Handgun apparatus

Claim 2

A recoil energy absorption apparatus for use in a handgun comprising: a cylinder; a first piston assembly, said first piston assembly mounted within said cylinder forming a closed chamber, a gas located within said cylinder, due to said closed chamber as said first piston assembly moves into said cylinder the gas compresses increasing energy absorption; a recoil spring having a pair of ends; a second piston assembly, said second piston assembly in direct contact with one of said pair of ends of said recoil spring, the other of said ends of said recoil spring being fixedly positioned to move with said first piston assembly; and said first piston assembly including a pair of spaced apart members, a non-metallic resilient energy absorption material located between said members, whereby said resilient material being adapted to absorb a portion of the recoil energy.

Claim 3

In combination with a semi-automatic hand gun which has a barrel mounted within a slide, said barrel terminating in a firing chamber at its inner end, said slide mounted for longitudinal movement upon a trigger housing between a cartridge firing position and a cartridge ejecting position, said trigger housing including a recoil absorbing chamber, said slide having attached thereto a plug housing said plug housing being movable within said recoil absorbing chamber the improvement comprising: a recoil absorber assembly located within said recoil absorbing chamber, said recoil absorber assembly located between said trigger housing and said slide so as to absorb a recoil force, said recoil absorber assembly including a first piston assembly, said first piston assembly being mounted within a cylinder, a fluid to be contained within said cylinder, during movement of said slide from said cartridge firing position to said cartridge ejection position said cylinder with said fluid to absorb a portion of the energy of said recoil force; and there being a link pivotally connecting said barrel to said trigger housing, said recoil absorber assembly including a second piston, a recoil spring located within said recoil absorbing chamber and being in direct connection with said second piston, said second piston being in contact with said link, whereby the recoil spring force is transferred through said recoil absorber assembly directly to said link.

Claim 4

In combination with a semi-automatic hand gun which has a barrel mounted within a slide, said barrel terminating in a firing chamber at its inner end, said slide mounted for longitudinal movement upon a trigger housing between a cartridge firing position and a cartridge ejecting position, said trigger housing including a recoil absorbing chamber, said slide having attached thereto a plug housing said plug housing being movable within said recoil absorbing chamber the improvement comprising: a recoil absorber assembly located within said recoil absorbing chamber, said recoil absorber assembly located between said trigger housing and said slide so as to absorb a recoil force, said recoil absorber assembly including a first piston assembly, said first piston assembly being mounted within a cylinder, a fluid to be contained within said cylinder, during movement of said slide from said cartridge firing position to said cartridge ejection position said cylinder with said fluid to absorb a portion of the energy of said recoil force; and there being a link pivotally connecting said barrel to said trigger housing, said recoil absorber assembly including a second piston, a recoil spring located within said recoil absorbing chamber and being in direct connection with said second piston, said second piston being in contact with said link, whereby the recoil spring force is transferred through said recoil absorber assembly directly to said link.

Claim 5

The combination as defined in claim 2 wherein: said barrel having a locking lug assembly, said slide having a locking recess assembly, a protuberance formed upon said link, a means under a constant biasing force being in continuous contact with said protuberance, with said slide in said cartridge firing position the biasing force of said means being transferred through said protuberance so as to apply a torque in respect to said link tending to maintain said locking lug assembly of said barrel into full cooperation with said locking recess assembly formed within said slide, with said slide in said cartridge ejecting position the biasing force of said means being transferred through said protuberance into said link so as to exert a torque about said link tending to maintain said locking lug assembly disassociated from said locking recess assembly; with said slide in said cartridge firing position said barrel having a locking lug assembly which cooperates within a locking recess assembly formed within said slide.

Claim 6

The combination as defined in claim 3 wherein: said link having a sleeve, said sleeve having an opening therethrough, said second pivot pin to be conducted through said opening, said opening being eccentrically located with respect to said sleeve, said sleeve being adjustably movable within said link to various positions and fixable in a particular said position by fixing means located within said link.

Claim 7

The combination as defined in claim 2 wherein: the free end of said recoil spring being directly connected with a recoil spring plug, said recoil spring plug having a tapered body, said recoil spring plug to connected with a barrel bushing, said tapering of said plug to effect a tight interfit between said barrel bushing and said plug, said barrel bushing to be located about said barrel and capable of slidable movement in respect thereto, said barrel bushing being fixedly positioned within said slide.

Claim 8

The combination as defined in claim 5 wherein: with said slide in said cartridge firing position said barrel having a locking lug assembly which cooperates within a locking recess assembly formed in said slide; with said slide in said cartridge firing position there being a connecting means connected between said bushing assembly and said barrel to exert a longitudinal biasing force on said barrel tending to hold the forward edge of said locking lug assembly against the aft edge of said locking recess assembly.

Claim 9

The combination as defined in claim 6 wherein: the periphery of the free end of said barrel being a circumference slightly greater than the circumference of the remaining portion of said barrel, said bushing assembly including a barrel bushing directly connected to said slide and an inner bushing supported within said barrel bushing, said inner bushing to be in direct contact with said barrel, the size of the opening through said inner bushing being slightly smaller than the size of said periphery of said free end of said barrel, whereby as said slide is moved from said cartridge ejection position to said cartridge firing position a press fit occurs between said inner bushing and said periphery of said free end of said barrel as said slide is moved to said cartridge firing position.

Claim 10

The combination as defined in claim 7 wherein: said inner bearing being constructed of a plastic material and providing a low frictional interconnection between said inner bearing and said barrel.
