  • Publication number: 20160046536
    Abstract: Electrically ignitable caseless propellant charge in the form of a caseless propellant tablet (5), characterised in that it is obtainable by mixing together of at least one current-conductive material in dissolved or dispersed form or powder form and graphite in powder form, together with nitrocellulose, with or without addition of further additives, and subsequent compaction to form a propellant tablet, the production and use thereof, and related subject matter of the invention. Uses include: use of the propellant charge in a bolt-driving tool for installing bolts, as an explosive charge in a warning shot device, as a gas-generating element in airbags, for driving cutting devices, for driving pressing devices (for example for squeezing tong-like elements together) or as a propellant charge in small calibre rifles for sporting purposes, or for captive bolt devices for animal slaughtering.

  • Patent number: 7096620
    Abstract: The invention relates to a device for mounting a telescopic sight onto a weapon. The device is equipped with two mounting feet, which are positioned at a distance from one another and provided with mounting elements for engaging in corresponding receiving openings on the weapon. The aim of the invention is to enable the sight to be positioned accurately without the need for a complex adjustment and fitting process. To achieve this, the mounting elements are configured by clamping bolts, which comprise laterally protruding lugs, are contained in the corresponding mounting feet and can be rotated through a release and locking position. The lugs can be inserted into recesses between inward-facing projecting shoulders of the receiving openings in the release position of the clamping bolts and engage with the underside of the projecting shoulders in the locked position of the bolts.

  • Patent number: 6502344
    Abstract: In order to secure firearms against unauthorized use, an insert is inserted into a portion of the barrel, which insert has an expandable sleeve. A first expanding device is releasably inserted into one end of the expandable sleeve to thus press lockingly against the inside wall of the barrel. A second expanding device is inserted into the other end of the expandable sleeve. When an axial pressure is applied to the second expanding device, the expandable sleeve engages the inside wall of the barrel. The one end of the expandable sleeve is covered with a protective plate which can only be destroyed by spark erosion when the expandable sleeve is removed from the barrel.

  • Patent number: 6481135
    Abstract: A rotatable breech mechanism includes a bolt rotatably supported in a chamber housing by a bolt handle, and which in one rotated position thereof is locked to a barrel chamber sleeve and in a further rotated position thereof is unlocked from the sleeve. A spring-loaded extractor is arranged at a front end of the bolt. The extractor, in one rotated position of the bolt, grips an edge of a bottom of a sleeve of a cartridge inserted into a cartridge chamber, whereby upon a rotation of the bolt from the one position into a further position the chamber housing with the bolt automatically carries out a movement away from the cartridge chamber during which the extractor releases the cartridge from the cartridge chamber. The chamber housing supports an axially movable pin which is supported at its front end on the barrel chamber sleeve.

  • Patent number: 5363581
    Abstract: The firing mechanism for a rifle comprises a trigger (2) fixed to a trigger blade (4) and a two-armed firing lever (5) pivoting in the breech housing, the first lever arm (5a) being directly or indirectly connected to a firing sear (7) which holds a retainer (10) on the end (11a) of the firing pin in the cocked position, whereby the firing spring exerts a turning moment on the firing lever (5) in the cocked position, through the firing pin, the retainer (10) and the firing sear (7). A link (13) is hinged at one end to the trigger blade (4) and at the other end to the second lever arm (5b) by means of two hinge axes (14, 15) running parallel to the trigger axis (3). The first hinge axis (14) at the trigger blade is so arranged relative to the second hinge axis (15) at the second lever arm (5b) that, in the cocked position (FIGS.

  • Patent number: 5353539
    Abstract: The mounting device for a telescopic sight on a rifle comprises a mounting bridge (5) which carries a holder (6) for the telescopic sight and on one side at each of the front and the rear ends a fixed jaw (10) and on the opposite side two movable jaws (14) movable transverse to the mounting bridge (5). The receiver (2) of the barrel comprises two blind bores (3) running substantially radially relative to the barrel axis and offset from one another in the direction of the barrel axis (A) . Opposite each blind bore (3), on the other side of the barrel, there is provided an approximately half-moon shaped notch (4), the bottom surface (4a) of which running in the barrel direction forms a clamping surface for a movable jaw (13, 14). The two fixed jaws (10)each comprise a cylindrical retaining pin (11) which fits in one of the blind bores (3). Each movable jaw consists of a pivoting lever (13) with a locking nose (14).
