Abstract
Abstract Apparatus for electroplating a plurality of articles such as bolts, nuts, rivets, machine screws, and the like, in a molten salt bath wherein the articles are located in a spaced relationship on a cathode member in the bath. The articles are in line or face electrical contact with the cathode member and are caused to rotate on the cathode member. Preferably, relative movement is imparted between the cathode member and a holding means for the articles to cause the rotation of the articles relative to the cathode member.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
223 words
A molten salt electroplating apparatus comprising: a vessel adapted to contain molten salt electroplating bath; cathode belt means adapted to receive articles to be plated thereon; a fastener belt means adjacent said cathode belt means and having a plurality of spaced projections thereon, said projections extending above said cathode belt and being adapted to receive the articles to be plated therebetween and to maintain the articles on the cathode belt means in a predetermined spaced apart relationship with said articles in electrical contact with said cathode belt means; means for moving said cathode belt means through said electroplating bath at a first rate of speed; means for moving said fastener belt means through said electroplating bath in the same direction as that of said cathode belt means and a second rate of speed different from said first rate of speed of movement of said cathode belt means so that the articles to be coated are rotated relative to said cathode belt means and relative to said fastener belt means by said movement of said cathode belt means and said fastener belt means through said electroplating bath at said different rates of speed, to thereby uniformly plate said articles as they are fed through said electroplating bath; and means for applying direct current to both the cathode belt means and said fastener belt means.
Claim 2
Dependent Claim
223 words
A molten salt electroplating apparatus comprising: a vessel adapted to contain molten salt electroplating bath; cathode belt means adapted to receive articles to be plated thereon; a fastener belt means adjacent said cathode belt means and having a plurality of spaced projections thereon, said projections extending above said cathode belt and being adapted to receive the articles to be plated therebetween and to maintain the articles on the cathode belt means in a predetermined spaced apart relationship with said articles in electrical contact with said cathode belt means; means for moving said cathode belt means through said electroplating bath at a first rate of speed; means for moving said fastener belt means through said electroplating bath in the same direction as that of said cathode belt means and a second rate of speed different from said first rate of speed of movement of said cathode belt means so that the articles to be coated are rotated relative to said cathode belt means and relative to said fastener belt means by said movement of said cathode belt means and said fastener belt means through said electroplating bath at said different rates of speed, to thereby uniformly plate said articles as they are fed through said electroplating bath; and means for applying direct current to both the cathode belt means and said fastener belt means.
Claim 3
Dependent Claim
25 words
Apparatus according to claim 1 wherein said fastener belt is engaged with said cathode belt, said belts being relatively movable with respect to each other.
Claim 4
Dependent Claim
20 words
Apparatus according to claim 1 wherein said cathode belt means is below said fastener belt means in said electroplating bath.
Claim 5
Dependent Claim
23 words
Apparatus according to claim 3 wherein said projections of said fastener belt means extend above the upper surface of said cathode belt means.
Claim 6
Dependent Claim
24 words
Apparatus according to claim 3 wherein said fastener belt means has a longitudinal recess therein, and said cathode belt is received in said recess.
Claim 7
Dependent Claim
29 words
Apparatus according to claim 1 comprising an anode member in said electroplating bath, said anode member being movable in an up and down direction relative to said electroplating bath.
Claim 8
Dependent Claim
13 words
Apparatus according to claim 5 wherein said anode member is an anode rod.
Claim 9
Dependent Claim
49 words
Apparatus according to claim 1 wherein said projections of said fastener belt means includes first projections maintaining said articles in said spaced apart relationship on said cathode belt means and second projections to retain the article in position in the transverse direction of said fastener and cathode belt means.
Claim 10
Dependent Claim
23 words
Apparatus according to claim 8 wherein said second projections are located between first projections in the longitudinal direction of said fastener belt means.
Claim 11
Dependent Claim
33 words
Apparatus according to claim 1 comprising shoe means below said fastener belt means and said cathode belt means for supporting said fastener and cathode belt means during movement thereof through said electroplating bath.
Claim 12
Dependent Claim
37 words
ApparatUs according to claim 10 wherein said cathode belt means is below said fastener means and comprising means for slidably engaging said cathode belt means with said shoe means for guiding and supporting said cathode belt means.
