摘要： A pistol design is provided which makes it possible to make a small sized pistol for firing relatively large size cartridges, e.g., a .45 pistol. The pistol is manually cycled for reloading and is characterized by a barrel which must be moved forward to remove a spent case and backward to chamber a new cartridge, and novel means for (a) firing the weapon, (b) preventing accidental discharge of the weapon, and (c) preventing forward movement of the barrel when the trigger is pulled.

摘要： A pump action firearm includes a barrel and a chassis defining a magazine well for receiving a magazine. The magazine well extends longitudinally parallel to the barrel and contains a plurality of cartridges arranged in stacked relationship with each cartridge having its longitudinal axis extending substantially transversely to a longitudinal axis of the barrel. A pump member displaces the barrel forwardly and rearwardly. A carrier mechanism is linked to the pump member and, during pumping of the pump member, moves an end cartridge contained in the magazine from its stacked position to an operative position in alignment with the longitudinal axis of the barrel.

摘要： An explosive tool driving apparatus is provided having an improved extractor mounted upon its barrel holder, and the claw of which is meant to retain the case of a propulsive charge during opening of the apparatus. A groove for passage of the claw of the extractor is formed within the barrel of the apparatus. In the firing position, the claw is disposed in front of an abutment shoulder for the collar of the case, so as to provide an initial axial clearance, the extractor is freely movable in translation between two axial stops and, during opening, is moved forwardly by the means of collar of the case the improvement thereby avoiding the hard point during opening of the apparatus
