SHOE AND NSOLE THEREFOR Filed April 8, 1959 2 SheeLs-Sheel l 'III/Ill VII/IIA Rw INVENTOR ATTORNEYS Dec. 24, 1940. F. sBlccA SHOE AND INSOLE THEREFOR Filed April 8, 1959 2 Sheets-Sheet 2 INVENTOR ffm /v/f B/CCA BY M7@ Mr ATTO R N EYS Patented Dec. 24, 1940 UNITED STATES PATENT OFFICE 9 Claims.

This invention relates to shoe and insole therefor and the manufacture thereof. This invention relates especially to shoe construction wherein the upper has along the lower margin thereof portions of substantially differing thickness as, for example, in the case of shoes having a plurality of spaced marginal portions such as straps secured between the insole and sole with openings between the straps along the margin of the sole of the shoe.

Heretofore serious difficulties have been incident to the manufacture of shoes of the character referred to due to unsightly gaps between the insole and sole portions of the shoe and due to uneven marginal portions of the insole of the shoe which cause discomfort to the wearer. It is a purpose of this invention to overcome difficulties of the character referred to.

It is a feature of this invention that novel lmeans are employed along the margin of the shoe and between the insole and sole portions thereof which serve to prevent the occurrence of unsightly gaps between the sole and the insole portions of a shoe and which cause the insole of the shoe to be even along the margin thereof, notwithstanding the fact that the upper of the shoe has spaced portions such as straps along the lower margin of the upper with openings therebetween, which spaced portions are disposed over the insole and between the insole and the sole of the shoe. Further features of this invention relate to the provision of an insole having a strip of deformable material such as sponge rubber along the margin thereof. Additional features of this invention relate to the manufacture and assembling of the sole, insole and upper portions of a shoe so as to achieve the purposes and advantages referred to hereinabove.

Further purposes, features and advantages of this invention will be apparent in connection with the following description of certain specific illustrative embodiments of this invention shown in the accompanying drawings wherein Figure 1 is a perspective view of the insole part of a shoe embodying this invention, with the insole proper, stiiiener and strip of deformable material separated for purposes of clarity;

Figure 11 is a fragmentary sectional view similar to Figure 6, except for the inclusion in the assembled shoe of an insole of the modified type shown in Figures 9 and 10.

Referring to the embodiment of this invention shown in Figures 1 to 8, the insole I2 may be of any suitable material such as leather, rubber, fibrous composition or the like. The insole is shown as being optionally provided with a beveled portion I3 at the ball of the insole around an opening that is covered by sheet I4. The insole is preferably provided with a stiffener I5 which can be attached to the insole along the heel and shank portions thereof by any suitable means such as cement and/or stitching Il. Along the marginal portion of the insole is a strip I6 of substantial thickness of deformable material such as readily deformable rubber, e. g., sponge rubber. In the particular embodiment shown the strip of sponge rubber has a thin fabric backing I1 cemented thereto. The strip of sponge rubber I6 and backing I1 are stitched along the underside of the margin of the insole by stitching I8. A binding indicated generally by the reference character I9 is placed around the margin of the insole so as to cover the edge portion of the insole and the strip I6. The binding .in the embodiment here shown consists of a thin fabric 20 underlying and cemented to a sheet 2| of material such as leather which presents an ornamental external surface. The binding is attached to the margin of the insole by any suitable means such as stitching 22.

In the shoe shown in the accompanying drawings the upper is indicated generally by the referstrap members, each strap member consisting of several thicknesses or layers of material such as leather or fabric, or both, the different layers being united together as by stitching 23, or by a cement, or both. The lower margin oi the upper consists of spaced portions 25 with openings 24 of various sizes and shapes therebetween. These spaced marginal portions 25 of the upper are disposed over the insole (see particularly Figure 6) and lie between the margin of the outsole 26 and the margin of the insole I2. Referring particularly to Figure '7, it is to be noted that the strip i6 of deformable material is at and between the portions 25 of the upper along the insole of the shoe and that the strip i6 is compressed where the portions 25 of the upper occur so as to be of substantially reduced thickness as compared with the portions of the strip along the margin of the shoe where the openings between the portions 25 of the upper occur.

The outsole may be attached to the insole and to the portions 25 of the upper and the portions 25 of the upper may be secured to the lower side of the insole by any suitable means such as ad hesive 21. Instead of an adhesive any other securing means may be used, for example, stitching. Overlying the insole a suitable sock lining 28 may be used. If desired, the sock lining 28 may have a small seam or folded back portion along the margin.

Using the construction hereinabove described, it is possible to eliminate gaps between the outsole and insole portions of the shoe. Notwithstanding the fact that the straps out of which the upper is made have portions 25 comprising a plurality of layers of leather interposed between the outsole and the insole along the margin of the sole of the shoe and that said portions are spaced apart with openings therebetween, the strip i6 of deformable material compensates for the tendency of the portions 25 to unduly separate the margin of the insole from the margin of the outsole between said spaced portions of the upper due to the fact that the deformable strip is compressed to reduced thickness where the portions 25 occur. Notwithstanding the tendency of the portions 25 to separate the margins of the outsole and insole the strip I6 tends to cause the space between the insole and outsole along concurrent margins thereof where the portions 25 of the upper do not occur, to be substantially completely lled. In this manner unsightly gaps between the margins of the insole and outsole along the margin of the shoe are eliminated. Moreover, the upper surface of the insole is made more even so that there is no risk of the shoe being uncomfortable to the wearer due to irregularities in the insole caused by the portions 25 of the upper.

