Abstract

Abstract In a heat sealing operation for environmentally isolating joints and connections, a spring actuated clamp is utilized to provide positive engagement of the heat shrinkable material in the area between the members being connected. The clamp has two juxtaposed clamp arms with opposed convex clamping jaws. The clamp arms are resiliently loaded by a coil spring so the convex surfaces on the clamping jaws are placed into a clamping relationship on the heat shrinkable material.

Claims Analysis

Total Claims: 23
Claim 1
Independent Claim 210 words
Method for performing a heat sealing operation for environmentally isolating joints and connections comprising the steps of: providing a pair of juxtaposed elongated members having ends prepared for connection; providing another elongated member with its end prepared for connection to said ends of said pair of elongated members; connecting said another elongated member with said pair of elongated members at their ends; providing a heat shrinkable material and surrounding at least the connected ends of said another elongated member and said pair of elongated members with said heat shrinkable material; using a clamp to hold said heat shrinkable material together in an area between said pair of elongated members, said clamp including two pivotally connected juxtaposed clamp arms, each of said clamp arms having an elongated clamping jaw with a convex surface thereon, said clamping jaws extending outwardly from said clamp arms with said convex surfaces in an opposed relationship, and means operatively connected to said juxtaposed clamp arms and resiliently loading the same to place said convex surfaces into a clamping relationship with said heat shrinkable material therebetween; and heating said heat shrinkable material to shrink said material around the connected ends of said another elongated member and said pair of elongated members to environmentally isolate the connected ends.
Claim 2
Dependent Claim 210 words
Method for performing a heat sealing operation for environmentally isolating joints and connections comprising the steps of: providing a pair of juxtaposed elongated members having ends prepared for connection; providing another elongated member with its end prepared for connection to said ends of said pair of elongated members; connecting said another elongated member with said pair of elongated members at their ends; providing a heat shrinkable material and surrounding at least the connected ends of said another elongated member and said pair of elongated members with said heat shrinkable material; using a clamp to hold said heat shrinkable material together in an area between said pair of elongated members, said clamp including two pivotally connected juxtaposed clamp arms, each of said clamp arms having an elongated clamping jaw with a convex surface thereon, said clamping jaws extending outwardly from said clamp arms with said convex surfaces in an opposed relationship, and means operatively connected to said juxtaposed clamp arms and resiliently loading the same to place said convex surfaces into a clamping relationship with said heat shrinkable material therebetween; and heating said heat shrinkable material to shrink said material around the connected ends of said another elongated member and said pair of elongated members to environmentally isolate the connected ends.
