| c. to EFC. X6096 BY/Cgh{W Clough}21/G.22.3.27. BATTERY IGNITION. X7590 We send you herewith blueprint of D.Sch. 257 showing the radial movement of the centre of the radius of the block on the offset contact breaker rocker, as per LeC. 2380, from which it will be seen that although the average rate of lift is greater than with our present standard rocker the speed at the point of break does not appear to be any greater. We have, however, instructed the offset rocker, but we thought this diagram might be of interest to you. BY/Cgh.{W Clough} | ||
