| To hs.{Lord Ernest Hives - Chair} from E.{Mr Elliott - Chief Engineer} c. to CJ. Wor.{Arthur Wormald - General Works Manager} c. to BY.{R.W. Bailey - Chief Engineer} EP.{G. Eric Platford - Chief Quality Engineer} X.4226. E2/M16.6.22. GOSHAWK TAPPET ROLLERS. X.4226. We are anxiously waiting to know if you have yet achieved any improvement in avoiding flats on rollers by use of the 2 schemes proposed namely, rollers with slack in hole as well as slack endways, and rollers of larger diameter. In the event of neither of these schemes being an improvement it will be necessary to alter the design somewhat by using rockers without rollers. E.{Mr Elliott - Chief Engineer} | ||
