A paint pump and cart having a movable carriage to enable tilting of the paint pump secured to the carriage via a pivot mechanism without tilting the remainder of cart. A latching mechanism having a spring biased pin received in one of a pair of apertures provides selective retention of the carriage in an operating or loading position and the latching mechanism is operable to release the carriage to move between the operating and loading positions.

A connector assembly suitable for use with armored cables. The connector assembly includes a sleeve that is received over and connected to an end of an armored cable. The conductors of the armored cable are connected to a contact holder that is received within the sleeve. A jacket is molded over the sleeve and a portion of the armored cable. A slip ring placed around the sleeve between the molded jacket and a flange of the sleeve secures a coupling nut thereover. The coupling nut secures mating portions of the connector assembly to one another so as to create a conductive pathway across the connector assembly.

Electrostatic spray gun

The invention includes an electrically isolated electrically less-conductive component fluid-flow course and an electrically-grounded electrically more-conductive component fluid-flow course. The electrically more-conductive component fluid-flow course may be additionally electrically isolated at the preference of an operator. The invention includes an electrostatic spray gun a mixer positioned proximal to the electrostatic spray gun, and a first conduit which holds alternating segments of electrically more-conductive component and electrically less-conductive component. The alternating segments function in series to additively provide a combined resistance which electrically blocks the high-voltage potential generated at the electrostatic spray gun. This, in turn, effectively isolates the electrically more-conductive component fluid-flow course and electrically less-conductive fluid-flow course from the high-voltage potentials, which significantly improves the safety of an electrostatic spray gun used with water-based paints, while simultaneously permitting the use of a standard color change system.
