Abstract
169,497. Brougham, F. J., (Vapor Car Heating Co., Inc.). June 22, 1920. Switches, actuating; pneumatic. - A manual control rod 22 is provided for switching over to the higher of two temperatures in a steam heating system for railway cars by which the lever H is pushed on to contact 24. On coupling up the cars with the engine for use, the air signal line K is put under pressure and the piston 12 in the cylinder J is moved, causing the lever G to pass on to the contact 24. At the same time the rod 13 pushes the lever H off the circuit 24 back to its normal position. The circuit through the higher temperature thermostat F remains the same, the lever G replacing the lever H. On uncoupling the cars from the engine the fall in pressure in the air line K and consequently in the cylinder J will allow the spring 16 to return the lever G, and the circuit will again be through the low temperature thermostat E.
