INNER SOLE.

To aZZ whom, it away cancer-n:

Be it known that I,JOHN V. ALLEN, of Weymouth, in the county of Norfolk and State of Massachusetts, have invented certain new and useful Improvements in Inner Soles, of which the following is a specification.

This invention relates to inner soles, and particularly those adapted for use in welted boots and shoes, one side of. the sole being out along its margin to form a stitch-receiving channel or channels. The channeling of the sole reduces its thickness to a consider.- able extent, leaving the sole undesirably limp and flabby at its marginal portion.

My invention has for its object to stiffen the channeled portion of the sole Without increasing its thickness; and to this end it consists in an innersole having its channeled portion provided with pins extending from the margin of the soleinwardly across the channel or channels cut therein, the pins being between the bottoms of the channels and the sents a view similar to Fig. 3, showing the sole after it has been channeled.

The same letters of reference indicate the same parts in all the figures.

In carrying out my invention I insert in the edge of an inner sole a a series of slender pins 1), which are preferably of steel or other suitable metal and are of such diameter that they can be inserted between the channels I) b and the side of the sole opposite the side from which the lips 19 formed by the channels, project. The length of the pins is such that they project across the channeled portion of the sole, and they are placed sufficiently close together to cause them to stiffen the chan-. neled portion and prevent bending or curling under the ordinary pressure to which it is subjected.

I prefer to insert the pins 1) before the operation of channeling the sole, but do not limit myself in this particular.

The lips b b are usually formed from the flesh side of the sole, and the pins 12 are therefore inserted in close proximity to the 0pp0. site or grain side of the sole. The grain-sur face of the sole is sufficiently dense and firm to enable it to guide the pins as they are being driven and prevent them from beingdefiected through the surface of the sole in closest proximity to them.

I claim '1. A channeled'inner sole provided with a series of stiffening-pins inserted in its edge and extending across the channeled portion.

2. An inner sole havinga channel or channels formed in its flesh side, and a series of pins driven into the edge of the sole, between the flesh and grain sides, the pins being in close proximity to and parallel with the grain side.

In testimony whereof I have affixed my signature in presence of two Witnesses.

JOHN V. ALLEN.
