HORSESI-IOE-MACHINE.

Specification forming part of Letters Patent No. 27,750, dated April 3, 1860; Reissued April 21, 1863, No. 1,458.

To all 'whom it may concern:

Be it known that I, THOMAS RANDOLPH TAYLOR, of Cleveland, in the county of Cuyahoga and State of Ohio, have invented a new and Improved Machine for Forging Horse, Mule, and Cattle Shoes; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification, in which-- Figure l is a plan of the machine. Fig. 2 a Vertical section of the same, taken nearly in the planes indicated by the line m, of Fig. 1. Fig. 3 a vertical section of the same, in the plane indicated by the line y, y, of Fig. l. Figs. it, 5 and 6 are vertical sections of the dies on a larger scale than the other figures, illustrating the forging operaJ tion.

Similar letters of reference indicate cor4 responding parts in the several figures.

My invention consists in a novel system of dies, and in certain means of operating the same to forge a shoe with front and back calks by a continuous operation.

To enable others skilled in the art to make and use my invention I will proceed to describe its construction and operation.

A, is a strong bed plate, and B, C, D, E, standards erected upon it and combining with it to constitute the framing of the machine.

F is the horizontal main shaft of the machine working in a bearing on the standard D, and another on the standard E, fur nished with a fly wheel M, and geared by spur wheels F, G, II, and I, with the parallel horizontal shafts G, H, I, of which I works in bearings on the standards B, and D; G works in bearings a, a, resting on the bed plate, and H, works in bearings b, b, resting on the bed plate. The gears Gr, H, I, which all gear with F, are all of the same size, so that their shafts G', I-I, I', are all caused to rotate at the same velocity.

K and L are two horizontal mandrels arranged near the bed-plate in line with each other, but at right angles to the several shafts before described, and fitted to slide longitudinally in stationary guides c, c, and d, cZ. The mandrel K has secured to the end next the mandrel L, a male die N, the form of whose transverse section, shown in Fig. 2, corresponds with the intended form of the interior of the shoe; and the said die has square projections l0, l0, one on each side below the pointcorresponding with the length of the shoe, such projections being at a distance from the end of the said die, somewhat greater than the intended thickness of the shoe, as will be understood by reference to Figs. 5 and 6.

The mandrel L has secured to the end next the mandrel K, a female die O, the inside of which is formed to fit to the exterior of the male die N, and the exterior of which, is of the intended form of the outside of the slice; and the said female die has in its lower part two square recesses 1l, 11, one on each side, and a taper recess f, at the top where the front of the shoe comes. The recesses l1, 1l, are of such form that by the entrance of the male die into the female die with the shoe (which has been previously partly `formed by parts of the machine to be presently described) between their ends or faces, the projection 10, 10, on the male die will turn the back calks under the corners of the said recesses, as represented in Fig. 5, where the finished shoe is represented in blue color, and the back calks are indicated by the letters e, c. The recess f, is to operate in combination with means to be presently described to form the front calk which is indicated by the letter g, in Fig. l. The end of this female die is to be suitably formed for making the recess or groove, and the nail prints of the shoe.

The female die O, derives a regular reciprocating motion toward and from the male die, from a crank h, attached to the shaft G, the wrist of the said crank being received in a box z', (see Fig. 3,) that is fitted to slide in a straight vertical slot y', in the mandrel L, the advancing movement taking place during one half, and the retreating movement during the other half of every revolution of the said shaft. The male die N, also receives a reciprocating movement toward and from the female die, but this movement is effected during one half of each revolution of the shaft H, from which it derives motion, and the said die is stationary during the other half of the revolution of the said shaft, the suspension of its motion taking place after it has completed its advance. This movement of the said die, is produced by a crank 7c, on the shaft I-I, working in a semicircular slot Z, in the mandrel L, the said crank being so arranged relatively to the crank h, before described that the male die nearly completes its advance toward the female die before the ad vance of the latter commences.

P, is a broad slide, arranged to work vertically in guides m, m, in the standard C, with its face at right angles to the axes of the mandrels K, L. In the middle of the lower part of this slide,there is an opening m, large enough for the male die'to work freely through. To the outer face of the said slide'there are attached by two pins a, n, two similar swinging aws R, R, in the front part of each of which, there is a recess p, (see Figs. 2, 3, 4, 5 and 6) of the form of one half of the exterior of the shoe, such recesses extending back about two thirds through the said jaws, and at the back of each there is a smaller recess g, (see Figs. 2 and 4) which extends right through to the back of the said jaws, such smaller recesses being each of the size and form of one half of the interior of the shoe so that when the said dies are closed, the back of the recess formed by the combination of the recesses p, 79, is of the form of the upper side or face of the shoe. The said jaws being closed upon the male die, and the male and female dies being brought with the face or end of the female die at a proper distance from the back of the recess p p, the whole combine to form a mold of the intended form of the shoe.

