Abstract
Abstract A plating apparatus for plating a member which includes a casing having a chamber formed therein for housing the member to be plated, an inlet port for receiving plating fluid, and an outlet port for discharging the plating fluid, the inlet and outlet ports being in communication with each other through the chamber wherein the casing further includes a first member having the inlet and outlet ports formed therein, and a second member connected to the first member, an electrode operatively associated with the member to be plated, an actuating mechanism for disconnecting the second member from the first member and a mechanism for supplying the plating fluid to the inlet port.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
217 words
Apparatus for electroplating an article, said apparatus comprising: (a) a first member having therein an inlet port into which plating fluid is supplied during plating operations, a first passageway in fluid communication with said inlet port and with a working face of said first member, an outlet port, and a third passageway in fluid communication with said outlet port and with said working face of said first member; (b) a second member having therein a second passageway in fluid communication at both ends with a working face of said second member; (c) the working faces of said first and second members defining a chamber therebetween which is in fluid communication with one end of said second passageway and with either said first passageway or said second passageway during plating operations, the other of said first or second passageways being simultaneously in fluid communication with the other end of said second passageway; (d) said chamber being adapted to entirely contain the article to be plated during a plating operation such that the plating fluid flows through said chamber in one direction without doubling back on itself; (e) first electrode means adapted to be operatively associated with the article to be plated; and (f) second electrode means positioned to cooperate with said first electrode means to electroplate the article.
Claim 2
Dependent Claim
217 words
Apparatus for electroplating an article, said apparatus comprising: (a) a first member having therein an inlet port into which plating fluid is supplied during plating operations, a first passageway in fluid communication with said inlet port and with a working face of said first member, an outlet port, and a third passageway in fluid communication with said outlet port and with said working face of said first member; (b) a second member having therein a second passageway in fluid communication at both ends with a working face of said second member; (c) the working faces of said first and second members defining a chamber therebetween which is in fluid communication with one end of said second passageway and with either said first passageway or said second passageway during plating operations, the other of said first or second passageways being simultaneously in fluid communication with the other end of said second passageway; (d) said chamber being adapted to entirely contain the article to be plated during a plating operation such that the plating fluid flows through said chamber in one direction without doubling back on itself; (e) first electrode means adapted to be operatively associated with the article to be plated; and (f) second electrode means positioned to cooperate with said first electrode means to electroplate the article.
Claim 3
Dependent Claim
35 words
Apparatus as recited in claim 1 and further comprising means for moving said second member away from said first member so that articles to be plated can be inserted into and removed from said chamber.
Claim 4
Dependent Claim
16 words
Apparatus as recited in claim 1 wherein said second electrode is displaceably mounted within said chamber.
Claim 5
Dependent Claim
34 words
Apparatus as recited in claim 1 wherein said chamber is sized such that there is a gap between the inner walls of said chamber and the outer walls of the article to be plated.
Claim 6
Independent Claim
229 words
A method of electroplating an article, said method comprising the steps of: (a) providing a first member having therein an inlet port into which plating fluid is supplied during plating operations, a first passageway in fluid communication with said inlet port and with a working face of said first member, an outlet port, and a third passageway in fluid communication with said outlet port and with said working face of said first member; (b) providing a second member having therein a second passageway in fluid communication at both ends with a working face of said second member; (c) the working faces of said first and second members defining a chamber therebetween which is in fluid communication with one end of said second passageway and with either said first passageway or said second passageway during plating operations, the other of said first or second passageways being simultaneously in fluid communication with the other end of said second passageway; (d) placing the article to be plated in said chamber; (e) connecting a first electrode means to the article to be plated; (f) providing a second electrode means in position to cooperate with said first electrode means to electroplate the article; (g) causing the plating fluid to flow through said chamber in one direction without doubling back on itself; and (h) providing an electroplating voltage differential between said first and second electrodes.
Claim 7
Independent Claim
229 words
A method of electroplating an article, said method comprising the steps of: (a) providing a first member having therein an inlet port into which plating fluid is supplied during plating operations, a first passageway in fluid communication with said inlet port and with a working face of said first member, an outlet port, and a third passageway in fluid communication with said outlet port and with said working face of said first member; (b) providing a second member having therein a second passageway in fluid communication at both ends with a working face of said second member; (c) the working faces of said first and second members defining a chamber therebetween which is in fluid communication with one end of said second passageway and with either said first passageway or said second passageway during plating operations, the other of said first or second passageways being simultaneously in fluid communication with the other end of said second passageway; (d) placing the article to be plated in said chamber; (e) connecting a first electrode means to the article to be plated; (f) providing a second electrode means in position to cooperate with said first electrode means to electroplate the article; (g) causing the plating fluid to flow through said chamber in one direction without doubling back on itself; and (h) providing an electroplating voltage differential between said first and second electrodes.
Claim 8
Dependent Claim
52 words
A method as recited in claim 5 and further comprising the steps of: (a) moving said second member away from said first member and (b) removing a plated article from said chamber and inserting an article to be plated into said chamber while said second member is spaced from said first member.
Claim 9
Dependent Claim
35 words
A method as recited in claim 5 wherein said chamber is sized such that there is a gap between the inner wall of the chamber and the outer wall of the article to be plated.
