Carriage power-feed drive gears

A single full-length, hinge-open guard covered the drive belt, carriage-drive gears and backgear

The  0.5 h.p. , 1500 r.p.m. 1-phase motor was bolted to a pivoted plate. The mechanism was crude: slackening the belt to change speeds required the loosening an Allen screw to allow a push-rod, sitting in a hole bored in the front elevating bar, to be moved upwards allowing the plate to be lifted

Power feed rates totalled six: 0.09, 0.14, 0.18, 1.0, 1.5 and 2.0 mm per spindle revolution.

The carriage-feed gearbox also contained a lever-operated dog clutch that, once the gear train was in motion, allowed the drive to be flicked into and out of mesh. Note the all-bronze construction of the clutch-operation mechanism

The end of the leadscrew was fitted with a usefully- large handwheel and micrometer dial. Note the use of bronze for the smallest gear
