PNEUMATIC SHOE SOLE Filed Nov. 29. 1926 Patented' Aug. 16, 1927.



Application ledovemberS, Q26. Serial No. 151,534.

This invention relates to pneumatic' soles for shoes, and specifically to a pneumatic sole which may be detachably secured 1n position to cover the leather outer sole and heel of a shoe, and which may easily be removed as desired.

Briefly, the invention comprehends the provisionof a pneumatic sole which may be manufactured in various widths and lengths, dependentupon the dimensions of the leather outer sole and heel to which .it

l is to be applied.' The detachable pneumatic sole is provided with a recess adapted .to e1nbracethe heel of the shoe, and with instru- A inentalities,I facilitating the operation of applying the pneumatic sole in its operative position around the leather heel and sole, and of removing it therefrom.

The primary object of the invention therefore, is the provision of a commerciali practicable pneumatic sole or cushion whic 1 may be applied to the ordinary heel andv outer sole of a shoe, and including means facilitating the attachment and detachment operative position.

'Other objects of the invention will -b e made apparent in the accompanying specification, whenv read in connection with the drawings forming a part thereof.

ln said drawings: Y

Fig. 1 is a side elevation view of a shoe, having applied thereto the pneumatic .sole forming the subject matter of my invention, the pneumatic sole being shown in' longitudinal cross-section.

Fig. 2 ris a perspective View of the pneumatic sole partly broken awayl Fig. 3 is a lateral cross section of the.

shoe and pneumatic sole on the line 3 3 of Fim 1.

Fig. 4 is an enlarged detail in section, of one of the resilient connectors in` a wire which holds'the pneumatic, sole in operative position, and,

` Fig. 5 is a perspective View Vof a 'plate which assists in retaining the pneumatic sole in position. y .y .f

Now referring specicall to the drawings, in which like reference c aracters indicate spring metal.

of said pneumatic sole intoV and from itsv like parts throughout the several views, A is an ordinary slice, equipped with the usual heel portion 1, and the customary outer leather sole 2. It is to be noted that in all heavy` walking shoes of the present day type, the outer sole of the shoe projects beyond the upper portion A, the 'latter being curved downward and 'inwardly at its )uncture with the heel and sole, to forni a groove 3, extending entirely around the shoe'. 60 Into this groove 3 is applied the device which4 assists in retaining the pneumatic sole in position, as will hereinafter appear. The pneumatic sole B is best illustrated in Fig. 2, comprising a hollow body of fieri` ible rubber, having the general contour of a shoe sole, and provided at its top edge with a bead 4, in which is positioned a wire 5 of The sole B is formed with a heel-shaped cavity 6 at the rear end, said 70 cavity` being deined by a step 7, integral ...with the flat portion 8, shaped to coincide with the bottom surface of the leather sole 2 of the shoe.

The wire 5 extends entireiy around the 75 sole B, within the bead 4, but, to permit easy attachment of the sole B to thesole 2, the wire 5 is formed in two sections 5EL and 5b, and flexible connectors C are provided on each side of said wire, said connectors being best shown in Fig. 4. The connectors C are identical, comprising an elongated me- 'tallic shell 9, one end of the shell being iiiteriorlyy screw-threaded to receive a hollow plug 10 through which section 5a of the wire S5 extendsgaa head 11 being secured to the end foft said section 5, to retain the latter in ffl/position.. The end of the section 5l of the [wire extends through an aperture in the opposite end of the shell 9, and carries a'90 head 12 which is slidable within the shell 9, and a coiled spring 13 encirclesithe section 5b and tends at al1 times to force the head 12 towards the bead 11, and to thereby decrease i the length of the area encircled by the wire 5, as will be understood. It is clear that, when the toe portion of the sole B is placed over the toe portion of the: sole-2, a reai-. ward pull on the heel portion of the sole B will cause the head A12 4to move away from 100 groove 3.

the head 11 (see liligfi) and elongate the wire 5 and' the sole B, theiierihili'v of the ing the sole B "so the'sole 2, eemprises the plaie 14 of ihm. spring; meie having ai.
