SPECIFICATION forming part of Letters Patent No. 443,679, dated December 30, 1890.

Application filed September 13,1890. Serial No. 364,848- (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM J AMES, of Adelaide, South Australia, have invented a new and useful Improvement in Machines for IVorking Leather, &c., of which the following is a specification.

My invention relates to an improvement in combination-machines for working leather and other materials in which a vertically-adjustable yoke is adapted to receive interchangeable tools, which, in connection with a suitable support, serve to operate upon the leather in the desired manner.

My invention also provides for working upon the edges of broad sheets of material chine, showing in connection therewith a roiary spindle carrying pricking-wheels for indicating both straight and sinuous lines of stitching. Fig. 2 is a transverse vertical section from front to rear. Fig. 3 is a View in detail of the guide, and showing its connection with the frame. Fig. 4 is a view in side elevation in detail of acam-support for purposes of skiving and splitting. Fig. 5 is an end view of the same. Fig. 6 is a View in detail of a roller for supporting different widths of straps or strips of material, the edges of which are intended to be operated upon. Fig. 7 is a side View in detail of the oval pricking-wheel.

The main frame of the machine consists of a base portion A, from one end of which a short upright portion a extends, and from the opposite end of which an upright portion a extends upwardly, thence laterally, as shown at 00*, and thence downwardly, as shown at a to a point a short distance above the short upright portion a. The inner faces of the V upright portions a and a are provided with longitudinally extending grooves B, which terminate at their lower ends, one at the opening between the parts a and a of the frame and the other in a recess 12, which extends inwardly from the front of the upright portion a. The opening between the parts a and a and the recess 1) are intended to be of such width as to receive therein the squared ends of bearings C of theinterchangeable spindles which support the various tools. The grooves B in the inner faces of the portions a and a of the frame are also intended to correspond to the said squared portions 0 of the bearings, and to receive them with an easy sliding fit when they havebeen inserted within the opening upon one side and the recess b upon the other side in position beneath the' lower end of the grooves.

Between the inner faces of the portions a and a there is located a yoke D, the ends of which are turned downwardly and rest with their outer faces in close sliding contact with said inner faces of the frame. The downwardly-turned ends of said yoke are provided with recesses d, which open toward the front edges of the ends, and which are adapted to receive the squared ends 0 of the tool-holding spindles when the latter are slid rearwardly into position to be received within the grooves 13. The yoke D is connected at its middle portion with an adjusting-screw E, provided with a hand-wheel c, said adj Listing-screw being seated in a threaded socket formed in the top portion a of the frame and having its lower end connected with the yoke so as to turn freely, but at the same time locked to the yoke so as to cause the yoke to rise and fall as the screw is turned up or down within its threaded socket of the frame. In the present instance I have shown the lower end of the screw provided with a disk portion e, from the lower face of which projects a reduced cylindrical portion 6 The reduced portion e extends through and works freelyin a socket formed in the yoke, and is provided at its lower end beneath the yoke with a disk a which is fixed to the reduced portion' 0 so as to prevent it from being with.- drawn from the socket in the yoke, thereby causing the yoke to follow the up anddown movements of the screw.

As supports for the work to be operated upon, I provide interchangeable rollers, three examples of which are represented in the accompanying drawings. In Fig. 1 I have shown a cylindrical roller F, loosely mounted upon a removable spindle G, seated in suitable bearings formed in the upright portions 1/. and a of themain frame and conveniently provided with. a handle 9 for withdrawing it from the l'rameand from the roller I through which it extends, and thereby allowing the ready removal of the roller forthe purpose of inserting one of another form.

For the purpose of guiding the nmterial to be operated upon truly beneath the operatingtools, I have provided the back of the frame with a supporting arm ll, extending laterally across the opening between the uprights u. and o. of the frame and provided at one end with a vertically-elongated slot 7i for the purpose of adjusting the arm up and down to bring its upper surface into the proper relation to the surface of the roller or work-support in use. The said arm II is adjusted and supported by means of a headed stud 7t, which projects rearwardly from the main frame, and is adapted to be received through the wider portion of the slot 71 and when so inserted and the arm slid upwardly for a slight distance the sides of the head of the stud it will engage the said arm at the opposite edges of the slot and preventit from outward displacement. In addition to the stud It, a bindingscrew 7L2 is inserted through the slot into the frame and serves, together with the stud 71 to lock the arm in the desired. adjustment. Upon the arm II a pair of guidecheeks I are located and adapted to slide. The said checks are locked in any desired position upon the arm by m ans of binding screws 2'.

