  • Patent number: 9751148
    Abstract: A plumber's heat shield comprises an arcuate preferably metallic shell attached to a spring-clamp by means of an obedient shaft which enables the heat shield to be moved to any position relative to the spring-clamp. The arcuate shell is preferably formed from aluminum or other material having high infrared reflectivity. The obedient shaft is preferably formed from helically-wound steel spring outer sheath surrounding a ductile copper wire core. The spring steel outer sheath prevents the ductile copper wire core from being bent at too sharp of a radius (which would cause the ductile core to work-harden and fracture) while at the same time protecting the ductile copper wire core from the open-flame of the soldering torch.

  • Patent number: 8690040
    Abstract: A method of forming a solder joint includes the steps of providing a heat shield member formed as an arcuate preferably metallic shell attached to a spring-clamp by means of an obedient shaft; attaching the spring clamp to a structure adjacent the solder joint; moving the heat shield member by bending the obedient shaft so that the heat shield member is positioned in a location spaced-apart from the solder joint with the concave surface of the heat shield member facing the solder joint; and applying heat from a torch to the solder joint from the side opposite the heat shield so that the heat shield reflects the heat back onto the solder joint.
