Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
90 words
An apparatus for electrically connecting a part to be anodized to a conductor bar in an anodizing process which comprises: a member adapted to attach to said conductor bar; a frame disposed on said member for holding said part to be anodized; means for slidably mounting an electrical conductor within said frame between said conductor bar and said part to be anodized; and means for forcing said part to be anodized against the slidably mounted conductor for securing electrical contact between said conductor bar and said part to be anodized.
Claim 2
Independent Claim
90 words
An apparatus for electrically connecting a part to be anodized to a conductor bar in an anodizing process which comprises: a member adapted to attach to said conductor bar; a frame disposed on said member for holding said part to be anodized; means for slidably mounting an electrical conductor within said frame between said conductor bar and said part to be anodized; and means for forcing said part to be anodized against the slidably mounted conductor for securing electrical contact between said conductor bar and said part to be anodized.
Claim 3
Dependent Claim
15 words
The apparatus of claim 1 wherein said frame is an integral portion of said member.
Claim 4
Dependent Claim
51 words
The apparatus of claim 1 wherein said means for slidably mounting an electrical conductor within said frame comprises an aperture within said frame, and wherein said electrical conductor comprises a first rivet slidably disposed in said frame aperture and adapted to contact said conductor bar and said part to be anodized.
Claim 5
Dependent Claim
13 words
The apparatus of claim 3 wherein said rivets are made from columbium titanium.
Claim 6
Dependent Claim
61 words
The apparatus of claim 1 wherein said means for forcing said part to be anodized against said electrical conductor comprises: a spring having an open end and a closed end, said open end detachably secured to said member and said frame, said open end being smaller than the height of said member and said frame thereby urging said electrical conductors together.
Claim 7
Dependent Claim
14 words
The apparatus of claim 5 wherein said spring is constructed from commercially pure titanium.
Claim 8
Dependent Claim
50 words
The apparatus of claim 5 wherein a second rivet is secured to said frame generally opposite said first rivet and wherein a lever is pivotally disposed within said frame, said lever having a cam at one end, said cam adapted to separate the first and second rivets within said frame.
Claim 9
Dependent Claim
20 words
The apparatus of claim 7 wherein said frame, said member and said lever are constructed from high density polypropylene plastic.
