GEORGE J". GORSUCH, OF ROCHESTER, NEW YORK, ASSIGNOR TO UNITED SHOE MACHINERY COMPANY, OF PATERSON, NEW JERSEY, A CORPORATION OF NEW JERSEY.

VAMP-PULLING APPARATUS.

To all whom it may concern Be it known that I, Gnonen J. GonsUcH, a subject of the Emperor of Germany, residing at 7 Seager street, city of Rochester, county of Monroe, and State of New York, have invented certain Improvements in Vamp-Pulling Apparatus, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to vamp pulling machines and the machine herein to be described as exemplifying this invention is designed primarily for stretching the vamp of an assembled shoe preparatory to the presentation of the shoe to a pulling-over machine of the type shown in United States Letters Patent No. 663,777. It is found that many Vamps can with advantage be stretched lengthwise immediately prior to being subjected to the pulling-over operation, and 1t is the practice of some of the best pullingover machine operators so to stretch the upper after taking the shoe up for presentation to the machine. In some instances hand pincers are used by which the upper is seized at the toe end and pulled over the toe of the last. In other instances the operator grasps the forepart of the vamp the tip line with his hand and with this grlp he stretches or sets the vamp forwardly and down the instep slant of the last and then, while holding the upper so pulled and positioned or gripped by his fingers against the instep or ball of the last as best he can, he

- presents the shoe to the upper seizing jaws of the pulling-over machine.

A particular object of this invention is to provide an apparatus for use in effecting the operation just described and which shall be more powerful and more eifective than the operators hands.

An important feature of this invention consists in a rest against which the toe end of a last may be abutted and a pair of pincers arranged relatively thereto to selze the upper and pull it toward and over the toe. Either the pincers or the toe rest may be actuated in the direction to stretch Specification of Letters Patent.

the upper and preferably the pull on the upper will be a substantially straight for Patented June 25, 1912.

ward pull from the heel in about the plane i of the top of the forepart of the last. Preferably and in accordance with a further feature of the invention the abutment and the manually operated pincers will be arranged for the pincers to seize the vamp at a substantial distance back from the toe end and it may be at or back of the tip seam. Advantageously the pincer jaws will be long so that they will take in their throat the tip portion of the upper and preferably they will be wide so that the lines of strain will,

extend from either side thereof backwardly along the sides of the vamp as distinguished from narrow jaws which would concentrate the pull in the middle portion of the vamp.

Another very important feature of this invention is found in the provision of means to rest upon the upper that is being pulled and move with the pincers while they are stretching the vamp. This means may have a rubbing action over the stretching upper and in the illustrated apparatus it has a useful function in bending the upper out of the straight line and down into the curve at the base of the instep. As herein shown this means is a plate carried by one of the pincer jaws and extending forwardly therefrom to engage the upper in advance of the gripped area. The plate has an adjustable connection with the jaw and a forked front end with a member to engage the vamp at each side of the shoe. These fork members may be bent down in conformity with the general shape of the last. This upper engaging plate, in the illustrated apparatus, cooperates with the pincers in preparing the upper for presentation to the pullingover machine by bending the vamp down toward the face of the last. When the shoe is in this condition with the upper pulled forwardly on the last the operator seizes the shoe in his hand, gripping the upper to the last with his fingers and thumb and, after releasing the pincers, he turns the shoe sole uppermost and presents the shoe to the grippers of the pulling-over machine as in Fig. 7 9 of the patent mentioned.

These and other features of this inven tion, including numerous details of con struction and combinations of parts, will appear in connection with the following description of the illustrated apparatus and will then be pointed out in the claims.

Referring to the drawings, Figure 1 is a side elevation; Fig. 2 is a detail plan; and Fig. 3 is a plan View.

