Sidgreaves - MD} WOR.{Arthur Wormald - General Works Manager} HS.{Lord Ernest Hives - Chair} SYNCHRO MESH GEARBOX. 25HP. We send herewith N.sch.3397. shewing further experiments to prevent the top gear coming out. Comparing the Synchormesh box with the standard and assuming the alignment to be good, the former seems to differ from the latter only in respect to the sliding piece, which in the former case has teeth and serrations at one end & a considerable overhanging mass at the other. This scheme would correct this difference. The upper scheme is one suggested by "R" but if it is inconvenient under the circumstances, the lower one could be used.
