UPPER-HOLDING DEVICE V Filed July 12, 1941 Patented May 26, 1942 r UNITED STATES rarer-[or ice Charles A. Robinson, Salem, Mass., assignor to United Shoe Machinery Corporation, Flemington, N. J., a corporation of.New Jersey Application July 12, 1941, Serial No. 402,109 a 11 Claims. .(o1.12,-1o7) I -This invention'relates to devices for usein the manufacture of shoes for holding end portions of uppers in lasted position. The invention is herein illustrated by reference to the lasting of the toe ends of welt shoes, but it will be understood that under appropriate conditions it is of more general applicability.

In the lasting of the toe ends of welt shoes the marginal portion of the upper is commonly wiped inwardly against a lip formed on the insole or against a shoulder otherwise provided on the insole, and it is the usual practice for the operator to fasten the toe end of the upper in lasted position by applying a binder wire around the toe against the upstanding margin of the upper and anchoring the wire to tacks driven into the shoe at the opposite sides of the forepart of the shoe bottom. Objects of" the present invention-are primarily to provide an upper-holding .device which may be applied and fastened to the shoe more quickly and conveniently than such binder wire and which may be used repeatedly in lasting different shoes. To these and other ends, the upper-holding device herein shown comprises a flexible binder. which may be conveniently made of wire and is of suitable length to extend around the lasted margin of the toe-end portion of' the upper, and members connected respectively to the opposite ends of this binder and arranged to serve as levers fulcrumed on the shoe to force the accompanying drawingand thereafter pointed out in. the claims.

In the drawing.

Fig. 1' is aviewshowing a portion of a toelasting machine and illustrating how an upperholding device constructed inaccordance with the present-invention may be applied to alshoe;

through which the binder 2 is threaded before the binder lengthwise of the shoe. and thus to- 7 apply it tightly to the margin of the upper. More particularly. in the illustrative embodiment of the invention, these levers, which are hung on the ends of the binder, are provided with comparatively short arms having pointed ends arranged to penetrate the upper in locationsoppoarranged to engage the lip of the insole to hold levers in place and thereby to retain the binder in upper-holding position. It should bev understood however, that consistently with the-objects in view the invention in some ofits aspects'is not limited to a device having levers arranged thus to swing in planes substantially parallel to the'shoe bottom or arranged to be held in place on the shoe in the particular manner herein illustrated.

The novel features of the invention will now be more particularly described with reference to the loopsare formed. The holes are so arranged that each;lever 6 has a comparatively short arm l0 and a longer. arm 12. The short arms H! are provided with points M adapted to penetrate the marginal portion of the upper in locations oppo site the usual lip a of the insole to cause the levers to fulcrum on the shoe as they are swung inplanes substantially parallel to the shoe bottime in applying the binder 2 to the shoe. The

longer arms l2 are so formed as to provide hook portions l5 arranged to extend inwardly over the lip of the insole and curved to extendheightwise of theshoe and outwardly toward the inner face of the lip, the ends of these hook portions having points !8 adapted to penetrate the lip from its inner face to assist in holding the levers in place after the binder has been applied to the shoe.

The invention is herein illustrated by reference to its'use in lasting shoes in a power-operated toe lasting machine such as disclosed in United States Letters Patent No, 2,160,846, granted on .June 6,1939, on an application of F. C. Eastmans and A. F; Pyms. Such a machine is provided with toe-lasting wipers 2!! which in time relation to other operations performed by the machine are advanced and closed to wipe" the marginal portion of the toe end of the upper inwardly over the feather of the insole and against the lipfof the above-mentioned Letters Patent, the machine comes automatically to a stop after. the

wipers have thus wiped the upper inwardly and have been raised slightly to decrease their preswire farther inwardly against the upstanding margin of the upper, after which they are again moved downwardly and are advanced and closed to a'pply their full pressure to the upper crumed on the shoe independently of each other and to press the binder against the upper. The

machine then comes to a stop a second time to;

permit the operator to fasten the binder to the shoe and to sever it from the source of wire supply. In using an upper-holding device such as, herein shown in lasting a shoe with this machine ;cluding a binder'for engaging the upper around the end ofthe shoe, and members connected to said binder and arranged to serve as levers ful- -to forcethe binder lengthwise of the shoe while sition around an'end of a shoe, said device inthe operator, supporting the device by its levers.

6, may apply itpreliminarily about the toe with the binder 2 pulled part way in between the wipers and the upper by. bodily movements of the levers when the machine first comes to va stop as above described, and will thereafter pull the cluding a binder for engaging the upper around the end of the shoe, and members connected respectively to opposite ends of said binder and binder fully in against the upstanding margin of the upper as more readily permitted by the wipers after the machine has again been started. Before the machine again comes toa stop the wipers will press the binder against the upper in the same manner as when acting on binder wire such as used heretofore. After the machine has come to a stop the second time, the operator will positions where their hook portions I6 extend over the lip of the insoleas illustrated in Fig. 2 with their pointed ends l8 penetrating the lip at its inner side, so that the levers are held byv the shoe effectively against'displacement with the binder 2 in upper-holding position. By ref- 'The levers are thus swung by the operator to erence to Fig. 3, which shows the parts in'substantially the samerelation as in Fig. 2, it will be evident that when the device is in place on a shoe'the levers G'extend generally lengthwise of the shoe and that by reason of the relation of the holes 8 to the pointed ends ll of the levers which penetrate the upper, the portions of the binder along the sides of the toe are held close,

to the upstanding margin of the upper. I i

- It will be understood that upper-holding de-'- vicesprovided by this invention are adapted for use, in place of binder wiresuch as commonly used heretofore, in lasting shoes not only with machines such as shown in the previously mentioned Letters Patent but'with various machines.

-5. A device for holding the marginal portion of an upper in lasted position against a lip or shoulder on an insole around an end'of the iner and havingpointed ends adapted to penetrate 'the upper, said members being arranged to serve as levers'fulcrumed on the upper at their pointed ends in locations opposite the lip or shoulder of the insole to force the binder length- In lasting shoes, for example, with: well-known I bed-lastin machines having manually operated wipers, such devices will be applied to the shoes at the same time when it has been customary heretofore to apply thebinder wire, the binder 2 being pulled inwardly against the upstanding margin of the upper under the wipers by a pull applied bythe operator to the levers 6 and being then forced more firmly against the upper by swinging movements of the levers fulcrumed on theyshoe in the manner hereinabove described. It will be understood that such an upper-holding devic'e'will remain on the shoe until the upper,
