    摘要： A firearm may include a receiver and a barrel coupled to the receiver having a chamber at a breech end thereof for receiving a round of ammunition, as well as a magazine that supplies rounds of ammunition to the chamber. The firearm may further include a bolt assembly movable about the receiver to direct the rounds of ammunition towards the chamber, and the firearm may also include a trigger plate assembly that may have a trigger, a hammer movable upon activation of the trigger, a carrier operable to direct the rounds of ammunition from the magazine towards the chamber, a feed latch operable to release the rounds of ammunition from the magazine to the carrier, and a latch release operable to engage the feed latch to facilitate the release of the rounds of ammunition.

    摘要： A novel firearm is lightweight, compact, and the method of manufacture is easy. A single or dual tubular magazine positioned below the barrel of a firearm includes the novel use of an inverted U-shaped stamped sheet metal receiver with a cavity for housing a loading and ejection port. The present invention advances the art of firearm manufacture by disclosing a tubular magazine and stamped sheet metal receiver that encloses the major parts of a firearm. The firearm is simple to manufacture, lightweight, approximately 25 to approximately 27 inches in length, and affords an ammunition capacity that is at least twice the capacity of a comparable firearm, such as the Remington® 870 shotgun.

    摘要： This automatic small arm mechanism provides the locking of the firing members by means of an independent member adapted to engage the intermediate lock member controlled automatically by the inertia block or manually. Thus, the main lock bolt will lock the intermediate lock member when the breech block is in its closed position, whereby the striker return spring may be as strong as desired and necessary since the return movement of the independent percussion member has no incidence whatsoever on the lock bolt position.

    摘要： The disclosure deals with an action disabling device in a firearm having among its conventional components a spring-closed breech bolt, a tube-type magazine, and a pivoted cartridge lifter. The disabling device is in the form of a spring-loaded latch part having with a fixed member of the action a floating pivot connection over a limited range, with the latch part being in its normal position at one end of its floating range in follower relation with the cartridge lifter such that on overtravel of the latter in lift direction for lack of a cartridge thereon, the part is turned into the closing path of the breech bolt and is on partial closure of the latter shifted by the same to the other end of its floating range at which it not only locks the breech bolt against complete closure but is itself also out of follower relation with the lifter and, hence, free for subsequent spring-retraction from locking relation with the breech bolt on mere manual backup of the latter from its partial closure.
