SPECIFICATION forming part of Letters Patent No. 258,998, dated June 6, 1882.

I Application filed December 15, 1881. (No model.)

To all whom it may concern:

. Be it known that I, JOHN DEEBLE,of Southington, in the County of Hartford and State of Connecticut, have invented certain new and useful Improvements in the Art of Manufacturing Ox-Shoes, of which the following is a specification;

My invention relates to improvements in the art of manufacturing oX-shocs in which the shoe-blanks are first cut from a bar which is the width of two blanks for their whole length by dividing said bar lengthwise upon curved lines, after which the ends are upset to form the calks by heading the blanks under endwise pressure, and then the toe end is bent and the shoe creased. a r

The main objects of my invention are to.

avoid waste of stock, to. economize in labor, and make a better article.

In the accompanying drawings, Figure 1 shows a side view of a bar of iron having one end prepared. ready to divide into two blanks. Fig. 2 shows a side view of the dies for preparingthe end of said bar. Fig. 3 is a plan view of the die for cutting the blanks from the bar. Fig. 4 is a side view of a headedblank.

Fig. 5 is a face view of the heading-dies. Fig.

i 6 is a sectional view of the same on line :0 mot Fig. 5. Fig. 7 is aface view, showing a modification of said dies. Fig. Sis a sectional view of the same on line y y of Fig. 7. Fig. 9 is a face view of the creasing-die; and Fig. 10 is a plan view of the bender, in which the blanks are also held for finishing.

I first take a bar of iron, A, Fig. 1, of such width that the whole length of two blanks may lie side by side thereon. I prefer to strike the edges of this bar at one end before dividing the blanks into substantially the form of a truncated ova-l figure, with the curve of the edges conforming to the curve of the edge of the shoe at the heel end, as shown at B, Fig. 1. This may be done by a hand-hammer or otherwise; but the best way to do it is by means of dies 0 C, Fig. 2, having curved recesses a a, in which to place the bar while hot for operating on its edges; and the flatfaces of said dies may strike the bar flatwise, if de* sired, to reduce it to auniform thickness after operating on its edges. Thus preparing the end of the bar will avoid all waste of stock 3 but the bar might be divided, if desired, without thus preparing it, in which a case a portion of the bar will be trimmed ofiand wasted. I next place the prepared end B of the bar A over the die D, Fig. 3, with one edge resting against suitable gages, b, as indicated by broken lines. A punch whose Contour corresponds wit-h that of the'die D is then forced into said die, cutting the end of the bar to divide it into two blanks on the longitudinal curved lines 0 c and on the straight transverse line d, forcing the blank so cut off through the die D, and having a like-shaped blank upon the end of the bar. It is intended to have the edges of the prepared end of the bar so nearly conform to the shape of the die D that it will notdo any substantial cutting upon its other sides. The blank left on the end of the bar is then cut off in any proper man neras, for instance, by means of the chisel e. In case the bar was not previously prepared the die D would cut all around and both blanks should be forced through said die, or one cutting the blanks into the same shape. In either event the heel end of the shoe-blank is, so far as the direc tion of its curved edges is concerned, in substantially its final form, so thatit is afterward necessary to bend only the toe end.

The next step in the process is tohead the blank for forming the calks. This I do by means of heading-dies E E G, recessed to reeive and hold the blank F, and also further recessed upon one side, as atf, to form a matrix in which to mold the'calk under endwise pressure of the hammer or header die G. A machine similar to a bolt-header will answer for this purpose, and of course the end of the groove 0 in it to receive the blank, as shown in Fig. 6, and as indicated by broken lines in Fig.5. Said die also extends farther forward than the end of the blank to be headed .so as to prevent a fin from being thrown out upon the back side of the shoe at a point opposite thejunction of the calk and body. The header or hammer die G has a ridge, a, which fits into the blank-receiving groove 0 of the die E and the recessf. The swell on the blank, in connection with the curved side of groove 0, constitutes a gage by which to seat the blank in the proper position for heading in said groove, and for-the purpose 'of creasing the blank duringtheheading operation about halfthe length of the blank should be embraced by the dies E E. The movable die E is provided with a creasing-ridge,q, which, asthe blank is gripped by the dies E E, will also crease that end. Both ends of the blank will be headed or headed and creased in like manner, the dies for so doing being shaped to conform to the respective ends of the shoe-blank.

If desired, the movable die may also be so shaped as to partially round the inner edge of the blank and to flatten or thin out the ball of the shoe alittle while it is being gripped for heading.

If desired, the dies E E G may be changed by constructing them as shown in Figs. 7 and 8, in which the blank-receiving recess is made in the same die, E, as is the creasing-ridge q, while the confronting sides of dies E G are plain, except at the recessf.

'Heretofore the calks have been formed by first bending the ends of the blanks until they stand at right angles to the body thereof, and then upsetting or hammering down the calks by blows given transversely to the length of the blank instead of longitudinally. By my mannerof heading the blanks to form the calks all danger of forming cold-shuts is avoided.

Although I consider heading the blanks in the manner described the best way to practice my process, yet it is evident that if the calks were formed in the ordinary manner, in connection with the other steps of the process herein described, my invention would be employed. Afterthe blanks are headed or headed and creased they are bent at the toe end and finished. This I do by means of a flat bed, H, Fig. 7, having a ledge or shoulder, upon one side, against which the blank is forced by means of a lever, I. The broken lines in said figure indicate the position of the blank and lever when the blank is first placed on the bed H for bending, and the full lines show the blank and lever after bending. While the blank is thus held in the header the die or hammer, Fig. 6, having a creasing-ridge, h, is forced upon said blank to finish or perfect the form of the crease k. This hammer, Fig. 6, is provided with recesses mmto receive the calks on the blank, and they should be of suchdepth that their bottoms will bear on the top of the calks when the creasing-ridge is forced home, and thereby the whole blank will be leveled up during the finishing operation. The inside edge of the shoe or the ball may be rounded or beveled ofl'in any proper manner. This may be done, if desired, at the same time that the blank is creased.

In a former patent to myself, No. 145,633, dated December 16, 1873, the bar is divided into two blanks on lines which extend only partly the length of the blanks-that is, over the toe ends-while the whole width of the bar was consumed to form the heel end of the blanks, and the same is hereby disclaimed. In that patent one toe-blank was cut from the side of another toe-blank. In my present invention each toe blank is cut from the side of a heel-blank, and vice versa.

I claim as my invention 1. Thatimprovement in themanufacture of ox-shoes which consists in cutting two blanks from the width of a bar by dividing the toes from the heels on a line which extends the whole length of said blanks, bringing the edges at the heel end of the blank into substantially its final form ofcurvature, and then bending the toe end of the blank, substantially as described, and for the purpose specified.

2. That improvement in the manufacture of oX-shoes which consists in firstforming a blank in the shape of a truncated oval figure, then dividing it from end to end on a curved line, forming the calks thereon, and bending the toe end, substantially as described, and for the purpose specified.

3. That improvement in the art of forming oX-shoes which consists in first forming the blank with the edges of its heel end having substantially the same curvature as that of a finished shoe, then forming the calks thereon, then bending the toe end, and finally striking the sameto finish it, substantiallyas described, and for the purpose specified.

4. The heading-dies having the calk-forming recessf for forming the calk under pressure and acting longitudinally with reference to the length of the blank, substantially as described, and for the purpose specified.
