IMPROVEMENT IN MACHINES FOR MAKING METALLIC SHOE-SHANKS.

Beit known that I, JOHN HrsLoP, Jr., of

Metal Shoe-Shanks, of which the following is a specification:

rlhe invention relates to the organization of a machine by which, from sheet-steel or other metal of requisite width, metal shanks for boots and shoes are cut, punched, and bent, and have their opposite ends reverse bent, the operations being continuous or automatically successive 5 and the invention consists in the combination and arrangement of mechanism for cutting, punching, and bending shoe-Shanks.

The drawing represents a machine embodyin g my invention.

Ashows the machine in front elevation. B is a rear elevation thereof. C is avertical section on the line m. l) is a horizontal section on the line y y. E and F are views of one of the shanks.

a denotes a strong` upright frame, in which is supported a bed or bed-cutter, b, the rear edge of said bed being the stationaryr cutter, in connection with which a vertically-reciproeating cutter, c, acts to shear the sheet or severfrom its front end the shank-forming strip.

tically in suitable guideways e, and actuated from a'n eccentric on a driving-shaft, f, by connection therewith by a link, g. In rear of the bed b are lips or flanges h, against which the front edge ofthe plate is held to gage the cut, and when the blank is cut it falls down an ineline, m, and is guided bythe lips h so that it sented to the action of the shaping mechanism. The plate to be cut is fed to the action of the cutter over a guide-table, n, by the agenand, before being cut, each shank-forming end is presented to the action of punches for punching holes in its opposite ends, the punches 0 extending down from punch-blocks p, and entering holes q in a bed-piece, r, over which the plate passes. The plate is pressed up by a follower, s, and before ,passing under the punches the edges pass under sponges t, which are saturated with oil, and lubricate the plate at the points where the punches are to oper ate. When the cutter descends to cut a strip from the cndof the plate, the punches descend and punch the holes in the part of the metal from which the next blank will be cut, the punch-blocks being iiXed to the same head that carries the cutter. One edge of the guidetable a is made with a lip, u, to guide or gage the plate, and the distance from the end at which one of the punch holes is made, the punch block p being fixed; but the other punch-block, by means of suitable screws and slots, is made adjustable, thus making provision for relative adjustment between thepunch es in accordance with the varying sizes or lengths of shanks to be formed at different times. Under the incline m, down which the punched and severed blank slides, is a concave face, c, in front of which is a reciprocating convexfaced bender-plate, w, sliding in guide- Ways x, and having movement imparted to i1; by a lever, one arm, y, of which is in contact With a cam, z, on-the shaft f, while the other arm a2 acts against the bender-plate to drive it forward, the plate being drawn back by a spring, b2. As the shaft turns the cutters rst sever a blank from the end of a plate, and the severed blank slides down the incline and is arrested by stop-pins c2, and the continued rotation of the shaft then carries the benderplate forward, causing it to bend the previous shank into the concavity. When the bender is drawn back the pins permit the shank-blank to fall by them, and the blank lodges upon plate d2, the previously-bent shank having fallen by said plates, and the blank is then ready for the action of the bender-plate, which advances and presses the shank into the con cavity, thereby imparting to it its long longi* tudinal bend. Extending from the bender plate are Vtwo pins, c2, which, when the bender advances, strike the ends of the blank and form the reverse bends at the end thereof. To center the shank previous to the action of the bender-plate and pins, so that the pins shall operate at the right points, the guides h incline inward, and their lower ends are placed at a distance apart equal to the length of the Shanks, these lips being adjustable as to distance apart for various lengths of shanks. When the bender is drawn back the stopplates d2 are swung back, and the finished shank drops from the machine.

The shank thus made may be of uniform breadth, as seen at E, or may be made Wider at one end than at the other; and by' the action of the machine the shanks are not only cut 0E from the strip one by one, but each is punched, as seen at E, and formed with the long bend f2 and the two reverse bends g2 at the opposite ends and by the machine, organized as shown, the shanks may be rapidly, perfectly, and inexpensively produced.

Having thus described my invention, I claim as new and desire to secure by Letters Patentl. The combination of the punching mech- 'anism, the cutting mechanism, and the bend- 2. The arrangement of a lfixed or stationary bending-die and a movable bendingdie of suitable form for bending a plate to form the middle curve of a shoeshank, and actuating devices therefor, in a machine adapted for cutting and punching said blanks, in such manner that the blanks are received in the bend- Witnesses: y
