Thanks for your comments. The local TV station ran their human interest (snooze button) story Fri. night. As soon as they post the video I'll provide a link for those who want to watch.
I appreciate all of your contributions to the group.
Can anyone tell us why an alarm clock snooze repeats every 9 min. (perhaps 7 min.) rather than 10 min?
Our local news station has asked us this question. I had never even considered it, but thought that it may have a basis in the earliest design of repeating alarms.
Thanks for your help
I have one of these clocks on my bench with the same problem; runs +5min/hr.
Obviously my clock has been hacked. The upper jewel on the balance has been replaced with a brass bushing and there is solder under the roller jewel table. I have a strong suspicion that the balance spring is...
Thank you all for your input.
The existing suspension spring was broken. We opted for a more familiar repair; A new suspension spring/leader with a hook just below the crutch, and a loop on the top of the pendulum stick.
FYI, the rating nut is on the bottom of the bob.
The attached photo shows a pendulum/leader assembly which I believe has been modified and is incorrect. The Movement is a Welch 2 spring time only club foot escapement. Notice that there is no way to hook the pendulum, except at the suspension post. The leader/susp. sp. are permanently connected...
Here is a picture of a Corum watch that I would like to know more about.
I have searched the internet to little avail. Even the Corum website http://www.corum.ch/dev_0206/index.html offers little. The following is what I do know:
It is automatic, has a stainless steel case and gold dial...
Magnetism... The "U" shaped rotor did not have sufficient magnetic strength so I re-magnetized it by wrapping it about 30 times with .017 " copper wire (the enamle coated kind used to make coils and magnets) and briefly connecting it to a 12vdc car battery.
I'm afraid I don't have the experience to send you measurements, but I do have an old E. Howard catalog from which I could copy the page with side views of this clock.
Just let me know if this would be helpful.
Thank you for your insight. I would appreciate any copies of pictures that you...
We are restoring a small E Howard tower clock that has been converted to electric and is missing original parts. We want to restore it to original condition and would like to find drawings for the missing parts. Can anyone help?
Dimensions are approx: 28"L x 11"W x 22"H
Thank you for your help and time. I have not solved the sangamo problem yet. Your information is helpfull, by comparison. Can you tell me the ohms measured across your motor coil?
I have also begun to wonder if the motor bushing was designed to be loose, and that my repair, to tighten it, is...
I have a Sangamo electric synchronous motor that I am rebuilding
It has the 15 pole starter with "U" shaped magnetic rotor and bumper pad attached to the copper/tin cup rotor with pinion gear. It was working poorly before I resolved a bad bushing problem. Now it runs worse.
The rotor spins...
I will be visiting Corpus Christi, San Antonio, McAllen, and Brownsville Texas next week. Does anybody know of any interesting clock sites or repair shops that they can recommend for me to visit while there?
