SWITCHBOX FOR USE WITH TWO-RATE CHARGE SCHEME PROVIDING FOR FULL DYNAMO OUTPUT IN S & T POSITION AS WELL AS IN H S & T POSITION. Origin. The fact that it only is important to reduce the dynamo output when no lighting is used. Experimental Test Report. A switchbox on this type has been fitted to Sg{Arthur F. Sidgreaves - MD}'s car 38-GY. And on preliminary test at Derby operated satisfactorily. Road Test Report. Not yet available. X No. 6016. Drawing No. Part List A Scrap and replace at all costs, including Chassis already delivered to Customers. B Scrap and replace on Chassis in Works. C Scrap present stock and replace on all Chassis not yet handed to test. D Use existing stock Alteration effective on future Chassis. Weight of Old Part. Weight of New Part. Difference per Car.

Wor.{Arthur Wormald - General Works Manager} INITIAL | DATE | REMARKS SG.{Arthur F. Sidgreaves - MD} | 13.5.31. | Agreed Sg.{Arthur F. Sidgreaves - MD} R.{Sir Henry Royce} | 18/1/31 | Agree W.R. Personally I do not think this scheme worth while. WOR.{Arthur Wormald - General Works Manager} | 19.2.31 | Agreed Wor.{Arthur Wormald - General Works Manager} In discussion, I cannot see exactly how it serves the dynamo. C. | 14.1.31. | Agreed C. It does not appear sufficiently to make any practical difference. RG.{Mr Rowledge} | 14.1.31. | Agreed Rg.{Mr Rowledge} also have on Mr. report on my suggestion of the possibility of DA.{Bernard Day - Chassis Design} | 15.1.31. | Agreed Da.{Bernard Day - Chassis Design} maintaining the rate of charge with speed by using another BY.{R.W. Bailey - Chief Engineer} | 13.1.31. | Agreed By.{R.W. Bailey - Chief Engineer} problem of which, probably there is advantage in my suggestion EP.{G. Eric Platford - Chief Quality Engineer} | 16.1.31. | Agreed EP.{G. Eric Platford - Chief Quality Engineer} Should like road test before agreeing. E.{Mr Elliott - Chief Engineer} | 5.5.31. | Agreed AE.
