RALEIGH PATENTS FOR CYCLE IMPROVEMENTS
It is not known exactly when Frank Bowden joined the company. However, by scrutinising the patents reproduced below, I can see that the date of the first British patent of the ‘Brake for Cycles’ is 3rd December 1890, and Frank Bowden is not recorded as a witness at the bottom of the patent.
However, on the second patent – ‘Mud guard for velocipedes’ – whose British patent is declared as 20th June 1891, you can see him recorded as a witness.
This does not necessarily reflect the date he joined the company, but it does illustrate his serious involvement by June 1891.
