| 216 | Magazine holder and magazine suitable for right and left handed release | US59800 | 1987-06-09 | US4768301A | 1988-09-06 | Jorn Thomas |
| An important factor in firearms suitable for combat is the capability to permit replacing the magazine with one hand, that is, to permit the user to eject an emptied magazine by releasing it with the shooting hand and permitting it to drop out automatically, so that a full magazine can be inserted with the free hand. To accomplish this, a latch mechanism is arranged in a through hole formed transversely to the magazine opening and to the longitudinal axis of the barrel of the gun and includes two positive detent latches in a concave or arched portion, the detents being separated by a central groove. The detents have an outer arched or curved surface and on the inside provide straight walls for the groove, in this way a straight magazine can displace the latch axially. The magazine has two pairs of recesses in a rounded leading surface that are arranged so that the two detents seat in the recesses, thereby to accurately support the magazine in two dimensions. The latch mechanism is in one piece and is retained by a stop plate held by the hand grips of the gun and by a spring loaded stop mechanism that cooperates with a slot in the gun frame to permit movement of the latch assembly in one direction but to limit its travel in another direction. | ||||||

The hook (6) which is designed to engage in the slot (4) of the magazine (3) is fixed to a spring-loaded arm (8) located transversely in the body (1) of the weapon and can be moved either by means of a button (9) attached to one end of the said arm (8) or by means of a rocking lever (12) mounted at the other end of the arm (8). The hook (6) can thus be operated from both sides of the weapon. | ||||||
| 218 | Ambidextrous safety for guns | US228541 | 1981-01-26 | US4414769A | 1983-11-15 | Herman W. Mueschke |
| An ambidextrous safety system for guns wherein such guns are adapted for efficient use by right or left-handed users. The safety system is adapted particularly for handguns, such as the Colt 0.45 caliber semi-automatic handgun, for example, but it is also quite well adapted for other types of guns as well. Manually actuated safety devices are positioned on each side of the frame of the gun and are adapted to be moved between safe and firing position. A pair of pivot pins, connected to each of the safety devices, extend through apertures in the frame of the gun and are nonrotatably connected by means of a mechanical interlock. The mechanical interlock is located within a close fitting bore of the frame, thus providing a structural stability therefor. A sear pin also extends through registering apertures in the frame by one of the safety devices. The other safety device establishes a movable interlocked relationship with the opposite extremity of the sear pin, thus causing the other safety device to be maintained in movable assembly with the frame of the gun by the sear pin. The safety devices may include an extended manually engaging portion, allowing the user to readily manipulate the safety with the thumb of the gun supporting hand without material change in the position of the gun supporting hand. | ||||||
| 219 | Submachine gun having a pistol grip 360 degrees rotative about the barrel | US182096 | 1980-08-28 | US4327626A | 1982-05-04 | Sidney J. McQueen |
| The submachine gun also has a forward housing. The forward housing is installed over the forward bolt and barrel, and rotatably secured to the assembly collar, and to the barrel by a sling swivel and a muzzle nut. The forward housing has integrally made there with a pistol grip and trigger housing. The trigger housing contains the trigger mechanism and sear, said sear when the submachine gun is assembled engages selectively the plurality of ring grooves around the forward bolt. Externally attached and mounted to the front housing is a sight bridge. Thus assembled, the front housing with pistol grip and sight bridge may be fully rotated 360.degree. with respect to the stock, magazine, and ejector port while the sear continously engages the ring grooves of the front bolt, and the weapon is ready to fire and fully operable at any point of the 360.degree. rotation. | ||||||
| 220 | Magazine catch release for a hand firearm | US119407 | 1980-02-07 | US4326353A | 1982-04-27 | Walter Ludwig; Franziska Schmid, deceased |
| A hand firearm, such as an automatic pistol, has a butt or handle in which a magazine is mounted. The magazine is retained in position by a locking member which can be actuated from either side of the pistol by the hand of the user holding the firearm. The locking member is a spring-loaded lever which has a projection received in an opening in the wall of the magazine to lock the magazine in position. An actuating member extends on both sides of the firearm and is operatively connected with the locking lever so that actuation of the actuating element will pivot the lever to unlock the magazine. | ||||||
