Abstract
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. The support and elements are made of an electrically conductive material but are completely covered, except for the object-engaging surfaces, by an electrically non-conductive material.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
97 words
A clamping device for gripping an object, comprising: a. a support; b. two elements on said support each having an object-engaging portion comprising a section having an elongated edge surface, said respective edge surfaces facing and at least partially registering with each other in substantially parallel horizontal planes and being in relatively skewed vertical planes; c. resilient means operatively connected to said elements for biasing said object-engaging portions toward and into engagement with each other; and d. means operatively connected to at least one of said elements for deforming said resilient means to separate said object-engaging portions.
Claim 2
Dependent Claim
97 words
A clamping device for gripping an object, comprising: a. a support; b. two elements on said support each having an object-engaging portion comprising a section having an elongated edge surface, said respective edge surfaces facing and at least partially registering with each other in substantially parallel horizontal planes and being in relatively skewed vertical planes; c. resilient means operatively connected to said elements for biasing said object-engaging portions toward and into engagement with each other; and d. means operatively connected to at least one of said elements for deforming said resilient means to separate said object-engaging portions.
Claim 3
Dependent Claim
15 words
The device of claim 1, wherein said vertical planes are substantially perpendicular to each other.
Claim 4
Dependent Claim
31 words
The device of claim 1, wherein said elements and said support are electrically conductive, and further comprising an electrically insulating material covering the entire clamping device except for said edge surfaces.
Claim 5
Dependent Claim
12 words
The device of claim 1 wherein said edge surfaces are substantially planar.
Claim 6
Dependent Claim
164 words
A clamping device for gripping a plurality of objects, comprising; a. a support having a plurality of spaced object-engaging portions attached thereto equal to the number of objects to be gripped, each of said support object-engaging portions including an elongated edge surface; b. a like plurality of elements on said support spaced from one another, each of said elements having an object-engaging portion facing one of said support object-engaging portions and including an elongated edge surface, corresponding support and element edge surfaces facing and at least partially registering with each other in substantially parallel horizontal planes and being in relatively skewed planes; c. resilient means operatively connected to said support and each of said elements, respectively, for biasing each of said element object-engaging portions toward and into engagement with its corresponding support object-engaging portion; and d. individual means operatively connected, respectively, to each of said elements for deforming said resilient means to individually separate each element object-engaging portion from its corresponding support object-engaging portion.
Claim 7
Dependent Claim
164 words
A clamping device for gripping a plurality of objects, comprising; a. a support having a plurality of spaced object-engaging portions attached thereto equal to the number of objects to be gripped, each of said support object-engaging portions including an elongated edge surface; b. a like plurality of elements on said support spaced from one another, each of said elements having an object-engaging portion facing one of said support object-engaging portions and including an elongated edge surface, corresponding support and element edge surfaces facing and at least partially registering with each other in substantially parallel horizontal planes and being in relatively skewed planes; c. resilient means operatively connected to said support and each of said elements, respectively, for biasing each of said element object-engaging portions toward and into engagement with its corresponding support object-engaging portion; and d. individual means operatively connected, respectively, to each of said elements for deforming said resilient means to individually separate each element object-engaging portion from its corresponding support object-engaging portion.
Claim 8
Dependent Claim
45 words
The device of claim 5, wherein said deforming means is comprised of an extension of each of said elements, the extension of one element extending over the other element proper, each element extension including a recess accommodating the recessed portion of the other element extension.
Claim 9
Dependent Claim
12 words
The device of claim 6, wherein the said elements are substantially identical.
Claim 10
Dependent Claim
56 words
The device of claim 5, wherein said resilient means is comprised of a resilient strip bent at both ends and operably connected at its central portion to said support, each of said bent ends being operably connected to a different one of said elements and in its biased state being substantially parallel to said central portion.
Claim 11
Dependent Claim
16 words
The device of claim 8, wherein the corresponding vertical planes are substantially perpendicular to each other.
Claim 12
Dependent Claim
35 words
The device of claim 5, wherein said elements, said support object-engaging portions, and said support are electrically conductive, and further comprising an electrically insulating material covering the entire clamping device except for said edge surfaces.
Claim 13
Dependent Claim
16 words
The device of claim 5, wherein the corresponding vertical planes are substantially perpendicular to each other.
Claim 14
Dependent Claim
12 words
The device of claim 5 wherein said edge surfaces are substantially planar.
