Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
251 words
A connector for a plate electrode comprising in combination a resilient body comprising an upper member and a lower member spaced from each other at one end thereof and rigidly attached to each other at the opposite end thereof; flexible, resilient first electrically conductive sheet means adjacent said upper member, means holding said first electrically conductive sheet means between said upper and lower members and adjacent said upper member, at least a portion of the surface of said first electrically conductive sheet means nonadjacent to said upper member containing means for resisting movement of said plate electrode from between said first electrically conductive sheet means and said lower member, a pivoting lever means attached to said upper member and having one end thereof adjacent said first electrically conductive sheet means, said lever means adapted to move from a first open position whereby said first electrically conductive sheet means is adjacent said upper member to a second closed position where said first electrically conductive sheet means is deflected to be adjacent said lower member with said plate electrode held between said first electrically conductive sheet means and said lower member and said plate electrode contacting the surface of said first electrically conductive sheet means containing means for resisting movement of said plate electrode from between said first electrically conductive sheet means and said lower member, and second electrically conductive means attached to said first electrically conductive sheet means for electrically connecting said first electrically conductive sheet means to an electrical power source.
Claim 2
Dependent Claim
251 words
A connector for a plate electrode comprising in combination a resilient body comprising an upper member and a lower member spaced from each other at one end thereof and rigidly attached to each other at the opposite end thereof; flexible, resilient first electrically conductive sheet means adjacent said upper member, means holding said first electrically conductive sheet means between said upper and lower members and adjacent said upper member, at least a portion of the surface of said first electrically conductive sheet means nonadjacent to said upper member containing means for resisting movement of said plate electrode from between said first electrically conductive sheet means and said lower member, a pivoting lever means attached to said upper member and having one end thereof adjacent said first electrically conductive sheet means, said lever means adapted to move from a first open position whereby said first electrically conductive sheet means is adjacent said upper member to a second closed position where said first electrically conductive sheet means is deflected to be adjacent said lower member with said plate electrode held between said first electrically conductive sheet means and said lower member and said plate electrode contacting the surface of said first electrically conductive sheet means containing means for resisting movement of said plate electrode from between said first electrically conductive sheet means and said lower member, and second electrically conductive means attached to said first electrically conductive sheet means for electrically connecting said first electrically conductive sheet means to an electrical power source.
Claim 3
Dependent Claim
64 words
The connector of claim 1 wherein said first electrically conductive sheet means comprises a multiplicity of C-shaped metallic sheets laterally separated from each other, having the upper portion of each of said sheets adjacent said upper member and the lower portion of each of said sheets adjacent said lower member; each of said metallic sheets being attached to a separate second electrically conductive means.
Claim 4
Dependent Claim
13 words
The connector of claim 2 wherein said lever means comprises an L-shaped lever.
Claim 5
Dependent Claim
30 words
The connector of claim 3 wherein said means for resisting movement comprises raised metallic portions in the facing surfaces of the upper and lower portions of said C-shaped metallic sheets.
Claim 6
Dependent Claim
34 words
A connector of claim 3 wherein said means for resisting movement comprises raised metallic portions on at least one of the facing surfaces of the upper and lower portions of said C-shaped metallic sheet.
Claim 7
Dependent Claim
33 words
The connector of claim 1 wherein said first electrically conductive sheet means comprises a C-shaped metallic sheet having its upper portion adjacent said upper member and its lower portion adjacent said lower member.
Claim 8
Dependent Claim
13 words
The connector of claim 6 wherein said lever means comprises an L-shaped lever.
Claim 9
Dependent Claim
30 words
The connector of claim 7 wherein said means for resisting movement comprises raised metallic portions on the facing surfaces of the upper and lower portions of said C-shaped metallic sheet.
Claim 10
Dependent Claim
34 words
A connector of claim 7 wherein said means for resisting movement comprises raised metallic portions on at least one of the facing surfaces of the upper and lower portions of said C-shaped metallic sheet.
Claim 11
Dependent Claim
259 words
A connector for a plate electrode comprising in combination a resilient body comprising an upper member and a lower member spaced from each other at one end thereof and rigidly attached to each other at the opposite end thereof; flexible, resilient first electrically conductive sheet means adjacent said upper member; second electrically conductive sheet means adjacent said lower member, means holding said first electrically conductive sheet means and said second electrically conductive sheet means between said upper and lower members, at least a portion of at least one facing surface of said first and second electrically conductive sheet means containing means for resisting movement of said plate electrode from between said first and second electrically conductive sheet means, a pivoting lever means attached to said upper member and having one end thereof adjacent said first electrically conductive sheet means, said lever means adapted to move from a first open position where said first electrically conductive sheet means is adjacent said upper member to a second closed position where said first electrically conductive sheet means is deflected to be adjacent said lower member with said plate electrode held between said first and second electrically conductive sheet means and said plate electrode contacting said means for resisting movement of said plate electrode from between said first and second electrically conductive sheet means, and third electrically conductive means attached to at least one of said first and second electrically conductive sheet means for electrically connecting at least one of said first and second electrically conductive sheet means to an electrical power source.
Claim 12
Dependent Claim
259 words
A connector for a plate electrode comprising in combination a resilient body comprising an upper member and a lower member spaced from each other at one end thereof and rigidly attached to each other at the opposite end thereof; flexible, resilient first electrically conductive sheet means adjacent said upper member; second electrically conductive sheet means adjacent said lower member, means holding said first electrically conductive sheet means and said second electrically conductive sheet means between said upper and lower members, at least a portion of at least one facing surface of said first and second electrically conductive sheet means containing means for resisting movement of said plate electrode from between said first and second electrically conductive sheet means, a pivoting lever means attached to said upper member and having one end thereof adjacent said first electrically conductive sheet means, said lever means adapted to move from a first open position where said first electrically conductive sheet means is adjacent said upper member to a second closed position where said first electrically conductive sheet means is deflected to be adjacent said lower member with said plate electrode held between said first and second electrically conductive sheet means and said plate electrode contacting said means for resisting movement of said plate electrode from between said first and second electrically conductive sheet means, and third electrically conductive means attached to at least one of said first and second electrically conductive sheet means for electrically connecting at least one of said first and second electrically conductive sheet means to an electrical power source.
