Abstract
183,357. Perrett, I. G. July 25, 1921. Moving-chamber apparatus.-In apparatus for adding powders to liquids, particularly for adding a softening re-agent to a domestic water supply, a wheel arranged beneath a powder hopper and provided with measuring pockets for the powder is rotated step by step by means actuated by the passage of the liquid to cause it to deliver the powder from one pocket on each delivery of liquid. As shown, a shaft 8 is oscillated at each discharge of liquid and at each oscillation a pawl on a weighted arm 13 on the shaft acts on a ratchetwheel 15 which, through bevel gearing 16, 17, intermittently rotates a shaft 18 passing down through a powder hopper 19 and provided with an arm 21. This arm causes powder to fall through an orifice 22 in a diaphragm 20 into the lower part of the hopper whence it is fed by arms 23 on the shaft through an elongated orifice on the bottom of the hopper into pockets 25 in a measuring wheel 26 rotated step by step by a toothed wheel 27 on the bottom end of the shaft 18. At each movement of the wheel 26, the powder in a pocket 25 is delivered through an orifice 29 in a plate 28, the delivery preferably being assisted by the depression of a plunger 31 by a cam 33 on the shaft 8 against the action of a spring 32. In an alternative arrangement the shaft 18 may pass outside the hopper and be keyed to the wheel 26 which drives a shaft carrying the arms 21, 23 through the pinion 27.
