MOLD FORMING SHOE Filed Dec. 27, 1955 INVENTOR. BENJAMIN B. DUBNER ATTO/5MM;

United States Patent Ofiice Patented `lune. 4, 1957 2,794,270. MOLD FORMING SHOE Benjamin B. Dubner, New Hyde Park, N. Y. Application December` 27, 1955, Serial No. 555,431 3 Claims. (Cl. 36-2.5)

This invention relates to new and useful improvements in shoes.

More particularly, the present invention proposes the construction of an improved sock lining for shoes which will t the wear-er regardless of what type shoe or foot.

As a further object, the present invention proposes forming the sock lining so that it can be placed in any shoe after manufacture of the shoe and does not have to be built into the shoe at the time the shoe is made.

Still further, the present invention proposes constructing the sock lining and placing it in a shoe so that a molding material injected between the intermediate portion of the lining and the shoe will come up the sides as well as cover the bottom to compensate for diterent size feet and to give a snug t for such shoes as sport shoes, ski boots :and shoes requiring a broad forefoot and a narrow heel.

Another object of the invention is to provide structure which will make the amount of molding material automatically correct, the molding material varying directly with the feet and shoe spaces between the lining.

A further object is to provide a structure wherein the mold of the shoe to the foot is set while the foot is at rest so that the foot can be held in a correct position and so that the molding material can be added after the foot is in the shoe to prevent distortion of the molding material as the foot is squeezed into the shoe.

Another object of the invention proposes providing a structure whereby an accelerator can be inserted before the molding substance or with it to reduce the molding time to a minimum.

Still further, the present invention proposes providing a structure whereby molding material can easily and conveniently be injected between the shoe and flexible lining and will not cause the shoe to be too tight since the molding material will only till the natural spaces in the shoe between the lining and the shoe after the wearers foot is in the shoe.

For further comprehension of the invention, and of the objects and advantages thereof, reference will be had to the following description and accompanying drawings, and to the appended claims in which the various novel features of the invention are more particularly set forth.

In the accompanying drawings forming a material part of this disclosure:

Fig. 1 is a perspective view of a shoe constructed and arranged in accordance with the present invention.

Fig. 2 is a top plan view of the structure shown in Fig. 1.

mFig. 3 is a side and top perspective view similar to Figs. l and 2.

Fig. 4 is a bottom plan view of the shoe shown in Figs. 1, 2 and 3.

Fig. 5 is a sectional view taken on line 5-5 of Fig. 4, parts being omitted.

Fig. 6 is a view similar to Fig. 5 but showing the space between the sock lining and sole and sides of the shoe lled with molding material.

Referring more particularly to the drawings, a preferred form of' the invention is illustrated in Figs. l to 6, inclusive.

A shoe 15has an outerA sole 16 With a shank 17, a heel- 18, an innerrsole19, and an upper 20 with sides `21A and'.v 22. Shoe V15, 'as illustrated, is` a ladys slipper but may be any type yor style off shoe.

An injection `opening 29 is formed in the shank portion 17 `of the outer sole 16 and is aligned with a similar opening 30 in the inner sole 19 so that suitable molding material 31 can be injected by a suitable tool into the space 2S between the lining and the sides `and inner sole of the shoe. The molding material may be liquid latex mixed with zinc oxide `and wood flour, or any other suitable molding material. The present invention contemplates that the wearers foot be first inserted into the shoe so that the space 28 will assume the contour of said foot, Iand while the foot is still in the -shoe the molding material is injected. After the molding material has set land hardened, the foot is withdrawn from `the shoe `and the injection opening 29 is closed by a plug 32 as shown in Figs. 4 and f6. The shoe will thus be molded to lit the wearers foot, the molding material conforming to the natural contour of the foot.

In 4accordance with the present invention, a sock lining 23 of llexible leather 'overlies the upper surface of the inner sole 19 and the inner surfaces of the sides 21 and 22 and rear portion 24 of the shoe upper and assumes substantially the shape of the interior 'of the `shank and heel portions of the shoe. This is accomplished by slitting the lining 23 Iat its heel portion and slightly overlapping the edges of the slit Ias indicated at 25. The peripheral edge 26 of the side and heel portions of the lining are secured to the inner surf-aces of the sides and heel portions of the sh-oe upper preferably by a suitable cement, leavin-g the `central portion 27 and the sides iof the lining unattached and thereby provide a space 28 between the lining and inner sole 19 land sides 21 and 22 of the shoe. This lining 23 is Iof such construction and rshape that it can be readily inserted into any shoe whether new or old, and by merely drilling the necessary holes in the outer and inner soles, the invention may be applied to the shoe.

While I have illustrated `and described the preferred embodiment of my invention, it is to be understood that I do not limit myself to the precise constructions herein `disclosed and that various changes and modifications may be made within the scope of the invention as detined in the appended claims.

Having thus described my invention, what I claim as new, and desire to secure by United States Letters Patent l. A shoe comprising an outer sole having a shank portion and Ia heel, an inner sole and an upper with sides, a flexible sock lining having side portions with peripheral edges `secured to the sides of the upper land a central portion, said central and side portions being spaced from the inner sole `and the sides 'of the shoe and yoverlying said inner sole 'and sides in spaced relation, the shank portion and the inner isole having aligned openings for receiving molding material to be injected between said central and side portions of the iiexible lining and the inner sole yand sides of the shoe.

2. A shoe comprising an `outer sole having a shank portion and a heel, an inner sole Iand an upper with sides, a ilexible sock lining having side portions with peripheral edges Isecured to said sides `of the upper Iand a central portion spaced from the inner sole and the sides of the upper and overlying said inner sole and sides in spaced relation, and `a molding material in the space between said central and side portions of the flexible lining and the inner sole and sides of the shoe.
