  • Patent number: 4269686
    Abstract: Apparatus for electroplating bearing surfaces of a crankshaft while the crankshaft is submerged in a plating tank containing a plating bath. A current conducting mount means is affixed to and rotatably supports a plurality of crankshafts submerged in the plating bath. The mount means includes a cylindrical housing having a spindle which extends therethrough so that one end of opposed crankshafts can be attached to opposed ends of the spindle, thereby enabling several crankshafts to be simultaneously electroplated. Seal means forms a mercury chamber between the housing and the spindle, and another seal means located at opposed ends of the housing forms a bearing chamber which protects a bearing means from the plating bath. Hence, the bearings are protected from the mercury by one of the seal means and from the plating bath by the other seal means.
