. InsoLn To all whom it may. concern.
Be it known that I, ALDEN S. BOYER, a and resident of Chicago, "in the county of Cook and State of inois, have invented a certain new and useful Improvement. in Insoles, of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawings, forminga part of t is specification. My invention relates to insoles to be worn as auxiliary linings in boots and shoes and has forits object provision of an insole suitably medicated to relieve excessive perspiration of the feet and to toughen the same.
Broadly, the distinctive feature of my invention lies in the fact that a medicinal agent is applied to an insole of felt or other suitable material. The medicinal agent,
which, when it comes in contact with the perspiration, sets free nascent'oxygenwhich deodorizer. s I sometimes find it desirable to cut the edges of an insole of this kind to make it fit a shoe smaller in size than the size shoe for which the insole was originally intended.
portion thereof; and Fig. 3 is a To facilitate the cutting I provide lines upon the insole of my invention to indicate the various sizes. The lines may or may not be marked to show what size is had by cutting along 'a certain line." I have not thought it necessary to mark the lines on the, drawing accompanying this application.
My. invention will be more clearly understood by referring to the accompanying invention} Fig; 2 is an enlarged section of a cross-sectional view of a portion of a modified form of insole.
In preparing my insole I prefer to usewhite felt, although it is obvious that other materials might be substituted for the felt without departing from the spirit of my invention I prefer to treat the felt insole in- (heated at A in 1, with a mixture of zinc peroxid and perhorate of soda. E ther ofthese chemicals may be used alone with good results.

Figs. 2 and 3. After the insole has been treated with the medicinal agent, I prefer to apply a mixture-of glue and shellac to one side of the insole. The glue and shellac serve to stiffen the insole, to cement the same e-shoe, and to retain the zinc peroxid, or the mixture of these two, in the interstices of thefelt. I sometimes add the glue and shellac to the zinc per-oxid, perborate of soda, or the mixture of thiese two before they are applied to the in so e.
As is well known, the perspiration of the human body contains a considerable proportion of uric acid. When the uric acid of the perspiration comes into contact with the zinc peroxid, it reacts with the same to form oxid of zinc and to set free nascent oxygen. As I have said before, the nascent oxygen acts as a deodorizer.- he Zinc oxid which remains is a healing agent which is very beneficial in cases where the'feet are afllicted with corns, bunions, chafing or the like. In a like manner the perborate of soda reacts with the uric to set free oxygen and form borax. In Fig. 3 I have shown a section of a portion of an insole provided with a backing C of suitable stifi ening material, such as hair cloth or the like; I find, however, that this backing is not absolutely neces sary as the mixture filling theinterstices of the material together with the glue and shellac serve to impart the necessary'stiffmess to the same. At D in Fig. l I have v shown lines to facilitate cutting a smaller size insole from an insole of larger size.
It is difficult if notimpdssible to give the J actual chemical reactions which take place when the acids of the perspiration come into contact with the zincperoxid or sodium perborate with which thefinsole is treated. One thing is certain, however, in either case nascent oxygen is released, and in the\case oxid is left as .a result of the reaction'or reactions which occur.
.:What I claim and desire to secure by Letters Patent is: f 1 .1. insole comprising a piece of suitshellac filling the interstices 4. An insole of suitable material imprege of felt,
:2. An insole comprising a piece of the nated with a medicinal agent adapted to' react with the uric acid of the perspiration to set free. a deodorizing agent.
5. An insole of suitable material impregnated with a medicinal agent adapted to react with the uric acid of the perspiration to form a healing agent and to set free a deodorizing agent.
6. Aninsole of suitable material impregnated with a medicinal agent adapted to react with the perspiration to set free oxygen. v 7. An insole comprising a agent adapted to react with the perspiration to form a healing agent. a
In witness whereof, I hereunto subscribe my name this 5th day of June, A. D., 1912.
