These machines mark a distinct advance in Turret Lathe construction. The
introduction of many new features and refinements have made possible the production
of a class of work which for accuracy is beyond that which has been supposed or
known to be obtainable on Turret Lathes. The machines have an exceptionally
wide range and readily accommodate themselves to special tools for work out of the
ordinary.

TAPER TURNING TOOL
Suitable for turning tapers from either bar stock or forgings. Back-rest jaws may
be set to follow or lead the tool as occasion may demand. The cutting tool is directly
controlled by an accurate taper bar for angle, the work produced, therefore, is of a
superior order and is fully equal to that obtained from an engine lathe. The radial
adjustment of the tool slide which permits roughing and finishing cuts is accomplished
through the taper bar-block screw, accurate adjustments being possible by means of the
micrometer dial. In order to produce the required taper it is only necessary to plane
a bar to a taper one-half of that required on the piece to be turned; thus, if the desired
taper is ^ inch to the foot the bar should be planed to i^ inch to the foot. One
taper bar planed to produce tapers ^ inch to the foot (unless otherwise specified) is
furnished with each tool. Made for the i, i^, 2 and 3 -inch machines.

of "V" back-rest holders with two sets of jaws, one large and one small, are
regularly furnished.

TURNTABLL LATHL APPLIANCES AND TOOL5- Continued
Turntable Cut-off and Forming Tool Tool slide is operated by means
of a rack and pinion actuated by long lever which may be clamped to the pinion stud
in any desired position to afford convenience in operation. Adjustable stops determine
the movement of the tool slide. Tools rest on rockers and can be adjusted vertically.
The construction permits the inverting of the rear tool if desired, thus it can be used
without reversing the machine.
Turntable Cut-off and Forming Tool
Bell -mouth Pointing Tool For chamfering the ends of rough rods preparatory
to turning. It is provided with a round shank 2^ inches in diameter. Back-rests, jaws
and cutter are of high-speed steel.

TURNTABLE LATHL APPLIANCL5 AND TOOL5— Continued
Lnd Forming and Pointing Tool For pointing and forming the ends of
finished bars. Back-rests are provided which can be easily reversed for different
diameters. Jaws and cutter are made of high-speed steel.
Self -Opening Die This die has a roughing and finishing attachment which
insures threads of superior accuracy and finish. The I yz -inch capacity is recommended
with this machine, but die-heads with 2 -inch capacity may be furnished if desired.
See page 79 for illustration.
Taper Turning Tool Suitable for turning tapers from either bar stock or forgings.
Back-rest jaws may be set to follow or lead the tool as occasion may demand. Taper
is governed by an accurate taper bar and the work produced, therefore, is of a superior
order and is fully equal to that obtained from an engine lathe. One taper bar, planed
to produce tapers TTg- inch to the foot (unless otherwise specified), is furnished with
each tool.

Taper Turning Tool, with Following and Leading Back-rests
Open Side Turner Is recommended for turning short work above 2^ inches
diameter when back-rest jaws are not required. It is similar in construction to the
universal turner, with the exception that no provision is made for back-resting the work.

W H I
4 X 30-INCH CYLINDRICAL AUTOMATIC SIZING
GRINDER
In the design are embodied many new important improvements which greatly
increase its production capacity and also make possible a greater degree of accuracy.
Automatic Sizing Device A very simple device, very easy to operate,
which, after setting to the required diameter, will automatically grind any number of
pieces to the exact size irrespective of wear of wheel. In operation it controls and
utilizes both the roughing and finishing feeds, thereby obtaining the maximum output.
Back-rest Rigid, Automatic Positive Feeding Type, which automatically
follows up and correctly supports the work without yielding, at a pressure easily
governed to meet any requirement. In action it readily demonstrates its superiority
over either the yielding or hand adjusted type.
Overhead Driving Mechanism Consists of but a tight and loose pulley
countershaft. The other necessary driving parts have been simplified and placed
within easy reach of the operator by being made a part of the machine proper.

These machines are invaluable for work which can be reproduced from a
master form. In gun and sewing machine factories, where they are extensively used,
the process of hand-fitting has been practically eliminated upon parts finished in this
manner. The machines are made with either gear or belt drive. For high speed work
the belt driven machine is recommended, although special high speed gears may be
furnished to meet certain requirements.

ROTARY OIL PUMP5
These pumps are of approved design, made in the most substantial manner and give
excellent results. The Nos. o, 3 and 1 2 are low pressure pumps for use on milling
machines, screw machines, etc.
Special attention is directed to the No. 2, perfectly balanced, high pressure pump.
In the design the usual stuffing box has been eliminated. Bearings are hardened and
ground and, in fact, both design and workmanship ensure the highest possible efficiency
in pump construction. It is used on the gun barrel drilling machines and for similar
purposes where a high pressure oil supply is necessary.

*By the action of the manufacturers of wrought-iron pipe and boiler tubes, at a meeting held in New
York, May 9, 1889, a change in size of actual outside diameter of g-inch pipe was adopted, making the
latter 9.625 instead of 9.688 inches, as given in the table of Briggs' Standard pipe diameters.
