| ORIGINAL TO BY.{R.W. Bailey - Chief Engineer} FROM E.{Mr Elliott - Chief Engineer} SECRET. E1/M22.2.24. Copy to - CJ. HS.{Lord Ernest Hives - Chair} re. E.{Mr Elliott - Chief Engineer} A.{Mr Adams} C. CLUTCH. X9300 X9480 X3259 We send herewith drawing No. LeC. 1836., shewing the driven disc of the EAC. clutch made in ferodo instead of steel. Needless to say with this type of clutch the spring plungers should not be used, but if flexibility were required on the driving surfaces it would have to be introduced in a somewhat different form. A blue print of this drawing has been sent to Mr. Royce and should any alteration be required for the experiment we will let you know. We should be glad if you would please send a blue print of this drawing or the original to Mr. Rowledge for his inspection. E.{Mr Elliott - Chief Engineer} | ||
