| HS.{Lord Ernest Hives - Chair} ) FROM R.{Sir Henry Royce} (At Le CanadelHenry Royce's French residence.) Copy to WOR.{Arthur Wormald - General Works Manager} ORIGINAL REC'D AT WW. 18.2.29. HYDRAULIC SHOCK DAMPERS. X235/X7520 I agree to high pressure valve drilled with a one sixteenth hole if thought advisable from tests, but not the slotted faces. I quite agree that connecting links would be improved by being fitted with spring loaded ball ends, (i.e. the lighter load) one spring for two balls, spring load in compression, and solid in tension for maximum high pressure forces. [Text next to diagram] Spring need not go all the way- rod or tube. Movement of block limited so that slack limited to slightly more than wear in case of heavy stress. This would be patentable. I believe DA.{Bernard Day - Chassis Design} had this in hand. R.{Sir Henry Royce} | ||
