UNITEDSTA 1,920,170 HEEL ATTACHMENT DEVICE FOR SHOES- "Oscar Brockman, Louisville, Ky.

. Application August' 31,

2 Claims.

. structure and heel attachment device particularly adapted for use with rubber heels, such as are. commonly used for replacement purposes.

The object of the invention is to provide an improved heel and heel attachment device by means of which rubber replacement heels may be readily assembled with a shoe without the necessity for drilling the heel and withno other tools than ordinary pliers.

Further objects will appear in the course of i the following detailed description.

One sheet of drawing accompanies this specification as part thereof, in which like reference characters indicate like parts throughout.

In the drawing:

Figure 1 is a plan view of the improved attachment device;

Figure 2 is a vertical cross section through the heel part of a shoe, the improved attachment device and the improved heel in assembled relation;

Figure 3 is a view similar to Figure 2 showing a modified form. of fastening device;

Figure/l is a vertical cross section taken on line 4-'-4 of Figure 1;- e

Figure 5 is, a plan view of the improvedheel;

and

Figure 6 is a fragmentary cross section taken on line 66 of Figure 5.

Figure 7 is a fragmentary cross section taken on line 7-,-'7 of Fig. 1. p

The improved attachment device consists essentially of a U-shaped body'member 1 of sheet metal conforming'in, shape generally to that of the heel of a shoe. On the inner edge of the body part 1 is a downwardly directed flange 2 which terminates in an outwardly directed flange 3 arranged in a plane substantially parallel'with. that of the body part, but in spaced relationship thereto and forming a'slide member as-will hereinafter more clearly appear. I

On the outer edge of the body member 1 are provided a plurality of lugs '5 and '7, said lugs being preferably arranged alternately, and the lugs being bent upwardly around, an elastic bead 1931. Serial No. 560,409

member 8 which surroundsthe body 1. The alter'-- nate lugs 5 are bent upwardly, as indicated in Figure 4 and areutilized' in applying the attachment device to a shoe, in which operation the upper parts 6 of lugs 5 are bent inwardly by pliers or a similar tool over the edge of the heel part of the sole of a shoe, identified in the drawing Small lugs 11 are provided at the forward ends adapted to be turned in and engage the sole to prevent withdrawal of the device.

The improved heel differs from the usual construction by having formed on its upper face a detent 9, and further, is provided with an outwardly extending notch 10 extending around and -co-exte nsive with the wall of said detent. The notch 10 is of a thickness to receive the outwardly extending flange 3 of the attachment member in a snug sliding fit. v

A modified form of the attachment plate is illustrated in Figure 3, in which the flange parts 3 are integral with a central plate 4 co-extensive with the entire bottom or" the detent 9 in the heel and adapted to give a central support tothe heel.

Various modifications will readily suggest themselves, to those skilled in] the art, but within the scope of the invention as claimed.

Having thus described my invention, whatI claim is:

1. Aheel attachment device consisting of a substantially U-shaped plate having on its outer I edge a plurality of spaced attachment prongs adapted to be bent upwardly over and clinched to the edge of the heel part of a shoe sole, and having its inner edge bent downwardly and outwardly to form an outwardly directed flange similarly shaped, spaced from and substantially parallel with the main body part of the plate.

2. The structure of claim 1 with additional prongs intermediate the attachment prongs and a resilient bead positioned around the said plate exteriorly of the attachment prongs and secured within and by said additional intermediate prongs as specified. I

OSCAR BROCKMAN.
