2 Sheets-Sheet 2 7 Filed Dec. 10, 1935 /L9 TTORNEY and yet rugged, neat in in a slit formed around and arrangement of parts Patented Aug. 24, 1937 UNITED STATES PATENT OFFICE FOOTWEAR Dominick J. Calderazzo, Brooklyn, N. Y. Application December 10, 1935, Serial No. 53,691 3 Claims. 01. 368.5)

footwear, and more construction of non-turned 15 obvious and in part hereinafter pointed out.

The foregoing objects and others ancillary thereto I prefer to accomplish by employing a single piece of leather which serves as an inner and outer sole, the upper or vamp being inserted the edge of the said leather and cemented therein. The upper surface of the said leather is also formed with a lateral extending portion which serves as an arch support when suitably disposed within the slip- 25 per. The forward part of the sole is made flexible by gouging out a portion of the upper'surface thereof. I

The invention accordingly consists in the features of construction, combinations of elements,

which will be exemplified in the construction hereinafter described, and of which the scope of application will be indicated in the following claims.

In the accompanying drawings, in which is 35 shown one of the various possible embodiments of this invention,

Fig. 11 is a View in section taken substantially on the line HH of Fig. 9;

Fig. 12 is a plan view of an inner lining member of Fig. 9 adapted for use in connection with my improved construction;

Fig. 13 is an enlarged detail in section, illustrating a portion of my slipper construction shown in Fig. 8; and

Fig. l lis a view in section similar to Fig. 9, but illustrating a modified form of my invention.

Referring to the drawings, there is disclosed a shoe or slipper construction l5 embodying my invention. Said construction comprises a piece upper 23 and a heel 24. The sole 20 is designed to be of suitable thickness in order to serve as a combination integral inner sole and outer sole to which the vamp 23 is adapted to be attached in a manner to be described as the specification proceeds.

The sole 20 is provided with a slit 25 around the edge thereof disposed substantially midway between the top and bottom surfaces 2| and 22,

areas of the sole '20, the top surface of said extension 38 being flush 2! of the sole 20.

The heel portion of the sole 20 below the slit 25 is formed with a marginal cut away portion-3| which may extend from the outer edge of said sole 20 to substantially theinner limit of the as at 32.

To provide greater resilience and flexibility to the toe area of the sole 20 a centrally disposed portion of the top surface 2| thereof may be gouged out, as at 35, as shown in Figs. 1, 2, and 4 of the drawings. The upper or vamp 23 may be of the type well known in the art, comprising an The bottom edges of the layers 23a and 23b of the vamp 23 are turned in and provided with a layer of adhesive substance 40, such as cement or the like (see Fig. and then inserted in the slot 25, the top and bottom surfaces 2| and 22 adjacent the slit being pressed together and held for a sufficient time to allow the cement to dry. The extension 3i! is curved upwardly as shown, particularly in Fig. 9, to contact the layer 23b to form a reinforcement for the arch portion of the slipper.

A heel 24 of the type well known in the art when suitably placed in position, as shown in Fig. 8 of the drawings, serves to hold the heel portions of the inturned layers 23a, 23b and the counter 23c disposed adjacent the cut away margin 3!. The skived edge 32 permits the said assembled layers to lie flat under the top surface of the heel. The heel 24 may be attached to the sole 20 in any suitable manner, such as by the use of nails 45 driven through from the upper surface 2|.

It is thus seen from the above description that the vamp 23 of the slipper and the heel 24 have been attached to the sole 2% without the necessity of employing stitching, thereby eliminating the costly and complicated stitching machines usually employed in the manufacture of non-turned shoes. It is also seen that the toe portion has been made flexible by means of the gouged out area which is a highly desirable feature in a slipper, while at the same time, the arch portion has been reinforced by means of the laterally extending portion 30.

If it is desired, an inner lining 5i] conforming to 0 the contour of the top surface H of the sole 20 and of slightly larger size may be cementedly attached therein, as shown in Figs. 13 and 14 of the drawings. The heel area of the lining 50 may be inserted in the slit '25 after the nails 45 have been driven into the heel so that the lining will overlie the nail heads.

It will thus be seen that there is provided a device in which the several objects of this invention are achieved, and which is well adapted to meet the conditions of practical use.

As various possible embodiments might be made of the above invention, and as various changes might be made in the embodiment above set forth, it is to be understood that all matter herein set forth or shown in the accompanying drawings is to be interpreted as illustrative and not in a limiting sense.

Having thus describedmy invention, I claim as new and desire to secure by Letters Patent:

1. A slipper construction of the character described, comprising a vamp, and a sole, said sole having a top and bottom surface, means for attaching said vamp to said sole whereby said top surface is adapted to serve as an inner sole for said slipper while said bottom surface serves as an outer sole for said slipper, said top surface being provided with a lateral portion extending beyond said bottom surface, said extending portion being disposed adjacent an inner wall of said slipper in the shank portion of said slipper to serve as a shank reinforcement thereto, and means whereby the front portion of said sole is rendered more flexible than the rear portion thereof, the heel portion of said bottom surface being provided with a recessed margin to permit the bottom inturned edge of the vamp to lie substantially flush with said outer sole surface.

2. A slipper construction of the character described, comprising a vamp, and a sole, said sole having a top and bottom surface, means for attaching said vamp to said sole whereby said top -v surface is adapted to serve as an inner sole for said slipper while said bottom surface serves as an outer sole for said slipper, said top surface being provided with a lateral portion extending beyond said bottom surface, said extending portion being disposed adjacent an inner wall of said slipper between the heel and toe portion of said sole to serve as a reinforcement thereto, and

means whereby the front portion of said sole is rendered more flexible than the rear portion thereof, said last named means comprising a gouged out portion in said top surface of said sole, the heel portion of said sole being provided with a cut away margin to permit the bottom inturned edge of the vamp to lie substantially adjacent the edge of said cut away portion of the heel.

3. A slipper construction of the character described, comprising a vamp, a sole and a heel, said sole having a top and bottom surface, means for attaching said vamp to said sole whereby said top surface is adapted to serve as an inner sole for said slipper while said bottom surface serves as an outer sole for said slipper, said top surface being provided with a lateral portion extending beyond said bottom surface, said extending portion being disposed adjacent an inner wall of said slipper between the heel and toe portion of said sole to serve as a reinforcement thereto, and

means whereby the front portion of said sole is rendered more flexible than the rear portion thereof, said last named means comprising a gouged out portion in said top surface of said sole, the heel portion of said sole being provided with a cut away margin to permit the bottom inturned edge of the vamp to lie substantially adjacent the edge of said cut away portion of the heel, said inturned edge of the upper and said heel portion being held in position by the attachment of the heel.
