The pendulum weight is arranged on the trigger in such a manner that it can pivot about a pivot axis that is located, viewed in the direction of firing, in front of the trigger axis, and the center of gravity of the pendulum weight is located above the trigger axis.

Abstract: This invention provides a handgun assembly such as a rifle (9) which has a barrel assembly (24) including a cluster of barrels each supporting a longitudinal arrangement of aerodynamically shaped, directional projectiles (15) and interposed propellant charges (16) whereby the barrel assembly has longitudinal arrays or layers or projectiles and interposed propellant charges. Ignition means is provided for selectively igniting the propellant charges (16) including for simultaneously igniting the propellant charges in the leading layer of projectiles to provide a shotgun-like blast.

Abstract: A barrel assembly (70) comprising a plurality of projectiles (75) axially disposed within a barrel (71) and associated with discrete selectively ignitable propellant charges (74) for propelling the projectiles from the barrel. The essence of the invention is the provision of a pressure relief valve, for example comprised by a port (73) and plug (76), associated with a chamber in which a propellant charge (74) is ignited. The pressure relief valve (73, 76) is designed to prevent catastrophic failure of the barrel (71) by exhausting via a chamber (72) in the event that the barrel is blocked by a projectile and detonation of one or more propellant charges (74) occurs.

Abstract: A two-barrel gun for firing two types of ammunition includes a single breech locking mechanism for both barrels. The gun includes a selector lever for activating one of two bolts associated with the two barrels, and a single trigger for firing ammunition from a chamber associated with the activated bolt. The gun further includes two magazines for feeding ammunition to the chambers, and a pump-action forearm for ejecting spent ammunition and for loading a new round of ammunition into the chamber associated with the activated bolt. The single breech locking mechanism extends forwardly of the chambers, and the actual breech locking engagement occurs in front of the bolts. Therefore, the receiver section of the gun can be made more compact, and can more easily accommodate other essential components.

Abstract: In the case of a twin-barrelled firing weapon, the apparatus for delivering ammunition from a container structure to the firing weapon is located between the two weapon barrels of the firing weapon. In order to accommodate or store as much ammunition as possible in the space between the two weapon barrels, the cartridges are arranged not only side by side but also one behind the other. There is provided as the container structure a first front container from which cartridges are delivered to one weapon barrel and a second rear container from which cartridges are delivered to the other weapon barrel. The cartridges from one of the two containers are delivered to the related weapon barrel by a device for axially displacing the cartridges.

Abstract: A cartridge feeder for a gun having two alternately fired barrels has respective adjacent loading positions. The feeder comprises a guide defining a path having an upstream end and a downstream end, the latter being at one of the positions and the other position being between the downstream and the upstream end. Cartridges are movable in a row along the path and are laterally displaceable out of the path at the positions, so they can be chambered directly from this path. A sprocket at an upstream end of the path is rotated while in engagement with a sequence of cartridges to advance same into the upstream end and thereby push the cartridges along the path into the positions. The feeder can be formed in part by an endless flexible conveyor having a stretch extending along the path opposite the barrels and formed with a succession of cartridge-engaging holders.

Abstract: A gun with two barrels of different calibers wherein both barrels have a repeater mechanism, manual or automatic, and wherein the weapon has a barrel-selector mechanism which selectively, as desired, brings one barrel into an operative state while at the same time putting the other barrel in an inoperative state. The breech block for the respective barrels are joined together via a cam on the breech block, such that the two breech blocks together constitute a cam mechanism which permits movement of the other breech block toward and away from the first breech block transversely of the barrels, and that the two breech blocks, during repeater-action of the weapon, move together and in parallel in the longitudinal direction of the barrels. The interconnected breech blocks thus together and synchronously lock the two breech blocks in their forward positions.

Abstract: A rotary pneumatic motor provides initial acceleration and starting of a rapid firing gatling-type gun, and also provides motive drive power for the gun in another embodiment. Upon reaching operating speed, a fluidic control system modulates application of a disc brake and/or meters fluid flow to the rotary motor to maintain a constant preselected firing rate. After completion of gun firing, the rotary motor briefly drives the gun to clear the chambers of ammunition.

Abstract: A gun drive system is provided wherein recoil motion is used to pump hydraulic liquid into an accumulator, which in turn, on demand, drives a hydraulic motor and the thereto coupled gun, discharging into a low pressure reservoir, which in turn, resupplies the pump chamber upon counter-recoil motion.
