  • Patent number: 5744030
    Abstract: Embodiments of a fluid filtering assembly are shown and described, each embodiment including a valve head that routes fluid to and from a filter cartridge and that includes a valve system that automatically opens and closes when the filter cartridge is inserted and removed, respectively. The valve system preferably includes a generally-cylindrical piston with a hollow interior space, which receives a stem member. The stem member has a bottom-end seat or sealing member and has a central body shape that allows fluid to flow up through the piston interior space, either through or up around the stem member. Upon removal of the filter cartridge, the piston is biased to move down into an "off" position, to close both the inlet and outlet fluid passages. In this "off" position, the piston exterior surface blocks off radial fluid inlets and the piston interior surface seals with the stem bottom end seat to prevent fluid backflow out of the piston interior space.

  • Patent number: 4970820
    Abstract: An improved ammunition loading device designed for cartridges having radially extending rims, such as 0.22 calibre cartridges. The invention comprises a body having a spiral groove and a feed arrangement to drive the cartridges through the groove and into a magazine. A manual crank has an eccentric cam which operates two mechanisms alternately on each rotation of the crank. On half the rotation it operates a feed finger which inserts the next cartridge exiting the spiral groove into the magazine, and on the other half of that same rotation it advances the line of cartridges to present a fresh cartridge for insertion on the first half of the next rotation.

  • Patent number: 4965951
    Abstract: An improved magazine wherein cartridges are loaded therein in two nested helical rows. Improvements further include a spring loaded feed lip bar which permits rapid loading and unloading of the magazine; a rod inside the drive spring in the magazine which prevents kinking and other undesirable operation characteristics of the main drive spring and which also permits the main drive spring tension to be released only when the magazine is not mounted on the cooperating gun; and a folding winder which is part of the magazine's rear end clutch and winder assembly which speeds winding of the spring.

  • Patent number: 4879829
    Abstract: A loader particularly adapted for a cylindrical helical path feed ammunition magazine, the loader being able to accept cartridges as provided by the cartridge manufacturer in trays, whole trays at a time. The loader is made up of two hinged arms, with a platform on one of the arms to accept the tray of cartridges. After the tray is removed, the cartridges remain in the same array as they were in when in the tray, and then the arms are closed to create a dense mass of the large number of cartridges. The loader is then positioned vertically, a magazine inserted, and the cartridges quickly loaded into the magazine by turning a crank.

  • Patent number: 4766800
    Abstract: An improved gun/magazine system which is top loading and wherein the magazine is of generally cylindrical configuration. A spiral drive of the cartridges through the magazine into the top loading receiver of the gun is provided. The magazine includes a spring/winder having a silent clutch which permits tensioning of the drive spring at any time and even immediately before use, and which has a release means in order to permit relaxing of the spring in the event the unprecedented large capacity of cartridges is not entirely expended from the magazine. The cylindrical shaped magazine is mounted above, parallel to, and closely adjacent to the axis of the gun.

  • Patent number: 4676137
    Abstract: The disclosure relates to firearms, especially recoil or gas operated firearms, having a receiver for cartridges, and having a magazine for containing a plurality of cartridges. The magazine can be disposed above and substantially parallel with respect to the barrel. The magazine includes a housing with a helically disposed member providing a helical passageway for the cartridges. The cartridges are supported on a cartridge carrier located in the housing, which can be rotated by a torque spring. The cartridges are unloaded from the magazine by a feed lip insert providing communication with the receiver of the firearm.
