  • Patent number: 5502913
    Abstract: A cartridge magazine for use with a firearm includes a housing arranged to enclose a plurality of cartridges. The housing has an opened end and a mouth for permitting cartridges to be loaded therein and dispensed therefrom. A follower is movably positioned within the housing and biased toward the mouth. At least one movably mounted tongue and an opposing member are associated with the mouth. The movably mounted tongue is constructed and arranged to move between a first normally biased cartridge retaining position wherein a forward-most cartridge is retained in the mouth by the tongue and the opposing member and a second cartridge loading position wherein the movably mounted tongue is moved linearly away from the mouth as a new cartridge is inserted thereinto. The tongue thereafter returns to the first cartridge retaining position.

  • Patent number: 5143266
    Abstract: The harness comprises a carrying strap and a gripper. The carrying strap is formed from a soft material. Another strap formed from a stronger, less resilient fabric is attached to the soft strap at uniformly spaced intervals and in such a way that the second strap forms loops at its points of attachment to the soft strap. With the arrangement, the soft strap can only stretch until the loops become taut. Thereafter, the stronger second strap carries the load and this prevents the soft strap from tearing when heavy loads are carried. The gripper is formed from a resilient material and comprises a first plate and a second plate which are connected together by an arcuate web. One of the plates of the gripper has a flat body contacting surface and a loop is positioned in the arcuate web between the first and second plates for connection to a device to be carried. A plurality of pins are formed on at least one plate of the gripper.
