sPEoIrIoAr-Io'iv forming part of Letters Patent No. 382,064, dated May 1, 1888.

Application filed December 15, 1886. Serial No. 221,626. (No model.)

To aZZ whom, it may concern:

Be it known that I, CHAUNsEY L. S. WALKER, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Machines for Forming Saw-Handles; and I do 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 appertains to make and use the same, reference being had to the accompanying drawings, and

more quickly than heretofore, thereby reducing the cost of manufacture.

The invention consists in an improved machine for forming saw-handles and in thearrangements and combinations of parts thereof, substantially as will be hereinafter set forth, and finally embodied in the clauses of the claim. 7

Referring to the accompanying drawings, in which like letters indicate corresponding parts in each of the several figures of the four sheets thereof, Figure 1, Sheet 1, is a side elevation of my improved machine, showing in dotted outline the different positions of a saw-handle and slide-rest in the operation of forming a portion of said saw-handle. Fig. 2 is an enlarged detail of an arbor, shaft, or mandrel provided with a cone-pulley and adapted to hold the cutters. Fig. 3 is an end view of my improved machine, showing the cutters mounted in position on said arbor, shaft, or mandrel. Fig. 4., Sheet 2, is a plan of the same; and Fig. 5 is a section through line X, Fig. 4.. the sliderest being removed. Fig. 6, Sheet 3, is'an enlarged detail of a certain cam-rod for raising orlowering the center of pivotal motion of said slide-rest. Fig. 7 is an enlarged detail sectional view through line Y, Fig. 4, Sheet-21 Fig. 8 is a plan view of a blank or cutter carrier to which are attached the cutters for forming certain parts of said handle. Fig. 9 is a side elevation of the'same; and Fig. 10 is a section through line Z, Fig. 8. Fig. 11 is a plan of certain guides attached to a pi'votallyarranged rest or plate; and Fig. 12 is a section through line V, Fig. 11. Fig. 13 is a plan view of one of the pivotal centers of the slide-rest; and Fig. 14 is an end view, partly in section, showing the said centers in connection with saidcam'rod, whereby-said centers can be adjusted to any desired height. Figs. 15, 16, 17, 18, and 19, Sheet 4., are side elevations of certain cutters for forming the beads on said sawhandle. Fig. 20 is a section through line W, Fig. 19; and Fig. 21 is a side elevation of a cutter or knife to be used in connection with the form of cutter-carrier shown in Figs. 8, 9, and 10, Sheet 3. Fig. 22, Sheet 1, is a side elevation of a modification of the pivotal center shown in Figs. 13 and 14., Sheet 3.

Insaid drawings, A represents the bed of my improved machine, which may be of any convenient form and may be provided with arms or supports B B near one end to receive an arbor, shaft, or mandrel, as O. Said arms or supports may be and preferably are slotted near the top thereof to receive adjustable bearings D for said shaft 0. Said bearings, as here illustrated, are slotted, as at E, Fig. 5, and secured to said arms or supports B by a screw passed through said slot in the ordinary manner, thus allowing said arbor, mandrel, or shaft 0 to be moved horizontally a limited distance in either direction. Said arbor, shaft, or mandrel is adapted to receive a pulley, as F, and cutters, as G G and H H, and may be provided with a screw-thread and nut at one end thereof, as indicated in Figs. 2 and 5, or a wedge-shaped collar and pin, as in Fig. 3. Thus by tightening said nut or wedge-shaped collar the cutters are held firmly to the shaft, so as to be turned thereby when said shaft is driven by said pulley. Said bed A provides a bearing for a sliderest, I, and a guide, J, the latter working in a suitable groove in said bed A, and said rest I is also provided witha bushing or strip, K, Fig. 3, to support the opposite side of said rest. Thus said rest is guided in a straight backward and forward motion at or approximately at right angles to the central line of the shaft, arbor, or mandrel carrying the cutters. Said slide-rest I is provided with supports L at the sides thereof, which serve to carry the bearings M of a pivotallyarranged plateor carrier for thesaw-handle. Said plate or carrier N is designed to act as a rest for the saw-handle, which is held in close relation to said plate N by means of a clamping device consisting of a lever, as O, fulcrum, as P, and cam or eccentric, as Q, the latter being operated by a handle, as S. By this construction when the handle S is raised the sawhandle may be inserted. Then by pressing .the handle downward the said saw-handle is held in a fixed relation to said pivotally-arranged plate or carrier N. .Said plate N is provided with a handle, as R, in order that it may be more easily turned on its pivot and made to operate, as will be hereinafter referred to. Said supportsLalso provide pivotal bearings for a guide plate, as T, provided with guides U, as indicated in Figs. 1, 4, 11, and 12. Said guides (in this case three in number) may be secured to said plate T by means of set screws passing through a slot in said guide, thus allowing them to be adjusted to serve as guides for saw-handles of different sizes. One of the pivotal centers of the guideplate T extends beyond its bearing in said support L, as shown at it, (see Fig. 1,) and is provided with an arm, A, having an adjustable wedge-shaped extension, A. Said arm A is rigidly attached to one of said pivoted centers and is provided with a set screw, whereby said wedge-shaped extension A may be adjusted, and is adapted to engage a pin or other projection on a standard, as B, attached to the bed A, Figs. 1, 4, and 7. Said supports L are suitably slotted to receive a cam-rod, O, as indicated in Fig. 14. The pivotal center of the plate N is fixed to vertically-movable dovetailed pieces D, which rest on said cam-rod, and may be raised or lowered by moving said cam-rod horizontally or longitudinally, as is evident by reference to Figs. 6 and 14; or the distance between the plate N and its pivotal center may be changed by securing the bearing M to the support L and having the movable sliding piece D and cam-rod 0 attached to the plate N, as shown in Fig. 22, Sheet 1. Thus any height of pivotal motion may be secured within certain limits of the plate N by adjusting said cam-rod G with a set-screw or other means, as will be understood.

