MACHINE FOR ROLLING HORSESHOE-BLANK BARS.

SPECIFICATION forming part of Letters Patent No. 349,950, dated September 28, 1886.

Applicaiicn filed August 1i, ISSG.

To all whom it may concern:

Be it known that I, HENRY CARTER Os'rme,

. the following is a specification, reference bei ug had to the accompanying drawings, in which- Figure l is an end View of my improved machine. Fig. 2 is a side View. Fig. S is a detached view of the bottoln roller. Fig. 4 is a detached view of the swagiug-roller. Fig. 5 is a section ofthe heel portion of a blank to be formed. Fig. 6 is a section through the creased part of the same; and Fig. 7 is a view showing a formal modification of the creasing and swaging rollers where they come iu contact.

The object of my invention is to provide a machine for rolling out a series of horseshoeblanks from a suitable bar 'for the purpose, and in the same rolling operation to do three things-to wit, iirst, to crease the blank; second, to thin it and bevel it without narrowing between the heel ends and on the opposite side to where the creases are; and, third, to swage the heel ends. This, as generally stated above, has been done before, but my machine is of peculiar construction for doing it advantageously and without some of the difficulties and imperfections that have heretofore existed.

Referring to the letters upon the accompanying drawings. A indicates the main frame or housings,which may be such as illustrated, or of any other ordinary or suitable character.

is a horizontal rollershaft, .mounted in ordinary journals in the main frame and carrying pinion U, collar D,which may be cast integral with the shaft, bottom roller, E, and bevcled pinion F.

G indicates another shaft in suitable bearings in the main frame, but inclined with respect to the shaft B, as illustrated. This shaft G carries the pinion H, collar I, and creasing-roller K.

L is ashaft perpendicular to the shaft B, carrying beveled pinion M and heel swag-ing roller N.

O indicates a front guide, provided with a feed-opening, l), with a flaring mouth, as usual.

Q indicates a rearor delivery guide, of usual construction.

Serial No. 209,853. (Nomodcl.)

The bottom roller, E, is provided with a collar, R, for forming the front edge of the shoe. The surface S of this roller is provided with depressions T to form the heel portions of the blanks. In this instance three are shown, but more or a less number might be provided, according to the size of the roll. These depressions permit the metal while being swaged at the hccl portions ofthe blanks by the operation of all thc rollers to thicken up, so that the desired nearly square form at the heels is attained. The general surface S of the bottom roller, B, it will be observed, is inclined inward toward the collar B. The ohject of this is to properly bevel the top part of the blank, which corresponds to the part of the shoe placed against the hoof of an animal. The creasing-roller K is inclined, like the shaft G, with respect to the bottom roller, E, and is arranged so as to crease the blank upon the edge next to the collar Pi. The result is as the collar B is integral with the roller E the creasing is done where there is nojoint for inning ot' the blank at the angle, which should be clean and sharp on the opposite side to where the creases are made. The swaging-roller N is provided with projections U, adapted to do the whole work upon the edge ot' the bar opposite to where the creases are made. These projections correspond in position and in operation come opposite to the depressions T in the surface of the roller E, and serve to form the nearly square heel portions of the blank. In the present instance three of these projections are shown; but more or alcss a number might be employed, according to the size of the swagingroller. This roller is beveled at V on its upper side, so as to be parallel with the periphery of the creasing-roller, which impinges against it.

Instead of bevcling the swaging-roller at V, it might be made plain and horizontal on its upper surface, and the crcasing-roller might be formed to lit it, as indicated in Fig. 7, the object being to usean inclined shaft and creasing-roller, but to get a close joint between the creasing and swaging rollers where they contact. It may be done in either of the ways mentioned, though I prefer to use a bevel on the top of the swaging-roller. Besides these peculiarities of construction, the roller N is ICO provided with an irregular surface of `projections and depressions, W, immediately beneath the bevel V, adapted to cause it to closely fit the irregular or eccentric surface S of the bottom roller, E. The concentric part X of the roller N bears against the side of the roller E and forms a tight joint. It will be seen that the collars D and I, being cast integral with the shafts B and G or fixed solidly thereon, and bearing against each other at their sides, as illustrated, serve to transfer the lateral strain from roller El to shaft G when the heel portions of the blanks are being swaged, so that the resistance of the fastenings of both shafts is availed of equally to support that strain. It will also be seen that when the creasing is being done there is a. great strain exerted between the collar R and the working creaserwhieh would tend to separate them. This strain is also resisted by the collars D and I.

It will be desirable in practice to make the rollers E, K, Iand N in sets corresponding in size to a given size and length of shoe-blank. I provide for taking off these rollers and putting on other sets ot' different sizes by making the bearings of the shaft G adjustable up and down, as usual.

One advantageof having the inclined shaft I is that when the sets of rollers are changed the inclined shaft can beadj usted up or down,
