Patent #190,951
"Improvements in Clocks and Clock Movements"

Charles Bird Plimpton 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...

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 : -

I'm afraid if you want an explanation of the patent I'm going to leave you to read it for yourself.

That's about all I can add on this subject I'm afraid...

...except, perhaps, to comment that this application, though very far removed from BAYKO, clearly seems to support those who argue that C.B. Plimpton was the main driver of innovation...

...it looks like he was a natural innovater.
