Application filed. February 7, 1920. Serial No. 356,815.
I To all whom it may concern:
Be it known that I, ALBERT H. AMMANN, a citizen of the United States, residing at Peotone, in the county of Will and State of Illinois, have invented new and useful Improvements in Cushion-Heels, of which the ollowing is a specification.
This lnvention relates to cushion heels consisting of a rubber block or plate which is nailed or otherwise fastened to the bottom of the shoe, and the object of the invention is to provide a heel of this kind having a greater degree of resiliency than the ordinary solid rubber heel, and which also assists the wearer when walking, as well: as
tending to correct improper walking of the of the heel; Fig. 2 is a section thereof on the line 2-2 of Fig. 1; Fig. 3 is a plan view of a heel showing a modification; Fig. 4 is a cross section on 'the line 4-4 of Fig. 3, and Fig. 5 is a cross section showing a heel simi lar to that in Fig 4 but having cavities in- .clined in an opposite direction.
Referring specifically to the drawing and more particularly to Figs. 1 and 2, 10 denotes a rubber heel of conventional contour, and having holes 11 through which are adapted to be passed nails, screws or other devices for fastening the heel in place on the boot or shoe. The heel is formed with a plurality of elongated and parallel internal cavities 12 which are obliquely positioned between the top and bottom of the heel.
These cavities are inclined at an angle of about 45 degrees to the plane of the top and bottom of the heel, and they lean or are inclined from the perpendicular in the direction of the rear of the heel.
The cavities 12 add to the elasticity of the heel and hence increase the cushioning efi'ect, and owing to the obliquity of the cavities,
the latter assist the person in walking. When the persons weight bears down on the heel and compresses the same, and the weight is then removed, the tendency of the heel to resume its normal shape is in a directlon to force the foot forward, thus assist 111%:13116 person in walking.
igs. 3 and 4 illustrate a difierent arrangement of cavities 12. Here, the cavities are inclined from the perpendicular in a direction transversely of the heel. By this arrangement the tendency to turn the heel outwardly is eliminated or reduced to a minimum, and the walk of the person is corrected, the heel being pulled inwardly. Fig. 5 shows the cavities inclined in the proper direction for a heel to be worn on the right foot for those who wear their heels ed on the outside, thus causing a correction in the walk opposite to that resulting from the inclination of the cavities as shown in Fig. 4.
The cavities are ,preferably formed by cutting a series of horizontal passages through the heel, and plugging their ends with rubber blocks properly cemented. Plugging of the passages may be dispensed with, however, without impairing the efii ciency of the heel.
While the inventionhas been illustrated and described in connection with heels, it will be apparent that the principle is readily applicable to soles as ',lwell, without departing from the spirit and scope of the invention.
1. A rubber heel comprising a body having a series of elongated and parallel internal cavities which are inclined from the perheel.
2. rubber heel comprising a body havties which are inclined from the perpendicular in a direction transversely of the heel.
In testimony whereof I afix my -signature.
