Automatic Memorandum Clock
This type of clock was first patented in 1891 by John Davidson, and some 5 years later he patented the " improved Automatic Memorandum Clock " of which this is one .
The instructions on the clocks lid read:- " Write nature of engagement in pencil on ivorine tablet, then place it in the slot representing the time you wish to be reminded of your engagement; when the
desired time arrives, the tablet will discharge into the tray in front of the clock, and the bell will ring until the tablet is removed from the tray.
All your engagements may be placed in the clock at once or as each engagement is made.
To use in the sick room or Hospital as a reminder of each period when medicine,&c., should be given. If the bell should be considered objectionable, place the small piece of wood ( supplied with the clock) under the tray, then the tablet will discharge into the tray, without ringing the bell."
Some of these clocks had cylinder platforms escapements fitted, this one however is fitted with a pendulum.
The clock stands some 14 inches high and is made of walnut. I've included some pictures of the revolving drum showing the hour and quarter markings with slots for placing the reminder markers.
These clocks are now very collectable
