| A.{Mr Adams} FROM E.{Mr Elliott - Chief Engineer} C. to BJ. [strikethrough] " HS.{Lord Ernest Hives - Chair} " BY.{R.W. Bailey - Chief Engineer} [strikethrough] ORIGINAL. SECRET. E2/M23.1.29. SS.{S. Smith} DYNAMO DRIVE, & AIR PUMP. X7100 [strikethrough] X7510 We attach herewith a blueprint of LeC. 2631., dealing with a number of points as follows:- (1) LUBRICATION OF DYNAMO DRIVE PINION BUSH. It is suggested this should be carried out with L.P. oil as a supply is closely within reach, and the drawing shews proposed method of applying same. (2) LUBRICATION OF AIR PUMP ECCENTRIC. Having established the correct fit for the eccentric there is no actual complaint of lack of oil but we shew a means of picking up lubricant from the front camshaft bearing which is fed by its own splash collector trough. (3) DYNAMO DRIVE. The drawing shews the application of India 4. dynamo drive to SS.{S. Smith} in which a metal disc internal coupling replaces one of the serrated type. This is not put forward as an immediate alteration but only with a view to providing for the new drive if found desirable. (4) LARGER AIR PUMP. We note HS.{Lord Ernest Hives - Chair} is asking for a more "efficient" air pump. We shew on this drawing how a pump of .250" increased bore can be got in. The original drawing is attached to BY's copy of this memo. ACL Please note E.{Mr Elliott - Chief Engineer} | ||
