Abstract
12,514. Pope, A., and Rayner, A. B. June 3. Lifts, alarms and danger indicators for. At each landing an electric bell circuit is arranged in such a way that the circuit, normally open, is closed whenever the well gate is open or opened in the absence of the cage. Fig. 1 shows a diagram of the arrangement. The gate carries a spring contact g which, when the gate is open, contacts with a plate f and closes the circuit. When the cage, however, approaches the landing, a non-conducting projection e upon it passes between spring contacts d and opens the circuit. The call circuit may be combined with this alarm circuit.
