Bailey - Chief Engineer} c. to Da.{Bernard Day - Chassis Design} c. to Wor.{Arthur Wormald - General Works Manager} X/3596 R3/M3.1.22. GOSHAWK - PETROL LEVEL GAUGE. X.3596 Since we have not got a pressure system on the Goshawk, we do not want a magnetic level gauge, and hence instruments such as the Telegauge are unnecessarily complicated for use on this chassis. It has occurred to me that we could make a very simple and convenient gauge by using a float pivoted in the centre of the tank which by means of a bevel gear drives an inclined shaft and indicating needle. This arrangement allows the dial to be in the position desired on one side of the tank, near to the filler. The needle shaft would be mounted in a fixed inclined tube which forms part of the apparatus and the complete instrument could be detached and withdrawn from the tank through the hole in the inclined facing. The whole looks like a 10/-s job even the few we should require say, 20 per week. MADE AT CROXLEY R.{Sir Henry Royce} [Diagram Labels] CENTRE OF DEPTH BEVEL CENTRE OF TANK | ||
