OCTOBER 5TH. Speaking on the telephone this afternoon, E.{Mr Elliott - Chief Engineer} discussed the following points :- P.2. PETROL PUMP He pointed out that this zas not working well in their opinion, probably because it required a larger air chamber on the suction side. The chamber here should be a good one in order to form some kind of an equaliser, as the pump cannot move the whole column of petrol up and down at every stroke. CRANKSHAFT BALANCE WEIGHT. 20/25 HP. E.{Mr Elliott - Chief Engineer} considers that there is some doubt as to out going on with R's 8-weight scheme, as apparently R.{Sir Henry Royce} is still strongly in favour of the Chrysler. We pointed out to E.{Mr Elliott - Chief Engineer} that we could not get the balance weight on existing cranks, as although his drawing was based on the forging drawing from which the cranks are made, when we measured up a number we found that there was much less material available. We are sending to E.{Mr Elliott - Chief Engineer} this afternoon a copy of RHC{R. H. Coverley - Production Engineer}'s sketch showing the metal available. JAPAN 111. E.{Mr Elliott - Chief Engineer} has promised to let us know what he requires in the way of facings on the engine for the petrol pump, and also the water inlet to the cylinders, and will let us have schemes in the course of a day or so.
