| X52430 To RG.{Mr Rowledge} from DA.{Bernard Day - Chassis Design} Hs.{Lord Ernest Hives - Chair} c. to BJ. (2fused) DA{Bernard Day - Chassis Design}3/M28.1.27. 20 HP. RADIATOR WITH VERTICAL SHUTTERS - STEERING COLUMN. X.5250 X.5430 X.5240 wish to We/send N.sch.2354 to R.{Sir Henry Royce} as the final drawing of the 20N HP. vertical radiator shutters, and send a print herewith for your agreement or comments. In order to reduce the amount which the Klaxon button towers above the wheel we have suggested slight modifications to the ignition and throttle control levers, consisting of setting the sheet metal part and straightening out the nickel silver castings, which together have the effect of flattening the throttle and ignition controls. In all other respects the arrgt. shewn here follows that existing on the Phantom. There is a question of an anti-rattle device. We are not sure from the information we have here exactly which one is used, and we are obtaining particulars from Derby, but we expect that we shall get it into the dimensions shewn on this drawing. The double nut at the bottom of the stationary control tube was first introduced in order to avoid slotting the conical fitting on the end of the tube. The slotting has been introduced since in Derby, and therefore we suggest there is now no need for the second nut. DA.{Bernard Day - Chassis Design} | ||
