Abstract: A contactor and a dangler assembly for particular use in a plating barrel for electro-chemical plating operations. The dangler assembly is comprised of a sheathed electrical conductor having a connector disposed at one end and the contactor disposed at the other end. The contactor is comprised of a generally cylindrical housing and an elongated lag screw. An internal passageway defined by three coaxial bore sections extends between opposed casing outer and inner ends and is dimensioned to closely receive a portion of the length of the sheathed electrical conductor from the cable other end. The side wall of the second or central one of the bore sections is advantageously threaded substantially over the length thereof to enhance conductor retention thereby. Upon insertion of the lag screw into the passageway from the casing inner end, the lag screw shank axially penetrates the electrical conductor to cause radial expansion thereof into close retained engagement by the passageway side wall.

Abstract: A hanger bracket for supporting a rotatable barrel within a fluid treatment tank, which bracket is in turn mounted on a support frame. A metal strip is sealed within the plastic hanger bracket in fluid tight arrangement to strengthen the bracket against bending and twisting. The bracket itself is curved inwardly from its connection to the frame toward its connection with the barrel to compensate for changes in the length of the barrel due to thermal expansion and contraction when the barrel is moved from one environment to another.
