  • Patent number: 3970540
    Abstract: A clamping device for use in an electroplating process is provided having a support with at least one object-engaging portion. At least one element is resiliently attached to the support with each element having an object-engaging portion facing a corresponding object-engaging portion on the support. The element object-engaging portion is resiliently biased toward its corresponding support object-engaging portion. A manually engageable means is attached to each element for separating the element object-engaging portion from its corresponding support object-engaging portion. When more than one element is used, each is individually movable by the manually engageable means. The corresponding object-engaging portions have object-engaging surfaces which are, respectively, in parallel planes. The corresponding object-engaging portions are skewed relative to one another.
