Abstract
561,761. Controllers. DAVIES, F. W., and DAVIES, R. K. (trading as DAVIES & SON, F. W.). Dec. 10, 1942, No. 17558. [Class 38 (iii)] A " star-delta " or similar starter has its. drum shaft G<2> retained in the " start " position by a notch D<4> in an auxiliary trigger D\ and in the run position by a notch D<7> in a main trigger D, the auxiliary trigger being retained by a notch D<6> in the main trigger. The shaft is released from either position by the fall of a no-volt plunger V, by the lifting of an overload plunger 0, or by a manually actuated push acting on the trigger D. Specification 540,070 is referred to.
