JOHN R. WILLIAMS, OF JOHN STOWN, PENNSYLVANIA, ASSIGNOR TO OAMBRIA IRON COMPANY.

HORSESHOE-BENDING MACHINE.

SPECIFICATION formingpart of Letters Patent No. 225,257, dated March 9, 1880.

Application filed December 19, 1879.

To all whom it may concern Be it known that I, JOHN R. WILLIAMS, of

Johnstown, in the county of Cambria and State of Pennsylvania, have invented a new and Improved Machine for Bending Horseshoe-Blanks, of which the following is a specification.

My improvement consists, essentially, in constructing the former-bar with pockets for the reception of the toe calks, and the consequent adjustment of the bar to the bending devices, as hereinafter described.

In order that my machine may be fully understood, I will proceed to describe it with reference to the accompanying drawings, in which Figure l is a plan of the machine. Fig. 2 is a side elevation thereof. Fig. 3 is a transverse section on the line 3 3, Fig. 1, but showing the bending-rollers opposite one of the formers.

A A represent formers fixed to a center bar, A attached removabl y to the bed B. The said formers correspond in their external contour with the desired shape of; the interior of the shoe.

0 O are studs fixed in slides D D, pivoted to a cross-head, E, from which they receive a reciprocating motion. The studs 0 carry flanged rollers F F, and are confined to the required path by external guides, G G, which are made adjustable by set screws H H and clamp-screws l 1, and, like the formers A A, may be changed when required to adapt them to produce shoes of any desired size or style, (t (t and g 9 showing bolts or screws by which the center formers and external guides, respectively, are secured in position. The rollers are also changeable to suit the varying contour of the different kinds of shoes which it may be desired to produce.

In order to prevent wear on the outer side of the studs 0, sleeves or rollers c, of hard steel, are placed thereon, so as to roll on the surfaces of the guides.

. The formers are preferably arranged in the machine front to front, as shown.

In operation, the slides D D being in the position shown in Fig. l, a suitably prepared and heated blank is laid across the "machine, with the center of its rear edge against the front of the former A, and its toe-calk resting in a pocket, I), in the bar A which thus forms a gage to center the blank. The movement of the slides then carries the bending-rollers F F against the front of the blank, the flanges f of the rollers holding the blank firmly down to prevent it rising off the center former, and as the rollers are confined laterally by the guides G G, parallel with the proper external contourof the shoe,theblankis pressed closely against the former A completely back to the heel. On the return stroke of the slides, another blank being placed against the front of the former A, it is bent in like manner.

By the use of formers in pairs, as shown, the

machine is adapted to do double work, as the attendant readily places a second blank in po' sition while the first is being bent.

I am aware that it is not new to arrange formers and forming-rolls so as to bend a shoeblank at each reciprocation of the pitman connecting said formers with the motive power of the machine. I therefore disclaim such subject-matter, my invention constituting an improvement thereon.

What I claim as my invention is- The former-bar A constructed with pockets b for the reception of the toe-oallks, and consequent adjustment of the bar to the bending devices, substantially as and for the pur pose set forth.
