| To BY.{R.W. Bailey - Chief Engineer} from Hs{Lord Ernest Hives - Chair}/Rn.{Mr Robinson} X8450 Hs{Lord Ernest Hives - Chair}/Rn{Mr Robinson}3/LG25.4.27. HYDRAULIC SHOCK DAMPERS. X235- We find that in a number of cases we require a much greater low pressure loading than we are able to get with the springs available. The strongest spring we have F.5169 gives 90/100 lbs. at the end of a 7.5" lever, and we require 140 to 150 lbs. in the extreme cases. Could you look into the matter, and if it is impossible to fit a spring of this strength at present, alter the piston so that this could be effected. SIDE STEERING TUBE SPRINGS. We have at present only one type of spring for the side steering tube you give with N.sch.2301. We should like springs of 2000/2500 rating to supplement F.76267 for use on special cars such as 10-EX.
