To all whom it may concern;

Be it known-that 1, CHARLES F. JAURIET,

' of Chicago, Goolicounty, Illinois. have invented certain Improvements in Refrigerator Cars, of -which the following is a specification.

' My improvements relate to that-class'of; re-j i'rigerator-cars in which the walls; floor and roof are hollow, and in which provision isinalde' for the automatic establishment of currents of air through ice-chests in the opposite ends of the ear and my invention consists in the ar 'rangement beneath each ice-chest'of a'dripf pan, the bottom of ;which has numerous pervents the water fromithe melted icelfomfall ing hrough the, perforations of the drip-pan by soljdirebtingitthat it fallson those parts oftheidrip-pan which are not perforated. By

tliismojd e of construction an unusually ample area of outlet is provided for'the fallfrom the chestof air cooled by contact with-thefice.

I arrange on the inner walls of the chest vertical wooden slats to establish spaces be- .tween the walls and the ice, and thus facilitate the passage of air through the chest.

'lngdisposing of the d rip wate'r I' {employ a trap-box divided by a "central vertical partition into two compart- "ments,.each'of which is provided with a handh'ole, permitting access. to the compartment for the purpose of cleaning it whenever necessary.- j 1 In the accompanying drawings, represent 'ing a'refrigerator-car embodying my improve- 1 is a transverse section.

Thedrawings repreSentthQbody Aof a reirigerator-car.having air-spaces 'in its walls established by means of the inner casings, a, and partitions a. For the partitions a I em-: ploy oiled pasteboard," or preferably awoolen fabric. A lining of like material may be usefully applied to the'casing-boardsd within the air-space, if desired. Y I

' Each end of the ear is provided with an icechest, B. ,The front biof each'fc'hest, on the inside, which may eitherbe removable or fixed, as desired, is provided 'with a door, I), by

7 hich access may be hadto the interior of the ice-chest,- and also with openings I) for the ad-' mission of air into the upper part of the icechest. The innerfwalls of the ice-chestare provided with upright slats O, forthe purpose' of establishing vertical passages through which airfi'ntroduce'dinto the top: of the icechst may pass" downward. v

. I provide in the ice-chest the wooden frameor rack D for supporting the ice. This racli is preferably made in two divisions, each of which inclines toward the center, as shown in Fig. 5. Below the rackis a drip-pan, E, preferably made of sheet metal, and fastened to the bulk-head and the sides of the car. The

bottom of this pan contains numerous perforations 0, the edges of which are each provided with short upwardly-projecting flanges, as ,shown in Fig. 5. Thesejflanges may-be formed by turning up the material of the pan "itself,

or by soldering or otherwise securing; short tubes to the pan. The openings in the drippan permit the cold airfrom the ice-chest-to fall through into that part-pf the car beneath the ice-chest. The flanges around these open ings prevent the fall 011 the car-floor of water contained in the drip-pan. The bottom of the drip-pan is inclined from each end toward the center, where there isa discharge-opening, c. ,It' will, of course, be understood that the di- "rection of the incli ation m y be Varied: n

- forated. I preferably provide'the perforations shape of the flanged openings in the. drip-pan ately under the perforations f in the shieldplates F. The form and inclination of the of the inclined bottom 9 there isan-opening, 9, provided with a nozzle partments by h' foreach of the compartments h and h, and by this means am enabled to clean these comment h to prevent if varied, that the position of the discharge; openings must be likewise varied accordingly. Between the drip-pan and the wooden rack D, upon which the ice rests, is a perforatedshield-plate, F, which is suitably supported in such a position that water falling through theopenings in the shield-plate drops upon those parts of the drip-pan which are not perdoor, 0 The I provided with tight joint-wit f in the shield with downwardly-projecting flanges, which serve more certainly to so direct the drip-water that it shall not fall through the openings in the drip-pan. L

- It will be understood, of course, that the the ends is immaterial, so long as such openings are provided with shields, or, in other words, so

A pipe, 2', 11 long as they do not occupy positions immedishield-plates F are the pansv If desired, springs may be placed under the racks D to elevate them as the ice decreases in weight by melting. v

Immediately below the discharge-opening c is a hopper-or chamber, G, for receiving the water from the drip-pan. Atthelower end of the chamber G made to correspond with which, having ice, has fallen extending down into a drip-box, H. The lower part of this drip-box is divided into two com- .a partition, h, the upper edge of which reaches slightly above the lower end of the nozzle g, as shown in Fig. 2. 7

Inoperation, the drip-water falling'through the nozzle 9 is ,discharged into and fills the compartment h, and thence flows over the top of the partition it into the other compartment, If, at the bottom of which is a pipe,'h which extends through the bottom of the car, and serves to discharge the drip-water outside the car. The lower end'of the nozzle 9 is sealed by the water contained in the chamber h, and solid materialsor dirt carried out'of the icechamber by the drip-water are caught in the compartment hi and preventedfrom clogging the discharge-pipe h I provide hand-holessho be e v r iilent, the the openings the latter.

This packing I ingrooves in partments when necessary.

Salt may beintroduced into the compartthe water from freezing in strips, so as to cold weather. between them The trap-box may, if desired, be set a little abov'ethewater-box, as shown in dottedtlines in Fig. 2, and, of course, the position ofthe partition k may be so varied, if desired, as to increase the size of the compartment h, and, thereby provide a larger reservoir for the salt and water. 1 It will, of course, be understood that if there is a. discharge-opening at each end of the drippan there must be likewise a trap-box for each discharge, and that the construction of the,

trap-box may be modified'to adapt it to its are packed at like the walls F, substantiall location. forth.
