The company was founded by John T Gent in 1872 at Leicester after developing an electric bell.He expanded, making all kinds of electrical apparatus. In 1884 I.H. Parsons joined the firm as an apprentice.
When JT Gent retired in 1894, Parsons and Staveley took over. There are patents for applying electricity to clocks in their names and also they were joined in one with T. J. Murday. AJ Ball, a Plymouth watch and clock maker, joined the company in 1904.
In the same year the company made a master clock but it gave a shock to the pendulum at the impulse and proved unsatisfactory. Ball then devised a means to give the impulse in the manner of a dead beat escapement and this was an immediate success. The patent was taken out in 1904 by Parsons and Ball.
The first clock to be sold was installed at Thornbridge Hall.
By 1907 a simplified form was being made but a further simplification, including moving the escape wheel to one side so that the pendulum could be hung in front of the movement for easy servicing was patented in 1907 and production commenced in 1908. This is the clock that became famous as the C6 (no slave dial) and the C7 (with a slave dial)
This clock was modified constantly during its 70 year production life but still retained almost all the original features.
It was marketed as "the B-P Patent System" until 1912 but in that year the name "Pulsynetic" was registered and used for all items included in the system.
The last C7 had not been dispatched in 1987 when D. J Bird wrote a series of articles in Antiquarian Horology, but I think the end came shortly thereafter.
