| To BY.{R.W. Bailey - Chief Engineer} from DA.{Bernard Day - Chassis Design} c. to BJ. Hs.{Lord Ernest Hives - Chair} X5240 DA{Bernard Day - Chassis Design}7/M6.1.27. 20 HP. VERTICAL RADIATOR X.5250 X.5420 X.5240 SHUTTERS. Herewith we send N.schs. 2327 and 2337 also 2338 shewing the proposed linkage for the mixture control on the steering column which is required by the fitting of the above shutters. N.sch.2327 is a suggestion for using the bosses already existing on the engine crankcase and cyl. water jacket cover, and it is thought that it would be probably be satisfactory as shewn; since we are not quite sure whether R.{Sir Henry Royce} will like it however we have prepared N.sch.2337/8 shewing an arrgt. with a stationary tube between the ignition and mixture control tubes which involves altering the bosses on the crankcase and cyl. The arrgts. in the steering column will be sent subsequently. We have looked into them sufficiently far to be sure that they can be done. The levers on the bottom of the steering column for both ignition and throttle have had to be lengthened and we have lengthened those on their respective transmission tubes a corresponding amount, so as to keep the ratios the same as now. We have not been able to find a drawing of the controls with the steering column with outside pendulum lever, and so have had to use a drg. of the older type of controls, and checked them off the 20 HP. we have here. We should be glad therefore if you would verify the positions, lengths of lever etc. on this drg. DA.{Bernard Day - Chassis Design} | ||
