Claim 5

The combination as defined in claim 2 wherein: the periphery of said sleeve having a plurality of spaced apart notches, said fixing means comprises a pin which is securable within said link and cooperating with any one of said notches.

Claim 6

An adjustable link to interconnect the barrel of a firearm to a fixed housing within a firearm, said adjustable link comprising: a first opening therethrough and a second opening therethrough, said opening being spaced from said second opening, said first opening adapted to cooperate with a first pivot pin to pivotally attach said link to the barrel of a handgun, said second opening to receive a sleeve therein, said sleeve having a third opening therethrough, said third opening being eccentric with respect to said sleeve, said third opening being adapted to cooperate with a second pivot pin to pivotally attach said link to a fixed housing within a handgun, the periphery of said sleeve having a plurality of spaced apart notches, an attaching pin fixedly positioned within said link to cooperate with one of said notches.

Claim 7

An adjustable link to interconnect the barrel of a firearm to a fixed housing within a firearm, said adjustable link comprising: a first opening therethrough and a second opening therethrough, said opening being spaced from said second opening, said first opening adapted to cooperate with a first pivot pin to pivotally attach said link to the barrel of a handgun, said second opening to receive a sleeve therein, said sleeve having a third opening therethrough, said third opening being eccentric with respect to said sleeve, said third opening being adapted to cooperate with a second pivot pin to pivotally attach said link to a fixed housing within a handgun, the periphery of said sleeve having a plurality of spaced apart notches, an attaching pin fixedly positioned within said link to cooperate with one of said notches.

Claim 8

The link as defined in claim 4 wherein: a protuberance connected to said link adjacent said second opening and extending radially outward in respect thereto.

Claim 9

In combination with a semi-automatic handgun which has a barrel mounted within a slide, said barrel terminating in a firing chamber at its inner end, a link pivotally connected by a first pivot pin to said barrel at said inner end, said slide mounted for longitudinal movement upon a handgrip housing, said slide being movable between a cartridge firing position and a cartridge ejecting position, 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, said link being pivotally connected by a second pivot pin to said handgrip housing, a trigger connected to said handgrip housing, said trigger to be capable of causing firing of a cartridge located within said firing chamber, the improvement comprising: said link having a peripheral surface from which extends a protuberance, said protuberance having a forward edge and a rearward edge, a means under constant biasing force being in continuous contact with said protuberance, with said slide in said cartridge firing position said means being in contact with said forward edge causing a torque level about said second pivot pin tending to maintain said locking lug assembly into full cooperation with said locking recess assembly formed within said slide, with said slide in said cartridge ejecting position said means being in contact with said rearward edge causing a torque to be produced in a direction opposite to the direction of said torque level which tends to maintain said locking lug assembly disassociated from said locking recess assembly.

Claim 10
