New Jersey a corporation of Application November 16, 1939, Serial No. 304,750 In Great Britain February23, 1939 7 Claims.

This invention relates to apparatus for use in the manufacture of prewelt shoes and is herein illustrated as embodied in a clip for-operating simultaneously on opposite sides of a prewelted upper on a last.

It is an object of this invention to provide simple and inexpensive apparatus for use in the lasting of prewelted uppers, particularly uppers within the range of infants and childrens sizes.

With this object in view, one feature of the invention comprises a clip having arms with inturned ends which engage the upper-attaching face of the welt at opposite sides of the upper without mispl-acing the welt when said arms are arranged to extend generally heightwise of the upper and over the sole portion of the last in the upper. Said arms have operative movement toward each other to advance their inturned ends into the welt crease thereby to work the welted margins at opposite sides of the upper into lasted position, The illustrated clip comprises a. band of flat resilient material bent into the form of a U and adapted to operate by its inherent resiliency to advance its inturned end portions into the welt crease. When the clip is in operative position on a shoe, its arms are spaced outwardly away from the outer edge face of the welt, thus insuring free movement of the inturned ends of the clip into the welt crease and affording sufficient space between the arms of the clip to permit a sole to be applied conveniently to the welt while the clip holds the upper in lasted position.

It is a further object of the invention to provide a clip adapted to support opposite side portions of the Welt during the initial adhesive attachment of the sole to the welt. Accordingly, in accordance with a further feature of the invention, the inturned end portions of the illustrated clip are constructed and arranged to engage the upper-attaching face of the welt at opposite sides of the upper substantially from the welt seam outwardly to the outer edge face of the welt.

These and other features of the invention will now be described with reference to the accompanying drawing and pointed out in the appended claims.

In the drawing,

Fig. 1 is a perspective View of a clip embodying the features of the present invention.

Fig. 2 is a cross-sectional view through the shank portion of a last, a prewelt upper, and a clip mounted on the upper;

Fig. 3 is a perspective View of a prewelt upper on a last with a clip in operative position thereon; and a Fig. 4 is a cross-sectional view similar to Fi 2 showing an outsole attached to the welt. I

Referring to Fig. 1 the illustrated clip comprises a piece of relatively wide, resilient sheet metal which is bent into the general shape of a U and has fiat inturned end portions H) which are arranged approximately at right angles to opposite side portions or arms l2 and in the normal position of the clip lie in a common plane.

The edges M of the inturned ends I I] have a con-- vex curvature with respect to each other and are shaped to conform generally to the curvature at opposite sides of the shank portion of a prewelt upper. In their operative position on an upper, the opposite arms I2 of the clips are spaced from each other to an extent somewhat greater than the distance between the outer edge faces of the welt at the shank portion of the upper. The edges I4 of the inturned end portions of the clip are nearer each other, when the clip is not in use, than when the clip, is in operative position on an upper. Thus, it will be seen that the inherent resiliency of the clip will force the inturned end portions I0 into the welt crease at opposite sides of the shank and work the upper into lasted position when the clip is mounted on the upper as illustrated in Fig. 2 and will hold the welted margin in lasted position while a sole is attached to the welt.-

In using the illustrated clip in the manufacture of prewelt shoes, a prewelt upper, for ex ample the upper l6 illustrated in the drawing, is pulled over the toe portion of a last, for example, the last l8, either manually or by means of a machine such, for example, as that illustrated and described in United States Letters Patent No. 2,081,228, granted May 25, 1937, on an application of Karl Engel, While the operator (or the machine) holds the upper in pulledover position on the last, the operator spreads the arms of the clip away from each other sulficiently to enable the end portions [0 of the clip to pass over the welt and thereupon the operator locates the clip relatively to the shank portion of the upper and releases the clip to permit its end portions ID to advance into the welt crease. After the end portions of the clip have entered the welt crease the clip will continue to contract and by its inherent resiliency will work the welted margin of the upper into lasted position. In this position (Fig. 2), the inturned end portions I0 of the clip engage the upper attaching face of the welt substantially from the Welt seam outwardly to the outer edge face of the welt and support the welt in position to receive an outsole, The inturned ends themselves are supported by the last bottom or, as herein illustrated, by an insole IS on the last bottom. While the welt is thus held and supported by the clip, an outsole, for example the outsole 29 illustrated in Fig. 4, may be passed through the loop of the clip, applied to the welt and attached thereto.

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

1. A clip for use in the manufacture. of prewelt shoes having arms which have inturned ends constructed and arranged to enter the welt crease at opposite sides of a prewelt upper on its last without misplacing the welt when said. arms are arranged to extend generally heightwise of the upper and over the sole portion of the last, said inturned ends engaging the upper-attaching face of the welt, and said arms having opera tive movement toward each other to advance their inturned ends into the welt crease thereby to work the welted margin at opposite sides of the upper into lasted position.

2. A cliprfor use in the manufacture of prewelt shoes having arms which have flanges constructed and, arranged to operate locally at opposite sides of: the shank portion of a prewelt upper on its last, said flanges being arranged to engage the upper-attaching face of the welt substantially from the welt. seam outwardly to the outer edge face of the welt without misplacing the welt and being of such a length that they do not extend beyond the limitstof the shank portion of the upper, and said arms having operative movement toward each other to advance their flanges into the welt crease.

3. A clip for use in the manufacture of prewelt shoes having arms which spring toward each other and have oppositely disposedlinturned ends constructed and, arranged to. operate in the welt crease at the shank portion of a prewelt upper and to engage the upper-attaching face of the-welt substantially from the welt seam outwardly to the outeredge face of thewelt without misplacing the welt, said arms in their operative position on an upper being. spaced from each other at points. adjacent to said inturned ends to an extent somewhat greater thanthe distance between the outer edge faces of the welt at opposite sides of the shank portion of the upper. r

4. A clip for use in the manufacture of prewelt shoes having arms which spring toward each other and have oppositely disposed inturned ends constructed and arranged to operate in the welt crease at the shank portion of a prewelt upper, said arms in their operative position on an upper being spaced from each other at points adjacent to said inturned ends to an extent somewhat greater than the distance between the outer edge faces of the welt at opposite sides of the shank portion of the upper, said inturned ends being constructed and arranged to engage the upper-attaching face of the welt substantially'fromthe welt seam outwardly to the outer edge face of the welt.

5. A clip for use in the manufacture of prewelt shoes having arms which spring toward each other and have oppositely disposed inturned ends which have a convex curvature relatively to each other and are arranged to operate in the welt crease at, the shank portion of a prewelt upper, said armsin their operative position on an upper being spaced, from each other at points adjacent to said inturned ends to an extent somewhat greater than the distance between the outer edge faces of the welt at opposite sides of the shank portion of the upper, the inturned ends being spaced apart from each other when the clip is not in use to a lesser extent than when the clip is in operative position on an upper 6. A clip for use in lasting preweit uppers which in its operative position on, an upper extends generally heightwise of and away from the uppensaid clip having inturned end portions which enterthe welt crease at opposite sides of the upper and engage the upper attaching face of the welt substantially from the welt seam outwardly to the outer. edge face of the welt, the workuengagingedges of said inturned ends being shaped to, conform generally to the curvature of the edge of that'portion of. the shoe bottom on which, they operate.

7.; A clip for use in lasting prewelt shoes comprising a U-shapedband of resilient metal having its end portions inturned for a distance somewhatgreater thanthe width of a welt, the oppcsediedges of said inturned end portions being convexly rounded. and normally spaced apart an extent lessthanthe distance separating the welt seam; atoppositesidesof the shank portion of alasted prewelt. shoe.
