Recently my brother-in-law found this clock while digging in an old garage. He asked if I could find out its original use.

Dial with hands and "alarm?"

There are three electrical contacts on the left, lower case.

Bottom of clock has an electric "door bell"

Rear controls have no accomodation to "set" an alarm. I took a quick look at the movement and found a fairly simple balance wheel movement with a set of contacts near the "alarm" dial. The rating lever is pushed all the way to one side--a danger sign.

The rear of the clock with wooden panel removed.

Dick,I wonder if thats an old hotel clock.It looks like it may have been used to provide a wakeup call from the front desk via an electrical impulse.Just a guess.

That clock is very much like a Darche. A small flashlight bulb would screw into the socket at the dial. On the side you would have had a squeeze bulb switch. Depending on which terminal you had the switch attached to (on the side), by closing the circuit with the switch, you could ring the electric bell, or light the dial to be seen at night.

Ad naseum. If it is like a Darche, a dry cell battery would have gone under the base. It would also electrically ring that bell when the alarm went off. I think Darche advertised their bell would "ring for 32 hours non stop". They were very loud.
