Abstract

A battery booster cable clamp includes first and second members each containing an arm and a jaw joined in the nature of pliers with one arm containing an upwardly extending flexible member containing a plurality of teeth engaging a projection on the end of the other arm to achieve a ratchet action, electrically conductive teeth being disposed at each of the jaws whereby bringing the arms together will bring the jaws together to permit clamping the teeth on a battery post or terminal.

Claims

1. A clamp for a battery booster cable comprising:

(a) a first member having at one end thereof a substantially horizontally extending first arm portion of a first width, an essentially horizontally extending first jaw portion at the other end thereof and a substantially vertical portion of a width approximately half said first width joining said first arm portion and said first jaw portion;

(b) a second member of essentially identical design having a second arm portion and second jaw portion and a second essentially vertical portion, said first and second members placed with their substantially vertical portions in abutting relationship with said first arm portion disposed directly above said second arm portion and said second jaw portion disposed directly above the first jaw portion;

(c) hinging means at said first and second substantially vertical portions joining said first and second members thereby forming a structure in the nature of a pliers whereby relative movement of said arm portions together and away from each other will result in similar movement of said jaw portions;

(d) an arcuate, flexible member extending essentially in a vertical direction from one of said arm portions, said flexible member contain thereon a plurality of teeth pointing in a direction toward said arm portion said flexible member biased in a direction toward said jaw portions;

(e) a projection on the end of said other arm portion adapted to engage said teeth;

(f) a first tooth conductive member disposed at the inside of said first jaw portion, its teeth pointing toward said second jaw portion;

(g) a second conductive member disposed at the inside of said second jaw portion, its teeth pointing toward said first jaw portion, whereby said jaw portions may be separated by applying a force against said flexible member to move it away from said teeth, said jaw portions placed around the battery terminal, said arm portions brought together thereby bringing said jaw portions together to apply a clamping force to said terminal and said jaw portions and arm portions held in position by the ratchet action existing between said teeth on said flexible member and said projection on said other arm portion.

2. Apparatus according to claim 1 wherein said means of attaching said first and second members comprises a rivet passing through said first and second vetical portions.

3. Apparatus according to claim 1 wherein said first and second members are made of a non-conductive plastic material and wherein said first and second toothed conductive members are attached to the ends of the jaw portions of said first and second members.

4. Apparatus according to claim 3 wherein said first and second jaw portions contain recesses therein and wherein said first and second toothed conductive members are disposed within said recesses having their teeth extending out therefrom.

5. Apparatus according to claim 4 wherein said toothed portions each comprise an essentially horizontal base portion and first, second and third vertically projecting portions each containing a plurality of small teeth on the end thereof, said base portions being inserted into said recess in said jaw portions with said vertical portions extending outward therefrom, one of said vertical portions being disposed at the outer end of said jaw portion and, a rivet passing through each of said jaw portions and each of said bases holding said bases against said jaw portions.

6. Apparatus according to claim 5 wherein said flexible member is molded integrally with said one of said first and second members.

7. Apparatus according to claim 6 and further including a recess in at least said one arm portion, a hole through the end of said one arm portion leading to said recess, an opening formed through said vertical portions into the recess of one of said jaw portions and a cable extending through said one arm portion and resting in the recess in said one arm portion and passing through said openings in said vertical portions and extending to said conductive member in said first jaw portion, said conductive member being conductively attached to said cable.
