INNEBSOLE.

Application filed June 1,

ToaZZ whomz't may concern: 1 V e it known that. I, ELVTN A.,Hown, citizen of the United States, residing at Boston, State of Massachusetts, have invented new and useful Improvements in Innersoles, of which the following is a specification.

his invention relates to an inner sole and has for its object to provide an article of the character mentioned so constructed that it may be laundered indefinitely without inur J nother object of the invention is to so construct an inner sole that the stiifeners employed therein may be easily removed therefrom when said inner sole is laundered. The invention isjprovided to be used by persons whose feet perspire excessively with the result that the interior of the shoes, especially at the bottoms thereof, become saturated with moisture to such an extent that said shoes become wear, and when the shoes dry out the bottoms thereof become stiff and hard, and often crack and form ridges which also renders said shoes uncomfortable to wear.

The invention consists in the combination forth in the following specification and particularly pointed out in the claims thereof.

Referring to the drawings:

Figure 1 is a plan view of an inner sole embodying the invention, a portion of the upper layers of fabric being broken away to more clearly illustrate the stiifeners located within the inner sole.

F ig. 2 is a transverse section taken on the line 2-2 of Fig. 1.

Fig. 3 is a longitudinal section taken on the line 33 of Fig. l.

' F ig. 41 is a longitudinal section taken on the line 4P4 of Fig. 1.

Like numerals refer to like parts throughout the several views of the drawings.

Inthe drawings, 5 represents an inner sole preferably constructed of an upper layer 6, an under layer 7, and intermediatelayers 8 and 9, all of washable fabric, as, for eX- ample, linen or cotton. -The edge portions of the layers or fabric 6 and 7 are turned inwardly as illustrated in Fig. 2 and sewed together by stitching 10 which extends entirely around the inner sole close to the edge thereof. Other rows of stitching 11, 12, 13, 14 and 15 also extend longitudinally of the inner sole 5 and secure said layers of fabric in the county of Suffolk and very uncomfortable to 1.

together, the stitching 11 and 12 being located adjacent to the edge of theinnor sole and approximately parallel thereto, while the rows of stitching 13, 1 1 and 1.5 are parallelly disposed relatively to each other and located in the central portion of the inner solo. The rows of stitching 13, 14 and 15 not only secure the layers of fabric together, but also form pockets 16 and 17 which extend the entire length of the inner sole 5. The pocket 16 is permanently closed at an end 18 thereof and is open at an end 19, and the pocket 17 is permanently closed at an end 20 thereof and is open at an end 21. The pockets 16 and 17 are so arranged that the open end 19 of the pocket 16 is located adjac'ent to the closed end 20 of the pocket 17, while the closed end 18 of the pocket 16 is located adjacent to the open end 21 of the pocket 17. Stiifeners 22 and 23 constructed of any suitable resilient material, preferably a non-rustable metal, are located in the pockets 16 and 17, respectively, and extend the entire length thereof. The stiifeners 22 and 23 when in position prevent the e tremities of the inner sole 5 from curling or rolling and hold said inner sole extended preventing the extremities thereof from creeping toward thecentral portion of the foot if the inner sole becomes moist and saturated with perspiration.

he device .is laundered as often as may be required at which time the stiffener-s 22 and 23 are removed from the pockets 16 and 17, respectively, and said stiifeners are again reinserted within said pockets when the inner sole is again used. l Vhen the inner sole is laundered, it is impregnated with starch, dried and ironed in exactly the same manner as a collar or cuff. and the smooth surface of said inner sole presents a smooth drv surface with which the stocking contacts. The tendency'is for the feet to perspire the greatest at the toes and heel and the stifleners E22 and 23 prevent the extremities of the inner sole from curling upwardly when the end portions thereof become saturated with perspiration and also prevent said extremities from creeping toward each other and forming ridges and creases at the central portion of the inner sole.

It is evident that any arrangement of stitching may be employed in securing the layers of fabric together so long as said stitching does not interfere with the formation of the pockets l6 and 17.

I claim:

1. An inner sole provided with a plurality of pockets extending longitudinally thereof, an open end of one pocket being located ad- 5 jucent to 2L.ClOSO(l endof another pocket and stifl'eners-loosely mounted Within said pockets and removable therefrom.

2. An inner sole provided with a pair of pockets extending longitudinally thereof,

10 one of said pockets being open at the front end of said inner sole and closed at the rear end thereof and the other pocket being closed 'at the front end of said inner sole and open at the rear end thereof, and stiffeners located Within said pockets and extending the entire length thereof.

In testimony whereof I have hereunto set my hand in presence of two subscribing Witnesses.
