Abstract

296,058. British Thomson-Houston Co., Ltd., (Assignees of Case, F. E.). Aug. 24, 1927, [Convention date]. Controllers, actuating ; multiple rocking bar; overload release devices.-In a controller for the circuits of electric motors or other electric apparatus, contact - fingers 10 - - 13 are successively closed by cams 14 - - 17 on a manually turned shaft 18, which can also move parallel to itself when a supporting toggle 26 is broken by an overload tripping-magnet 32. The parallel movement opens the contactors with the cams in any angular position.
