Abstract

659,179. Smallarms. ZBROJOVKA BRNO, NARODNI PODNIK. Feb. 7, 1949, No. 3351. Convention date, Feb. 16, 1948. [Class 119] The barrel 1 of an automatic firearm has its rear end extending into the breech casing 3, which end is cooled by a current of air produced by the reciprocating movements of the breechblock 5. This effect is achieved by forming the front end of a guide rod 7 as a piston 9 working in a bore 10 of the breech block and by providing in a part of the breech-block, which embraces the rear end of the barrel holes 11 through which the air passes from the bore to the space around the barrel. The breechblock return spring is indicated at 8.
