CHARLES L. HAIGHT, OF POUGHKEEPSIE, NEW YORK, ASSIGNOR TO THE EAGLE HORSE SHOE COMPANY, OF WVISCONSIN.

HORSESHOE-FORMING MACHINE.

SPECIFICATION forming part of Letters Patent No. 539,427, dated May 21, 1895.

Application filed July 27, 1892. Serial No. l ls N 111 1 To all whom it may concern.-

Be it known that 1, CHARLES L. HAIGHT, of

- Poughkeepsie, in the county of Dutchess and State of New York, have invented certain new and useful Improvements in Horseshoe-Forming Machines; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

The main object of my invention is to facilitate the production of horse-shoes and reduce the cost thereof.

It consists of certain novel features in the construction and arrangement of parts hereinafter particularly described and pointed out in the claims.

In the accompanying drawings like letters designate the same parts in the several fig- UI'GS.

Figure l is a plan view of a machine embodying my improvements, the slide-retaining cap-plates being removed. Fig. 2 is a side elevation of the machine. Fig. 3 is an end elevation viewed from the left with reference to Figs. 1 and 2. Fig. 4 is a vertical crosssection on the line a: to, Fig. 2, looking from the right. Fig. 5 is a perspective view, on an enlarged scale, of one of the swage-slides and Fig. 6 is a similar view of the forming-die as seen from the under side.

A is a reciprocating slide, movable horizontally in ways provided for it in the frame N. It is connected at one end by a rodor pitman a, with the crank b, on crank shaft B, by which it is actuated. To the opposite endof said slide is rigidly and detachably secured by a bar 0, the forming die 0, the contour of which corresponds with that of the inner curved edge of the shoe it isintended to form. On the upper side said die is formed with ribs 0 0', between which the bar 0 is bolted and securely held, and around its edge it is .formed with anoutwardly projecting flange 0 which holds the blank in place, preventing its upward deflection and displacement while it is being formed into a shoe.

D D are two horizontally reciprocating slides movable parallel withthe slide A in suitable ways in frame N and provided at one end with swaging dies 61 d, which are held in recesses therein by plates d 01 screwed to said slides. The slides A and D D are held in place in their ways in frame N by cap plates 11. n

. move a limited distance vertically, the enlargements e e turning in the recesses in which they are held.

Upon a horizontal shaft F supported in brackets f on the base of the machine frame N, are mounted two bell crank levers G G, the upwardly projecting arms of which bear loosely against the friction rollers e e. The horizontal arm g of each of said levers is provided on the under side of its free end with a friction roller g, in range with a cam H on a rotary cross shaft 1. 7

Each slide D is formed in its upper side with a T-shaped recess in which is inserted and held the similarly shaped flattened end of a rod J, supported horizontally in bearings in frame N and provided with aspiral spring j, bearing atone end against a nut thereon and at the other against the frame.

Opposite the dies d cl, two dies It is, are adjustably held transversely to the movement of slide A against abutments K on frame N by cap plates is At the opposite end of the machine from the crank shaft B on opposite sides of the path of the die 0, are two lovers L L, fulcrumed at intermediate points therein on pins ZZ, secured vertically to frame N. Said levers are provided at opposite ends with ben'ding rollers Z Z and friction rollers Z Z The pins on which the rollers Z Pare journ'aled, pass through transversely slotted openings in levers L L, and are adjustably held therein.

Aand die 0, is aslide M,to which is attached IOO adjacent to rollers Z Z a wedge block on. A screw threaded striking rod m is adjustably held by nuts m in upturned perforated ears on the upper side of said slide M, in line with the bar 0.

A spring Z connects the levers L L between the fulcrum pins Z Z and rollers Z Z and holds said rollers in engagement with the opposite inclined or curved sides of the wedge block m.

represents the driving shaft provided with a suitable pulley o, and with a pinion 0', which engages on one side with a gear P on crank shaft 13 and on the other with a gear Q on cam shaft I.

It will be observed that the several shafts B, F, I and 0 have their bearings firmly and rigidly supported either upon the base or top of frame N, in such a manner as to most efficiently resist the strain to which they are subjected.

Channels 17. n, are formed in the frame N between the dies (Z d and 7.: 713, to receiveand conduct off scales loosened from the blanks and to prevent accumulation of such scales and consequent clogging of the machine.

My improved machine operates as follows: The driving shaft 0 being rotated in the direction indicated by the arrow in Fig. 2, turns the crank shaft B and cam shaft I through the intermeshing pinion o and gears P and Q in opposite directions also indicated by arrows in the same figure. The forming die 0 attached to slide A is thus driven back and forth between the inner ends of the dies 7t 70, and the rollers Z Z in the adjacent ends of levers L L, by the crank b and connecting rod ct; and the dies d d, attached to slides D D are moved toward and. from the opposing dies 7t) 70 by the joint action of the cams I-I, bell crank levers G G, and the retracting springs jj on rods J J. The blanks or bars of iron of the proper length and size are placed as indicated by dotted lines in Fig. 1, one at a time crosswise upon a leaf or table n on frame N, with their ends between the dies dd and 7c k, which closing against the blank R as shown in Fig. 2, swage and form the heels of the shoes. The forming die 0 then advancing forces the blank between the inner ends of dies 70 k, which bend it around said die (3. The bar 0, striking the adjacent end of rod m on slide M, forces the wedge block in forward between the friction rollers Z Z thereby moving the bending rollers Z Z at the opposite ends of levers L L toward each other against the outeredges of the shoe and bending the heels inwardly against the contracted sides of the forming die (J, thus completing the shoe with the exception of the calks, nail holes and groove. When the slide A is Withdrawn, carrying the bar 0 out of contact with rod m the spring Z spreads the ends of levers L L, carrying the bending rollers Z Z and drawing the friction rollers Z Z together against the inclined or curved edges of the wedge block m, forces the slide M backward intoits normal position. As the forming die 0 passes backward the shoe is removed and drops therefrom through an 'opening in the bed of the machine.

The friction rollers e e connected by the vertically swinging roller blocks E E with slides D D, prevent friction between said slides and the bell crank levers G G, due to the arc motion of said levers and cause the machine to run with greater ease and less wear.

By the substitution of dies of different shapes and sizes and by the proper adjustment of such dies and of the friction rollers Z Z and striking rod 117/, shoes of various sizes and shapes may be made by the machine.

Various changes in the details of the machine may be made within the spirit and intended scope of my invention.

I claim- 1. In a horseshoe forming machine, the combination with a reciprocating forming die, of levers fulcrumed at points between their ends to the frame on opposite sides of the path of said forming die and provided at one end with bending rollers, a reciprocating wedge block movable independently of and in line with said forming die between the opposite ends of said levers to close said bending rollers against a blank on said forming die, and a spring connecting said levers and holding them in engagement with opposite sides of said wedge block, substantially as and for the purposes set forth.
