quently sponged in order to provide a mass of.
cellular structure having a high degree of elasticity and flexibility. Strips formed from the sponged material and used in load sustainin structures are ordinarily suitable only in con- Junction with other materials of more rigid character,- the more rigid materials being exposed directly to the loads and the sponged material being indirectly exposed, such as being laid underneath surfacing material to provide a cushioning layer.
The aim of this invention is to provide a load sustaining slab of the general character of a sponged composition material, but with the sponged structure such that the slab may be of substantial rigidity vertically.
For a better understanding of the invention reference may be made to the accompanying drawing, in which: a
Fig. l is a perspective view position strip;
Fig; 2 is a perspective view of the sponged composition strip, or a strip cut therefrom in edgewise position; and
of a sponged com- -Fig. 3 is a perspective view of several of the .strips juxtaposed and arranged end to end with Numeral 2 designates acomposition sheet of- .material, such as rubber, which is sponged upon vulcanization by incorporating therein some ex-- pending or gas forming ingredient. ..When thesheet is vulcanized between the platens of a vulcanizing press, the resistance appears to be greater vertically than horizontally, causing the cells .3 to bulge out into more or less-elliptical form with the walls of the ellipses extending substantially in a horizontal direction. Moreover, the size of the ellipses is greater at the core of the. strip, progressively decreasing in size towards and merging in non-cellular or solid covering at the exposed surfaces of the strip. Due to theformation and arrangement of the cells,

the rigidity of the strip is greater horizontally than it is vertically.
In view of this peculiar structure of strip I have'found that it is in edgewise position especially advantageous for certain uses where a higher degree of vertical rigidity is re- [normal it sponge'd' quired than could be obtained by an ordinary sponged sheet. In chair cushions, typewriter padsQcarpet pads, for example, the strips may be laid in edgewise position and be sufficiently rigid, yet be sumciently resilient to provide suitable cushioning. The strips may be laid with their edges directly exposed to form the load receiving surface or they may be indirectly exposed by being laid beneath a surfacing layer.
Several of the strips may be advantageously 1o,
juxtaposed in face to face. relation and cemented together by a suitable adhesive or. cemented to an intervening sheet 4, such as paper, felt, muslin or other fibrous materials which may . details of construction, but that there may be various changes and variations without departing from the spirit of the invention.
I claim:
1. A cellular structural member constituting 3 a load-sustaining composite slab comprising strips of resilient sponged material wherein the cells are unbroken and elongated in shape juxbe bituminized or otherwise waterproofed if desired. Strips may be built up to any suitable length by arranging them in end to end ta'posed with the major axes of the cells normal to the load bearing. surface, and an intervening adhesive layer between said strips.
2. A cellular structural member constituting a load-sustaining composite slab comprising strips 'or resilient sponged material wherein the cells 40 are unbroken and elongated in shape juxtaposed with the major axes of the cells normal to the load bearing surface, and an intervening layer of fibrous material united to said strips.
3. A cellular structural member constituting a load-sustaining cushion strip comprising sponged rubber composition strips wherein the cells are unbroken and elongated in shape and a fibrous *layer/interposeii between the strips, the sponge rubber strips-having the major axes of their cells to the load bearing surface.
4. A cellular structural member constituting a load sustaining cushion slab comprising a pinrality "of stripsv of resilient sponged material havingthe cells thereof contiguous to one another and individually sealed, and an-intervem ing layer of a fibrous material adhered to each of said strips and extending in a plane substantially normal to the load-bearing surface.
5. A structural member constituting a load sustaining cushion comprising a plurality of relatively narrow strips of resilient sponged material in side by side relationship and an intervening layer of fibrous material between each pair of adjacent strips adhered to each of said strips and extending in a plane substantially normal to the load-bearing surface, said fibrous material reinforcing the cushion in its load sustaining capacity.
6. A structural member constituting a load sustaining cushion comprising a plurality of relatively narrow strips of resilient sponged material in side by side relationship and an intervening layer of fibrous material between each pair of adjacent strips adhered to each of said strips and extending. in a plane substantially normal to the load-bearing surface, said fibrous material reinforcing the cushion in its load sustaining capacity, said sponged strips being relatively dense adjacent to said fibrous material whereby the dense portions of the strips and the fibrous material mutually contribute to strengthen said cushion in its load sustaining capacity.
8. A structural member constituting a load sustaining cushion comprising adjacently disposed strips of sponged rubber separated by sheets of fibrous material, each of which sheets is adhered to faces of adjacent strips of sponged rub her and extends in a plane substantially normal to the load-bearing surface.
9. A structural member constituting a load sustaining cushion comprising adjacently dissheets of fibrous material, eachof which sheets is adhered to facesof adjacent strips of sponged rubber and extends in a plane substantially normal to the load-bearing surface, said strips being relatively dense adjacent said sheets whereby said dense areas and said sheets cooperate to strengthen said cushion in its load sustaining capacity.
10. A structural member constituting a load sustaining cushion comprising 4 adjacently disposed strips of sponged rubber separated by sheets of fibrous materialyeach of which sheets is adhered to faces of adjacent strips of sponged rubber and extends in a plane substantially normal to the load-bearing surface, said strips having elongated cells therein which are elongated predominately in a direction substantially parallel to the planes of the sheets of fibrous material.
