    This is another inheritance from my grandfather. It appears to be some sort of testing device/clock. As you can see from the attached photos, it is mounted on an oak box, with a slide-out bottom. There are several shaped metal pieces, a piece of wood with a metal wrap, and an envelope enclosed with “special” bulbs inside. There is a dual-lead cord that has a bob on the end with a button that can be depressed on the end. I believe the bulbs can be screwed into sockets that are internally mounted on either side of the clock, as the thread pattern appears to be the same. I’ve yet to open the clock part up to see what’s inside that part.

    Does anyone know what this might be, or what the purpose of it is?

    Please see the attached photos for more detail.

    Indeed, very curious. I don't see where the bulbs come out of the case - are they meant to light the face up when the circuit is completed (ie, the button you mention is depressed)? Perhaps it is a timer.

    Isaac, that’s what I’m thinking. But what is the significance of the clock? I’ll need to remove the screws and pull the dial to see what’s inside. There are three screws on the outer part of the case, and two of them are inaccessible so it must be that the front has to be removed to access the bulb sockets. I can’t imagine there’s much room inside to replace those bulbs!

    ...and what would be the power source to light the bulbs??

    That looks like an old "ceiling clock" or shadow or projection clock. Batteries would go in the back and usually there was a sort of projector that went over the clock, pressing the button on the cord would project the time on the ceiling Eveready marketed some in the early 1900s

    That makes sense, Dan. Thank you! Any idea what size batteries and how they would be installed?

    I removed the trim ring (for lack of a better term) from in front of the dial. The hands don’t seem to want to budge, and I’m afraid to put too much pressure on them to remove them. I also found a penciled “43” inside the bottom of the box. I’m now even more intrigued!

    Oh how I wish I had the proper battery and the mirror and lens assembly to see how this clock is supposed to work!

    Those are probably just flashlight bulbs and run on two batteries. Maybe 6 volts. The intensity of the light will determine which.

    The hands are set with that little knob in the center of the back. The larger crank is for winding the clock. I think it is possible that this is a night clock with a dial that could be illuminated by pushing the electric button to read the time. This clock would likely be standing on a night stand next to the bed.

    Yes, but my comment was about trying to remove the hands to access the bulbs inside the clock. They aren't budging and I don't want to force them so I am leaving them alone. I'm going to rig up some batteries to test the bulbs and hope for the best. ;)
