When the clutch is out, just as it becomes free, the pedal might work a valve, thus - To operating cylinder. To induction pipe? and admit suction to a cylinder which might throw out the Salerni or similar clutch on the transmission or gearbox side-shaft. So that no more motion or load need be on the clutch pedal. Can we do anything with this idea? It might be worth an English provisional. R.{Sir Henry Royce} | ||
