Abstract
610,793. Transmitting mechanical power. McEWAN & CO., Ltd., W., and FERRIS, J. T. T. April 16, 1946, No. 11732. [Class 38 (iv)] [Also in Group XXXVII] An electric motor drives transmission gearing through a slipping or friction clutch, and a centrifugal device, which is coupled to the driven member of the clutch, disconnects the motor when the speed of the driven clutch member falls on excessive load. An electromagnetic brake which is held off when the motor is energized is provided to prevent running back of a hoisted load. The clutch is shown as comprising a splined driving member a<SP>2</SP> on which is fitted a friction plate b cooperating with a plate c and a driven member d. The two plates are held together by means of springs g mounted on the member d. The centrifugal device comprises two rods which are slidable in a guide i and which carry weighted end members k having carbon contacts l. Springs m tension the weighted end members. The brushes l are adapted to contact with an annular member fast with the gearing casing.
