Abstract

A standard form of cast alluminum ground clamp is disclosed wherein the connecting means provided at the pivot point has shock absorbing properties and is comprised of a resilient sleeve surrounding the interconnecting rivet.

Claims

1. An electrical clamp comprising:

a lower member having at one end thereof a jaw portion;

an upper member of channel configuration having at one end thereof a jaw portion for cooperating with the jaw portion of said lower member, and intermediate it'"'"''"'"'s ends on opposite side walls thereof integral parallel ears with aligned holes defining a pivot point, said parallel ears extending along the outside surfaces of said lower member;

tension means cooperating with said upper and lower member for urging said jaw portions together about said pivot point; and

means connecting said upper member to said lower member at said pivot point, said means surrounded by a resilient sleeve member which extends at least to the said outside surfaces of said lower member.

2. An electrical clamp in accordance with claim 1 wherein:

said sleeve member has an outside diameter greater than the diameter of said aligned holes, and a length equal to the distance between the outside surfaces of said lower member.

3. An electrical clamp in accordance with claim 2 wherein:

said lower member is of channel configuration and has intermediate its ends on opposite side walls thereof integral parallel ears with aligned holes at said pivot point; and

said sleeve member includes, an inner sleeve of resilient plastic, and an outer metallic sleeve.

4. An electrical clamp in accordance with claim 3 wherein:

said tension means is a torsion spring, the convolutions thereof being positioned around said sleeve member, and the ends thereof being in engagement with said upper and lower members.

5. An electrical clamp in accordance with claim 4 wherein:

said inner sleeve is comprised of cast, unfilled polyurethane having a durometer reading of approximately 88; and

said outer sleeve is comprised of ductile, half-hard brass.

6. An electrical clamp in accordance with claim 1 wherein:

each of said jaw portions includes, intermediate the tips and said pivot point;

integral projections providing a striking area and adapted to prevent contact between the tips of said jaw portions.
