Abstract (en)
[origin: US4858514A] The assembly comprises a bottom plate mounted to freely rotate with respect to a stationary base plate and carrying the saddle frame structure for a gun barrel. A gear unit includes drivable gear mechanism for drivingly rotating the bottom plate with respect to the stationary base plate. A coupling mechanism includes a device for operatively engaging the drivable gear mechanism to rotate the bottom plate member with respect to the stationary base plate. The coupling mechanism includes a gear engaging mechanism movable between a disengaged position in which the drivable gear mechanism is not operatively engaged so that the bottom plate is in a freely rotatable condition and an engaged position in which the gear mechanism is effecitve to rotate the bottom plate with respect to the stationary base plate. In the disengaged position, free rotation of the bottom plate with respect to the stationary base plate may be made in a simple and quick manner via an actuating device.