The cutters G, as shown in detail in Fig. 21, Sheet 4, may be and preferably are twelve in number, arranged in sets of four and secured by means of screws or otherwise to a cutter carrier or form, as F. (Shown in detail in Figs. 8, 9, and 10, also shown with the knives attached in Figs. 1, 3, and 4.) Said cuttercarricr has the inclination or each quarter of it is tapered, as indicated in Figs. 9 and 10, in order to give the knives the best cutting position in relation to the saw-handle when attached thereto. Said cutter carrier or form is also provided with a perforation to allow it to be mounted upon a shaft, arbor, or mandrel, as shown in Figs. 1, 3, 4, and 5.

The cutters H are five in number and are circular and provided with teeth or cuttingedges similar to theteeth of asaw, except that they are all on one side of said cutter instead of alternating,asin a saw. Said euttersHare adapted to fit on said arbor, shaft, or mandrel O by being suitably perforated. Allsaid cutters are arranged on said arbor, shaft, or mandrel in the order shown in Figs. 3, 4, and 5, and are adapted to out the beads and form portions of the saw-handle contiguous thereto, as indicated in Fig. 4, it being preferable to have the periphery ofsaid beads curved; hence the pivotal motion of the plate or carrier N on said slide-rest I is used to give the proper contour to said beads, asisindicated in Fig. 1.

When the slide-rest is drawn back, the arm A is automatically raised by coming in contact with a lug or pin on the post B, (said lug or pin is at or near thetop of said post B,and is indicated by a dotted line and lettered F in Figs. 4,) thus raising the guide-plate T to the position shown in Fig. 1, and by raising the handle S, which operates the lever O, a sawhandle blank may be inserted under said lever 0 and in the proper position by allowing it to come in contact with the guides U, which are so placed as to insure such result. Then said handle S may be lowered, thus clamping said saw-handle, and the slide-rest pressed forward, with the handle R lowered, so as to bring the saw-handle into the position shown in dotted outline in Fig. 1. The guide-plate drops out of the way automatically after the arm A passes the post B, and the cutters be ing revolved by means of a belt and pulley, as F, the slide-rest is pressed forward until the stop E engages the edge of the plate A. Then the handle R is raised, which brings the sawhandle into the second position shown in dotted outline in Fig. 1, thus completing the cut, as will be readily manifest. When the rest I is drawn back, the guide-plate T and guides U are brought again into position, as shown in Fig. 1. The finished handle may then be removed and a handle-blank be inserted and put through the same operation.

Suitable adjustable stops, as E,'Fig. 1, are, as here indicated, arranged at the ends of the slide-rest, in order that the feed movement may be adjusted so that the cutters will make the depth of cut desired; or other suitable means may be employed to limit the depth of cut or forward motion of the slide-rest, as will be understood.

The cutters may be separated any desired distance on the shaft, arbor, or mandrel C by means of washers, as D, or a number of washers, as shown in dotted outline in Fig.2, thus separatingthe cutters, so that the beads may be cut at the proper place in saw-handles of different sizes.

I do not wish to be understood as limiting myself to the exact form and proportion of parts as herein shown, as it is evident that oted holding device for holding and. guidingsaid saw-handle to said cutters, substantially as and for the purposes set forth.
