Patent number: 7779740Abstract: A revolving firing pin system is mechanically linked to a screw-block in a breech-loading mortar system, wherein the revolver firing pin assembly rotates on a centerline that is offset from the centerline of the screw-block assembly. When the revolver firing pin assembly is rotated, the firing pin assembly also rotates. However, until the screw-block assembly is locked, the firing pin is in a safety position that is not in line with the primer of the munition loaded into the mortar system. Only when the screw-block is rotated into a locked position does the firing pin align with the primer of the munition to thus be able to strike the primer when the solenoid is electronically actuated.Type: GrantFiled: January 10, 2008Date of Patent: August 24, 2010Assignee: The United States of America as represented by the Secretary of the ArmyInventors: Edward Holmes, Lee Bennett, Donald Forkas, George Hathaway, IV

Patent number: 7270060Abstract: A rod sleeve made of smart material sleeves and/or steel sleeves with smart material rings surrounds the rod of a kinetic energy projectile. The rod may be made of DU, tungsten, or other material. Smart materials are materials such as nickel-titanium (nitinol) and copper aluminum nickel (CAN) that can be trained to change to one or more particular shapes at predetermined temperatures. The change in shape occurs on a molecular level, almost instantaneously. The rod sleeve can be made all or in part from smart material. The smart material is trained to shrink at cold temperatures and expand at hot temperatures. The sleeve may then be heated and expanded to allow the sleeve to be pressed on the rod. As the sleeve cools, it compresses and provides required support to rod during gun launch of the kinetic energy projectile. The sleeve heats up while traveling down range due to the aero-ballistic heating of the sleeve material. At this higher temperature, the sleeve expands.Type: GrantFiled: September 5, 2003Date of Patent: September 18, 2007Assignee: United States of America as Represented by the Secretary of the ArmyInventors: Leon Manole, Stewart Gilman, Ernest Logsdon, Daniel Vo

Patent number: 7258055Abstract: A machine gun mount is provided for mounting a machine gun in a movable support arm of a helicopter. The mount includes a gun cradle which is detachably connected to the gun and a pintle one end of which is adapted to pivotably mount the pintle, and thus the mount, on the movable support arm. This enables pivoting movement of the gun in a horizontal plane. The pintle is pivotably connected at the opposite end to the cradle so as to permit the cradle, and thus the gun, to be rotated in a vertical plane through 90 degrees between operative and stowed positions. A locking mechanism locks the cradle in the stowed position. A magazine is attached to one side of the cradle while a spent case and link frame and associated catch bag are attached to the opposite side. The magazine includes an inwardly projecting portion disposed below the cradle.Type: GrantFiled: April 8, 2004Date of Patent: August 21, 2007Assignee: United States of America as Represented by the Secretary of the ArmyInventor: David Javorsky

Patent number: 7207276Abstract: A non-lethal ammunition utilizes dense powder ballast and a two-stage firing sequence for launching non-lethal projectiles of a caliber range from approximately 5.56 mm through approximately 40 mm. The non-lethal ammunition comprises a non-lethal cartridge. The non-lethal cartridge comprises a dense powder ballast and one or more non-lethal projectiles. The dense powder ballast is more massive than the non-lethal projectile providing sufficient payload mass to operate the weapon mechanism while launching the non-lethal projectile at velocities compatible with non-lethal applications. A two-stage ignition system fires the non-lethal ammunition and subsequently fires the more massive dense powder ballast. The firing events are separated by a time delay of less than a second. The non-lethal ammunition provides non-lethal projectile capability for semi-automatic and automatic weapons.Type: GrantFiled: August 25, 2004Date of Patent: April 24, 2007Assignee: United States of America as represented by the Secretary of the ArmyInventor: Frank Dindl
