| 121 | Pistol | US791056 | 1991-11-12 | US5179233A | 1993-01-12 | Alexander B. du Plessis |
| A pistol has a trigger 18 pivotal between a forward rest and a rearward depressed condition. It has a firing pin assembly 60 incorporating a firing pin 68 and a transverse nose 74. The assembly 60 is translational parallel to a barrel. When in rearward, cocked condition as illustrated, a firing pin 76 is compressed to propel it forward when released. A transmission member 50 is pivoted at a fore end to the trigger 18 and is guided for displacement along a cocking path. The nose 74 extends into the cocking path. Depression of the trigger displaces the member 50 along the cocking path. The member 50 abuts the nose 74 and cocks the assembly 60. The invention provides a pivot member 64 which hooks onto the member 50 and deflects it out of its cocking path to release the nose when the assembly 60 is cocked. A resetting formation 96 is provided on a movable slide 14 to reverse pivot the pivot member 64 to disengage it from the member 50 when a cartridge has been fired. | ||||||
| 122 | Slide safety stop for pistols and other small arms | US673605 | 1991-03-18 | US5129172A | 1992-07-14 | Edward J. Brennan |
| A safety stop for small arms having a slide, which keeps a catastrophic fure of the slide from causing shooter injury is disclosed. An improvement in the ejector and slide permit them to function together as a safety stop to prevent a broken slide from continuing off the back of the receiver in the event of catastrophic failure of the slide. A widened section on the ejector is accommodated in the ejector slot of the slide during normal firing of the weapon. An internal shoulder fixed relative to the slide and projecting into the ejector slot near the front of the slot is provided. Upon catastrophic slide failure during firing, the rear portion of the slide travels beyond its normally most rearward position and the internal shoulder engages the widened section of the ejector, stopping the rearward motion of the slide and precluding injury to the shooter. | ||||||
| 123 | Firing mechanism for pistols | US235073 | 1981-02-17 | US4369593A | 1983-01-25 | Ulrich Zedrosser; Satish K. Malhotra |
| A firing mechanism for a pistol comprises a firing pin, a hammer for striking on the firing pin, a hammer spring biasing the hammer, and a catch lever for temporarily locking the hammer in a cocked position is designed to have a safety function. In order to provide a structurally simple mechanism which provides perfect safety against an unintended discharge of a shot without need for additional parts, the catch lever is provided with two locking surfaces. When the hammer is uncocked, the firing pin bears on one of said locking surfaces in the firing direction and the hammer bears on the other of said locking surfaces in the striking sense. | ||||||
| 124 | Automatic pistol | US37128273 | 1973-06-18 | US3894474A | 1975-07-15 | TANFOGLIO GIUSEPPE |
| Automatic pistol which comprises a breechblock-carrier disassemblable only when the pistol is in a non-firing position and only by means of an upward angular displacement of the rear portion of the breechblock, and which further comprises an ejection mechanism for the shell, which mechanism is made of a single unit comprising a snap latch displaceable with said unit.

| 125 | Machine gun | US3756119D | 1971-12-14 | US3756119A | 1973-09-04 | CURTIS G; TATRO H |
| The machine gun of this invention features a unitary bolt and bolt drive assembly reciprocably mounted within a receiver along three longitudinally extending bearing supports symmetrically arranged in spaced relation to the receiver; the bolt and bolt drive assembly, together with a recoil buffer constituting an integral operating group removably maintained within the receiver by a single latch mechanism; a bolt carrier of the assembly incorporating actuating means for cartridge belt advance, cartridge extraction and ejection; the bolt carrier housing not only a rotary, front-locking bolt but also a cam follower which fixes a firing pin to the carrier and moves within a contoured slot in the bolt for locking and unlocking it in battery. This machine gun also features a gas recoil system for the bolt and bolt drive assembly having anti-fouling porting means for purging gas from the system under high pressure after firing; an ejector operated by the recoiling bolt and bolt drive assembly independently of its velocity; an automatically engageable, selfaligning barrel and receiver latch construction; and a sight assembly featuring a zero backlash precision screw adjustment means.

| 126 | Striker assembly for firearms | US3713241D | 1970-02-11 | US3713241A | 1973-01-30 | DIECKMANN R |
| A striker assembly for firearms which is bodily removable as an integral assembly from the receiver of the firearm without the need for disassembly of any other parts of the firearm. A body member supports a pivotally mounted spring loaded hammer and a pivotally mounted spring loaded sear, both of which are removably mounted on the body member, and there are cooperating locking means on the receiver and body member engageable in response to insertion of the assembly into the receiver. An ejector element is also mounted on the body member and assists both in retaining the parts in assembled relationship and in retaining the assembly in a fixed position in the receiver.

| 127 | Ejection system for a firearm | US3561148D | 1968-10-21 | US3561148A | 1971-02-09 | MAILLARD BERNARD |
| THE INJECTION SYSTEM INCLUDES AN EXTRACTOR CARRIED BY THE MOVABLE BREECH MECHANISM AND, DIAMETRICALLY OPPOSITE AN EJECTOR CARRIED BY THE BREECHCASE. THE FRONT OF THE EJECTOR HAS A TRANSVERSE STRIKING SURFACE FOR THE REAR EDGE OF THE CARTRIDGE CASE TO BE EJECTED. THE EJECTOR IS CONTROLLED BY THE BREECH MECHANISM SO AS TO PRESENT THE STRIKING SURFACE AGAINST THE REAR EDGE DURING THE RECOIL OF THE BREECH MECHANISM. AT THE FRONT OF THE STRIKING SURFACE IS A PROJECTION WHICH STRIKES THE LATERAL SURFACE OF THE CARTIDGE CASE TRANSVERSELY BEFORE THE IMPACT OF THE STRIKING SURFACE WITH THE REAR-EDGE. THIS TIPS THE CARTIDGE CASE BEFORE THE IMPACT IN THE DIRECTION OF THE EJECTION PASSAGE, THUS ATTENUATING THE VIOLENCE OF THIS IMPACT.
