Abstract
Abstract A continuous contact plater is disclosed having a pair of opposed belts for grasping and driving contact points through a pair of opposed jaws to be plated by contact on an anode roller, the same describing a helical trace on the roller. A metering roller is provided to adjustably determine the concentration of the plating fluid on the main roller, and a tray is positioned beneath the anode roller to the end that a porous sleeve on the anode roller constantly passes into the electro-plating solution in the tray. Adjustment means are provided to adjust the roller with regard to the contact points between the opposed belts, the latter being fixed with regard to the frame of the unit.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
94 words
A metallic electrical contact element having a discreet convex curvilinear surface portion intended for electrical contact, said surface having a localized conductive electrodeposited contact point thereon, said contact being produced by providing a roller carrying an electrolyte on its periphery for plating said contact, positioning said metal contact element transversely to the axis of the roller with said periphery in tangential engagement with said contact, rotating said roller while passing an electric current between the same and said surface whereby a feather edged conductive electrical contact point is produced on said convex curvilinear surface.
Claim 2
Dependent Claim
94 words
A metallic electrical contact element having a discreet convex curvilinear surface portion intended for electrical contact, said surface having a localized conductive electrodeposited contact point thereon, said contact being produced by providing a roller carrying an electrolyte on its periphery for plating said contact, positioning said metal contact element transversely to the axis of the roller with said periphery in tangential engagement with said contact, rotating said roller while passing an electric current between the same and said surface whereby a feather edged conductive electrical contact point is produced on said convex curvilinear surface.
Claim 3
Dependent Claim
15 words
The metallic electrical contact element of claim 1, in which said contact point is gold.
Claim 4
Dependent Claim
17 words
The metallic electrical contact element of claim 1, in which said periphery of the roller is absorbent.
Claim 5
Dependent Claim
34 words
The metallic electrical contact element of claim 1, which has been cantileverly and yieldably engaged with the peripheral surface of the roller to control the amount of electrolyte and metal deposited on the contact.
