Abstract
225,856. Soc. Generale Agricole. Dec. 4, 1923, [Convention date]. Mercury switches. -A tilting mercury switch k closes or opens the circuit to a pumping motor d, e according to the level of the liquid in the tank n. The tube k is fixed to a member t pivoted at s and a lever r<1>, r<2> also pivoted at s carries two adjustable pins r<1>, r<2> adapted to engage the member t w i t h a certain amount of lost motion. When the level of the liquid falls, a float p also falls and causes the pin r<2> to tilt the member t till a roller u, situated within the member t, rolls to the left and further tilts the member t till it strikes the pin r<1>, the mercury in the tube k simultaneously flowing to the left and completing the circuit between a contact j<1> and the casing of the tube.
