  • Patent number: 5953845
    Abstract: The quick-loading device proposed has a cartridge holder which holds cartridges in such a way that they can be inserted simultaneously into the chambers of the revolving cylinder and released from the holder. The cartridge holder can be adjusted so that the positions of the cartridges in it can be changed, preferably in synchronized fashion, and thus adapted to the different types of revolver. The quick-loading device proposed can be secured to prevent the cartridges in it from being released.

  • Patent number: 5930930
    Abstract: A gun locking security device is provided including a combination assembly with a plurality of dials having a central extent with a plurality of numbers formed on a periphery thereof. The dials are rotatably coupled in coaxial relationship within an interconnection of a barrel portion and a handle portion of a gun. A safety mechanism is provided for allowing the firing of the gun upon the actuation thereof. An actuator assembly is connected between the combination assembly and the safety mechanism for actuating the safety mechanism only upon the rotation of the dials such that a predetermined combination of numbers is selected.

  • Patent number: 5915934
    Abstract: A muzzleloading rifle has a bolt with a laterally extending handle. The bolt is operationally connected to the cocking piece of the firearm by means of engaged cam surfaces of the bolt and the cocking piece which will permit the rifle to be cocked only by moving the bolt handle in an upwardly and rotational motion without any longitudinal movement of the bolt towards the cocking piece. After the firearm has been loaded by means of depositing a disc element with a primer element in the center bore thereof in the breech opening of the firearm, the firearm is placed in a firing condition by reversing rotational motion of the bolt handle. The disc element has a center bore which is adapted to receive a conventional nipple and a percussion cap, or in lieu thereof, and preferably, a shot gun primer. The latter is preferred in that it provides a hotter and more intense ignition of the gun powder in the muzzleloading rifle art.

  • Patent number: 5913669
    Abstract: A system and mount for releasably coupling an infrared aiming light beneath he barrel of a shotgun, including a gun barrel and an extended tubular magazine. The mount includes four clampable opposing mount surfaces, where two of the surfaces approximates a curvature of the firearm barrel and two that approximates a curvature of the extended tubular magazine. A rail mating surface and draw screw releasably couples a rail, integral with an infrared aiming light, to and below the mount surfaces. The system includes optional activation of the aiming light using a tape switch located on the hand grip of the shotgun.

  • Patent number: 5911568
    Abstract: The present invention relates to an underwater weapon having a barrel with n opening through which a projectile is discharged. The weapon further has an apparatus for pressurizing the interior of the barrel to a pressure greater than the ambient pressure to keep water from entering the gun barrel at any point around the circumference of the muzzle opening. The pressurizing apparatus includes a source of gas, a pressure regulator for adjusting the flow of the gas and the pressure within the barrel, and a distribution network for distributing the gas near the muzzle opening and at an end of the barrel remote from the muzzle opening.

  • Patent number: 5907920
    Abstract: An ignition assembly for a muzzle loading firearm. The ignition assembly includes a conventional breech plug and a modified percussion nipple having a rearward end for receiving a percussion cap and a forward end which extends into the nipple bore of the breech plug. The forward end of the nipple has a reduced diameter so that there is an annular space between the outer surface at the forward end of nipple and the inner surface which defines the nipple bore of the breech plug. The nipple has a rearward fire channel which extends forwardly from its rearward opening and a forward fire channel which extends from the forward end of the rearward fire channel to its forward opening at the powder well of the breech plug. A pair of side fire channels extend from the rearward fire channel to the annular space between the forward end of the nipple and an annular inner wall which defines the nipple bore of the breech plug to enable this annular space to function as an axillary fire channel leading to the powder well.

  • Patent number: 5887352
    Abstract: A gun sight system for accurately directing a bullet of a firearm towards a target, comprising a front sight and a rear sight each having a transparent medium with a geometric shape inscribed upon the transparent medium. By looking through the rear sight towards the front sight and aligning the geometric shapes in a pre-determined manner with the target seen in the background through the transparent mediums, an accurate contact of the bullet with the target is guaranteed upon firing the firearm.

  • Patent number: 5878504
    Abstract: A rifle scope vertical alignment apparatus includes first and second plates, each with a bottom surface shaped as an inverted V. A vertically oriented elongate slot is formed in one of the first and second plates and a receiving channel is formed in one of the first and second plates to slidably engage the other of the first and second plates. A level is positioned on one of the first and second plates such that it is visible from a rear surface of the apparatus. A threaded screw extends through the slot and into a threaded bore on the other of the first and second plates so that the plates can be held in a selected position relative to each other with the inverted V bottom surfaces aligned. The alignment method involves positioning the inverted bottom V of the first plate of the alignment apparatus atop the rifle barrel just in front of the objective end of the scope, placing the inverted V bottom surface of the second plate atop the scope barrel and then tightening the threaded screw.

  • Patent number: 5877448
    Abstract: A reusable gas-powered war game land mine has at least one launch tube with ne or more projectile(s) loaded therein. A compressed gas reservoir and rupturing device are provided with the rupturing device being movable in relationship to the seal of the compressed gas reservoir. A triggering mechanism is coupled to the rupturing device to move the rupturing device so that it impacts the seal when the triggering mechanism is activated. The rupturing device can define a channel through which the compressed gas is directed to the breech end of the launch tube(s) when the seal is broken. As a result, the compressed gas enters the breech end of the launch tube(s) to propel the projectile(s) therefrom.
