IMPROVEMENT IN MACHINES FOR MAKING METALLIC SHOE-SHANKS.

.Specification forming part of Letters Patent No. 129,347, dated July 16, 1872 Reissue No. 5,197, dated December 24, 1872; Reissue No. 8,163, dated April 9, 1878; application filed August 10, 1877.

To all whom it may concern:

' Be it known that I, JOHN HYsLoP,Jr., of

Abington, in the county of Plymouth and Qommonwealth of I Massachusetts, have invented an Improvement in Machines for Making Metallic Shoe-Shanks, of which the follow- The 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 reversely bent, the operations being continuous or automatically successive; and the invention consists in the combination and arrangement of mechanism for cutting, punching, and bending shoe-shanks.

The drawings represent a machine embodying my invention.

Figure 1 shows the machine in front elevation. Fig. 2 is a rear elevation thereof. Fig. 3 is a vertical section on the line .70 m. Fig. 4 is a horizontal section on the line y y. Figs.

5 and 6 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 stationary cutter, in connection with which a vertically-reciprocating cutter, 0, acts to shear the Sheet or sever from its front end the shank-forming strip. The cutter is fixed to a head, d, sliding vertically in suitable guideways e, and'actuated from an eccentric on a driving-shaft, f, by connection therewith by a link, 9. In rear of the bed b are lips or flanges h, against which the front edge of the plate is held to gage the forming end is presented to the action of punches, for punching holes in its opposite ends, the punches 0 extending down from punch-blocks 10, and entering holes q in a bedpiece, 1', 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 point where the punches are to operate. When the cutter descends to cut a strip from the end of the plate, the punches descend and punch the holes in thegpart of the metal from which the next blank will be cut, the punch-blocks being fixed to the same head that carries the cutter. One edge of the guide-table n is made with a lip, u, to guide, or gage the plate, and the distance from the end at which one of the punchholes is made, thepunch-block 10 being fixed;

but the other punch-block, by means of suitable screws and slots, is made adjustab'i thus making provision for relative adjustment between the punches in accordance with the varying sizes or lengths of shanks to be formed at dilferent times. Under the incline m, down which the punched and severed blank slides, is a concave face, '0, in front of which is a reciprocatin g con vex-faced bender-plate, w, slidin g in guideways m, and having movement imparted toit by a lever, one arm, 3 of which is in contact with a cam, 2, on the shaft f, while the other arm, a acts against the bender plate to drive it forward, the plate being drawn back by a spring, b". As the shaft turns, the cutters first sever a blank from the end of a plate, and the severed blank slides down the incline, and is arrested by stoprpins c and the continued rotation of the shaft then carries the ben der-plate 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 01 the previouslybent 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 concavity, thereby imparting to it its long longitudinal bend. Extending from the bender-plate are two pins, 0 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,eand their lower ends are placed at a distance apart equal to the length of the shanks, these lips being adjustable as to distance apartfor various lengths of shanks. When the bender is drawn back, the stop-plate d is swung back, and thefinished shank drops from the machine.

The shank thus made may be of uniform breadth, as seen at Fig. 5, 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 oft from the strip one by one, but each is punched, as seen at Fig. 5, and formed with the long bend f and the two reverse bends g at the opposite ends; and by the ma- 7 chine 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 Patent' 1. In a machine for making metallic shoeshanks, the combination, substantially as described, of the punching mechanism, the cutting mechanism, and the bending mechanism, arranged to operate as set forth.

2. In a machine for making metallic shoeshanks, the plate (P, the convex-faced benderplate w, and the concave face 1), in combination, for the purpose above specified.

3. In a machine for making metallic shoeshanks, the combination, with the fixed or stationary bending-die and movable bendingdie, of a pair of stop-pins, 0 secured to thetop, and plate d at the bottom, of the movable die, for arresting and holding the blanks, as described.

4. In a machine for making metallic shoeshanks, the combination, with the fixed or stationary bending-die and movable bendingdie, of a pair of pins or projections, 0 extending from the bender-plate, whereby the middle and reverse bends of a metallic shoe-shank are formed at one and the same operation, as described.

5. In a machine for making metallic shoeshanks, the combination of the cutting and punching mechanism, chute m h, stop-pins 0 dies 4: w, and projections 6 all arranged and operating in relation to each other substantially as described, whereby the shoe-shank is cut and punched, conducted to the dies, pressed into shape, and discharged automatically.

6. In a machine for making metallic shoeshanks, in combination with the concave-faced stationary die 1:, the reciprocating convexfaced bender plate or die w, with stop-pins c projections 0 and plate (1 secured thereto, as described, for the purposes specified.
