Jumper cable assembly

Claim 1

A jumper cable assembly comprising a pair of battery contact clamps, each battery contact clamp comprising a lower member having a pair of lower parallel ears with aligned lower apertures and having one end terminating into a lower jaw portion having a structure defining a plurality of teeth; an upper member having a pair of upper parallel ears with aligned upper apertures that register with the lower apertures of said lower parallel ears of said lower member when said upper parallel ears and said lower parallel ears mate, said upper member additionally having an end terminating into an upper jaw portion having a structure defining a plurality of teeth; a rivet means passing through said lower and upper apertures pivotally securing said lower member to said upper member such that the jaw portions of the lower and upper member cooperate with each other respectively; torsion spring means for urging said jaw portions together in a touching relationship about said rivet means and maintaining said jaw portions in a touching relationship when said clamp is in a closed posture, said torsion spring means having convolutions that are positioned around the rivet means and an upper end and a lower end that respectively engage the upper and lower members, said upper end and said lower end of said torsion spring means extend away from said rivet means in the same direction and in an opposed relationship with respect to each other; a lug terminal means pivotally secured to said lower member, said lug terminal means being contacted biasingly by said lower end of said torsion spring means to retain and urge said lug terminal means against said lower member and assist in retaining any cable engaged to the lug terminal means against the lower member; a pair of cables with one cable secured to the lug terminal means of one of the battery contact clamps and the other cable secured to the lug terminal means of the other battery contact clamp; and a connector secured to the ends of the pair of cables opposed to the ends secured to the lug terminal means of the pair of battery contact clamps.

Claim 9

A method for jumping and energizing a side-mount battery having a side-mount battery terminal comprising the steps of: (a) providing a battery and a first connector means and a pair of first connector cables interconnecting said first connector means with said battery; (b) providing a second connector means and a pair of battery contact clamps and a pair of second connector cables interconnecting said second connector means with said pair of battery contact clamps; (c) mating releasably the first connector means with the second connector means; (d) grasping a pair of handles of said battery contact clamp which are riveted pivotally together and such has a U-shaped configuration and includes a jaw having a plurality of teeth formed and structured along a pair of sides and the front of the respective jaw, said teeth of said jaws of said handles being in a touching, occlusive relationship when said clamp is in a closed posture and urged biasingly together by a torsion spring means that convolutes the rivet and includes a pair of spring arms that extend from the convolutions of the spring in the same direction in an opposed relationship with respect to each other and into the U-shaped handles with one of the spring arms having a lip and contacting biasingly between the convolutions and the lip a lug terminal pivotally secured within one of the U-shaped handles to urge and hold the lug terminal within and against the inside of the U-shaped handle and protect the user from accidentally contacting a cable secured to the lug terminal and passing underneath said lip of said spring arm; (e) forcing the jaws of the handles apart by pressuring the handles against the spring arms of the torsion spring; (f) positioning the open jaws of step (e) around a counter-sunk battery bolt within a side-mount battery terminal of a side-mount battery; and (g) releasing the pressure off the handles such that the jaws of the handles close around the counter-sunk battery bolt.

Claim 10

A method for jumping and energizing a side-mount battery having a side-mount battery terminal comprising the steps of: (a) providing a battery and a first connector means and a pair of first connector cables interconnecting said first connector means with said battery; (b) providing a second connector means and a pair of battery contact clamps and a pair of second connector cables interconnecting said second connector means with said pair of battery contact clamps; (c) mating releasably the first connector means with the second connector means; (d) grasping a pair of handles of said battery contact clamp which are riveted pivotally together and such has a U-shaped configuration and includes a jaw having a plurality of teeth formed and structured along a pair of sides and the front of the respective jaw, said teeth of said jaws of said handles being in a touching, occlusive relationship when said clamp is in a closed posture and urged biasingly together by a torsion spring means that convolutes the rivet and includes a pair of spring arms that extend from the convolutions of the spring in the same direction in an opposed relationship with respect to each other and into the U-shaped handles with one of the spring arms having a lip and contacting biasingly between the convolutions and the lip a lug terminal pivotally secured within one of the U-shaped handles to urge and hold the lug terminal within and against the inside of the U-shaped handle and protect the user from accidentally contacting a cable secured to the lug terminal and passing underneath said lip of said spring arm; (e) forcing the jaws of the handles apart by pressuring the handles against the spring arms of the torsion spring; (f) positioning the open jaws of step (e) around a counter-sunk battery bolt within a side-mount battery terminal of a side-mount battery; and (g) releasing the pressure off the handles such that the jaws of the handles close around the counter-sunk battery bolt.
