This application is a continuation in part of application Serial No. 264,191, filed March 25, 1939. i

The present invention relates to a gauge for pulling over'machines in the art of making shoes, by means of which gauge the correct length, true center, and horizontal toe cap edge of both open and closed toe caps may be determined quickly and easily, thus. avoiding off-center and varied length toe caps and tops, as results frequently in the absence of the gauge of the present invention. I

Objects of this inventioninclude the provision of an adjustable gauge means by'which the edge of the shoe toe cap can be brought to theright point on the pulling over machine, so that it will appear in correct position on the shoe; the

provision of gauge means for correctly centering open or closed toe shoes, and of mens, womens, or boys shoes; the provision of means whereby a series of shoes of-like style can be pulled over and will be all alike with respect to the position automatically spring back out of the'way of the operative parts of the pulling over machine.

Other objects and advantages of the invention will appear hereinafter. I e

Reference is to be had to the accompanying drawings, in which I Fig. 1 is a side view of a last and shoe upper in place in a pulling over machine equipped with the novel gauge; a a

Fig. 2 is a front view of the parts shown in Fig 1; v

Fig. 3 is an elevation of the gauge forming the present invention, with a dotted'line showing of the gauge in operative position; Figs. 4a; 4b, 4c, 4d, 4e, 4 49, 4h and 4i are detail views of the parts of the gaugeshownin Fi 3. Fig. 5 is a partial elevation of a modification of the gauge bar; and Fig. 6 shows the modified gauge bar in Ioper ative position on a closed toe cap. a

The present invention is to be, applied to'a conventional and Well known. pulling over machine, such as the Rex, for example. In this machine, the correct placing of a toe tip or cap is a mere matter of the 'operators guess, and since the human eye is not infallible, it often happens that the last and shoe upper is not placed correctly as to longitudinal, lateral, and angular position with respect to the tacking elements of the machine.

The gauge which comprises the subject matter of the present invention eliminates all guesswork on the part of the operator and indicates the right point of location of the upper for the pulling over operation.

The pulling over machine is of course. well known in the art, and as it is of somewhat complex nature, it is thought not to be necessary to disclose such a machine in detail. However, in Figs. 1 and 2, there are disclosed the heel rest H3, reciprocating crank arm I2 therefor, the toe pincher It, and right and left side pinchers I6 and I8 respectively. As is well known in the art, the toe and side-pinchers grasp the toe and sides of the upper 20 and position the same in the machine. When the upper is positioned as correctly as possible by suitable manipulation of the pinchers, the pull over is accomplished by the pinchers by a well known mechanism which draws the toe 22 down behind the last 24, and the sides in behind the last, so that the-tacks may be inserted to hold the toe and sides to the bottom of the last. The front tacker arm 26 accommodates the tack-guide 28 through which the tacks are fed to the toe, and the driver 30 drives the toe tack home. Similar tack guides and drivers are provided for the sides, but are I not shown, as they are similar to the toe tacking means. Of course, it is to be understood that the front tacker arm 26, tack guide 28, and driver 30 are all mounted together, and come down behind the toe so that the toe tack may be inserted at about point 32, between the legs of the depending presser foot 3 At the same time, the heel rest l0 and rubber ,toe' bumper 36 engage and firmly hold the upper and last, and all these actions and movements are controlled by appropriate cams and cranks acting in concert, as iswell known in the art.

Now, although the conventional pulling over machine does its job as well as can be expected, the position of the upper 2|) with relation to the tack drivers depends on the accuracy of eye of the operator. Thus, an inexperienced hand will have no idea of where the exact center of the toe should be positioned, either laterally or longitudinally in the machine, and evenan experienced operator must depend on guess to get the upper in correct position. The pulling over gauge which is to be described obviates all guess-work, and thus uniformly tacked and centered uppers on single machines will result, and every pulling over operator in a shop will be enabled to center his lasts and uppers the same as the other operators. Naturally this makes all the shoes of one size exact mates, as the toe caps and tips will all be located correctly on the lasts.

The gauge itself is attached to the front end surface of the front tacker arm 26, and is provided with a flat base 40 adapted to squarely rest on the horizontal base 42 of the toe bumper 36. The base 40 is provided with a slot 44 through which and into the driving arm extends the connection bolt 46, the slot allowing the base 46 to be positioned to rest on the base 42 as desired. The base 40 is formed with spaced bearings 48 extending slightly forwardly thereof, and through which passes a pintle shaft 50. The shaft 50 mounts the inwardly extending bearings 52 connected to a plate 54, by which means the latter is pivoted to the base 40. A coil spring 56 surrounds the shaft i] between bearings 52, and one end of the spring extends through a slot in base 40 and bears against the rear surface of the base, while the other end extends through slot 60 and bears against the front surface of plate 54, thus, normally, holding the plate 56 in flat contact with its base 40, as shown in full lines in Figs. 2 and 3. It will be clear that this position of the gauge is out of the way of any and all parts of the pulling over machine at all times, and does not interfere in any way with the same. Note that the bearings 48, 52 are above the toe engaging surface of the toe bumper 36.

Plate 54 is provided with a narrowed portion having side flanges 62 to guide a slotted bar 64 therebetween; the bar 64 is adjustably secured to the plate 54 by thumb-screw 66. One end of bar 64 is provided with a lateral recess 68 which forms a guide for the gauge bar 1E1 having a gauge point 12. The gauge bar H1 is adjustably secured to the bar 64 by means of a screw entering the tapped hole 14 through the slot 16 in the gauge bar 10.

In the modification of the gauge bar 70, as shown in Fig. 5, the gauge point 18 is located between two spaced projections 80 which lie in the plane of the gauge bar and are alined with the gauge point.

Referring now to Figs. 1 and 2, the operator places the last 32 and attached upper 20, in the heel rest 10, by the heel of the last, and inserts the free side edges and toe of the upper in the respective pinchers. Then, with his finger, the operator flips the plate 54 down to dotted line position, as shown in Figs. 1, 2, 3, and as the gauge has been pre-set for the style shoe to be pulled over, the point l2 indicates where the center 82 should lie. If, as usually happens, the upper is not correctly located, the operator moves the pinchers (by well known means) until the course this is not done until the shoe is substantially completely lasted.

The shoe illustrated in Fig. 6 is a closed cap mens shoe, but it is pulled over exactly like the shoe of Figs. 1 and 2. In the case of the shoe of Fig. 6, however, the projections 80 show the operator whether the cap edge 88 is horizontal. Suppose the gauge falls where shown in Fig. 6, the operator would manipulate the pinchers to bring the cap edge of the upper into alinernent with the gauge. If pulled over when in the illustrated position, the cap would be slightly too long, and would result in mis-matched shoes, and also probably in insufficient material at the toe to hold the sole at that point. If a difierent size or style shoe is to be pulled over, the gauge may be adjusted as to length by the thumb-screw 66, but of course the center point or all shoe toes is the same, so that the length is the only variable.

By the use of the gauge as here described, inexperienced operators are enabled to turn out well pulled over uppers without trouble; there are practically no rejects, as strained uppers, broken Vamps, and torn box toes, caused by lasters efforts to compensate for off center tips, are avoided, and the bedlaster has no difficulty with the perfectly centered uppers, and can handle several more cases of shoes per day. The gauge is simple and inexpensive to manufacture, does not get out of condition, and always perfectly performs its operation. It can be adjusted 101 any type of shoe, and once so adjusted, needs no intermediate adjustments or handling of any kind except the flipping down to operative position.

Having thus described my invention and the advantages thereof, I do not wish to be limited to the details herein disclosed, otherwise than as set forth in the claims, but what I claim is:
