| X350 R HARDY To EY. from Da.{Bernard Day - Chassis Design} SECRET. Da.{Bernard Day - Chassis Design}7/mr.10.5.35. c. for E.{Mr Elliott - Chief Engineer} Hs.{Lord Ernest Hives - Chair} Hdy.{William Hardy} RHC.{R. H. Coverley - Production Engineer} SpectreCodename for Phantom III - Marles type Steering. Commander Maltravers when last here suggested that Timken type Taper rollers, as used by some of the American users, would prove the best type of bearing for the cam roller. On N. Sch.4296 we shewed along with a ball-bearing scheme, a taper roller arrangement with no cage. N. Sch. 4489 herewith, now shows these rollers with a cage. It is not intended to do anything with it as yet, but it will be available if required. Da.{Bernard Day - Chassis Design} | ||
