Bailey - Chief Engineer} c. to Wor.{Arthur Wormald - General Works Manager} SERVO JAGGERS ON 'INDIA'. X.5370 X. 8370 We have carried out your suggestions of introducing flexibility between the servo operating cams and the shaft engaging the servo. We find that a slight flexibility here will overcome the jaggers and will reduce the tendency for the brakes to snatch on. We think it is desirable to introduce some flexibility in operating the servo both on the Phantom and on the India. We have had quite a number of instances of similar servo jaggers on Phantom cars. We are continuing our tests to prove what is the minimum amount of flexibility which will overcome jaggers. Hs.{Lord Ernest Hives - Chair} | ||
