Abstract: A Rapid Fire Trigger Activator and accessory gun stock used to convert any semi-automatic carbine, rifle, or shot gun to nearly the firing capability of an automatic weapon which includes, a main side plate, having a pivot pin; a slide tube; a fore end hand grip; a slotted cam plate; a transfer bar; a swing out safety block; a trigger activator having a spring load plunger pin; and a nylon bearing block. When the fore end hand grip is pumped back and forth it will cause the transfer bar to pivot about the pivot pin which in turn will cause the trigger activator to be displaced towards the weapons trigger by the swing out safety block due to the up and down displacement of a transfer bar slot pin as it follows the cam slot. The trigger of the weapon is always fully accessible and functional whether or not the safety block is in place or not.

Abstract: A fire control mechanism (4) for an automatic cannon comprises a trigger control member (6), which engages the trigger (3) of the cannon structure (2) and is operable by an actuator (5) to move from an inoperative position against a restoring force to an operative position for operating the trigger. To ensure that the cannon has a capability not only for sustained fire but also for a reliable firing of single shots operative connection between the actuactor (5) and the trigger control member (6) is provided by a clutch (16). An end stop (16) is provided, which is selectively movable to and from an inoperative position and only in said operative position is arranged to disengage said clutch when the actuator has performed the movement which is required to move the trigger control member from its inoperative position to its operative position.

Abstract: A rifle or similar weapon having a mechanical trigger is provided with a mechanism to discharge it by remote command without interfering with the normal trigger action of the weapon. The weapon operator remains in control of his weapon and is able to discharge it at will. A push-type solenoid is arranged to move the trigger in response to an electrical fire command signal from a source external to the weapon and firing circuit is provided to accept the command signal and activate the solenoid. The firing circuit is arranged to prevent discharge of the weapon by external signal except when it is in an aimed, fire-ready position as signaled by the weapon operator.

Abstract: The gun is semi-automatic and preferably is an M-16/AR-15. It includes a firing trigger, frame and trigger guard, as well as a multiple firing gun trigger extension assembly. The assembly includes an elongated trigger guard bar incorporated into the trigger guard below the gun trigger, and a trigger-actuating component rotatably secured to the guard bar and including a supplemental trigger below the guard bar and a number of spaced trigger-actuating fingers disposed in an arc above the supplemental trigger. The fingers during their rotation can contact the gun trigger directly to affect sequential firing of the gun or can sequentially strike an interposed trip lever which is rotatably secured to the guard bar, the trip lever thereupon sequentially striking the gun trigger to effect the firing. Suitable springs and the like can return the trip lever and other parts to the resting position. A second supplemental trigger can be connected above the fingers to effect a second series of sequential firing.

Abstract: An attachment or accessory, for semi-automatic firearm, comprising a housing releasably attached to the trigger guard of the firearm, a rotor member rotatably supported in the housing and having cams or lobes adapted to repeatedly actuate the firearm trigger through the intermediary of a rocker member actuated by the rotor cams when the rotor member is rotated. A lever-supported crank and a meshing pinion arrangement rotates the rotor through a one-way clutch coupling when the lever is displaced in one direction, the one-way clutch coupling disconnecting the rotor from the pinion when the lever is displaced in an opposite direction to a return position.

Abstract: A trigger device for an automatic firearm having a linear action breech block. The device includes a catch lever movable to arrest movement of the breech block and a specially constructed kinematic chain which prevents the occurrence of an ambiguous intermediate position of the catch lever which could allow the breech block to damage the catch lever and/or linkage elements connected thereto.

Abstract: A timing attachment is described, for use in conjunction with a trigger and firing mechanism of a firearm, to enable adjustment of the timing action of such firearm. The attachment includes a saddle section and a ramp section. The saddle section is configured so as to enable the timing attachment to be seated on the trigger. The ramp section is connected to the saddle section, preferably integrally, and is operable to abut a cross piece in the form of a stationary frame member in the firearm. Securing means are also provided in the timing attachment, preferably in the saddle section, enabling the timing attachment to be adjustably secured to the trigger. This allows the ramp section to variably abut the cross piece and so cause adjustment of the timing action.

Abstract: An attachment for a semiautomatic weapon constructed with a trigger and trigger guard is disclosed, and the preferred embodiment incorporates a clamp means adapted to be releasably attached to the trigger guard, a rotor means pivotally supported by said clamp means for rotation about an axis to drive a movable striker means in a reciprocating fashion against the trigger enclosed by the trigger guard. A laterally extending handle equipped with a knob at the outer end is rotatable to turn a shaft which, in turn, rotates the rotor.

Abstract: A weapon system in which a plurality of guns, each capable of being aimed at a different selected one of a corresponding plurality of targets, are fired only when all are on target, whereby the plurality of guns will be fired simultaneously at the plurality of targets.

Abstract: An auxiliary firing mechanism (26) used to actuate a tripper for a gun trigger includes a remote actuator (28) connected to the tripper by an elongated connector such as a cable (30) that is moved by the cooperable action of a control member (68) and a rotatably and axially movable actuator member (74) of the actuator. Camming surfaces (90,92) of the control member and the actuator member of the actuator move the control member from a first position to a second position against a spring bias (76) thereof in order to actuate the tripper and thereby trip the gun trigger whereupon the camming surface (92) of the actuator member moves out of engagement with the camming surface (90) of the control member in order to allow the control member to be moved back to the first position by its spring bias. Axial and rotational movement of the actuator member then again engages the camming surfaces of the control and actuator members in preparation for another actuation of the tripper.
