SHOE HEEL Filed Sept.- 17, 1937 mi l j Inventor A forneys lll' arrasar son ar..

. .im artsen, nl.

Eer n Application Sepe@ The present invention relates to new and useful improvements in shoe heels, and has for its primary object to provide, in a manner as herein after set forth, a cushion heel having novel pneumatic cushioning means.

Another object of the invention is to provide a shoe heel including a permanently attached lift, and a tread member detachably 'connected to said lift in a novel manner.

Another object of the invention is to provide a shoe heel embodying a construction and arrangement which is such as to assure maximum comfort and ease when standing or walking.

All of the foregoing and still further objects and advantages of the invention will become apparent from a study of the following specification, taken in connection with the accompanying drawing wherein like characters of reference designate corresponding parts through the several views and wherein:

Figure l is a bottom plan view o! the invention with the tread member omitted.

Figure 2 is a vertical sectional view through the invention.

Figure 3 is a top plan view of the tread member.

Referring now to the drawing, numeral t designates a portion of a shoe to which a left member t is permanently attached. Embedded in the lift 6 is a metallic frame member 1 of substantially the shape shown in broken lines in Fig.

0 l. The frame member l has depending from its ears it intermediate its ends embedded in the lift E holding said tube in place.

A tread member I5 has embedded therein a metallic frame member i6 of substantially the same shape as the frame member l in the lift i.

A plurality of spaced shanks I1 extend upward- 1y from the frame member I6 in the tread II and terminate in heads I8 which are engageable inthe sockets 8. Formed on the upper side of the tread member I5 is a dome shaped extension I9 open at the top as at and having an integral neck 2l. In a vertical line with and situated below the dome I9 is a recess 22. A protuberance 23 is -Iormed on the lower side of the tread member I5.

From the above it will be seen that the invenrial No. MMWR im. 3d)

'tion comprises a pneumatic cushion heel having a detachable tread portion of novel construction and operation. When the wearer of shoes equipped with the invention, places his foot on a supporting surface the protuberance 23 contacts the surface ilrst and the weight of the wearer causes the protuberance 23 to flex and compress the air within the chamber formed by the recesses i@ ,and 2t and force it through the vent l i. The vent il is of small diameter thus the air is released slowly thereby creating a cushioning efiect. As the tread member It is detachable the same may be changed from right to left foot as it wears or may be replaced by a new one when worn out. The dome shaped extension I9 and neck ti contact and conform to the recess lil in such a marmer aato form a substantially air tight connection. I

Although I have shown and described herein a preferred embodiment of my invention it is to 2e of the parts within the spirit of the invention as 25 claimed.

'What is claimed as new is:

1. A heel comprising a lift having a recess in its lower face, a resilient tread member including a raised portion engageable in the recess and conforming in shape thereto, said tread member and the raised portion thereof having a pneumatic chamber therein, a protuberance on the lower face of the tread member for flexing same and collapsing the chamber, said lift member having a vent therein for said chamber, a tube in said Avent for holding same open, said tube including anchoring lugs embedded in said lift member, a frame embedded in saidlift member, sockets on said frame, a frame embedded in said tread member and studs on the second named frame including heads engageable in said sockets for detachably securing the lift and tread member together.

2. A heel comprising a lift having a recess in its lower face, a resilient tread member including a raised portion engageable in the recess and conforming in shape thereto, said tread member and the raised portion thereof having a pneumatic chamber therein, a vent for the chamber, a frame embedded in said lift member, sockets on said frame, a frame embedded in said tread
