Device for universal charging and metering for cartridges in box magazines
The proposed invention relates to small arms, specifically to charging devices for charging magazines with cartridges and to meters for cartridges in box magazines. The technical result consists in providing a universal charging device and meter for cartridges in box magazines which makes it possible to achieve rapid charging and discharging of cartridges to and from said magazines and visual and tactile monitoring of the number of said cartridges in box magazines which have been withdrawn from and inserted in a weapon. The device has a minimal weight and can easily be built into any box magazine of an automatic machine gun or a pistol having a spring-loaded cartridge feed mechanism.
1. A magazine device for universal charging and metering, the device comprising:
a housing;
a follower;
a follower spring having an upper spring end;
an intermediate support between said follower and said follower spring;
a cover;
a spring-elastic tie rod being constructed from one material of a group consisting of plastic, metal and composite and having an upper end and a lower end,
wherein said tie rod having a first face on a first side with a first numbered scale and a second face on a second side with a second numbered scale, said first numbered scale and said second numbered scale correspond to a number of cartridges,
wherein said upper end connects to at least one of a group consisting of said follower, said upper spring end, and said intermediate support, said upper end being located inside said housing,
wherein said lower end is comprised of a bend end formed by the tie rod folded back over itself so as to form a 180 degree bend in the tie rod;
a collar affixed around said bend end so as to define said 180 degree bend; and
a supporting ring passed through said 180 degree bend,
wherein said lower end passes through a hole in said cover, said collar and said support ring being outside said cover,
wherein the tie rod has a first position corresponding to said follower spring in a compressed condition and a second position corresponding to said follower spring in a tensioned condition, the tie rod being moveable between said first position and said second position according to said number of cartridges,
wherein said bend end is adjacent an end surface of said cover in said second position, and
wherein said cover has a plurality of protective protrusions around said hole, said protrusions extending outwardly of said end surface.
2. The magazine device for universal charging and metering, according to claim 1 , wherein said protective protrusions face each other across opposite sides of said hole.
3. A magazine device for universal charging and metering, the device comprising:
a housing;
a follower;
a follower spring having an upper spring end;
an intermediate support between said follower and said follower spring;
a cover;
a spring-elastic tie rod being constructed from one material of a group consisting of plastic, metal and composite and having an upper end and a lower end,
wherein said tie rod having a first face on a first side with a first scale and a second face on a second side with a second scale, said first scale and said second scale correspond to a number of cartridges,
wherein said upper end connects to at least one of a group consisting of said follower, said upper spring end, and said intermediate support, said upper end being located inside said housing,
wherein said lower end is comprised of a bend end formed by the tie rod folded back over itself so as to form a 180 degree bend in the tie rod;
a collar affixed around said bend end so as to define said 180 degree bend; and
a supporting ring passed through said 180 degree bend,
wherein said lower end passes through a hole in said cover, said collar and said support ring being outside said cover,
wherein the tie rod has a first position corresponding to said follower spring in a compressed condition and a second position corresponding to said follower spring in a tensioned condition, the tie rod being moveable between said first position and said second position according to said number of cartridges,
wherein said bend end is adjacent an end surface of said cover in said second position, and
wherein said cover has a plurality of protective protrusions around said hole, said protrusions extending outwardly of said end surface.
