Abstract
189,777. Metropolitan-Vickers Electrical Co., Ltd., (Assignees of Aspinwall, L. M.). Nov. 29, 1921, [Convention date]. Cut-out arrangements; automatic circuitbreakers.-In motor control systems such as those employed on trackless trolly vehicles, a line switch is opened automatically, when one of the current collectors becomes disengaged, either, as shown in Fig. 1, by the failure of an electromagnet 28 normally holding the switch operating lever 26 fast to a pedal-actuated accelerating-lever 22, or, as shown in Fig. 3, by the electromagnetic release of a spring-actuated striker 47 which forciblv carries the switch handle 41 to its off position. In the open position shown, the latching- plate 51 prevents the striker from being pushed back until the magnet 56 is energized.
