October 7, 1911.] ELECTRIC RAILWAY JOURNAL. 669 THERMOSTATIC CONTROL OF ELECTRIC HEATERS ANDTILTING HEAT DEFLECTOR unit possible. The deflector is made up in many differentstyles so that it can be attached to all classes of standardseats. The Consolidated Car-Heating Company has recently puton the market two devices for use on cars with electricheaters. One is an electric thermostat for controlling thetemperature of cars by turning the electric heaters on andoff at a predetermined point, and the other is a tilting heatdeflector. The thermostat proper is made of two metals with dif-ferent coefficients of expansion, which work according towell-known physical laws and whichnever vary. Hence when they are onceset they can be depended upon to main-tain absolutely the temperature at a ROLLER BEARINGS ON SUBURBAN CARS.
