Figure1.                                                           1a.

This area of the frame shows where a part was mounted. The central hole is threaded with the other two serving as guide holes for mating guide pins located on the part. Since this part was missing I had no idea what function it might have served. Due to its proximity, I suspected that it had something to do with the arbor which extended beyond the frame just below and to the left of the part, Fig. 1a. Since this arbor also had a hole for a taper pin, something clearly was mounted here.  Whatever it was had been also missing.

The arbor could sustain very little torque, so a small wheel, or bevel wheel being used as a lead off for whatever purpose with the mount above perhaps being used to position the lead off shaft was not likely. It could not drive anything without stopping arbor and thereby the clock. Perhaps an indicator dial was mounted with a pointer on the arbor. This would get around the torque issue, but I could not see the purpose for this. The hand would revolve once a minute in one move (or as now being redesigned in four equal equal moves per minute) and always come to rest in the same position.

My only other idea was what follows in the next series of images. I created a mount to closely match the original shadow as seen in Fig. 1a. This was basically a contact switch with the contact leads near the existing extended arbor to which a small cam was mounted. Once a minute the cam would lightly touch the contacts allowing an electrical signal to drive slave clocks. The design of the remontoire is such that the small drag caused by the contact leaves the accuracy unaffected. Indeed one can put a thumb on the wheel completely stopping the remontoire recoil cycle and as long as it is released before the the cycle is normally completed, the power is uninterrupted to the escape wheel. The cleverness and effectiveness of this design deserves respect. The fact that the remontoire also has a one minute cycle nicely fits the design of most common slave clocks.

The only question is really whether the clock was too old at the time of manufacture to have had such a device. I place the age in the 1870's but it could be from late 1860's to 1890's. For this supposition to be correct the clock should be at least the late 1870's. Not being a person familiar with the hobby as it relates to early electrical time pieces I'm not sure. Anyone out there who has any ideas about this? Do you have a better idea of what might have been in its place? If so please email me!
