Threadless nut

A glassware forming machine baffle arm assembly that includes a quick-connect/disconnect arrangement mounting a baffle manifold on a baffle arm, said arrangement includes:

• a baffle arm having an aperture,
• a baffle manifold having a segment extending through said aperture and permitting rotation of said baffle manifold with respect to said baffle arm, wherein said baffle manifold segment includes a stud having a plurality of lugs,
• a threadless nut that includes
• translational retention lugs circumferentially spaced apart, and positionable behind said stud lugs when said threadless nut is coupled to said stud;
• and
• rotational retention lugs circumferentially spaced apart and positioned adjacent to said translational retention lugs, and positionable adjacent to said stud lugs such that said rotational retention lugs axially overlap said stud lugs,
• wherein said translational and rotational retention lugs define seats to receive said stud lugs and define passages circumferentially between said seats to allow passage of said stud lugs, and
• wherein said rotational retention lugs are axially movable with respect to said stud lugs, and are rotatably movable with respect to said stud lugs when said rotational retention lugs have been axially moved with respect to said stud lugs so as to axially clear said stud lugs, and
• a bayonet connection between said threadless nut and said baffle manifold segment.
