Thomas M. McCoig 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).

  • Non-lead, environmentally safe projectiles and explosives containers
    Patent number: 6174494
    Abstract: A solid object having controlled frangibility, such as a bullet or a container for explosives, is made by combining two different metals in proportions calculated to achieve a desired density, without using lead. A wetting material is deposited on the base constituent which is made of a relative dense, hard material. The wetting material enhances the wettability of the base constituent with the binder constituent, which is lighter and softer than the base constituent.
    Type: Grant
    Filed: March 20, 1998
    Date of Patent: January 16, 2001
    Assignee: Lockheed Martin Energy Systems, Inc.
    Inventors: Richard A. Lowden, Thomas M. McCoig, Joseph B. Dooley, Cyrus M. Smith
  • Non-lead, environmentally safe projectiles and method of making same
    Patent number: 6149705
    Abstract: A projectile, such as a bullet, is made by combining two different metals in proportions calculated to achieve a desired density, without using lead. A base constituent, made of a material having density greater than lead, is combined with a binder constituent having less density. The binder constituent is malleable and ductile metallic phase material that forms projectile shapes when subjected to a consolidation force, such as compression. The metal constituents can be selected, rationed, and consolidated to achieve desired frangibility characteristics.
    Type: Grant

    Date of Patent: November 21, 2000
    Assignee: UT-Battelle, LLC
    Inventors: Richard A. Lowden, Thomas M. McCoig, Joseph B. Dooley
