RAILWAY ROLLING-STOCK.

SPECIFICATION forming part of Letters Patent No. 635,799, dated October 31, 1899.

Application tiled March 9, 1898. Serial No. 673,166. (No model.)

To all whom t may concern:

Be it known that I, DANIEL MCOOOL, a citi zen of the United States, residing at the city of St. Louis, State of Missouri, have invented certain new and useful Improvements in Railway Rolling-Stock, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompany# ing drawings, forming part of this speciication, in which- Figure l is a cross-sectional view through a car embodying my invention. Fig. 2 is a detail View of a portion of a roof, showing the manner of applying my invention thereto. Fig. 3 is an enlarged sectional view through a portion of a roof secured in position on a car, and Fig. 4 is a detail view of the cementitious substance used in my improved car construction.

This invention relates to a new and useful improvement in railway rolling-stock, and particularly to the construction of what are known as box-cars,7 the object being to arrange a cementitious substance therein to prevent the entrance of rain, dust, cinders, rbc., into the car through the sheathing-boards of the roof and also to provide a waterproof trough or flooring for the car when it is used .as a refrigerator-car.

W'ith these objects in view the invention consists in the arrangement, construction, and combination of the several parts, all as will hereinafter be described and afterward pointed out in the claims.

In the drawings I have shown in Fig. l a cross-sectional view of what is known as a refrigerator-car, while in Figs. 2 and 3 I have shown an ordinary box'car.

In the drawings, A indicates the side wall of a car, which, as shown in Fig. l, is provided with paper or felt or other non-heatconducting material and in some constructions dead or live air spaces. The side wall of the car, however, has little to do with my invention, as it consists, so far as the ilooring of the car is concerned, in the arrangement of a cementitious substance B between the upper floor proper and the subfloor. These floors are preferably inclined to conduct the drippings to a central trough, whence the water is led to the exterior through a pipe O. In applying this substance in building the car I lay the subiioor D in position and then arrange the cementitious substance B thereon. This substance, as shown, extends upwardly any desired distance against the inside wall A. By the provision of this cementitious substance B in the flooring and up the side walls of the car the sills and lower iiooring are protected from moisture, and consequently preserved. Such a iioor is of great value also in cattle-cars, where the moisture will penetrate into the lnortised joints of the sills and rot the same.

The cementitious substance above referred to preferably consists of burlap treated with a lnagnesian cement, said burlap being laid in position while in a plastic state and the top flooringplaced in position thereon while the burlap is still wet, the burlap, with its cement, acting as a binder between the upper and lower floors. The magnesian cement, forming the composition with which the burlapis treated, is made by combining magnesium oxid and magnesium chlorid, the two making a bath in which the burlap is immersed, said burlap forming a fibrous filler for the cement.

The roof is also provided with a cementitions filler and binder, (marked E in the drawings.) The subroof or inner sheathing F is preferably arranged longitudinally the car, of tongue-and-grooved material, which is nailed to the carlines, the upper roof-sheathing G being arranged transversely the car. The burlap, treated as above described, is laid across the lower sheathing F and down along the side walls of the car, as at e, after which the upper sheathing G is placed in position and the crown-mold or faciaH arranged to protect the depending edges e. The upper sheathing G preferably extends some distance beyond the crown-mold II to conduct off the water.

As shown in Fig. 4, the cementitious substance B consists of two-ply burlap treated as above described; but it is obvious that one or more plies could be .used with equal success.

I-Iaving thus described my invention, what IOO I claim, and desire to secure by Letters Patent, is-

l. In a car the combination of an inner sheathing of boards, an outer sheathing of boards, a wall at an angle to said sheathings and comprising an innerand an outer sheathing, and a continuous layer of cementitious material between and uniting said inner and outer board sheathings and extending between the sheathings of said wall, substantially as set forth.

2. In a car, the combination with a board suboor, a board iioor proper, and a side wall comprising an inner and outer sheathing, of a continuous layer of cementitious material between said suboor and floor proper and extending up between .said inner and outer side wall-sheathin gs, substantially as set forth.

In a car, the combination with a floor comprising an inner and outer sheathing, and a side wall comprising an inner and outer sheathing, of a continuous layer of cementitious material between said inner and outer ioor-slieatliings and extending up between said inner and outer side wall-sheathings,substantiall y as described.

4. In a car, the combination of a floor comprising an inner and outer board layer, side Walls comprising an inner and outer sheathing, a continuous layer of cementitious material between and uniting the floor layers and extending up between and secured to the inner wall-sheathing, and a root comprising an inner sheathing, an outer sheathing and a continuous cementitious layer between and uniting said layers and ext-ending down the outer face of the side walls, substantially as described.

5. In a car, the combination with a floor proper and its subfloor, of a cementitious material arranged therebetween, of side walls A and A', said cementitious material continuing up the side walls, a centrally-arranged trough, and a drip-pipe C extending from said trough, substantially as described.

6. In a car, the combination with the inner and outer sheathing-boards, of a cementitious substance arranged between said sheathingboards, said cementitious substance being applied in position while in a moist or plastic state and penetrating the pores of the wood to make the same waterproof, after which said cementitious material hardens, continuing some distance down the side and end walls of the car, substantially as described.

7. In a car, the combination with the inner and outersheathing-boards, of a cementitious material arranged between said sheathingboards,said cementitious material continuing some distance down the side and end walls of the car, and a crown-mold for protecting the cementitious material at the sides and ends of the car, substantially as described.

S. In a car, the combination with the nclined floor proper and its subfloor, of side walls A and A', said walls A' resting upon the fioor proper,a cementitious material arranged between said iloor proper and its subfloor, the ends of said cementitious substance continuing upwardly and being secured to said walls A', a roof formed with an inner sheathing F and an outer sheathing G, a cementitions material arranged between said sheathings and continuing over, or extending down along, the face of the walls A, and a crownmold II arranged outside of said cementitious material to hold the same in place, substantially as described.

In testimony whereof I hereunto a'Iix my signature, in the presence of two witnesses, this lst da;7 of March, 1898.

DANIEL MCCOOL.
