Patent number: 8468946Abstract: A modified 40 mm grenade round designed to breach doors without throwing a significant amount of shrapnel into a building's interior or back toward the shooter. The modified round includes a forward extension on the ogive. The extension is rigidly connected to a thrust column which transmits an impact load directly from the ogive's nose cap to the striker on the fuse assembly. This configuration detonates the explosive charge within the projectile while the explosive is still well outside the door. This early detonation throws a pressure wave again the door's exterior, forcing the door inward.Type: GrantFiled: March 24, 2011Date of Patent: June 25, 2013Assignee: Chemring Ordnance, Inc.Inventors: Bruce G. Van Stratum, James P. Muncie, Matthew E. Eckel

Patent number: 8413586Abstract: A modified 40 mm grenade round designed to breach doors without throwing a substantial amount of shrapnel into a building's interior. The modified round includes a standoff device located on its forward end. The standoff device detonates the explosive charge within the projectile before the nose of the projectile actually strikes the target. This early detonation throws a pressure wave again the door's exterior, forcing the door inward. Shrapnel produced by the detonation remains primarily outside the door. Thus, the modified projectile is able to blow open a door without throwing a significant amount of shrapnel into a building's interior.Type: GrantFiled: January 19, 2010Date of Patent: April 9, 2013Assignee: Chemring Ordnance, Inc.Inventor: Bruce G. Van Stratum

Patent number: 7191707Abstract: The spherical rolling explosive ordnance is a bomb having a substantially spherical shaped structure that includes a hard outer shell and a shock absorbing outer layer. The spherical shaped structure has a hollow inner core that is symmetrically disposed about an axial center of the structure. Within the hollow inner core are a plurality of mutually orthogonal motion sensors and a computing device. The sensors are electrically coupled to the computing device which accepts sensor outputs to process a plurality of motion profile samples. An explosive charge is distributed between the shell and the core. A fuse mechanism within the explosive charge is electrically coupled to a primary arming device. The primary arming device is armed responsive to the predetermined criteria of the motion profile samples. Arming the arming device causes the fuse to be ignited to provide detonation of the ordnance device.Type: GrantFiled: November 15, 2005Date of Patent: March 20, 2007Inventor: Russell J. Davis

Patent number: 6279480Abstract: A firing pin assembly for mechanically igniting a warhead detonator of a projectile by being accelerated in a forward direction by inertia upon impact, includes a firing pin having a rearward firing pin part and a frontal firing pin part arranged in series with the rearward firing pin part as viewed in the forward direction. The assembly further has a firing pin spring urging the firing pin in a direction opposite to the forward direction, and a mechanical device positioned between the rearward firing pin part and the frontal firing pin part. The mechanical device includes a transmission arrangement for transmitting a forward motion of the rearward firing pin part to the frontal firing pin part with a stepped up transmission ratio whereby a forward motion of the rearward firing pin part through a first distance results in a forward motion of the frontal firing pin part, against the force of the firing pin spring, through a second distance which is greater than the first distance.Type: GrantFiled: October 21, 1999Date of Patent: August 28, 2001Assignee: Rheinmetall W & M GmbHInventor: Karlheinz Roosmann

Patent number: 4964469Abstract: Disclosed is a device which, upon impact, will broadcast a dry material such as fire-suppressing chemicals by explosive force. The device comprises an explosive charge within a frangible rigid-wall container, a dry powder payload within the container which substantially surrounds the explosive charge, and a fuse cord operably positioned between the explosive charge and an impact-activated detonator. Upon impact, the detonator will cause the fuse to be ignited. Ignition of the fuse cord, whether by the impact-activated detonator or an external source, will cause detonation of the explosive charge, thereby breaking the container and broadcasting the dry material outwardly therefrom.Type: GrantFiled: February 21, 1990Date of Patent: October 23, 1990Inventor: Wayne D. Smith

Patent number: 4760794Abstract: An explosive small arms projectile is disclosed. Prior art projectiles of this kind include a lead core for increased mass which core is formed with a blind hole for receiving an explosive and the necessary detonating device.The projectile of the invention comprises a jacket (102) of a metal with a specific gravity in excess of 13, Tantalum or a Tantalum/Tungsten alloy being preferred. The entire interior of the jacket is left free for the explosive charge; the jacket (102) has increased mechanical, structural and tensile characteristics over prior art projectiles and the projectile has better rotational ballistic stability in use due to the redistribution of the mass thereof to the periphery.Type: GrantFiled: April 21, 1982Date of Patent: August 2, 1988Inventor: Norman Allen
