Ill., a corporation of Delaware Application lVay 26,1950, Serial o. s claims. (Cl. s2- 17) This invention relates to railroad refrigerator cars having hatches in the roof thereof through which refrigerant containers, located adjacent the roof, but spaced slightly therebelow for air circulation therebetween, are serviced, said containers having openings in the top thereof registering with the hatch openings in the car roof.

The invention more specifically relates to such cars having containers for holding brine and water ice as the refrigerating medium.

The high speeds of modern freight trains induce a vigorous swaying action of the cars, and where the liquid is a b rine solution, a consequent surging of liquid in said containers.

It is often desirable to provide refrigerant containers with apertures so that when the car is in Ventilating service outside air may be admitted through the hatches, container and apertures into the interior of the car. Such apertured containers, however, must be so constructed that when in ordinary refrigerating service, the brine cannot splash through the apertures into the interior of the car, which construction of container is the principal object of the invention.

Another object of the invention is to provide said containers with a novel form of overow plug and down spout for draining the containers when necessary.

Other objects and advantages of the invention will appear in the following description thereof.

Referring now to the accompanying drawing forming part of this application and wherein like reference characters indicate like parts:

Figure l is a partial transverse section of a refrigerator car embodying the invention in its simplest form.

Figure 2 is a view similar to Figure l of a modified form of the invention.

In the drawings 1 represents the upper portion of the side wall of a railway refrigerator car and 2 the roof thereof, both of which it will be understood are of suitable insulated construction, the details of which may be omitted, since they form no part of my present invention. Roof sheet 3 extends across the car roof and has turndowned anges at the ends, one of which is shown at 4, which lap side sill 5, as is common. Spaced inwardly from flange 4 is formed a hatch opening 6 and roof sheet 3 is provided with upturned anges 7 about said opening. A hatch frame 8, which is in the form of a downwardly facing channel, overlaps the ange 7. A hatch box 9 is fitted within the hatch frame 8 and extends downwardly through the roof and terminates in a laterally turned ange 10 which rests upon a gasket 11 upon the upwardly bulged margins of opening 12 formed in the top sheet 13 of ice container 14. Opening 12 is concentric with the opening formed by hatch box 9 through which concentric openings container 14 may be serviced with ice or other refrigerating mediums. Container 14 comprises side walls 15, end walls, one of which is shown at 16, and bottom 17, which are integrally formed. The inner side wall 15 extends above the top of end walls 16 and is flanged inwardly, as at 18, whereas the outer side wall 15 is flanged inwardly and forms a seat for the outer side margin of top sheet 13. The inner side of top sheet 13 is flanged downwardly, as at 19, forming a false side wall which does not extend downwardly to bottom 17, leaving a space 20 therebetween. Bafiies 21 extend inwardly and downwardly toward each other in alternately spaced relations from walls 19 and 15 to retard surging of liquid from said container upwardly through the space between walls 19 and 15. When the ice lspace between walls' 19 and 15 into theV interior of the car; f To d rain said container when desired a drain spoutZS iszsecured tb the. lower outer corner of said container, said spout extending within. a funnelflik uppeir endx26 of downspout 27 extending downwardly through the oor of the car. An L-shaped section of pipe having a tapered end 28 extends within spout 25 and fits snugly therein to provide an effective seal when therein. Other end 29 of said pipe extends upwardly adjacent outer wall 15 terminating adjacent top sheet 13 and is provided with overflow openings 30. A V-shaped handle 31 is secured to the side of end 29, one leg of which handle projects toward opening 12 so that an operator may reach through hatchway 9 or opening 12, and grasp said handle 31, to remove or replace the pipe 28--29 from or to the drain spout. For greater convenience, a chain, a portion of which is shown at 32, is secured to said handle, a link of which may be hooked by an instrument inserted through the hatchway 9 and opening 12 and thereby removes the pipe 28-29 for draining the container. A yoke 33 extends around the pipe 28-29 with the free ends thereof pivoted in a bracket 34, which yoke holds the pipe 28-29 in position, and so that the vibration or swaying of the car would not shake the pipe loose thereby permitting the brine to drain out. This yoke must be swung up and over the pipe 28-29 before the latter can be removed. The tighter the pipe fits within spout 25 the farther the yoke will slide down in the V-notch' of the handle 31.

In the structure shown in Figure 2, the container 14 is formed with both side walls arranged for ventilation. The top sheet 35 is formed with the filling opening 12, as in Figure 1, and is hanged downwardly, as at 36 and 37, at both sides, forming false side walls, the lower edges of which are spaced from the bottom of the container. The bottom 38 extends beyondfalse side walls 36 and 37 and is flanged upwardly forming side walls 39 and 40 spaced from false side walls 36 and 37, and end walls, one of which is shown at 41. Walls 39-36 and 40-37 are provided with baffles 42 which extend downwardly and inwardly within the spaces between said walls and prevent surging of liquid upwardly therethrough when the container 14 is lled with brine.

I claim:

l. A refrigerant container for a railway refrigerator car, said container having a filling opening therein, said container having a top portion secured \-along three margins to three contiguous walls of said container and formed with a downturned false wall spaced from the other wall of said container, said false wall and said other wall having spaced baflles extending toward each other to retard surging of liquid within said container upwardly in the space between said other wall and false wall of said container.

2. A refrigerant container for a railway refrigerator car, said container having a filling opening therein, the top of said container provided with a downturned flange spaced inwardly from a side wall to form a false side wall spaced from said side wall, said false wall and said side wall having spaced baffles extending toward each other to retard surging of liquid within said container upwardly in the space between the side wall and false wall of said container.

3. A refrigerant container for a railway refrigerator car, said container comprising integrally formed spaced side and end walls and bottom, a top portion secured along three margins to one end and the sides of said container, extending to adjacent the other end wall, and formed into a false endwall spaced from said other end wall and said bottom, and spaced bafles extending overlappingly toward each other from said false end wall and said other end wall.
