I MANUFACTURE OF FOOTWEAR Filed May 11. 1929 J Dempaey [777712710 Earle 6a secured and on the opposite side the strap 8' V is attached, having a buckle 9 adapted to co- -terminate, the strap 8' laid across the front, the buckle 9' adjusted and snapped onto its stud. I I V In applying the upper to the last the folds along the lines 11 are maintained because of the tacking at 14, but the fold along line 13 is destroyed as the vamp portion 10 is forced forward again bythe instep of thelast, there being simultaneously formed, one on each side, new folds 16. Thus the front portion ofthe upper forms the foldedfpocketaso called, of the shoe; The'upper 'is drawn down over the last until-its lower edge can be I pulled over the-bottom edge of the last and stuck to an insole lying on the last bottom. Thereafter a suitable heel piece, foxings,

binder and outsole are" attached in the usual manner and the shoe submitted to heat treatment'inorder-to vulcanize it. When this has been accomplished the tacking stitches'at 14L are removed, and the last withdrawn through the throat of the upper.

The shoe'is now complete, with its folded )ocket and quarter all in one integral piece,

its extremities being joined by the single back seam'at the rear. It'is to be noted also that by choosing to use double texture cloth, or Q similar material having both its surfaces finished, there is no need of any lining as the material itself constitutes the lining of the I s roe. And bv virtue of the design, the onepiece upper forms the vamp, folded pockets and quarter Iinteg nates all side seams in the shoe.

What we claim as our invention is:

1. A shoe of vulcanized material comprising an upper having its vamp, folded pockets and quarter in one integral piece, with its ex tremities joined together along a single vertical seam.

I 2. A shoe of vulcanized material compris- 111g an upper having 1ts vamp, folded pockets 7 joined together along a single vertical seam.

3. shoe of vulcanized material comprismg a one-piece upper whose lower edge is shaped 'and'adapted to be attached directly to the sole of the 'shoe ;'said upper being fold- ;having both its'surfaces finished, a one-piece ally, and thereby elimied midway of its sides and overlying the instep to form the folded pockets; and having its extremities joined together along a single Vertical seam.

a 4. A method of making a shoe which comprises cutting out, of rubberized material a one-piece upper in such shape that its extremities may be oined together in a single vertical seam; foldingsaid upper midway of its sides with the vamp portion pushed rearward; fastening the upper ends of said folds temporarily together; placing said upper upon'a last to force the vamp portion outward so as to form the folded pockets of the shoe and completing the manufacture of the shoe including subjecting it to vulcanlzation.

A method of producing a shoe top which in oneintegral piece; attaching its side extremities together along a single vertical seam; folding the sides midway thereof with the vamp portion pushed inward; and ati taching the front upper ends of said side folds together so that when placed on a last the said folds will be retained while the said" vamp portion is forced forward to form the foldedgpockets."

'6. A method of making a shoe which comprises cutting out of IUblJGIIZQCl material,

upper in such shape that the extremities of its sides may be oined-togetheralong aback seam while its front portion can be folded between its side portions to form folded pockets; placing the-upper on a last while so folded; and completing the manufacture of the shoe including subjecting it to vulcanization.
