Wraith II Steering Column. On N.Sch.4789 we showed a very stiff pendulum lever because at that time in certain quarters/there was a belief that rigidity in the rocker shaft and pendulum lever was conducive to the elimination of road shocks on the steering wheel. We understand that this theory was never substantiated and that the converse is true. Since elasticity therefore in the pendulum lever is not a disadvantage we see no reason why the lever should not be reduced in its proportions comparable with our present cars. We send herewith N.Sch.4861 showing a lever of reduced section on which the stress generally is slightly less than that for the 25/30 H.P. and the Bentley, but more than that for Phantom III. The lever is the only portion modified. Ev.{Ivan Evernden - coachwork} Att: N.Sch.4861. | ||
