Patent number: 8869701Abstract: The present invention describes an improved cartridged projectile (100). The cartridged projectile (100) comprises a projectile (110) seating at a mouth of a cartridge case (130). The cartridge case (130) has a base (134) that houses a high pressure chamber (150). A side of the high pressure chamber (150) is capped by a pressure disc (170), which is secured onto the base of the cartridge case by a nozzle ring (160). The nozzle ring (160) has a tapered or conical surface that allows the pressure disc (170) to flex, and a surface (171) of the pressure disc (170) exterior of the high pressure chamber has intersecting V-shaped grooves (172). When propellant in the high pressure chamber (150) is burned efficiently, high pressure gases developing inside the high pressure chamber cause the pressure disc (170) to rupture at a predetermined pressure along the grooves (172) so that the gases propel the projectile (110) out of a barrel at a higher speed of about 100 m/s or more.Type: GrantFiled: September 26, 2011Date of Patent: October 28, 2014Assignee: Advanced Material Engineering Pte LtdInventors: Cheng Hok Aw, Chee Keong Yak, Soo Chew Sie, Renjie Xie

Patent number: 8794155Abstract: A system includes an incomplete cartridge for a firearm and a field-selectable capsule for the cartridge. The capsule contains a product that may tag a person for tracing, induce sleep, cause disease, or have other effects. Capsules are preferably removably adhered to a strip with each strip of capsules potentially serving a different purpose. The incomplete cartridge includes a bullet that has an opening at the payload end. The opening receives and retains a capsule upon insertion. The capsule is made of a frangible material that releases the product upon impact. The capsule may be formed with a snap-in ridge extending from its exterior wall, which snaps into a complementary recess in the bullet opening. Alternatively, the capsule may be coated with a contact adhesive so that it sticks to the bullet wall defining the opening. A peel-off covering atop the strip shields the contact adhesive from contamination.Type: GrantFiled: October 11, 2013Date of Patent: August 5, 2014Assignee: HP AssociatesInventor: S. Mill Calvert

Patent number: 8783184Abstract: A cartridge for a firearm has a bullet that defines an internal chamber. The chamber has a broader top portion than a lower portion. The bullet further defines a channel passage leading out of the top end of the bullet. The bullet contains an arrowhead slidable engaged within the channel passage. A shaft is connected to the arrowhead and passes down from the arrowhead into the lower portion of the chamber. A thrust plate is connected to the shaft end in the chamber. The thrust plate is spring metal and when the cartridge is fired, the thrust plate rises pushing the arrowhead so that it extends from the leading end of the bullet. When the thrust plate rises to the second portion of the chamber, it springs open to prevent subsequent downward motion of the thrust plate and consequently prevents subsequent retraction of the arrowhead during flight and after impact.Type: GrantFiled: October 18, 2013Date of Patent: July 22, 2014Assignee: BPOB Associates, Trustee for Broadhead POB CRT TrustInventor: S.

Patent number: 8640623Abstract: A multiple-purpose projectile assembly includes an anti-personnel projectile, an armor-penetrating projectile, a propellant, a base bleed gas, and a primer. The anti-personnel projectile includes a cavity having a scored surface and is made out of a soft metal. The armor-penetrating projectile is made from a hard metal and is housed partially within the cavity of the anti-personnel projectile prior to firing from a weapon. The propellant and the primer are both housed within the cavity. The firing of the projectile assembly causes the armor-penetrating projectile to drive into the primer, thereby detonating the primer, causing the detonation of the propellant, thereby increasing the pressure of the cavity and causing the two projectiles to separate after the projectile assembly leaves the bore of the weapon. The burning of the propellant releases a base bleed gas that reduces the drag experienced by the anti-personnel projectile.Type: GrantFiled: November 17, 2011Date of Patent: February 4, 2014Inventor: Donald B.

Patent number: 8307766Abstract: A projectile includes a cartridge and a hollow bullet. A propellant fills the cartridge and the hollow bullet to increase the velocity of the bullet when fired. The hollow bullet has a flattened leading end and an annular ring is secured to the flattened leading end in the center of the flat region. The flattened leading end and the annular ring move a center of pressure forwardly so that a center of pressure is forward of a center of gravity of the bullet when the bullet is in flight. In a second embodiment, a plurality of circumferentially spaced apart slits is formed in a trailing end of the hollow bullet, creating a plurality of circumferentially spaced apart fins that flare radially outwardly upon impact with a soft target.Type: GrantFiled: May 21, 2010Date of Patent: November 13, 2012Assignee: Liberty Ammunition, Inc.Inventor: PJ Marx

Patent number: 8297190Abstract: A cartridge assembly for breaching a door including a cartridge case, a cartridge body, and a fuse. The cartridge case contains a first propellant and a primer. The cartridge body has a rearward end in locking engagement with a forward end of the cartridge case, a channel located in the cartridge body contains an extrudable explosive, a piston in slidable engagement in the channel is in a forward end of said channel, the piston being forward of the extrudable explosive contained in the channel, whereby rearward movement of the piston forces extrudable explosive rearwardly and radially outwardly through extrusion ports into a cavity inside of the cartridge body where a bladder is stowed. The piston has a rearwardly projecting detonator pin which upon movement to a rearward most position engages a rearward escapement and detonator which in turn initiates detonation of explosive in the bladder. A fuse is attached to a forward end of the cartridge body. A proximity fuse or contact fuse may be used.Type: GrantFiled: March 11, 2010Date of Patent: October 30, 2012Inventors: Frank J Dindl, Kenneth R Jones

Publication number: 20120240807Abstract: A less than lethal cartridge for a projectile which when fired has a velocity which will not kill an individual struck by the projectile. The less than lethal cartridge has a rim which is deeper or thicker than a rim on a conventional lethal cartridge. The caliber of the cartridge is also selected so that regular lethal ammunition is not available in this caliber. The preferred caliber of the less than lethal cartridge is .490. The less than lethal cartridge contains a polymeric projectile or alternatively, a sealed filled polymeric pouch containing shot therein.Type: ApplicationFiled: May 15, 2012Publication date: September 27, 2012Inventor: John Hayes
