HANCOCK COAL SPRINKLER A sprinkler manufactured by the Hancock Inspirator Com-pany. New York, for wetting down the coal on locomotives, wasdescribed in the Railway Age Gazette, Mechanical Edition, June,1513, page 334, and an improved form in the issue of Septem-ber. 1913, page 510. A further development of this device,superseding the other two forms, has recently been brought out. This sprinkler acts on the principle of an ejector. The prin-cipal feature is a valve which automatically discriminates be-tween steam and water and whose action prevents any suddenand unexpected discharge of steam through the hose. The de- DELIVERY. SUCTION Section Through Improved Hancock Coal Sprinkler vice is generally applied on the stramer or on the suction pipeof the injector by the use of a short connecting nipple having abend so that the sprinkler will be in a vertical position. A valveis placed in the steam pipe at a point where it can be conveni-ently reached. In operating the coal sprinkler, the steam valve in the pipe isopened wide, which action opens valve /. This also closes thedrip hole B, the piston end on the lower end of the guidingstem covering the hole. Steam will now flow through nozzle 4forming a jet and combining with water in tube 5. There willnot, however, be a flow of steam in starting, as tubes 4 and 5are always under water because of the location of the sprinklerat a point lower than the tank. Steam flows into the pressure chamber A and valve 2 israised. Port C is also closed and the water is forced throughthe delivery pipe to the hose. Should the flow of water be interrupted or
