Unusual Revere electric

[Richard H. Whitmore]

Have in my shop unlusual Revere electric with WM and Winchester chimes. Has balance wheel acting as "maintaining power" when AC fails. Chime selector is push-pull through face. Case is gothic steeple 2 front and 2 rear spires of equal hight. Gives appearace of old Philco table top radio. Overhauled and runs too fast. Appears hairspring has been changed and balance wheel is somhow driving motion works eventhough power on. Need info on BPH also. Anybody seen this one?

Hi Richard,
I am confused by your description. A balance with hairspring can't provide a source of "maintaining power". I collect Sangamo electrics and they have a spring which is wound by the electric motor. The spring is always driving the clock. It is a small spring in a barrel that will run the clock for about a day if the electricity goes off. The motor winds the spring in very small increments because a friction pad gradually stops the motor as the spring gets tight. When the spring runs down the friction pad allows the motor to resume winding the spring. The electrical supply to the motor is never turned off. I am not familiar with the Revere design, does it have a small barreled spring in the movement? You have to manage these clocks like a watch. Make sure the hair spring coils are not touching as they expand and contract. This will cause the clock to run fast. Lengthening the hairspring will slow the clock. Make sure the spring is passing through the reg pins. John
