Abstract
9590. Berg, J. April 20. Actuating valves.-A time switch adapted for electric or other lighting purposes, of the kind in which the actuating-mechanism is unlocked in readiness for action a short period before the prearranged time of action comprises a cranked lever having an arm f adapted to be engaged by the timing mechanism, and an arm g having two projections e, g<1>, which are adapted to engage a locking-lever i and a pawl l respectively. The lever i has an arm i<2>, which normally engages notches in a cam k mounted on the main spindle o of the clock-train and connected to the switch or other device h, and an arm i<3>, which normally engages a stop in the clock-train. When one of the hands b engages the arm f, the locking-lever i is moved out of engagement with the cam k and with the clocktrain, but this is prevented from rotation by the engagement of the pawl l with the projection g', until the continued movement of the hand b releases the arm f, which springs back to its normal position and leaves a free passage for the rotation of the pawl l.
