Abstract

27,821. Schwarzlose, A. W. Dec. 9, 1910, [Convention date]. Breech actions, sliding breech-block; firing-appliances applicable generally. - Relates to automatic guns in which the action is enclosed in a casing and in which the handle of the breech - block projects through a slot in the casing, and consists (1) in forming the breechblock of two telescopic parts, and (2) in a special trigger mechanism. When the breech is closed, the two parts s, c of the breech-block are extended by an interposed spring and completely close the slot in which the handle slides; when the breech is opened the front part c telescopes into the rear part s, as shown in Fig. 2, thus shortening the necessary length of casing. In the construction shown in Fig. 1, the rear part s of the breech-block is driven forwards by the firing-spring f<2>, the sear a being pivoted on this rear part, and the front part c is pressed forwards by a spring f'. In the construction shown in Fig. 3, the front part c is driven forwards by the spring f<2>, which passes right through the hollow firing-pin b, and the rear part is pressed rearwards by the firing-spring f<3>. The trigger z is formed with two fulcrums z<1>, z<2> the rear one of which is fitted in an undercut recess in the casing. In the construction shown in Fig. 1, the sear a is mounted on trunnions in slots in the rear part of the breech-block so as to be capable of a slight longitudinal movement to enable it to be engaged by the inturned lips z<3>, Figs. 1 and 6, of the trigger.
