INNERSOLE AND METHOD OF MAKING THE SAME Fred L. Ayers, Waltham, Mass., assignor of twenty-two one-hu'ndredths to Charles G.

Keferstein, New York, N. Y.

Application October 23, 1945, Serial No. 623,992

1 It is desirable that the stitch-securing rib of an innersole for a welt shoe include an integral portion of th innersole blank and such a portion may comprise a lip partly severed from the blank by a channeling operation. A lip formed by channeling outwardly toward the margin of the blank has the advantage that it permits the shoe to be held flat against the sewing machine guide during th inseam stitching operation in a position familiar to the operator and wherein the shoe feeds through the machine without the necessity of any particular care on the part of th operator. 1

A further advantage is that it leaves the outer margin of the blank of its full thickness so that the pull of the upper therearound cannot cause it to bend up and the full thickness of the innersole is effective in holding the upper outwardly in proper position,

One object of the present invention is to provide an outwardly channeled innersole blank in which the channeling may be shallow, thus .to allow the use of thin flexible innersole blank stock, but wherein the rib is formed up by layers of sheet material such as fabric reinforcing the lip, and wherein the rib is sharply inwardly inclined so that it is easy to sew, and when trimmed, adds very little to the longitudinal stiffness of the innersole. 1

A further object is to provide a construction by which the channel lip is suitably reinforced with- 9 Claims. (Cl. 36-22) out requiring a second lip formed by an inward channeling operation in order to cause the rib to take its desired position with reference to the blank.

This application is a continuation-in-part of my application Serial No. 572,173 for Innersole and mehod of making the same, filed January 10, 1945, now abandoned.

For a more complete understanding of this invention, reference may be had to the accompanying drawings in which Figur 1 is an inverted plan view of an outwardly channeled innersole blank.

Figure 2 is a detail sectional view on line 2-2 of Figure 1.

Figures 3 to 6, inclusive, are views similar to Figure 2. but illustrating successive steps in the formation of the completed innersole.

Figure 10 is a fragmentary view partly in section and partly in side elevation showing the bringing together of two strips to be applied simultaneously to the innersole blank to form the construction shown in Figure 9.

Figures 11, 12 and 13 are detail sectional views in the correspondingly numbered section lines of Figure 10.

Figure 14 is a fragmentary perspective view showing the reinforcing strips as they are secured together for application to the innersole blank.

Figure 15 is a view similar to a portion of Figure 5, but showing the modification of Figure 9, this representing the completed innersole securing rib.

Referring to the drawings, in Figures 1 to 8, inclusive, is shown an innersole blank I outwardly channeled on its lower face as at 2 throughout that portion to be provided with a stitching rib, as herein shown around the forepart and shank, to form an inwardly directed channel lip 3. Next there is cemented to the channel face of the blank, as shown in Figure 3, a reinforcing layer comprising a strip of sheet material such as canvas at 4 having an intermediate portion folded together to form a doubl layer 5 and 6 between single layer margins I and 8. The single layer margins I and 8 are cemented to the channel face of the blank I, the flange 1 overlying the lip 3, and the flange 8 overlying the marginal portion of the blank outwardly of the channel. The double layers 5 and 6 are cemented together and pressed into contact while the double layers are outwardly inclined as shown in Figure 3. When' the cement has set, this gives a tendency for the double layers to take their outwardly turned position shownin Figure 3, and if forcibly turned inwardly, tend to resume their outwardly inclined position. If found more convenient, the channeling could be done after rather than before the application to the blank of the reinforcing strip 4. I

Next, the double layer 5 and 6 is turned inwardly and cemented against the margin 1 which, in turn, has been cemented to the lip. This is shown in Figure 4, at the left hand side, the double layer 5 and 6 coated with cement being shown at bent down toward the margin 1, and in the right hand side of this figure, these parts having been brought together.

0n release of these cemented parts, the channel lip 3 is pulled upwardly somewhat by the resiliency of the reinforcing layers 5 and 6 with their cemented bond. This action lifts the lip toward the desired position for ,th inseam stitching BAGBJOO operation, but if desired, and preferably, the lip 8 is further reinforced as by a sheet material reinforcement l0. As shown in Figure 6, this reinforcement extends throughout the width of the innersole between the stitching ribs on opposite sides and extends upwardly adjacent to the outer edge of the rib where it is trimmed off after being applied.

Instead of employing a reinforcing layer II, which extends across the mid-portion of the innersole blank, the reinforcement may comprise a single strip ll folded longitudinally and particularly in the wider portions of the innersole, as at the forepart, presenting an unrelnforced central portion between the adjacent edges of the strip I l at opposite margins of the blank.

It will be noted that with the arrangement thus described, the outer face of the lip is reinforced by three layers of the reinforcement, these comprising the folded layers ii and 8 which are cemented together, and the margin 1 cemented thereto. If desired, however, the inner margin 1 may be omitted, as shown in Figure 8, the outer.

reinforcement then comprising only the outer margin 8 and the folded layers 5 and 6, which are secured together and initially inclined outwardly as shown in Figure 8. When the layers 5 and 8 are thereafter cemented against the outer face of the channel lip 3, two layers only of this reinforcement are secured to the outer face of the lip, but since the layers 5 and 8 were originally cemented together in the outwardly inclined position of Figure 8, their tendency to resume this position acts to lift the lip 3 after they are cemented to the lip. The inner reinforcement such as In or II may then be applied, if desired.

In Figures 9 to 15, inclusive, a modification is shown wherein instead of employing a single strip of sheet material folded on itself to form the double layers 5 and 6, two narrower strips are brought together and cemented face to face in the same relationship. This somewhat simplifies the folding operation and since the double layer is trimmed off after the inseam operation, the final structure is not different. In accordance with this modification, two layers of strip material and 2! are brought together, the strip 2! being folded longitudinally near to its center of width and with the line of fold inwardly facing and cement-coated on its outer face, and the strip 20 being flat and cement-coated on the side facing the strip 2i. Both are applied to the outwardly channeled face of the innersole as shown in Figure 9, the folded strip 2| having its lower layer 22 applied to and cemented to the innersole outwardly of the channel lip 3 and its outer layer 23 cemented to the outer portion of the ad- ,iacent face of the strip 20. The remainder of the cemented face of the strip 20 is secured to thechannel lip 3.

Both strips may be properly guided to the channeled innersole blank as by the guide and folder 25 shown best in Figures 10, 11 and 12, this folder having passages 26 and 21 suitably shaped to present the strips together and to the innersole blank in the desired relationship where they are pressed together as by the pressing and feeding foot 28 so that the double layer comprises the layer 23 and the outer portion of the strip 20, which tend resiliently to take outwardly inclined positions similar to the folded layers I and 8 of the construction shown in Figure 3. The use of one or more pressing and feeding feet 28 for applying reinforcing strip material is well known in the art.

4 Thereafter the double layer may be turned in wardly and cemented to the channel lip 2 and the inner portion of the strip 20 similarly to the construction shown in Figure 5 to form therewith an inwardly inclined stitch-receiving rib. Such an innersole may then, if desired, be rein- .forced with a layer It such as is shown in Figure 6, or the strip H shown in Figure 7. If a construction as shown in Figure 8 be desired. the strip 20 will be narrower and engage only the strip 2| when a plied tothe innersole blank, the passage 28 being correspondingly narrowed.

From the foregoing description of certain embodiments of this invention, it should be evident to those-skilled in the art that various further changes and modifications may be made without departing from the spirit or scope of this invention.