The apparatus is shown as a bench machine worked by a treadle. The lower pincer jaw 2 is a bar sliding under guides 1 which are bolted through the spacing plate 6 to the table 5. Through the guides 4 also slides the bar 10 to the front end of which is pivotally connected the long aw 12. The ribbed gripping faces of the jaws are carefully formed to avoid marking the upper. The jaw 12 is also connected by parallel inclined links 14: with the jaw 2 and from jaw 12 depend links 16 having pin and slotconnections 18 with the jaw 2 and a pivotal connection with the eccentric head of a closing lever 20. Turning movement of the head of this lever toward the right in Fig. 1 draws downwardly on the aw 12 to close it on stock which may have been interposed between the jaws. This downward pull on jaw 12 also acts through the links 1 1 to cause that jaw to close with a movement toward the right or toward the body of the shoe.

The jaw closing lever 20 has connection with a fork 22 having outturned ends 23 and this fork embraces the bifurcated arms of a rod 25. These arms have inturned ends 26 and each fork and arm which are in sliding engagement wit-h one another is encircled by a compression spring 28 which provides a yielding element permitting variations in the thickness of stock with a jaw closing mechanism which has a constant stroke. The rod 25 is connected to a rocker 30 which is pivotally suspended from the table 5 and is pressed by a spring 32 forwardly into a recess in a cam disk 35, which is mounted to rotate in hangers 36 depending from the table. This cam disk is connected by a lever 10 with a treadle rod 42 and treadle 45, being fulcrumed on a strut or brace 44; one end of which is pivoted to the hangers at 46 and the other is pivoted to the lever at 48. Depression of the treadle causes the strut 4A: to turn about pivot 46 and causes the lever to fulcrum on pivot pin 48 and also to pull forwardly on cam disk 35 and force the rocker 30 backwardly to close the pincers on the work. A return spring 19 assists in reversely moving the parts when the treadle is released as does also the spring 32 and the jaw opening spring 11, and a jaw advancing spring 3 that is in the rear end of the bar 2.

The pull on the jaw closing lever 20 is in the direction to move the jaws longitudinally to stretch the upper over a last the toe end of which is rested against the con cave faced abutment 50 that is fastened to the table for adjustment lengthwise of the machine. The cam disk has, however, asecond recess into which projects a stud 52 from pincer bar 2 into position to be picked up by the cam disk in the last part of its oscillation and effect more positive movement of the jaws to stretch the upper. The long pincer jaws receive the tip of the shoe in their throat and seize the vamp at about the tipseam or it may be farther back according to the adjustment of the abutment 50 which is held in place by screw 54 and slot connections with the table 5 that also serves as the bottom rest or sustainer for the last.

Aflixed to the upper jaw 12 by a screw 58 and slot connection is the plate 60 which is curved downwardly and is forked to engage the upper in advance of the aws and press it toward the face of the last and into the curve or depression between the base of the instep and the toe. This plate is actuated by the jaw 12 and moves with it with a slight rubbing action over the upper. The plate may be resilient and may or may not press the upper against and clamp it upon the last at the ends of the fork.

In the use of the apparatus the operator places an assembled shoe as shown in Fig. 1 and depresses the treadle to pull or stretch the upper the amount required for the particular shoe in order to prepare it for the pulling-over operation. As the jaws are closed the plate 60 is brought down upon the upper, having been first adjusted lengthwise for the length of the shoe, if required, to press the latter down toward and, it may be, against the top face of the last. The plate moves in contact with the upper as the jaws are retracted for stretching the upper. Before releasing the treadle he seizes the shoe with his right hand, grip ping the forepart of the vamp to the last and then permits the pincers to open. with the shoe so held he lifts it and presents it to the pulling-over machine adjacent to which this upper pulling apparatus will be stationed for this use. the shoe is the normal one for inserting the upper into the gripper jaws of the pullingover machine which is then started to seize the upper and stretch it, particularly about the forepart of the last.

The formation of the plate 60 has the advantage that it enables the operator to engage the vamp on the top of the last with his thumb or forefinger in the fork, as may be seen from Fig. 3, to clamp the vamp to the last before releasing the pincers and thus prevent the vamp from sliding up the instep incline again. The plate 60 is so related to the toothed face of the upper jaw This presentation of 12 that the plate guides the upper into the pincer awe and tends to prevent the upper from catching upon the teeth, as may be seen in Fig. 1.
