Fig. 7.âCross sections showing floor insulation of different types of refrigerator cars: a, Type A; 6, type B; c, type 0; d, type D; e, floor insulation separated into three layers;/, 1-inch layer of hair felt with two uninsulated subfloors. roof insulation. The floor insulations of the four types are about the same and are very similar in thickness to the walls. ICE BUNKERS. Each of the types A, B, C, and D is equipped with a characteristic ice bunker. Type A uses the siphon bunker shown in figure 8. Type B has the galvanized-iron box shown in figure 9, the box being perforated to allow the air to come in contact with the ice. Type C has two large, reenforced wire baskets (fig. 10), which permit free contact with the air. In front of the basket ice holder there is an insulated wall, with an open space at the top of the car for the admis- sion of warm air and a similar space at the bottom for the escape of the cold air. Type D uses the iron tanks shown in figure 11. With such tanks the ice can be crushed very fine, permitting a uniform.
