Abstract
Abstract An intercell connector system is disclosed. The system includes two adjacent terminals attached to two adjacent cells and intercell connector selectively overlapping the adjacent ends of the terminals. The intercell connector includes a conductive first member and a second member which are held together by a fastening device which can be selectively loosened and tightened. When the fastening device is loosened, the two members are adapted to be moved out of engagement with one of the terminals thereby disconnecting the electrical circuit between the terminals.

Claim 1
Independent Claim
230 words
A cell connector system for electrically connecting and disconnecting a first electrolytic cell adjacent to a second electrolytic cell in series, wherein said system is comprised of: (a) a cathode terminal attached electrically to said first cell and projecting towards said second cell, (b) an anode terminal attached electrically to said second cell and projecting towards said cathode terminal, (c) each of said terminals having a top side and a bottom side and an outer portion, (d) at least one of said terminals having multiple lateral recesses in said outer portion, (e) a conductive first member overlapping one of said outer sides and said portion of each of said terminals, (f) a second member overlapping the other of said sides and said outer portion of each of said terminals, (g) a plurality of fastener means aligned laterally with said recesses for connecting said first member and said second member, and (1) for pressing said first member and said second member into tight electrical contact with said terminals, whereby current flows between said terminals through said conductive first member, and (2) means for sliding said fastening means into said recesses towards one of said electrolytic cells and for moving said members towards one of said electrolytic cells when said members are not pressed into tight electrical contact with said terminals, thereby disengaging said first conductive member from one of said terminals.
Claim 2
Dependent Claim
230 words
A cell connector system for electrically connecting and disconnecting a first electrolytic cell adjacent to a second electrolytic cell in series, wherein said system is comprised of: (a) a cathode terminal attached electrically to said first cell and projecting towards said second cell, (b) an anode terminal attached electrically to said second cell and projecting towards said cathode terminal, (c) each of said terminals having a top side and a bottom side and an outer portion, (d) at least one of said terminals having multiple lateral recesses in said outer portion, (e) a conductive first member overlapping one of said outer sides and said portion of each of said terminals, (f) a second member overlapping the other of said sides and said outer portion of each of said terminals, (g) a plurality of fastener means aligned laterally with said recesses for connecting said first member and said second member, and (1) for pressing said first member and said second member into tight electrical contact with said terminals, whereby current flows between said terminals through said conductive first member, and (2) means for sliding said fastening means into said recesses towards one of said electrolytic cells and for moving said members towards one of said electrolytic cells when said members are not pressed into tight electrical contact with said terminals, thereby disengaging said first conductive member from one of said terminals.
