CAR-DOOR CLOSURE.

Specification of Letters Patent.

Patented Sept. 20, 1910.

Application filed January 17, 1910. Serial No. 538,509.

To all whom it may concern:

Be it known that I, ARTHUR FAGET, citizen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented a new and useful Car-Door Closure, of which the following is a specification in such full and clear terms as will enable those skilled in the art to construct and use the same.

Thisy invention relates to an apparatus for the purpose of precooling the air in refrigerator cars, the object being to reduce the temperature of the air in the car, together with the contents thereof, to the desired temperature, prior to the shipment of the materials. It will be understood by those familiar with the art that it requires some considerable time to reduce the temperature of fruit and other perishable articles, to suitable temperature for transit, if the materials are simply placed in the car and ice supplied to the bunkers. The disadvanta e of this is that from three to live days e apse before the desired low temperature is attained, during which time more or less decay may take p ace.

The apparatus illustrated and described in this specification is intended for the purpose of handling the air used in precooling the car and contents, and the particular object of the invention is to distribute the cold air in the car in such a manner as to prevent injury to the materials to be cooled.

In precooling the car and contents, air is used as cold as the articles to be cooled will ermit that is with an ordinar refrigera- P a a o tion plant, say from freezing to several degrees below zero, the object being to detain the car as short a time as possible, and to cool the fruit to a temperature of about 40 Fahr. in as short a time as possible. Since this air is so cold, it would freeze any fruit or other perishable vegetables very quickly if allowed to strike the same directly. It therefore becomes necessary to provide means for diifusing the cold air in such a manner as to completely cool the air in the car together with the contents thereof, while at the same time preventing the cold air from the refrigeration plant from striking the fruit or vegetables.

In the drawings, in which the same numeral of reference is applied to the same portion throughout the several views, Figure l illustrates a central vertical sectional view through one of the car door plugs, and

a portion of a car the pipe 8 being shown in full lines; Fig. 2 represents a front elevation of a portion of a car and one of the plugs; Fig. 3 represents a horizontal sectional view of one of the plugs and a portion of the car on a larger scale than Fig. 1; Fig. 4 is a plan view of a portion of a car, and one of the hatchway lugs; and Fig. 5 is a vertical sectional view of the plug shown in Fig. 4 on the line 5 5 thereon.

The numeral 1 is applied to the car body, and 2 represents the side wall of the car, the said wall of the car being provided with doors 3-3- The doors are opened and a plug f -t is inserted in the door opening, said plug having pneumatic tubes 5 to make a tight joint with the door jamb, lintel and sill. Near the upper portion of the plug there is a box-like caslnfr G, supported by means of braces 7 into which an air-pipe 8 leads. The side of this plug next the car contents is provided with two

cross-bars

9 and 10, said bars supporting a curved plate 11, which extends to the bottom of the box 6, and against which the air from the pipe 8 impinges on entering the car. This curved plate causes the air to be deflected npwardly, Iand in order that it may be properly distributed in the car, four other

curved plates

12, 13, 14 and 15, are connected with the plate 11. These four plates are curved laterally, and are straight vertically. The

plates

13 and 14 are connected at 1G, and form a curved wedge, while the plates 1Q and 15 are spaced away from the plates 13 and 14., and are substantially parallel therewith. The result of this construction is that the air passing through the pipo 8 in the direction of the arrow, strikes the plate 1l, is directed upwardly, and is spread out in the shape of a fan by means of the plates 12 to 15, the body of the air forming the fan extending in the neighborhood of the car roof, and away from the car contents. Where convenient, other plugs will be connected with the hatchways of the car and the air will be passed in through pipes 8 and within the car through the hatchways thereof. But under certain circumstanfws, it may become necessary to reverse the current of the air, and since it is not desirable to change the car equipment, since there are great numbers of standard refrigerator cars, having a given equipment, a plug such as is shown in Figs. 4 and 5 may be used. In this case the plug is provided with means for makingl a tight joi-nt With the hatchvvay of the car, substantially like the means shown in Figs. l to 3. The numeral 18 represents the car roof, 19 the running board near the center of the car, and 20 the rim of the hatchway. In this hatchvvay is inserted the plug 21, having the air pipe 22 secured thereto by means of a flange 23, rings 24: being provided for theconvenienthandling of the hatchway plug. Since the course of the air through the pipe 22 is directly down...

securing a series of three curved plates 25,.

26 and 27 to the hatchvvay plug at` the bottom of the pipe 22. Then, as the air passes into the car through the pipe 22, it will be.

- driven in the path indicated by the bottom of the curved' plates, thus spreading and diffusing the cold air in the car close to the roof, and preventing injury to the car contents.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the .United States, is as follows:

1. In a plug for car doors, a frame, means to make said frame air-tight in a door opening, an air pipe connected With said frame,

and deflecting means interposed in the path of the air to direct the air toward the roof of a car, as described. Y

2. In a plug for car doors, a frame, means to make said frame airetight in a door opening, an air pipe connected with said frame, and deflectors arranged in the frame at the end of said pipe so as to direct the air in a fan-shaped body toward the roof of acar, substantially as described.

3. In a plug` for car doors, a frame, means to make said frame air-tight in a door open-y ing, an air pipe connected with` said frame, and deflecting means interposed in the path of the air to. direct the air toward the roof -of a car, and comprising a series of curved plates adapted to spread the air into a fanshaped body near the roof of a car, as set forth.

4. In a plug for car doors, a frame, means to make said frame air-tight in a door opening, and an air pipe connected With said'VA ARTHUR FAGFET.
