REFRlGERATOR-CAR.

SPECIFICATION forming part of Letters Patent No. 401,385, dated April 16, 1889. Application tiled September 19, 188B. Serial No. 285,799. (No model.)

To @ZZ whom t may concern.-

Be it known that I, WILLIAM l-I. l-I. Sismi, of Brooklyn, in Kings county, and the State of New York, have invented a certain new and useful Improvement in Refrigerator-Cars, of which the following' is a specification.

I will describe a car embodying my improvement, and then point out the novel features in a claim.

In the accompanying drawings, Figure l is a central longitudinal section of a car embodying my improvement. Fig. 2 is a transverse section of the car-bodyon alarger scale.

Similar letters of reference designate cor responding parts in both figures.

A designates the body of the car. It may be of the ordinary or any other desirable shape. It has double floors, walls, and roof.

a. designates the inner end walls.

h designates the outer end walls.

a2 designates the inner side walls.

h2 designates the outer side walls.

co3 designa-tes the inner door.

b3 designates the outer or lower door.

a* designates the inner roof.

bf designates the outer roof.

b designates a dome which forms part of the upper roof.

The lower floor, b3, is secured to the under side of the sills or longitudinal timbers s of the car-body, and the inner floor, a3, is secured to the upper sides of these sills. Obviously, therefore, the space between the two floors is divided by the sills into a number of longitudinal channels. The inner end walls, a', are secured to the inner edges of the end posts or stanchions, 19, and the outer end walls, h', are secured to the outer edges of these posts or stanchions. The inner side walls, a?, are secured to the inner edges of the side posts or sianchions, t, and the outer side walls, b2, are secured to the outer edges of these posts or stanchions. It will be seen, therefore, that the spaces between the inner and outer side walls are divided into a number of vertical channels, and that this is also true of the spaces between the inner and outer end Walls.

I have not shown any communication between the channels of the double floor and the channels of the walls. The channels of both the end and side walls communicate at the lower ends with the atmosphere below the car-body through openings c. Air may therefore enter these channels from the lower end. The heating of the outer side walls, especially where the sun shines upon them, will cause a rarefaction of the air within the vertical channels of the side and end walls. An upward circulation of air will result. The air will flow into the space formed between the inner roof, a, and the outer roof, h4, and into the large open space between the inner roof, a4, and the dome The sides of the dome b5 are provided with openings d, which may advantageously be covered with wire-gauze, and from which the air may escape.

By my construction of a car-body I secure an automatic circulation of air outside the inner walls which form the refrigerating-chamber, or, in other words, the chamber in which the freight of the car is packed. This circulation of air prevents any material heating of the inner walls and inner roof of the carbody and enables the freight to be kept cool.

The inner roof, a4, is provided with doors or valves e. These doors e extend lengthwise of the car-body, and are arranged at the longitudinal center of the inner roof, a4. They are connected to the inner roof by hinges, and may be raised and lowered more or less to vary the circulation or escape of air from the freight-compartment.

Below the middle portion of the car-body, and between the two sets of wheels by which the car-body is supported, I have arranged an icebcx, B. This ice-box consists of an inner and outer wall having an air-space between them. The inner walls, f, and also the outer walls, f extend downwardly from the lower Iioor of the car-body. The inner floor of the ice-box is depressed toward the center, so

that the water formed by the melting of ice within the ice-box may drain to the center and run out through central openings, g, with which the floors of the ice-box are provided. It may be observed that there is arranged above the upper 'floor of the ice-box a rack for sustaining the ice at a distance above the upper or inner iioor. The openings g will have combined with them a trap of any suitable construction to permit of the escape of water while preventing the ingress of air.

The lower floor of the ice-box is provided with openings 7L, through which air may as- IOO eend-to the space between the double side walls of the ice-box for the purpose of keeping the inner walls cool. Above the ice-box the inner floor, d3, of the car-body is provided with openings z'. These openings are arranged adjacent to the inner side walls, a2, and inner end walls, a', of the car-body. They are covered by distributers C. These distributers are shown as consisting of castings secured to the inner floor and inner walls of the carbody, and consisting of upright lower portions secured to the inner floor and oblique upper portions secured to the inner wal-ls. They are provided with numerous holes throughout their extent. Owing to this, air which may circulate from the ice-box into the car-body will be distributed throughout the car-body.

Air ascending from the ice-box will pass from the side portions of the ice-box directly upward through the adjacent openings t'. It Will'pass to the other openings z' after iiowing along the passages formed between the sills and the upper and lower iioors.

The car-body is shown as provided with a side door, A. This door operates in connection with a door-casing which closes the space between the side walls of he car-body. The ice-box B has a similar door, B.

If the natural circulation of air from the ice-box into the freight-chamber of the carbody is insufficient at any time, a more active circulation may be induced by opening the doors or valves e more or less, for the iiow of air over the opening controlled by these doors will induce an outward flow of air from the freight-chamber.

By my improvement I produce a ear suitable for meats and other food products, and which is simple in construction and comparatively inexpensive. The circulation of air around the walls, floor, and roof of the freightchamber will keep the freight-chamber cool, and the temperature of the freight-chamber may be maintained at a low degree by a comparatively small quantity of ice in the ice-box.

What I claim as my invention, and desire to secure by Letters Patent, is-

In a refrigerator-car, the combination, with the car-body, comprising double side and end walls secured to stanchions and a double roof, of vertical air-passages formed by the stanohions and double side and end walls and the double walls of the roof, said passages opening to the outside atmosphere at the bottom of the car and having an outlet through the roof, a floor for the car consistinglof two courses, an ice-box arranged beneath the floor and having air communication between said courses and through openings in the upper course with the interior of the car, deectors over said openings, and hinged valves in the inner wall of the roof, substantially as specified.
