Patent number: 4809434Abstract: The specification discloses a hand held portable facing device to be used primarily for facing polystyrene building panels after installation. The facing device is constructed of a frame, a wire planing element, and tension arms which mount on the frame for keeping the planing element taut. The facing device incorporates an electrical power system which conducts electrical current from an external source, through an electrical power unit, through a safety switch, through the wire planing element, to the frame and earth ground which are electrically interconnected. The current flow heats the wire planing element and enables it to shear a flat polystyrene panel. Guide arms capable of resting on and following the flat panel are incorporated into the frame, and the tension arms and wire planing element are so attached to the guide arms that the wire planing element follows the path of the guide arms leaving a flat smooth surface.Type: GrantFiled: September 2, 1987Date of Patent: March 7, 1989Assignee: Rayco, Inc.Inventors: W. Earl Dove, E. Ray Cotten

Patent number: 4798934Abstract: A hand-held electrically heated tool for applying heat to an object includes an elongated metallic tubular handle open at its forward and rear ends and having a plurality of raised relatively-spaced longitudinally extending vanes formed on its the inner surface and extending between the forward and rear ends thereof. An exposed metal electrical resistance heating element forming a wire tip is mounted in an insulator disposed in the forward end of the handle in engagement with the vanes with the tip extending forwardly of the handle. A spherically concave portion of the insulator reflects heat away from the handle.Type: GrantFiled: April 22, 1986Date of Patent: January 17, 1989Inventor: Robert E. Boyer

Patent number: 4797999Abstract: A cutting head member for rigidly retaining the substantially U-shaped cutting blade of a resistance-heated tire groover is disclosed. The preferred embodiment enables the rapid and efficient adjustment or replacement of the substantially U-shaped cutting blade without the use of a wrench, screwdriver, or other working tool. A resistance-heated tire groover using the described cutting head member also is disclosed. The preferred embodiment provides precise control and regulation of the generation of heat in the substantially U-shaped cutting blade without interrupting or altering a grooving operation.Type: GrantFiled: September 11, 1987Date of Patent: January 17, 1989Inventor: Guy A. Van Alstine

Patent number: 4690724Abstract: A portable decal stripping tool particularly adapted for the quick removal of adhesive decals from an automotive surface and comprising a decal stripper attachment for a soldering iron including an elongate shaft with a head portion secured thereto adapted to removably engage and support a razor blade. The decal stripper attachment is constructed of heat conductive material which facilitates elevation of the temperature of the razor blade secured therein so that it will slide under and remove a decal by melting the adhesive securing it to an automobile surface or the like.Type: GrantFiled: April 24, 1986Date of Patent: September 1, 1987Inventor: William F. Outlaw

Patent number: 4650961Abstract: A wirestripper for thermal stripping a length of insulated wire includes a "V"-shaped flat metal strip of nickel chrome alloy 0.2 mm thick and having first and second arms 1 mm wide and 3.2 cm long extending from a vertex. The "V"-shaped strip is supported between a support post at the vertex and a respective electrode post at the end of each of the arms, with the electrode posts and support post being parallel and biased apart to tension the "V"-shaped strip. The electrode posts are spaced apart a sufficient distance to permit the length of wire to be stripped to be passed laterally therebetween and between the first and second arms into the vertex for stripping. The serial resistance of the "V"-shaped strip between the electrode posts sufficient for energization of the strip by a 1.2 volt battery connected to the electrode posts.Type: GrantFiled: April 22, 1985Date of Patent: March 17, 1987Inventor: Tony Nespor
