(01. 42-69) 1 2 This invention relates to an adjustable and ac are spaced apart and form a housing for receiv curate trigger stop for ?rearms for locating the ing the trigger 26, the latter being pivoted thereto trigger in correct position while the trigger is in on a pin 28. , Pivoted t0 the trigger at 30 there is non-?ring condition. a disconnector lever 32 which is similar in- form Objects of the invention include the provision to that disclosed in my Patent No. 2,356,726. This . of a trigger stop for ?rearms for maintaining the disconnector lever is provided with a shoulder 34 having engagement with a complementary trigger in correct position in non-?ring condi tion thereof and comprising a housing mount shoulder 36 on a sear 38 pivoted at 40 to the legs ing the trigger and the sear and a?ixed to the 22 and 24. The sear 38 is provided with a nose receiver of the ?rearm, said housing including 10 42 extending upwardly through an aperture in a pair of spaced depending legs between which the receiver for engagement with a shoulder 44 the trigger is pivoted, there being an adjustable on the hammer iii. A sear spring 46 normally stop mounted on one of the legs for engagement urges the sear in a counterclockwise direction with a rear face of the trigger to stop the same so as to bring the nose 42 up into the path of in desired position, said stop being easily ad the hammer. There is a disconnector spring 48 justable as desired. interposed between the lower edge of the discon nector 32 and a surface of the trigger 26 so that Further objects of the invention include the the disconnector lever is normally urged in a provision of a ?rearm comprising a hammer, a clockwise direction. A trigger spring 50 bears sear for the hammer, a trigger, and a. discon nector lever pivoted to the trigger and having 20 against the trigger and forces it in a clockwise an engagement with the sear for actuating the direction from the dotted line ?ring position same upon movement of the trigger to ?ring posi thereof to the solid line non-?ring position. In leg 22 only of the trigger housing there is tion, said sear, disconnector lever, and trigger'all being mounted on a single housing secured to the formed a drilled and tapped hole for receiving receiver of the ?rearm, said housing being pro- ~ a machine screw or the like 52 having a head 54. vided with an adjustable element for positioning The head 54 is contained within a recess 56 so the trigger and hence locating the disconnector that the head 54 may stop short of the rear sur lever in non-?ring position of the ?rearm. face of the leg 22.
