Abstract: A shell feeding system for a top loading shotgun in one embodiment includes a barrel, receiver, and a magazine. The magazine includes a cavity configured to receive a plurality of ammunition shells in stacked end-to-end relationship. The magazine is positioned above the barrel and extends forward from the receiver. Shell guide grooves are formed by internal surfaces in the receiver which engage and guide each shell in a feed pathway towards the lower part of the receiver for chambering. A portion of the guide grooves may be arcuately shaped to rotate and reposition the shell for loading by the bolt into the chamber. In one embodiment, the receiver and magazine may be formed as a unitary integral structure formed as either a single piece or in half sections coupled together.

Abstract: An ammunition compartment is located in the grip of a firearm's handle. The handle has a hinged door that opens to the compartment. The ammunition is mounted on a strip clip which slides into grooves in the inner walls of the compartment. The strip clip has a tab which extends outside the compartment when the door is open so that the ammunition can be quickly pulled from the compartment to load the firearm.

Abstract: An improved single-shot rifle is shown having a rifle barrel secured to a receiver and having a lever-activated falling block action. The action includes a hammer and trigger each pivotally connected to the lever. A breechblock is moveable downwardly within a breechblock mortise provided on a rear surface of the receiver from a safety position wherein a firing pin carried thereby is aligned with a recess in the hammer and a firing position in which the firing pin is aligned with a striking surface of the hammer so that pulling the trigger releases the hammer and allows the striking surface thereof to strike the firing pin and fire the rifle.

Abstract: Disclosed is a repeating firearm having a vertically slidable block mounted behind the barrel. The upper portion of the block carries a firing pin, and one or more cartridge holding chambers are provided in the lower portion. A cartridge ejector is mounted at the rear of the barrel. The block is slidable between a lower position permitting operation of the ejector, an intermediate position aligning the firing pin with the barrel, and one or more upper positions aligning said cartridge holding chambers with the barrel for transferring cartridges from the chambers to the barrel for firing. In one embodiment a tubular magazine is provided beneath the barrel for holding additional cartridges end-to-end and means are provided for transferring cartridges from the magazine to a cartridge holding chamber in the block, for ultimate transfer therefrom into the barrel.

Abstract: Integral single or double body structures of a line guide frame formed by application of stamping to a metallic plate combined with a seat tube made of an elastic material such as synthetic resins assures successful elimination of trouble conventionally caused by brazing of junctions, damage on the rod surface and a breakage caused by degradation of the synthetic resinous parts.
