C.1910, English, Automatic Memorandum Clock, by the Automatic Memorandum Clock Co., 42 Holborn Viaduct, London, in generally fair to good condition. This was one of the first attempts to market a periodic alarm clock for persons needing reminders for taking medicines or other treatments. You insert small ivory discs in various time slots, and when they fall through a tin channel in the case, they tip a scale below the dial, completing a battery circuit that rings a bell under the clock. The disc is presented at the front of the clock for re-use. The movement is a robust open spring affair with a drive shaft out the top of the movement for the time-slot wheel. The case has several dry splits, but is complete with both original instruction labels. No battery and wiring is distressed; hands do not match. Very uncommon in the US. Height 13"
