Dependent claims

A repair member for repairing a heating coil element wire having a break defined therein forming a first end and a second end of said heating coil element wire, said first end disposed on one side of said break and said second end disposed on the other side of said break, said heating coil element wire made of a selected metal, said heating coil element wire having a diameter, comprising:

a cylindrical member having a diameter and first and second member ends, said cylindrical member made of the same selected metal as said heating coil element wire, said cylindrical member having a solid central body portion, a first end portion and a second end portion, said first end portion and said second end portion disposed, respectively, at said first and second member ends of said cylindrical member, said first and second member ends of said cylindrical member having, respectively, a first aperture and a second aperture defined axially therein forming walls around said first and second apertures, said walls having a thickness, said first and second apertures each having approximately the same diameter as the diameter of said heating coil element wire for receipt therein, respectively, of one of said first and second ends of said heating coil element wire, said first and second end portions with said first and second ends of said heating coil element wire disposed therein to be crimped to retain said first and second ends of said heating coil element wire, respectively, in said first and second end portions of said cylindrical member to provide electrical continuity through said heating coil element wire;
and
wherein said cylindrical member is approximately 0.75 inch in length and has a diameter of 0.100 inch, said first and second end portions of said cylindrical member are each approximately 0.25 inch in length, said central body portion is approximately 0.25 inch in length, said diameter of each of said first and second apertures is approximately 0.064 inch, and said walls around said first and second apertures each have a thickness of 0.018 inch.
