ABSTRACT:
An article-holding turret which is particularly suitable for rotatably conveying large objects. A friction brake is fixed to a pawl plate, and these axially mounted structures are oscillated by a rack and pinion assembly driven from a turret index shuttle. A ratchet and spindle assembly is coaxially mounted on the turret's central shaft, and caused to periodically index through desired angular intervals by a pawl carried on the pawl plate. The forward rotation of the ratchet and spindle assembly is accompanied by a commensurate rotation of the friction brake, thereby minimizing rotational drive forces required during this segment. An auxiliary pawl and bracket assembly prevents retrogression of the ratchet and spindle during the reverse oscillation of the friction brake assembly.
