| To HS.{Lord Ernest Hives - Chair} & HY.{Tom Haldenby - Plant Engineer} from R.{Sir Henry Royce} -8- R10/G25/11/21 Contd. X4075 (32) CHASSIS WIRING. For the chassis wiring I think we should use a general system of wires in straight metal tubes screwed, bends only split where necessary. I think that a preliminary scheme might be prepared on this in Derby where it is possible to refer directly to an actual chassis, unless you can let me have a chassis down here very soon, which need not for the purpose of usefulness, be up-to-date in every respect. (33) AUTOVAC PETROL FEED. With regard to this item, we are supplying designs for a square tank holding ¾ gallon, having a tower to one side for the Autovac mechanism, no filler, and a needle valve instead of a cock for shutting off the petrol. This drawing was sent to Derby early this week. (34) ENOTS LUBRICATORS. We have sent instructions to Derby for these, or a simpler scheme to be applied all over the chassis. (35) RADIATOR SHUTTERS. We are working on this now and the shutters are being fixed in front of the radiator, and operated directly from a thermostat (Look upon these as an extra) (36) LUGGAGE GRID AND SPARE WHEELS. Mr. Day's department will set out a luggage grid, but this is of second importance compared with some of the other work we are doing at the moment. There is a great problem in finding how we can carry two spare wheels. We are revising the whole subject. (37) FRONT ENGINE SUPPORT. We have just completed the improved scheme for this, which consists of the two side tubes bent round and brazed into a forging which has an oil-less bushing forming a pivot bearing on the starter tube. The brazing does not occur where the tubes are stressed most. This Scheme makes a three point suspension of the unit, therefore reduces the stresses at the same time the front end of the engine is accessible, and the unit can be taken out of the frame without much dismantling.
