CUSHION-HEEL.

Application filed April 29. 1918.

To all whom it may concern Be it known that, I, EDWIN l). Humour,-

a. citizen of the United States. residing at Baltimore, in the State of Maryland, have invented new and useful lmprovemeuts in (.ushion-I'leels, of which the following is a specification. v

This invention relates to cushion heels and has for its object the provision of a heel which flat upon the central portion of its top and bottom whereby a flat bearing surface is always maintained and which has its top and bottom faces provided with upwardly inclined port-ions forming a saucer edge whereby a suction effect. is produced when the heel is applied to a shoe, and

whereby gaping ot' the edges from the shoe will be prevented.

An important object is the provision of a heel of this character in which the securing nails are disposed at the edges of the central flat portion whereby ample space will be provided between the securing members and the edges of the heel to permit trimming into a wide variety of sizes without impairing the advantageous construction of the flat portion having saucer edges.

Another 0l')]GCt is the provision of a heel i of this form which will be of absolutely uniform thickness throughout and which has its saucer edge rolled that is: longitudinally curved, this curvature not affecting the cen-' tral flat portion.

An additional and important object is the provision of a heel of this character which has the upper edge of its breast straight and lying in a horizontal plane in close contact with the shoe lifts whereby downward buckling at the breast will be positively prevented on account of the straight bearing thus provided.

With these and other objects and advantages in view, the invention consists in the detailed construction to be hereinafter more fully described and claimed and illustrated in the accompanying drawing in which Figure 1 is a side elevation of a portion of a shoe showing my heel, partly in section, applied thereto in position preliminary to securing it,

Fig. 2 is a. similar view, showing the heel fastened in place, v I

llatcntcd June 24, 1919..

Serial No. 231,454.

Fig. 5 is a longitudinal sectional view.

Fig.4; is a plan view of a slightly modified form. and r Fig. 7 is a sectional view therethrough.

Referring more particularly to the drawing the letter A designates a shoe heel to which my cushion heel B is adapted to be applied.

My heel comprises a body 10, formed of rubber or other suitable resilient material having a central portion 11 whichis absolutely flat upon its top and bottom. Both the top and bottom faces of the body 10 are provided with outwardly and upwardly i11 clined portions 12 and 13 which form asaucer edge. The inclined portion 12 is longitiulinally curved as shown and the portion 13 terminates in the breast 14: of the heel. The upper edge 15 of the breast is a straight line so thatv it will bear flatly against the shoe heel A when applied. The inclination of the portions. 12 and 13 is the same at the top and bottom surfaces of the body so that the heel is consequently of uniform thickness throughout.

llletallic washers 16 are embedded in the body 10 at the edges of the central flat portion and have central apertures alining with holes 17 in the body for receiving the nails 18 by means of which the heel is secured upon a shoe.

When the heel is applied to a shoe and secured in )lace by the nails or other suit able fastcmngs, the central flat portion 11.

' will be drawn into engagement with the shoe heel and the bottom face of my heel will be The provision of the straight upper edge 15 of the breast gives a flat bearing for the heel which prevents creeping and which renders any downward buckling of the breast impossible. The provision of the central flat portion 11 is very important for the reason that a flat surface bearing upon the ground is insured even though the nails might, become loose so as to allow the heel to draw away from the shoe.

A heel constructed as shown in Figs. 1 to 5 has a greater or less suction when applied, but in order to increase the suction effect I have modified the structure as shown in Figs. 6 and 7. In this form, I have shown the flat. portion 21 as provided with a cirrounded by a groove or channel 23, \Vhen this form is applied to a shoe the cup 22 will be flattened outand will have a suction efi'ect assisting in maintaining the heel in position.

From the foregoing description and a study of the drawing it will be apparent that I have thus provided a cushion heel which has all the advantages of the concave and flat types combined in a single structure, which will fit snugly against a shoe heel without gaping or buckling at the edges, and which will always present a flat surface to the ground even though the securing means mightbecoine loosened.

WVhile I have shown and described the in clined portion 12 as curved longitudinally, it will be readily understood that I reserve the right to form the inclined portions as having their upper edges all lying in the same horizontal plane.

Having thus described my invention I; claim:

1. A cushion heel comprising a body having a fiat central ortion and a peripherally extending upwardly and outwardly inclined portion constituting a saucer edge, said saucer edge being curved lon itudinallv and having its forward upper edge straight.

2. A cushion heel comprising a body having a flat central ortion and a peripherally extending upwardly and outwardly inclined portion constituting a saucer edge, said saucer edge being curved longitudinally and having every point of its forward upper edge lying in a horizontal plane.

In testimony whereof I aflix my signature.

EDWIN D. STALFORT.
