In the accompanying drawings, Figure 1 is y a vertical longitudinal section of one-half of my improved refrigerator-car, and Fig. `2 is a Similar letters of reference indicate corresponding parts.

The car is provided with two ice-chests, one of which is shown at A, the other being at y the opposite extremity of the car. in a car of ordinary size will be constructed to contain about eight hundred pounds of ice. y Bis a lap, hung on hinges, which -I prefer to i have eccentric, and when it is desired to be opened it is heldin position shown in Fig. l
