INSOLE.

Specicatlon of Letters Patent.

Patented Dec. 8, 1914.

Application led July 8, 1914. Serial No. 849,733.

To all whom it may concern:

Be it known that I, ANDREW ZSEMBA, a subject of the Hungarian Empire, and a resident of Berkeley, county of Alameda, State of California, have invented certain new and ruseful Improvements in Insoles, of which the following is a full and clear specification, reference being had to the'accompanying drawings, in which- Figure 1 is a plan view; and Fig. 2 is a transverse sectional view taken on the line 2 2 of Fig. 1.

This invention has relation to that class of insoles adapted to be removably placed in the shoe, and the object of this invention is to provide such an insole of a durable nature and which can be made thin enough to be rendered comfortable in the smallest of shoes, especially ladies shoes.

A further object is to so construct the insoles that wear on the soles of the stocking will be reduced to the utmost minimum and a still further object is to so construct the insole that moisture cannot seep up through it to the foot.

A further object is to so construct the device that it shall always lie flat in the shoe, the material and the structure of this device being such that the putting on and taking off of theshoe will not bend or buckle the sole or cause it to curl or bend around at the edges. .Y

A still further object is to construct the device of such material that heating of the foot will be avoided, so that use of my insole will tend to prevent soreness of the feet and to cure certain foot ailments, as more fully hereinafter set forth.

The device in its simplest form consists of a flexible bottom layer a of thin leather or suitable textile fabric having secured upon its upper face a sheet of imperforate material b, the fastening means consisting preferably of a line or lines of stitching c running around the edges of the sole. The material b is co-extensive with the under member of the insole and its upper surface is smooth to a glass-like degree. This material, so far as its glass-like surface and its imperviousness are concerned, is similar to isinglass and natural isinglass would be a satisfactory material, it is believed, if perfect sheets of suflcient size were possible of obtaining at a. suiciently low cost. The material I prefer is well known on the market and is sometimes called isinglass in the trade, but as a matter of fact it is of a gelatinous or celluloid nature. This material is flexible in that the sole will be permitted to bend both longitudinally and transversely, vbut it cannot curl. The result of the use of this surfacing material for the insole is that the insole may be made exceedingly thin, thus permitting it to be used in the ti ghtest shoes and especially ladies shoes. This thinness is obtained without in the least sacrificing durability, since, as a matter of fact, my insole is more durable than the ordinary insoles made of fabric or leather. My insole is further advantageous in that it forms an absolute moisture dam over the entire area of the sole of the shoe and thus prevents moisture seeping up through the sole to the foot of the wearer. The glassy upper surface of the upper material enables the shoe to be put on and taken off Without suflicient friction being caused to crumple or buckle the insole. This insole has been found to be greatly beneficial to sore feet in that it prevents overheating of the soles of the feet.

For the purpose of insuring against rumpling or buckling of the upper layer, I run one or more lines of stitching d transversel across the sole at one or more points, these ines of stitching servingito fasten the two layers, together with any intermediate padding that might be employed, togethei.

Having thus described my invention, what I claim is:

A slip insole having bottom and top surfaces which are entirelv flat and shaped to fit the interior of a shoe, comprising two layers of relatively thin material fastened together in superposed relation and lying in close contact with each other throughout their area, the bottom layer being fabric and the top layer being formed of a material that is smooth, non-heating. moisture-proof, and sufficiently flexible to be bent longitudinally or transversely to facilitate its insertion in and removal from a shoe.

' In testimony whereof I hereunto aflx my signature in the presence of two witnesses.
