Abstract
327,169. Walker, J., and Walker, J. V. Dec. 31, 1928. Electric clocks.-An electric clock in which a short spring B is re-energized by a magnet E and drives ratchet and pawl mechanism H, G to the clockwork H<1>, H<2>, and in which the armature lever F has a fork A positively making and breaking the circuit, is provided with an adjustable timing screw I on one arm of the fork to vary the time during which the magnet circuit is closed. The fork A coacts with a lever C which is friction-tight on its pivot and carries a contact coacting with a fixed adjustable contact D.
