s through thegrooves or corrugations g, passing out of the heater by pipe i,and so on to the trap T. In its passage through the heater itsheat is absorbed by the bricks, which have the property oftaking up quite a considerable quantity of heat; this heat isthen given out and diffused throughout the car. THE SAFETY COMPANYS SYSTEMS. 53. As is the case with the Gold Company, the SafetyCompany uses several different arrangements, or systems, whichwill be described in turn. In each one the main scheme is thesame, the steam supply being taken from the locomotive andpassed along a train pipe running underneath the cars thewhole length of the train, a train-pipe valve under each carallowing the steam supply for that car to be taken from themain pipe. ENGINE EQUIPMENT. 54. Fig. 18 shows the arrangement of the engine equip-ment. Steam is taken through a dry pipe p in the interiorof the dome, as shown, the pipe opening into the highestpoint of the dome and leaving the back head of the boiler at

§13 CAR HEATING. 43 the point a. The valve F controls the steam supply from theboiler. R is the pressure regulator which regulates the pres-sure to the train. A pressure gauge G is connected with theside of the regulator, and thus indicates the steam pressure onthe train. The pipe P runs to the rear end of the engine,where it receives the union u. Connection is made here withthe steam coupler (7, which in turn connects with the pipe Fthat runs to the rear of the tender and is fitted with a steamhose C Its rear end is 12 inchesfrom the center line of tender and 33inches above top of rail. STOP-VALVE. 55. The stop-valve included inthe engine equipment supplied by theSafety Car-Heating Company is illus-trated in Fig. 19, which shows thevalve in section; it is not essentiallydifferent from the one shown in Fig. 7,except that in the present case thebonnet H is secured to the body ofthe valve by the screws /, whereas in Fig. 7 it is screwed intothe body by means of the hexagon H.
