Abstract
272,776. Gunning, J. Dec. S, 1926. Clockwork actuation.-A spring- or motordriven spindle M‹, the step-by-step rotation of which moves a switch or valve alternately "on" and " off, " has mounted on it a disc O carrying four spring-pressed latches P which project in turned in a gap Q‹ in a fixed ring Q, thereby preventing rotation of the spindle M‹, till at a predetermined time the latch P is depressed by a clockwork-driven " on " or " off " tappet H or H<1>. Two of the latches P carry short pins p<1> and the other two latches carry long pins P<2>, and the one tappet H is so arranged that it engages the long pins P<2> only. Immediately after the disc 0 has been released, the pin of the succeeding latch comes into temporary engagement with the rear face of the tappet, this forming an additional safeguard to prevent overrunning of the spindle M‹. The timing tappets H, H<1> and the timing dial G are adjustably secured upon a sleeve D which is rigid with the hour wheel E, and the sleeve D forms a bearing for the winding arbor C of the clock. The spindle M‹ may carry a bridging contact arm or a cam which acts to raise and lower a pivoted arm dipping into mercury contacts, and it may be coupled to a rotary gas valve.
