Firearm

A firing rate regulating mechanism for an automatic firearm is provided. The firearm, typically, operates according to the closed bolt principle in which a moving bolt carrier carries a bolt that locks each cartridge in the chamber prior to firing. A moving firing pin and a hammer are provided to strike the cartridge's primer subsequent to locking of the bolt. A time delay unit is provided and is movable between a compressed position and an expanded position. Movement to the compressed position occurs at a first, relatively rapid rate while movement to the expanded position occurs at a second slower rate. A linkage is provided that compresses the time delay unit as the bolt carrier moves routinely and the hammer is retained against forward movement to strike the firing pin until the time delay unit has moved back into an expanded position. According to one embodiment, the time delay unit can be interconnected with an automatic sear that normally engages the hammer. The time delay unit, and its linkages, are interposed between the automatic sear and the bolt carrier, while the automatic sear is taken out of direct interconnection with the bolt carrier.

Firing rate regulating mechanism

A firearm with a firing mechanism having a hammer, a trigger, a semi-automatic disconnector, an automatic sear, and an electro-mechanical movement mechanism for moving the automatic sear. The trigger and semi-automatic disconnector can be used to fire the firearm in a semi-automatic firing mode. The electro-mechanical movement mechanism can control release of the hammer by the automatic sear, but only after a first firing of the firearm by release of the hammer from a mechanical interlock with the trigger. The electro-mechanical movement mechanism has an actuator attached to a piezoelectric member. The piezoelectric member moves the actuator to move the automatic sear between a hammer holding position and a hammer release position.

Combined mechanical and Electro-mechanical firing mechanism for a firearm

A fire rate control mechanism which allows an open bolt or closed bolt S.M.G. or L.M.G. to be, upon firing, momentarily arrested in a cocked condition and then to be released to fire another round after a predetermined and preset lapse of time.
