Abstract: An electroplating barrel holds items to be electroplated while permitting the passage of electroplating solution into and out of the barrel. The solution enters the barrel through small perforations in the sidewalls of the barrel and then is circulated by the rotation of the barrel in an electroplating bath. In this invention the circulation of the electroplating solution, and thus the efficiency of the electroplating process, is increased by directing the flow of the electroplating solution into and out of the barrel through the use of a support rib structure defining perforated sections in the shape of parallelograms. Also, within those parallelogram shaped sections, the utilization of parallel, elongated openings defined by support segments further encourages the multidirectional flow of electroplating solution. The access doors, through the use of an improved locking mechanism also utilize an identical rib support structure with elongated openings.

Abstract: This invention relates to a system and process for electroplating that has plating drums whereby the plating drums are filled, and emptied of parts at each individual plating cell and the parts are cleansed by spraying, wiping and/or drying and whereby only cleansed parts are transported from plating cell to plating cell. This results in less contamination and higher efficiencies in plating.

Abstract: This invention relates to a process and apparatus for electroplating that has an electrolyte continually circulating through a rotating plating barrel along with its parts to be plated by having a nozzle spray means with perforation on an elongated perforated tube that is positioned above the center of a barrel, whereby the spray means barrel is provided with recirculated electrolyte by means of a pump recirculating electrolyte from a plating tank to the elongated perforations while the barrel is rotating, so that the parts are agitated and greater speed and efficiency of the plating process can be achieved.

Abstract: An improved, doorless, horizontal, perforated electroplating barrel which holds objects to be electroplated with cathode danglers when the barrel is rotated in one direction and upon reversal of the rotation of the electroplating barrel, the barrel empties itself. The improvement resides in the method of plating and design of the barrel that brings about an improved deposition of the electrolyte on parts so that when the parts are initially at a distance further removed from the cathode points, the electrical deposition is improved since the parts are caused to move to different zones in the barrel to be more proximately located for electrical contact with one of the cathode points during the plating operation.

Abstract: The invention disclosed is a perforated paddle wheel electroplating barrel divided into a number of spaced apart longitudinal chambers, each chamber having a flexible chain type cathodic contacts in electrical contact with a tubular conductor tube which rotates with the barrel, said conductor tube rotatably and electrically contacts a pair of conductor arms that are connected to an appropriate source of current.

Abstract: An electroplating barrel comprises a rotatable, perforated barrel for holding objects to be electroplated. The barrel defines at least one access aperture for access to its interior, plus means for imposing an electrical potential across electrolyte solution within the barrel. In accordance with this invention the access aperture has aperture-defining edges, the edges occupying planes which are at an acute angle of about 10.degree. to 80.degree. to the plane of the aperture they define. Accordingly, door members shaped to fit each access aperture and defining correspondingly angled edges may close the access aperture without forming significant spaces between the door members and the aperture-defining edges.
