I picked this up recently at an auction. I thought it was interesting from an advertising standpoint, but it also poses a mystery.

There are two pegs coming out of the back of the case. I have no clue as to what they might be for.

any ideas?

The dial

The back of the movement showing the two pegs.

When I took off the back, I found that the pegs connected to nothing at all.

Side view

The winding keys seen in the side view look more like keys for other clocks: kitchen, mantle, etc. where the key is not attached to the movement. They seem to protrude farther than the usual alarm winders; the bulge in the middle of the alarm winder looks very strange. It might be worthwile to lookup the patent number on the dial.

John,
The strange "knob" on the winding key puzzled me also. I have not had any luck with the patent number on the dial. I did however find THIS ebay item.

My guess is that a lever attached to that part of the winding arbor and turned when the alarm went off. The lever would then, I suppose, turn the range off.

HERE is an ad from 1916. Not much information, but it shows a picture of the clock on the stove.

Perhaps the lever striking the pins would shut off the alarm by stopping the unwinding of the spring; that would prevent the alarm from sounding until the spring ran down and driving the neighbors mad. I don't see an alarm shut off on the clock.
