Abstract

181,859. Cheetham, G. A., and Metropolitan - Vickers Electrical Co., Ltd. March 31, 1921. Drawings to Specification. Cut-out arrangements for opening a circuit on overload and automatically closing it when normal conditions are restored by means of a Wheatstonebridge connection as described in Specification 162,267, include in the restoring circuit a timeelement device adapted to delay the re-connection for a predetermined interval after the removal of the overload. The time-element device may be a dash-pot attached to the tripping plunger of the auxiliary switch which when closed energizes the closing coil of the main switch. The coil of the tripping plunger is connected across two diagonally-opposite points of the Wheatstone bridge, and across the other two similar points a resistance may be connected.
