3 Claims. 1

This invention relates to railroad refrigerator cars having hatches in the roof thereof through which refrigerant containers, positioned immediately below the roof, but spaced slightly therefrom for air circulation therebetween, are serviced, said containers having openings in the top surface thereof registering with the hatch openings in the car roof, and is an improvement over the construction shown in Bonsall Patent No. 2,136,999 of November 15, 1938.

The invention more specifically relates to such cars having refrigerant containers of the solid type for holding brine or water ice as the refrigerating medium, and which containers, therefore, must have means to prevent service movements of the car from causing the liquid in said containers to surge out through the filling opening into said space thereabove and thence into the car.

An object of the invention is to so associate the container with the roof and hatch plug so that when the plug is opened for ventilation air coming into the car through the hatch may circulate about the container and enter the lading compartment of the car.

Another object of the invention is to provide means between the refrigerant container and the car roof so as to materially retard, if not prevent, surging of the liquid therein out through the filling opening.

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

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

Figure 1 is a vertical section of part of a railway car showing the invention.

Figure 2 is a section on line 2-2 of Figure 1.

In the drawings, i represents the side wall of a 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 our present invention.

A hatch opening 3 is formed in the roof 2, extending therethrough and is provided with a hatch frame as is common. Immediately below the roof, but spaced slightly therefrom, is a refrlgerant container 4, having an opening 5 in the upper surface thereof which registers with the hatch opening 3. The container 4 is spaced from the roof 2 to provide an air circulating and air cooling space It, and also to provide a path for ventilating air to the interior of the car when the hatch plug is removed or raised for ventilate ing purposes.

As is common in refrigerator cars of this type, a substantially horizontally disposed drip pan (or ceiling) 1 is installed below the refrigerant container 4 and spaced slightly therefrom to form an air cooling space H therebetween. This drip pan extends from approximately the longitudinal center of the car l9 where it is provided with an upwardly extending baflle 8. Space l1 communicates with flue 9 associated with said wall I. A path for circulating air, when the car is under ventilation, is thus provided around the container to and downwardly through the interior of the car, as indicated by the arrows.

Figures 1 and 2 show the refrigerant containers being formed of separable parts. The top of the container is made separate from the remainder of the container and the downwardly and outwardly inclined collar 30 welded or otherwise 86- cured to an upstanding flange 3| about the perimeter of the filling opening '32. The hatch frame 33 projects downwardly into the collar so that the lower margin of said hatch frame and collar 30 cooperate to retard splashing of liquid in the container into the space l6 between the container and the roof.

The accompanying drawing illustrates the preferred form of the invention, though it is to be understood that the invention is not limited to the exact details of construction shown and described, as it is obvious that various modifications thereof, within the scope of the claims, will occur to persons skilled in the art.

This is a division of our co-pending application Serial No. 574,790, filed January 26, 1945, now Patent No. 2,453,294, granted November 9, 1948.

We claim:

1. In a refrigerator car having a hatch opening in the roof thereof and a hatch frame therein extending below said roof container disposed below and spaced from said roof to provide air circulating space therebetween and having a filling opening therein registering with said hatch opening, and means to prevent liquid within the container from surging out of the filling opening into said space during service movements of the car without preventing air communication between said hatch opening and said air circulating space, said means comprising an upstanding flange around said filling opening and a separate collar secured to said flange in spaced relation to said frame and having a part extending into the container to retard surging of liquid therein through said filling opening, said flange and collar overlapping said hatch frame.

2. In a refrigerator car having a hatch opening frame depending below the roof of the car, a refrigerant container spaced below the roof of the car so as to provide a space between the roof and the container hatch opening and the interior of the car for ventilation, said container having a filling openlng registering with the hatch opening, said frame extending through and below the filling opening, and a collar secured to the container at the edge of the filling opening, said collar having a substantially vertical portion projecting into the container and a, horizontal portion spaced from said frame, whereby surging liquid in the container is bafiled by the lower part of the frame and the vertical portion of the collar without preventing ventilating air from the hatch opening enterin the space between the roof and the container.

3. In a refrigerator car having a hatch opening which communicates with the in the roof thereof, a refrigerant container disposed below and spaced from said roof to provide an air circulating space therebetween, a filling opening in said container registering with said hatch opening, and a collar formed at the edges of said filling opening and extending thereabove and within said container to retard surging of liquid through said opening, and a, hatch frame within saidhatch opening extending through said space and within said collar.
