Abstract

265,824. Dale, W. B., Hopkinson, R. A, and Hopkinsons, Ltd. May 6, 1926. Switches, actuating.-A switch for use in an electric motor valve actuating mechanism having a positive clutch between the motor and valve spindle brought into the operative position only when the speed of the motor exceeds a predetermined minimum, comprises contact arms r, s carried by a spring loaded member q pivoted to a plate p on a shaft g driven by the motor h through gearing i, j. When the speed of rotation falls below a predetermined minimum the contact arms, connect slip rings t to short circuit the windings of a relay switch v.
