AUGUST 3. SCHOENKY, OF SOMERVILLE, MASSACHUSETTS, ASSIGNOR TO REECE SHOE MACHINERY COMPANY, OF BOSTON, MASSACHUSETTS, A CORPORATION OF MAINE.

INSOLE AND PROCESS OF MAKING THE SAME.

Massachusetts, have invented an Improvement in Insoles and Processes of Making the Same, of which the following description, in connection with the accompanying drawing, is a specification, like characters on the drawing representing like parts.

Thisinvention relates to a composite insole composed of two layers of thin leather or other sheet material. 1

*It has heretofore been proposed to make acomposite insole composed of an outer member or layer which'has its edge folded over on the body of the material and then bent upwardly therefrom, and an inner layer which has its edge folded upwardly and which is received within the upturned edge of the outer layer. Examples of insoles having this construction are shown in United States Letters Patent to George Coleman, No. 1,062,536, dated May 20, 1913, and to E. H. Taylor, No. 1,14t5,094, dated July 6, 1915. a I The insole of the present invention is of the general type illustrated in the abovementioned patents and the objects of the invention are to provide a novel insole of this type having an inseam-receivingrib so constructed that it can be readily beaten down in:a beating-down machine after the insole has been sewed to the upper and welt, and alsoto provide" a novel method by which this insole can be made.

In making my improved insole, Ifirst make the inner member from a blank of sheet material of the proper size and shape by folding the edge portion of the blank over onto the body thereof. This folded blank is then placed on another blank of sheet material from which the outer member is formed, said two blanks being so positioned relative to each other that the edge portion of the blank for the outer member will project beyond the folded edge of the inner member. The projecting edge of the outer membei' isthen'folded back on itself into contact'with the periphery of the fold- Specification of Letters Patent.

ed blank, the peripheral edge of the outer member being shaped to present a lip. In this folding operation of the outer member, the folded inner member has the function of a die or former to assist in giving the proper shape to the outer member.

In orderto give a better understanding of my invention, I have illustrated in the drawings a selected embodiment thereof which will now be described, after which the novel features will be pointed out in the appended claims.

Figure l'of the drawings is a view of the blank from which the inner member is formed; Fig. 2 shows said blank with the edge portion folded over onto the body thereof; Fig. 3 is an enlarged section on the line 33, Fig. 2; Fig. a shows the blank from which the outer member is formed, said view showing in dotted lines the folded inner member positioned on the outer member; Fig. 5 is a sectional perspective view showing the folded inner member positioned on the outer member before the edge of the outer member is folded; Fig. 6 is a similar view showing the edge of the outer member folded; Fig. 7 is a perspective View of a completed insole made in accordance with my invention.

The inner and outer members of my improved insole are indicated at 1 and 2, respectively, and each of these is made of sheet material which may be either relatively-thin leather or fabric, or any other similar material. The inner member 1 has the edge portion thereof folded back on shown atG in Fig. 1. This blank has the general shape of an insole and is provided near the heel with the inwardly-directed slits 7. The edge portion of the blank 6 from the slit forwardlyis then folded over against the body thereof, as shown in Figs. 2 and 3, the folded-over edge being indicated at 3. The blank from which the outer member 2 is formed is shown in full lines at 8 in Fig- 4:. After the inner member 1 has been formed, as shown in Figs. 2 and 3, said inner member is placed on the blank 8 so that the heel portions of the inner member l and blank 8 coincide with each other; This relative position of the inner member and blank 8 is shown in dotted and full lines Fig. 4. The blank 8 is of such a size and shape that when the inner member is thus positioned thereon, the edge portion 9 of the blank 8 will project beyond the inner member. After the inner member and blank are thus positioned, the projecting member 1. 111 thus folding the projecting portion 9 of the blank 8, the folded inner member 1 of the insole acts as a die or former to assist in giving the proper shape to the folded edge portion of said blank.

It will be understood, of course, that if necessary the blanks may be properly tempered before the folding operation, as is customary where leather or similar sheet material is to be folded. I also wish to state that the folding of the blanks will preferably be accomplished by means of suitable dies which may be heated in the usual manner if necessary to assist in settingthe folds. W' hen this is done, both blanks will be subjected to pressure and heat. to produce and set the folded portions thereof. The inner and outer members may be secured together in any suitable way. I will, preferably, however, apply a coating of ad hesive material to the face of the folded inner member 1 that contacts with the blank 8 and will subject the inner and outer membersto pressure either during the folding.

One advantage of my improved insole is that it provides an inseam-receiving rib which furnishes ample strength to hold the inseam stitches, but which can be readily flattened out, thus avoiding the presence of an objectionable rib beneath the inner sole of a shoe which often produces. more or less discomfort to the wearer. It will be noted that the strength of the inseain-receiving rib is the combined strength of the portion 5 of the outer member and the infolded portion 3 of the inner member, and even when both of these members are made of thin leather or fabric, the combined strength of both furnishes ample strength to hold the inseam stitches. It will also be noted that the portion 8 of the inner member is folded down against the body thereof'so that the upstanding portion of the rib is simply the portion 5 thereof. Inasmuch as th outer member can be made of relatively-thin material, the action of the usual beatingdown machine on the lasted shoe will be to fold the lip 5 over outwardly, thus making a relatively-fiat rib which will not cause any discomfort to the wearer of the shoe. 7

I claim:

1. The method of making a composite in- I beyond the edge of the folded blank and then folding said projecting portionof said latter blank back onto the body thereof and forming the peripheral edge into alip;

2. The method of making acomposite insole comprising an inner and an outer member which consists in folding the edge por tion of a blank for the inner member over onto the body thereof, placing said'folded blank onto the blank for the outer member with theedge of said latter blank projecting beyond the edge of the folded blank and then folding back on itself the portion of said projecting edge immediately circumjacent the edge of'the folded blank and forming the peripheral portion of said projecting edge portion into a lip.

3. The method of making a composite insole comprising an inner and an outer member which consists in folding the edge portion of a blank over onto the body thereof, attaching said folded blank to another blank with the edges of said other blank projecting beyond the edge of the folded blank and then folding the portion of said projecting edge immediatelv circumjacent the edge of the folded blank back on itself and into contact with the periphery of said folded blank and forming the peripheral edge of said proj'ecting portion into a lip.

4. A composite insole comprising an inner member having the edge portion thereof folded back onto the body thereof and an outer member having the edge thereof projecting beyond the periphery of the inner member and formed by folding back on itself the portion of the outer member directly circumjacent theinner member, the peripheral edge of said outer member being free and forming a lip.

In testimony whereof, I have signed my name to this specification.
