Abstract: A reciprocally-cycled, externally-powered weapon may include a rotative driver connected via a crank and connecting rod to the operating group of the weapon. The connecting rod may be connected to a pinion that meshes with a translating rack and a stationary rack. The translating rack may be connected to the operating group, and the stationary rack may be fixed to the receiver of the weapon. The energy needed to fire the weapon may be supplied by an energy generator. The minimum amount of energy supplied by the energy generator may be independent of the speed of translation of the operating group and may be sufficient to reliably result in cartridge ignition, thereby providing an infinitely adjustable firing rate.

Abstract: An attachment for a semi-automatic firearm converts the firearm into a weapon of rapid fire. The attachment includes a crank driving a cam assembly in which the cam is mounted for limited relative movement to the crank. A spring in the attachment acts to bias the cam assembly relative to a follower to a safe non-firing position. The follower is acted on by the cam assembly to manipulate a linkage for pulling a trigger of the firearm in response to rotation of the crank. The follower and cam are designed to minimize the time of maximum movement of the follower thereby maximizing the time allowing the firearm to reset. In one embodiment, a timing mechanism is provided to insure that the bolt of the firearm is in its chambered position before the cam is allowed to actuate the firearm trigger.

Three different firing mechanisms are provided, the first employing a firing pin and shock tubing, the second employing a metal sphere and shock tubing, and the third employing a firing piston and a source of compressed air.

Abstract: A trigger extension device attached to a trigger of a paint ball marker gun used in the sport of paint ball marking. A trigger extension bar attached to the trigger at a transverse orientation at a distance from the trigger provides a grip for a user to fan the trigger at a high rate of speed at a position external to the trigger. The trigger extension bar is connected to the trigger in transverse orientation to the left and right side walls of the trigger. The trigger extension bar is linear and is perpendicular to the left and right trigger walls. The distal end of the trigger extension bar can optionally include an angled portion. The trigger extension bar can extend from either the left or right side of the marker gun trigger or can extend from both sides of the marker gun trigger. The trigger extension bar can be connected to the trigger by an extension screw that is threaded through a threaded hole in the trigger and also mounted to an axial threaded bore in the trigger extension bar.

Abstract: This disclosure is directed to a trigger operating mechanism for sighting in rifles which could be utilized by either a right-handed or left-handed user. A preferred trigger operating mechanism comprises a pair of plates which are clampable against opposed sides of the trigger guard of the rifle. A shaft traverses one of the plates, and the inner end of the shaft mounts a trigger displacing cam adjacent the trigger between the pair of plates. A manually operable knob is secured to the outer end of the shaft. Rotation of the knob will effect a gradual rearward displacement of the trigger to its firing position, thus eliminating any tendency of the user of the rifle to jerk the trigger and disturb the line of sight for the particular firing. Alternative embodiments may include a lock such that a key is required to operate the mechanism, a single mounting plate rather than a pair of mounting plates, or a snap-in mounting body that mates with the interior surface of the trigger guard.

Abstract: The improved gun has a rapid fire trigger assembly. The gun has a main body and a trigger connected thereto and depending therefrom, with the lower portion of the trigger biased into a forward, non-firing position. The improved rapid fire trigger assembly includes a housing having spaced sidewalls and interconnecting front and rear sides and is adapted to be connected to the gun in front of the trigger. A generally circular elongated tube passes transversely through the housing sidewalls and into the central space in the housing. The tube is rotatable relative to the housing and has a central portion within the housing, which central portion has a number of spaced radiating spokes extending outwardly therefrom. The tube also has opposite end portions extending lateral of the housing sidewalls, one of which end portions has a crank with a trigger finger-receiving space therein. The crank is adjacent the external surface of the sidewall.
