lathe — it is not necessary to remove it for straight turning or facing jobs. Loosening one nut and tightening two others puts taper attachment in operation — there are no parts to remove.

Taper attachment is set by loosening clamp screws at either end of slide, and turning Vernier adjusting screw, as shown at right, until index mark comes to desired position.

Cuts external or internal tapers up to 10" long at one setting — simply reset along bed for longer work. Two easy- to-read sets of graduations show taper both sides of center line, one in degrees, one in inches per foot. Range, right or left, is 15° (3" per foot).

When ordered with lathe, taper attachment is installed at factory. Can be easily installed on current model lathes having chip guard on cross slide.

Lathes not having chip guard on cross slide require a milling cut, drilling and tapping — print furnished.No. 7515 TAPER ATTACHMENT for Clausing 12" pre­cision lathes. ZUSAZ. 40 lb.

The Varidrive Motor pro­vides an infinite number of speeds between 30 and 1400 RPM. All speeds available instantly — dial control on Varidrive is easily accessi­ble through cabinet door. The Varidrive is compact, highest quality construction throughout—an ideal drive for production and general lathe work.

Full cabinet models Nos. 6306, 6307 and 6308 can be supplied with Varidrive. Varidrive must be ordered with lathe and cabinet from the factory — it replaces the standard countershaft drive. Varidrive is available, extra, for single and three phase currents as indicated below.

Atlas motors are powerful, quiet, smooth-running — have large ball bearings — may be operated in any position. Built to exact­ing Atlas standards, their sound design and rugged construction insure long service life at peak motor performance. Switch, cord and plug are not furnished.

The bed is a single, massive, semi-steel iron casting — 7%" wide, 5(4" deep — thickly ribbed and braced. Vee-ways, flat ways and undersides are ground — all eight surfaces align to within .001". The Atlas bed is a rugged precision foundation that maintains alignment of headstock, carriage and tailstock under heavy loads.

Heavy tailstock is accurately machined and hand fitted — a rugged work sup­port. Ram is ground steel — I3io" di­ameter. 5%" long — has long key guide that absorbs heavy torque loads — large coordinate type lock. Ram is graduated 0 to 3" by 16ths. bored for No. 2 Morse taper center. Swing-type wrench, perma­nently attached, controls bed lock. Op­posed screws permit 1" set-over.

Drive is underneath, with spindle pulley mounted "outboard” — replacing belts is a quick, easy job. 8" diameter spindle pul­ley plus dual A-belr drive assure full trans­mission of power. Pulley turns on heavy- duty Oilite bearing.

Lathes with standard motor drive have ball bearing-equipped countershaft that provides 8 speeds between 50 and 1300 RPM — four speeds direct, four back- geared. Convenient shift lever slacks belt for quick belt-position changes.

Varidrive, ordered with cabinet models (see pages 2 and 3), gives an infinite num­ber of speeds between 30 and 1400 RPM. All Varidrive speeds available instantly — dial control on Varidrive is easily access­ible thru cabinet door — remote control is available, extra, when ordered with Varidrive.

Quick-change gear box is enclosed — entire mechanism runs in bath of oil for longer service and smoother operation. Exclusive override clutch prevents tooth damage by assuring proper meshing of stack gears in every thread or feed engagement. Lead screw is %" diameter . . . turns on two Timken tapered roller bearings in gear box to eliminate end play.

Apron is thick, one-piece double-walled — a rugged housing for the gears and clutch. All gears run on ground steel shafts supported by wide bearings in both front and back wall of apron. Gears and shafts run in bath of oil.

Power feeds are engaged by a positive clutch working thru worm and worm gear. Shift knob on face of apron is pushed in and down to set cross feed — pulled out and up for longitudinal feed. Slot in lead screw drives cross and longitudinal feeds — split-nut feed is used for threading only. Built-in safety lock makes it impossible to engage feeds and half nuts at same time.

Saddle bearing surfaces are accurately machined and hand fitted. Heavy plate on each side of saddle bears on bottom of bed ways to prevent lift and twist. Four bed wipers, one at each corner of carriage, clean and oil the ways. Cross slide bridge is wide and deep — a rigid support for the compound rest. Cross slide dovetails are precision ground square with saddle ways.

Top of cross slide, underside of compound rest base, tool post slide ways and top of tool post slide are precision ground. Cross slide and tool post slide have gib-adjustment for take-up. Cross slide is machine graduated 180° — turns complete circle and locks rigidly in any position. Cross slide travel is 9", tool post slide travel is 21/2".

Tool post, ring and rocker are Tool post slot takes 1/?" tool bits

The thick-walled grey-iron headstock is enclosed so reverse gears, front spindle and small back gears can'travel in bath of oil. Back gears are engaged by pulling hand­wheel at rear of spindle and moving back gear lever forward. Spindle turns on large selected Timken tapered roller bearings that assure long accuracy life, permit high spindle-speed work as well as turning at normal speeds. Spindle is forged, precision-ground steel with 1 %" bore and 1" collet capacity. Hardened and ground spindle nose is tapered key-locked type —spindle can be reversed without danger of the chuck’s coming off. Reverse gear lever is conveniently located on headstock.
