| TO E.J. FROM R.{Sir Henry Royce} Copy to - S.J. " HS.{Lord Ernest Hives - Chair} to E.{Mr Elliott - Chief Engineer} In response to your M.{Mr Moon / Mr Moore} BJ2/H24524. I had the impression that I had dealt with most of these matters, but the following are my opinions however:- (1) WIRE WHEELS - RUDGE WHITWORTH X421 BY.{R.W. Bailey - Chief Engineer} objects at present on certain grounds to these wheels. I suggest that further tests should be made, and that a sample should be sent to WW. (2) BEVEL PINIONS & WHEELS FITTED TO FIRST 220. OF 20.HP.SERIES. X4247 X4569 There appears to me to be no reason for a desperate policy, and I suggest that we only change these gears whenever the cars come into the Works for overhaul. (3) SHORTER GEAR LEVER. X3926 I quite agree to the use of a shorter gear lever on the 40/50 as standard. (4) 20.HP. FOOT BRAKE. X4255 I do not think this can be improved as regards design. It is now of the best proportions possible, and is only defective in performance if there is something wrong with the brake, such as (1) adjustment, (2) bedding of the shoes, (3) materials of the brake surfaces, or (4) oil on the brake. The standard 20.HP. brake in the normal condition is more powerful than the 40/50. If wrong it is a production and maintenance matter to put right. Our own experience has been most satisfactory. HS.{Lord Ernest Hives - Chair} will say if the above is incorrect according to his views. R.{Sir Henry Royce} | ||
