Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
190 words
An automatic firearm, particularly a gas-operated firearm having a reciprocating breech block and a cartridge feeding device which is controlled by the gas pressure during the firing of a cartridge to feed a series of cartridges in succession to the cartridge chamber of a gun barrel, comprising a coupling and indexing mechanism including a member shiftable by gas pressure generated by the firing of a cartridge and a rotatable coupling part connected to said member and rotated thereby, a cartridge feeding device including a transversely movable housing with first and second transversely spaced rotatable cartridge feeding stars which are rotatable to feed cartridges in succession to the barrel cartridge chamber, said cartridge feeding device being shiftable to align a respective one of said first and second stars in operative positions in respect to said rotatable coupling and the cartridge chamber, said stars being selectively and alternatively alignable in an operative position and each star having a shaft with a coupling portion which is separately engageable with said rotatable coupling when in an operative position whereby to connect the associated star so as to feed the ammunition to the cartridge chamber.
Claim 2
Dependent Claim
190 words
An automatic firearm, particularly a gas-operated firearm having a reciprocating breech block and a cartridge feeding device which is controlled by the gas pressure during the firing of a cartridge to feed a series of cartridges in succession to the cartridge chamber of a gun barrel, comprising a coupling and indexing mechanism including a member shiftable by gas pressure generated by the firing of a cartridge and a rotatable coupling part connected to said member and rotated thereby, a cartridge feeding device including a transversely movable housing with first and second transversely spaced rotatable cartridge feeding stars which are rotatable to feed cartridges in succession to the barrel cartridge chamber, said cartridge feeding device being shiftable to align a respective one of said first and second stars in operative positions in respect to said rotatable coupling and the cartridge chamber, said stars being selectively and alternatively alignable in an operative position and each star having a shaft with a coupling portion which is separately engageable with said rotatable coupling when in an operative position whereby to connect the associated star so as to feed the ammunition to the cartridge chamber.
Claim 3
Dependent Claim
59 words
An automatic firearm, according to claim 1, wherein said coupling and indexing mechanism includes a cylinder, said member comprising a piston shiftable in said cylinder, means for connecting gas pressure generated in the gun barrel cartridge chamber during the firing of a cartridge to said cylinder to displace said piston, said piston being connected to rotate said rotatable coupling.
Claim 4
Dependent Claim
28 words
An automatic firearm, according to claim 2, wherein said piston includes a rack portion, said rotatable coupling part comprising a pinion in meshing engagement with said rack portion.
Claim 5
Dependent Claim
52 words
An automatic firearm, according to claim 3, wherein each of said first and second rotatable stars includes a central rotatable shaft having a shaft coupling formation at its end, said shaft coupling formation being engageable with said rotatable coupling, said rotatable coupling comprising first and second rotatable gears engageable with said rack.
Claim 6
Dependent Claim
21 words
An automatic firearm, according to claim 1, wherein said rotatable stars each include a shaft coupling part having a T-shape groove.
Claim 7
Dependent Claim
39 words
An automatic firearm, according to claim 1, including a bar-type magazine located between said rotatable stars for receiving a third type of ammunition and having a downwardly feeding discharge for the cartridges located between said first and second stars.
