Application filed September 17, 1914;. .eria1N0. 862,193.

To all whom it may concern Be it known that T, SAMUEL 1. Dana, a citizen of the United States, and a resident of Emails, in the county of Lehigh and State of Pennsylvania, have invented a new and Improved Clamping and Holding Means for Shoe-Uppers, of which the fol lowing is a full, clear, and exact description.

This invention relates to improvements in clamping devices for shoe uppers and has for an object to provide a device for clamping and holding uppers preparatory to marking the spaces for buttons thereon.

A. further object in view is to. provide an improved construction which will engage and hold the uppers properly in position while the same are being marked.

Another object of the invention is to provide a holding device for the button lap and outside quarter of a shoe which has a double movement, one for grasping the outside quarter and button lap and the other for forcing the outside quarter and button lap against a suitable support where it may be spread and arranged even preparatory to the marking operation.

A still further object of the invention is to provide a holding device which allows the knee and feet to operate the mechanism while the hands of the operator may be used for smoothing and straightening the uppers and also for the marking operation.

In the accompanying drawings-Figure 1 is a top plan view of an embodiment of the invention, the uppers of a shoe being used in connection therewith; Fig. 2 is a view similar to Fig. 1 showing the uppers folded and ready for the marking operation; Fig. 3 is a front view of the structure shown in F ig; 1; Fig. t is a side view of the structure shown in Fig. 3; Fig. 5 is a fragmentary sectional View through Fig. 1 approximately on line 5 5, the same being shown on an enlarged scale; Fig. 6 is a fragmentary sectional view through Fig. Z on line 6-6, the same being on an enlarged scale.

Referring to the accompanying drawings by numerals, 1 indicates a table which may be made of any desired material, but preferably of metal cast with a pair of depending lugs 2 and 3, and with ahollow depending guide 4. The .table 1 may be secured to any desired kind of support and at any height, but preferably at the proper height for an operators knee to strike against the pressure plate 5 (Fig. 3) so that the operator may by moving his knee to one side rock the rock shaft 6 through the rod 7 which is secured to the rock shaft 6 by a suitable set screw 8. The rod 7 is bent at right angles as shown in Fig. 8 and a portion projected through a tubular enlargement 9 arranged on the projection or bracket 10 of rock shaft 6. By sliding the rod 7 back and forth through the enlargement 9 the plate 5 may be adjusted to any desired position so as to be properly engaged by the operators knee. A set screw 11 is provided for rigidly clamping plate 5 to bar 7. The rock shaft 6 is pivot-ally supported by screws 12 and 13 (Fig. 1) which extend through the lugs 2 and 3, and into suitable sockets in the rock shaft 6. The rock shaft 6 in addition to the projection or socket 10 is provided with an enlargement let having a bored out or hollow portion for a shaft 15. Shaft 15 may be clamped in any adjusted position by a suitable set screw 16 so as to properly engage the link 17 (Fig. 6) which is connected with lug 18 of a pivotally mounted catch 19. The catch 19 is provided with a lug 20 whereby notches 21 and 22 are presented which receive the end 23 of the jaw or clamping bar 24-. (Io-acting with the jaw or clamping bar 24 is a second jaw or clamping bar 25 hereinafter fully described. The catch 19 is pivotally mounted at 26, the pivotal mounting consisting of a suitable pivotal pin extending through the catch and also through a bifurcated eXtension 27 formed integral with the guide 4: and top 1. p a depending lug 28 having a suitable notch therein for receiving the end of spring 29, the opposite end of spring 29 fitting into a suitable notch in the guide a whereby the lower end of the catch 19 is given a tendency to swing away from guide 1 and the upper end given a tendency to swing in an opposite direction.

The jaws 2 1 and 25 are designed to cause the upper of a shoe to be gripped or held in a predetermined position as shown in Figs. 1, 2, 5 and When the device is in the position shown in Figs. 3 and 4t the same is in operative position so that the front end of the button lap and outside quarter may be inserted beneath projection 30 on jaw 25. Arranged on jaw 25 below projection 30 is a bar 31 secured in place The catch 19 is provided with I by screws or other suitable means, which bar is provided with an aperture for accommodating the awl 32, which awl is carried by jaw24 and passes through a suitable aperture in e. ension 30. After the quarters have been inserted between projection 30 the buttons are to be placed.

