G.{Mr Griffiths - Chief Accountant / Mr Gnapp} 4. GEARBOX. FREEWHEEL IN SIDESHAFT. ORIGINAL DA{Bernard Day - Chassis Design}1/M23.4.29. X5310 X523 Herewith we send N. scheme 2881. shewing the modifications to the freewheel which R.{Sir Henry Royce} asks for in R1/M13.4.29. We are not quite certain how R.{Sir Henry Royce} intends that the window shall be produced for assembling the spring, but we believe that he intends it to be with the end mill which forms the stop for the freewheel position of the cage. The drilled holes can either be left as this end mill leaves them after forming the recess for the spring, or the cutter can be dipped still further in. We thought that this was a matter for the Production Dept. to choose. We have also increased the diameter of the end mill making the window for the cage projections, and have provided narrow faces on the driving member to control the cage. On examining N. schemes 2767. and 2773. we see that we have not made them quite agree, so we have taken this opportunity to incorporate the dimensions of N. scheme 2773. As we are not quite certain of R's meaning we have also prepared N. scheme 2880. shewing the window for the spring made with a wheel cutter. Unless Derby think that this is much to be preferred from a manufacturing point of view nothing should be done. DA.{Bernard Day - Chassis Design} | ||
