INNERSOLE Filed Jan. 5, 1946 INVENTOR., jrczham L, 307431,??

wang/' Patented Oct. 19, 1948 UNITED STAT-Es This invention relates to innersoles, and has for an object to provide a simple, eicient, durable, cheap innersole which cushions the foot, reduces sweating and counteracts the formation of foot afllictions such as athletes foot.

A further object is to provide a sole in which medication can be carried by one element thereof and readily replaced, removed and reinserted at will with ease and in a few seconds time.

A still further object is to provide an innersole which is light weight, cool, and easy on the feet of the user.

Further and more specific objects, features, and advantages will more clearly appear from the specification hereinafter especially when taken in connection with the accompanying drawings which illustrate a present preferred form which the invention may assume and which form part of the specification.

Briefly. and in general terms the invention includes top and bottom layers fastened at their ends and at one side with an intermediate layer insertable therebetween along the other side.

More particularly the intermediate layer is of absorbant material which contains medication. The top and bottom layers are preferably perforated.

Still more particularly the top and bottom layers are fastened together at their ends with the intermediate layer being cut away to provide openings to surround the fastening means at the ends to anchor the intermediate layer and to prevent relative slipping thereof.

The present preferred form which the invention may assume is illustrated in the drawings of which- Fig. 1 is a bottom plan view of the innersole with portions broken;

Fig. 2 kis a longitudinal vertical section taken on the line 2-2 of Fig. 1;

Fig. 3 is a transverse vertical section taken on the line 3-3 of Fig. 1; and

Fig. 4 is an enlarged vertical longitudinal section through a portion of the innersole showing the three layers of material comprising the same.

Generally speaking the innersole of this invention comprises three layers of material, (1) an upper layer of smooth material such as leather; (2) an intermediate removable layer of absorbent material such as paper or composition, preferably medicated; (3) and a bottom layer of material such as plastic. The upper and lower layers are fastened togetherl but the intermediate layers are insertable and removable.

In the drawings the innersole is shown as comprising an upper layer I2 of iiexible material such as leather preferably provided with perforations I3. A bottom layer I 0 of a composition such as light plastic is also provided with perforations II. Perforations I3 are somewhat larger than perforations II. An intermediate medicated layer I1 is insertable between the top and bottom layers I2 and I 0 respectively. It will be noted that the top and bottom layers are fastened to each other at their respective ends by means of rivets I4 and I5. The medicated layer I1 is cut away at I9 in order to clear the rivet I5 and a similar adjustment is made in the toe to clear the rivet I4.

It will be apparent from the foregoing and from an examination of the drawings that both sides between the upper and lower layers are open and it is through these openings that the intermediate layer I'l is inserted and from which it can be easily and quickly removed when desired. The intermediate layer I1 is formed of absorbent material such as paper and is preferably treated in any suitable manner with medication to counteract such foot ailictions as perspiring, athletes foot, etc.

' layer, as desired.

While the invention has been described in detail and with respect to a present preferred form which the invention may assume, it is not to be limited to such details and form since many changes and modifications may be made in the invention without departing from the spirit and scope of the invention in its broadest aspects. Hence it is desired to cover any and all forms and modifications of the invention which may come within the language or scope of any one or more of the appended claims. It has been found that myV innersole keeps the foot dry in wet weather even though the sole of the shoe becomes moist.

What I` claim as my invention is:

l. An innersole comprising top and bottom layers, the bottom layer being of smooth perforated plastic material, the top layer being of 'soft cushioning material such as leather and provided wi'th larger perforations, said layers being both ends, said intermediate layer having cutouts formed therein to clear both of said Aend` rivets.
