| X228 BY.{R.W. Bailey - Chief Engineer} FROM HDY.{William Hardy} HDY{William Hardy}1/M1.10.32. C. to SG.{Arthur F. Sidgreaves - MD} MOR. E.{Mr Elliott - Chief Engineer} DA.{Bernard Day - Chassis Design} HS.{Lord Ernest Hives - Chair} BENSPORT GEARBOX. We send herewith N.schs 3519/20/21/22., which shew most of the Bensport gearbox. N.sch.3519 has not been appreciably altered since a print was sent to Derby last Saturday. It will be seen that there is no spigot between the halves of the box, and that their alignment is entirely dependent on two taper bolts. Our other synchro mesh boxes have spigots, but examination will shew that they are just as much dependent on the soundness of the dowelling as is the new box for the Bensport. HDY.{William Hardy} | ||
