MACHINE FOR FINISHING CAST HORSESHOES.

SPECIFICATION forming part of Letters Patent No. 424,890, dated April 1, 1890.

Application filed July 19, 1889. Serial No. 317,975. (No model.)

To @ZZ whom t may concern:

Be it known that I, CHARLES J. LE ROY, of the city of St. Louis, in the State of Missouri, have invented a certain new and useful Improvement in IIorseshoe-IVIachines, of which the following is afull, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, and in whichm Figure l is a front View of my improved machine. Fig. 2 is a rear view. Fig. 3 is a side elevation. Fig. 4 is a detail View showing the cam for lifting the swage, and shows, also, part of the frame of the machine. Figs. 5 and 6 are sections taken on line 5 6, Fig. 7, and showing the die and the shoe formed upon it. Fig. 5 represents the shoe in the position before it is swaged and punched, and Fig. 6 the position it occupies with relation to the die after it is swaged and punched. Fig. 7 is a horizontal section taken on line 7 7, Fig. l, the die-formers and table being seen in top view. Fig. S is a detail perspective view of the die.

My invention relates to a machine upon which a finished horseshoe is produced from a blank; and my invention consists in features of novelty hereinafter fully described, and pointed out in the claims.

Referring t the drawings, l represents the frame of the machine, and 2 the bed-plate or table. At the inner end of the bed-plate or table is a die havingaraised part 3, which in shape and size conforms to the contour of the inside of the finished shoe, and upon this die the shoe is first formed and is then swaged and punched. Outside of the portion 3 of the die are ledges 4, (see Figs. and 6,) and between the surfaces 4 and the portion 3 the die is grooved out, as shown at 5, forming the swage.

At the bottom of the groove 5 is a rib 6, and

. in this rib is placed at intervals projections is provided with a driving-pulley 16. (See Fig. 2.) It will thus be seen that as the machine is operated the cross-head S will be moved to and from the die. Fitted to the cross-head S at 17 are formers or levers 18, having rollers 19 secured to their inner ends and rollers 2O secured to their outer ends.

21 represents a Shaper secured tothe table 2, as shown in Fig. 7. On the shaft 13 is a pulley 22. (See Figs. 2 and 7 and dotted lines, Fig. 3.) J ournaled in the upper end of the frame l is a shaft 23, provided with a pulley 24, connected through means of abelt 25 to the pulley 22. ,On the shaft 23 is a cam 26.

27 represents 'a hammer secured to the lower end of a rod or stem 28. On the upper, end of the rod or stem 28 is a pin or projection 29, engaged by the cam 26.

Pivoted to the frame 1 of the machine by means of a rod 30 are arms or levers 31, which are illustrated best by dotted lines in Fig. 3, but which also show in Figs. 1 and 2. To the inner ends of these levers a plate 32 is secured, and projecting upwardly from this plate are pins 33, which pass through perforations in the die. On the outer end of the levers 3l` are friction-rollers 34, engaged by cams 35 on the shaft 13.

The operation of my improved machine is as follows: After the blank has been cast andv is in the form of a'straight bar, either with or without the toes and calk and-with the nailhead grooves, it is placed on the table 2 at the outer end of the die, as shown by dotted lines A, Fig. 7. The cross-head 3 at this time is in its outer position, or the reverse position to that shown in Fig. 7. The shaper 2l is at this time holding the inner ends of the formers 18 close together, as shown by dotted lines B, Fig. 7, and is holding the outer ends of the formers apart, as shown by dotted lines O, Fig. 7. The machine now being set in motion, the cross-head 8 moves toward the die, carrying the formers 13 with it. As the formers bend the shoe around the raised central portion 3 of the die their inner ends have first an outward as well as a forward movement, while their outer ends are traveling over the surface D of the Shaper. They neXt have a substantially forward movement IOO only as their outer ends are moving over the portion E of the Shaper, and then their inner ends have an inward as Well as a forward movement as their outer ends are passing over the surface F of the Shaper. The effect of this is to bend the blank around the raised portion 3 of the die and produce the contour of the shoe, the Shaper imparting to the inner ends of the formers a movement that corresponds to the shape of the die, as will be plainly understood. Vhile the machine is making this movement the cam 26is turning in the direction indicated by the arrow in Fig, 1, and just as the formers complete their movement the cam leaves the projection 29 and the hammer 27, which has been thus lifted by the cam, falls upon the shoe, forcing it from the position shown in Fig. 5 to the position shown in Fig. 6, thus swaging it by forcing it down into the groove 5 and causing the rib G to enter the nail-head groove of the shoe and the projections 7 to form the nailholes. Therib 6, enteringthe nail-head grooves, which were east in the blank originally, opens out the grooves, which have been partially closed by the bending of the blank around the raised portion of the die. As the machine continues to move the formers and hammer recede, and the shoe is lifted out of the die by means of the pins 33, levers 3l, and cams '35,the cams depressing the outer ends of the levers, which causes the pins to move upwardly and lift the shoe from the groove 5, when it may be taken from the machine by hand. Thus the operation of the machine producing the forming, swaging, and punching of the shoe goes on continuously and automatically and produces the finished article with a small expenditure of time and labor. The die simply lits in a recess of the table 2, and the Shaper 2l is bolted or otherwise removably secured to the table.

It will be understood that the contour and size of the die and Shaper will be changed to correspond with the contour and size of the shoe to be formed.

I claim as my inventionl. In a horscshoe-maclline, the combination of a die having a raised portion, formers, a

shaper for adjusting the formel-s to the contour of said raised portion, and a hammer to swage and punch the shoe in said die, Substantially as and for the purpose set forth.

2. In a horseshoe-machine, the combination of the die having a raised central portion, a cross-head, mechanism for moving the crosshead, formers pivoted to the cross-head for forming the shoe around said raised portion, a Shaper against which the outer ends of the foi-mers bear, a hammer to swage and punch the shoe in the recess in the die after pressing the shoe down from said raised portion, and a cam for lifting the hammer, substantially as and for the purpose set forth.

In a horseshoe-machine, the combination of the table or bed-plate, a removable die f1tting in a recess in said table, a raised central portionv to said die, formers, means for adjusting the formers to the contour of said raised portion, around which latter the shoe is bent, and a hammer to swage and punch the shoe in said die, substantially as and for the purpose Set forth.

et. In a horseshoe-machine, the combination of the stationary die having a raised central portion and a grooved portion provided with ribs and projections forming a swage and punch, formers, means for operating the formers to adjust the blank to the contour of the die, and a hammer reciprocating above said die to force the shoe into the groove after it has been formed around said raised portion, substantially as and for the purpose set forth.

5. ln a horseshoe-machine, the combination of a die, means for bending the blank around the die, means for swaging and punching the shoe after it is bent around the die, and means for lifting the shoe out of the die, consisting of pivotcd levers, vertical pins moving through the die from below to project the shoe from the die and secured to the levers at one end, and cams for operating the levers, substantially as set forth.
