| 41 | ELASTOMERIC EXTRACTOR MEMBER | EP14739597.4 | 2014-03-12 | EP2972052A1 | 2016-01-20 | FEESE, Devin; STONE, Jeffrey, W. |
| A biasing member (14) for a bolt assembly (2) of a firearm (F) is described herein. The biasing member (14) comprises a body (40) having a first portion (43) configured to engage and seat within a biasing member receiving indentation (33) of an arm (30) of the extractor (6), and a second portion (45) configured to engage and seat within a receiving area (33) along a bolt (4) of the firearm (F). The body (40) provides a biasing force directed against the extractor arm (30). The body (40) comprises an elastomeric material, and is configured such that the first (43) and second portions (45) provide varying levels of compression sufficient to maintain a substantially constant extractor tension between the extractor arm (30) and a cartridge. | ||||||
| 42 | FIREARM BARREL HAVING CARTRIDGE CHAMBER PREPARATION FACILITATING EFFICIENT CARTRIDGE CASE EXTRACTION AND PROTECTION AGAINST PREMATURE BOLT FAILURE | EP13829342.8 | 2013-06-25 | EP2867606A2 | 2015-05-06 | 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. | ||||||

A firearm (20) including a receiver (30), a barrel (22) , a breech bolt assembly (42), and a trigger assembly (32). The bolt assembly (42) has a bolt (50)including a body portion (56), a lug portion (90), and a firing pin bore (44). The lug portion (90) includes outward extending lugs (110), a cartridge recess (92), and an off-center hole (96). The bolt assembly (42) also includes an extractor (46) and an ejector pin (98). At least some of the lugs (110) on the lug portion (90) of the bolt (42) have a tapering outer face (120) so that a rearward face (116) of the respective lug (110) is taller than a forward face (114) of the respective lug (110). In another embodiment, at least some of the lugs (110) on the lug portion (90) of the bolt (42) have tapering side faces (122,124) so that a rearward face (116) of the respective lug (110) is wider than a forward face (114) of the respective lug (110).

A locking and recocking assembly with swivel breech-lock and rotating locking head particularly designed for inertially-actuated weapons, which combines in a single assembly all the functions for locking, opening, case ejection and recocking with locking return, required for correct operation of the weapon; those functions were, until now assigned to various components variously assembled on the weapon. The locking and recocking assembly with swivel breech-lock and rotating locking head has the entire mass, required for inertial operation, concentrated in the swivel breech-lock, which is accommodated completely within the supporting structure of the weapon, such as the sheath or barrel extension or breech of the weapon. All this leads to better balancing and stability of the weapon, higher reliability in operation, greater constructive simplicity and ease of assembly and disassembly.

| The invention relates to a locking device which can be mounted in a hand gun and which comprises a lock (1) that is moveably arranged in a housing in the longitudinal direction of the weapon and that consists of a lock carrier (3) and of a lock head (5) which is embodied in such a way that it can be mounted in the weapon in at least two different positions. The locking device also comprises an extractor (25) which is laterally fixed to the lock head (5) and entrains a cartridge case when the lock (1) is removed, whereby the cartridge case is situated in the barrel. The inventive device further comprises a trigger (7) that is integrated into the locking device. The trigger (7) removes the cartridge case from the lock (1) after said cartridge case has been extracted from the barrel. The locking device is characterised in that the lock carrier is provided with at least two longitudinal holes (47a, 47b) which serve as connecting links and in that the lock head is provided with a pin (41) which engages with one longitudinal hole (47a, 47b) according to the mounting position of the lock head. | ||||||

| The machine-pistol with an obturator (12) which extends longitudinally, so to surround with a cylindrical or semicylindrical portion, in its putforward shooting position, a longitudinal length of the barrel (13). The obturator is thus suitable both for the axial and for the radial or piezoelectric percussion. By optionally mounting in the weapon the obturator and the barrel of the desired configuration, the weapon is able to use different types of cartridges, both with case and caseless. | ||||||
| 53 | Machine pistol with retarded blowback | EP84307930 | 1984-11-15 | EP0159441A3 | 1986-08-27 | 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). |

Vor dem Auswerfen der leeren Patronenhülse (13) wird diese durch einen Auszieher (16,34,47) aus dem Patronentager des Waffenrohres herausgezogen und anschliessend durch einen Auswerfer (20) gekippt, wobei auf den schwenkbar gelagerten Auszieher (16,34,47) grosse Kräfte ausgeübt werden. Es hat sich gezeigt, dass bei grosser Kadenz die Federkräfte zu klein sind, um den Auszieher (16.34,47) zuverlässig festzuhalten. Erfindungsgemäss wird daher der Auszieher (16,34,47) durch einen Stützhebel (25) oder durch eine Verriegelungsklinke (41,54) während des Kippens der Patronen gegen eine unbeabsichtigte Verschwenkung gesichert. Vorzugsweise ist noch ein Stützhebel (67) oder Stützschieber (59) im Verschluss (10) angeordnet, der ein vorzeitiges Kippen der Patrone (13) verhindert. |
