Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
124 words
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.
Claim 2
Dependent Claim
124 words
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.
Claim 3
Dependent Claim
39 words
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.
Claim 4
Dependent Claim
52 words
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.
Claim 5
Dependent Claim
38 words
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.
Claim 6
Dependent Claim
35 words
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.
Claim 7
Dependent Claim
