SURFACE COVER'ING MATERIAL Filed April 20, I929 A preferred composition is as follows l alzentecl 1 mg. 23, 1932 UNILT'ED STATES-PATENT OFFICE 311111. R.

Serial 110.356,?04.

. This invention relates tosurfacecovering material and is particularly adapted for use on the running boards of automobiles, al-

though it has numerous other applications.

BL Auto mat material as used on the running boards "of automobiles must withstand consld- "erabl'e wearit mustbe water-proof, and

- must be resistant to sunlight and rain, as Well 1 as to wide extremes of temperature. 1

Linoleum compositions, particularly those having as a major ingredientpitch such as 7 1 application of S. H. Hartman, Serial No.

304,613, filed Sept. 7, 1928. Such material is preferably calendered onto a; water-proof Humphreys' paper backing, as described in ,Patent No. 1,129,571.

Parts Linoleum cement I 90 Ground cork above proportions are by weight. It is desirable to have a black composition as this permits of using linoleum scrap of any color. This composition, because of its high pitch content,is affected but'little if any, by ultravioletlight. There is therefore no tendency toward disintegration from direct sunlight,

. as is the case in ordinary linoleum mixtures.

v The above mix is also highly water resistant and will withstand considerable scufilng and abrasion. It is very little affected by expansion and contraction and bonds readilyfwith q the paper base. I Y

Automob ile manufacturers require .a ribbed surface for their auto mat material, not only because of its improved appearance, but

7 also because it gives a desirable tread surface. .50 In calendering mixtures suitable for auto e 100; Linoleumscrap 450't0 500 To the above may be added 12 parts of carl. l All fth' bon black to Insure a b 10k CO or 0 so. as to entirelyhide the pits. Preferablyit mat use, there is a tendency for the bottom of the grooves between ribsto roughen. he ribbed calender roll is-set to slip onjthe face of the goods so as to give something ofa burnishing action and thus secure a smooths face, but while this result is obtained on-the show depressions somewhat resembling pock marks. This destroys the appearance of the entire product and because of the roughened surface, it is likely to decrease the life of the material; .Water lying on the running board i of the car can get into the pits or depressions of the roughened'groovebottoms and uponv freezing cause I damage which, although slight, will, if repeated a sufhcient number of times,.ultimately affect the life and'ap pearance of the mat. 1,

I' provide for placing a paint-like mate rial in the corrugationsso as to fill the pits therein andprovide a smooth surface. The

paint-like material employed is preferably one which has a solvent action on the binder of the body material. When the filler material has such solventaction this fact, coupled with the roughness of the grooves, results in the filler material being firmly keyed to the body." In fact, flexing of the material' shows that the paint-like material very firmly adheres .to the bottoms of the grooves. 'The-pain't employed is preferably opaque is not of'suflicient thickness to entirely fill the grooves. The ribs therefore take all of the wear and the paint is not subjected to scufling. It Will therefore'preserveits survribs themselves, the grooves therebetween face appearance indefinitely. By using'a' paint or a contrasting color, very desirable efl'ects may be obtained.
