Any Idea What This Is? Is It a Clock?

    This looks really interesting. Does anyone know what it is? Why are the numbers on the face backwards?

    At first I thought it might be a Barbershop clock, but the numbers are not reversed. It looks like the hour hand has simply been replaced by a dial, given the orientation of the numbers. If it's purpose built, I don't know what it's for. Was there a pointer ot outer dial cover of any kind?

    I am going to SPECULATE here, since there are few responses. This looks to me like a master clock based on some kind of countdown system. This might have been useful in a school based on start times that fluctuated? There appears to be something in the mechanism under the dial and movement that looks quite a bit like a Telechron rotor. If so, it would indicate that his items might be from the late 1917s to about 1930? Or maybe it was modified then? Wish I could help more, but a really neat clock!!! Have you been able to see if there is a manufacturer stamped on the movement behind the dial?

    I'd need some better photos of the mechanism, but my guess is that this is some sort of home brew self winder. The dial seems to rotate clockwise, and time could be read if a fixed pointer was attached to the case or painted on the glass at a the 12 o'clock position. The chapter ring is divided into five minute intervals. So it's kind of a tape measure dial. What's interesting is that you have small numbers 1-12 on outside of the chapter ring, six hours offset. I suspect that the gadget that's at the six o'clock position is a switch or maybe a mechanical actuator. And that some sort of contact or trigger could be screwed onto the rim of the dial, similar to a Simplex time clock (see photo). The numbers are six hours offset because this actuator is at the bottom of the dial, not the top. What I think happens when this contact is made is that the motor (that is a motor?) rolls up the chain, lifting the weight. Whether this energy is what powers the clock, or whether it operated another mechanism, I don't know.

    That sounds feasible. It's an interesting clock. The ladder chain is involved somehow in that motor mechanism. Is it running? I'd love to see it in action.

    If it's any help, the motor is a Bodine Electric with a right angle gearbox, similar to this model NSE-12RH. The motor probably turns 5000 RPM, and the gearbox gives at least 10:1 reduction. It's 1960's vintage.
