Patent number: 11703302Abstract: A dynamic sealing chamber magazine for an air gun carries multiple projectiles for the air gun and sequentially places each projectile in line with the bore of the gun while serving as a chamber for the projectile and gun. Each chamber of the magazine is configured to temporarily seal to an air orifice and barrel bore of the air gun upon firing. Each chamber includes a hole and two tubular sleeves therein. A pressurized gas released into a chamber when the chamber is aligned with the air orifice and barrel bore and the gun is fired pushes the sleeves apart from inside the chamber and compresses the sleeves into sealing engagement with opposing breech surfaces of the gun surrounding the air orifice and barrel bore. The sleeves decompress, unseal, and retract to a static position when the gas pressure decreases below the elastic potential energy of the sleeves.Type: GrantFiled: August 23, 2022Date of Patent: July 18, 2023Assignee: UMAREX USA, INC.Inventors: Alexander Robert DiBlasio, Stephen R.

Patent number: 11187509Abstract: A projectile for loading into a rifled barrel includes a casing having a cylindrical body, a forward aerodynamic end, and a free end opposite the aerodynamic end, the cylindrical body of the casing defining an interior cavity extending to and in open communication with the free end. The projectile also has a bullet sized to initially slidably engage the casing along a partial length of the interior cavity through the free end. Upon discharge of propellant, the bullet is forced to slidably engage the casing farther within the cavity, preferably such that an entire length of the bullet is housed within the casing cavity, whereby a circumference of the casing is increased such that the increased circumference of the casing catches barrel rifling of the muzzleloader rifle. This allows a smaller caliber bullet to be used in a fouled barrel, while increasing accuracy of the muzzleloader rifle.Type: GrantFiled: December 2, 2020Date of Patent: November 30, 2021Inventor: Chris Lee Billings

Patent number: 8297187Abstract: A marking projectile comprises separate compartments that break during launch due to rotation of the projectile as it leaves the barrel of a weapon. Metal pellets contained within the compartments are pressed outward and pierce the compartment walls. This allows for mixing of chemical materials contained within the compartments, so that the materials substantially react by the time the projectile strikes a target. The chemical materials may be a pair of chemi-luminescent components, or components that create heat for thermal marking.Type: GrantFiled: July 12, 2010Date of Patent: October 30, 2012Assignee: Rheinmetall Waffe Munition GmbHInventor: Kevin Michael Sullivan

Patent number: 8191480Abstract: A method and apparatus for expelling a projection from an air gun by striking a primer cap filled with a shock-sensitive explosive compound, causing the cap to explode, which in turn rapidly compresses a volume of air located between the projectile and the cap, causing the projectile to exit from the barrel of the air gun at a high rate of speed.Type: GrantFiled: February 5, 2007Date of Patent: June 5, 2012Assignee: GunsandMore.Info LLCInventor: Chris Mcaninch

Publication number: 20120085259Abstract: A cartridge that can fire a light-weighted projectile, producing a pressure curve of the propellant gases similar to the pressure curve generated by the shot of a heavy weighted lead-core projectile. The cartridge propels the light-weighted projectile together with a capsule, which contains an inert load of high density metal powder. The capsule is divided in multiple parts, which disassemble when it leaves the firearm muzzle, spreading the metal powder in the air. The metal powder increases the mass which is accelerated by the propellant gases, keeping the pressure curve high enough to cycle a self-loading firearm mechanism. The metal powder consists of very thin particles which spreads and decelerates rapidly in the air, causing a controllable level of danger to personnel.Type: ApplicationFiled: October 12, 2010Publication date: April 12, 2012Inventor: Pedro de Oliveira Cronemberger

Publication number: 20120017793Abstract: A two piece, two-stage, rechargeable, reusable, reduced-energy mechanically operating cartridge is provided for launching a bullet of various compositions from a dedicated or modified firearm. The cartridge unit is comprised of a primary case, a piston sleeve, a propellant unit, and a bullet choice of a solid light weight material for inanimate-target applications or a “marking” version for non-lethal live-target training applications. Cartridge includes a piston sleeve and a primary case coupled together via a channel and cog locking/traveling/unlocking system. The primary case includes a substantially non-deformable jacket defining a cavity to receive a propellant unit or propellant connection and provides the channels to receive piston sleeves cogs for a locking/traveling/unlocking feature. The piston sleeve includes a substantially non-deformable jacket defining a cavity to receive configured bullet.Type: ApplicationFiled: July 25, 2011Publication date: January 26, 2012Applicant: FEDERAL CARTRIDGE COMPANYInventor: Rick Huffman

Patent number: 8061274Abstract: A less than lethal projectile and method of producing the same comprising of a sealed filled polymeric pouch containing a shot within. The sealed filled polymeric pouch is formed in a form, fill, and seal machine. An automatic loading ammunition machine is fed empty shell casings; the ammunition machine automatically loads the empty shell casing with pre-determined quantities of wad, primer, and gun powder, and subsequently moves the sealed filled polymeric pouch into a projectile compartment of the empty shell casing producing a fully-loaded shell casing to be loaded into a barrel of an ammunition. The polymeric pouch is capable of being inserted into various shell casings depending on the intended use thus allowing for officers and soldiers to select from an array of munitions when confronted with a situation where less than lethal means are required.Type: GrantFiled: January 26, 2009Date of Patent: November 22, 2011Assignee: Brejon Holdings (BVI), Ltd.Inventors: John Hayes, Daniel Smith
