David Lewis Lofton has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8074864
    Abstract: An ignition source system for an exothermic reaction mold device for welding conductors. The system includes a crucible in a block with an open top so that the crucible receives an exothermic weld material. The conductors to be welded exothermically are placed in the weld cavity of the mold. A lid covers the open top wherein the lid has an opening therethrough. An electronic thermal igniter assembly has an ignition component receivable through the opening in the lid so that the exothermic weld material may be ignited by the electronic thermal igniter assembly. The igniter plug rests on top of the lid and the ignition body is retained in a recess within the igniter plug.
    Type: Grant

  • Publication number: 20110132966
    Abstract: An alternative ignition source system for an exothermic reaction mold device for welding conductors. The system includes a crucible in a block with an open top so that the crucible receives an exothermic weld material. The conductors to be welded exothermically are placed in the weld cavity of the mold. A lid covers the open top wherein the lid has a opening therethrough. An electronic thermal igniter assembly has an ignition component receivable through the opening in the lid so that the exothermic weld material may be ignited either by the electronic thermal igniter assembly or may be ignited by a spark.

  • Patent number: 7240717
    Abstract: A multiple ignition source exothermic reaction mold device. The mold device includes a crucible in a block with an open top for receiving exothermic reaction powder. A lid covering the open top has an opening therethrough. A receptacle in the lid is in communication with the opening so that the receptacle receives starting powder. The starting powder and, in turn, the exothermic weld material is ignited by alternate sources, either by a spark from an ignitor device or by an electric supply sent through an ignitor element.
