| TO BY.{R.W. Bailey - Chief Engineer} FROM DA.{Bernard Day - Chassis Design} c. to GJ. c. to WAH. c. to HS.{Lord Ernest Hives - Chair} 40/50 - SPARE WHEEL CARRIER. X3633 We send herewith N.sch. 1409., shewing the spare wheel carrier on the side arranged as we believe suitable for all types of steering. We have consulted the coachbuilders in the matter of the position, and though we have not been able to quite give them what they ask, we believe that what we have done will suit them, and we shall give you further information later if necessary. In the meanwhile we should like you to make the experimental sets. In this arrangement a wheel is carried on both sides of the car. We have chosen one drilling position only and there are two complete carriers making use of one base forging and two tubes the latter of which differs only in the bending. In this way the A.{Mr Adams} & B. type offside carrier becomes C. & D.{John DeLooze - Company Secretary} type near side carrier, and vice versa. We believe that this scheme is the one that will be finally approved, but Mr. Royce also wishes us to send you the alternative, in which the tube is kept straight and the bracket is set over, involving 2 brackets and 1 tube shewn on N.sch. 1433. If Derby have any special preference for either of these methods we would like them to let us know. It will of course be noticed that we are doing away with the oil tank and the wheel is turned round with the dished side to the outside. DA.{Bernard Day - Chassis Design} (Handwritten note on left margin): Since writing the above we have decided not to try N.scheme 1433. | ||
