ABSTRACT:
A rotating turret (10) having an outer plate (12) with several interchangeable tool (13) posts mounted to an index plate (22). The index plate (22) is mounted to a first axle (23) that extends through a block (24) and rotates on a set of bearings (28) mounted inside the block (24). The index plate (22) provides for rotation of the turret (10) between the several tool (13) positions. The index plate (22) is locked into position by a set of pins (34, 37) that fit into apertures (31) in the index plate. The pins (34, 37) are spring-biased toward the index plate (22) by springs (52, 55, and 58). A handle (16) attaches to a second axle (40) to provide a quick release mechanism. The second axle (40) mechanically engages with the pins (34, 37) and a sliding wedge (49) such that when the handle (16) is rotated the pins (34, 37) are retracted from the index plate (22) against the force of the springs (52, 55, 58).
