James Cottrell
No. 51. Frame, with unique driving mechanism. Invented by James Cottrell, model maker, 168 Upper Kennington Lane, London, S.E., and William Headley, engineer, 63 Drummond Street. Patent No. 23537: date of application, 4th December, 1894.
The object in view appears to have been to make the descending pedal travel at a slower speed than the ascending pedal, thus prolonging the period occupied by the power stroke and compelling the rising pedal to travel more quickly during the idle portion of its circle of travel. The claims of the inventors cannot be ascertained with any degree of accuracy, as the patent was not completed. Note the neat brazed-up seat-stays. Weight of frame, with chain-wheel and cranks, 12 lbs. Purchased from the executors of the inventor.[1]
