PCT No. PCT/CA97/00350 Sec. 371 Date Jan. 13, 1998 Sec. 102(e) Date Jan. 13, 1998 PCT Filed May 23, 1997 PCT Pub. No. WO97/46740 PCT Pub. Date Dec. 11, 1997The holding clamp of the invention has a first elongated arm and a second shorter arm both being electrically conducting and interconnected in parallel spaced-apart fashion by a transverse pivotal bracket intermediate their lengths. The first elongated arm is fixedly attached at its upper end to a cathode frame bar and downwardly depends therefrom. A lever pivotally attached to the first arm intermediate the cathode bar and the pivotal bracket engage the upper end of the second arm in clamming fashion to forcibly tilt same between a first limit position, in which the lower ends of the two arms are spaced-apart, and a second limit position, in which the arms lower ends abut one another under the action of coil springs. The lower ends of the arm members form a pair of jaws provided with electrically conducting studs engageable axially to one another, the studs and arms lower ends being otherwise enveloped with a fluid-tight and electrically insulating sleeve, except at the studs outer free ends. Coil springs straddling the two arms between the pivotal bracket and the lever mount bias the jaws forcibly toward one another. An article to be electroplated is to be sandwiched between the electrically conducting studs outer free ends, under bias from the coil springs, to be submerged in an acid solution bath and electroplated therein.
