RUBBER HEEL Filed July 9, 1949 INVENTOR.

Patented Apr. 10, 1951 UNITED STATES PATENT OFFICE RUBBER HEEL John H. Buechler, Chicago, Ill.

Application July 9, 1949, Serial No. 103,870

1 Claim. 1

This invention relates to improvements in a rubber heel having a removable heel plate.

The object of the invention is to provide a fastening means for removably retaining a heel plate on a soft rubber heel. The plate has countersunk holes for receiving screws forming the fastening means.

The object is obtained in the manner described in the following specification and drawings in which:

Figure 1 is a top plan view of a wire retaining member engaging a securing screw;

Figure 2 is a top view of the soft rubber heel showing the position of the cavities;

Figure 3 is a plan view showing the heel plate held in position by the screws;

Figure 4 is a section taken on the line 4-4 of Figure 2;

Figure 5 is a section taken on the line 5-5 of Figure 3 showing a screw in position;

Figure 6 is a view similar to Figure 5, showing a modification.

In Figure 1, l0 are the legs of a U-shaped wire retaining member II. The space l2 between the legs ID is of sufi'icient size to receive the tip of screw l3. The legs will engage the threads on the screw and be spread by the screw as it is rotated, thus locking the screw in place.

In Figure 2, the position of the heel plate 15 is shown in dotted lines, and 14 indicates rectangularly shaped cavities in the top surface of the soft rubber heel [1.

In Figure 3, the heel plate is shown screwed to the bottom surface of the rubber heel.

In Figure 4., I6 is a screw guiding hole in the bottom of the heel, and I4 is one of the aforementioned rectangular cavities in the top of the heel.

In operation the wire retaining members I l are inserted in cavities l4 under compression, so that upon release their natural spring will retain them in place. Next the plate is positioned on the bottom of the heel and the screws are inserted through countersunk holes in the plate, into holes I6 in the heel. The screws are then screwed into the heel cavities l4, thus passing between the legs of the wire retaining member II, which member acts as a look. It is to be noted that the screws are of less length than the thickness of the rubber heel, so as not to impair the cushioning effect of the soft rubber heel.

In the modification shown in Figure 6 the cavities M are omitted and the wire retaining members I l are embedded in the soft rubber heel.

I claim:

A rubber heel having holes formed in its wear face adapted to have screws inserted therein, and cavities formed in its upper face, the walls of each cavity retaining a U-shaped wire member in fixed position, the two legs of the said wire member being adapted to engage the threads on opposite sides of a tapered screw member for retaining a heel plate on the rubber heel, said holes being aligned with the space between the two legs of said wire member.
