shoes, slippers vand similar footwear, and
the primary object of my invention is to provide a novel resilient sole -for thoroughly Ventilating and causingy a circulation of air in a shoe.
A further object of this invention is to provide a resilient inner sole for cushioning the foot, the sole being designed whereby an antiseptic or perfume can be used in connection with the same to make a shoe perfectly sanitary.
A still further objectof this invention is to provide ay simple and inexpensiye inner sole that can be easily used in connection with various styles of footwear.
With the above and other objects in view which will more readily appear -as the invention is better understood, the same consists in the novel construction, combination and arrangement of parts to be hereinafter more fully described and then specifically pointed out in the appended claims.
In the drawings: Figure 1 is a plan of an inner sole constructed in accordance with my invention, illustrating the same in an open position, Fig. 2 is an end view of the same, Fig. 3 is a cross sectional view of the inner sole as closed, Fig.' 4t is a similar view of the inner sole as closed and in condition to be placed in a shoe, and Fig. 5 is across sectional View of an inner sole illustrating a slight modification.
To put my invention into practice, I construct the inner sole of two pieces of resilient material- '1, such as light and durable rubber, these pieces of material being shaped to conform to the inner sole-shape of a shoe. The pieces of material 1 are connected by straps 2, serving functionally as hinges, whereby the pieces of material 1 can be fold# ed one upon the other, as illustrated in Figs. 3 and 4 of the drawings.
The confronting faces of the pieces'of material 1 are provided with projecting resilient prongs 3, the prongs of one piece of material being adapted to interlock or en- Specication of Letters Patent.

ter the spaces between the pronos of the adjoinin piece of material, whereby an air space wi l be provided between the pierced pieces of material 1. The pieces of material 1 are provided with perforations 1a here and there among the resilient prongs 3, these f openings or perforations allowing a circulation of air above and below the inner sole. After the pieces of material l have been' folded or placed one upon the other, I wrap the-pieces of material with a piece of fabric 4, to retain them in their folded position, and at the same time prevent therubber or esilient material from injuring a persons oot.
In Fig. 5 of the drawings, I have illustrated two pieces of material l" as bein hinged or connected together by a piece o fabric 1. In using the fabric as a hinge I dispense with the straps 2. Thev fabric used as a binding material for the pieces of material 1 is preferably of an absorbing nature, whereby the perspiration of a foot will be absorbed by the material without affecting the pieces of material 1. The projecting resilient prongs of the pieces of material 1 are adapted to allow sufficient space between said pieces of material for an antiseptic or perfume that can be readily employed to obviatethe odor set up by the perspiration of a persons foot.
I reserve the right to make the piecesof material 1 separate, and simply place one piece of material upon the other, without using thel straps 2 that serve functionally as hinges. It will thus be observed that when the inner sole is placed in a shoe, the same will serve functionally as a cushion for a persons foot, yand at the same time maintaining a circulation of air in the shoe, which -will maintain a persons foot in a perfectly sanitary condition.
I reserve the right to make such structural changes in 1n invention as are permissible by the appen ed claims.
I-Iaving now described I claim as new, is
1. An inner sole for shoes comprising two pieces of resilient material having confronting faces provided with depending prongs adapted to interlock and provide an air space between said pieces of material, a piece of fabric wound around said pieces of material to retain the same together, submy invention what stantia'lly as described.
2. An inner sole for shoes comprising two pieces of resilient material hinged together of said sole-pieces, und :i piece of fabric und adapted lo fold one upon the other, und binding Suid pieces of material together. 10 moans carried vby snid pieces of resilient nm- 1n testimony whereof I anix nly signature terial for forming un air space therebetween, in the presence of two witnesses. substantially as described.
