Abstract

212,276. Worthington Pump & Machinery Corporation, (Assignees of Lucke, C. E.). March 1, 1923, [Convention date]. Nozzles and combining-tubes; regulating or controlling action.-Relates to those ejectors in which the nozzles or diffusers or both are shaped substantially rectangular in cross-section, with the shorter sides parallel to each other and small in comparison with the longer sides, which are inclined to each other. The longer sides are stationary, the shorter sides being adjusted to or from one another to vary the capacity of the jet without substantially altering the ratio of perimeter to area of cross-section. In the steamoperated air-ejector shown, the steam nozzle B has fixed longer sides 12, and the shorter sides 13 are adjusted separately or together by screws 11 fitted with lock-nuts. Suitable packing 1 is introduced. The convergent-divergent combining-tube D is similarly formed with fixed long sides and movable short sides 16 adjusted by screws 17, and it is set with its longer sides parallel with those of the steam nozzle. The shape may be used for nozzles or combining-tubes separately.
