PNEUMATIC SOLE FOR SHOES.

Specification of Letters'Patent.

Application filed. October 13, 1913. Serial No. 794,899.

To all whom it may concern:

Be it known that I, EDGAR G. KAYE, a

a specification.

.My invention relates to a pneumatic sole especially adapted for use upon athletic shoes, or adapted for arrangement upon ordinary shoes to facilitate walking, run-,

ning or jumping.

The object of'my invention is the production of a pneumatic sole in the form of an attachment, which may be readily and tions and arrangements of parts hereinafter,

described and claimed.

The invention will be best understood by reference to the accompanying drawings forming a part of this specification, and in Figure 1 is aside elevation of a shoe equipped with a pneumatic sole embodylng my invention, the latter and the sole portionof the shoe being shown in section,

Fig. 2 is a top plan view of the pneumatic sole detached, Fig. 3 is a bottom plan view thereof, Fig. 1 is a perspective view of the peripheral frame of the body ofv the pneumatic sole, a portion thereof being shown in section, Fig. 5 is a perspective view of the inner or top plate of the pneumatic sole detached, Fig. 6 is a transverse section taken on substantially line m--a of Fig. 2, and Fig. 7 is a transverse section taken on substantially line 1 of Fig. 1.

The preferred form of construction as illustrated in the drawings comprises a rigid body consisting of a'peripheral frame 1 of a form corresponding with that .of the shoe sole upon which the same is designed to be attached. At the upper side .ofthe frame 1 is provided a wall 2, countersunk in said frame and detachably secured in position by means of screws 3. The front end .of the wall or plate 2 is additionally secured by means of a reinforcing plate at,

. securely held in position, notches 6 being ,provided at said end .of said plate to accommodate the pins .or .rivetso;

.Arrangedat .the underside of the frame 1 is a flexible wall 7 having its peripheral portion secured to the frame 1 by means zof pinsor rivets 8. The wall 7 is of a flexiblej nature being formed preferably of jleather, the same being normally held in an outwardly flexed or. convex position by :means .of a flexible airbag 9 inserted in :the frame .1 between; the 'walls 2 and 7. The bag 9 is inflated through the medium 0f a tube 10 which is accessible through an {opening 11 providedin the plate 2 which 1 By detachably securing the plate 2 in posietion-in the. event of the bag 9 becoming punctured or otherwise disabled, saidplate nnay be readily and easily detached .in order ito permit of removal of said bag.

, The pneumatic sole is detachably secured to the sole of the shoeby means of a headedpin or screw 13 which projects from the shoe sole, the inner end of said-pin or screw gbeing threaded into a nut or bushing '14 arranged in the shoe sole adjacent the front end thereof' The headed outer end of the ;pin or screw 13-is adapted to releasably engage a key hole slot 15 provided in the plate 2 adjacent the toeportion of thesole. The rearward end ofthe pneumatic sole is releasably flocked to the shoe sole by means of a screw 16 which extends through the latter being threaded into the rearward portion of the frame 1, as clearly shown in Fig. 1. With this arrangement it will be seen that the pneumatic sole is detachably secured to the shoe, being adapted to be detached by simply removing the screw 16, lit being clear, that upon removal of said screw or release ofthe rearward end of the pneumatic sole, the forward end of the, 'samemay be readily released by sliding the PatentedSept. 1, 1914..

which will be permitted the sole when in use, said members 17 serving as stops in this connection.

WhileI have illustrated and described the my invention into effect, this is capable of variation and modification without departing from the spirit of the invention. I, therefore, do not wish to be limited to the precise details of construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claims. I

Having described my invention what I claim as new and desire to secure by Letters Patent is:

l. The combination with a shoe, of a pneumatic sole therefor comprising a rigid hollow body open at its under side; a flexible convex outer wall at said open side of said body; a flexlble air bag arranged within said body for normally holding said outer 'wall flexed outwardly; and means on said outer wall at opposite sides thereof for preventing lateral rolling of said sole when in use, substantially as described.

2. The combination with a shoe, of a pneumaticv sole therefor comprising a rigid 1101 low body open at its under side; a flexible convex outer wall at said open side of said body; a flexible air bag arranged within said body for normally holding said outer wall flexed outwardly; and flexible strips on said outer wall at opposite sides thereof for preventing lateral rolling of the sole when in use, substantially as described.

8. The combination with a shoe, of a pneumatic sole therefor comprising a rigid peripheral frame; a rigid inner wall having its periphery secured to one side of said frame; a flexible outer wall having its periphery secured to the other side of said frame; and

a flexible air bag arranged within said frame between said inner and outer Walls for normally holding said outer wall in outwardly flexed position, substantially as described.

4. The combination with a shoe, of a pneumatic sole therefor comprising a rigid comparatively shallow body open at its under side; a flexible convex outer wall at said open side of said body; a flexible air bag arranged within said body for normally Copies of this patent may be obtained for five cents each, by addressing Washington, D. G.

holding said outer wall flexed outwardly; means for releasably securing said sole to the sole of said shoe, said means comprising a slot and pin connection between the toe portion of said sole body and the corresponding portion of the shoe sole; and a releasable connection between the opposite end portion of said sole body and the corre- "sponding portion of the shoe sole, substantially as described. preferred form of construction for carrying 5. The combination with a shoe, of a pneumatic sole therefor comprlsing a rigld comparatively shallow body open at its under side a flexible convex outer wall at said open side of said body; a flexible air bag arranged within said body for normally holding said outer wall flexed outwardly;

means for releasably securing said sole to the sole of said shoe, said means comprising aheaded pin projecting from the shoe sole adapted to releasably engage a key hole slot provided in the toe portion of said sole body; and a screw for releasably locking the opposite end of said sole body to the shoe sole, substantially as described.

6. The combination with a shoe, of a pneumatic sole therefor comprising a rigid peripheral frame; a rigid inner wall having its periphery secured to one side of said frame; a flexible outer wall having its periphery secured to the other side of said frame; and a flexible air bag arranged within said frame between said inner and outer walls for normally holding said outer wall in outwardly flexed position, said inner wall being releasably secured in position to permit of access to said air bag, substantially as described.

7. The combination with a shoe, of a pneumatic sole therefor comprising a rigid body; a flexible convex wall secured to the under side of said body; a flexible air bag arranged for normally holding said wall flexed outwardly; means for releasably securing said sole to the sole of said shoe," said means comprising a slot-ancbpin connection between one end of said sole body and the corresponding portion of the shoe sole; and a releasable connection between the opposite end portion of said sole body and the corresponding portion of. the shoe sole, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
