| To RHC.{R. H. Coverley - Production Engineer} from Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} X8005 Hs{Lord Ernest Hives - Chair}/Rm{William Robotham - Chief Engineer}3/LG25.10.27 10-EX - ENGINE SUSPENSION. X8380 The whole object of supporting the engine at 4 points is to ascertain what effect the increased rigidity imparted to the frame would have on the car steering. Will you therefore please make sure that the arrangement : (1) Holds the engine rigidly. (2) Imparts the maximum increased rigidity to the frame. Our own idea was that the forging previously used for the bump with pieces welded across the angle could have been used advantageously.
