1,894,678, granted on January 17, 1933 uponan application of Joseph Faussaand the rearwardly extending pivoted members also .embody features. of that prior disclosure with reference especially to their cross-sectional outline and their provision for receiving fastenings. that It is to be understood,

construction of that particular character, nor limited to upper-holding means for use on the 1 forepart of the shoe, since similar meansmay be .used, if desired, at the heel end and. shank tion of a shoe.

The novelieatures of the invention will now be more particularlydescribed by reference. to

:theaccompan'ying drawing and pointed out in the claims.

"In the drawing, i i Fig. 1 is a perspective .view illustrating how the upper-holding device provided by. this invention .maybe utilized in the lasting of the forepart of .a shoe 'ina bed-lasting machine;

Fig. '2. shows a portion of a shoein. siderelevation with the upper-holding device thereon; '1,

Fig. 3 is a and V Fig. 4 is aperspective view of thenovel upperholding device detached. i

A shoe on which the'device is to be used may have beenpreviously lasted along its shank portion and theupper fastened to the insolein that I machine of a well-known type, as illustrated in Fig. 1, the machine having toe-embracing wipers 16 that are operated in the customary manner to wipe the marginalportion of the upper around the toe inwardly over theyinsole and to press it 1 firmlydo'wn upon the insole. If the toeportion of the upper materials includes a lining and ;a

box toe stiffener, the operator may. first advance planview. of'the-shoe after lasting;

and close the wipers to wipe all the different layers of the upper materials inwardly over the insole and may thereafter, in accordance with the usual practice in lasting toes with cement, retract the wipers and trim the lining and the toe stiffener back substantially to the edgeof the insole. He will then apply cement to the margin of the upper around the toe and may at the same time apply cement to the upper materials at the rear of the toe portion substantially as far back as the ball line of the shoe. Alternatively, if cement has previously been applied at the. forepart of the shoe for lasting purposes and has hardened, he will at this time apply a solvent to soften the cement. The operator then preferably wipes the margin of the upper around the toe inwardly over the insole a second time and then retracts the wipers and applies to the shoe the novel upperholding device constructed as shown in Fig. 4.

This upper-holding device comprises an upperholding member 18 formed to extend around the toe end of the shoe bottom in engagement with i the upper over the margin of the insole and provided with rearwardly extending arms for engaging the upper along the opposite sides of the toe, and other upper- holding members 20 and 22 arranged to extendalong the sides of the shoe bottom beyond these arms for engaging the upper substantially as far rearwardly as the ball line of the shoe, the members 2!!and 22 being pivotally connected respectively at 24 and 26 to the rear ends of the arms of the member H] for swinging movements widthwise of the shoe to position them in proper relation to the shoe. The toe-holding member [8, as hereinbefore suggested, is constructed substantially as disclosed in the previously mentioned Letters Patent No. 1,894,678 and is provided with a portion 28 for engaging the upper in substantially parallel relation to the bottom face of the last and with an upstanding flange portion 30 inclined somewhat outwardly over the portion 28. The two angularly related portions 28 and 30 of the member l8 are thus arranged to be engaged by the wipers iii of the lasting machine in the manner illustrated in Fig. 1 to position the member in proper relation to the toeand to press it firmly down upon the shoe bottom... Also substantially as disclosed in the. above-mentioned Letters Patent, there are provided in the portion 28 of the member l8 holes 32 arranged to receive .tacks t driven into the shoe bottom close to the edges of the wipers, and the upstanding flange 30 is provided with offset portions 34 arranged to present recesses in alinementwith the holes 32 for the shanks of the tacks and curved upper edges to be engaged by portions of the heads of the tacks to hold the member clamped down upon the shoe bottom. It will be understood that the tacks are driven in the positions shown in Fig. 1 while the member I8 is held by the wipers in pressureapplying relation to the upper, and these tacks may, as illustrated, be driven prior to the lasting of the upper between the rear end of the toe portion and the ball line.

While the toe-holding member I8 is being applied and fastened to the shoe as above described, the members 20 and 22 are preferably in idle positions where they do not interfere in any way with the placing of the member I8 upon the toe, as shown in Fig. 1. the operator, by the use of lasting. pincers 36,

' tensions the upper betweenthe toe portion and the ball line at one side of the shoe in the manner illustrated in'Fig. 1, and while holding the upper under more or less tension by the pincers swings spending portions of the member I8.

After. the lasting of the toe the appropriate upper-holding member (as shown, the member 22) inwardly over the margin of the insole, the pincers being removed prior to the completion of the inward movement of this member. It will be evident that the member 22 thus has some wiping action on the margin of the upper as it is moved into upper-holding position. Thereafter, while holding the member 22 pressed down upon the upper with one hand, the operator drives a tack or tacks t to fasten this member in upper-holding position in the same manner as the toe-holding member l8, the members 20 and 22 in the construction shown having angularly relate-'1 portions 28' and 30' and also tack holes 32 and offsets 34 substantially like the corre- After thus lasting the shoe at one side substantially from the rear end of the lasted toe portion to the portion previously lasted with staples, the operator similarly lasts the corresponding portion at the opposite side of the shoe, applying and fastening the upper-holding member 20 in the same manner as the member 22. The operator then lasts the heel end of the shoe in any desired manner, Fig. 3 illustrating the use of tacks to hold the upper at the heel seat, and thereafter removes the shoe from the bed-lasting machine. After the cement used to fasten the forepart of the upper in lasted posi tion has substantially hardened, the upper-holding device applied as described in the lasting operation is removed from the shoe.

'It will be observed that the upper-holding members 20 and 22 in the construction shown are curved somewhat widthwise of the shoe in substantial accordance with the curvature of the edge of the portions of the shoe bottotm along which these'members extend. As illustrated the members 20 and 22 present substantially flat upper-engaging faces in the same plane as the upper-engaging face of the toe-holding member 18 for use on shoes the bottoms of which are substantially flat at the forepart. It will be understood, however, that for use on shoes the bottoms of which are difierently shaped the members 20 and 22 may be curved somewhat heightwise of the shoe'to correspond to the curvature of the shoe bottom.

The illustrated upper-holding device applied andfastened as above described maintains firm pressure on the upper over the greater portion ,of

the width of its lasting margin, not only around the toe portion of the shoe bottom but also substantially as far rearwardly as the ball line, thus insuring that the upper will be securely fastened 'to the insole by the cement all along the margin of the shoe bottom throughout substantially the entire length of the forepart and also, by the compacting pressure applied to the upper, preparing this portion of the shoe bottom in a very satisfactory manner for later manufacturing operations. It will further be evident that in lasting the forepart rearwardly to the ball line in the manner described, with the use of means to clamp the upper firmly upon the insole to hold it until the cement has set, pyroxylin cement may well be utilized to fasten the upper rearwardly to the ball line as well as around the toe, with such advantages as there may be in the use of cement of new and desire to secure by Letters Patent of the -United States is: I
