| Wor{Arthur Wormald - General Works Manager}2/GR.{George Ratcliffe}4.5.33. MATTERS ARISING OUT OF MINUTES OF CONFERENCE-MARCH 9th 1933. CHASSIS. MINUTE 1. J.II. or J.III. Progress generally. LATEST POSITION AT 4.5.33. Self-adjusting tappets. RHC.{R. H. Coverley - Production Engineer}9/BE.3.5.33. states "fitted on test bed engine." Modified front axle also in hand. RHC.{R. H. Coverley - Production Engineer} states "W.S.3704 and 3690 issued for 4° transverse inclination of pivot. This involves modification to existing dies before forgings can be produced. Work, however, is proceeding. MINUTE 2. PEREGRINE GENERALLY. Oil Consumption. Oil Temperature. Petrol Consumption. Peregrine dynamo is held up until we can get the modified crankcase which allows the dynamo to run at lower speeds. 3½-litre Bentley is having preference, and it will be several weeks before we have a Peregrine fitted with the correct dynamo. When definite progress has been made on the above, Hs.{Lord Ernest Hives - Chair} will send the car back to France to continue running. Hs.{Lord Ernest Hives - Chair} states that he considers we have now got a satisfactory carburettor for this car, and the chief problems left are the oil cooler and starter carburettor, and he further states it is inevitable that improvements will be going through all the time, as the Peregrine we are satisfied with to-day we shall not be satisfied with in 3 months' time. E.{Mr Elliott - Chief Engineer} states we have in hand an improved design of the Peregrine carburettor and induction pipe. RHC.{R. H. Coverley - Production Engineer} states that one type of oil cooler has been fitted to the peregrine which consists of a small radiator secured to the front of the cylinder block. An alternative oil cooler which consists of spiral tubes in the centre of the radiator matrix will be complete and ready for test in a week. Switchbox. E.{Mr Elliott - Chief Engineer} states that he is going ahead along the lines indicated by R.{Sir Henry Royce} but keeping the ignition switch | ||
