Ammunition storage and feeding system
11674766 · 2023-06-13 · ·

Ammunition storage and feeding system for light weapons that facilitates a continuous loading of the weapon, thereby relieving the user from multiple magazine replacements, and reducing potential weapon stoppages, thus providing more reliable and significantly uninterruptable use of the weapon with respect to operating the weapon with conventional magazines. According to an embodiment of the invention, the system is configured to automatically receive interlinked cartridges from a carrying device (e.g., a backpack or other convenient device harnessed to the user's body) through a flexible or semi-flexible leading means, to successively extract the cartridges from the linking arrangement and to successively feed each extracted cartridge into a dedicated magazine in a First In First Out (FIFO) manner.

ACTUATION SYSTEM FOR A FIREARM

An actuation system includes a breechblock assembly, and a slide whereon the breechblock assembly is mounted. The slide is configured to slide linearly on a linear guide. A cylindrical cam is configured to be rotatably actuated by a motor and cooperating with the slide for controlling movement along the linear guide. The outer surface of the cam defines a path having a first parking section, a second parking section, a forward intermediate section and a backward intermediate section connecting the first annular parking section and the second annular parking section. The slide is moved forward from the first operating position to the second operating position and, respectively, backward from the second operating position to the first operating position.

Method for operating gun having multi-drive link feed system
10921074 · 2021-02-16 · ·

A method of feeding rounds of linked, or un-linked, ammunition to a gun includes a motor-driven chain drive which rotates about a track. A rotatable feeder engages the ammunition to feed an ammunition round into a round extractor/retractor. A rotatable round positioner receives an ammunition round from the round extractor/retractor, and rotates it to a firing position. A main geneva wheel, mounted near the chain drive, is sequentially engaged by first and second drive rollers, secured to the chain drive, for being periodically rotated thereby. Drive pins of the main geneva wheel sequentially engage radial slots in a belt/round feed geneva wheel and a round positioning geneva wheel for timed rotation thereof to synchronize the operation of the round feeder and round positioner.

Ammunition monitoring apparatus, self-propelled artillery, and ammunition carrier

An ammunition monitoring apparatus of the present disclosure includes at least one object-position detection sensor and a controller. The at least one object-position detection sensor is installed near a shell or charge route to face at least one set area and to output position information of each shell or charge in the at least one set area. The controller is configured to determine whether a position range occupied by the shell or the charge in the at least one set area exceeds an allowable position range, based on the position information received from the at least one object-position detection sensor, and to output an alert signal indicating a poor position upon determining that the position range occupied by the shell or the charge in the at least one set area exceeds the allowable position range.

Cartridge for cooling gun barrels

A liquid or powder filled cartridge is used to cool and lubricate the bore of gun barrels to eliminate cook off and improve barrel life. A primer is used to rupture the nose of the cartridge and propel the cooling material into the bore. The coolant absorbs heat from the bore of the barrel and is ejected from the muzzle of the weapon. The liquid or powder may include lubricants, preservatives, antifreeze, coolants, cleaners, or mixtures thereof, or other materials to enhance barrel performance. The liquid or powder filled cartridge is particularly well suited to externally powered weapons. Ammunition may be fed into the weapon using a mix of conventional cartridges and coolant filled cartridges. Internally cooling the barrel may be used to reduce or eliminate cook off and increase barrel life.
