ASSIGNORS TO THE GOODYEARS METALLIC RUBBER SHOE COMPANY, A CORPORA- TION OF CONNECTICUT.

SOLE FOR BOOTS AND SHOES.

Specification of Letters Patent.

Patented Dec. 11, 191 '7.

To all whom it may concern:

Be it known that we, WILLIAM B. WIE- GAND and TALMON H. Brenna, both subjects of the King of Great Britain, residing at Montreal, Province of Quebec, Dominion of Canada, have invented certain new and useful Improvements in Soles for Boots and- Shoes, of which the following is a full, clear, and exact description.

This invention relates to boots and shoes and more particularly to rubber soles for this class of articles.

An object of the invention is to provide a sole which will combine lightness of weight and flexibility with maximum cushion for the bottom of the foot of the wearer. A further object is to provide a sole which will insulate the foot, that is, will prevent heat or cold being conducted through the sole to the foot.

To attain these results we provide a sole embodying as a whole, or including as any component part, a layer of sponge rubber which forms a comfortable cushion and the air cells in which prevent heat or cold conduction to the wearers foot.

- The invention can be readily understood from the following description taken in connection' with the accompanying drawing; in which Figure 1 is a side elevation of a shoe embodying our improvements; m

Fig. 2' is a cross-sectional view on the line 2 -2, Fig. 1.

We willdescribe one embodiment of the invention in connection with a tennis or outing shoe'although the sole may be equally well applied to other types of shoes and to boots. In the drawing 10 designates the upper, 11 the insole, and 12 the filler of a tennis shoe, these parts. being of the usual and well known construction.

In the present embodiment of the invention we provide a sole comprising a tread 13 formed of rubber and a backin I14 therefor formed of sponge rubber. he tread is formed of rubber compound having a maximum flexibility and wear resisting qualities and is relatively thin so that it will be light in weight as well asstrong and flexible. The sponge rubber backing is relatively thick and consequently forms a comfortable cushion for the foot of the wearer. The air cells of the sponge rubber form insulators which upon the upper in the usual manner.

prevent heat and cold conduction through the backing to the wearers foot from decks, pavements, etc.

To produce a water tight joint between the sole and the upper as well as to confine and protect the edges of the backing from abrasive wear, the tread is turned upwardly at the sides as shown at 15, to extend above the backing, and is then continued upwardly to form a foxing 16 which extends upwardly The lateral portions extending upwardly from the tread form a single vulcanized bond along the edges of the backing thus providing a strong wear-resisting construction.

In, constructing the article the raw tread and backing may be first'assembled, a layer of rubber treated fabric 17 being inserted between the bottom face of the backing and the top face of the tread, to promote better union of the parts during vulcanization. The assembled tread and backing may then be applied to the previously assembled upper, insole, and filler. A layer of'rubber treated fabric 18 is inserted between the top face ofthe backing and the inturned edges of the upper and the filler to promote firm union between the parts during vulcanization. The foxing strip is as usual cemented or otherwise secured to the upper. To complete the article it is put in a vulcan'izer and vulcanized, the various rubber parts fiowing together and becoming integral and unitary during vulcanization.

We do not restrict ourselves to the above described sequence of operations in assembling the various parts of the article as we may resort to any desired sequence in assembling the component parts of the article without sacrificing any of the advantages of the invention.

Furthermore we may resort to various modifications in the construction of the sole, even dispensin with the rubber tread if desired, or substituting therefor a leather or other tread. We may furthermore dispense with either or both of the. rubber treated fabric layers 1718 if desired since these are not essential.

We may also dispense with the upturned edges of the outsole if desired and substitute independent confining means at the edges of the sponge'rubber cushion, it being simply preferable that some means be provided, when the cushion is of great thickness, -to confine the same against spreading outwardly under load, and to prevent injury to the same.

As many apparently widely different embodiments of this invention could be-made Without departing from the spirit thereof, it is to be understood thatwe do not intend to limit outselves to the specific form of the invention as set forth except as indicated in the appendedclaims.

What is claimed is:

1. A boot or shoe embodying an upper, a rubber tread having lateral portions of rubber forming part of the tread extending upwardly upon and secured to the upper, and a sponge rubber cushion between the tread and upper held in place and having its edges protected by said lateral portions, said lateral portion forming a single vulcanized bond along the edges of said cushion and the sides of said upper.

2. A rubber sole embodying a rubber tread having lateral portions of rubber forming part of the tread extending upwardly and terminating in a foxing strip, and a sponge rubber backing held in place and having its edges protected by said lateral portions, said lateral portions forming a single vulcanized bond along the edges of said backing.

Signed at Montreal, Canada, this 22 day of October, 1915.
