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 7):
The recoil inversion assembly of  claim 1 , wherein the recoil force transmitting means ( 100 ) comprises the fulcrum ( 23 ) being connected to an opposite end of the inversion lever ( 10 ) and including a pinion ( 15 ) rotatable with rotation of the inversion lever ( 10 ), a rack ( 25 ) connected to a rear end of the recoil rod ( 12 ), the rack including teeth meshed with the pinion ( 15 ) for moving the rack and recoil rod forwardly when the pinion rotates during a beginning of a firing cycle, and a stop ( 4 ) in the frame for holding a forward end of the recoil spring ( 13 ), the rack being engaged with an opposite end of the recoil spring for compressing the recoil spring when the rack moves forwardly in the frame, and a counter weight ( 12 a ) at a forward end of recoil rod ( 12 ) for transferring weight forwardly during a firing cycle, a cover ( 4 ) on the firearm frame for covering the slider, the recoil spring and the recoil rod, the cover including an aperture ( 4 a ) for slidably receiving the counter weight.
