Application filed August 25, 1926 Serial No. 131,448.

The present invention relates to improvements in boots and shoes and has reference more particularly to a means for absorbing heel (portion of the outer whole sole being provide with an opening through which cush ioning member projects, the heel which is attached to the bottom of the heel portion of the outer sole having a pocket formed in the upper portion thereof to receive the depending portion of said cushioning member.

A further object is to provide ashoe construction wherein the welt and the inner sole of the shoe whereby are eliminated from the inside shank portion the proper flexibility will be insured.

A still further object is to provide a shoe construct-ion wherein a shock absorbing cushioning member is attached to the bottom of the rear portion of the heel.

Another object is to provide a shoe construction which is very inexpensive, strong and durable, amount of comfort to the wearer.

. Other objects and advantages of this invention will become apparent from the following description taken in connection with the accompanying drawing. I

In the accompanying drawing forming part of this specification and-in which like numerals are employed to designate like parts yet will afford a maximum ing the rubber shank after the same has been stretched across the shank portion of the sole and cemented thereto.

Figure 4 is a perspective view of the whole outer sole forming a part of the present invention.

Figure 5 is a longitudinal sectional view through the inner whole sole, the outer whole sole and the heel showing the manner in which the cushioning member and the rubber arch are associated therewith.

Figure 6 is a bottom plan view of the heel showing the cushioning member associated therewith.

In the drawings wherein for the purpose of illustration is shown the preferred embodiment of my invention,

the numeral 1 designates generally'the whole inner sole which is preferably formed of leather. Adapted to be cemented to the bottom face of the heel portion 2 of this inner sole 1 is the rear end of the shank piece of rubber 3. A cushioning member 4. which is also formed of rubber and is molded integrally with the rear portion of the rubber shank forming strip 3 is of a suitable thickness so as to form a plug, the purposeof which will be hereinafter more fully described.

- In forming the rubber shank, the forward free end portion 5 of the strip 3 is cemented to the bottom of the sole portion 6 of the inner sole 1 at a int adjacent a place where the metatarsal )ones come in contact with the sole and when the rubber strip is thus attached, the parts are arranged as shown in Figure 2. The bottom face of the shank portion 7 of the inner whole sole 1 is coated with a water the sole are stretched outwardly, the rubber strip 3 will be simultaneously stretched. When the up er face of the intermediate porproof cement and when the ends ofthroughout the same:

Figure 1 is a bottom plan view ofthe inner sole showing the cushioning member and the adjacent ortion of the rubber shank cemented to the heel portion of the whole inner sole, tfll e forward portion of the rubber shank being tion of the ru ber strip comes in contact with the cement coated bottom face of the shank portion 7 of the inner sole 1, the strip will then assume the 1position shown more clearly in mu Figure 3, t us providin a rubber shank against the bottom face 0 the shank portion of the inner-whole sole 1. The stretched strip 3 forms a permanent active flexible support for the arch of the foot. In the shoe, this rubber strip expands and contracts as the weight of the foot is pressed against it, the same as the arch of the foot expands and con tracts, in walking, when the weight of the body is on it. The arch, therefore, is held in Figure 2 is a side view showing the whole inner sole bent back upon itself with the free forward end of the rubber shank cemented to the sole, and the cushioning carrying portion of said shank being cemented'to the heel portion of the sole. Figure 3 is a view similar to Figure 1 showits proper and natural position without any discomfort to the wearer of the shoe.

Also forming a part of the present invention is the wholeouter sole designated generally by the numeral 8 as shown more clearly in Figure 4:. The heel portion 9 of the outer sole 8 is provided with an enlarged opening 10 through which the cushioning member 4 is adapted to project when the outer sole is disposed against the bottom of the inner sole.

When the inner whole sole and the outer whole sole are arranged in this manner, the. rubber shank 3 will be interposed between the shank portions of the aforementioned soles thus )rovidin a ermanent flexible su )ort under the arch of the foot.

Both the inner and outer soles are adapted .toibe crimped and molded into the hollow of the shank of the last.

j The heel of the shoe is built up of layers of leather in the manner well known in the art. and is designated generally by the numeral 11,

w ith reference more particularly to Figure 5. The heel is cemented or otherwise fastened to the-bottom of the heel portion 9 of the whole outer sole 8 in any suitable manner. The

' uppermost layers of leather forming the heel .a pocket 12 is tom of the heel 11 at the outer rear edge portion thereof, and the inner forward edge of this rubber insert is cut away at anangle as illustrated at 14 with reference more particu- Figure 7 of the drawings. This tread 13 will reduce the shock incident to of the foot coming in contact with larly to portion the heel the ground.

I The rubber cushioning member or plug 4 will materially reduce the impact and shock caused when the heel of the shoe comes in contact with the ground and will thereby prevent any serious injury being caused to the heel of the foot as frequently occurs with the ordinary type of heel now in use.

It will thus be seen from the foregoing description that I. have provided a highly novel, yet simple shoe construction whichwill afford a maximum amount of comfortto the wearer and at the same time will be inexpensive and easily and readily assembled.

\Vhile I have shown the preferred embodiment of my invention, it is to be understood that various changes in the size, shape, and arrangement of parts may be resorted to without departing from the spirit or sacrificiilig any of the advantages of the appended e aims.

Having thus described the invention, what I claim as new and desire to secure by Letters Patent is 1. In a shoe, the combination with an inner whole sole, and an outer whole sole, of a rubber shank interposed between the shank portions of said soles, said rubber shank comprising a strip of rubber which is initially cemented at its respective ends to the heel and sole portion-of the bottom face of inner whole sole, said strip of rubber being stretched across the shank portion of the inner whole sole and cemented thereto.

. 2. In a shoe, the combination of an inner whole sole, and an outer whole sOle, the outer whole sole having an opening formed in the heel portion thereof, of a heel attached to the bottom of the heel portion of the outer whole sole, said heel having a pocket formed in the upper portion thereof, a flexible shank interposed between the shank portions of said soles, the same comprising a strip of rubber which is stretched across the shank of the inner whole sole and cemented to the bottom thereof, and a rubber cushioning plug molded to said strip, said plug extending downwardly through the opening'in the heel portion of the outer whole sole and disposed within the pocket provided therefor in the heel. Y

In; testimony whereof I aflix my signature.

HENRY H. SCHWARTZ.
