Abstract

23,139. Armstrong, C. G. Nov. 15. Heating buildings &c.-Relates to beating devices and systems, especially steam heating- systems, and to the process of regulating them. Fig. 1 shows a single-pipe steam heating-system embodying the invention, and Fig. 3 shows the construction and arrangement of the controlling valves and pipes. The heater or radiator has its effective radiating-area varied or governed by the insertion into the heater or radiator of a displacing- medium such as air, and the act of varying the radiating-area is checked independently of the temperature of the room to be heated, so as to prevent the too rapid insertion of the displacing- fluid. A valve F adapted to admit the beating- fluid to the radiator is located between the source of supply and the radiator, and the controlling- valve D with the valve C<1> governed by the thermostat C is placed so as to communicate with the radiator by the pipe E<6>, with the air supply or pump or reservoir D<2> by the pipe D<1>, and with the withdrawing-device or vacuum pump D<4> by the pipe D<3>. The air pipe D<5> is controlled by the thermostat, and the valves E<3>, E<2> open outwardly and inwardly respectively. The seating- spring E<4> is not so strong as the spring E<5>, so that the valve E<2> is more readily actuated than the valve E<3>.
