The principal object, thereforerof my in-' v vention is to provide. a surface structure for railway car flOOIS aIICl similar flooring which will be strong and, tough andwhich will efiiectivelv resist the'strains and stresses the' interest lof. clearness Figx 1- is a. broken towhich such platformsare subjected thus remaining intact, formingpractically a-hermetical seal between the freight space and the lowermost constructionoftheafloon of the, 'car.

$1118: of a railway car, B the s1des,.C the 1Tb! iwhich consists eat a strong; elastic composite structure and particularly designed to prereaching the heat insulation which is provided inirefrigerator cars and thereby pres vent the said insulation from rotting. or.

.ventionally in horizontal cross section, the floor covering beingv broken, away.- at the cornensto show the construction underneath.

( r In Fig. thegratingwhich is usually installed in the refrigerating sectionsis shown only-in cross section, this grating in, prac-. tice being duplicated at the other end. ofthe car. In the interest of clear-mess. however, the grating is notshown infFigs. 1, 2.;and

4, because; if illustrated, the grating which; is notva part of my nvent on wouldycover up the construction. pertaining to. the invention herein CllSClOSGd and claimed.

In the drawlng, A- represents the usual ner wall, D the heat insulation, E the stanchionsor posts, F the shoes for supporting the stanchio ns, G the supporting beams for the gratin'g'har-s H; I are the drainsincthe re-o rigerator ends otthecar-and Kthe flooring in the main body of the car, all of which are of the usual construction and conventionally shown and well understood by those skilled in this art.

1 In thedrawing, is a composition floor covering made preferably of a mixture of high grade asphalt and very fine sand, the said composition being laid on top of the flooring in the main body of the car and on the top of the insulation in the refrigerator ends of the car. This floor covering composition is preferably approximately 1 inch in thickness and it extends upwardly at the ends and sides of the car for a distance of approximately 3 inches.

In laying the surface flooring strips of ' wood 20 and 21, each being triangular in horizontal cross section, are secured on the insulation below the ice-boxes in the longi tudinal cornersbetween the insulation and the inner walls of the carby means of spikes 22 driven through the strips and into the lIlSLllEItlGll, the strips being positioned at a distance of about ..,-th of an inch in width from the side walls of the car. Similar strips and 31 run longitudinally of the car from ice-boa: bulkhead to ice box bulkhead. eXce t for the s aces necessar P Tl lar strips 30 and 31 and the inner walls of the car.

Across each end of the car a triangular strip of wood 35 is secured (one only being shown). This strip borders the end of the walls formed underneath thegrating of the ice-box. The composition isthen laid over the floor of the main body of the car and over the insulation underneath the ice-boxes at a thickness of approximately 1 inch, and it is, extended upwardly over the hypothenuse of the triangular strips 20, 21, 30 and 31 for a distance of 3 inches. but does not contact with the side walls and end corner strips 35 of the car, the open space between them being about inch in width. Each of these spaces or crevices is filled with a bituminous binder designated at 40, 41 and i 42, which binder, because of its resiliency.

will give when the parts of the car are caused I to vibrate to and from each other when the car is in motion and thus will always provide a'hermetical seal between the edges of the strips and the edges of the composition flooring and the sides and ends of the car. So also, in the spaces about Q, inch wide,

formed around the drains, a bituminous binder 43 and 44 is poured so that in the event of movement of the drains with respect I to the composition flooring, the bituminous binder will always remain intact and prevent crackage between the composition flooring and the drains. Also the bituminous binderfills the spaces 43, 44, 45, 46 and 47 formed between the edge of the composition flooring and the metal supports for the stanchion of the ice-box bulkheads, likewise to prevent crevices being formed therebetween, so that water and other matter will not ooze from the surface of the composition down to the flooring or the insulation. The widths of these spaces are about I inch.

At the junction of the side flanges of the composition formed entirely around the car,

layers o'fbituminous binder 50, 51 and 52 are placed, this being also of a resilient character so that at the corners where the strains and stresses are great the binder will not crack and will thus form a surface at the corners which will always remain intact,

thus preventing water from the melting ice and material from the freight which is tionat 200 gram at 32 degrees F. 18, the

specific gravity 1.01.

Referring more particularly to Figs. 1 and 5, the door openings are indicated at O, the sides of which are preferably lined with sheet metal and 71, the sills being reinforced by metal plates 72 and '78. Just in side of the door opening are placed metal plates 74 and 7 5 which extend the width of the door and project inside a short distance, as clearly shown, to protect the sloping edges 76 and 77 of the composition at the doors from undue wear occasioned by the trucks which are frequently used when loading or unloading thecar.

As changes of constructions could be made withinthe scope of myinvention, it is intended that all matter contained in the above description or shown in the accompanying drawings be interpreted as illustrative and not in a limiting sense.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is r 1. In a railway car, the combination of walls. a supporting floor, strips on said floor having one face slightly spacedfrom said walls, a hard, waterproof layer on said floor extending upwardly on said strips to provide a narrow space between the edge of said layer and said walls, and a resilient filler in said space between said walls and said strip and the adjacent edges of said layer. s

2. In-a railway car, the combination of walls, a supporting floor, strips of trianguwaterproof surface layer on said floor ex tending upwardly on said strips to provide a narrow space between the edge of said layer and said walls, and a bituminous binder in said space between said walls and said strip and the adjacent edges of said layer.

4; In a railway car, the combination of a hard, waterproof floor surface layer having upwardly inclined edge portions, a flat supporting surface for said layer inclined v slightly upwardly toward the walls of said car to support said upwardly inclined portions of said layer, and a resilient filler between and separating the walls of said car from the edges of said layer.

5.'In a railway car,'the combination of walls, a flat floor having its edge portions inclined upwardly, a hard, waterproof surface layer covering said floor and said upwardly inclined edge portions, and a resili-' surface layer from said i angle between the flat and the upwardly inclined portions.

7. In combination with a hard, water proof car floor covering comprising a body car floor covering comprising a body por-,

tion and an upwardly inclined side flanged portion, a bituminous binder covering the junction of said body and flanged portions, car walls, and a bituminous binder between and separating the edge of said floor covering from said walls. 9. In a refrigerator railway car, the combination of inner walls, heat insulating flooring, strips secured to said flooring and spaced from said inner walls, a hard, waterproof floor covering on said flooring and strips having its side edges spaced from said inner walls, and a bituminous binder in the space between said strips and walls and between said floor covering and walls to prevent the formation of cracks thereby preventing moisture on the floor covering from, reaching said flooring. 10. In a railway car, the combination of walls, a supporting flooring, a floor of asphalt and sand composition having its edges slightly spaced from the inner surface of saidiwalls, and a filling of resilient material impervious'to moisture in the space betwee said walls and floor.

11. In a car having a floor and stanchions extending downwardly and supported on said floor, a hard, waterproof surface layer on said floor and slightly spaced from said stanchions, and a bituminous binderfilling thespace between said floor and stanchions to provide aliquid-tight seal therebetween.