While an upper of a shoe such as that shown in Figure 8 can be made in any suitable manner, it is preferably made by first stitching the straps 30 to a sheet 3| of leather or other suitable material having the general shape desired for the upper of the shoe. The straps 30 can be built up, if desired, as by the use of a strip of fabric or other material 4| and the straps have overlying portions as shown. Sheet 3| can be made up in one piece or can be made up in a plurality of pieces which are subsequently stitched together as by stitching 33. If there is any part of the shoe which is to protrude from the upper such as the buckle strap 34, a separate piece of sheet material 35 can be stitched thereto. After 2,226,392 .ence character 29 and consists of a plurality of the upper has been made in this way the sheet material 3| can be cut away along the edges of the straps 30 so as to produce an upper in the form of openwork and of the type shown in Figure 8.

The upper is assembled with the outsole and insole parts of the shoe in any desired way with the strip I6 of deformable material between the insole and outsole along the margins thereof to produce a shoe construction of the character mentioned above. T'he insole is preferably first formed with the strip I8 of deformable material secured thereto prior to the final assembly and securing together of upper, insole, and outsole parts of the shoe. In the assembly the marginal portion of the shoe is subjected to suicient pressure to compress the strip I6 of deformable material so as to make it of substantially reduced thickness where the portions 25 of the upper occur between the outsole and insole parts of the shoe. If the upper is lasted over the insole, the portions 25 of the upper are subjected to pressure during the lasting operation so as to compress the strip I6 where the strip I6 is between the portions 25 and the insole. The upper, outsole and insole parts of the shoe may be secured together using any desired securing means such as stitching, cement, nails or the like, or any desired combination of such securing means. A heel 42 is secured in place in any desired way.

An alternative embodiment of this invention is shown in Figures 9, 10 and 11. Instead of sewing a strip of deformable material to the margin of the insole and then placing a common binding around the margin of the insole and around the strip of deformable material, the binding which is used can be made up so as to include a layer of deformable material. As shown in Figures 9, 10 and 11, the insole |2 has a binding secured to the margin thereof by the stitching 35. 'I'he bindingV includes a layer 3'|of substantial thicknesswhich is made of some deformable material such as sponge rubber. Overlying this layer is a thin layer 38 of fabric and an overlying layer 39 of some suitable material such as leather or rubber presenting an ornamental outer surface. If desired, the different layers can be bonded together by a suitable cement. When the construction shown in Figures 9, 10 and 11 is used the deformable material on the underside of the insole is compressed r where the portions 25 of the upper occur in the manner referred to hereinabove. The deformable material in the same plane as the insole along the edge thereof permits the upper to be pushed snugly against the edge of the insole so as to present an attractive and substantially uniform edge along and adjacent the margin of the outsole of the shoe. It will be observed from Figs. 7 and 8 for example that the degree of resiliency required of the resilient or deformable material is such as to cause it to press permanently against all adjacent parts of said sole, insole and straps between which it lies and to ll permanently all spaces between said adjacent parts.

While reference has been made to the use of rubber, e. g., sponge rubber, as a preferable material for the strip or layer of deformable material, other readily deformable substances or compositions may be used which may be either of a plastic, elastic or resilient character. The material of the deformable strip should be capable of being deformed and compressed under pressures that can be used in assembling the upper, insole and outsole portions of a shoe.

Normally in the practice of this invention it is desirable to secure the strip of deformable material to the insole before the insole is assembled with the other parts of the shoe, thus producing a preformed insole having the uses and advantageous characteristics referred to herein. This, however, is not essential in the practice of this invention. Moreover, the strip of deformable material may be positioned so as to underlie the portions 25 of the upper and be between these portions and the outsole. In general, the positioning of the strip of deformable material should be between the insole and the outsole of the shoe along the marginal portions thereof at and between the separated portions of increased thickness of the upper and thereby compensate for the tendency of the said separated portions of the upper such as portions 25 to unduly separate the marginal portions of the outsole and insole portions of the shoe along the margins thereof.

While this invention has been described above in connection with an upper having lower marginal portions which are spaced leaving openings therebetween, it is apparent that some of the advantages of this invention may be availed of whenever the upper is produced so as to have along the lower margin thereof portions differing substantially in thickness. For example. if the upper when in the condition shown in Figure 4 were to be assembled with the sole and insole portions of the shoe without cutting away the sheet material 3l between the straps 30, the shoe construction according to this invention would still be advantageous in compensating for the differences in thickness of the marginal portion of the upper that occurs between the insole and outsole portions of the shoe.

The materials out of which the outsole, insole and upper part of the shoe are made are, of course, optional in the practice of this invention. Any suitable material may be used such as leather, fabric, fiber composition, rubber and the like, or any combination of these materials. While the specific types of binding materials for the margin of the insole have been described herein, it will be understood that the binding materials can be made of a single or of a plurality of layers, as may be desired. Moreover, binding materials may even be omitted. While this invention has been described in connection with a ladys shoe, it is apparent that this invention may be embodied in any type of shoe, sandal, slipper or the like. More generally, it is to be understood that the specific embodiments of this invention as shown in the drawings and described herein are merely illustrative and that structures embodying this invention are subject to considerable variation within the scope of this invention. The scope of this invention is to be governed by the language of the following claims.
