I recently acquired a Seth Thomas Ships Bell clock in the traditional round brass case with hinged door. The dial and movement are both marked Seth Thomas. Pictures of the movement (front and back) are attached. The movement is a platform escapement and while there is a mostly traditional strike train, there is a set of contacts on the count wheel.
I do not seem to be able to identify this movement but i need to find or fabricate a chiming mechanism for the clock. All I have is what you see.
Any help would be greatly appreciated.
Thanks,

Hi, just a guess but could this be a zig-zag course clock ?

Bruce,
Thanks for the post. The count wheel is set up for traditional ship's watch (1 through 8 bells and repeat). The actuation mechanism is also typical half hour and hour strike. For whatever reason, there are electrical contacts that would actuate bells (maybe remotely). There is no place for a bell on this mechanism. I was hoping there was a power supply and chime generating attachment.

perhaps the mechanism, instead of striking, sends an electric impulse every 30 minutes to alter course and when finished manually is closed down ?

Good afternoon, Calc!

There is currently a listing on a famous auction site for an old advertisement for Chelsea. In it, there is listed a remote bell. According to the ad, the clapper (or "tongue") of the bell is free, so that it can be rung as needed manually, but there is an electrical connection from the clock to the bell to ring the bell for ship's time.

Might be that this is something similar.

Best regards!

Thank you for your feedback. This is definitely not a zig-zag clock. The clock has a traditional striking train. The count wheel on the back of the movement that actuates the electrical contact is set up to actuate the contact and count the traditional ship bell sequence. I am missing the portion that the electrical contact actuates or deactivates

I have moved this thread to the Electrical Horology forum to see if additional answers might be forthcoming.

I would think that there was only an external bell, driven by an electromagnet. You could use a battery and an electric door gong for testing.

Thanks, I am hoping I can find someone with the same clock to see what the "attachment" looks like.