In the front upper parts of the recesses 77, 79, there are small taper recesses 1", 1, which assist in forming the front calk, as will be resently described. Between the jaws R,

there is applied a strong spring S, which tends to force them apart, but is prevented forcing them very far, by means of two stops t, t, on the front of the slide P. The outer sides of the lower portions of the aws are beveled 0H in a wedge form as shown at u, u, in Figs. 2 and 4, for the purpose of enabling the jaws to be closed by the descent of their lower portions in contact with the beveled sides of a hole o, o, in the bedplate, as shown in Fig. 4. The portions of the said jaws which contain the recesses p, Z0, project some distance in front of the lower portions, and in the bottoms of such projecting portions there are grooves e, a, which serve as guides to the bar from which the shoe is made in the commencement of the forging or forming operation. The aforesaid slide P, has a slotted head P, in whose slot w, there works the wrist of a crank Q attached to the upper shaft I, for the purpose of producing an upward and downward movement of the slide, the form of the said slot and arrangement of the crank being such that the said slide is made to commence its descent soon after the mandrel K commences its advance and to continue its descent for some time after the said mandrel and the attached male die become stationary, but to remain stationary during the latter part of the time that the said mandrel is stationary, and during the latter portion of the advance of the female die, and to commence rising again simultaneously with the commencement of the retreat of the male and female dies N, and O.

T, is a xed cutter secured in a block T, bolted to the bed plate at the side of one of the jaws R, and having a vertical cutting edge. U, is a movable cutter, also having a vertical cutting edge, attached to a horizontal slide U', which works parallel with the mandrels K and L, through a guide in the standard C, and rests on the cutter block T. The said slide U', is connected with a horizontal lever V, one end of which is attached to a fixed fulcrum 7, and the other end by a pin 8, to the mandrel K, so that the cutter slide advances to cut oft' the bar, at the same time that the mandrel K advances.

The operation of the machine is as follows: Power being applied to the fly wheel M, by means of a driving belt, to give rotary motion to the shaft F, in the direction of the arrow marked upon the spur wheel F in Fig. 3, the shafts G, H, I, are caused by the gearing to rotate in the direction of the arrows marked upon their spur wheels, and the several parts of the machine are caused to have the relative movements already described. Every time the slide P, is raised the bar 9, from which the shoe is to be made, having been previously heated, is pushed by the attendant of the machine in the direction of the arrow shown near it in Fig. 2, throu h the groove 12, in the top of the cutter slide U', and through the grooves e, z, in the jaws, as far as is necessary which may be regulated by a suitably arranged stop. The mandrel K, then advancing with the male die, brings with it, the cutter slide U', and cutter U, and so effects the cutting off of the piece to form the shoe. The jaws R, R, immediately afterwards, descending with the slide P, receive the rim in the front or outer part of their recesses p, p, and so bend it over the male die, closing as they enter the opening w, o, of the bed plate, and'so closing the heel part of the shoe over the lower part of the male die, and swaging the iron so as to force a suflicient portion of it upward into the small recesses fr, as shown at 18, in Fig. 6, to form the toe calk. The jaws then remain firmly closed, while the mandrel L advances with the female die, and drives the partly formed shoe back along the outside of the male die till it arrives at the back of the recess p, p, by which part of the operation, the ends are turned up as shown in Fig. 2 to form the heel calks e, e, and the portion 13, which was swaged up into the recesses 1, r, of the jaws is turned back into the recess j, to form the toe calk g, and the crease and nail prints are made, thus completing the shoe. The die N, is then withdrawn, and such withdrawal being immediately afterwards followed by the ascent, and consequent opening by the spring S, Vof the jaws R, R, and afterwards by the retreat of the female die O, the shoe is released and drops through the opening o, o, in the bed plate, leaving the parts of the machine in condition to commence their operation again, when the piece of iron is fed into the machine again as before described.

The same machine can be used for mule or cattle shoes, by making the dies of proper shape; two cattle shoes being made from each piece of metal that is fed in, but being left joined at the toes to be afterwards cut apart. hat I claim as my invention and desire to secure by Letters Patent isl. The combination of a reciprocating male die N, a reciprocating female die O, and a pair of recessed reciprocating and swinging jaws R, R, the whole arranged and operating in relation to each other substantially as herein described.

2. The combination of the projections 10, 10, on the male die and the recesses 1l, l1, in the female die, operating together substantially as described to produce the heel calks on the shoe.

3. The combination of the recesses 1^, r, in the swinging jaws R, R, and the recess f, in the female die O, said recesses operating in conjunction with the other parts of the jaws and female die as described to produce the toe calli.

4:. Effecting the closing of the swinging jaws R, R, by their descent into an opening o, o, in the bed plate of the machine substantially as herein described.

5. rlhe attachment of the movable cutter U, to a slide U', arranged and operated by the mandrel of the male die N, substantially as herein specied.

THOS. RANDOLPH TAYLOR.
