| 20150241157 | STACKED PROJECTILE LAUNCHER AND ASSOCIATED METHODS - Provided is a barrel insert for use with a barrel containing a plurality of axially stacked projectiles. The barrel insert has a proximal and a distal end, the distal end adapted to engage a proximally disposed projectile disposed in the barrel. The barrel insert also defines an expansion volume for propellant gases for launching the proximally disposed projectile at a predetermined velocity. | 08-27-2015 |
| 20130047880 | Projectile for Use in a Barrel with a Plurality of Stacked Projectiles - A projectile for use in a barrel with stacked projectiles, particularly for a weapon which can be reloaded by a user in the field. The projectile comprises a tail assembly. The tail assembly comprises a casing and a closure in the tail assembly, the casing and closure forming a chamber containing a propellant charge, an exit from the casing for release of propellant gases into the barrel when the propellant is ignited to launch the projectile from the barrel, the closure closing the exit, wherein the closure is opened by ignition of the propellant within the chamber, a primer in a leading end of the casing, an inductor around the casing, and a signal detector at a leading end of the casing and inductor, wherein the signal detector triggers the primer and the signal detector receives a signal output from the inductor to trigger the primer. | 02-28-2013 |
| 20110290102 | STACKED PROJECTILE LAUNCHER AND ASSOCIATE METHODS - Provided is a barrel insert for use with a barrel containing a plurality of axially stacked projectiles. The barrel insert has a proximal and a distal end, the distal end adapted to engage a proximally disposed projectile disposed in the barrel. The barrel insert also defines an expansion volume for propellant gases for launching the proximally disposed projectile at a predetermined velocity. | 12-01-2011 |
| 20110277657 | Projectile for Use in a Barrel with a Plurality of Stacked Projectiles - A projectile for use in a barrel with stacked projectiles, particularly for a weapon which can be reloaded by a user in the field. The projectile includes a chamber containing a propellant charge, with an exit from the chamber for release of propulsion gases into the barrel. A seal blocks the exit and is opened by ignition of the propellant within the chamber but is resistant to gases produced by ignition of propellant in other projectiles in the barrel. The exit and seal are provided in a range of different forms. The exit may be an aperture in a wall of the chamber with the seal as a moveable barrier, such as a valve-like structure, for example. The seal may also include a rupturable or deformable barrier across the aperture. Alternatively the seal is a thin barrier around the charge such as a wax coating and the exit involves a disintegrable character of the barrier. The seal may also be an inherent property of the geometry of the chamber. | 11-17-2011 |
| 20100282111 | Propellant Sealing System for Stackable Projectiles - A projectile for use in a barrel with stacked projectiles, particularly for a weapon which can be reloaded by a user in the field. The projectile includes a chamber containing a propellant charge, with an exit from the chamber for release of propulsion gases into the barrel. A seal blocks the exit and is opened by ignition of the propellant within the chamber but is resistant to gases produced by ignition of propellant in other projectiles in the barrel. The exit and seal are provided in a range of different forms. The exit may be an aperture in a wall of the chamber with the seal as a moveable barrier, such as a valve-like structure, for example. The seal may also include a rupturable or deformable barrier across the aperture. Alternatively the seal is a thin barrier around the charge such as a wax coating and the exit involves a disintegrable character of the barrier. The seal may also be an inherent property of the geometry of the chamber. | 11-11-2010 |

| 20100043628 | Projectile for a Stacked Projectile Weapon - Clips for use with projectiles and projectile stacking systems in which individual projectiles are clipped together to form a stack are disclosed. The projectiles may be joined individually by a user before loading in a barrel, or during a loading process assisted by features on the breech of the barrel. The tail of each projectile includes a set of clips which engage the nose of a trailing projectile in the stack. Projectiles may be withdrawn from barrel and unclipped as required by the user. | 02-25-2010 |
| 20090282719 | Barrel Assembly And Projectile For Use With The Same - A barrel assembly for a weapon, said barrel assembly including a barrel; a plurality of projectile assemblies axially disposed in end to end abutting relationship within said barrel for operative sealing engagement with the bore of the barrel, each projectile including a projectile head and an integral cylindrical spacer portion extending axially and rearwardly from said projectile head; discrete propellant charges accommodated within said cylindrical spacer portion for propelling respective projectile assemblies sequentially through the muzzle of the barrel; ignition means for igniting said discrete propellant charges; and control means for selectively and sequentially actuating the ignition means. In one form, each projectile assembly further includes an internal wedging surface, at or adjacent the trailing end of said cylindrical extension which accommodates a tapered nose part of a following projectile, for expanding said trailing end into enhanced sealing engagement with the barrel upon engagement of said wedging surface With said tapered nose part. | 11-19-2009 |
| 20090241796 | PROJECTILE SEALING ARRANGEMENT - A projectile sealing arrangement for a barrel assembly of a weapon in which a plurality of projectile assemblies are axially disposed in abutting relationship within a barrel. Each projectile assembly is associated with a discrete propellant charge. The sealing arrangement includes a rearward opening communicating with a cavity provided in each projectile assembly for containing the discrete propellant charge, and a forward portion of an abutting projectile assembly arranged for operative sealing engagement with the rearward opening. During application of a compressive load to abutting projectile assemblies, the discrete propellant charge is sealed within the cavity. | 10-01-2009 |
| 20090241795 | PROJECTILES WITH SEALED PROPELLANT - Projectiles with sealed propellant are described herein. In one embodiment of the invention, a projectile includes a chamber having a propellant charger, an exit from the chamber for release of propellant gases into a barrel when the propellant is ignited to fire the projectile, and a seal to block the exit which is opened by ignition of the propellant within the chamber but is resistant to ignition of other propellant in the barrel, where the seal is carried from the barrel by the projectile after the ignition. Other methods and apparatuses are also described. | 10-01-2009 |
