| -3- R.R. 235 a (400 T) S.C. 532. 15-2-16 G.{Mr Griffiths - Chief Accountant / Mr Gnapp} 1846. E2/G13.7.18. Contd. The valve chest containing inlet and delivery valves should be part of the gun metal casting forming the cylinder, and should be incorporated in the flange which holds the cylinder to the cast iron base plate. Gauze should be fitted on the oil pump suction inlet, and oil should be supplied from a tank at a head, so as to provide for the priming of the pump. The box form of base plate should be used for collecting the laekage and blow-off oil. A countershaft can be carried on the side of the stanchions, as shown in the sketch, with fast and loose pulleys for a belt drive geared down to the pump, with spur gears of about 1:5 ratio. We believe than an oil pump was in process of design for the i ndicator diagram apparatus which Mr. Clark has in hand. The oil pump described in this memo will now supply that portion of the apparatus. E.{Mr Elliott - Chief Engineer} | ||
