Suit for infringement of United States patent No. 1,166,224, issued to plaintiff December 28, 1915, on motoroperaied force pumps for water or other fluid.1 The features of the device, so far as important here, are sufficiently shown by a reproduction (reduced) of the patent drawing, in which 1 represents the [865] pump casing, 2 the inlet chamber, 3 the wafer supply inlet, 10 the pump cylinder mounted in the partition 9, which separates the inlet chamber from the valve chambers 7 and 8, 1¡, the discharge chamber, separated from the valve chambers 7 and 8 by partition 22, and provided with an air chamber 5 and a water outlet 6. In this partition 22 are parts 23 and 2J¡., respectively controlled by valves 25 and 26 located in the discharge chamber. There are permanently open air passages 27 between the valve chambers and the discharge chamber. The patent drawing shows and the specification describes these passages as in the form of nozzles 28, having their upper ends tapered, mounted in and extending above the partition 22, “which constitutes the bottom wall of the discharge chamber.”
