COMPOSITION SHEET Filed NOV. 50, 1951 'Patented Nov. 2 4,v 1936 UNITED STATES PATENT CFF-ICE COMPOSITION SHEET Albert o. Fischer, chicago, 1u.

Apiilication November 3o. 1931, serial No. 577,963 16 claims.v (01.154-44) This invention relates to a composition sheet adapted for use as a surfacing or cushioning layer, and particularly pertains to a sheet of elastic character having distributed throughout its body numerous spaces or cells which may be left unfilled or filled with material differing in character from that of the body.

The invention consists in the features, combinations and compositions hereinafter described or claimed, for carrying out the above stated objects and such other objects as will hereinafter appear.

For a better understanding of the invention reference may b made to the accompanying drawing,- in which:

Fig. 1 is a perspective view of one preferred embodiment of the invention;

Fig. 2 is a view of another preferred embodiment, and l Fig. 3 is a plane view of still another preferred embodiment wherein the spaces are of irregular size and formation.

Numeral l designates a body of suitable material, such as rubber,' havinga series of spaces or apertures 2 formed therein, and preferably extending through the thickness of the body with intervening partition walls 3 between the spaces.

Where a maximum degree of resiliency is desired, the body may be of sponge rubber, or the exterior Wall may be of ordinary rubber with the partition walls between the spaces or apertures being of lsponge rubber. A sponge rubber construction is particularly p desirable where the product is to be used as'a cushioning means.

By forming and sponging a sheet in the form described, it is possible to produce a sponged product which is substantially as resistant to a compressing force as ordinary unsponged rubber made from the same-co1nposition would be. Accordingly, there is produced a'product having the general character of sponge rubber but yet is of the approximate degree of rigidity as ordinary unsponged rubber.

Sponge rubber is produced by introducing some substance within the rubber which generates a gas and expands the rubberinto a cellular form, at which time it is vulcanized.. The ltendency of the sponging ingredient is to expand transversely, rather than vertically, of the partition walls as less resistance is offered in this direction which, of course, is less than the vertical height of the partition Wall.. Accordingly, the resulting sheet is especially suitable for use where a greatersemilmosaic constructions where rigid pieces ofv mosaicmay be inserted within the spaces and separated by the resilient partition side walls. 'Ihe sheet is also suitable for many and varied other uses, such as, 'division members 'in ice trays,v 5 upholstery, thermal insulation, cushioning layers for floors, walls and the like. y

, In some of ,these uses, all or some of the spaces may advantageously be filled with hair matting 4 or such material for further adding to its resiliency, and one or both faces may be covered with surfacing layer 5 to enclose the spaces or the filling material inserted therein. y

While I have shown the preferred embodiments typifying my invention, and described them in detaiL/it will be understood that the invention is not limited thereby.l Various changes may be made in details of construction without departing from the spirit of the invention.

I claim: 1. A constructional strip comprising a body of sponge rubber provided with a vseries of perforations, filling material in at least some of the perforations, and reenforcing .strips of suitable material applied to face said perforated body. 25 A 2. A composition sheet comprising a resilient body provided with a series .o f perforations extending transversely .thereof 'and separated by sponge rubber partition walls, and a facing layer applied to surface at least one side of the perforated body.

f 3. A composition sheet comprising av resilient body provided with a series of perforations extending transversely thereof and separated by sponge rubber partition walls, filling mater-ialginserted within the perforations, and a facing layer applied to surface at least one side of the per- .forated.b0dy.

4. An article of manufacture comprising a sponge rubber cellular structure and a brous illler in atleast some of thecells of the structure.

5. An article of manufacture comprising a sponge rubber body having a number ofperforations extending substantially therethrough. and a brous filler in at least some of the perforations.

6. As a new article of manufactura-a reticulated sponge rubber sheet, the reticulated surface being formed by perforations extending through the sheet.

1'7. A thermal insulating unit comprising a multiple structure including alternate perforate and imperforate plies bonded together providing dead air cells Within the unit, and subdivided insulatconstruction a perforated sheet of sponge rubber and an outer wall of unsponged rubber closing one side of at least some of the perforations.

11. A resilient sheet comprising a resilient body portion provided with a series of deep cavities therein extending transversely thereof and separated by sponged rubber partition Walls, and a facing portionl extending along one side of the body portion and closing the cavities therein at one end.

12. A resilient sheet comprising a resilient body portion provided with a series of deep cavities therein extending transversely thereof and separa'ted by sponged rubber partition walls, a facing portion extending along one side of the body portion and closing the cavities therein at one end, and filling material inserted within said cavities.

13. A resilient-sheet comprising a resilient body portion provided with a series of deep cavities therein extending transversely thereof and separated by sponged rubber partition Walls, and a accresce facing portion extending along one side of the body portion and closing the cavities therein at one end; said cavities being several times as large in every dimension as the thickness of said partition walls whereby said resilient sheet is adapted to serve as a muticelled container.

14. A composition sheet comprising a resilient I body provided with a series of perforations extending transversely thereof and separated by sponge rubber partition walls, and a facing layer applied to surface at least one side of the perforated body, said cavities being several times as large in every dimension as the thickness of said partition walls whereby said resilient sheet is adapted to serve as a multicelled container.

15. An article of manufacture comprising a series of partition walls intersecting one another and at right angles to a common plane, said partition Walls being of sponged rubber, and an end wall of unsponged rubber; said intersecting partition Walls forming spaces therebetween which are several times as large in every dimension as the thickness of said partition walls whereby said article is adapted to serve as a multicelled container.

16. An article of manufacture comprising a series of partition walls intersecting one another and all lying at right angles to a common plane, said partition Walls being of sponged rubber and an end wall of unsponged rubber; said partition Walls being irregular in direction of extent ands spacing to form irregularly shaped spaces therebetween.
