Abstract

A clamp for electrically connecting a part to be anodized to a conductive bar having a member adapted to attach to the bar and a frame disposed on said member for holding the part to be anodized. Electrical contacts within the frame are forced against the conductive bar and the part to be anodized in the clamped position.

Claims

1. 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.

2. The apparatus of claim 1 wherein said frame is an integral portion of said member.

3. 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.

4. The apparatus of claim 3 wherein said rivets are made from columbium titanium.

5. 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.

6. The apparatus of claim 5 wherein said spring is constructed from commercially pure titanium.

7. 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.

8. The apparatus of claim 7 wherein said frame, said member and said lever are constructed from high density polypropylene plastic.
