stop or rib 16, are carried by the knife k and in the construction shown are in the form of a series of recesses or parallel transverse grooves 18 in the under side of said knife, these grooves forming between them transverse stops or ribs substantially similar to the ribs 16, the groove 18 being just large enough to receive the rib 16 and leave no extra space.

It will be clear that after the slide and its feed-screw are in place on the plane-body a rough adjustment of the knife may be obtained by simply placing the proper groove 18 over the stop 16 and placing the knife down upon the supporting-face 17′ of the guide. After this coarse adjustment is obtained the knife should of course be clamped firmly to the slide S, after which the adjusting-screw f may be turned to effect the fine adjustment of the knife.

Any suitable clamping means may be employed for holding the knife in place. That shown herein is indicated in a general way only and will preferably be of the type fully shown and described in Letters Patent No. 591,663, dated October 12, 1897. This main clamping device is in the form of a cam-lever (indicated by 20) carried by a knife clamp or plate c of ordinary construction, this latter being mounted at its forward end on a fixed part, such as 22, of the plane-body by means of a screw-and-slot connection, such as 23, of the usual type. This screw 23 serves to prevent sidewise movement of the forward end of the knife, while the cam-lever by raising the rear end of the knife-clamp c wedges the rear end of the clamp and the knife together and also forces the forward end of the clamp against the knife near the throat of the plane to hold the parts firmly in place.

After the rough adjustment of the bit has been obtained and the latter has been clamped in place by the means just described the screw f will be turned to obtain the iine adjustment of the knife, and it will be noticed that during this last-mentioned adjustment the part which operates directly to effect such adjustment of the bit is not only movable, but supports the knife directly and guides it, thus rendering unnecessary the employment of other or separate means for such purpose.

Having described my invention, I claim —

1. In a plane, the combination, with a plane-body comprising a sole and a pair of side walls, said sole having rigid with the inner face thereof a U -shaped slide-supporting guide the side walls of which extend in parallelism with the body side walls and have their upper edges inclined and recessed to form ways, and connected at their outer ends by an end wall having an internally-threaded opening; a slide mounted on said guide and recessed at its edges to cooperate with said ways, and provided at its under side with an internally-threaded depending lug working intermediate said side walls and on its upper side with a longitudinally-extending centrally-located rib having a transversely-extending rib or projection; a knife adapted to be clamped on said rib and provided with a plurality of transversely-extending recesses for the reception of said transverse rib to locate the knife in position; an adjusting-screw of different diameters working in said guide and slide and having two sets of similar threads of different pitch; and means for clamping the knife in position on said slide.

2. In a plane, the combination, with a plane-body comprising a sole and a pair of side walls, said sole having rigid with the inner face thereof a slide-supporting guide the side walls of which extend in parallelism with the body side walls and have their upper edges inclined, and which walls support at their outer ends a member having an internally-threaded opening; a slide mounted on said guide and provided at its under side with an internally-threaded depending lug working intermediate said side walls and on its upper side with a longitudinally-extending centrally-located rib; a knife adapted to be clamped on said rib, said knife and rib having, one a projection, and the other recesses cooperating with said projection to locate said knife in position; an adjusting-screw of different diameters working in said guide and slide and having two sets of similar threads of diderent pitch; and means for clamping the knife in position on said slide.

_________________

To all whom it may concern:

Be it known that I, ABRAHAM W. STAUFFER, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a certain new and useful Improvement in Carpenters’ Planes, of which the following is a specification.

My invention relates to a new and useful improvement in carpenters’ planes, and has for its object to provide a simple and effective means for adjusting the blade of the plane either up and down or sidewise and for clamping and holding the blade firmly in position.

With these ends in view this invention consists in the details of construction and combination of elements hereinafter set forth and then specifically designated by the claims.

In order that those skilled in the art to which this invention appertains may understand how to make and use the same, the construction and operation will now be described in detail, referring to the accompanying drawings, forming a part of this specification, in which —

Figure 1 is a side view of the plane having my improvements embodied therein; Fig. 2, a plan view thereof; Fig. 3, an enlarged section of a portion of the stock of the plane, showing my improvements in section and in position; Fig. 4, a detail view of the bed-block removed from the stock and showing the device for adjusting the bit; Fig. 5, a similar view of the back of the bit; Fig. 6, a section at the line y y of Fig. 4; Fig. 7, a detail view of the clamping-bar, and Fig. 8 represents the clamping-screw.

