2 Claims.

This invention relates to improvements inshoes, and more particularly to children's soft soled shoes, and has for itsprincipal object to provide a shoe of this kind which can be cheaply made of the softer and more flexible grades of leather or like material and which is durable and neat in appearance.

Another object of the invention is to providea shoe of this kind in which the inner and outer soles are secured to each other and to the upper solely by means of cement, thereby eliminating pegs or stitching from the sole, which are liable to cause discomfort to the wearer.

Still another object of the invention is to provide a shoe of this kind having an inner sole to which the upper is secured by cementing, an outer sole having a welt cemented directly to its upper surface at its outer edge and which is cemented directly to the inner sole and upper.

A still further object of the invention is the provision of a shoe of this kind having an endless welt secured directly to the outer sole and serving to reinforce the outer edges of said outer sole, and the inner sole and upper being cemented directly to said outer sole.

To these and other ends, the invention consists in the construction and arrangement of parts that will appear from the following description when read in conjunction with the accompanying drawing, the novel features being pointed out in the claims at the end of the specification.

In the drawing:

Fig. 1 is a side elevation of a shoe constructed according to one embodiment of the invention;

Fig. 2 is a transverse section taken substantially on line 2-2 of Fig. 1;

Fig. 3 is a plan view of the outer sole showing the welt cemented thereto;

Fig. 4 is a transverse section of the same taken substantially on line 4-4 of Fig. 3;

Fig. 5 is a fragmentary detail illustrating the relation of the inner sole and upper to the outer sole and welt, and I Fig. 6 is a transverse section of a shoe illustrating a slightly modified construction.

Referring particularly to the drawing, in which like reference numerals refer to the same parts in all views, 1 indicates the upper of a shoe, constructed in the usual manner of soft flexible material. The lower edges of the upper are turned under the inner sole 2, to which it is secured preferably by means of cement. The inner sole and the upper are secured as a unit preferably by means of cement toan outer sole 3. The outer sole is made of soft flexible material and is slightly larger in area than the inner sole 2 so as to project beyond its-outer edges.

Secured to the upper face of the outer sole 3, flush with its outer edge, is an endless welt 4. The inner openingof the welt is of substantially the same size and shape as the inner sole, so that the upper is arranged between its inner edge and the outer edge of the inner sole. The welt is cemented to the outer sole and may have its upper inner edge skived off, asshown in the drawing, so that a plane surface is presented to the outer face of the upper where engaged thereby. The lower outer edge of the inner sole is also skived for the same purpose.

In practice, it has been found to be advantageous to cut the inner sole and the endless welt from the same piece of material at one operation with the same tool. In this maner, an endless welt is formed having anouter margin of the shape and size of the outer sole, an inner margin of the shape and .size of the inner sole and the width of which represents the difference in size between the inner and outer'soles. The welt is slightly shrunk by the action of the cement in drying so that in theassembled shoe its inner edge projects slightly under the outer edge of the inner sole, as shown in the drawing, so that the bent portion of the upper is engaged between the skived edges of inner sole and welt.

Adjacent the inner edge of the upper between the inner and outer soles, said soles are separated from each other a distance equal substantially to the thickness of the material of the upper, forming a cavity at 5. This andother cavities which may occur between the soles are filled with a suitable filler, such as an excess of the cement used in cementing the outer sole to the inner.

The welt applied as herein described serves to reinforce the outeredge of the outer sole, thus making possible the use of softer and more flexible leather in the soles of the shoes than has heretofore been possible. It also prevents the outer edges of the sole from curling or other distortion, and enables the maker to tool and finish the soft material in the usual manner.

If desired, the shoe may be provided with a heel, as shown in Fig. l, bymeans of a lift 6 of soft flexible material inserted between the heels of the inner and outer soles and secured to both by means of cement. The lift 6 is preferably made as a part of the outer sole to which it is secured, and the welt 4 applied to the outer sole and the lift 6 so that the welt 4 at the heel is arranged between the lift 6 and the inner sole and upper. Since .the lift 6 serves to reinforce if desired.

and stiffen the outer sole at the heel, the welt! may be omitted from that part of the outer sole,

In Fig. 6, a slight modification is shown, in which the entire space between the inner'and outer soles and between the inner edges of the upper is filled with a soft resilient material, such as ground cork 7. This layer of ground cork is \secured in position between the inner and outer 31) on, an upper having a portion turned under the to the wearer. Although the invention has been described with reference to certain details of construction, it

will be understood that this application is intended to cover such changes or modifications as come within the spirit of the invention or scope of the following claims.

We claim: 1. A shoe comprising an inner sole offiexible material having its outer edge skived to form a downwardly and inwardly inclined surface thereouter edge of the inner sole in contact with its lowersurface and said downwardly and inwardly inclined skived edge and cemented to its lower surface, an outer sole of soft flexible material cemented to said inner sole and the inwardly projecting portion of the upper so that said portion iscemented to and between the innerand outersoles, said outer sole projecting outwardly beyond the outer edge of the inner sole, and an endless welt cemented to the upper side of the projecting portion of the outer sole and having its inner edge skived to form a downwardly and inwardly inclined surface thereon arranged in contact with the inwardly turned portion of the upper opposite the downwardly and inwardly inclined skived surface on the inner sole so that the turned portion of the upper is engaged between the sklved edges of the inner sole and welt. 2. A cemented shoe comprising an insole hav- A ing an inwardly and downwardly tapering marginal surface, an upper having its marginal portions extending inwardly over'said surface and suitably secured to the insole, and an outsole having a rand cemented to its upper surface, said rand extending around the margin of the outsole and having an inwardly tapering surface cemented to the inwardly turned portion of the upper.
