Abstract
232,781. Stevens, W., Hathaway, J. G., and Bartlett, B. W. April 30, 1924. Timechecking apparatus, check and token.-Apparatus of the type in which the insertion of the identifying member through an aperture in the clock casing starts the clock and closes the aperture comprises a tube A extending into the casing and having a curved slot A<2> near its open end and a longitudinal slot A<3> near its closed end. Through the slot A<3> works a pivoted lever C adapted to be depressed on the insertion of a pellet holding the pigeon ring so as to release a hook B from a spring-pressed arcuate slide D slidable in bearings J and urged in an anticlockwise direction by a spring G. On the release of the slide its end D<1> takes into the slot A<2> and closes the tube A, and a spring F fixed to the slide is moved out of contact with the balance-wheel M of the clock thus allowing it to start. A spring L engages with ratchet teeth D<3> in the slide D to prevent clockwise movement. The slide is provided with a handle D<5> to allow the parts to be reset when the cover of the casing is opened.