In carrying out my invention as here embodied, A represents the plane-stock, having fitted therein the bed-block B, which is adjustably secured within the throat of the plane by means of suitable screws passing through the slots C and into the stock. The upper surface of the bed-block is recessed, as shown at D, so as to receive the adjusting-lever E, which has a fulcrum extension F, upon which this lever rocks when being manipulated, said extension fitting within the recess G, formed for that purpose. The adjusting-lever has a hole H formed therein, which registers with the elongated hole I, formed in the bed-block, and through these two holes passes the clamping-screw J, the latter being threaded into the clamp-plate K. This plate is adapted to fit upon the upper surface of the bit L when the latter is in position upon the bed-block, forming a cap therefor, and the clamping-screw J passes through the slot M, formed in the bit, the upper end of which slot is enlarged, as at N , in order that the head of the screw may be withdrawn from the bit. A washer O is placed around the screw and bears against the under side of the bit, and a bushing P is interposed between this washer and the head of the screw in order that when the said screw is run into the clamp-plate the washer will be firmly bound against the under side of the bit, while the clamp-plate will be as firmly bound against the upper surface of the bit, thus tightly securing these parts together. When not assembled, the washer lies within the hole H in the adjusting-lever, permitting the latter to swing thereon.

Q is the clamping-bar, slotted at its lower end, as indicated at R, so as to embrace the screw and bushing thereon and be adapted to draw downward upon the head of said screw. This bar has a ridge S thereon, which acts as a fulcrum, bearing against the under side of the bed-block, so that when the outer end of the bar is forced upward, as hereinafter set forth, the lower end will be swung downward, as will be readily understood, thereby drawing with it the clamping-screw, and consequently the clamp-plate and bit. This action will force the bit firmly against the bed-block, thus holding it against any movement while the plane is in use. A plate-spring T is secured to the under side of the clamping-bar, so as to hold the latter in position and yet permit its movements when being operated to bring about the above-named results.

In order that the outer end of the clamping-bar may be drawn upward with sufficient force to accomplish the results aimed at, a thumb-screw U is passed through the slot V, formed in the bar and threaded in the bed-block, as clearly shown in Fig. 3, and, as is obvious, when this screw is run upon the bed-block it will draw the outer end of the bar upward, the purpose of the slot being to permit the withdrawal of the clamping-bar from the stock when it is desired to release the clamping-screw, and thereby permit the removal of the bit and parts carried thereby.

The upper portion of the bed-block is slotted, as shown at W, and through this slot passes a thumb-screw X, its inner end being threaded into the adjusting-lever E, so that when said lever has been swung to the position which properly adjusts the bit it may be there held by properly manipulating this thumb-screw.

While the bit under ordinary conditions will be held in its adjustment by the clamp-plate, the use of the screw X to hold the adjusting-lever will permit said lever also to act as a means for holding the bit in its adjustment, since so long as the adjusting-lever is held against movement the bit cannot have any lengthwise movement on account of the washer O fitting snugly within the hole H.

The means which I provide for the sidewise adjustment of the bit, which enables the cutting edge of the latter to be properly trued up, is as follows: A cross-slide Y is fitted in dovetailed grooves formed in the bed-block and has lips a formed upon its ends, which embrace the bit, and the movements of this slide are controlled by the spiral cam b, which projects into the groove formed in the slide, said cam being pivoted to the bed-block by the screw d. A thumb-lever e is formed with the cam for its manipulation, so that by drawing this lever to one side or the other the slide will be moved crosswise of the bed-block, and thereby swing the bit upon the washer O as the fulcrum, which, as is obvious, will adjust the cutting edge of the bit, and thereby permit the truing up of the same.

