Bailey - Chief Engineer} [REDACTED] R4/M14.9.32 Copy to Mr. WOR.{Arthur Wormald - General Works Manager} Copy to Mr. CLAREMONT PEREGRINE CLUTCH OPERATION. X4027 With reference to the clutch operation this we believe we have solved fairly well. Contrary to what one would at first expect we have been able to complete a design in which the torsional vibration in the engine is not communicated to the pedal, and neither is the push of the pedal and connecting link communicated to the engine. It has fortunately been noticed that the trouble with the vibrating pedal comes from a vertical direction which we can isolate by carrying the pedal from the frame, and that the axial thrust of the engine from the multiplied pressure of the pedal is in a longitudinal direction and can be coupled to the engine so as to exactly utilise the effect of the pedal on the engine. This idea, which is an extension of our 25HP. scheme, originated with DA.{Bernard Day - Chassis Design} and myself, and should I think be protected with a provisional patent to prevent our being bled by someone else for our own scheme, should they patent it before we sell any cars or otherwise publish it. BY.{R.W. Bailey - Chief Engineer} should decide. R.{Sir Henry Royce} | ||
