Application led April 17, 1907. Serial No. 368,791.

To all whom it may concern:

Be it known that I, CHARLES A. MOORE, a citizen of the United States, residing at St. Paul, in the county of Ramsey and State of Minnesota, have invented a new and useful Improvement in Refrigerator-Cars, of which the 'following is a specification.

The primary object of this invention is the production of a refrigerator car ofimproved construction which 1s adapted to prevent the racing of ice on the floor of the bunker. A further object is the production of a strong and durable ice bunker in the to of acar with its ends remote from the en s of the car, said bunker being provided with an improved iioor, which performs the function of prevent-ing the ice moving too freely' therein, and at the same time is adapted to drain water efliciently from the ice. De# pending in part upon these requirements `my invention comprises the features of construction and combinations of parts hereins after described and claimed.

In the accompanying drawings, forming part of this specification, Figure 1 is a longitudinal vertical sectional view of a portion of a refrigerator car illustratin my invention; Fig. 2 is a plan view partin section on the line Z-Z of Fig. 1; Fig. 3 is a cross section of Fig. 1 taken on the line Y--Y; Fig. 4 is another cross sectional view of ig. 1 taken on the line X--X; Fig. 5 is a detail of a horizontal sectional 4view of a portion of the car, looking down upon its iloor immediately above the heating ap aratus; Fig. 6 is a det-ail perspective view o the I beams used in the ice bunker showing the method of joining the same.; Fig. 7 is a detail sectional view of the side of the refrigerator car illustrating the manner of fastenm the I beams in the ice bunker;l Fig. 8 is a etail4 sectional View of a portion of the ice bunker showing `the door construction thereof and one of the drains leading therefrom; Fig. 9-v is a plan view of that ortion of the ice bunker shown in Fig. 8; ig. 10 isa detail Fig. 9, and Fig. 11 isa detail sectional view -illed with material of any the lower portion of-one lyingtrans'versely'o the car showing the air-con# Y facilitate drainage.

o not the application of my Vparticular improvements to the special andgeneral construction. shown in the drawings. The walls, iiooring, and roof of the car are referably made double, treble, or quadrup e with any desired number of dead air s aces E between the separate portions o the wall which air spaces may, if desired, be filled with any suitable material which will serve of the car. The 1nfor live air and not kind and is adapted to conduct the hot and cold air issumg from the heater and ice bunker G into the car. The inner space Fis formed by the inner walls of the car and the'lining 2, the latter being placed a shortdistance from said inner walls.

The ice bunker G consists of a tray I which is supported on the sides substantially midway between the ends of the car by transverse and longitudinal I beams 4 and 5 and channel beams 5', said beams being connected at their intersecions by angle plates 6 (see Fig. 6) and rive s 7 passino through said angle plates and I beams. The ends of the I beamsare fastened to the sides of the car by means of bolts 8 passingthrough a portion of the frame of the walls and the longitudinal channel beams. The tray of the ice bunker is made by restinglayers of floor planks 9 across the lower flanges of the beams `and placin thereon longitudinal strips 10 upon which transverse an le slats 11 are placed with their apexes irected upward.

to insulate the interior ner space F, however, is

The blank bottom -of the tray maybe rendered watertight for drainage purposes in any suitable manner. The angle slats support the ice in the bunker and the water from the ice drips between said slats upon the door of the tray from which passes to the exterior of the car throu h es 12 extending-downwardly through t e si e walls. The transverse beams extend upward for a part of their height into the ice bunker forming stops to prevent the skiddingof 'the icein vthe bunker. The sharp upturned backs of the angle slats 11 f the bunker engage the ice and tend to prevent longitudmal movement.` The floor of the bunker as illustrated is substantially horizontal but may be sloped toward thei sides .of the car if' desired to The frame-"of the car reinforced by adjoining the ice bunker is the car and the braces 13.' The ends of the ice bunker are of open work construction and provided with' downwardly and inwardly inclined horizontal slats 14, which are spaced apart, so that air may-paw through the ends of the bunker freely. Cold air being heavier than warm air passes from the bunker after being cooled by ice therein through the openings between theY slats 14 down into the lading chamber in the car, and warm air in the top of the car passes through the openings 15 in the ends and sides of the car, and to the ice bunker through the fines F. f i

It is understood that the ends of the bunker are of construction similar to each other, the drawings illustrating but one end.

The openings 15 are provided with horizontal slats 17, spaced apart, and the openings 16' with a cover of wire netting 18 (Fig. 11). In the roof of the car are hatchways 25 enteringthe ice bunker and having inner' wallsV 26 contracting toward their lower` ends so that Stoppers 27 can be inserted in sald openings to seal the passageways through which ice is placedin the bunker. Doors 28 are adapted to close the `openings 25 in the usual manner. Chains, 29 having their ends connected with the frame of the roof and the Stoppers 27 are adapted to pre.

vent the Stoppers being carried away when they are jremoved.

The heater H consistsof a chamber 30 having suitable heat insulated walls 31 which are suspended below the loor and substantially midway between the 'ends' of provided with a doorway 32 (Fig. 4f)y through which access can-be had to l the interior of said chamber.v In this heatmg chamber is placedya stove 33 which carries a supplyv of oil or any suitable fuel.

Air is admitted to this heater by valved passageways 34 leading throu h the Walls of the heater and conducted t erefromA by the space F which opens into each end nearl `the ltop of the heating chamber as shown.

A suitable vent pipe 35 leads from the heater and is divided into branches 36 through the side walls andI roof of the car for the escape of gases or smoke. The heatermay be of any suitable form and may be' operated by oil, coal, or other suitable fuel. It is obvious that the heat may be generatedin the heating a coil supplied with steam from a'locomotive without departing from the principles which lI have applied.

In operation, when it is desired to cool they atmosphere in the car, is placed in the bunker through the hatch'ways in the roof `which are afterward sealed. The cold air from the vbunker passes 'down into thecar throu h the openings between the slats 14 and t e warm air 1n the car' returnsinto the bunker` through the openings 1'5 'the' ends and sides of the car.. When the car is chamber byused for cooling purposes, the valved inlets 34 are closed. When it is desired to heat manner warm or cold air freely circulates i throughrthe car when the heater or refrigerator is` in operation. Outside air also enters Ythe heating chamber through the. openings 42.`

A ventilator '38 in the roof of the car and enter the ice bunker is provided. Normallyill'is ventilator is closed by avalve 39 pivoted upon a support 40 and carrying a counter-weight 41. To open this ventilator, the valve is swung-completely around its pivotsupport 40 with its counterweight on the opposite side of said support to that illustrated in Fig. 1. When the ventilator 38 and the valves 37 'arepopened and the car is at rest or in motion fresh, air is admitted into the car and freely circulated therethrough. By properly Ventilating the car, l

'fruit and other commodities in'transit are kept fresh and ating. Y

In accordance-with the patent statutes, I have described the principle of operation of my invention, together. with the apparatus prevented from deterior- `which I now consider to` represent the best embodiment thereof, but desire to have it y understood ythat the apparatus shown is only illustrative and that the invention can be carried outlby other means and ap liedv to uses other-.j than those above set orthY ,within the scope of the claims.

Having described myinvention, what I claim as new and desire to protect by Letters Patent, is l 1.