From this description it will be seen that effective means are provided for the adjusting of the bit vertically and also for the truing up of the same, as well as providing for firmly clamping the bit in any adjustment, the latter being especially true since the entire under surface of the clamp-plate fits against the bit, while the under surface of the bit fits against the bed-block, so that when the clamp-plate is drawn downward it will firmly hold said bit.

Having thus fully described my invention, what I claim as new and useful is —

1. In combination with a plane of the character described, a bed-block adjustably secured within the stock, an adjusting-lever fitted within a recess formed in the bed-block, an extension formed with the adjusting-lever and fitted within the recess in the stock, said lever having a hole therethrough, a bit having a central slot therein, a clamp-plate adapted to fit upon the upper surface of the bit, a clamping-screw threaded into the plate, a washer surrounding the screw and adapted to bear against the under side of the bit and fit within a hole formed in the adjusting-lever, a bushing also surrounding the screw and bearing against the washer, a clamping-bar fulcrumed against the under side of the bed-block having its lower end slotted to engage the head of the screw, and means — such as a thumb-screw for drawing the upper end of the clamping-bar toward the bed-block whereby the lower end thereof will be caused to draw the screw and the parts carried thereby downward, as and for the purpose set forth.

2. In combination with a plane of the character described, a bed-block adjustably secured within the stock, an adjusting-lever, an extension formed with the adjusting-lever, a bit adjusted thereby, a clamp-plate, a clamping-screw, a washer and bushing surrounding said screw, a clamping-bar and means for operating the same.

In testimony whereof I have hereunto affixed my signature in the presence of two subscribing witnesses.

To all whom it may concern:

Be it known that I, PHILO F. DRESSER, a citizen of the United States, residing at Glenwood , in the county of Mills and State of Iowa, have invented certain new and useful Improvements in Hand-Planes; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in hand-planes and more particularly to that class in which the bit or plane-iron is both longitudinally and laterally adjustable; and the object is to provide a simple, inexpensive, and effective means for accomplishing this purpose; and a further object is to rigidly secure the bit in the position to which it has been adjusted, so as to prevent accidental displacement while in use.

To these ends the invention consists in the construction, combination, and arrangernent of the device, as will be hereinafter more fully described, and particularly pointed out in the claim.

In the accompanying drawings the same reference characters indicate the same parts of the invention.

Figure 1 is a perspective view of a plane embodying my invention, the stock and bit being shown in dotted lines, while the bed-piece and the mechanism for adjusting the bit are shown in full lines. Fig. 2 is a longitudinal section through the bit and bed-piece. Fig. 3 is a bottom plan view of the bed-piece. Fig. 4 is a perspective detail view of the lever-operating mechanisrn for laterally adjusting the bit.

1 denotes the stock; 2, the wedge-clamp ; 3, the plane-iron or bit, and 4 the bed-piece, which may form a part of or be rigidly fixed to the stock.

5 designates a lever fulcrumed in the bed-piece, its inner arm 6 extending into a recess 7 in the plane-iron, while its outer arm 8 is bifurcated to encompass the cylindrical shank 9 of the milled-head nut 10, adjustably mounted on the threaded stud 12, rigidly fixed in the bed-piece. It will be seen that by adjusting the milled-head nut 10 on the fixed stud 12 a longitudinal adjustment of the plane-iron is effected.

13 designates a lever fulcrumed on a stud 14, fixed in the lower face of the bed, and its shorter arm is formed with a lateral boss 15, carrying a pin 16, on the projecting end of which is journaled an antifriction-roller 17, which extends into the usual longitudinal slot 18 in the plane-iron. The opposite or longer end of the lever 13 is formed with two parallel lugs 19 19, extending in an opposite direction to the boss 15 to encompass the sides of the periphery of the milled nut 20, mounted on the transverse screw 21, rigidly fixed in the parallel brackets 22 22, formed integral with the bed-piece. It will thus be seen that a rotary movement of the nut 20 causes it to travel longitudinally on the fixed screw 21 and carry the free end of the lever 13 with it. This movement causes the inner end of the said lever to move in a correspondingly-opposite direction and carry the plane-iron with it, thereby providing for the lateral adjustment of the plane-iron.

