Andrews,'Chicago, Ill., and one-half to Morris L. Andrews, St. Louis, Mo." J-- Application October 9, 1944, Serial No. 557,748

This invention relates to shoes and to their manufacture.

The manufacture of shoes is one ofthe oldest arts, and, in the past, numerous attempts have been made to simply the manufacturing operations necessary for the making of shoes to reduce costs. This has been particularly so with regard to childrens shoes since, in many cases, such shoes are outgrown before they are fully worn out.

Past attempts to cheapen the manufacturing costs of shoes, such as childrensshoes, have not been entirely successfuL' In many cases, gluing or cementing operations instead of stitching operations have been resorted tobut these, in general, have had the disadvantage of being ineffective to provide a lasting bond between the shoe parts, or have involved additional manufacturing operations making the method uneconomical, or have involved such construction as to make resoling of the shoe practically impossible.

An object of my invention is. to provide a shoe that is devoid of the above-named disadvantages of prior art methods, and that is simple and economical to manufacture.

A more specific object of my invention is to provide a shoe in which'the parts are cemented together in such manner as to reduce manufacturing 'costs and at the same time make it possible to resole the shoes without too much difiiculty.

A further object of my invention is to provide a novel method for manufacturing shoes that involves few and simple steps.

Other objects and advantages will become apparent from the study of the following specification taken in connection with the accompanying drawing in which:

Figure 1 is a top or plan view of an outsole having a tapered groove or channel on the top surface along and adjacent the margin thereof.

Figure 2 is a top or plan view of a complete shoe including the outsole shown in Figure 1.

Figure 3 is an enlarged, partial, cross-sectional view taken along line III-III of Figure 1.

Figure 4 is an enlarged, partial, cross-sectional view of a heel portion taken along line IV-IV of Figure 2.

Figure 5 is a somewhat enlarged, cross-see 1 Claim. (01. 36-16) illustrate, more clearly, the surfaces that are covered with cement. v

Referring more particularly to Figures 1 and 3 of, theolrawing, numeral I denotes an outer sole on uutsole of a shoe, the top surface of which is trimmed or undercutso as to form a downwardly and outwardly tapered groove or channel 2 ex tending along the margin, somewhat inwardly of and along the entire periphery of the outsole, thus providing an inwardly extending, marginal lip portion or fin 3. The beveled surface 4 of marginal lip portion 3 is substantially parallel to and overhangs a substantial portion of I the tapered or beveled surface 5 extending downwardly from and at an obtuse angle with respect to the top surface of outsole I.

The upper 6 of the shoe, which may be of single or composite layer construction, is secured to an inner sole or insole I along a line of stitching 8, or perhaps a line of stapling, inwardly from the peripheral edge of the upper and insole, so as to provide a common marginal portion 9 which preferably extends outwardly in the same plane as the insole 1, thereby allowing the use of a substantially thick and rigid insole. It is not necessary to last the upper and insole previous to such stitching of their marginal portions, nor is it necessary to trim or bevel,the edges of the common marginal portion 9 before the cementing operation, to be described hereinafter.

The bottom surface of insole l is cemented or glued to the top surface of outsole I, marginal portion 9 being bent downwardly, cemented and seated in the groove 2 by a layer of cement or glue ['0 (see Fig. 6). The upper surface of marginal portion 9 is cemented to the inner beveled surface 4 of lip portion 3. The lip portion 3- thus conceals the stitching 8 or other fastening means that holds the marginal portions of the upper 6 and insole 1 together. Lip portion 3 also protects the bond between the upper 6, insole I and top surface of outsole l and prevents the entry of moisture or foreign matter tending to destroy the bond between the cemented parts.

Inasmuch as tapered groove or channel 2 has appreciable depth, and since surfaces 4 and 5 forming the sidewalls thereof are in confronting relationship throughout most of this depth, the common marginal portion 9 will be completely surrounded and embedded in a layerof cement l0 thereby forming a firm bond.

Fig. 4 shows the heel portion of the upper which is bonded to the outsole in the same manner as the toe portion except that the margin of the counter II is sandwiched between the upper and insole and sewed thereto so asto form part of the common marginal portion 9.

If desired, the top surface of the marginal lip portion may be impressed with ornamentation simulating welt-stitching, stitch separating or wheeling.

By the above construction, after the outsole l is worn, the shoe may be repaired by returning it to the manufacturer or shoe repair shop where the insole and outsole are separated and an entirely new channeled outsole is cemented in position in place of the old one.

It will be seen, therefore, that I an eificient, simple and economical shoe construction and method of manufacture embodying cementing or gluing and eliminating the necessity of stitching the upper to the outsole. It will be apparent that modifications within the scope of the present invention will be suggested to others skilled in the art after having had the benefit of the teachings of the present specification. Hence I do not wish to} be limited except insofar as set forth in the following claim.

-I claim as my invention;

A shoe construction comprising an outsole having a downwardly and outwardly beveled top have provided perimetric portion forming an obtuse angle with the top surface of the outsole and extending inwardly of and alongside in spaced relation to the periphery of the outsole, said outsole also having a marginal lip portion extending inwardly and overhanging a substantial portion of said top perimetric portion in spaced relation therefrom and cooperating'therewith to form aninclined groove having spaced Opposed side walls which are substantially parallel to each other and ex-' tend below the top surface of said outsole, an upper having a margin therearound, an insole having a margin of uniform thickness common with said upper and secured thereto and fitted in said groove; the lower surface of said insole cemented to the top surface ,of said outsole, the common margin fitted in said groove having its I lower surface cemented to the beveled top perimetric portion of the outsole, and the' top surface of said common margin cemented to said overhanging marginal lip portion of the outsole, whereby the common margin of the upper and insole lies within the groove and does not substantially change the parallel relationship of the spaced opposed side walls thereof.

JOSEPH BINDNER.
