y Specification of Letters Patent.

Patented Mar.. 24, 1914.

Application filed Noyember 16, 1912. Serial No. 731,786.

To 61N who-m 'it may concern.'

Be it known that.' I, J oHN E. MEER, a citizen of the lnited States of America, residing at N ew York city, county and State of New York, have invented certa-in new and useful Improvement-s in Vater-Tight, Sanitary Floors for Cars and Similar Structures, of which the following is a specification.

My invention relates to built up structures suitable for serving as surfacing for floors and the like and comprises a tough, water tight composite structure particularly adapted to serve as a flc-orcovering for refrigerator, pre-duce, dairy, beef, express, or passenger cars, etc., which would otherwise tend to rot rapidly from the effects of accumulated moisture.

The best. form of construction embodying my invention at present known to me is shown in the accompanying sheet. of drawing, in which,

yFigure 1 is a detail cross section through a part of the floor and one side of a. car provided with my improved floor covering. F ig. 2 is an enlarged detail cross section of said floor covering, and Fig. 3 is a diagram in plan showing` the expansion joints.

Throughout the drawings like reference characters indicate like parts.

l is a sill, 2 the top floor board, and 3 the inner side lining of a car, and 4 represents one of the holsters supporting same. As shown` the lowest course of the'inner lining 3, of plank is removed, and the lower edge of the lining undercutas at 5. -Under this are inserted and securely fastened courses of flexible fabric and asbestos or other insulating felts, as well as the waterproofing compound which covers the lower portion of the walls and stretches across the floor of the car, forming a partially flexible waterproof fabric 6. This floor coveringr 6 is built up of asphalt or bituminous mastic. layers of textile fabric, asbestos or other saturated felts and a skeleton metallic reinforcement such as expanded metal or other suitable'material, to produce a. hard, tough, waterproof and water tight sheet that will not crack or leak under the severest conditions of use.

Preferably, as shown in Fig. 2,' the structure is built up of a layer 7, of waterproofing cement, usually Trinidad asphalt or bituminous product, a sheet 8 of asbestos or other felt, saturated if desired with asphalt or other bituminous composition, another layer of the same cement 9, a layer of textile fabric 10 such as burlap which may be saturated with a bituminous compound, another layer 11 of cement and another layer l2of the textile material, followed by a layer 18A Asand which produces a hard surface on which racks may be laid without indenting it. Preferablyl insert in the layer of mastic 15, one or more strips 16 of bitumen of a consistence different from that of the mastic, and much more elastic. Preferably I arrange these lengthwise and crcsswise of the floor, as shown in the diagram, F ig. 3, and make them tapering in cross section, as shown in Figs. l and 2. These form -expansion joints with the layer of mastic and permit it to twist with the twisting of the car floor when running over an uneven track, and also permit the mastic to expand or contract slightly without cracking. The structure so produced is tough and will not crack with the twisting of the car body. Water tight and protects the sills and stringers of the car beneath it from the rotting effects of water produced by melting ice, etc. It has a hard finished surface which can be swept and scoured, and has the sanitary curve at the corners so that no filth can escape the cleansing action when the hose is turned on for washing out the car and the broom or scrubbing brush is plied.

Having, therefore, described my invention, I claim: f

1. A hard, but flexible waterproof covering for floors of railroad cars and the like comprising in combination a bottom layer of cement, a top layer of hard vmastic containing a metal reinforcement embedded therein, and an intermediate layer of fibrous fabric saturated with bituminous .material 2. A floor covering for railroad cars and the like comprising in combination a bottom layer of bituminous ce1nent.'a top layer of hard mastic, with strips of elastic bitumen It is` yinset therein, and an intermediate layer of panels, l:ind an intermediate layer comprisfabric saturated-With bituminous material. ing asbes'tos fabric saturated with bitumi- 1U 3, A floor covering for railroad cars and nous materials.

the like comprising in combination a bottom 5 layer of bituminous cement, a top layer composed of panels of hard mastic with a skele- Wvitnesses: ton metal reinforcement 'embedded therein H. SWARDELL, and strips of elasticbitumen between said GEORGE A. NicoL.
