| HS{Lord Ernest Hives - Chair}/HM.{Capt. W. Hallam - Head Repairs} FROM R.{Sir Henry Royce} C. to SG.{Arthur F. Sidgreaves - MD} WW. [REDACTED] M1/M30.11.32 CAR WORK - SUSPENSION. We have long agreed that the front wheels ought to be articulated so that gyrostatic forces do not occur. I cannot see any reason to make the rear ones the same. Most of the schemes are very impractical. Dubonnet has done one clever thing - for the particular design he has adopted - in twisting the whole box round the king post, and therefore the deflection of the road springs does not alter the inclination of the pivots, but this is natural to other designs, and I do not think much of the Dubonnet scheme is practical, including the very flexible springing, because of the change of bump clearance with change of load.
