IMPROVEMENT 1N MACHINES FOR MAKlNcHoRsEsl-IOES.

Specification forming part of Letters Patent No. 84,04 3, dated November l0, 1868.

To all whom it may concern:

Be it known that I, J AGOB ZEPF, of Troy, in the county of Rensselaer and State of New York, have invented a new and usefulMachine for Forming and Pressing Horseshoes; and I do hereby declare that the following is a full, clear, and exact description of the construe tion and operation of the same, reference being had to the annexed drawings, makin ga part of this specication, in which-,-

Figure lis a side elevation. Fig. 2 is a section on plan A B; Fig. 3, plan; Fig. 4, plan of a device for delivering the shoe-blank to the dies.

Upon a bed or table, C, are two raised standards, D D, near the top of which is a shaft, E, upon which and between the standards D D are secured. the cams F and G. Below the shaft E, and between the standards D D, is a cross-piece, H, through which, in suitable bearings, play the vertical plungers I and J, which are operated respectively by the cams F and G. To the plunger I is attached a cutter, h, for cutting the blank from the bar. To the plungerJ is attached the male die i, of the size and shape of the shoe desired to be made. Both the plungers have suitable springs attached, for the purpose of bringing them back into position after being acted upon by the cams F and G. Swinging upon the cross-piece His an arm, l, to the lower end of which is attached a roller, for bearing upon the bar of iron as it is fed to the machine, for the purpose of keeping it down on the bed. At the rear of the bed O is a shaft, K, to which are secured the cams L and M M. Moved and worked by the cams M M are two eccentrics, N N, which impart a reciprocating motion to the inclined planes O O, and to which they are connected by the connections P P, which connections can be lengthened or shortened by the screw-couplings Q Q in the bed of the machine. Between the standards D D, and moving on suitable ways or guides, are two dieheads, S S. Attached to the outside of the dieheads are suitably-inclined planes T T, which are acted upon by the inclined planes O O. At the inside of the die-heads are attached the halves U U of a female die, of a size and shape to correspond to the male die t'. Extending from and operated by the cam L is a reciprocating rod, It, to the forward end of which is attached the fork or tender V, for delivering the blank to the dies. At one end of the shaft E is a gear, W. At the other end is a bevelgear, X. At one end of the shaft K is a gear, Y, and at the other a cam, Z. On one side of the machine is the feeding apparatus, consisting of a vertical shaft, a, the bevel-gear b, and the milled feeding-wheels c and d. The feeding-wheel d turns upon a shaftin a reciprocat ing arm, c, which is operated by the cam Z. At the sides of the machine are set-screws ff, which act upon the plates g g so as to bring the inclined planes O O nearer the center of the machine, thus bringing the die heads nearer together. Extending from the outside of the die-heads S S, and below the inclined planes T T, are two rods, j j, which extend through the sides of the machine, and which have suitable springs attached, which serve to keep the die-heads S S apart, except when they are being acted upon by the inclined planes O O.

The construction of the male die i is clearly shown in the section of the machine, Fig. 2, in which it will be seen that it has creasers 7a k attached, and that the part below the creasers is smaller, and extends downward between the die-heads S S, and conforms, just below the creasers, to the center of the shoe.

The manner of operating the machine is as follows: A bar of iron, after being brought to a proper heat, is placed between the feedingwheels c and d. The cam Z then moving the arm e forward causes the feeding-wheels to bear upon the iron a sufficient time to feed it forward a suitable distance. The cam F then operating upon the plunger I, with its cutter h, forcing it down, cuts the blank from the bar of iron; the cam l then moving the rod It and fork or bender Y forward, forcing the blank against and bending it around the male die t' under and below the creasers k k the cam G then operating upon and forcing down the plunger J and male die t', bringing the part of the die below the creasers 7c L', with the blank for the shoe between the halves U U of the female die; the cams M M then operating the eccentrics N N, and, by means of the connections P P, moving forward the inclined planes or cams O O, which, acting upon the inclined planes T T, move toward each other the dieheads S S, with the halves U U of the female die, causing them to press upon and form thev outside of the shoe. vThe male die at the same time pressingdown upon the shoe-blank, pressing it between the male die and the top of the female die, forms the top and bottom ofthe shoe, and at the same time creases it. The cams M M, by means of the eccentrics N N and connections P P, then drawing back the inclined planes() O, allow the die-heads to operate, and the finished shoe drops down through the aperture thus formed into aproper receptacle.

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

1. The arrangement of the sliding arm e and Witnesses:
