| contd :- -2- (3) We find that lever E.72459 will foul the top of piston E.72503 when it drops to exhaust from the fully advanced position unless the size of the neck of the rod is accurately machined. Slightly more clearance here would be advisable. (4) As we have not yet got a rig for accurately measuring the rating of the small torsion springs, we have carried out a test on the governor on the car to determine what the springs are actually doing. Attached are the results which will give you the rating, and shew if the springs conform to your original specification. We have O.K'd the conditions you sent, under which the springs have been working. Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} | ||