W'hen it is desired to work upon the edge of a broad sheet of leather or other material, the space between the portions a and a of the main frame is left open, and through this the material may be passed while its edge is engaged by the tools. When, however, it is desired to do fine work simultaneously upon the opposite edges of narrow strips or thro ughout a great extent of the width of the strip, it is desirable that the portion of the frame supporting the cutting-tool should not be allowed to spring back from its work at either edge. To prevent this I provide a brace K, pivotally secured atits lower end to the outer edge portion a of the main frame, preferably by means of a screw 70, and at its upper end provided with a binding screw 71:, which, when the brace is swung into position, is adapted to engage a threaded perforation in the outer edge of the portion a of the main frame, and thereby secure the brace in position, connecting the portions to and a" of the frame, wholly preventing any tendency of the frame to yield at that end of the spindle or at that edge of the material being operated upon.

In Fig. 1 I have shown a rotary spindle L, squared for the purpose of preventing the rotary movement of the tools supported thereon, and provided with a scrcw thread at its corners for the purpose of operating adj usting-nuts Z thereon to hold the tools in position. The said spindle is here shown as provided with a pair of prickingavheels Z, adjusted the desired distance apart for indicating the position of parallel seams, and also a pricking-wheel 1 of oblong shape, secured in an oblique position upon the spindle by means of a pair of oblique-faced cheeks If. The spindle is also shown as provided with a crank M, having a handle m for rotating it.

In Fig. 4: I have represented a cam-roller l1", which maybe utilized both for skiving and for splitting leather or other strips of material.

In Fig. (i I have shown a roller provided with annular recesses of various widths for the purpose of thinning the edges of. leather or other material.

The spindles carrying the work-tools are adj ustedin the frame by lowering the yoke to a position such that the recesses in its ends will correspond with the recess 1) in the frame and the opening between the parts a a, and then inserting the squared ends of the spin die or spindle-bearing rearwardlyinto the recesses in the yoke, and then, by means of the screw E, elevating the yoke, thereby drawing the said squared ends 0 of the spindle upwardly into the grooves Ilof the main frame. In this position the spindle is securely locked against both lateral and vertical displacement, and may be adjusted vertically at pleasure by means of the screw E.

For the purpose of giving the roller or work-support a yielding adjustment when the class of work performed--as, for example, trimming-den1ands it, I provide a springcushion, upon which the roller-spindle may be supported. I11 the present instance this is represented as a stem 0, provided with anut 0 for adjusting it vertically, the said stem having two spring-arms o branching there from, the ends of the arms restingin position to engage the under side of a bar 0*, having standards to engage the ends of the rollerspindle when it rests in its bearings. The roller spindle-bearings are for this purpose elongated vertically.

'hat I claim as my invention is-- 1. The combination, with a frame consistin gof upright portions provided with grooves in the opposite inner faces and with openings from the side of the frame to said grooves, a

tool-holdlug-spindle, and a tool, of a yoke provided with recesses for the reception of the tool-holdin g spindle, said recesses in the yoke corresponding with the grooves in the frame,

means for adjusting the yoke longitudinally of the grooves in the frame, and a removable support for interchangeable rollers or worksupports seated in the frame, substantially as set forth.

2. The combination, with a frame consisting of a portion extending upward, laterally, and downward and permanently connected with the base at one end only, the said frame being provided with grooves in the opposite faces of its upwardly and downwardly ext-encb ing' portions for the reception of a tool-holding spindle, of the tool-holding spindle and tool, and an adjustable brace for connecting the free end of said frame rigidly with the base or releasing it therefrom, the opening across which the said brace is arranged to extend being located in position to receive the material to be operated upon While traveling in engagement with the tool, substantially as set forth.

3. The combination, with the frame provided with a seat for the tool-holding spindle, the tool-holding spindle, and interchangeable tools adapted to the spindle, of a removable support for interchangeable rollers or Worksupports, a guide-supporting arm secured to the main frame in vertical adjustment to correspond with the varying positions of the surface of the work-supports, and laterally-adjustable checks secured on the arm to guide the work to suit the interchangeable tools, substantially as set forth.

4. The combination, with the frame and the vertically-adj ustable yoke, of the spindle seated in the frame and yoke, an oval-shaped pricking-Wheel secured in an-oblique position upon the spindle, and the Work-support, substantially as set forth.

5. The combination, with the frame and the spindle-support, of a squared spindle for re ceiving the tools, and said tools, the corners of the spindle being screw-threaded, and adjusting-nuts working in the spindle to adjust the tools, substantially as set forth.
