| 134 | Rotatable breech mechanism | US09737436 | 2000-12-13 | US06481135B2 | 2002-11-19 | Meinrad Zeh; Sergej Popikow |
| 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. In one rotated position of the bolt, a rear end of the pin is received in a forwardly open recess of a shoulder surface on the bolt handle, and upon a rotation of the bolt out of the one position the rear end of the pin slides out of the recess onto the shoulder surface, and the chamber housing with the bolt is movable to a rearward position. | ||||||
| 135 | Arrangement for opening the dust flap of a firearm | US09916911 | 2001-07-27 | US20020073592A1 | 2002-06-20 | Johannes Murello; Helmut Weldle |
| An apparatus is provided for use in a firearm having a housing defining a first ejection opening and a second ejection opening. The apparatus includes first and second dust flaps mounted adjacent the first ejection opening for movement between an opened position and a closed position. The apparatus also includes a bolt assembly adapted to be selectively mounted in a first assembly position and a second assembly position for longitudinal movement within the housing. When the bolt assembly is in the first assembly position, a longitudinal movement of the bolt assembly moves the first dust flap to the opened position and, when the bolt assembly is in the second assembly position, the longitudinal movement of the bolt assembly moves the second dust flap to the opened position. | ||||||

| A slide action pistol including a frame; a barrel supported on said frame and having a bore on an axis of the barrel; a handgrip portion of the frame provided with a cavity therein for receiving a magazine; a firing assembly including a trigger, hammer and firing pin arranged in operative relationship; and, a slide having one end engaged with the barrel and an opposite end pivotally connected to the handgrip portion, the slide arranged to pivot upwardly and rearwardly when the pistol is fired. | ||||||
| 137 | Rapid fire mechanism for firearms | US09288743 | 1999-04-08 | US06212991B1 | 2001-04-10 | Taylor Frazier, III |
| The invention provides an apparatus for reducing recoil on a firearm or gun and to increase rate of firing. The invention uses a dual mass system to dynamically balance the gun wherein some of the energy of firing is absorbed within springs and thereby reduces the recoil force imparted to the gun user. The apparatus also comprises an ejector mechanism for ejecting a spent round and reloading a new round from the gun magazine with increased speed over conventional designs. The apparatus is applicable to automatic and semiautomatic handguns as well as rifles and machine guns. | ||||||
| 138 | Firing pin safety catch mechanism | US358189 | 1999-07-21 | US6145234A | 2000-11-14 | Norbert Fluhr |
| A firing pin safety catch mechanism for use with a firearm is disclosed. The safety catch mechanism includes a one-piece leaf spring comprising a spring arm, a safety catch and a beveled release part. The safety catch has a first position wherein the safety catch engages a catch surface of a firing pin to secure the firing pin in a rest position and a second position wherein the safety catch disengages the catch surface to release the firing pin for movement out of the rest position. The beveled release part is disposed adjacent the proximal end of the spring arm. It includes a camming surface disposed within the motion path of a hammer when the safety catch is in the first position such that, as the hammer moves to strike the firing pin, the hammer cams the camming surface of the beveled release part against the force of the spring arm to move the safety catch from the first position to the second position, and the hammer then strikes the proximal end of the firing pin to displace the firing pin from the rest position. | ||||||
| 139 | Magazine loaded pump action shotgun | US105953 | 1998-06-26 | US6032395A | 2000-03-07 | James K Bentley; Willard H Crawford |
| A pump action shotgun that has been designed to accept a shotgun shell magazine that can be quickly and easily attached or removed. An aperture is formed in the bottom surface of the receiver forwardly of a trigger housing assembly aperture. The top end of the magazine has a feed lip assembly that restricts the upward travel of the shotgun shells prior to their being transported to the rear end of the gun barrel by the bolt assembly as it travels forwardly. A spring loaded tang extends downwardly from the front bottom surface of the bolt assembly and travels through the feed lip assembly where it engages the rear end of the upper most shotgun shells and carries it forwardly to the rear end of the gun barrel. A bolt slide that is detachably secured to the bottom surface of the bolt assembly has a concave bottom surface that allows it to travel forwardly and rearwardly over the top of the feed lip assembly of the shotgun shell magazine. A unique winged ramp assembly prevents the shotgun shells from jamming the shotgun as they travel into the rear end of the gun barrel. | ||||||
| 140 | Shoulder-launched multiple-purpose assault weapon | US788569 | 1997-01-24 | US5835978A | 1998-11-10 | Michael M. Canaday; Fred W. Watson, Jr. |
| A shoulder-launched multiple-purpose assault weapon having a modified spotter rifle with a top-mounted rocket launcher tube is provided. The spotter rifle forms the base structure of the weapon and all weapon controls are located on the spotter rifle. The spotter rifle has several dual-function mechanisms which perform the combined functions of assembly and safing, bolt-locking back and cartridge ejecting, simultaneous adjustment of both open and optical sights, firing, selectively, of both the spotter round and the rocket round. The combination of these dual-firing mechanisms provides a lighter weight, better-balanced and smaller weapon. The reduction in parts count improves reliability and lowers cost. Other improved features include an adjustable spotter rifle barrel used to match the boresight of the rocket tube and an improved locking mechanism. A dual function trigger assembly operated two sears from a single trigger. The primary sear operates a rotating type hammer while the secondary sear operates a plunger-type hammer. The hammers fire, respectively, the spotter rifle and the rocket tube as selected by the gunner. | ||||||
