Application filcdeugust 5, 1921. Serial No. 490,072.

To all whom it may concern:

Be itknown that I, Lnonnnn l GRIFFIN, a citizen of the United States, residing at Binghamton. in the county of Brooms and State of New York, have invented certain lasts and to machines by the aid of which the illustrated method may be practiced. For the purpose of explanation the inven-l tion is herein shown and described as embodied in and practiced in the use of mechanism applied to a lasting machine of the bed type, an example of which is disclosed in United States Letters Patent No. 1,018,- 477 granted February 27 1912, on application of Matthias Brock.

An object of the invention is to position, form, shape or mold the excess portion of the margin 01 the upper, particularly at the toe, in an upstanding relation to the sole to facilitate the removal of'said excess portion in the upper trimming operation;

In accordance with this object the invention provides for engaging the opposite faces of the portion ofa lasted shoe upper which extends above the innersole rib and applying pressurethereto to cause it to be molded and set in an upstanding relation to the shoe bottom and substantially over the rib so that it may be readily engaged and trimmed oit by upper trimming instrumentalities.

Since this preparationofthe excess per tion. of the upper for trimming. must be effected after the lasting operation and prior to the trimming operation. which is next in. order it is desirable to prepare the upper for trimming in conjunction with the lasting operation. Accordingly the inven tion further provides for shaping the upper into the angle between the feather and rib ot the innersole, and, in conjunction with said shaplng, applying pressure to the opposite faces. of the portion ofthe upper extending above the rib. As shown herein the upper pressing or molding means consists in members havlng CO-OPQIELUIIQ surfaces mounted respectively on the holddown or detailed description when read in connection with the accompanying drawings and will be pointed out in the appended claims.

In the drawings, Fig. 1 is a perspective view of the holddown and wipers of a bed lasting machine equipped for practicing the method of the present invention,

Fig. 2 is a longitudinal section of the parts shown in Fig. 1, and

Fig. 3 is a transverse section on the line 3-3 of Fig. 2.

ln'the drawings, the numeral 2 indicates the last, 4 an innersole upon the last bottom. 6 the rib of the innersole, 8 the feather of the innersole, 10 the upper, and 12 the excess portion of the upper which is to be treated.

The usual wipers of a bed lasting machine are indicated at 20, 22, it being under stood, of course that the machine is provided with the usual mechanism for moving the. wipers vertically to upwipe the upper about the toe of the last and for closing the wipers to force the upper into the angle between the feather 8 and the rib 6. To

support the rib against the action of the wipersa holddown member formed as a plate or block 24: is provided which is pivot- 'ed at 26 to one end of a holddown finger top of therib as'it extends below it. This face 34 is preferably located substantially in the plane of the rib that-is, in line with the direction'ot extent of the rib upwardly from the sole bottom. As shown, said face may be inclined slightly inwardly at the toe end (Fig. 2) and outwardly at the sides of the toe (Fig. 3); To co-operate with the face 34 in treating the excess portion of the upper material. extending above the rib 6 there is provided on each of the Wipers a pressure member 36. These members are firmly secured to the wipers and have acting faces 38 contoured to correspond to the face 3 of the block 26 and so located that they press the upper firmly against the face 34 when the wipers have seated the upper into the angle between the rib 6 and the feather 8 at the completion of the lasting operation. As a result the excess of upper material, particularly the fulled or bunched portion at the toe of the shoe, is molded in a predetermined upstanding position corresponding substantially to the direction of upward extent of the rib, that is, the upper is molded in the plane of the rib extended above the rib.

The block 26 is provided with a handle 40. In case the block 26 does not move upon its pivot when brought against the rib properly to engage the rib at all points, the handle 40 may be manipulated to secure such proper engagement.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States is:

1. That improvement in methods of shaping uppers which consists in lasting the upper to a ribbed innersole, and then molding the margin of the upper extending above the rib into an upstanding flange for convenient removal in the upper trimming operation.

2. That improvement in methods of shaping uppers to their lasts which consists in conforming the margin of the upper to the feather and outer face of the rib of an innersole, and then molding the margin of the upper extending above the rib into an upstanding flange for convenient removal in the upper trimming operation.

3. That improvement in methods of shaping the uppers of boots and shoes which consists in supporting the inner face of the rib of an innersole, shaping the upper against the outer face of said rib, and molding the margin of the upper extending beyond the rib into an upstanding position to facilitate removal of said margin in the upper trimming operation.

4. That improvement in methods of shaping the uppers of boots and shoes which consists in supporting the inner face of the rib of an innersole, lasting the upper against the outer face of said rib, and molding the margin of the upper extending beyond. the rib in an upstanding position substantially perpendicular to the shoe bottom and conforming to the contour of the rib to facilitate removal of said margin in the upper trimming operation.

5. In a machine of the class described, the combination of means for laying the margin of an upper inwardly over the feather of the sole of a shoe on a last, an upper engagin device arranged to be positioned on the sole and having a face to extend above the inner sole rib about the toe end of the shoe, and means on the overlaying means arranged to engage the margin of the upper opposite to said face and to act after the overlying op eration to force the upper against said face and mold it into an upwardly extending marginal flange for convenient removal in the upper trimming operation.

6. In a machine of the class described, the combination of means for engaging the opposite faces of the margin of a lasted shoe upper which extends above the innersole rib, and means for relatively moving the upper engaging means to apply pressure to the upper and cause it to be molded and set in I an upstanding relation to the shoe bottom and substantially above the rib so that it may be conveniently removed in the upper trimming operation.
