Abstract

678,000. Machine gun cartridge feed. BREVETS AERO-MECANIQUES SOC. ANON. June 9, 1949. [June 19, 1948] No. 15413/49. Class 92 (ii). Relates to cartridge-belt feed mechanism of the type in which the belt is fed, a distance equal to the pitch of the cartridges, in two steps by a sliding breech block, the first step during the recoil stroke of the block and the second during its forward movement. According to the invention, the first step is effected only during the latter part of the recoil stroke. The invention is shown applied to an automatic gun in which the breech block 5 reciprocates in a barrel-extension 3, the oppositely-moving parts 9, 10 of the belt-feed slide carrying the step-by-step actuating pawls 11, 12 respectively being operated by a roller 22 on the breech block engaging a cam member 17 pivoted at 18 to the barrel extension 3. The cam member operates, through a slide 21 and pin 20, a lever 13 pivoted at its rear end to the hinged cover 7, Fig. 3, which also carries the parts 9, 10 of the belt feed slide. The front slotted end of the lever 13 engages directly with the part 10 and indirectly through a reversing lever 15 with the part 9. During recoil, and after an idle movement to the right of pin 22, the cam part 17a of member 17 (see Part II, Fig. 5) becomes effective to move a cartridge 2 shown in waiting position, to a central loadingposition, and during the return movement of the breech block this cartridge (see Part IV, Fig. 5) is loaded into the gun chamber, the cam part 17b being then effective to bring a second cartridge to waiting position. The breech block roller 22 is shown in Fig. 3 with an auxiliary roller 23 engaging a rail 24 on the barrel-extension to take up side strain as the lever 17 is engaged. This auxiliary roller arrangement, with modifications thereof, form the subject-matter of divided Specification 678,078.
