Abstract:
A recoil inversion assembly for firearms having frame, barrel for a cartridge, bolt movable during a firing cycle, firing mechanism for firing the cartridge and recoil rod with recoil spring. The recoil inversion assembly has a transfer arm with one end pivotally connected to the bolt at a bolt axis, a guide slot in the frame for slidably receiving the bolt axis as the bolt moves during a firing cycle, an inversion lever having one end pivotally connected to the opposite end of the transfer arm, a fulcrum engaged with the inversion lever for rotation of the inversion arm with respect to the frame and recoil force transmitting mechanism connected to the inversion lever for transmitting rotation of the inversion level to the recoil spring for compressing the spring such that blowback during a firing cycle is transferred through the recoil inversion assembly to the recoil spring.

Claim (Index 1):
A recoil inversion assembly for a firearm having a frame ( 1 ,  40 ), a barrel ( 2 ,  34 ) with a breach end for a cartridge ( 3 ), a bolt ( 6 ,  36 ) movable due to blowback away from the breach end of the barrel during a firing cycle, a firing mechanism ( 110 ,  112 ,  114 ) for firing the cartridge, and a recoil rod ( 12 ,  42 ) with recoil spring ( 13 ,  44 ) for moving the bolt toward the breach end of the barrel at an end of a firing cycle, the recoil inversion assembly comprising:\n a transfer arm ( 8 ,  28 ) having one end pivotally connected to the bolt ( 6 ,  36 ) at a bolt axis ( 7 ), and an opposite end; a guide ( 1 a ) in the frame ( 1 ,  40 ) for slidably receiving the bolt axis ( 7 ) to move of the bolt axis as the bolt ( 6 ,  36 ) moves during a firing cycle; an inversion lever ( 10 ,  30 ) having one end pivotally connected at a spring loaded pivot junction ( 11 ) to the opposite end of the transfer arm ( 8 ,  28 ); a fulcrum ( 23 ,  32 ) engaged with the inversion lever ( 10 ,  30 ) for rotation of the inversion lever ( 10 ,  30 ) with respect to the frame ( 1 ,  40 ); a slider ( 5 ,  35 ) having a slider surface against which the pivot journal is engaged before a firing cycle begins for locking the bolt against the breach end of the barrel during an initial phase of a firing cycle, the pivot journal sliding along the slide surface during the initial phase until the pivot journal slides off the slider surface to allow rearward movement of the bolt; and recoil force transmitting means ( 100 ) connected to the inversion lever ( 10 ) for transmitting rotation of the inversion level to the recoil spring ( 13 ) for compressing the recoil spring ( 13 ), such that blowback during a firing cycle is transferred through the recoil inversion assembly to the recoil spring.
