OSCAR MUSSINAN, OF vNEIN YORK, N. Y.

4 CUSHION PNEUMATIC HEEL.

naamw To all whom t may concern.'

Be it known that I, OSCAR MUssINAN, a cltizen of the United States, and a resident of the borough of Manhattan, in the city 5 and State of .tain new and useful ion -Pneumatic Heels, ing` is a specification.

he invention relates to cushion heels, M) and has for one of itsV principal objects to provide such a heel which and durable, which shall beeconomical of material, and which shall takeup a portion of the shock consequent upon the tread of the wearer.

The invention consists inthe novel construction, arrangement and combination of various elements and parts, as shown in the accompanying drawings and hereinafter 2o more particularly described.

In the said drawings, Figure l is a plan view of the upper face heel; Fig. 2 is a side view 3 is a section taken on the line 3-3 of Fig. l; Fig. 4 is an endvinw; Fig. 5 is a plan view of the lower fac?, Fig'. 6 is a section taken on the line 6-6 of Fig. 5; Fig. 7 `is a section taken on the line 7 7 of Fig. 5; and Figs. 8 and 9 are plan views of the proveniente in Cushof which the followof the same; Fig.

` lower and upper faces respectively, showing a modification which may be incorporated in my invention.

In carrying" my invention into effect in the embodiment thereof which I have sel lected for illustration in Figs. l to 7 incluin this specification, Il

sive and description provide a heel formed of rubber or other iiexible material provided with surface of the heel of a shoe or boot to which it may be attached. Suitable perforations 13 may be provided, through which may extend nails by means of which the eel may be secured to the shoe or boot.

In the central portion ofthe lower face of the heel I provide an arched cavity 14. The shape of this cavity 14 may be best observed in Figs. 3 to 7 inclusive, where it will be seen that it is open at the front of the heel, as shown at 15, but that on all other sides its walls curve downward and join the inner edge of the tread 11. At thecenter of the cavity 14 a secondary dome-shaped cavity 16 extends toward the upper face of the heel.

Specification of Letters Patent.

New York, have invented cer- In the modification -9 I provide a heel having a tread portion 21,

vals by arched cavities or grooves 17 which extend outward therethrough froift'he Acavity 14 to the outer air.

On the upper face of the heel I provide a cavity 18 within the portion 12. In the center of this cavity and opposite the depression 16 in the cavity 14 dome-shaped elevation 20 which may ex tend slightly above the level of the portion l hef portion 12 is broken atl intervals by means of depressions or grooves 19, oo nbe observed by an inspection of Fig. 2 that t e depressions`19 are staggered with relation to the depressions 17, and also that they are considerably smaller than the said depressions 17. I have designated the material between the upper and lower cavities 25.

shown in Figs. 8 and cavity 14, and Aprovided with laterally eX- tending cavities or grooves 23. The heel may be provided with perforations 24, anal* ogous to the perforations 13.

The upper face of the heel is provided with a peripheral portion 26, analogous to the portion 12, surrounding a depressionl 27,

grooves 29. This modification differs from that first described in that the outer ends of the depressions or grooves 23 and 29 are closed by thin portions ofl material 30. These closures are for appearance, and do not in any way aii'ect the operation of my invention. It is preferable, however, not to hermetically close the chamber formed by the depression 27 when the heel is in place. In use my cushion heel is attached in any suitable manner to the heel of a shoe or boot. When the foot is placed upon the ground in walking, the weight of the body falls upon the tread. openings 19, (or 29), and the upward pres- 4ure is in turn transmitted to the chamber ormed byrthe depression 18, (or 27), and tends to compress this chamber against the pressure of the air therein and also against the resistance caused by the downward pressure of the heel of the shoe against the elevation 20, (or 28). My heel thus takes up the shockof walking in three ways; first, by the compression of the material of the heel itratenteu any a, iai 7.

This tends to close the self; second, by the compression of the air in the chamber 18; and third, by the bending of the portion 25. The lower portion of the heel is so formed as to produce a great amount of strength by the use of a Small amount of material, and also to prevent or Eninimize possible slipping of the wearers oot.

The advantages of my invention will thus be obvious. I do not limit myself to the exact forms described, as, it is evident that various other forms might be employed,

f a depression of arched Jform extending laterally therefrom into said tread portion, anda depression in its upper face.

3. A heel provided with `a peripheral tread portion, a depression in its lower face, a depression extending laterally therefrom through said tread portion for a portion of 'pts width only; and a depression in its upper aoe.

4. A heel provided with a peripheral tread portion, a depression in its lower face, a secondary depression therein, and a depression in its upper face.

5. A heel provided with a peripheral tread portion, a depression in its lower face, a depression inits upper face, and a lateral depression extending outwardly from said last named depression into said tread portion.

6. A heel provided with a peripheral tread portionz a depression in its lower face, a depression 1n its upper face, and a lateral depression extending outwardly from said last named depression and through said tread portion for a portion of its width only.

7. A heel provided with a peripheral tread portion, a depression in its lower face, a depression in its upper face a groove eX- tending laterally from one oi said depressions, and a central elevation in said last named depression. n

8. A heel provided with a peripheral tread portion, a depression in its lower face, a depression in its upper face, a groove eX- tending laterally from one of said depressions, and a central elevation in said last named depression, said elevation extending above the level of the peripheral portion of the upper faeefof the heel.

9. A heel provided with a peripheral tread portion,l a depression in its lower face, secondary depressions extending laterally therefrom, a depression in its upper face, and secondary depressions extendinglaterally therefrom, said upper and lower depressions being staggered with relation to each other.

l0.- A heel provided with a peripheral tread portion, a depressionin its lower face, a secondary depression therein, a depression in its upper face, anda central elevation in said last named depression.

l1. A heel provided with a peripheral tread portion, a depression in its lower face, a secondary depression therein, a depression in its upper face, and a central elevation in said last named depression, said elevation extending above the level of the peripheral portion of the upper face of the heel.

In witness whereof I have hereunto signed my name this 18th day of August, 1916.
