| To By/RD. from Rm{William Robotham - Chief Engineer}/Wst. c. RHC.{R. H. Coverley - Production Engineer} Rm{William Robotham - Chief Engineer}/Wst.6/AP.19.3.37. BENTLEY TACHOMETER DRIVE. With further reference to your By.4/B.18.3.37., the reports mentioned in the second paragraph had nothing to do with the effect of a breather. It is true the breather parts were instructed to the Experimental Dept., but we are informed that you took the parts as soon as they were made out of the experimental Dept. and conducted tests in the Production Dept. No report has been issued by you on these tests and the procedure by which these parts appeared on Production was most irregular. My assistant informs me that he was only informed in a casual verbal way that these tests were being made and was not called in to supervise the same. With regard to the grease and oil in the tachometer flexible drive, we should like to know how it came about that the A.T.Co. were allowed to put oil in the drive. We certainly did not carry out any tests in the Expl.Dept. and it is fairly obvious that oil would have run down into the dynamo. The real point is oil has always been getting through to the dynamo commutator and we believe it has been aggravated by what has been done, without our sanction, over the last 12 months. We are now carrying out further tests to see what can be done about the whole matter to overcome the trouble as soon as possible. Rm{William Robotham - Chief Engineer}/Wst. | ||
