Pivotal nut structures (108) are journalled in the ends of the links and linear passageways (90) are disposed in the rotor parts to be nominally aligned with the nut structures.

A plating and coating process of an outer surface of the vessel assembly is performed and assembling a rubber and a nut with the spout body is performed.

The invention also relates to a locknut for a screw-nut assembly.

A screw and nut drive mechanism.

A ring (92) has dogs (93) which can engage recesses in the working nut to interlock with the nut against relative rotation.

A top nut (51) is coupled to motor (100) which are operable to rotate the nut and screw it onto the stud (16).

A seal (62) is carried by the nut for sealing the interface of the nut (52) and a side (10) of the chamber (14).

A multifaceted nut casing (20) has wedge fit threaded jam nut segments (50) (60) for compressing into engagement on the threads of a bolt as the nut is tightened into a locked position.

The nut (3) fixes the wheel (2) on the hollow shaft (1).

A U-shaped spring (30) has spaced arms (32) which springably engage the opposite axial faces of the nut (24) to confine the nut therebetween.

Tightening of the nut joins together the structural elements.

Pivotal nut structures (108) are journalled in the ends of the links and linear passageways (90) are disposed in the rotor parts to be nominally aligned with the nut structures.

Inclined interior surfaces (200, 210) allow the jam nut segments (50, 60) to expand radially about the central axis of the nut casing (20) when the threaded bolt is forced therethrough.
