The turret cross slide is made very compact. The sliding tool block is closely fitted and gibbed to the base, which is bolted securely to the turret. A long lever and a small pinion furnish means for feeding the cross-slide tools. The sliding surface is so close to the work that its slight necessary amount of looseness is never greater at the tool point.
This slide is used as a cut-off, also for holding broad tool, especially when the latter is to be used near the outer end of a long and slender piece. For such broad tool work on a slender shaft a supporting bushing is fitted to the hole in upright.
The tool holder furnishes convenient means for holding drill chucks, reamers, taps, etc.
The only Flat Turret Lathe.
The only turret lathe having cross-sliding head.
The only turret gibbed at the outer edge.
The only turret having locking pin directly under the working tool.
The only turret slide having double stops for each position of the turret.
The only single-drive turret lathe.
The only turret lathe in which all speeds and feeds are instantly obtainable.
The only practical drive for either electric or countershaft drive.
The only machine with universal outfit of tools for either bar or chucking work.
No cross slide between turret and work; hence the tools may be made much shorter and stiffer than where it is necessary to over-reach an intermediate cross slide or carriage.
Seven of the twelve turret stops may be used for one of the tools.
Turret stops operate in either direction.
Feeding and stop mechanism accurately measure the pressure with which the turret slide is brought against the positive stop, thus insuring accurate shoulder work.
No troublesome oil pipe and no swing joints.
All spindle driving gears, etc., partially submerged in oil.
All bearings hung to insure perfect alignment.
Cover of head conveniently removable. Adjustment of frictions outside of head.
Clutch scheme gives three speeds for each lever: fast at one side; medium at opposite extreme position; and when in middle position, with both fast and medium clutches disengaged, the slow-moving silent ratchet engages and carries it along, giving the third speed.
Turret turns automatically to the position desired, skipping other positions.
Figures that tell. Swing only 12 and 14 inches; turret diameters, 16 and 18 inches; spindle outside diameter, 4 inches.
Lathe rests on three-point bearing. An unsteady or unnatural foundation will not twist the bed.
The only turners having double size turning adjustments.
The only turners in which the tool and back rest may be quickly withdrawn without disturbing the adjustment.
The only turning tools that do not overhang.
The only machine in which the stock stop operates at the back end of travel.
The only turret lathe taking a cut on long work from, instead of toward, the chuck; and this is the only method of turning long work true.
Oil flows in large, slowly moving stream through the turret and hollow frame of the turner that is in working position; not in a little stream, sputtering at high pressure.
Automatic chuck grips any shape of square, round or hexagon up to the spindle capacity.
Double adjustment of turners, combined with double turret stops, greatly reduces total travel of turret slide.
The only turret in which index locking pin for the turret is nearly as far from center of turret as the point of the turning tool. In other machines the slight necessary looseness at turret center and locking pin allows from two to more times the movement at the tool point, which is more than twice the distance from turret center.
No mechanic would expect to get very accurate control by an index wheel one-fourth to one-fifth the diameter of the work. Other turrets are of comparatively small diameter.
Each tool travels the length of its own cut only.
On account of the double adjustment of both turners and turret stops the machine may be interrupted while running on one kind of work, and with the extra stops set for a new piece, it can turn out an entirely different piece without disturbing the adjustment for the first piece; or, if only one extra piece is required, all of the stops may be held out of position without change of adjustment.