In order to make the parts operate as just described, jaw 24 is fitted on to the bar 33, which bar is provided with an enlarged upper end 34 so that jaw 24 cannot accidentallybecome disconnected f om bar 33. J aw 25 is rigidly secured to a sleeve 34 in any desired manner so asto be moved upwardly and downwardly therewith. Bar 33 is slidingly fitted into sleeve and sleeve 34' in turn slidingly fits into the ride 4. Sleeve 34 is prevented from rotating by screw or other projection 35 extending into a slot, 36 formed in the sleeve. This will allow the sleeve to freely reciprocate, but willnot allow any pivotal movement there of. If desired a spline or other suitable device could be provided between sleeve 34 and bar 33 for preventing bar 33 from rotating though ordinarily this is not necessary as the awl 32 will prevent such rotation, said'awl having a portion thereof continually in the aperture formed in extension 30. Awl 32 is held in place by asuitable set screw 37, and is positively prevented from moving upwardly when pressed against the leather of the uppers by the head of a suitable screw 38 (Fig. 6). From Fig. 6 it will be noted that the lower end of the awl is designed to extend through bar 31 and into a recess or depression 39 arranged in the table 1. Rigidly secured to the lower end of sleeve 34 is a combined operating hug and stop 40, the securing means preferably belng threads, while the lower end of bar 33 has rigidly secured thereto, as for instance by threads, a stop and operating member 41. Stop 40 has connected therewith a spring 42, while stop 41 has connected therewith a spring 43. Springs 42 and 43 are also connected with suitable hoolrs on table 1 as clearly shown in Fig. 3 so that the parts will be resiliently supportedin the position shown in Figs. 3 and 4, and will be moved back to said position when moved therefrom. Preferably the springs are continually under a slight tension even when in the position shown in Figs. 3 and 4-. Connected with the lower end of bar 33 is a rod 44, which rod is connected by a suitable clamp 45 with a. second rod 46, which second rod is hooked into or otherwise pivotally connected with av trea'dle. 47. ld henever treadle 4-7 is moved downwardly rod 44 will be moved downwardly until jaw 24 en ages jaw 25, and then both jaws together with rod 44 and sleeve 34- will move downwardly until the parts assume the position shown in Fig. lVhen treadle 4-7 is released the parts will automatically rise to the position shown in Fig. 3 under the action of springs 42 and 43. In Fig. 6 it will be noticed that a buliing member of rubber or other suitable material 48 is provided for cushioning the upward movement of the respective parts.

When the uppers of a shoe are spread out as shown. in Fig. l the outside quarter and button lap may be properly arranged, and while thus arranged the awl 32 is forced through the various parts (F 5) and thereby holds the same properly in place regardless of what may be done thereafter.- lVhen attempting to hold the parts of the uppers in place by hand oftentimes the parts slip, and in fact usually the parts slip so that when a pencil or other marking tool is inserted through the buttonholes 49 the same will not promptly mark the quarters for the buttons. If the buttons are not properly placed there will be a. puckering action when the shoe is placed upon the las As the parts may be easily placed in proper position when the same are spread as shown in Fig. 1 it is evident that if held in such position while folding the various parts so as to occupy the position shown 1n Figs. 2 and 6 a proper marking may easily be had by inserting a marking tool into the various buttonholes 49.

It is to be noted that the present invention presents means which in effect allows one operator to do the work required by four hands, and with the l'l'lGCl'liIIliCtll hands the present construction rigidly holds the parts in correct position and positively prevents any slipping during the straightening of the button lap and other parts of the uppers, and also prevents any slipping or movement of the parts while the marking operation is taking place.

From Fig. 5 is will be noticed that when the treadle 47 is first depressed awl 32 will pierce certain parts of the uppers and jaw 24 will be clamped tightly against jaw 25, while jaw 25 will be pressed against lug 20, the same resting in notch21. By reason of lug 20 the parts cannot move downwardly from the position shown in Fig. 5 until the knee resting against plate 5 has been moved to one side, whereupon rock shaft 6 will be moved and catch 19 moved from beneath jaw 25, whereupon the continued downward pressure on treadle 47 will cause the jaws 24 and 25 to move from the position shown in Fig. 5, whereupon the knee of the operator will release plate 5 and catch 19 will automatically move to the position shown in Fig. 6 under the action of spring 29. After the parts are in the position shown in Fig. 6- the uppers are smoothed out as shown in Fig. 2 and then marked. When the marking operation has been completed and it is desired to remove the uppers fromthe device, the knee of the operator is moved until catch 19 is disengaged from the jaw 2 L, whereupon springs 42 and 4-3 will move the various parts to the position shown in Fig. l. The device is then in position for another operation.
