Patented Sept. 14, 1943 WELTING FOR BOOTS AND SHOES Gaynor OGorman. Boston, Mass, assignor to United Shoe Machinery Corporation, Flemington, N. J., a corporation of New Jersey Application December 11, 1940, Serial No. 369,625

1 Claim.

This invention relates to welting used in the manufacture of shoes and to welted shoes.

Welting hitherto used commonly consists of comparatively short strips of leather connected by cemented joints to form a long strip which is supplied in rolls of several yards ready to be mounted upon the machine which is used to sew the welting to the upper and the insole of a shoe. The dimensions of such welting are likely not to be uniform, and the joints sometimes cause trouble by giving way during the sewing of the welt.

According to the present invention there is provided a Goodyear welt shoe having a welt to which the outsole is stitched, the welt consisting essentially of plasticized, highly polymerized vinyl chloride.

Referring to the accompanying drawing,

Fig. 1 shows a roll of such welting grooved and beveled; and

Fig. 2 shows a shoe in which a portion of such welting has been incorporated. I

The plasticized, highly polymerized vinyl chloride of which the welting is made is a product put out by the B. F. Goodrich Company under the trade name of Korosea1," the composition and the manufacture of this product being set forth in United States Letters Patent, No. 1,929,453.

Koroseal is a strong, flexible, water resistant material which can be obtained in a variety of colors, the colors in the pieces being uniform throughout. This uniformity of color throughout simplifies the manufacture of shoes in which Koroseal welts are incorporated, since the edge trimming operation does not change the appearance of the edges of such welts. Koroseal can be stretched somewhat, and this facilitates sewing the welts around the toe end of a shoe. Since Koroseal can be extruded, the welting can be made in strips of uniform dimensions and of indeterminate length in which no joints are present. Moreover, since Koroseal is water-resistant, there is no liability that it may absorb moisture and swell or become somewhat soft and subject to distortion as sometimes happens during the wear of a shoe having leather welting.

In the manufacture of a shoe, the new welting is sewed to the shoe and severed as is other welting. No welt beating operation is performed upon it; but instead the welt, to which asuitable ing, as has been stated, can be obtained in varl ous colors which are uniformly distributed throughout the welting. This permits the pro- I duction of contrasting color effects when desired, and does away entirely with any necessity for coloring the edge of the welt after said edge has been trimmed.

In Fig. 2, in which a portion of a finished shoe is shown, the upper is indicated at 3, the insole at 5, the outsole at I, and the Koroseal welting at 9.

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

A Goodyear welt shoe'havlng a single welt to which the outsole is stitched and which serves to hold the outsole in place, said welt consisting essentially of plasticized, highly polymerized vinyl chloride of uniform texture and color throughout.
