Abstract: A chain drive of a V-engine with overhead camshafts includes chains which are driven by a crankshaft. In each case the overhead cam shafts are driven by a separate chain. Tensioner blades swivellably assigned to a respective slack run of the chains are acted upon by hydraulic chain tensioners of the same type of construction. The chain tensioners are arranged in an accessible manner on the exterior side on the V-engine and interact with sloped contact ramps on the tensioner blades. The chain tensioners of the same construction are arranged transversely to one another on the V-engine and are configured for a reliable venting in each installed position by including two mutually independently operating leakage devices.

Abstract: A housing for use with a firearm is provided. The housing includes a first housing section sized for receiving a barrel, and a second housing section coupled proximally to the first housing section for receiving a breechblock mechanism. The first housing section has a top external surface. The second housing section has a forward portion which is offset from the first housing section and which includes a forward surface defining an opening sized for receiving a connecting element operatively connecting a lever disposed adjacent the top external surface outside the first housing section and the breechblock within the second housing section. The connecting element moves perpendicularly to the opening and not, as in prior art housings, along it, so that the previously required longitudinal slit, which severely weakened the structure of prior art housings, is avoided.

Abstract: An automatic combination rifle with a large caliber automatic rifle system and a normal caliber automatic rifle system that include respective triggering arrangements which are connected with a single, movable trigger lever with the use of an activated change-over mechanism. Each triggering arrangement comprises a movable release mechanism to control the respective trigger function. The change-over mechanism establishes a selective connection with one of the release mechanisms for cooperative movement with the trigger lever.

Abstract: The invention relates to a firing pin and hammer assembly for a fire arm, especially a self-loading fire arm with a closed breech of a submachine gun, the assembly comprising a firing pin capable of being moved from a rest position at which its end is positioned in the travel path of a hammer, to a priming position; a firing pin spring for moving the firing pin into its rest position; a catch (14) capable of being moved by a catch spring engaging the firing pin while the firing pin is in its rest position, and holding the same; and a release assembly cooperating with the hammer and releasing the catch from engagement with the firing pin when the hammer approaches the end of its travel path. The object is to prevent any movement of the firing pin unless the hammer is released. According to the invention, the release assembly is permanently coupled to the hammer for preventing an untimely and excessively forceful operation of the release assembly.

Abstract: A repeating shot gun, in particular a automatic shot gun, is provided with at least one barrel (29) which is rigidly attached to a plastic housing (1) when the gun is assembled, the shot gun having a coupling (3) formed either from a metal or from a material having properties similar to those of metals with respect to deformation and strength and having a barrel receiver (5) which is rigidly positioned in the housing (1), such that the barrel receiver (5) substantially coaxially surrounds the rear portion of the barrel (29) and the barrel (29) is in close-fitting engagement with the barrel receiver (5).

Abstract: A rifle construction with a swing-type barrel assembly is adapted for firing both conventional cartridges and non-conventional cartridges with a longitudinally extending barrel assembly having a first barrel and a second barrel mounted in opposed relation. A breech block interposed between the barrels is adapted for sliding cooperative movement with the first or second barrels in order to expel desired cartridges depending on the mode of operation. A housing is adapted to receive the barrel assembly in first and second firing positions.

Abstract: A small arm having a barrel (11) with at least one transverse bore (14) and a detachable silencer (62) including an expansion chamber (58) communicating with the transverse bore, comprising selectively operable closure means (34) arranged in the path of the combustion gases between the interior of the barrel and the expansion chamber is characterized by an arrangement in which the closure means (34) is prevented from opening or remaining in the open position when the silencer (62) is not in place. Thus, any risk of injury to the shooter is excluded.

Abstract: The invention relates to a hand-held firearm comprising a muzzle silencer (9) and a barrel (11) which is provided with transverse bores and is surrounded by an expansion area (15) into which the transverse bores extend. The transverse bores (14) enable the muzzle velocity of the bullets to be less than Mach 1, in spite of the use of conventional ammunition, and there is consequently no supersonic boom of the bullet. To selectively eliminate the reduction in firing energy involved therein and be able to shoot with maximum firing force, the transverse bores (14) are selectively closable by a locking device (16) which is preferably in the form of a sleeve (16) which surrounds the barrel (11) and is mounted for rotation thereon and is furthermore provided with an actuating member (21) for setting the open or closed position.
