ABSTRACT:
Apparatus for aiding in the manipulation of a tool by supporting the weight thereof is designed particularly for a resistance welding tool. The apparatus includes an overhead support, a curved bar hanging below the support, a trunnion connected to a lower end of the curved bar and a generally horizontal arm rotatably held by and extending out from the trunnion. In particular, the apparatus includes a bail having a circular frame affixed to an outer end of the generally horizontal arm. The bail has two plates affixed together and rotatably carried by the circular frame. The plates have central openings therein to receive the tool and have holes spaced around the central openings to receive fluid fittings to aid in operating the tool. The plates can have manifolds therein to reduce the number of lines required to operate the tool.
