July 3l, 1934. J. F. GILKERsoN l-SHOEI Filed Sept. I 20 1953 INVENTOR v avg i MTORNEY Patented July 31, 1934 STATES PATENT OFFICE 3 Claims.

The invention relates to cushion shoes and a method of making the same.

lin that type of shoe wherein the lining and upper are lasted inwardly over the inner sole of the shoe and the outer sole fastened by sewing or nailing directly through the outer sole, lining, upper and inner sole as in McKay and nailed shoes and the outer sole fastened by adhesive to the inner sole and the lasted over lining and upper U as in compo shoes, those parts of the shoe that are lasted over present a harder area to the foot than other portionsand in many instances cause discomfort to the wearer.

vThe object of the present invention is to pro- M vide a cushion shoe construction for shoes of the above type which will cushion the harder areas above referred and which may be expeditiously produced.

A further object of the invention is to provide 2@ certain improvements and modifications of the invention shown and describedin my copending application Serial No. 648,154 filed Dec. 2l, 1932 ier on shoe and method of making the same.

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

Fig. l is a plan view ci a portion of the shoe embodying the invention, parts being broken away;

Fig. 2 is a detail sectional view through the forepart oi a shoe embodying the invention;

Fig. 3 is a detail sectional view similar to Fig.

Fig. 4 is a detail sectional vieu.1 similar to Fig.

2 showing a compo shoe.

According to the present invention, a cushioning layer 5, which is directly incorporated in the w shoe, extends entirely over the complete surface or the inner sole 6, thus forming a perfect cushion for all parts of the foot and thereby eliminating the hard and uncomfortable surface around the outer edges of the inner sole as formed in the ordinary cushion shoe. This cushion 5 is preferably permanently fastened at all points to the inner side of the inner sole 6 as by a suitable adhesive or cement so that there will be no tendency o turning up of the edges of the inner sole. The

said cushion is of soft or sponge rubber which may be of uniform thickness or molded to any desired shape.

A midsole or coversole 'i is secured to the underside of the cushion 5 as by adhesive or in any .m1-'r and with said cushion and the inner sole 6 forms a unit in the manufacture of the shoe.

According to the present process or method, the inner sole 6, Which is fiat and smooth and of the same shape and size as the bottom of the last 8, has the cushioning layer 5 of the same size as the inner sole 6 secured thereto, and the covering layer 7 of the same shape and size as said inner sole 6 is secured to said cushion and these parts are then placed upon the bottom 0f 55 the last 8 and temporarily secured thereto With the sole 6 next to the last. Thereafter, the upper 9 and its lining 10 are lasted inwardly over the edge portions of the sole member including the parts 6, 5 and 7 and are secured in lasted position over said cushion 5 and the part 7 by suitable fastening means as staples ll at the shank and forepart and by tacks at the heel seat or by tacks in place of staples, which fastening means pass through the lasted over parts of the shoe and the parts 7, 5 and 6, it being noted that in the lasting over operations portions of the cushion 5 under the lasted over parts will yield sov that a substantially level and smooth bottom for the shoe is obtained after the same is lasted. By the term upper, I mean to include other usual parts of the lupper such as the counter and the box toe.

The outer sole l2 is then fastened to the shoe by fastening means which also pass through the cushioning layer 5. In the McKay shoe, the forepart and shank of the shoe has the outer sole secured in position by stitching 13 passing through the edge 11i of said outer sole, and the lasted over parts of the upper 9 and lining 10 and through the cushion 5 and the parts 6 and '7, as shown in Fig. 2. At the heel, nails are usually used instead of stitching. In the nailed shoe, nails 15 are used to secure the outer sole 12 as a substitute for the stitching of the McKay, 95 Fig. 3 showing a detail section through the forepart of a nailed shoe. In both of the above forms, some adhesive may also be used between the outer sole and the sole member 7. In the compo shoe the outer sole is secured to the other Mm adjacent parts of the shoe by a suitable adhesive instead of nails or stitching and a detail section through the forepart of this shoe is shown in Fig. 4.

From the foregoing description, it will be noted that not only is the shoe cushioned in the center of the bottom, but as the cushioning material extends outward beyond the fastening means to the extreme edge ofthe inner sole, there is a permanently secured cushion which extends over n0 the entire surface of the shoe and neither this cushion or the members 6 and '7 of the inner sole can shift relative to the other parts of the shoe so that the shoe will hold its shape. The inner sole member 6 is preferably of leather While the cover sole 7 may be of leather, canvas or other suitable material. This covering layer l offers less frictional resistance to the upper materials as they are movedv over the same during the lasting operation than where said material comes in direct contact with the cushioning layer and also improves the anchorage for the fastening means for the outer sole.

It is to be understood that the cushioning layer 5 need not extend into the heel portion of the shoe unless desired.

I desire it to be understood that this invention is not to be limited to descriptive details hereinafter set forth except in so far as the same are specically included in the claims. f

What I claim as my invention is:

1. In a cushion shoe, the combination of a pair of inner soles, a layer of soft rubber at the forepart of the shoe coextensive withv and interposed between said inner soles, an upper having a lasted over edge extending around and'overlapping the outer edge portions of said soles and layer of rubber at the forepart of the shoe, fastening means securing said lasted over edge to said inner soles at the forepart of the shoe and extending through said soft rubber layer, and an outer sole secured to said lasted over portions.

2. In a cushion shoe, the combination of a pair of inner soles, a layer of soft rubber at the forepart of the shoe coextensive with and interposed between said inner soles, an upper having a lasted over edge extendingA around and overlapping the outer edge portions of said soles and layer of rubber at the forepart of the shoe,fastening means securing said lasted over edge to said inner soles at the forepart of the shoe and extending through said soft rubber layer, and fastening means securing said outer sole to said inner soles at the forepart of the shoe and extending through said lasted over edge and said soft rubber layer.

3. Ina shoe having an outer sole and an upper, a cushion insole having a portion of the upper lasted thereon and imbedded therein to present a substantially level bottom surface to which the outer sole is attached, comprising an upper layer and a relatively smooth strong bottom covering layer both of a size to fit the bottom of a shoe and an intermediate layer of resilient lling material substantially co-extensive with said layers and attached thereto throughout its area to prevent relative movement between said upper layer, covering layer, and resilient filling material.
