| BY.{R.W. Bailey - Chief Engineer} Hs.{Lord Ernest Hives - Chair} from DA.{Bernard Day - Chassis Design} DA{Bernard Day - Chassis Design}3/M19.2.29. c. to SG.{Arthur F. Sidgreaves - MD} +7340 SERRATED UNIVERSAL JOINT. X.7300 SS.{S. Smith} CLUTCH SHAFT. X.7340 X.1457 Herewith we send N.sch.2832 on the righthand side of which we have shewn R's proposal for modification contained in R3/M12.2.29. We shew a separate filler for the shaft and for the rear joint, but we have indicated the combined filler R.{Sir Henry Royce} suggests with a view to it being tried. It appears to us that as these joints are at least as oil-tight as the Mechanic's joints, and have much less movement to make, they should not require more attention than they do, that is to say, they would be practically filled up with oil on erection and should not require any more, so that the principle object of the connection through the shaft is to lubricate the ball bearings in the clutch. Perhaps you could confirm this. On the left-hand side we have indicated how some room could be saved by this proposal, this room ultimately to be used up in shortening the box, though at the moment it has been shewn giving more space for access to the lubricating hole. We do not think that anything should be done with it at the moment. DA.{Bernard Day - Chassis Design} | ||
