Patent #190,951
“Improvements in Clocks and Clock Movements”

Not surprisingly, given the opportunities it offered, Charles Bird Plimpton, BAYKO's inventor, clearly spent much of his early life working in his father's business, J.C. Plimpton & Co. Ltd.

Among other things, they traded in, and even manufactured, watches…

We know that C.B. also spent a brief period working at a clock and watch manufacturer in the United States - probably Kendal, Ohio - possibly with a firm whose products his father's business imported…

On March 9th, 1922, C.B. and his father's business [both are named on the application] made an application, #6923/22, for a patent for “Improvements in Clocks and Clock Movements”. Further amendments were submitted, and this process was completed on November 7th, 1922.

Patent #190,951 was granted on January 4th, 1923.

The full, four page, application is laid out below : -

Oh alright then, you've talked me into it - the patent relates to a general approach to clock design intended to improve the method of securely fastening the clock movement into it's case. This is done in such a way that it can be achieved from the outside, significantly simplifying, and hence speeding up, the clock's final assembly timing - a boon in these days of mass production and the drive for optimised, cost effective operations. My guess is that it would also be popular with the repair shops for the same reason.
