REFRIGERATOR-OAR. d

To all whom it may concern:

Be it known that I, MADISON COOPER, of Minneapolis, in the county of Hennepin, State of Minnesota, have invented certain new and useful Improvements in Refri of which the following is a specification.

This invention relates to improvements in refrigerator cars, and the object of the inventlon is to provide arefrigerator car of simple and inex ensive construction in which a complete an uniform circulation of the air through the body of the car will be secured.

The invention consists. generally in the constructions and combinations, hereinafter described and particularly pointed out in'Ithe filaims. d3 f n t e accom' any' awin s, orming part of this specificat i o n; Figure l is a longitudinal vertical section of a refrigeratorcar embodying my invention. Fig. 2 is a transverse vertical section through the air cooling chamber and ice receptacle. Fig. 3 is a transverse section throu the car. Figs. 4 and '5 are etails. Fig. 5 being an enlarged cross section of plate 29.

In the drawings, 1 represents the bod ofthe car which may be of any preferred or usual construction. The walls of the car are preferably provided with suitable non-conducting material preventing the admission of heated air through the walls of the car. The car is preferably provided with a perforated false floor 3, arranged a short distance above the main floor 2 and preferably made in sections so as to be removed in order to permit the cleansing of the car, also to permit the car to be used for other purposes.

The sections may be made. so as to e removable from the car body or, as shown in Fi 3, each section may be hinged at 5 to the Weill of the car so as to be capable of being turned into a vertical position against the side wall of the car in which position the sections may be secured by an suitable means. Each section is provided below the perforated floor with a series of longitudinal strips 6 which form supports for the floor and also provide air ducts below the floor, permitting the free circulation of the air lengthwise of the car below the floor.

At each end of the car, I prefer to provide an air cooling chamber, preferably formed by a transverse partition 9 that extends across the car at a suitable distance from the end Specification of Letters Patent. Application filed May 2, 1908. Serial No. 155,290.

and partitions off a space at the end of the car. The partition 9 does not extend uite to the roof of the car nor to the bottom 0 the car althou h its lower end is below the level of the per orated floor 3. I prefer to. provide a ed section 11 at the lower edge of the cross partition 9, this section being capaermit access to the lower part of t e air coo ing chamber when it is desired to clean the same. Arranged within the air cooling chamber, preferably at each end of the car, is an ice bunker or receptacle 13. This receptacle is preferand is supported upon suitable bars 15 and 17. The ice rece tacle is open at the top and access ma e had th'ereto through a suitable door 19 w ich may be removed when desired for permitting g'the receptacle with ice. The ice receptacle is smaller than the air cooling chamber so that a clear space is left all around the ice receptacle between its Walls and the innerwall of the air cooling room. Surrounding the ice receptacle and between said recepe tacle and the walls of air cooling room, I refer to arrange the metallic plates 21. T ese plates are preferably ver-tically'arranged with, a space between each plate and the wall of a the air cooling room and with a space also between each late and the wire nett' forming the wal of the ice receptacle. There is, therefore, a clear space for the passage of air between each of these lates and the wall of the air cooling room an; another space between each plate and the ice rece tacle.

Arranged in the lower part of t e air cooling chamber, is a trough or gutter 23 extending transversely of the car and connecting with a waste pi e 25 provided'with a suitable trap 27 at its ower end. In order to conduct the water that drips from the ice rece tacle into this trough I inclined plates 29 and versely of the car body and are arranged to conduct the Water into said trough. These plates are preferably corrugated as shown in detail in F1 5, so as to prevent spattering of the water t at drips upon them. The water passes into the recesses formed by the corrugations and runnin down such recesses passes into the troug or gutter by which it 1s conducted to the waste pipe 25. The inclined plate 29, which is nearest the end of the car, is preferably of greater height than the plate 31 arranged between the tron h and the body of the car. This plate is near y prefer to provide t e 31 that extend. transthrou fiat solthat it'forms a continuation of the floor of the car. This leaves-ya free space for the assage of air from theair cooling room beow'the partition 9 and into the space below the perforated false floor 3 (see Fig. 4). This arrangement also permits drainin any water that may get onto the floor of t e car into the gutter 23, the floor 2 being inclined in opposite directions from the center of the car towards the ends. I also prefer to provide a transverse deflectin plate 33 arranged above the plate 31 and be ow the portion of the ice receptacle that is towards the body of the car. This late tends to deflect the water that dri' s om that side of the ice receptacle and to irect it into the gutter 23.

I also prefer to provide the car body with a perforated false ceiling 35, preferabl made in two sections, one at either side of t e door opening and the space above this false ceiling communicates with the air cooling room h the open space above the partition 9 (see ig. 1). The ceiling 36 above the false ceiling is preferably inclined so that the air space above the false ceiling increases in size towards the air cooling room thus permitting free passage of the air.

The operation of the apparatus is as follows: The ice bunkers or receptacles are su plied with ice through the door 19 and t e car being loaded and closed, the cold air flows down through the air cooling room and ice receptacle and asses into the space beneath the erforated alse floor 3. It travels along in t s space and rising through the erforations, travels upwards the car to t e false ceiling into the space above such ceiling and along in said space over the top of the artition 9 and enters the upper part of t e air cooling chamber. A circulation of air is thus obtained downward through the air coolin chamber. under the false floor, upwar through the erforations' in said floor, through the b0 y of the car, through the perforations inthe false ceiling, along the space above such ceiling and into the up er. part of the air cooling room. The ice' ein surrounded by a wire netting only, as t e air passes downward, along and through the ice receptacle, it is cooled by being brought in a direct contact with the ice. A portion of the air passes through the space between the plate 21 and the wall of the air coolin chamer and therefore in contact with suc 1 plate 21. A portion of the air also passes between said plate and the ice receptacle. As the ice becomes melted from absorption of heat, the water drips from the ice rece taele onto the

plates

33, 29 and 31, which argely increase the effective cooling surfaces, and is conducted into the trough or gutter 23 from which it passes through the waste pipe 25. This operation is continued at each end of the car so long as an ice remains in the ice bunkers or receptac es. By this means a rapid cooling of the air is obtained and a thorough and uniform circulation throu hout the body of the car. Any water or ot ier liquid that gets onto the floor of the car will pass into t e gutter and out through the drain pipe. The interior of the car can also be washed or flooded and the water will be carried off through the gutter.

I claim as my nvent1on:

1. The combination, in a refri erator car, with an air cooling room at eac end, of a main floor inclined in opposite directions from the center, a perforated false floor arran ed above said main floor, suitable gutters at t e ends of the main floor, a main ceiling inclined in op osite directions from the center towards t e ends of the car, and a perforated false ceiling arranged below said main ceiling, substantially as described.

2. The combination, in a refrigerator car provided with an air cooling room at each end, of a main floor, a perforated false floor arranged above said main floor, a main ceiling inclined in opposite directions from the center to the ends of the car, and a perforated false ceilin arranged below said main ceiling, substantially as described.

In witness whereof, I have hereunto set my hand this 31st day of March, 1903.
