Filed April 18, 1958 L 3mm Lew/s KRAMER Admvr United States Parent ELASTIC SUPPER Lewis Kramer, Philadelphia, Pa. Application April 18, 1958, Serial No. 729,377 1 Claim. (Cl. 36-9) This invention relates to an elastic slipper for various sizes of feet.

t is an object of the invention to provide an'elastic slipper capable of stretching to a considerable degree to conform to various sizes of feet.

It is a further object of the invention to provide an elastic slipper in which a principal component is the base and a slipper constructed on a given size base has a potential for stretching to conform to a rather wide range of sizes of feet.

Still other objects, advantages, and novel features of the elastic slipper according to the present invention will become apparent from the following description, taken in connection with the accompanying drawing, in which:

Figure 1 is an under plan view of the elastic slipper according to the present invention;

Figure 2 is a vertical sectional view on the section line 22 of Figure 1;

Figure 3 is a transverse sectional view on the section line 33 of Figure l; and,

Figure 4 is a detail plan view on the line 4-4 of Figure 2.

Referring now to the drawings in detail, and to Figure 2 in particular, the elastic slipper according to the present invention is comprised in part by an upper 10. This upper is made of a suitable knitted fabric, or a Helenca yarn, that will stretch. At its top edge the upper may have an elastic reinforcing and ornamental band 18, of cotton and rubber, around which is circumferentially wound a bright metallic thread 19, and which is suitably stitched to the upper, to provide for a yielding hugging fit. This elastic reinforcing and ornamental band would be applied by a Merrow machine.

The sole is made in three (3) parts, the front and rear parts being identical in construction. These latter parts are each comprised by an intermediate layer 13 of foam or sponge rubber, such as neoprene, in outsole 14 of leather, leatherette, or suedine, and an insole 15 of cushioning material, felt or wedding. The outsole 14,


intermediate layer of sponge 13, and the insole 15 are secured together in any suitable manner, such as by an adhesive and heat fusion. The upper 10 has an inturned edge at 11 to which the front and rear sections of the sole are secured by a row of stitching at 12 running perimetrically of the sole. This row of stitching is either a zig zag or a straight needle stitch, such as is made on a Merrow machine.

A third or shank section of the sole, which is positioned in the area that normally underlies the instep of the foot, is comprised by a thick piece of elastic fabric 16. This third section of the sole is also secured to the inturned edge 11 of the upper by the same row of stitching 12 that secures the front and rear sections of the sole to the upper. At its opposite ends the third section of the sole is secured to the front and rear sections of the latter by double rows of stitching 17.

It will be apparent that the elastic slipper according to the present invention will yield, both transversely and longitudinally, to accommodate various sizes of feet by reason both of the elastic upper 10 and the longitudinal stretching feature of the sole provided by the intermediate or shank section 16.

Having now fully described my invention, what I claim as new and useful and desire to secure by Letters Patent of the United States is:

A slipper comprising a uniform continuous upper of elastic material, and a sole attached thereto, the upper extending upwardly along the entire periphery of the sole, the upper margin of the upper being defined by an aperture about which is circumferentially wound a bright metallic thread within which is contained an elastic reinforcing and ornamental band and which confers a yielding, hugging fit on the upper, with said sole comprising sections secured at the heel and toe ends of the upper, each section comprising an outsole of pliant material, an intermediate layer of spongy material, and an insole of cushioning material, and a resilient section formed of elastic fabric positioned intermediate said first two sections and secured at its opposite ends to said first two sections.
