SHOE SOLE Filed Jan. 10, 1959 Inventor Patented Sept. 24, 1940 UNITED STATES PATENT @FFHCE 1 Claim.

The present invention relates to'new and useful improvements in shoe soles and has for its primary object to provide, in a manner as hereinafter set forth, an article of this character comprising a novel construction and arrangement whereby durability and comfort will be materially increased.

Other objects of the invention are to provide a shoe sole of the character described which will be comparatively simple in construction, light in weight, attractive in appearance and which may be manufactured at low cost.

All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the following specification, taken in connection with the accompanying drawing wherein like characters of reference designate corresponding parts throughout the several views, and wherein:

Figure l is a bottom plan view of a shoe provided with a sole constructed in accordance with the present invention.

Figure 2 is a longitudinal sectional view through the invention.

Figure 3 is a detail view in perspective of the Wear resisting disk.

Referring now to the drawing in detail, it will be seen that the embodiment of the invention which has been illustrated comprises a sole 1 of 30 leather having formed therein a tapered, circular opening 2. The reference numeral 3 designates a portion of the upper of theshoe to which the sole l is attached in the usual manner and 4 designates the heel of the shoe.

Threaded into the opening 2 and permanently secured therein by cementing is a tapered disk 5 of suitable flexible wear resisting material, preferably rubber or corded rubber. As illustrated to advantage in Fig. 3 of the drawing, the periphery 4,0 of the tapered disk 5 is threaded, as at 6.

It will be observed that the disk 5 is located substantially beneath the ball' of the foot when the shoe is in use where the greatest wear and flexing occur. It will thus be seen that the life of the sole will be considerably prolonged due to the greater wear resisting quality of the disk 5. Also, 5 as a result of the greater flexibility of the disk 5 as compared with the leather from which the sole I is made comfort to the wearer will be greatly increased. The taper of the circular opening 2 is from the upper or rough side to the smooth or 10 v lower side of the sole 1 and, therefore, the disk 5 is inserted from the upper or rough side before the sole is applied to the shoe. The invention may be incorporated in new shoes or in repair" soles. In the latter case the repairman may shift 15 the sole in any direction within certain limits, of course, before securing said sole to position the disk 5 as desired. In addition to increasing wear and comfort, the disk 5 is adapted to absorb considerable of the shock to which the ball of the 20 foot is subjected. Of course, the disk 5 may be of any suitable diameter.

It is believed that the many advantages of a shoe sole constructed in accordance with the present invention will be readily understood and 25 although a preferred embodiment of said sole is as illustrated and described, it is to be understood that changes in the details of construction may be resorted to which will fall within the scope of the invention as claimed.

What is claimed is:

In a shoe, a leather sole having a circular opening in the ball portion thereof, said opening tapering from the upper face of the sole through the lower face, a disk of resilient material of sub- 35 stantially the same thickness as the thickness of the sole and threaded in the opening and cemented in said opening with its upper and lower faces flush with the upper and lower faces of the sole.
