MACHINE FOR STRETCHlN-G AND FINISHING SHOES.

SPECIFICJsTION forming part of Letters Patent No. 355,966, dated January 11, 1887.

Application tiled October 27, 1886. Serial No. 217,304. (No model.)

To aZZ wliom it may concern.-

Be it known that I, IRVING E. BOOTH, a citizen of the United States, residing at Bochester, in the county of Monroe and State of New York, have invented a certain new and useful Improvement in Machines for Stretching and Finishing Shoes; and I do declare that the following is a full, clear, and exact description of the same, reference being had to the draw ings accompanying this application.

My improvement relates to machines for treeing and shaping the legs of shoes, and is of that kind where stretchingjaws are used, over which the ankle portion of the shoe is fitted, said jaws being then expanded until all the wrinkles in the shoe-upper are drawn out smooth, so that it can be malleted, boned, or ironed out.

The invention consists in the following construction and arrangement:

In the drawings, Figure l is a plan view of the machine in the closed position. Fig. 2 is r a side elevation of the same. Fig. 3 is a rear end view enlarged. Fig. 4 is an enlarged crosssection in line a: a; of Fig. 1. Fig. 5 is an enlargedcross-sectiou of one edge of the rim and turning-head in liney y of Fig. 3. Fig. 6 is an enlarged side elevation of the brush. Fig. 7 is an elevation of the lever that supports the outer ends of the expanding-jaws.

A A indicate the jaws, which consist of flat steel plates, which are of the usual or required form and of such shape as to easil enter the boot or shoe leg and, when expanded therein, fill out the leg at the edges. The jaws are connected with suitable supporting devices or bearings whereby they can be turned over or inverted.

The devices shown in the drawings consist of circular heads B B, which rest and turn freely in circular rims O O, forming the stationary standards of the machine. The heads are held in place by any suitable means, that shown being studs or levers a a, that rest in slots b b of the rim, said slots being of such extent that the studs have a motion of half a circle therein, the front stud being extended past the frame or standard of the machine to serve as a handle by which the jaws may be inverted.

Thejaws proper, A A, are provided with rear extensions or plates, A A, which rest in crossslotsc c of the heads, the slots being of such extent that the jaws can be moved out laterally to the proper degree to stretch the upper after the shoe has been placed over the jaws. By this means, after one side of the upper has been malleted or ironed, a half-turn of the heads will reverse or invert the jaws, so as tobring the other side of the shoe up, when it can be nialleted or ironed without releasing the jaws or removing the shoe, which has to be done in ordinary machines of the kind.

The jaws are operated by the following means:

D is a cross-bar resting loosely over the extension-plates A A of the jaws, just back of.

the front head, and sliding freely forward and back. (1 d are longitudinal slots in the plates, extending angularly inward as they extend back, as shown in Fig. 1.. The cross-bar has studs, on which are friction-rollers f f, that rest in the slots. When the cross-bar is drawn back, the studs running in the inclined slots will force the plates outlaterally, as indicated by dotted lines; Fig. 1. \Vhen pushed forward, it will close the plates together. E is a shaft attached rigidly to the crossbar, extending longitudinally back between the plates, and having at its rear end an arm, g, to which is attached a long spiral spring, G, that passes freely through a hole, h, of the rear head B, and is attached at its front end to a lug, i, of the front head B. WVhen the shaft is drawn back to expand the jaws, the spring G will be stretched, and when the shaft is released the spring will draw it back to place again and stretch the whole leg of the shoe.

back, as before described. 0 0 are cross-slots in the rear ends of theextension-plates of the jaws, and p p are studs rest-ing therein, said studs being attached to the inner side of the rear head I3. These studs, resting in the slots, prevent any longitudinal movement of the aws.

1 1" are elbows attached to the rear end of thejaws or of their extension-plates A A, outside of the head B, and sis a spiral cross-spri ng attached to said elbows. The tendency of the spring is to draw the jaws toward each other, but to be stretched when the j aws are expanded. At the commencement of the expanding action the front ends of the jaws expand first; and fill the lower-part of the leg, owing to the greater leverage at the front and the tension of the cross-spring s at the rear, which resists expansioirat that point. Then as the pressure is applied the jaws expand at the rear and For dressing some kinds of shoes a curved form or pattern, I, is pivoted at c to onejaw, as shown in Fig. 1, which by having a free turning motion 011 its pivot fits more accurately to the interior of the front portion of the leg and produces a better stretching action. This is of especial service in shoes that have a good deal of curve in the ankle.

In use the ankle portion of the shoe is placed over the ends of the jaws, and the jaws are eX panded,asbeforedescribed. Theupperisthen malleted, orotherwise operated on, the jaws themselves serving as an anvil and resisting the force of the blows. In most work the jaws are sufficiently stiff for the purpose; but in some cases, where heavy blows are to be struck, a lever, K, is used under the outer end of the jaws,-pivoted to a standard, w, andturning up under and in contact with the shoe when it is on the jaws, and held by a catch, a, of any suitable kind. The lever K is provided with a depression, or, at or near its center, whereby it will pass under and not bear upon buttons of the shoe. WVhen one side of the shoe has been dressed, thejaws are inverted or turned bottom upward, as before. described, and the other side dressed in the same'manner.

One great advantagein this invention is the jaws mounted in reversible bearings,whereby they can be inverted, so that both sides of the shoe can be operated on without releasing the pressure or removing the shoe from the stretching-jaws.

L is a brush used for rubbing and polishing the shoe after it .has been malleted. It is mounted on ashaft, j, which receives rotary motion by means of aband running on a pulley, e. The shaft rests in bearingst t of a yoke, M, and the latter is pivoted to a standard, N. By this means vertical motion is allowed the brush to bring it to or from its work.

The brush can be made of sufficient length to sweep the entire width of the shoe at one stroke, or it may be given a longitudinal motion through its bearings t.

The standard M has an offset, .2, pivoted at q to the base-plate P, by which the brush can swing horizontally to operate over the whole surface of the ankle portion of the shoe.

\Vhen not in use, the brush can be swung up out of the way, in which position the band is slackened and the brush ceases to revolve.

It is not material, except for compactness, that the details of construction shown in the drawings be followed in order that thej aws may be inverted or turned over. This part of my invention consists in the combination of a pair of stretching-jaws and suitable supports by which the jaws may be inverted or turned over, and is notlimited to the specific arrangement shown.

Having described my invention, I claim- 1. In a machine for stretching and dressing shoes, the combination of a pair of flat stretching-jaws, one or more supports therefor, and means, substantially as described, for separating thejaws, the saidjaws projecting beyond and clear of their supports, and separating mechanism, whereby the entire surfaces of the jaws remain unobstructed and constructed to serve without additional means the double purpose of stretching-jaws and an anvil. on which the malleting and finishing operations may be performed, as set forth.

2. In a machine for stretching and dressing shoes, the combination of a pair of stretchingjaws, one or more supports or bearings, and means, substantially as described, for separating the jaws, the said jaws projecting beyond and clearof the supports and separating mechanism, and adapted to be turned or reversed in position by means substantially as set forth, whereby both sides of the shoe may be operated on while remaining stretched, and without removing it from thejaws, as set forth.

3. In a machine for stretching and dressing shoes, the combination of a pair of stretchingjaws, one or more supports or bearings, substantially as set forth, adapted to be turned over or reversed in position with the jaws therein, and means, substantially as described, for separating the jaws in the said supports or bearings, for the purpose set forth.