I am aware that the plane-iron has heretofore been adjusted by rneans of a lever, but the free end of the lever projected beyond the upper end of the bed-piece for convenience of manipulation and in this exposed position was liable to accidental displacement, there being no means provided for locking the free end of the lever. In the present construction it will be observed that the nut 20 when not rotating acts as a lock for the outer end of the lever 13, and thereby prevents its movement in either direction.

The accompanying drawings show my invention in the best form now known to me, but many changes in the details might be made within the skill of a good mechanic without departing from the spirit of my invention as set forth in the claim at the end of this specification.

Having thus fully described my invention, what I claim as new and useful, and desire to secure by Letters Patent of the United States, is —

In a hand or bench plane having a laterally-adjustable plane-iron, the bed-piece 4 fined to the stock and the transverse screw 21 rigidly fixed thereto, the milled nut irremovably traversing said screw, the lever 13 fulcrumed on said bed-piece, with its upper end encompassing the contiguous edge of the milled nut, and the friction-roller 17 journaled on the lower end of said lever to engage the slotted plane-iron, substantially as and for the purpose set forth.

In testimony whereof I have hereunto set my hand in presence of two subscribing wltnesses.

To all whom it may concern:

Be it known that I, HENRY MILLER, a citizen of the United States, residing at Mexico, in the county of Juniata and State of Pennsylvania, have invented a new and useful Bench-Plane, of which the following is a specification.

This invention relates to bench-planes; and it has for its object to equip a plane of this character with improved bit-adjusting mechanism which shall provide simple and efficient means for positively and quickly adjusting the bit or knife of the plane to a proper working position.

To this end the main and primary object of the invention is to provide an improved bit-adjusting device for planes having means for effecting a compound adjustment of the bit — to wit, a longitudinal adjustment to secure the proper “set” of the cutting edge in the bit-opening and a lateral adjustment to accurately center the bit.

A further object of the invention is to provide improved means in connection with the bit-adjusting device for securely holding the clamping-plate of the bit, so as to prevent longitudinal displacement thereof after the parts have been set and tightened up.

With these and other objects in view, which will readily appear as the nature of the invention is better understood, the same consists in the novel construction, combination, and arrangement of parts hereinafter more fully described, illustrated, and claimed.

While the improvements contemplated by the present invention are necessarily susceptible to modidcation without departing from the principle or scope of the invention, still the preferred embodiment thereof is shown in the accompanying drawings, in which —

Figure 1 is a plan view of a bench-plane fitted with the improvements contemplated by the invention. Fig. 2 is a vertical longitudinal sectional view of the plane. Fig. 3 is a transverse sectional view on the line 3 3 of Fig. 2. Fig. 4 is a plan view of the plane-stock equipped with the improvements and showing the plane bit or knife and the clamping-plate therefor removed.

Referring to the accompanying drawings, the numeral 1 designates the plane-stock of an ordinary bench or smoothing plane, provided near its opposite ends with the usual handle and knob, (designated by the numerals 2 and 3, respectively,) and at an intermediate point the said plane-stock is provided with the mouth 4, communicating with the transverse bit-opening 5 at the under side of the stock and receiving therein the plane bit or knife 6. The plane bit or knife 6 is arranged in the usual inclined position within the mouth 4, with its cutting end disposed in the transverse bit-opening 5, and said plane bit or knife 6 has fitted to the upper side thereof the usual adjustable cap-plate or back iron 7, whose lower end is beveled and adjustable relatively to the cutting end of the bit or knife 6 in the usual manner, according to the character of the work required of the plane. Cooperating with the plane bit or knife 6 and the cap-plate 7 is the clamping-plate 8, which is arranged on top of the latter and carries at its upper end the clamping-screw 9, whose inner end works against a clamping-spring 10, secured fast at one end to the under side of the plate 8 and adapted to have its free end pressed by the screw 9 tightly against the cap-plate of the plane bit or knife to provide for clamping the same rigid after being set, this combination and arrangement of parts being common to most of the ordinary types of bench or smoothing planes.

