UNITED STATES LOUIS COLELLA, or nn'rnorr, MrcirreAN.

CUSHION RUBBER HEEL.

Application filed December 26, 1922. Serial No. 608,940.

To (ZZZ whom it may concern:

Be it known that I, LOUIS CoLnLLA, a subject of the King of Italy, residing at Detroit, in the county of Wayne and State of Michigan, have invented a new and useful Improvement in a Cushion Rubber Heel, of which the following is a specification.

My invention relates to a new and useful improvement in a cushion rubber heel and has for its object the provision of a rubbcr heel of this class which will be simple in structure, economical of manufacture and highly efficient in use.

Another object of the invention is the provision in a heel of this class of a reinforcing member and provided with channels for permitting the yielding of the material when under pressure.

Another object of the invention is the provision of a heel of this class of a pocket formed therein and communicating with a channel formed in the heel at the outside thereof.

Another object of the invention is the pro-- vision of a heel of the class mentioned having a pocket formed therein and a supporting member mounted in said pocket.

Other objects will appear hereinafter.

The invention consists in'the combinations and arrangements of parts hereinafter de scribed and claimed.

The invention will be best understood from a reference to the accompanying drawings which form a part of this specification and in which,

Fig. 1 is a side elevational view of the invention applied to a shoe,

Fig. 2 is a bottom plan view of the invention,

Fig. 3 is a top plan view of the invention,

Fig. 4 is a sectional view of the invention taken on substantially, line 44: of Fig. 2-, and

Fig. 5 is a sectional view taken on substantially line 5-5 of Fig. 3.

The invention is adapted for use with shoes of different styles and may beused either as whole heel or as a half heel, although in the drawing I have shown the invention designed as a half heel. The invention, in its preferred form of construction comprises a main body portion 9 provided with a flange at one edge said flange having an inwardly inclined surface 10 which terminates at the base of a reenforcing portion 11 which extends around the main body portion and the heel are a plurality of projections 16 I WlllCllSGlVQ as tread members. The heel, as shown in the drawings, is adapted for fas toning to the half heel 17 of the shoe 18. As shown in Fig. 5, the outside surface 19 is inclined inwardly slightly and when the heel is fastened to the shoe there takes place a slight flowing of the rubber so that the side is then perpendicular to the lower and upper surfaces thereof.

By forming the pocket in the heel the center thereof is reduced in thickness so that it is more resilient and yields more easily to the pressure that is exerted on the tread members, allowing the tread members to flow inwardly toward the center. As the center is pressed inwardly the member 14 is brought into engagement with the lower surface of the heel portion of the shoe and serves to resist the inward pressure of the heel, thus serving to support the outer or yielding surface of the heel. By forming the channels in the reenforcing portion the flexing of the heel and the inward movement of the center thereof is facilitated and a means of exit is provided for the air contained within the pocket when the same is flexed inwardly. By forming the upper edge of the sides with the surface 10, the use of glue is eliminated as the sharp edge always maintains a close connection with the surface of the material to which the rubber heel is fastened. The tread members give a thicker wearing surface to the heel. The reenforcing member also receives the fastening means so that the nails or screws or the like which are used to fasten the heel to the shoe pass through a greater thickness of material than would be the case did they not pass through this reenforcing portion.

I have thus provided a heel which gives a cushion effect to the heel and which utilizes the air within the heel as a cushion, while at the same time the structure is such that a tight connection is always maintained between the shoe and the upper edge of the heel thus effectually imprisoning the air within the pocket and the channels formedin the heel.

While I have illustrated and described the preferred form of structure I do not Wish to limit myself to the precise form of structure shown but desire to avail myself of such variations and modifications as come within the scope of the appended claims.

Having thus described my invention What I claim as new and desire to secure by Let tors Patent is:

1. A rubber heel comprising a main body portion having the upper surface there-of inclined inwardly; a reenforcing portion mounted on said body portion, at the base of said inclined portion and terminating below the upper su of said inclined portion, said reenforeing portion having a plurality of channels formed therein and in conn'nunication with a pocket formed in said main body portion, for permitting; escape of air from said pocket through said channels upon the flexing of said main body portion.

2. A rubber heel comprising a main body portion having the upper surface thereof inclined inwardly; a reinforcing portion mounted on said body portion at the base of said inclined portion and terminating below the upper surface of said inclined portion, said reenforcing portion having a plurality of channels formed in the upper surface thereof, on all sides, and coinnninicating with a pocket formed in said main body portion for permitting the flow of air from said pocket through said chan nels upon the flexing of said main body portion and conducting said air evenly over the heel to all sides.

In testimony whereof I have signed the foregoing; specification at Detroit, in the county of ayne and State of hilichigan.
