Abstract

146,012. Eisner, S. Sept. 19, 1919. Clock-work actuation; flexible-pull actuation.- Relates to a clockwork device, for operating gas valves or electric switches after a predetermined time, of the type comprising an additional or alarm spring independent of. but controlled by, the mainspring. The winding key 2 of the additional spring is formed with an extension 3 having at its end arms of similar shape to those on the key proper, the portion of the extensions between the two sets of arms constituting a drum on to which a cord or like connector 4, controlling the valve or switch, is wound when the additional spring is released by the timing-mechanism.
