| R.{Sir Henry Royce} Wor.{Arthur Wormald - General Works Manager} Hs.{Lord Ernest Hives - Chair} X7772 BY8/G.18.2.29. LEFT HAND SS.{S. Smith} VALVE TAPPET MECHANISM. Referring to E2/M9.2.29. which gives a series of proposals for making the left hand American engine based on R5/M3.2.29., it has been decided that No.1 scheme meets our requirements most fully. We have gone carefully into the question of clearance between the tappet rod and the upper tube, and find that we can increase the tube sufficiently to maintain our present clearance, and at the same time maintain the clearance between the tube and the ports.
