Patented Mar. 10, 1942 SHOE Ernest A. Bickford, Worcester, Mass., assignor to Wiley-Bickford-Sweet Corporation, Worcester, Mass., a corporation of Massachusetts Application November 28, 1939, Serial No. 306,532

1 Claim.

The present invention relates to shoes and more particularly to a shoe having a sole adhesively united to the upper.

The principal objects of this invention include the provision of a rubber outer sole having a fabric strip bonded thereto, the sole and the fabric being coextensive in area, and the fabric side `of the sole being adhesively attached to the shoe upper; the provision of a shoe having a sole, as aforesaid, in which a welt-strip is sewed about the shoe on the upper edge of the sole next to the fabric, so as to bind the fabric firmly to the sole at the edge, this structure having the eifect of preventing any possibility of raveling of the fabric, and of more closely pressing the fabric to the outsole.

Other objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying drawing, in which- Fig. 1 is a top plan View of the sole prior to securement to the upper;

Fig. 2 is a longitudinal section vof the toe end of the shoe with the outer and inner soles separated;

Fig. 3 is a longitudinal section of the toe end of the completed shoe;

Fig. 4 is a broken plan view of the toe end of the completed shoe, looking in the direction of arrow 4 in Fig. 3;

Fig. 5 is a perspective View of a section of the welt strip; and

Fig. 6 is a side elevation of the completed shoe.

The present invention is directed to that type of shoe in which the outsole is adhesively secured to the upper. To this end, the outsole may comprise a rubber or like piece I0 to which is secured, by pressure or other means, the strip of fabric I2, the latter being preferably of coarse, sized burlap, having wide-meshed, loosely woven characteristics, as shown at I4. The burlap, being pressed into the rubber when plastic, is penetrated by the rubber, and thus the fabric is held thereto adhesively and mechanically. This compound sole material may be made in strips and then cut to desired sole shape, as in Fig, 1.

The edges of the fabric I2 are then coated with a cellulose cement I6, or other convenient glue, and by this means secured to the upper I8. The upper I8 is secured to an insole 20, and extends down and under the same around its edges, as at 22, so that most of the cement I6 adheres to the upper I8, but not particularly to the insole. This has the effect of rmly securing the outsole to the upper, the cement I6 being easily taken by the coarse burlap I2 and the fabric or leather upper I 8.

The size sole used for a particular upper is selected so that it will be extended out somewhat from the edges of the upper, thus permitting the sole to be wider than the upper, to better retain the shape of the shoe. A continuous leather weltl strip 24 is then pressed in from the edges of the outsole close to the junction thereof with the upper, and is stitched, as at 26, all around the sole, The welt strip is thus held in place by the glue or cement I 6 and by the stitching 26, and the latter further binds the burlap I2 to the outsole I0, about the periphery thereof, the welt strip acting as a securing or anchoring means for the stitching and burlap. That is, if the welt strip were not present, the stitching might not include every cut end of the burlap, and in time would work loose therefrom, but the strip 24 is solid enough to both hold the stitches and include al] the burlap, no matter how roughly it has been cut. The compound sole and welt strip may be finished off on a buffer to present a smooth outward appearance.

As seen in Fig. 1 the cement I6 does not extend to the end of the heel portion, and instead, nails are driven thru the heel 28 and clinched into the insole 20. However, the cement I6 may extend all about the heel section if desired.

In order to t the junction of the upper and the outsole more closely, the welt strip 24 may be beveled, as at 3U, if desired.

A shoe made according to the present invention presents the appearance of a welt shoe,

1 while still being made by adhesion of the sole to the upper, and the welt strip and its stitching more closely press the burlap I2 to the outsole I0 and more securely bind the same together while atthe same time preventing raveling of the burlap. Also, the welt strip acts as an anchoring or holding means for the stitching, so as to retain the same against working loose from the outsole or the burlap.

Having thus described my invention and the advantages thereof, I do not wish to be limited to the details herein disclosed, otherwise than as set forth in the claim, but what I claim is:

As an article of manufacture, a shoe having an outer sole comprising a relatively heavy layer of rubber and a sheet of coarse, loosely woven fabric material pressed directly into the upper surface of said layer, said fabric being adhesively and mechanically held to the rubber and extending substantially over the entire surface thereof and to its edges, a shoe upper having an insole,

said upper extending for a short distance in under the periphery of said insole, a strip of cellulose or the like glue spread on the fabric material at the edges of the outer sole in position to contact that portion of the upper which extends under the insole, a separate leather Welt strip secured in position on the fabric material around the upper at its junction with the outer sole, said strip of glue serving to locate and hold said Welt strip as Well as the upper, said Welt extending laterally from said junction to the edge of the
