X328 DY.{F R Danby} c. E.{Mr Elliott - Chief Engineer} Hs.{Lord Ernest Hives - Chair} Da.{Bernard Day - Chassis Design} FHC. c. E.{Mr Elliott - Chief Engineer} HDY.{William Hardy}1/HP.12.11.35. Gearbox Phantom 3. Lubrication of 2nd speed, 3rd speed, and spigot bushes. We send herewith N. Sch's 4657,4658,4685, which show respectively a gear pump and a trough and scoop for lubricating these bushes. A scoop to N.Sch.4668 has been tried and found to work sufficiently well so that for the present the more complicated gear pump scheme should not be detailed. N.Sch's 4690 and 4691 modify N.Sch.4685 in some respects and where this occurs the former schemes must be worked to. HDY.{William Hardy} | ||
