| To BY.{R.W. Bailey - Chief Engineer} from E.{Mr Elliott - Chief Engineer} c. to CJ. Hs.{Lord Ernest Hives - Chair} 48270 SECRET. E1/M30.6.24. E.A.C.11. ENGINE CONTROLS. X.9840 X8240 X.9140 X8140 We send herewith drawings Nos.Lec.1886/1887/1889., dealing with the alterations to the controlsfor the addition of a throttle governor. You will notice that we no longer require the fine adjustment pick-up gear on the steering side, but that the lever on the steering column is connected to a control tube concentric with the ignition control shaft, enabling us to run a rod forward between the ignition tower on the crankcase for connecting up to the governor through the agency of the usual spring. Would you kindly get out a spring in Derby to suit the new governor on the lines of the 40/50 HP. We have shewn a double lever with 3 positions for hanging on the spring for the purposes of experiment. A further scheme will follow dealing with the alterations on the carburetter side.
