Your comments:

  • I have an almost identical unit which is driven by a synchronous motor from the 50 Hz mains, making it completely self-contained - it seems to keep pretty good time, at least over a few days.

  • My memory of the programmer unit is when i was @ primary school in the 1970,s/1980,s my janitor had 1 in his office,which had a liquid mercury switch moved round when the c7 Pulsynetic master clock sent out a pulse every 30 seconds to keep correct time and for the bells to ring. My secondary school had 1 also,they were taking out the schools and replaced with electronic digital units. I would like to see 1 of the gent of Leicester timer,s again perhaps a museum, the 1 you have.

  • I have installed these units they were part of the Gent of Leicester Pulsynetic Master and Slave clock system. They were often used to ring period bells in schools and equally important sound factory hooters for breaks and stop and start times. The master clock known as a C7 Transmitter was an electric pendulum clock sending pulses out every thirty seconds all devices were wired in series. I installed these in the 1960's while an apprentice with the Reliance Telephone Co. Ltd (GEC). The system also incorporated time recorders to stamp workers cards these however had converters to pulse every minute. This mechanism was part of the C7 Master Clock.
