Abstract

415,841. Automatic guns. BRONDBY, F. N., 66, Gjetemyrsveien, Oslo, Norway. April 7, 1933, No. 10479. Convention date, July 21, 1932. [Classes 92 (ii) and 119.] Relates to breech actions for machine guns or automatic small arms of the kind in which the breech block 7 carries a transverse locking-bolt 15 operated by the movements of an actuating-slide or striker-post 14 relatively to the breech block, the rearward movement of the slide after releasing the locking-bolt serving to open the breech and the forward movement of the slide after closing the breech serving to lock it. The invention comprises in combination the following features, (1) inclines 19<a>, 19<b> on the slide which engage inclines 18<a>, 18<b> on lateral projections on the locking bolt to move the bolt into and out of engagement with a stop face 17 on the breech frame ; (2) an extension x of the slide which moves idly over the locking-bolt prior to unlocking and after locking; and (3) a locking- bolt which by pressure on the surface 2 of the breech casing during forward movement of the slide transmits through the inclines 19<a>, 18<a> the closing force to the breech block. The stop face 17 is slightly inclined to permit of ready release of the locking bolt and to convey a forward closing pressure to the breech block at the instant of locking.
