JAMES H. ORAXVFORD, OF CHICAGO, ILLINOIS.
REFRIGERATOR-CAR.
SPECIFICATION forming part of Letters Patent No. 593,012, dated November 2, 1897.
Application filed February 12, 1897 T 0 ctZZ whom it may concern:
Be it known that I, J AMES H. CRAWFORD, a citizen of the United States, residing at Chicago, county of Cook, State of Illinois, have invented a certain new and useful Improvement in Refrigerator Cars; and I declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same, reference bein g had to the accompanying drawings, which My invention relates to refrigerator-cars, and has for its object supplemental means whereby additional cooling-surface may be afforded by the cold water obtained from the melting ice in the ice-bunkers or refrigerating-tanks proper.
Figure -1 is alongitudinal sectional View through one end of the car, showing one of the ice-bunkers or refrigerator-tanks ine1eration. Fig. 2 is a cross sectional view through the car, that portion to the left of the central line being through the car-door, while that portion to the right is taken near the end of the car with certain parts broken away. Fig. 3 is a side elevation of the icebunker or refrigerator-tank. Fig. 4 is a plan view of the same. Fig. 5 is a side view of the auxiliary cooling-chamber. Fig. (i is a View of the drip-cup. Fig. 7 is a cross-sectional view of the auxiliary cooling-chamber, showing the pipe connection with the icebunker and by arrows the direction of the water in circulating through said auxiliary chamber toward the point of discharge.
In the drawings, A represents the car.
13 is one of the ice-bunkers located, preferably at each end of the car and supported from below and on the sides by suitable timbers c, and provided with hatchway-doors D at the top.
E is an. auxiliary cooling-chamber located adjacent to the ice-bunkers and preferably formed of sheet metal and having dividingwalls e on the inside, as shown in Figs. 1 and 7. The walls 8 are separated to form an air-space 6, so that. the air in circulating may pass between the two cooling surfaces or walls 2 in the chamber E.
G is a pipe leading out near the bottom of Serial No. 623,125. (No model.)
the ice-bunker and connecting one side of the auxiliary cooling chamber. From the top of this chamber, on the same side as the pipe just referred to, leads the pipe H, connecting at the bottom the channel on the op posite side of the auxiliary cooling-chamber. From the outside of the cooling-chamber E, near the top, is the pipe I, connected with the drain-pipe 1, leading into the drip-cup J, lo cated beneath the car. The upper portion 1' of the pipe 1 serves as an air-vent.
K is a pipe located near the bottom of the auxiliary cooling-chamber used in cleaning said chamber.
v The drip-cup J is mounted beneath the bottom of the car and is preferably hinged, as shown, to aiford easy access and is also provided with suitable means for securing the cup when in position. On the inside of the drip-cup is an overflow-pipe j to carry off excess of water.
Leading out from the bottom of the ice chamber or tank B is the pipe B under the control of a suitable valve. This is brought in use when it is desired to clean or drain the ice-bunker.
The operation of my device is as follows: The ice bunker or tank having been properly charged, the water from the ice as it melts will pass out through the pipe G and by natural pressure will rise in one side of the auxiliary cooling chamber E until it reaches the top. It will then flow down through the inclined pipe H until it reaches the opposite side of the coolingchamber, when it will again begin to rise until it reaches the top, when it will pass out through the pipe I, which, by means of the pipe I, will conduct the water to the drip-cup J. Here a Water seal or trap is formed by the pipe j, in order that it may effectually prevent the warm air from the outside securing an entrance into the car.
What I claim is- 1. In a refrigerator-car, the combination of an ice-bunker, an auxiliary cooling-chamher having dividing-walls therein forming channels for the passage of water, and an airspace between the same, pipes connecting the ice-bunker with the cooling-chamber, means to afiord communication from one side of the cooling-chamber to the other, and pipes for conducting the water to a point of discharge, substantially as described.
2. In a refrigerator-car, the combination of an ice-bunker, an auxiliary cooling-chamber having dividing-Walls therein forming channels for Water, said channels separated so as to form an air-space between the same, pipes connecting the ice bunker with the cooling-chamber, means to afford communication from one side of said cooling-chamber to the other, pipes for carrying off the water from the cooling-chamber, and a trap located on the line of said pipes near the point of discharge substantially as described.
3. In a refrigerator-ear, the combination JAMES H. CRAWFORD.
