Contents,; Starett dial Test lndicator. No. 196l This Indicator is simple, reliable, easily read and very sensitive. The slightest pressure upon the con- tact point produces a movement of the hand on the dial. The circumference of the d.ial is divided into r z S equal spaces, each one representing a movement of the contact point of one-half thousandth of an inch. One revolution of the hand therefore indicates r - r 6 inch, and two revolutions ,/B inch, which is the capac- ity of the instrument. The dials are figured in two different ways: Style A is marked o, 5, ror 15, etc., to 62fi, the figures donating thousandths, and is most useful in greater forward movement, measuring, index- irg, spacing, etc.; Style B is marked from o to S, % to right and left, and is best for general use. By bringing contact point against the work with just enough pressure to give the hand one full turn, then setting it at o, an opportunity is given for one E CONTACT POINTS FULL SIZE ffi PRICES. lndicator, A or B. with ' three contact points, and twelve safety screws each, $7.00 Tool Post, extra, .50 Surface Gauge sleeve, extra, ,7 5 Extra contact points, each, .l 0 Extra safety screws, per dozen, .l 5 aea Send _fn, free Catalogue -No, rZ D of hi-n.e Mechanical Tools, full revolution of the hand to both right and left of o, showing a rise or drop amount of variation. A most valuable feature is the adjustable dial. By turning dial may be instantly moved to bring the o mark to any point desired in relation to the hand. Each Indicator is fitted with friction joint and removable 3-inch rod, adapting it for use in any position, at the top, bottom or side of work; also with three hardened and ground contact points adapted. for different classes of work. There is also a safety collar to prevent damage from an upward jam or Crowding, and a small, hardened screw' connecting the collar and contact point, with a V groove in the center. This little screw is strong enough to stand all the pressure necessary, but is intended to break under too much strain or side jam, and so prevent greater injury to the instrument. The broken ends are easily removed, and a new screw inserted. The special tool post and sleeve as shown are useful in lathe work. For general work the Indicator is adapted for use with our 9-inch or rz-inch Surface Gauges. On plrrr.., milling machine and in setting up machinery, this tool will be found indispensable when once in the work and the knurled rim the lathe, used. The L. S. Starett Co, Athol, Mass., U.S.A.

SINGLE-HEAD AUTOMATICS are designed for machining castings, forgings, and second-operation screw machine work.
The universal work-holding, turret is adaptable for holding work in chucks, draw-back collets and arbors. The arrangement
of the tool-carrying spindles opposite the work-holding devices allows all operations to be performed simultaneously. All
operations are automatic, except insertion and removal of work, and the provision of an extra or idle chuck permits even
that to be done while tools are working. All machining operations take place in the intervals marked by the automatic
progression of the turret indexing mechanism, the time necessary to complete a piece being measured by the period
required for the longest single operation on it.
DOUBLE-HEAD AUTOMATICS differ from the Single-Head in having two sets of tool-carrying spindles oppositely facing a
common work-holding turret. This arrangement provides for machining both ends of the work at. one time, the result being
accomplished in one- half the time which would be required if each end were finished separately in a Single-Head
Machine.. In the case of the, Single-Head Machine the turret advances and feeds the work against the revolving tools,
while:, in the Double-Head type the revolving tools advance from both sides and perform their operations on each end, of
the work.

rapid production on general brasswork.
Because of the general satisfaction the Fox

Maintaining Uniform
Surface Finish of the Balls
By the method shown above several from
each lot of balls for Hess-Bright Bearings are
carefully studied. Under the microscope that
surface, which to the naked eye appeared
flawless, will occasionally show up to be
comparatively rough, due to deep grinding
marks or pits.
Such balls would be immediately detected in
the final ball inspection by the Hess-Bright
methods and the entire number of similar
balls rejected.
This microscopic study of the ball surfaces
insures to each Hess-Bright Bearing balls of
the highest polish—balls with that flawless
surface which is absolutely necessary for
smooth running, with almost total absence of
wear.
Hess-Bright's Conrad Patents are thoroughly
adjudicated.
