Abstract

219,932. Browning, J. M. July 31, 1923, [Convention date]. Machine guns.-Relates to automatic machine guns of the kind described in Specifications 133,329. 133,351, and 133,352 in which the barrel 13 and breech-block 17 recoil together for a limited distance and are then unlocked to permit the breech-block to recoil alone to open the breech and store energy in a reaction spring which finally returns all the parts to the firing position. The present invention consists mainly in adapting the gun to fire larger charges by providing a strong casing containing an adjustable spring. controlled liquid brake 18 to cushion the recoiling parts. The casing is of hollow beam construction comprising side plates 1 united by rivets to a front plate 2, top and bottom plates 4, 3 having flanges with ribs sliding in grooves on the side plates and fastened by rivets, and a vertically slidable rear plate 5. The breech-block 17 guided in the barrel extension 15 is locked thereto by a vertically-sliding bolt 58 mounted in the extension. The bolt carries pins 58<a> which en. gage with fixed members 18a on the brake. to lower the bolt during the first part of the recoil movement, During further recoil, the barrel extension engages acam-lever 35 which gives a kick to the breech-block to move it to rear position against the action of the return spring 36 (see breech-block plan, Fig. 13), such movement being cushioned by a buffer 6 mounted on the rear plate. The barrel extension is linked' to the piston-rod 23 of a liquid brake 18 through the medium of a sliding washer 27 which bears against a spring 20 mounted between the washer and a fixed diaphragm 29. The diaphragm has a stuffing-box 24 for the piston-rod and a safetyvalve 25 for the escape of excess liquid. The piston comprises an apertured disc 22 fast with the piston-rod and a loose apertured disc 32 movable longitudinally relatively to the disc 22 but feathered in the brake cylinder 21 which is rotated to adjust the brake. For cooling the gun, the barrel 13 is ribbed and the barrel casing 14 is provided with staggered air passages, further air passages x being formed in the front plate 2. To disassemble the gun, the rear plate is slid upwardly after releasing a catch 11. The barrel, breech-block, and brake, parts can then be withdrawn rearwardly after removing the return spring and its guide rod in one unit. The Specification as open to inspection under Sect. 91 (3) (a) also describes the firing- mechanism forming the subject-matter of Specification 225,577, and the cartridge-feed mechanism forming the subject-matter of Specification 225,578. This subject-matter does not appear in the Specification as accepted.
