81 Arrangement for stopping the moving parts of a machine cannon having an external drive US849051 1986-04-07 US4699040A 1987-10-13 Horst Menges
An arrangement for rapidly stopping the movable parts of machine cannons with independent external drives wherein a rotating element, which rotates in dependence to a rotating control drum drivingly connected to the breech block, is stopped at misfiring or delayed firing within the breech block locking period of the firing cycle by a locking element which is actuated by propellant charge gas pressure. The arrangement of the invention prevents a shock-like braking and transfer of the kinetic energy of the movable parts of the machine cannon and provides for an automatic release of the blocking element.The arrangement includes a rotating rod spring coaxially mounted within the control drum by means of which the kinetic energy of the rotating masses of the breech drive are elastically braked. Such energy transfer can even be effected with a delayed ignition because by means of positive interruption of the propellant charge gases traversing an annular chamber the release of the blocking element is prevented and it is not lifted off a cam disc. This blocking element can, however, be separately lifted of the cam disc by means of a release lever.
82 Ammunition feeding mechanism for a gun US32587 1979-04-23 US4257310A 1981-03-24 Lawrence R. Folsom; Victor R. Gardy; August J. Haberstroh
A single barrel gun has a rotary operating mechanism which is symmetrical about the longitudinal axis of the gun barrel and a feeder for ammunition.
83 Feeder for a gun US921657 1978-07-03 US4244270A 1981-01-13 Douglas P. Tassie
This invention provides for a feeder tray which is journaled for rotation on a longitudinal axis and which includes two longitudinally extending cutouts, one for receiving fresh rounds of ammunition in sequence from a constant velocity train of ammunition and for transferring each round to the face of the gun bolt in aft dwell, the other for receiving the fired case and for displacing the fired case from the face of the gun bolt, and driven by a cylindrical cam system.
84 Constant recoil system US641198 1975-12-15 US4004495A 1977-01-25 Warren B. Belfer
A mounting system for heavy caliber rapid firing weapons has a sensor ressive to gun motion during recoil. The sensor provides an electrical signal used to adjust the rate of gunfire so that counter-recoil movement of the gun upon firing each round is substantially canceled by firing the next subsequent round, whereby oscillatory shock loads transmitted through the mounting structure are greatly attenuated and converted to a relatively constant load value.
85 Modular liquid propellant gun US42257073 1973-12-06 US3915057A 1975-10-28 BROXHOLM THOMAS M; ELMORE LESTER C
A gun of the kind in which liquid propellant is burned in the firing chamber to fire a projectile from the gun is constructed so that a number of gun modules can be combined in a modular gun. Each gun module is cam controlled, and a common cam is used to control each gun module in the modular gun. The cam can be a flexible cam having a belt configuration to permit the gun modules to be arranged in both circular groupings and in noncircular groupings, such as side by side. The modular gun includes fixed, non-rotating gun modules to eliminate the need for tangential velocity correction factors in the fire control and the need to accelerate the mass of the barrel assembly to operational speed. The individual gun module includes propellant injection mechanism for injecting propellant at high pressure when a non-hypergolic bi-propellant is used as the propellant. One or more hydraulic actuators are used to develop the high injection pressures and to operate other components of the gun, such as the bolt. The hydraulic actuators are also engaged with the cam to interlock the actuators and the controls for the actuators through the cam. A source of pressurized hydraulic fluid independent of the gun is used to power the actuators so that the weight and profile of the gun are kept to a minimum. The hydraulic system includes a compound spool control valve which operates in a dual mode to permit normal cyclic operation of the gun during firing and to maintain the gun in an open bolt condition during armed but non-firing operations. The hydraulic system includes a misfire detection mechanism and module shutdown valve which locks a misfired gun module in the closed bolt condition without the need to depressurize the hydraulic circuits of the other gun modules and without the need to include additional bypass circuits. The injection mechanism for injecting the bi-propellant includes two pistons which are yoked together and operated by a single actuator to inject the propellant into the firing chamber both in metered amounts and in a constant mix ratio. The pistons for injecting the bi-propellant include valves in the pistons, and the pistons are drawn through the fuel on retraction strokes of the pistons. The injection mechanism is retracted away from the firing chamber after the firing of a burst to isolate the propellant in the injection mechanism from the heat of the firing chamber. A rotary lock is mounted closely adjacent the bolt mechanism and engages a relieved area of the bolt in the locked position of the lock so that a quite small force on the lock will hold the bolt mechanism locked against high combustion chamber pressures tending to open the bolt.
86 Firing mechanism for a machinegun US3645165D 1970-10-20 US3645165A 1972-02-29 WOHLFORD WILLIAM P
A firing mechanism for a machinegun which comprises a bolt movable between a retracted and a battery position responsive to crank rotation and a firing pin slidingly disposed within the bolt. A firing pin spring is compressed by the crank-actuated drive pin during final displacement of the bolt to the battery position. Cam means rotates the bolt, when in battery position, around the firing pin into locked engagement with a barrel extension and thereby moves a recessed ramp in the firing pin into alignment with a sear fixed within the bolt bore for release of the firing pin when the locking engagement is completed.
