Automatic Memorandum Clock Co., London, "Davidson's Patent Automatic Memorandum Clock", 8 day time and reminder, spring driven balance wheel movement in a walnut case with four full pillars and wooden urn on top, white enamel dial and blued steel hands. The case has an original, rubbed down finish. There is a very nice paper label under the lid of the urn. It is signed in ink "John Davidson", who invented this device. Whether the signature is authentic, we cannot say. The label is stamped "4001 ". The signed white enamel dial and beveled glass are fine. The old electrical wiring and bell mechanism are present and may need restoration. A plaque on the front shows at date of 1895. A time-only movement powers the clock and rotates a disk hidden within the urn. The disk has slots that correspond to different times of day. Memoranda, in the form of small dime-sized tablets, are placed within the slots. At the assigned time, a tablet falls through the slot, tips a brass tray, and triggers the battery powered alarm bell located in the base. The alarm would continue to sound until the tablet was removed. A wheel and pinion pair are missing from the outside of the back plate of the movement. These take power from the center arbor and transmit it to the contrate wheel which rotates the slotted disc within the urn. Lot comes with booklet of information about this type of clock. No memoranda discs are included. Small bin that catches the dics is incomplete.
