| x9450 Ba. c. Hs.{Lord Ernest Hives - Chair} BY17/H.{Arthur M. Hanbury - Head Complaints} 15. 5. 24. E.A.C?III. SIDE STEERING TUBE. Referring to a7/M.{Mr Moon / Mr Moore} 13. 5. 24, we were under the impression that you were in agreement with Hs.{Lord Ernest Hives - Chair} that it was advantageous to obtain 38° on the driver side as well as on the nearside. It was under this impression that BY8/H.9.5.24. was written. As apparently West WitteringHenry Royce's home town, and we assume R, consider that it is better to have a straight side steering tube although it entails a loss of 2° on the lock, we propose to carry on with the twisted Pendulum Lever and the straight Side Steering Tube. In the meantime, you will of course have received a memo from myself, and possibly another one from Hs.{Lord Ernest Hives - Chair} pointing out that the end of the Side Steering with the low pressure springs of 30 lbs initially is unsatisfactory. We would like therefore to have your modified end as quickly as possible or instructions by telegram for us to get out a scheme maintaining your diametral dimensions and increasing the length to enable us to get the necessary spring movement with the increased load. We would like to draw your attention, whilst discussing this issue, to the fact that increasing the length of the Side Steering Tube Spring end, which is of course the Pendulum Lever, pushes the end of the Side Steering Tube into the Brake Rod Connection to the Front Axle, as you will remember this was particularly close in the original design. Further increase will of course cause a foul at this point. We were not trying to convey the impression that a mistake had been made in regard to clearances shown on N. Scheme 1791. and 1707, but were under the impression, as pointed out above, that when you were at Derby it was generally conceded and agreed that it would be better to increase the steering lock on the driver side.
