| R.R. 239A (500 T) (S.D. 408. 29-4-17.) Bm. 215611. To Hs.{Lord Ernest Hives - Chair} from R.{Sir Henry Royce} c. to CJ. EFC. By.{R.W. Bailey - Chief Engineer} Wor.{Arthur Wormald - General Works Manager} Magneto Drive - G.11. Swallow, X4327 XX3581 and Neptune. X3582 With respect to the scheme of driving the magneto through the dynamo, we want to know whether the dynamo is going to be effective in preventing the magneto causing the dynamo to over-run and rattle the gearing driving them, should the gearing be fitted with back lash as we hope it will allow. I should like you to make an experiment at once. R.{Sir Henry Royce} | ||
