| To Sg. {Arthur F. Sidgreaves - MD} From Hs. {Lord Ernest Hives - Chair} c. to Wor. {Arthur Wormald - General Works Manager} 5770 Hs. {Lord Ernest Hives - Chair} 2/MJ.13.6.31. We had a conversation with E. {Mr Elliott - Chief Engineer} on the telephone yesterday. The point he raised was that W.E. were considering adopting the 'Japan(Experimental Engine) 3' design of engine, which you will remember was done when R. {Sir Henry Royce} was at Le Canadel(Henry Royce's French residence), instead of going to 'Japan(Experimental Engine) 1'. The essential features where J.3 is different to J.1 is that the engine gears are at the rear of the engine and that there is a double rear bearing for flywheel. Also J.3 was intended to have a larger size of engine. We mentioned to E. {Mr Elliott - Chief Engineer} that we thought the question of retaining the present size of engine should be very carefully considered, because if it was right two or three months ago to increase the size we did not know of anything that had happened to cause us to say that it was now unnecessary to increase the size. E. {Mr Elliott - Chief Engineer} stated the view they had at W.E. was instead of increasing the size of the small car 25 HP. was to decrease the size of the big car. In view of the new proposition you put forward at Derby the other day, the question of relative sizes of cars may have to be reconsidered, but I thought you might be interested to know what W.E. have in mind. Hs. {Lord Ernest Hives - Chair} Att: Copy of note sent to E. {Mr Elliott - Chief Engineer} (Hs. {Lord Ernest Hives - Chair} 1/MJ.13.6.31). | ||
