INSOLE FOR BOOTS AND SHOES.

v The Schedule referred to in. these Letters Patent and making part of the same To all whom it may concern: l,

Be it -knownthat I, WILLIAM WILLIAMS, ot' the city of Rochester, in the county of Monroe and State of N ew York, have invented a certain new and useful` Improvement in Insoles for Boots and Shoes; and I do hereby declare that the following is a full and exact description of the same, reference being had to the accompanying drawings, in which- Figure l is a flat view of the insole, complete.

Figure 3, a similar view, with the parts separated.

Nature of the Invention..

This invention consists of an insole composed of felt, cloth, and paper, arranged substantially as hereinafter described.

Also, an insolc-stiifener, which allows the free 'bending of the same, while it serves to'prevent wrnkling and rupture at that point.

General Description.

a'represents the bottom layer, which'is made of thin paper, and has, on the under side, a water-prooi' coat, such as oil-paint or India-rubber preparation;

b is a piece of' pasteboard; and

c, a piece of felted hair, both cut of the form oi the sole.

fis the overlying covering oi' cloth, which forms the top of the sole.

d is the shank-piece, consisting of a strip of oiled wood or its equivalent, placed within the sole, and made of' much exibilit-y, so as 'to allow the easy bending of the sole at that point.

These parts are placed together in the folllowing' manner: inst, the bottom piece n., with the pasteboard contiguous thereto, with a i'cltcd layer placed between the pnsteboard and a cloth covering, this layer of cloth preferably encircling thc edge o1" a portion or the whole of the other parts.

The fabric of-layersthus completed is then stitched, as shown at g, by means of a sewing-machine or otherwiset An important advantage in my improved in'solc is the employment of the pasteboard b, arranged as above shown and described, ot' the form and size oi' the sole, and serving as a. st-itiener to keep the sole in shape; at the same time it ofers the greatest flexibility and ease to the foot, and presents no inequalities to the tread.

The pasteboard stiiiener is cheap, easily applied, presents a fiat surface, presents no impediment in the sewing, and combineswith the felt and cloth in producing a soft, flexible, and elastic surface to the toot. If' wet, it does not become injured, as would he the case with wood', if nse'as wstitiener, and leather 1s too expensive and lacks stiffness.'

The flexible shank-piece d, placed in th'e shank of the insole, takes the strain that comes atthat point, and, therefore, prevents rupture and tear. 1t also prevent-s the longitudinal wrinkling that would otherwise occur, especially where pastoboard is used as a stiiner. It also serves to slay or stilfen the insole in drawing -the foot out of the boot. It has a special advantage in this relation, as otherwise the greet flexibility and yieldingness ot' the solo would cause it to bend and roll up. l

ySteel springs, such asare used between the heavy soles of boots and shoes,'wonld not answer in this re lation, owing to their stilt'ness, and also to their tendency to corrosion and rust, and, furthermore, for the reason that coming so closely in contact with the feet, they would be cold and uncomfortable.

What I claim as my invention, and desire to secure by Letters Patent,.is

1. The insole, consisting of the bottoni piece a, with the pastcboard contiguous thereto, in combination with the covering f and a ielted'layer interposed between said covering and the pnsteboard, substantially as described. l

2. For the purpose oi' an insolc-stiileuer, the iiexible shank-piece d or its equivalent, applied substantially as described.

WILLIAM WILLlAliIS.
