Abstract
575,000. Automatic smallarms. WESTERN CARTRIDGE CO. Aug. 6, 1943, No. 12748. Convention date, Jan. 29. [Class 119] In order to ensure the re-engagement of the sear of a semi-automatic rifle with the bent of a pivoted hammer after each discharge, although the trigger may still be held pulled, the hammer 29 is formed with two bents 32, 33, which are relatively displaced so that when the hammer is thrown back by the recoiling breech-bolt, to an overcocked position shown in Fig. 3, the rear bent 33 will be engaged by a spring-pressed secondary sear 56, Fig. 10, which is pivoted in a recess 54 in the trigger 42, Fig. 11, on the trigger axis-pin 44. The spring 58 of the sear 56 operates between the sear and the trigger. The main sear 51 is integral with the trigger. The trigger spring 48 acts upwardly upon a front extension 45 of the trigger, and such extension engages a front extension 57 of the pivoted sear 56 when the trigger is rocked counterclockwise by its spring 48. The main hammer-bent 32 is backed by an incline 34. When the weapon is fired, the hammer is pushed back and caught by the spring sear 56. Upon relaxation of the finger pressure on the trigger, the latter is rocked by its spring 48 and the engagement of the projections 45, 57 causes the sear 56 to be released. Thereupon, the hammer is moved by its spring 37 and the incline 34 engages the nose 52 of the triggersear 51 and causes engagement of the sear with the bent 32. The forward thrust on the sear and trigger caused by the incline 34 brings a slope 63 on the secondary sear 56 into contact with a slope 35 below the secondary bent 33 of the hammer, so that, as the trigger is pulled to fire the next shot, it has first to compress its spring 48 alone and then to compress also the secondary-sear spring 58, thus giving a double-pull. The hammer is mounted in the manner set forth in Specification 571,726.
