Patent number: 7930977Abstract: Non-lethal ammunition for a riot gun assembles a bi-chambered projectile body and an impact nose, the assembly being spin-stabilized and nose-heavy such that the nose will impact first at the target. The rearward end of the assembly is mounted into the forward end of a shell casing having a high-energy gas expansion chamber, the mounting forming a low-pressure chamber at the rearward end of the projectile. A cup-shaped multi-port gas diffuser plug, spaced from the projectile body, directs burnt propellant gases from the expansion chamber into the low-pressure chamber to expel the projectile at a relatively low velocity. A sleeve interiorly of the gas diffuser plug closes the ports and is degraded by the burnt gases to provide a complete burning of the propellant.Type: GrantFiled: February 26, 2008Date of Patent: April 26, 2011Inventor: John M.

Publication number: 20070137085Abstract: Firearms are used for self defense and sport. Self defense requires immediate access to a loaded firearm. A safety cartridge is designed to prevent an unauthorized person from firing a loaded pistol, revolver, rifle, or shotgun. The safety cartridge is placed in the firing chamber of a loaded firearm containing live ammunition. The firearm owner may quickly use his weapon for self defense or in a police action by ejecting the safety cartridge or by rotating the cylinder. An attempt to fire the loaded firearm by an unauthorized person initiates the safety cartridge causing the resulting primer gases to propel the slug down the gun barrel until it is stopped by action of the spring which is attached to both the cartridge case and the slug causing it to jam preventing injury to the firearm owner or children. Removing the fired safety cartridge requires skill.Type: ApplicationFiled: November 24, 2006Publication date: June 21, 2007Inventor: Robert Len Aske

Patent number: 6752086Abstract: An anti-personnel projectile launched from a weapon shell required at impact to have a low lethality consequence, in which the projectile is fitted in the shell in a shape characterized by a blunt end in the direction of flight and maintained in this shape by oppositely directed air resistance and propelling forces to obviate a change of shape during flight that might cause a serious injury.Type: GrantFiled: November 21, 2002Date of Patent: June 22, 2004Inventors: Jacob Kravel, Michael Brunn

Patent number: 6736070Abstract: A specialty bullet is disclosed that is adapted to transmit a tranquilizing fluid upon impact with a target for purposes of immobilizing the intended target without causing great harm to the target or the surrounding area. The specialty bullet is sized and shaped like that of a conventional bullet so that it can be fired from a conventional firearm; however, the concept could work with innumerable types of ammunition. The disclosed invention includes a so-called “Collapsule” bullet, which is a molded, hollow cavity fabricated of a high-strength malleable plastic polymer that is filled with a tranquilizing fluid. The bullet is fitted with a so-called “Injectile,” which is a hypodermic injection spike (to transmit the tranquilizing fluid) that is backed and driven by an inertia base mass (i.e., lead core or other suitable) located at the base of the bullet.Type: GrantFiled: February 20, 2003Date of Patent: May 18, 2004Inventor: Joseph C. Baltos

Patent number: 6625916Abstract: A training kit is designed for use with a firearm normally having a standard bolt that is provided at the forward end with a bolt recess for receiving and embracing the head end of a standard cartridge. The training kit is provided with a training bolt having a circular recess of a diameter that will not receive and embrace the head end of the standard cartridge thereby limiting placement of a standard cartridge beyond the reach of the firing pin. Rounds of reduced-energy training ammunition are provided with a head end of complementary dimensions that permits the head end to be seated within the recess of a conversion bolt, and therefore fired.Type: GrantFiled: November 4, 1999Date of Patent: September 30, 2003Assignee: SNC Technologies Inc.Inventor: Sylvain Dionne

Patent number: 6626113Abstract: A long-range training cartridge meets current US Army requirements. The long-range cartridge design enables its sub-projectile to be range limited to less than 8000 meters when fired at a 10-degree gun elevation. The long-range training projectile includes a three-piece aluminum or steel sabot with a similar exterior profile to the kinetic energy tactical sabot. The sabot encapsulates a light-weight sub-projectile comprised of a steel rod and an aluminum fin or cone. Since the sub-projectile is encapsulated in the sabot, it will not be subjected to differential pressures associated with interior ballistic gun gasses. As a result the sub-projectile will therefore have less bending and better flight characteristics. The sub-projectile meets the guidelines for target accuracy and precision at ranges beyond 3000 meters.Type: GrantFiled: August 13, 2002Date of Patent: September 30, 2003Assignee: The United States of America as represented by the Secretary of the ArmyInventors: Stewart Gilman, Leon R. Manole, Francis Renner, Anthony P. Farina

Patent number: 6619211Abstract: A practice ammunition projectile comprises a head which bursts when the projectile strikes a target and contains a marking agent which optically indicates the point of impact after the head has burst. The marking agent consists of several chemical components (7, 8) which are each contained in separately breakable compartments (4, 5) within a burstable hood at the head of the projectile. When the compartments (4, 5) break open the components combine and undergo a chemical reaction which creates an optical mark. The hood is formed of an optically transparent material to enable the trajectory of the projectile to be tracked.Type: GrantFiled: January 29, 2002Date of Patent: September 16, 2003Assignee: Nico-Pyrotechnik Hanns-Juergen Diederichs GmbH & Co. KGInventor: Ted Haeselich

Patent number: 6615739Abstract: The invention provides aerodynamic projectiles that include a projectile shell having an aerodynamic structure and a controlled center of gravity, which exhibit improved aerodynamics and resulting accuracy, and which are suitable for non-lethal uses. Methods of making such aerodynamic projectiles also are provided.Type: GrantFiled: April 5, 2001Date of Patent: September 9, 2003Assignee: Perfect Circle Paintball, Inc.Inventors: Gary E. Gibson, Michael A. Varacins
