WILLIAM H. BAYNAED, OI BBAINTBEE, MASSACHUSETTS, ASSIGNOB OF ONE fiA LF TO mm! H. BEGKWI'I'H, OF VBBOOKIJINE, MASSACHUSETTS.
IN'SOLE' Specification. of Letters Patent.
Patented Mar. 20, 1917.
Application filed December 15, 1916. Serial I'm-137,113.
To all whom it may 0mm.-
.sole, as the case may be, by metallic fasteners.
My present improved insole includes a shank-stiffener made of sheet material, such as leatherboard, that is capable of being sewn. This shank-stiffener is anchored to a foundation element by stitches. The insole also comprises a strip of suitable material such as canvas, to provide the usual stitchreceiving flange to which the pulled-over margin of the upper is anchored. This strip is sewed to the foundation element by a course of stitches, the two marginal portions of the strip being thereafter folded toward each other, and the strip being thereby creased and doubled. I am aware that it is not broadly new to make a stitch-receiving flange in thismanner, but my improvement consists in interposing portions of the aforesaid shank-stiffening element between the foundation element and the stitch-receiving strip prior to sewing the latter to the foundation element. Thus it follows that the shank-stiffening element becomes anchored to the foundation element in the course of sewing the stitch-receiving strip to the foundation element, without any additional operation. The utilization of such stitches for the two purposes de ends primarily upon making the shank-sti ening element of material that may be readily punctured by a sewing needle, and upon making the shankstifi'ening element wide enough to lie within the field of the stitches that are used to anchor the stitch-receiving strip to the foundation element.
- Of the accompanying drawings, which illustrate the present invention in what I now consider'the preferred form;
Figure 1 represents a face view of a partially prepared insole, the view including the foundationelement, the shank-stiffening element (partly broken away at the heel-.
seat), and the stitch-receiving strip sewn to the foundation layer. 7
Fig. 2 represents a facef'view of the complete insole.
Fig. 3 represents a cross section through the structure intersected by line 3-3 of' Fig. 1, the stitch-receiving strip being shown by solid lines in its original fiat condition, and by dotted lines in its creased or doubled condition.
Fig. it represents a cross section through the structure intersected by line 4-4 of Fig. 2.
Fig. 5 represents a cross section through a lasted boot or shoe, in the plane indicated bvline 5-5 of Fig. 2.
The same reference characters indicate the same parts Wherever they occur.
The foundation element of the insole is indicated at 10. This element may be made of any suitable material capable of being readily sewn, but in the present instance it is represented as being wool felt and as being impregnated with a suit'able sizing or stiffening substance that need not be described.
The shank-stiffening element is indicated at 11. It may be made of any suitable material, such as leatherboard, or other substitute for leather, that is capable of being punctured by a sewing needle. It is, however, preferably stiff enough to impart the desired degree of stiffness to the shank portion of a boot or shoe, and in the present instance a stiffening rib 12 is molded therein. I prefer to make the stiffening element 11 of such size as to cover the shank portion and heel-seat portion of the foundation element. In the present instance the outline of the stiffening element 11 conforms to that of the foundation element throughout the shank portion and heel-seat portion, although in Fig. 1 a portion of the stiffening element is broken away to show that the foundation element extends the full length of the insole. i
A strip 13 of canvas or other suitable stitch-receiving material is arranged substantially coextensive with the margin of the foundation element throughout the forepart' and shank portion of the latter, and is anchored to the foundation element by a course of stitches 14. The strip 13 is placed initially in a flat condition as shown by Fig.
3, and the stitches 14 are sewn along its longitudinal median line. Some of these stitches are utilized for the additional pur-\ pose of anchoring the shank-stiffening element 11 to the foundation element 10, and for this purpose the forward portion of the element 11 is interposed between the foundation element, and the strip 13. Thus when the stitches 14 are sewn they necessarily pass through the element 11 as well as the strip 13 and foundation layer 10. 7
After the elements 10, 11 and 13 have been united as shown by Fig. 1, the marginal portions of strip 13 are folded toward each other as indicated by dotted lines in Fig. 3, and the strip is thus creased along its longitudinal median line and doubled in thickness. The upper surface of strip 13, with reference to Figs. 1 and 3, is coated with a substance that is dry under ordinary atmospheric temperature but that becomes adhesive when heated. Thus, after the strip has been sewn and doubled as shown by Figs. 1 and 3, its two layers may be stuck to each other by heating them and pressing them one against the other. A reinforcing layer 15-of canvas or other suitable material is stuck to the foundation element and to the inner layer of strip 13 by adhesive substance represented by a heavy line and indicated at 16. A facing 17 of suitable woven material I I is stuck to the opposite face of the foundation element by adhesive substance that is likewise represented by a heavy line and is indicated at 18. This facing is preferably of larger area than the foun ation element, so that its marginal portion 19 may be folded around .the edge of the foundation and arranged in contiguous relation to the outer layer of the doubled strip 13, as illustrated by Figs. 2, 4 and 5. The heavy line indicated at 20 represents adhesive substance uniting the marginal portion 19 and the outer layer of strip 13. In practice the adhesive substance indicated at 18 and 20 would be applied to the facing 17 before the latter is assembled with the other elements.
The foot-engaging surface of the insole is foundation element.
the facing 17 in Fig. 5. The shoe upper is indicated at '22, and a welt is indicated at 23.
-'stance (not shown) that is commonly used to provide a smooth bearing surface for the outsole.
I claim:
1. An insole comprising a foundation element, a strip of stitch-receiving material arranged substantially coextensively with the margin of the forepart and shank-portion of said element, a, shank-stiffening element of stitch-receiving material, portions of said shank-stiffening element being interposed between said strip and said foundation element, and a course of stitches anchoring said. strip to said foundation element, some of said stitches extending through said interposed portions of said shank-stifiening element, whereby the latter is anchored to said 2. A boot or shoe comprising an upper, an insole having a foundation element, a stitchreoeiving flange, a shank-stiffening element of stitch-receiving material, portions of which are interposed between said flange and said foundation element, and a course of stitches anchoring said flange to said foundation element, some of said stitches extending through said interposed portions of said shank-stiffening element to anchor the latter to said foundation element, and stitches connecting the pulled-over margin of the upper to sald flange.
In testimony whereof I have afiixed my signature.
WILLIAM H. BAYNARD.
