Abstract
23,899. Moffat, W. A. Nov. 20. Feed-water, heating and controlling.-In gravityfeed apparatus, arrangements -are made for automatically supplying the feed-water when the water level is low or the boiler pressure is high, and for allowing the engine to draw steam from the feed tank instead of from the boiler when the pressure in the former is too high. The feed tank B, arranged around the flue of the-boiler A, is supplied with water through pipe 6 provided with a valve 7 controlled by means of a rack 9 carried by the yoke 10 attached to a float 11. The steam-. pipe 14, connected to the steam -dome 3, passes helically through the feed tank and terminates above the level of the water therein. The admission of steam to the pipe is regulated by the valve 15 connected to a weighted pivoted lever 16 to which is also attached a valve 20 regulating the passage of the feed-water through pipe 19 to the boiler. A valve 26, admitting steam to the engine pipe, is connected through a bell-crank lever 28 with a plate 30 arranged to be operated by the float 11. A float 31, placed in the boiler, is connected by a chain with the lever 16, so that, on the level falling or the pressure being too high, the lever rocks and valves 15, 20 are actuated to permit the passage of steam and feed-water respectively. At the commencement of operations, if tank B is full of insufficiently-heated water, the hand-operated valve 19<a> is closed and the lever 16 manually operated to raise the valve 15 to admit steam to the coil. When the water has attained the desired temperature, the valve 19<a> is opened and water then passes to the boiler by gravity On the valves closing, the steam pressure in the tank B prevents. the opening of the check valve 6<a>, and when the float 11, owing to the falling of the water level in the tank, has caused the valve 26 to close, the engine draws steam from the tank through pipe 14 and branch pipe 21.. When the pressure is consequently sufficiently reduced, water again flows into the tank, the valve 26 is opened by the rise of float 11, and the parts are in readiness for a repetition of the movements.
