AGOSTIIN'Q SANTACROCE, OF ELYRIL OHIO, SIG-NOR OF THIS '10 JOHN GBUMBOS AND THBEE-TENTHS TO SPYBD SADARIS, BOTH OF ELYRIA, OHIO.

BU BIBEB HEEL.

Specification of Letters Patent.

Application filed November 80, 1918. Serial No. 264,782.

" in contact with the ground after the major of the heel is opening.

part of the tread has been lifted.

Another object of the invention is to provide this resilient part with a calk to prevent the heel from slipping.

Still another object of the invention is to make the projecting portion which surrounds the calk of square formation for increasing the non-slipping action of the heel.

The invention also consists in. certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out the appended claims.

In describing my invention in detail, ref erence will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which liiigure 1 is aview of the tread face of the bee Fig. 2 is a section on line 2-2 of Fig. 1.

Fig. 3 is a top view.

In these views 1 indicates the body of the heel, which has its top face of concave form and its tread face flat. The heel is provided with the usual nail-receiving holes 2 for securing the heel to the heel of the shoe. The center part'of the heel is provided with a tapered opening 3, and the top face of the heel is provided with a pair of annulargrooves 4: which are concentric with said The inner groove 'is of greater depth than the outer groove and this inner groove leaves an annular rim 5 around the larger end of the opening 3. The tread face rovided with a concentric groove 6, which 1s located between the upper grooves 4, as shown in Fig. 2.

said calk.

several These grooves make the centerpart of theheel of greater resiliency than the rest of the heel so that,

largement 7, which projects beyond the tread surface of the heel and this enlargement surrounds the small end of the openlng. A rim 8 is formed on said enlargement around said opening and extends below the sald enlargement; A calk 9 made of any suitable material. is placed in the opening 3,-

and is prevented from passing entirely through the said opening by means of the tapered formation of said opening and calk and also by the enlarged head 10 formed on As shown in Fig. 2, the head of the calk lies below the highest point of the upper surface of the heel, so that the .calk may be pressed upwardly when the heel is in place on the shoe.

It will thus be seen that, when the heel is squarely in contact with the ground the center part of the heel will be pressed upwardly until the tread surface of this part is in the same plane as the tread surface of the major part of the heel. As the foot is raised, the center part of the heel will spring back to its normal position and, thus remain in contact with the ground after the heel has been raised off the ground. This will prevent the shoe from slipping on the sole and the front part of the heel. As, the center part springs back into normal position it will tend to dislodge dirt or snow' of my invention will be readily apparent.

I desire it to be understood thatl ma make such changes in the construction an in the combination and arrangement of the parts, provided that such changes; fall within the scope of the appended claims;

What I claim is 1. A heel of the class described havin a pair of concentric grooves in its upper face and a concentric groove in its lower face Patented Aug. 12', 1919.

the rear part of forming a central resilient portion, the lower groove being located between the upper grooves.

2. A heel of'the class described having a 5 pair of concentric grooves in its upper face and a concentric groove in 1ts lower face forming a central resihent portlon, sa1d lower groove being 1002 'ed between the upper grooves, said resilient portion having a. centrally located projection and an opemng 10 and a calk seated in said opening.

In testimony whereof I affix my signature.
