SHOE

Application filed August 5, 1929. Serial No. 383,610.

The invention relates to shoes and more particularhy to Goodyear welt shoes having sewed heel seats.

The general object of the invention is to provide a cushion spring heel construction for Goodyear welt shoes having sewed heel seats which may be expeditiously incorporated in shoes of this type without any change in the factory equipment and which does not materially increase the cost of the shoe, but produces a far more comfortable and healthy shoe than any shoes of this type heretofore proposed and one which is especially suitable for childrens use and for so-called athletic shoes.

A further object of the invention is to provide a combined `cushion heel andiexible shank construction for Goodyear welt shoes having sewed heel seats.

This application is a continuation in part of my prior United States application Serial No. 350,023, iiled March 26, 1929, but in addition thereto the present application embodies certain improvements over said prior application -in that the cushioning material is extended over the inseam ridge to lfurther increase the wearers comfort.

The invention further consists in the several features hereinafter set forth and more particularly defined by claims at the conclusion hereof.

In the drawings Fig. 1 is a bottom plan View of a shoe embodying the invention, parts of the outsole being broken away;

Fig. 2 is a detall side elevation view of the shoe, parts being broken away and parts being shown in section;

Fig. 3 is a detail sectional view taken on o the line 3-3 of Fig. 2;

Fig. 4 is a` detail perspective View of the cushion spring heel and fiexible shank member' Fig. 5 is a perspective View of one of the parts associated with the heel portion of said member; I

s Fig. 6 is a detail, vertical, sectional View of a shoe provided with the cushion spring heel constructionembodying the invention;

Fig. 7 is a perspective view of the spring heel construction shown in Fig. 6, parts being broken away and parts being shown in section.

As previously noted, this invention relates to Goodyear welt shoes in which the heel seat is sewed and in which no nails are used in attaching the heel to the heel seat and as such the shoe includes the usual upper 10 which may have a lining 11 and counter 12 associated therewith, these parts being secured in the usual manner to the Hangs portion 13 of the insole 14 and to the welt 15 by the inseam stitching 16, the welt 15 extending about the entire shoe.

Usually in shoes of this type the space 85 formed between the inseam ridges 17 and the bottom. of the insole is filled with the usual bottomiiller, a relatively stiff leather spring heel is disposed over the heel seat and eX- tends across under the welt and the outsole is secured to the shoe by stitching it to the welt at the toe and shank portions of the shoe and by stitching it to the spring heel and the welt at the heel seat portion of the shoe, which provides a spring heel shoe without any special cushioning properties, as neither the bottom filler nor the spring heel possess such properties.

According to the present invention, after the inseaming operation either the spring heel construction shown in Figs. 6 and 7 is used in place of the usual unyielding leather heel, or the spring heel and flexible shank construction shown in Figs. l to 5, inclusive, is used.

Referring first to Figs. 1 to 5, inclusive,' a piece of soft cushionin material 18, preferably molded sponge ruber, is formedto provide a heel portion and a iiexible shank portion 20'and from Figs. 3 and 4 it will be noted 90 that the heel portion includes a cushion part 21 which extends up into the space formed between the inseam ridges 17 and the bottom of the insole 14 and takes the place of the usual bottom filler and includes the part 22 which 95 forms the spring heel proper and that this part lprojects beyond the cushion part 21 forming a flange 23 which extends over the inseam ridge 17 at the heel seat. It will also be noted from Figs. 1 and 2 that the iexible 100 shank portion 2O 1s disposed in the space between the inseam ridges 17 and the bottom of the insole in the space usually occupied by4 toe portions of the shoe is filled with'the usual bottom filler 19.

The spring heel construction is completed by aiiixing to the spring heel part 22, with rubber cement or otherwise, a member 24 of stiffer material, preferably relatively denser rubber, such as is used in rubber heels, said member 24 forming a marginal or enclosing frame for the part 22 and extending around the heel beneath the welt 15 and initially secured to the welt by suitable adhesive.

With the parts thus assembled the usual outsole 25 is secured to the shoe by stitching 26 extending through the welt and outsole at the front and shank portions of the shoe, as shown in Fig. 1, and extending throughthe welt 15, member 24 and outsole at the heel portion of the shoe, as shown in Figs. 1 to 3, inclusive.

While it has been noted above that the piece 18 is secured to the shoe first and the member 24 then secured to it, these parts may first be vadhesively secured together by cemening or vulcanizing them together, if des1re y provided it has been found that easier iitting of the parts to the shoe is obtained by securing them thereto as first described. In either case the parts 18 and 24 are firmly united in the complete shoe.

Referring to Figs. 6 and 7, where only the cushion spring -heel is desired the liexible shank portion 20 of the first-'described construction is omitted so that the spring heel or vulcanizing to form lthe includes pieces 27 and 28 which may be initially adhesively united either by rubber cement unit construction shown in Fig. 7 and 4as such secured to the shoe, or which may be separately secured in position as in the first described construction. As in the first described construction, the piece 27' of resilient material, preferably mb'lded sponge rubber, is formed to rovide a cushion part 29 which extends up into the space formed between the inseam ridgesl? and the bottom of the insole 14, as shown in Figs. 6 and 3, and forms the spring a Hangs 30 extending over t e inseam ridge 17, the piece 28 being the same as the piece 24 and similarly secured to the piece 27 and to the welt and outsole, the space forward of the heel in the finished shoe having the usual bolttom filler 31 between the insole and out- SO e.

lIt will be noted `from Figs. y2 and 4 that the front edge 32 of the shank portion 20 is beveled inwardly to prevent the formation but where the iiexible shank portion is having tlie part 30, which.. heel proper, provided with of a ridge at this point when the outsole is attached and that the front edge 33 of the piece 26 and the front edges 34 of each of the parts 24 and 27, are similarly beveled for a similar purpose.

I desire it to be understood that this invention is not.to be limited -to any particular form or arrangement'of parts except in so far as such limitations are specified in the claims.

What I claim as my invention is:

1. In a Goodyear welt shoe having a sewed heel seat with the usual welt, inner and outer soles, a spring heel construction interposed between the inner and the outer soles comprising a soft rubber' member providing a spring heel portion,land a stitch-receiving marginal frame member of relatively stiffer material surrounding and secured to the outer edge portion of said spring heel ,portion and extending beneath the welt.

3. In 4a Goodyear welt shoe having inner and outer soles and .a welt inseamed to the upper materials at the heel seat, a spring heel construction interposed between the inner and outer soles comprising a soft rubber member providing a cushion portion and a spring heel portion extending under the inseam ridge, and a stitch-receiving marginal frame member of relatively stiffer material surrounding the outer edge portion of said spring heel portion and extending beneath the welt.

4. In a Goodyear welt shoe having a sewed seat with the usual welt, inner and outer soles, a spring heel construction interposed between the inner and outer soles com rising an inner member of sponge rubber, an an outer stitchreceiving member of relatively dense rubber adhesively secured to the outer edge portion of said inner member and extending beneath l the welt.
