297,080. Moser, A. D. Sept. 14, 1927, [Convention date]. Gas heating-stoves. -A radiator containing gas-heated fluid for rooms comprises tubular c a s t iron units 11 held assembled at top and bottom by pressed-in tubular thimbles 14, 15 of wrought steel, preferably with gaskets 16 between the faces of the units. The heating chamber is formed by stall-like integral extensions 12 of the units with end covers 18, 19. Gas passing a valve 44 mixes with air from an adjustable screwed inlet 57 and flows along a tube 58 to a burner 20. The valve 44 is supported by a spring 45 and has a tubular cone 46 adapted to close on a seating 55 of a tubular neck piece 52 screwed into a casing 50. The valve is controlled by a flexible diaphragm 43 operated on by steam pressure in the radiator through a tube 41. When the valve is open, gas passes through the annular space 53, but when steam pressure closes it, gas enters by lateral ports 48, 49 and a by-pass comprising an internal axial tube 47 through the cone 46. The burner consists of an elongated box 20 with reamed holes 65 arranged as at Fig. 5 and rests on projections 21 on the base of the heating chamber, into which air is admitted only by slots 22 at the bottom of the units. Two end units carry legs and one carries an adjustable spring-pressed ball safety valve 24 with a depending steam pipe 26. On cooling, internal pressure falls, and a float 32 with a pin 33 normally closing a valve 34 also falls, and air is admitted to the radiator by the valve 34, holes 30 in a partition dividing the valve into two chambers and by pipes 27, 28 connecting the valve with the radiator. On heating, air escapes and finally steam enters and condenses under the float 32 to lift it and close the valve. The condensed water returns by pipe 27, and the valve is held closed by internal pressure. The water level in the radiator is kept below the valves and pipe 41.
