Headstock

Speeds

Eight (8) or sixteen (16) spindle speeds obtained through nine (9) .'
or thirteen (13) accurately cut spur gears shaved to a true involute
form concentric with pitch line and operated on heat treated
multiple spline shafts by three or four levers at front of headstock.

Increased or decreased spindle speeds can be obtained by changing
overhead drive or motor speeds. Construction suitable for high
spindle speeds to 1500 R.P.M. and for use with Tungsten Carbide
cutting tools.

Materials

Gears are chrome molybdenum S.A.E. 4150 electric furnace steel
heat treated and hardened to Rockwell C52-55.
Initial drive shaft is heat treated high manganese steel, inter-
mediate shaft heat treated nickel chromium steel.
Spindle forging S.A.E. 6140 Chrome Vanadium alloy steel heat
treated and hardened to Rockwell C36-4,o; spindle nose hardened
to Rockwell C55-5S.

Bearings

Anti-friction bearings used throughout headstock, end works and
quick change gear mechanism-illustrated in line drawing.

Clutch and Brake

A self contained unit with bracket supporting initial shaft on
outer end, unit securely bolted to headstock. Clutch and brake
control levers mounted on apron and directly under headstock.
Clutch is easily adjusted by removing guard on end of initial
shaft and adjusting lock and index collar.

Lubrication

Combined pump and splash system.

automatically pumped through filters. Sight oil level gauge

and drain plug provided.

Gear Finishing

Below is shown closeup view of spur gear being

shaved on Fellows Gear Finishing Machine.

End Gears

End gears are mounted on anti-friction bearings with Alernite
system of lubrication and lower gears run in bath of oil with
sight oil level gauge.

Spindle Bearings

Spindle bearings are TIMKEN "zero" precision type; four
bearing mounting, thrust adjustment taken on two front bear-
ings, rear bearings mounted in floating sleeve to compensate
for slight variations in spindle and housing resulting' f.)'om
temperature changes. Phantom drawing below clearly illus-
trates. Both front and rear bearings mounted in solid housings
eliminating cap construction. - -

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 le adscrew at the
same time.

Leadscrew'Reverse

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.

Mechanism

Quick Change Gear Mechanism

A self contained unit rigidly bolted and dowelled 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 "one shot" system for sliding yoke
provides lubrication for all bearings.

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 micrometeireading.

Tailstock

Massive two bolt type with lateral adjustment for taper turning.
Body of tail stock 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.

Taper Attachment

Carriage type arranged to travel with the car-

riage. Attachment is of the telescopic type
and does not interfere with the in and out
movement of the cross feed screw. One end of
slide graduated in taper inches per foot, the
other end in degrees. Micrometer screw tor
adj listing and suitable clamping bolts pro-
vided. Capacity is 3" or 15° included angle.
Turns tapers 18" in length at one setting.
Right or left hand tapers can be turned.

Micrometer Bed Stop

Attaches to front V of bed, with indexing dial gradu-

ated in thousandths. Valuable for accurately feeding

carriage to pre-determined depths.

Collet Attachment

Lever operated type having capacity to Iy,(" diameter, and with the push rod con-
struction similar to a hand screw machine. The operating lever is mounted directly
over the headstock, permitting easy operation. Lever with end guard casting is always
left in position when removing closer unit at spindle nose,

For long bed lathes and for shaft work this attach-

to carriage and easily removable. (Casting heat
treated aluminum.)

Self Contained Motor Drive

(Flat or "V" Belt and Chain Connected)

Motor is mounted in cabinet leg on hinged bracket
with screw adjustment for proper belt or chain ten-
sion. Motor is readily accessible for lubrication and
repair and belt or chain is completely enclosed by re-
movable guard.

Motors recommended 3, 5 or 7~ H.P., 1200 R.P.M.
Latter size is recommended with chain drive for heavy
duty. 1800 R.P.M. motors are recommended for use

with Tungsten Carbide steels and for high spindle
speeds to 1500 RP.M.

On belt drives (either flat or "V") belt motors should
not run faster than 1200 R.P.M. For high speeds
chain drive should be used. Where chain drives are

used with 1800 R.P.M. motor armature shaft should

not be larger than 1

control is required if reverse to spindle is desired.
