Abstract 1. An apparatus for simultaneously electroplating the inside surfaces of a plurality of annular bodies arranged one above the other and with the inside surfaces in registry with each other, comprising: a plurality of seats one each interposed between any adjacent pair of said annular bodies for electrically insulating the same from each other and for keeping hermetically sealed adjacent annular bodies; an upright anode having an outer surface for forming between the outer surface and the inside surfaces of said tubular bodies a first electrolyte passage in which an electrolyte is forced to flow; a cathode conductor having individual means for electrical connection with each of said annular bodies for applying to the same a negative potential; a hat hermetically mounted on the uppermost of said seats for defining with the bodies and anode a sealed chamber; a second electrolyte passage longitudinally formed in said anode for passing therethrough an electrolyte and having a fluid communication with the first-named electrolyte passage by way of said chamber; and a detergent-air passage longitudinally formed in said anode for selectively passing therethrough a detergent and fresh air and having an outlet port extending into said chamber for cleaning said chamber and said first and second electrolyte passages, both for diluting therewith gases remaining in said chamber and for scavenging the first and second electrolyte passages, after the electroplating operation has been completed.
