To all whom, t may concern:

Beit known that I, WILL J. HUGHES, a citi? zen of the United States, residing at the city of St. Louis, State of Missouri,"v have invented certain newT and usefulImprovements in Refrigerator-Cars and I hereby declare the following to be a full, clear, and exact description of the invention, such as Will enable those skilled in the art to which it appertains 1o to make and use the same.

The object of ,this `invention isso to construct a refrigerator-car that access may be had to vthe storage space within the same without permittingv the ingress of hot air from the outside and the egress of cold air from said storage-place- To attain this end is important, because it is frequently necessary in refrigerator-car service to remove a part only of the perishable freight from Withzo in the car while the remainder is not'taken from the car until a subsequent time. This is true where some of the freight is intended for and removed'at way-stations... The particular construction of car made the subjectmatter of my present application is also useful where it is desirable to separate shipments, as in this construction a part ot' the freight is placed in one compartment and the rest of the freight in an entirely separate 3o compartment, and either portion` may be con-A veniently removed without disturbing the other.

Other features of invention connected with the refrigerating means will hereinafter 3 5 clearly appear in the specitication.- A Y With the above objects inviewthe invention consists in the novel features of con' struction hereinafter fully describedfgpa'rl' ticularly pointed out in the claims, and clearly' 4o illustrated by the accompanying" drawings,

in which n Figure 1 is a longitudinal sectional view of a refrigeratoncar, the side door of'sa'nie, however, being partly` shown in full; v HFig. '2 islaV horizontal sectional view, one end of same beingtakeuon the lines a b, Fig. 1, and the other-end onfthe line' o d, Fig. 1. Fig. 3 is a transverse sectional View on the line ef, Fig. 1. In the drawings, 1 indicates the side walls 5o of the car 5 2, the ends thereof.

These walls cated at' the ends of the car. V-ment of a series of water-tubes to drain off are formed in any desired manner; but I have shown them as usually constructed in refrigerator-carsl with an inner and outer shell with suitable packing between. 3 indicates the storage-compartments in the car, and 4 a vestibule extending between said storage-compartments and from one side of the car to the other. The ends of said vestibule are closed by the doors 6.- Leading from said vestibule 4 into the storage-compart- 6o ments 3 are the doors?.4 `Located adjacent to the roof', nearthe ends of thebar, are the ice-bunkers 9, which contain within them the ice-pans 10, supported slightly above the floor of said bunkers by the blocksll or in any other desired manner. Apertures 12 in the bottom --of said ice-pans 10 allow the Water arising from the melting of the ice, to iow out of the pan, and into the ice-bunker proper, which, in turn, is provided with apertures 13. 7o Apertures 13l communicate Withlwater-tubes 14, which servev to` convey the Water from the ice-bunkers to the lower part of the car, where they discharge'iuto the cross drain-pipe 15,pro vided with the upwardly-projecting cups or tubes 16, which telescope the lower end of the water-tubes 14, as shown in Fig. 3. The cross drain-pipe 15 is provided with the outlet 17, through which the water escapes to the exterior of the car. Communicating with the com- 8o `partments 3 and ice-bunkers 9 are the openings 18,'which allow the Warm air in the compartments 3, which naturally rises to the top ,of the car, to enter the ice-bunkers 9, Where it is cooled by contact with the ice, thus forin- 85 ing a circulation of air. When cooled, it is heavierjand passes through the openings 19 into theair-ducts 20, which are formed by the side Walls of a plurality of water-tubes 14, lo-

The arrange- 9o the ice-Water necessarily arising from the melting of the ice across the end of the car vincreases the refrigeration-surface in the storage-compartments 3andby reason of the fact 9 5 that they are placed close enough together to form the air-ducts 20. the ice-Water within said water-tubes 14 aids in maintaining the cool temperature of the air descending from the bunkers 9. As the water-tubes 14 teleloo scope With the projecting cups 16 of the cross drain-pipe 15 the cold temperature of the water draining through these pipes is preserved, enhancing the advantages secured by the construction and arrangement just described.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, isl l. In a refrigerator-car, a centrally-located vestibule, having outlets at both its ends through the side Walls of the car, and inlets through the compartments formed on both its sides, said inlets and outlets being controlled by doors, ice-bunkers arranged in the side compartments, Water-conduits leading downwardly from said bunkers, cold-air conduits arranged between said Water-conduits, and

pipes leading from said Water-conduits to the
