Patented Dec. 19, -1939 UNITED STATES PATENT ori-lcs 1 Claim.

My invention relates to a footwear sole and the objects of my invention are:

First, to provide a footwear sole that can be worn on a floor or surface that is wet without the 5 feet becoming wet; t

Second, to provide a sole for footwear of this applicable in connection with both the sole and` heel portion of the footwear;

Fifth, to provide a sole ofthis class which may be readily applied to footwear now in use if desired;

SiXth, to provide a footwear sole of this class which can be readily replaced; and

Seventh, to provide a footwear sole of this lclass which is very simple and economical to make, easy to place on footwearalrea'dy in use, or in the new manufacture of footwear, very efficient in its action, and which will not readily deteriorate or get out of order.

With these and other objects in view as will appear hereinafter, my invention consists of certain novel featuresof construction, combination, and arrangement of parts and portions as will be hereinafter described in detail and particularly 4 is a longitudinal sectional view of the foot portion of the sole taken from the line 4-4 of Fig.

1; and Fig. 5 is an enlarged sectional view taken from the line 5 5 of Fig. 1.

Similar characters of reference referto similar parts' and portions throughout the several views of the drawing.

My footwear sole includes a base member l which may be made of leather or relatively hard. rubber of approximately 1/4 inch thick and made o to fit the sole of the footwear upon which it is slightly smaller as shown in the drawing. There 1 is also provided a heel base portion-2 which is made of similar material and adapted to lit the heel of the shoe or may be slightly smaller if desired. The base member I is provided with groove Ia extending longitudinally along the middle thereof shown best in Fig. 2 of the drawing and in this groove is mounted a resilient tube member 3 Which has a central longitudinal hole 3a therein. It is also provided with a plurality of holes 3b eX- tending from the outside to the hole 3a, of proper size to receive nailhead for securing the sole in position the nails being designated ll shown best in Fig. 5 of the drawing and provided with heads da. This base member I is also provided with a groove ib which extends around near the margin of the base I and in which is mounted another tubular member 5 whichxis of the same construction as the tubular member 3 preferably made of rubber, soft enough to ,provide a cushion on the sole and also yieldable enough to provide means for preventing slipping on a wet hard surface. It will be noted,'however, that the rubber tubing is corrugated on its outer surface which provides additional traction to prevent slipping. Positioned in the heel base 2 is a central groove 2a in which is mounted the same kind of rrubber tubing secured in the same manner which is designated 6 and in said member 2 is a horseshoe shaped groove 2b, near the margin of the heel base portion inA which is mounted a similar tubular member designated 1. members are mounted in these grooves secured by the nails 4, the nail head being driven down through the openings 3b do-wn through the longitudinal opening 3a and against the under side,

the nail being driven through the material at the lower side and in' through the main sole portion of the footwear where it is bent as shown best in Figs. Sand 4 of the drawing. l

It will be noted that with this construction of footwear sole there is provided a rubber tubular sole portion with open spaces therein for raising' the-mainfsole `aqbov'e the floor surface that the tubular portion will flatten slightly under weight and with the corrugated surfaces provide a nonslipping footwear sole, that the tubular rubber members also provide'a cushionso that the feet do not tire and are kept dry evenwhen standing or walking on surfaces that have water standing thereon.

Though I have shown and described a particular construction, combination, and arrangement of parts and portions I do not wish to be limitedto this particular construction, combination, and arrangement but desire to include in the scope of my invention the construction, combination, and arrangement substantially as set forth in the appended claim. f

All of these tubular Having thus described my invention what I claim as new and desire to secure by Letters Patent is:

In a footwear sole, a base member of relatively 5 hard surface provided with substantially semi-circular grooves in its outer surface, hollow tubular resilient members partially embedded in said grooves and extended therefrom, said tubular
