A desirable feature is thatwhen either of the feeds or the screw-cutting attachment ofthe carriage is in use the others are all locked. The slotting machine shown above is a 16-in. crank-motionslotter direct driven by a motor through the medium of gearingand clutches. The clutches control the various gear ratiosfor the drive, which may be changed from one to another bymeans of the handle projecting from the gear case. Thisslotter has a crank-driven ram and is equipped with a Whit-worth quick-return motion. The feeds are actuated by alarge cam on the main gear, and always take place at thetop of the stroke. This machine has a 36-in. table, with a36-in. longitudinal and 24-in. cross-feed, and has a circularfeed. The maximum height of
