Abstract

965,541. Speed governors. PLESSEY CO. Ltd. Nov. 21, 1960 [Sept. 4, 1959; Sept. 18, 1959], Nos. 30216/59 and 31858/59. Heading G3B. [Also in Division H2] In a centrifugal electric switch, the governor weights 35 each have two inwardly extending lugs 38 which project into compression springs 30, 31. The weights are pivoted to the outer edge of slots 32, 33 formed in a rectangular frame 20 which is provided with a boss 22 to secure it to a shaft 23. Ears 21, extending from each end of the frame 20 limit the movement of the weights. A switch actuating element 24, having an annular contact surface 25 has its arms 26, 27 bent at each end to enclose the frame 20 and bent in the opposite sense in the middle to form fingers 29 which engage between adjacent turns of springs 30, 31. In operation the weights pivot outwardly away from each other causing the springs to snap over their dead centre positions forcing the finger 29 and actuating element 24 away from a contact assembly 12 &c.
