A retention system protects the round stored inside a rotating continuous belt-type magazine, and holds the round securely while allowing it to be readily and easily released prior to firing. The retention system permits all the retaining devices to be easily retracted so that a ramming mechanism of the weapon can push the round into the chamber without interference. The gun tube of the automated weapon houses the round and provides interfaces for all other components to attach. The tube length minimizes the axial movement of the round. The round is held within the tube by a front door assembly and a rear door assembly. The door assembly is made of a crescent-shaped door attached to a pivot shaft, in order to minimize the amount of rotational travel required to open the door for loading or firing the round.

A firing abort and hang fire safety system for a small or medium caliber multi-barrel automatic weapon includes a device to immobilize the revolving assembly (100) of the weapon in rotation. This device includes a shock-absorbing device mounted coaxially to the revolving unit of the weapon, a control device integral in rotation with the revolving unit and able to translate, further to the misfire of a round of ammunition or to the activation of an external control, to compress the shock-absorbing means device and absorb the rotational kinetic energy of the revolving unit of the weapon. The backspring of the shock-absorbing means device thereafter causing the revolving unit of the weapon to rotate in the opposite direction before stopping.

Control and safety device for an externally powered automatic weapon include at least one rotor driven by a motor and have a stop cooperating with a locking part. The device has both a detent lever to control firing and a second lever subjected to the action of a rotating finger driven by the recoil of the weapon. The detent lever and the second lever are connected to the locking part by a system of slides and links which automatically stop the rotor by way of the locking part if ammunition should malfunction.

A hangfire protection system for an externally powered gun includes a recoil sensing mechanism cooperating with a sear latching mechanism such that in the event of a hangfire, a sear engages a safety link on the chain drive assembly to keep the bolt locked. If the round fires, gun function continues; if the round does not fire there is a delay of a sufficient time to assure that the round is a dud, and it is ejected. The details of the mechanical hangfire protection system are described.

An emergency stop device for a weapon with a drive for transporting a breech block of the weapon. At least one guide, at least one connecting rod guided in the guide, and at least one lever are provided. When a shot is not being fired, the kinematic system is deactivated. When a shot is being fired, the at least one guide is moved rearwards, and the at least one connecting rod is guided upwards along the guide such that the lever exerts a lever movement, by means of which the transport of the breech block is made possible. The weapon drive has a complete control slide for transporting the breech block of the weapon. A bolt is laterally embedded in the transverse slide, said bolt being integrated below the complete control slide of the drive in a movable manner in the slide.

A safety device for a front-loading weapon of the type comprising a mortar barrel having a closed breech end and an opposite open end for launching a mortar projectile. The device includes at least one sensor, configured for mounting adjacent the mortar barrel, for sensing a mortar projectile upon its insertion in the barrel and an electronic circuit, coupled to said sensor, for detecting movement of the mortar projectile past said sensor, thereby to detect the presence of the projectile in the barrel.

This invention relates to an arrangement for rapidly stopping an automatic weapon having an external drive where the breech block is driven by parallel shafts. This arrangement provides for the rapid stopping of the shafts and thus the weapon by providing the shafts with coaxially mounted pockets at their ends in which a pair of claws may be engaged to stop the rotation of the shafts.

In weapons in the nature of a Gatling gun the danger exists with an ignition delay or hangfire that the cartridge still is ignited after the positively reciprocated breechblock has been unlocked. However, cartridge ignition is undesired after unlocking of the breechblock. Therefore, an apparatus is present with the invention preventing unlocking of the breechblock in case of an ignition delay. Such safety apparatus may respond to (a) the gas pressure, (b) the weapon recoil, (c) the forward advance of the weapon or (d) to an expansion or bulge formed in a cartridge case, and acts to separate a breechblock head from a breechblock carrier, the breechblock head remaining in its locked position.The apparatus comprises either an inertia mass displaced relative to the breechblock due to the recoil action or a cam plate mounted at the weapon cradle and responding to the forward advance of the weapon, or a feeler pin responsive to an expansion or bulge formed in the cartridge case. The apparatus may cause a deflection of a cam follower roll from a first control cam into a second control cam, whereby the breechblock remains in its locked position.

This disclosure relates to an automatic weapon having a breech mechanism driven in reciprocation by an external motor and equipped with a device to keep the breech mechanism from moving from the advanced or forward locked position in case of a hangfire. If a "shot departure" sensor fails to sense the departure of a shot a spring projects bolts into the path of the breech mechanism and locks it at the start of its recoil stroke.
