SHOE wrm cAvITY CONTAINING IMPRINT Filed April 18, 196s United States Patent O 3,169,326 SHE WITH CAVITY CNTAYENG lili/@RENT Matteo Butera, 4 Broadway, Lynbrook, N.Y. Filed Apr. 18, i963, Ser. No. 273,909 1 Claim. (Ci. S56- 2.5)
This invention relates to a molded shoe such as are custom made to tit an individuals feet and more particularly to an improvement in custom molded shoes wherein a sponge rubber sole element is retained peripherally by a semi-rigid cavity containing element.
A conventional practice in the shoe art is to apply a sponge rubber sheeting or pad as the top element of the insole and against which the foot of the wearer rests.
The Weight of the wearer on the sponge rubber pad squashes it, causing a lateral movement of the material. In due time, the sponge rubber pad loses its resilience or rebound qualities and for all practical purposes functions no longer as sponge rubber.
According to this invention, the sponge rubber pad is retained in captive relationship in a molded cavity of a relatively dexible composition.
It is an object of this invention to provide a sponge rubber foot engaging pad adapted to retain substantially permanent resiliency.
It is another object to provide a shoe having a sponge rubber sole pad retained permanently in captive relationship in a flexible sole.
It is a further object to provide a shoe having comfortable resiliency throughout the life of the shoe.
These and other objects of this invention will become apparent upon reaching the following descriptive disclosure taken in conjunction with the accompanying drawing of an illustrative embodiment in which:
FIG. 1 is a side elevation view of the shoe,
FIG. 2 is a longitudinal section view of the shoe showing the construction thereof, and
FIG. 3 is a section view taken on line 3 3 of FIG. l.
Turning to the drawing, the shoe of this invention is constructed by first making separate plaster casts of the customers two feet.
Next, the plaster cast is covered with suitable stocking material and two ply monks cloth 11 is secured thereto by conventional all purpose latex cement. Next a suitable cord of cotton or the like 12 is suitably located substantially toe high peripherally about the cast and adhered to the monks cloth by use of said cement.
Next, suitably thick sponge rubber padding 13 made of synthetic or natural rubber, is cut to the shape of the sole and its peripheral edges are tapered by means of a sharp knife.
The shaped sponge rubber pad is then adhered to the monks cloth by means of said cement and the edges thereof are made to engage said cord 12 and adhere thereto by means of said cement.
Next, a single ply monks cloth 14 is adhered to the outer surface of the sponge pad also by means of said cement.
cork or Wood flour is mixed with a conventional solvent containing latex composition and the mixture is then applied to the single ply monks cloth by means ot a spatula to form a cavitated element which upon drying is ilexible and adhesively secured to said monks cloth. Thus the shaped sole sponge pad is captively disposed in a cavitated exible sole element 15 of relatively rigid composition. Thus the combination of sole 13 and composition elernent 15 is novel and provides sponge resiliency in the shape retaining ilexible cavity containing element 15.
Next, a suitably wedge shaped heel element 16 cut from suitable relatively rigid sheet rubber is secured by said cement to said cavity element i5. Next a heel textile fabric 1S is secured about the theel by means of said cement. Then a lining of tine quality leather 19 is adhesively secured about the upper exposed area of the shoe by means of said cement. And lastly a suitable wearing sole 2t) of exteriorly corrugated rubber sheet is secured to the bottom of the shoe by said cement.
The molded shoe is then removed from the plaster cast by breaking the cast with suitable blows of a hammer.
Such a shoe is comfortable throughout its life since the sponge rubber insole 1 3 is fenced in and united to a resilient boat-like element 15.
This invention is disclosed by a specific embodiment illustrating the novel concept, which concept is oi' generic scope as claimed herein.
A custom made shoe comprising a first layer cloth insole having a foot shaped toe high cavity having a base portion therein; a flexible cord disposed peripherally about said insole and adhesively secured thereto; a second sponge rubber insole tapered at its edge secured adhesively to said cloth insole with .the tapered edge engaging said cord; a third insole layer of cloth secured adhesively to said rubber insole; a ilexible latex composition containing cork ller adhesively disposed onto said third layer of cloth; a wedge shaped flexible rubber heel adhesively secured to said flexible latex composition; exterior lining means adhesively secured to said insoles to form the rupper portion of said shoe and a lrubber wearing exterior sole adhesively secured to said latex composition at the front ofthe shoe and to said heel.
