7814. Wouwermans, P. von, and Loewenstein, L. March 31. Plug cocks; actuating valves and cocks.-In apparatus for compressing, mixing, and collecting definite quantities of air and gas for supplying incandescent lamps, a special multiple-way cock is actuated by the movements of the gas collector. The collecting-bell 24 is guided by rollers running on rods 26, and carries a U-shaped rod 28 moving in a water seal and provided with stops for moving the cock 50 and the motor switches. If the bell sinks completely down, the stop 43 releases a lever 51 and allows the weight 52 to turn the cock 50, thus cutting off the pipes 35, 20 and connecting the gassupply pipe 53 with the consumption main 54. The passages in the cock 50 are so arranged that all four pipes 20, 35, 53, 54 are cut off in intermediate positions of the cock.
