    Abstract: An angular divider device is described for worktables, toolholder turrets or the like, in which the number of positions of the subdivision is not predetermined and can be of any desired value, even of very small order such as 1.degree. or even less, without the necessity of positions constrained by mechanical arresting devices such as slots and associated latches, the exactness of the position achieved being determined by the coupling of basic fixed and movable crown gear wheels. The disengagement, the rotation and the succeeding engagement of the movable part, the worktable or toolholder turret, is achieved by the application between the movable part, the fixed part and the movement means, respectively of a brake and of a coupling or clutch which provide alternatively for blocking the movable part in rotation to the fixed part during the phases of disengagement and engagement and for connecting said movable part with the movement means during the rotation phase until the position predetermined by the programme is reached, such position being controlled by a measuring device operating by impulses or the like rotationally connected with said movable part.

    Abstract: The rotatable table of the indexing workpiece supporting apparatus is carried by a vertical shaft which is rotatably mounted within a lower casing. This shaft is connected by bevel gears with a first inner shaft radially disposed within the casing with respect to the vertical shaft, this first inner shaft being in turn connected by interchangeable spur gears with a second inner shaft laterally situated with respect to the vertical shaft. A Geneva cross gearing connects this second inner shaft with a third one disposed in line with respect to the first inner shaft, but on the other side of the vertical shaft. This third shaft is in turn connected with a fourth shaft parallel to the second inner shaft, but situated on the other side of the vertical shaft, and this fourth shaft is driven by means of a vertical worm, the lower end of which projects below the casing to form an inlet shaft, and of a corresponding worm mounted loose on the said fourth shaft, but angularly retained thereon by a torque limiting coupling. The interchangeable gears and the Geneva cross gearing are disposed in opposed lateral recesses of the casing and are easily accessible through removable covers.

    Abstract: An improved machine tool turret assembly includes a turret for holding a plurality of tools. During machining operations the turret is held against rotation by a coupling. Upon operation of the coupling to a disengaged condition by an actuator assembly, a reversible drive assembly is operable to rotate the turret in a selected one of two directions to move a desired tool to an operating position. The coupling is then re-engaged by operation of the actuator assembly. The actuator assembly includes a wedge member which is moved by a cam to effect operation of the coupling between the engaged and disengaged conditions. When the coupling is engaged, a spring applies a biasing force to the wedge member to thereby urge surfaces of the coupling together with a constant clamping force.

    Abstract: A MACHINE TOOL INCLUDES A MECHANISM FOR LOCKING AN INDEXIBLE TURRET IN A PREDETERMINED POSITION ABOUT AN AXIS OF ROTATION WITH RESPECT TO A SLIDE. THE MECHANISM INCLUDES FIRST AND SECOND COUPLING MEMBERS ADJACENTLY LOCATED AND WHICH ARE MOVED RELATIVELY UPON INDEXING OF THE TURRET. A THIRD COUPLING MEMBER IS LOCATED ADJACENT THE FIRST AND SECOND COUPLING MEMBERS AND IS OPERABLE TO PREVENT RELATIVE MOVEMENT OF THE FIRST AND SECEND COUPLING MEMBERS BY SIMULTANEOUSLY ENGAGING THE FIRST AND SECOND COUPLING MEMBERS TO THEREBY SIMULTANEOUSLY POSITION AND LOCK THE TURRET. ROTATION, RELEASE AND LOCKING OF THE TURRET IS AFFECTED WITHOUT AXIAL MOVEMENT OF THE TURRET.
