Specication of Letters Patent.

I Application filed June 3, 1916. Serial No. 101,448.

y,To all whom t may concern.'

dent of the city of NewYork, borough of Manhattan, in thecounty and State of New York, have invented a new and Improved Insole, of which the following is a full, clear, and exact description.

Myinvention is an improvement in the class of insoles which are particularly designed and adapted for use in rubber boots and comprise leather and sheet metal layers suitably secured together.

The improvement is hereinafter described in detail and illustrated in the accompanying drawing, in which:

Figure l is a plan View of the insole with part broken out; Fig. 2.is a longitudinal central section of the same on the line 2--2 of Fig. 1; and'Fig. 3 is a cross section of the same on the line 3-3 of Fig. 1.

rlhe insole in its general construction consists of a bottom layer y10 and a top layer 11, both made of leather' or a similar flexible material with a flexible sheet metal layer 12 interposed between the said layers 10 and 11. The edge of the intermediate sheet metal layer 12 terminates adistance from the edges of the bottom 'and top layers 10 and 11, andthe said layers '10 and 11 are fastened together along the margin by stitches 13 so asto securelyhold the intermediate layer i12 in position between the bottom and and waterproof cement 14 so as to prevent water or moisture from passing between the layers and to prevent an electric current from reaching the metallic intermediate layer 12. rllhe layers 10, 11 and 12 follow the contour of the inner sole of a rubber boot, and the layers are provided with upturnedflanges 15 at the instep of the foot to protectthis portion of the-foot against nails and sharp objects and to hold the foot from slipping sidewise and lengthwise. At

The edges of 'the' the instep use is made of padding pieces 16 and' 17 overlying one the Aother and interposed between the top layer 11 and the intermediate layer 12 so as to form an arch support to sustain the arch. The size of the padding 17 is slightly in excess of the' padding 16 and the margin thereof is fastened by transverse stitohes 18 to the uppermost layer 11 so as to hold the padding in place. llt will be noticed that by the arrangement described, nails or other sharp objects are prevented from passing through the insole into the Wearers foot, and the latter is held against sidewise movement and supports theJ arch thusenabling a fireman or other wearer to obtain a firm foothold on the rungs of a ladder when ascending or descending the same.

Heel and toe pads 20` and 21 are pasted orotherwise attached to the rear and front portions of the uppermost layer 11, and the said pads 20 and 21 are preferably made of felt or other soft material so as to provide a soft rest for the corresponding porratentea nee. la, raie.

tions of thewearers foot to render walking v easy and comfortable.

It is expressly understoodythat the sheet metal layer12 is made sufficiently thin to readily flex with the other layers 10 and 11.

Having thus described my invention, I claim as new and desire' to secure by Letters Patent:

An insole comprising two layers of leather, a sheet metal layer interposed between' the first named layers and "having its edges terminating short of the edges thereof whereby the margins of the same may be secured together, all of said layers having opposite laterally projecting and upturned flanges at the arch portions of the insole, superposed' padding elements arranged 'in the instep and between one of said leather layers and said metallic layer and an elec l froieras NATHANPHILLrPs.