To provide for adapting the adjusting device or mechanism to the parts of the plane just described, a guide-boxing 11 is securely fastened at its lower end by means of screws or other suitable fasteners within the plane-mouth 4, and said guide-boxing 11 is provided with a central longitudinal channel or way 12 and opposite side rest-flanges 13, which follow the inclination of the blade-seat next to the transverse bit-opening 5, so as to form an even rest or support for the plane bit or knife. The said guide-boxing 11, by reason of its inclination and the provision of the flanges 13, forms an extended inclined support or rest for the plane bit or knife 6, and the longitudinal channel or guideway of said boxing accommodates for movement therein a slide-block 14, to which is swiveled one end of an adjusting-screw 15, working through a fixed nut 16, secured fast to the boxing, near the upper end thereof, and the upper outer end of said adjusting-screw 15 carries an adjusting disk or wheel 17, which by being turned provides for the sliding movement of the block 14 in the direction desired.

The slide-block 14 has pivotally mounted thereon a laterally-swinging adjusting-lever 18, which lever is provided below its pivotal connection with the block with an upstanding stud 19, having a loose or pivotal engagement in the stud-opening 20, formed in the plane bit or knife G or the cap-plate thereof. At its upper outer end, which projects beyond the upper end of the boxing 11, the said lever 18 is provided with a laterally-deflected thumb-piece 21, which is grasped to provide for swinging or adjusting the lever on its pivot.

From the foregoing it will be readily understood that in order to secure the longitudinal adjustment of the plane bit or knife to provide for the proper set of its cutting edge in the bit-opening it is simply necessary to turn the disk or wheel 17, which will cause a longitudinal movement of the slide-block, as well as the adjusting-lever 18, carried thereby, and which connects with the plane bit or knife. To correct any angularity of the bit or knife and thereby properly center the same, a lateral movement of the adjusting-lever on its pivot will effect this result, and at this point it will be observed that the adjusting-lever and the plane bit or knife are arranged in substantial parallelism, thereby permitting the adjusting-screw a free play through the entire length of its threaded portion, while at the same time providing for exerting a direct longitudinal pressure on the bit in adjusting the same backward or forward, which would not be the case if the adjusting-screw were arranged at an angle to the plane of the bit.

In addition to the adjusting device described the present invention also contemplates the use of a pair of holding-arms 22. These holding-arms 22 are fitted to the guide-boxing, within the plane-mouth, at opposite sides thereof and at right angles to the inclination of the plane bit or knife, and at their upper ends the said holding-arms are provided with inwardly-projecting gripping-lugs 23, which overhang the side edges of the clamping-plate 8, and are provided with pointed edges 24, engaging superlicial serrations 25 at opposite edges of the clamping-plate 8. This construction prevents longitudinal displacement of the clamping-plate 8 after the parts have been properly set and tightened up by means of the screw 9.

From the foregoing it is thought that the construction, operation, and many advantages of the herein-described plane attachment will be readily apparent to those skilled in the art without further description, and it will be understood that changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

Having thus described the invention, what is claimed as new, and desired to be secured by Letters Patent, is —

1. In a plane, the combination with the stock and the bit or knife, of a channeled guide-boxing fitted to the stock, a longitudinally-adjustable slide-block completely housed and concealed within the channel of the boxing, and a laterally-swinging adjusting-lever pivoted between its ends to the block and provided at its lower end with an upturned stud loosely engaging with the bit or knife, substantially as set forth.

2. In a plane, the combination with the stock, and the bit or knife, of a channeled guide-boxing fitted to the stock, a fixed nut housed within the boxing at or near its upper end, a slide-block registering and concealed within the channel of the boxing, an adjusting-screw mounted in said nut and having a connection with the slide-block, and a laterally-swinging adjusting-lever pivoted between its ends to the block and provided with an upturned stud loosely engaging with the bit or knife, substantially as set forth.

3. In a plane, the combination with the stock, the bit or knife, and the clamping-plate, of a guide-boxing fitted to the stock, adjusting devices for the bit or knife arranged within the guide-boxing, and a pair of holding-arms fitted to the guide-boxing at opposite sides thereof, within the plane-mouth, and provided at their upper ends with inwardly-projecting gripping-lugs overhanging and engaging the side edges of the clamping-plate, substantially as set forth.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.
