| 82 | Machine pistol with retarded blowback | EP84307930.2 | 1984-11-15 | EP0159441A2 | 1985-10-30 | Gillum, Richard R. |
A machine pistol includes means for retarding blowback of the slide assembly (100). The pistol has both right hand and left hand stocks (12, 13) to enable the weapon to be fired from a comfortable visual sighting position at eye level with the wrist axes perpendicular to one another. The slide assembly (100) includes a bolt (110) which carries the firing pin (129), extractor and ejector and which reciprocates relative to the receiver (20) and barrel (60), and a tubular cylindrical muzzle sleeve (140) releasably connected to the forward end of the bolt (110) and which fits coaxially around the barrel (60). A coaxial helical spring (65) is provided between the barrel (60) and muzzle sleeve (140) to urge the muzzle sleeve (and bolt) to the forward firing position in which the forward end of the muzzle sleeve extends outwardly beyond the end of the barrel. A plurality of annular internal grooves (150) are formed in the forward end of the muzzle sleeve (140) so that the momentum of the escaping gases immediately following firing exerts a force against the sidewalls (152) of the grooves to retard blowback of the slide assembly (100). |

| 84 | Cartridge extractor for firearms | EP80301110.5 | 1980-04-08 | EP0017506A1 | 1980-10-15 | Rowlands, Kenneth Charles |
A cartridge extractor, comprising a resilient ring segment (21) formed with a claw (30), is mounted without a rivet in a recess (15) in the face of a firearm bolt (22). The bolt recess is formed with an arcuate clearance cut (31) and with radius cuts (27,28) at either end of the clearance cut. The ring segment has its free ends bent outwardly to form detent arms (23,24), which seat in the radius cuts to support the claw in position to engage a cartridge case as it enters the recess. This entry deflects the ring segment into the clearance cut. When the claw seats in the base of the cartridge, the ring segment is repositioned by the detent arms sliding back into the radius cuts. A pin (35). or other means may be added to prevent relative rotation of the ring segment, without interfering with its normal deflection. |

| 85 | SEMIAUTOMATIC FIREARM | PCT/US2015031210 | 2015-05-15 | WO2015179248A9 | 2016-01-14 | KOLEV IVAN; LINSCOTT JOHN |
| Cooperating mechanisms provide a reliable and robust semiautomatic firearm particularly suitable for firing necked rimfire cartridges. A reciprocating bolt assembly has delayed blowback and a firing pin block. Features prevent out-of-battery firing, when the bolt assembly is not fully engaged to the firing chamber or barrel face, a movable member within a bolt body functions as a blocking member that blocks the firing pin and prevents the firing pin from striking a cartridge. In embodiments, the firing pin has two stop portions that the movable member can engage depending on the cycle status of the firearm. A reverse cam mechanism associated with the firing pin blocking provides a resistance to and delays blowback. The bolt may interface with the necked rimfire cartridge using a undercut engagement on the forward end of the bolt. The semiautomaticfirearm also may incorporate one or both of a dual trigger arrangement as part of a trigger and firing mechanism with redundant hammer block and safety features, and trigger pull adjustment. | ||||||
| 86 | FIREARM BARREL HAVING CARTRIDGE CHAMBER PREPARATION FACILITATING EFFICIENT CARTRIDGE CASE EXTRACTION AND PROTECTION AGAINST PREMATURE BOLT FAILURE | PCT/US2013047724 | 2013-06-25 | WO2014028127A2 | 2014-02-20 | LARUE MARK C |
| To permit ease and efficiency for the extraction of spent cartridge cases from the cartridge chamber of a firearm barrel within a wide range of temperature conditions, the internal tapered surface of the body region of a cartridge chamber is prepared by establishing circumferentially spaced longitudinal straight or curved regions of the internal surface finish to create an internal cartridge chamber geometry having gradually tapered spaced longitudinally relieved linear or spiral areas having longitudinal linear or spiral lands between each of the relieved areas. The circumferentially spaced lands develop controlled impedance to rearward cartridge case movement on cartridge firing to effectively protect the bolt and extractor mechanisms of the firearm against early failure. | ||||||

| 98 | Biased pivoting cartridge extractor for blowback bolt firearms | US15711822 | 2017-09-21 | US20180087857A1 | 2018-03-29 | David M. Davis; Russell E. Klawunn |
| A biased pivoting spent ammunition cartridge case extractor and retainer mechanism for blowback bolt firearms. The mechanism includes a distal arcuate hook shaped and dimensioned to intimately engage and nest into part of the circumferential groove in front of the cartridge rim. The hook remains engaged during blowback extraction of the casing from the chamber, and prior to ejection of the case from the firearm. The hook is formed onto the distal end of a rocking member secured to the bolt by a medial pivot. A compression spring bears against the opposite, proximal end of the rocking member thereby biasing the hook inwardly toward the counterbore seat on the distal end of the bolt into which the base of the case rests during extraction. A direct gas impingement system overcomes the biasing force of the spring to cause the case to be ejected. | ||||||
