HEEL=STIFFENING MACHINE.

SPECIFICATION forming part of Letters Patent No. 392,975, dated November 13, 1888.

Application filed January 16, 1888. Serial No. 260,881. (No model.)

To all whom it may concern:

Be it known that I, EUGENE H. TAYLOR, of Lynn, in the county of Essex and State of Massachusetts, have invented certain new and 5 useful Improvements in Machines for Forming Heel-Stifieners, 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 apper- 1O tains to make and use the same, reference being had to the accompanying drawings, and to letters of reference marked thereon, which form a part of this specification.

My invention relates to improvementsin r 5 machines for forming heel-stiffeners for boots andshoes, andparticularly to those parts of .such machines as are immediately concerned in forming or molding the stiffener from the blank of leather.

The general purposes of this invention are, first, to turn the flanged part, crimp it, and then render it smooth and permanent by pressure, and, second, to press and polish the forward parts or sides of the stiffeners.

In the accompanying drawings, Figure 1 is a front elevation of my machine. Fig. 2 is a plan of the mold, bed-plate, former-crimper, and sliding plate. Fig. 3 is a side sectional elevation showing sliding cross-head, toggles, 3o toggle-joints, mold, former-crimper, and finishing-crimpemand Fig. 4. is a bottom plan of the finishing-crimper.

In all these figures same letters refer to like parts.

In the figures, F F represent the sides of the framework, and B the crossconnectiomwhich serves also for a bed or table for the moldblock and slide that carries the former. The sides F F are slotted to receive the tenons of the cross-head H. The cross-head H carries on its under side the finishing-crimper D. In the top of the table or bed-plate B is a slide, S, adapted to move backward and forward in a dovetail groove, and carrying on its face the 5 horizontal plunger S. Attached to the table Bby bolts passing through the projecting arms f and said table is the mold block M, in which is the mold 0, adapted to receive the former S and a heel-stiffener blank placed on the with gearing in such way as to impart to it a reciprocating motion. The upward and downward motion of the cross-head H and toggles T give a reciprocating horizontal motion to the slide S, which is regulated so as to carry the former S into the mold O in its forward motion and to withdraw it from said mold in its backward motion.

In connection with the mold O, the l1orizontal former S, and the vertical plunger P, various devices have been employed to turn over and form the flanged part of the heelstiffener. None of these devices has proved entirely satisfactory; An illustration of attempts of this kind may be seen in patents granted to Elbridge S. Mansill, November 14,

1882, Nos. 267,438 and 267,439, of which ma-- chine my invention is animprovement.

To turn the flanged part of the heel-blank accurately and uniformly, I make use of the following improved method: At or near the open end of the mold O, I attach to the sides of the mold-block M a plate or crimper, an, extending over and across the mold, as shown in Fig. 2. The crimper may be made adjustable by having the attaching-bolts run in slots tin the extended parts 1? of said plate n. I do not confine myself to any particular form or shape of the crimper-plate n. The essen tial feature of my invention is acrimper-plate placed above the mold, and under which the former, with the blank on the end thereof, must pass as it enters the mold.

The operation of this part of my device is as follows: The former S being withdrawn from the mold, as seen in Fig. 2, the blank is placed in front of it and between it and the mold. As much of the blank as it is desired to turn over to form the flange of the stiffener extends above the face of the former S. The face of the former is nearly level with the face of the mold-block, and consequently with the under surface of the crimper a. When the crosshead H descends, the slide S, carrying the.

former S, with the blank placed as just described, is drawn forward into the mold,passing under the crimpcr n. As the blank passes under the crimper n the part thereof which projects above the face of the former is turned over and down upon the face of the former. The former continues to enter the mold until the blank is firmly pressed between the end of the former and the inner end of the mold. At the same time the finishing-crimper D descends upon the turned edge or flange of the blank and firmly compresses it between the face of the former and the face of the finishingcrimper. The former is then, by the upward motion of the cross-head and toggles, withdrawn from the mold, and the blank, duly formed into a stiffener, may be taken out.

It is of advantage to firmly press the sides of the stiffener and to give them a more solid texture and a smooth polished surface. This I accomplish by making the mold 0 considerably longer than the length of the sides of the stiffener-blank when bent around the end of the former. The sides of the stiffener are thus pressed between the former and the sides of the mold as it is drawn into the mold. The continued movement of the stiffener pressed against the sides-of the mold tends to force the particles more firmly together, and by the friction between the side of the blank and the sides of the mold the outer surface of the sides of the stiffener is polished.

I disclaim the combination, with a die or mold and a series of pivoted crimping-levers and vertical plunger, of a longitudinal plunger and operating mechanism, as described and claimed in patent to Elbridge S. Mansill, November 14, 1882, No. 267,438.

Having thus described my invention and its use, what I claim, and desire to secure by Let tors Patent of the United States, is-

The combination, in a machine for forming heel-stiffener blanks, with the fixed block M, having mold or female die Oand flange-turning plate a, sliding plate S, carrying male die S, and suitable machinery for imparting a reciprocating movementto slide S, ofthe finishingcrimper D, attached to the cross-head H, and having its lower end adapted to enterthe die 0 behind the flange-turning crimper n, all substantially as and for the purposes hereinbefore set forth.

In testimony that Iclaim the foregoing as my own I affix my signature in presence of two witnesses.

EUGENE H. TAYLOR.
