TREATING or LEATHER AND THE LIKE.

Application filediFebruar-y 8, 1926. Serial No. 86,894. I

This invention relates to a method of treating leather and more particularly to the method of making welts of diflerent characteristics from a single strip of leather.

The invention contemplates the making of at least two welt pieces from a single strip of leather. One of these welt pieces may be used as a calk or weather-proof welt, and the other welt iece may be used as a sandal welt or for ot er purposes as will be apparent. The invention also contemplates the application of either the 'calk welt or the other welt or both to stitch-down shoes, and an im ortant feature .of the invention is the PIOVlSlOIl of the calk welt to stitch-down shoes.

For a complete understanding of the invention,..reference is to.be had tothe follow;- ing descri tion and to the accompanying drawings orming a part of this specification. 7

In the drawings: Fig. 1 is a perspective view of a fragment of a strip of leather treated in accordance with the present invention;

Fig. 2 is a view similar to Fig. 1 after one cutting operation has been performed;

Fig. 3 is a similar view illustrating another cutting operation F ig. 4 is a perspective view of a fragment of the calk welt;

Fig. .5, isa perspective view of the thin welt piece;

Fig. 6 is a detail sectional view showing tlfie welt pieces applied to a stitch-down s oe;

Fig. 7 is a fragmentary side view of a stitch-down shoe having a calk welt.

Figs. 8 to 15 illustrate a modification.

.Fig. 8 is a perspective view of a strip of leather.

Fig. 9 is a perspective view showing the cutting operation.

Fig. 10 is a perspective view showing the appearance of the strip after the removal of the central strip, the dotted line showing the cutting line for the next operation.

Figs. 11 and 12 show the calk weltsformed from the strip shown by Fig. 10.

Fig. 13 is a view of the central strip. removed from the piece shown by Fi 9.

Fig. 14 is a fragmentary view of one of the calk welts with a pinked rib. and

Fig. 15 is a view similar to Fig. 7 showing calk welts with the pinked rib.

Referring to the drawings in detail, the

Fig. 4.

reference character 10 designates a strip of leather that is treated in accordance with the present invention. This strip 10 is cut longitudinally along the line indicated at 11 by a suitable cutter 12, as indicated on Fig. 2. The strip is also cut longitudinally from one side to a mar inal line 13 by a suitable cutter 14, as indicatedby-Fig. 3. The cutting operations result in forming from the single strip 10 two strips 15 and 16. The strip16 may be used as a sandal welt or in stitch-down shoes, or for. other 1 to the .beadepieee 18, the. latter .isroll'ed by a press-roller and by a polishing roller. The finished calk welt piece is illustrated by In Fi s. 6' and. 7, is illustrated the appli-- cation 0' the calk welt to a stitch-down shoe. The upper 20 has an outwardly down-turned portion 20. Over this down-turned portion 20 is positioned the calk welt 15, as shown more clearly by Fig. 6, and a line of stitching 21 secures the upper and the welt to the outer-sole 19. The piece 16 may, if desired, be placed between the downwardly turned upper portion 20 and the outer sole 19, as shown.

Referring to Figs. 8 to 15 which -illus-.

form a bead similar to the bee -piece 18. It

will thus be seen that by simple cutting and rolling operations, three welt pieces of different characteristics may be formed from a single piece or strip of leather. Fig. 14 shows a calk welt having its head pinked or scalloped, making rough edges on the beaded edge, as indicated at 28, and may be applied to a stitch-down shoe as shown by Fig. 15, 'in a manner similar to the application of the welt 15 with its bead-piece 18, as shown byFig. 6.

In view of the above description, the

method, construction and utility lncident to the invention will be readily understood, and it will be appreciated that bysimple cutting and rolling operations welts of various characteristics may be formed from a single strip of leather. The calk Welt pieces thus obtained maybe applied to a stitch-down shoe as hereinbefore stated.

Having thus described the invention what is claimed and desired to be secured by Letters Patent of the United States is:

1. The method of treating a strip of leather or the like to form at least one welt piece having characteristics of a caulk Welt comprising the step of removing from one strip of a strip substantially rectangular in cross section leaving a strip having two spaced longitudinally extending marginal flanges, and the dividing of said flanged strip longitudinally to form two strips each having a marginal flange.
