A horizontal shaft, to one end of which there is affixed a tool-carrying turret, is rotatably mounted in a part of the frame of the lathe. The above shaft is parallel to the axis of the spindle of the lathe, such spindle being rotatably mounted in the head stock. The shaft and the turret are reciprocated longitudinally of the axis of the shaft by a longitudinal advancing mechanism, such shaft also being rotated in steps, that is, indexed around its axis by a transverse feeding mechanism. Such transverse feeding mechanism comprises an oscillating arm which is selectively rigidly connected to the shaft carrying the turret; the oscillatable arm is pivotally connected by an articulating means to a driving rod connected to a driving mechanism which is mounted for pivotal movement around a fixed axis which is parallel to the shaft carrying the turret and is spaced from the latter by distance R equal to that at which such axis lies from the axis of the articulating means connecting the outer free extremity of the oscillating arm to the driving rod.
In a turret lathe having a fixed frame, a lathe spindle mounted for rotation on the frame, a tool-carrying turret mounted on a turret-carrying shaft which is parallel to the spindle of the lathe, such shaft being adapted for translational movement along its axis under the action of a longitudinal advancing mechanism and angular displacement around its axis under the action of a transverse advancing mechanism, the improvement wherein the transverse advancing mechanism comprises an oscillating arm which is adapted to be fixedly connected to the turret-carrying shaft, a driving means having a driving rod, the arm being connected at its extremity by an articulating means to the driving rod of the driving means, the driving means being pivotally mounted around a second axis fixed parallel to the axis of the turret-carrying shaft, the second axis being separated from the axis of such shaft by a distance R equal to that which separates it from the axis of the articulating means connecting the free extremity of the oscillating arm to the driving rod.
