Apron
One piece box construction, double bearing type. All gearing
S.A.E. 1045 steel. Quick acting independent levers operate cross
and longitudinal feeds. Clutch adjustment made by removing
guard and adjusting nuts on end of clutch shaft. Interlocking
mechanism prevents engaging feeds and threads at the same time.
Rack pinion S.A.E. 3250 hardened steel. All bearings in apron
anti-friction construction. Gears and bearings automatically
oiled—sec illustration below.

Leadscrew and Feed Rod
Leadscrew is ground S.A.E. 1040 steel mounted in radial ball
bearings, with hardened steel and bronze washers for thrust.
Separate leadscrew and feed rod construction; leadscrew does not
rotate when using feed rod, and vice versa. Safety interlock
prevents engagement of both feed rod and the leadscrew at the
same time.
Leadscrew Reverse Mechanism
Reverse to carriage is furnished for either feeding or threading
without reversing the direction of rotation of lathe spindle. Re
verse lever is located at right hand side of apron and adjustable
stops provide for automatically stopping carriage for feeding or
threading in either direction at any predetermined point.
Quick Change Gear Mechanism
A self contained unit rigidly bolted and dowellcd to front of bed
and providing 49 changes of feeds and threads, see index plate.
Gears are steel accurately cut with shafts mounted on anti-friction
bearings. Reservoir with “
provides lubrication for all bearings.

§S!W3
Cross Feed Screw
S.A.E. 6150 chrome Vanadium steel heat treated to Rockwell
C36-40, with two direction ball thrust. Cross slide is provided
with micrometer chasing stop for regulating depth of cut. This
construction permits withdrawing tool up to approximately three
revolutions of the cross feed screw and running it in again to
stop without changing the micrometer reading.
Tailstock
Massive two bolt type with lateral adjustment for taper turning.
Body of tailstock is offset to permit setting compound rest parallel.-,
to bed. Spindle which is graduated is high manganese steel and
provided with improved type of binder with equalizing action.
One movement forward or back, of lever at top of barrel, locks
or releases spindle without affecting alignment.

Lubrication
Combined pump and splash system. Oil for spindle bearings
automatically pumped through filters. Sight oil level gauge
and drain plug provided.
End Gears
End gears are mounted on anti-friction bearings with Alemitc

All headstock gears are finished by this method
for quiet, efficient operation.
