Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
95 words
An electrode extension connector for connecting two flux coated welding rods together in end to end relationship comprising a housing of generally cylindrical cross section and of electrical and heat insulative material, a block of electrically conductive material intermediate the ends of said housing adapted to abut the end of an electrode inserted in each end of said housing and a thermally and electrically insulative chuck means in each end of said housing for selectively detachably and removably engaging and gripping an uncoated welding electrode end in contact with said block of electrically conductive metal.
Claim 2
Dependent Claim
95 words
An electrode extension connector for connecting two flux coated welding rods together in end to end relationship comprising a housing of generally cylindrical cross section and of electrical and heat insulative material, a block of electrically conductive material intermediate the ends of said housing adapted to abut the end of an electrode inserted in each end of said housing and a thermally and electrically insulative chuck means in each end of said housing for selectively detachably and removably engaging and gripping an uncoated welding electrode end in contact with said block of electrically conductive metal.
Claim 3
Dependent Claim
49 words
An electrode extension connector as claimed in claim 1 wherein the chuck means includes a pair of jaws having tapered frusto-conical ends and a collet threaded thereon having a corresponding frusto-conical inner surface bearing on the jaws to close them together when the collet is tightened onto the jaws.
Claim 4
Dependent Claim
53 words
An electrode extension connector as claimed in claim 1 wherein the chuck means is an anvil fixed in each end of said housing, a hold down member movable above said anvil, guide means between said anvil and hold down member and means moving said hold down member toward and away from said anvil.
Claim 5
Dependent Claim
50 words
An electrode extension connector as claimed in claim 3 wherein the means for moving the hold down member toward and away from the anvil includes a screw member threaded in the housing end and bearing on the hold down member and resilient means between said hold down member and anvil.
Claim 6
Dependent Claim
21 words
An electrode extension connector as claimed in claim 1 or 2 or 3 or 4 wherein the metal block is copper.
Claim 7
Dependent Claim
22 words
An electrode extension connector as claimed in claim 1 or 2 or 3 or 4 wherein the housing is a straight cylinder.
Claim 8
Dependent Claim
27 words
An electrode extension connector as claimed in claim 1 or 2 or 3 or 4 wherein the housing forms an angle from one end to the other.
Claim 9
Dependent Claim
14 words
An electrode extension connector as claimed in claim 7 wherein the angle is 90°.
Claim 10
Dependent Claim
14 words
An electrode extension connector as claimed in claim 7 wherein the angle is 45°.
