| WORM GEARS (Straight type) Written by Mr Nadin on 9th Feb. Handed to T.C. on 12th Feb. Mr Royce said - Another set of worm gears should be de-signed having an extra start in the worm; this may go hand in hand with the reduction in the centres and will probably necessitate a reduction in the pitch of the teeth in the worm wheel.
