The turret locking bolt is placed at the frontend of the slide directly under the cutting tool, and works inhardened and ground taper bushings let into the solid construction has been adopted as giving the most rigid toolsupport, the pressure of the cut being downward, resulting ina support which is practically solid. The cross slide moves ona narrow dove-tail guide with a gib for taking up wear, and TURRET BORING, FORMING AND TURNING LATHE. THE SLIDE TOOL. has hand and power cross feed in both directions, with largemicrometer dial. Independent micrometer stops are providedfor each tool on the turret. These stops are convenient to theoperator; they can be used in any combination desired, and arearranged to trip the automatic feed. A very rigid stop is usedto locate the turret in its central position, all movement of thecross slide being from tne center out. Power feed is providedfor both the cross and longitudinal movement of the is of the geared type, giving four changes, which are in- As an example of a remarkably efficient turret boring, form-ing and turning lathe, the new machine by the W. P. DavisMachine Co., of Rochester, New York, claims particular atten-tion. It embodies many interesting features and finely wroughtdetails which easily place it in the front rank of the prominentmachine tools of the year. This lathe has a geared friction head and has positive drivewith the back gears. The triple gear meshe
