To all whom itmag/ concern:

Be it-known that I, GEORGE PRIFOLD, a citizen of the United States, residing in Linwood, county of Delaware, and State of '5 Pennsylvania, -have invented new and useful .Improvements in "Waterproof Floor- Coverings, of which the following is a specification.

This invention relates to improvements in 10 flexible water-proof coverings composed of felt particularly, and has for its object the production. ofa felt covering for floors. which shall serve as a substitute for soealled linoleum or oil-cloth and the like, and.

which is extremely cheap yetresistantto the ordinary wear and tear to which floorcov-` erings are ordinarily subjected.

My investigationsand lexperiments have led to the discovery that a covering of' the '2 0 above nature suitable for application to pitch-impregnated felt can be obtained `by I applying to a foundation of so-called woolY felt saturated with'a suitablepitchy waterproof composition, as for example asphalt, J a priming coat consistingof a colloidal, or-

ganic -glutinous material preferably soluble casein, which is combined with an inorganic, relatively non-absorbent, inert filler such'as pulverized shale, or other minerals or mate- .305 rials which are relatively hard and nonporous and of an aluminiferous nature. To

a felt primed with the foregoing mixture is applied a color or finish coat of 'a paint or a varnish andthis when dried is preferablyi 3 5 printed in the usual manner employed for printing linoleum or oil-cloth to produce any desired pattern or color eifect thereon.

The preferred composition-which I ein-,f ploy, although obviously various vcomposi- 40 tions may lbe employed without, departlng.

from the invention set `forth in' the accompanying claims, consists of a solution of one pound of soluble casein, suchfor exam le asis known in'the ..trade as -Shac -ae G1ue.in six pounds oliwater. `This solution is allowed Ato. stand first i'n the cold without heating fora half hour orhour and is .then heated to thoroughly dissolve in vso far as possible the said ls'olublejcasein. To

this mixture is then added six pounds of inely powderedl shale, such for example as Y is vknown in the trade as Talckene, this mixture having a composition of approximately the following -wlthout pigment, is applied thereover, for

example a mixture consisting ofv one'part This priming mixture is applied to the Water I 3. 65% Silica I 63.20%" Alumina 16. 04%

I eroxid of iron 10. 25% Llme v 1 0. 59% 'Magnesla Potash 2. 50%

Soda 0.65%

Oxid of manganese Trace linseed oil and two parts of gloss oil mixed l with a pigment such as French ocher if dev sired, and thinned suiiciehtly-with naphtha :to the proper consistency for convenienuapplication. A second coat consisting of one part linseed oil and two parts of varnish, to-

gether with any suitable pigment `such as 4 yellow ocher may be superposed upon thev l,

Iirst color coat if desired. Then as stated the surface is printed'or suitably impressed or embossed so as to produce any desired color effects or pattern thereon in imitation of oil-cloth or linoleum.

In the accompanying drawing, v.forming -part of thls specification, Figure 1 illustrates a cross section of my improved floor- -covermg showing the successive' layersl or st epsotmy process, andFig. 2 is a Vplan view ofthe-same. V v The` p'ortion`2 representsthe base or foun- Idation of felt, 3 thepriming coat, 4 the oill and varnish coatingyand the'decoratingv orjembossmg to give thef final ornamental ,fllllSlL- 'k+1-" f e Ihe :priming ooat'is not 'only adhesive' both to the foundation layer andto the color coating, but is alsoiresistant tothe pitch-like nnpregnating compositions of the felt and 'to the pils, and'alcoholiof a'nd 'other ingred'.. ents contained 11i-'the finish coating. Moreover,beca use of the presence of an inorganicv water-insoluble, non-absorbent ller, such yas'the pulverized 'shale,1the coating-ofpaint or.4 yarnish applied thereto is not only pre- Vented from being absorbed into the felt,d

' but is rendered much harder thaiis the case where a water soluble inorganic-salt is employed, since said water insolubl'eller acts yed-linoleum fabric, sincev the felt foundation I is suliciently elastic to permit'of the yielding impact of the paint Vor -varnish coat against the shoevof `thewearer or the tire of va vehicle, such as a truck or the'glilge, whichV may ,come in contact therewithin/the ordinary use within buildings and the like.

. The term pitchy or pitch-like as employed in the claims includes pitchy materials genericall including pitch obtained by the disti lation of turpentine, bi-

tuinen or asphalt, as well as `petroleum pitches, coal tar Apitches o'like materials treated to impart' pitch-like properties.

^ thereto.

This invention is. distinguished from the v invention set forth in the patent to J. Smith,

No. 1,008,296 of November 7, 1911 for water,-

proof Hoor cove'ring, assigned to the Barrett' Manufacturing Company, the assignee of. this applicatlon', in that the Smith inventionv comprises the employment of an inorganic v colloidal glutinous material Ias one of the'es- 35 sential elementslof the composition.

v My invention` on the other hand does not Vinclude the use of such a composition and,

the` same is herebyl disclaimed, but itdoes specifically include the use of a sizingfcoating of water-soluble organic glutinousmaterial in conjunction with a water-insoluble mineral ller and the otherl elements vset forth in theclaims appended hereto.

1. A-water-proof covering for'floors-and the like, .comprising a so-called wool felt foundation impregnated 'with a water-proofof said foundation and the ingredients of ing composition, of a pitch-like nature, a coating of sizing superficially applied thereto, said sizing including a water soluble colloidal organic albuminous material and a pulverized shale min/eral `filler and-a nish coating containing paint -or varnish superposed upon said sizing coating, said sizing coating resistant to the impregnating composition said finish coating.

eing adhesive to both said. foundation and said finish coating, and being also 2. A water-proof covering for iioors and the like, comprising asoluble wool felt foun composition, of a pitch-like nature, a coating of sizing superficially appliedv thereto,

dation impregnated with a water-proofing i said sizing including a water-soluble colloidal organic albuminous ,material and a relatively non-porous pulverulent mineral iller'and1a inishcoating containing paint or varnish superposed upon said sizing coating, said sizing coating being adhesive to both said foundation and said finish coatnating composition of said foundationJ and the ingredients of saidJinish coating.

3. A waterproof covering for floors and the likecom`pr ising a soluble wool felt. foundation impregnated with a water-proofing composition,.of a pitch-like nature, a coating of sizing supercially applied thereto,

- said sizing including a casein material and a 4relatively lnon-porous pulverulent mineral `filler and a finish coating containing paint ,-or varnish superposed upon said sizlng coating, said sizing coating being adheslve to ing, .and beingalso'resistan't to the impregboth said foundation and said finish coating; and being also resistant to the impregnating compositlon of said foundation and the in` 'gredients of said finish coating.

In Witness whereof, IA havehereunto set vmy hand at Linwood, aforesaid, this 12 dayt Having thus descrlbed my invention, whatl Y I claim and desire to secure by Letters Patof February,` 1913. D I
