A meeting was held of the Technical Staff at the Clan Foundry on 9.7.41, at which the following were present:- Mr. Rm{William Robotham - Chief Engineer}/CRS. Jnr.{Charles L. Jenner} Rm{William Robotham - Chief Engineer}/RWS. Rm{William Robotham - Chief Engineer}/Col. Rm{William Robotham - Chief Engineer}/JES. Rm{William Robotham - Chief Engineer}/HC. Rm{William Robotham - Chief Engineer}/PJH. Rm{William Robotham - Chief Engineer}/SL. Rm{William Robotham - Chief Engineer}/GR.{George Ratcliffe} EV{Ivan Evernden - coachwork}/JD.{J. Draper - Frames} Rm{William Robotham - Chief Engineer}/GC. Rm{William Robotham - Chief Engineer}/SAS. Rm{William Robotham - Chief Engineer}/Clm.{D. D. Clapham} Rm{William Robotham - Chief Engineer}/Fred Hallam. The contents in Rm.{William Robotham - Chief Engineer}1/SF.6.7.41 were taken as a basis for discussion. 1. Running After Switching Off. It was pointed out that this was still the only undesirable feature connected with the high power engine. O.S.V. with a fair amount of carbon in it, would continue to run for a minute after switching off if the hand throttle was left open. The 4-cyl. 75 mm. power engine was much better and in fact, very nearly passable. It still, however, showed the same tendency on a recent run when the throttle stuck open. Rm{William Robotham - Chief Engineer}/TS. reported that he had some exhaust valves with larger stems available, and after these have been tried, they will be completed to the Vauxhall type of sodium cooled valve. He has also got a tined water spray to put on the exhaust valve stems. It was emphasised that as soon as R.60 No.2 got on the test bed, these features should be tested before endurance was run. Three other features which will be fitted to this engine will be lightened type split skirt pistons, Vandervell tri-metal big end bearings and a light fan pulley. 2. Propeller Shaft Extensions. It was generally agreed that we should never get such a smooth motor car with a split propeller shaft as we should with a single piece shaft. The only way to get the single piece shaft without introducing a tunnel in the floor boards, is to have a long extension on the -Continued- | ||
