the pivoting hardware set mechanically connects the first moveable portion to the second moveable portion so that the first and second moveable portions can rotate with respect to each other so that the first and second jaw portions move between the first open position and the first closed position;
the first movable portion comprises a first pivoting member which is elongated and has a first end, a second end and an intermediate portion located between the first end and the second end;
the second movable portion comprises a first pivoting member which is elongated and has a first end, a second end and an intermediate portion located between the first end and the second end;
the pivoting hardware set mechanically connects the intermediate portion of the first pivoting member to the intermediate portion of the second pivoting member to form a clamp having a scissors-type geometry;
the first pivoting member comprises the first handle member and the first portion of the first jaw-bearing member, with the first handle member and the first portion of the jaw-bearing member being rigidly mechanically connected to each other to make the first pivoting member generally Z-shaped;
the second pivoting member comprises the second handle member and the first portion of the second jaw-bearing member, with the second handle member and the second portion of the jaw-bearing member being rigidly mechanically connected to each other to make the first pivoting member generally Z-shaped;
the first jaw portion comprises the second portion of the first jaw-bearing member; and
the second jaw portion comprises the second portion of the second jaw-bearing member; and
the jumper cable contact comprises an electrical contact path and a contact member;
the electrical contact path forms an electrical conduction path that electrically connects the first jaw member to the contact member; and
the contact member is sized and shaped to be electrically and mechanically connected to an end of a jumper cable.

Abstract
One aspect of the present invention is a jumper cable clamp that is biased to a position with its jaws open. Another aspect of the present invention is a jumper cable clamp that uses biases open its jaws using torsional tension in a helical spring. Another aspect of the present invention is a jumper cable clamp that includes a set of jaws, a jaw-biasing hardware set and a ratchet hardware set where: (i) the jaw-biasing hardware set biases the jaws towards an open position; and (ii) the ratchet hardware set holds the position of the jaws at regular positional increments as the jaws are moved, against the bias provided by the jaw-biasing hardware set, towards a closed position. Preferably, the ratchet hardware set further includes a quick release mechanism structured, located, sized, shaped and/or mechanically connected to release a ratcheted engagement of the ratchet hardware set upon activation of the quick release mechanism.
