Abstract

Abstract An automatic weapon equipped with at least two cartridge magazines from which loose cartridges can be conveyed into a common discharge channel, and a device for switching the cartridge infeed from one cartridge magazine to the other. The switching device embodies mechanism which can be selectively adjusted into two positions independent of emptying of one of the cartridge magazines. By means of the mechanism the cartridges in each instance can be fed, in one position of the mechanism, from the one cartridge magazine into the discharge channel and at the same time are blocked in the other cartridge magazine.

Claim 1
Independent Claim 143 words
An automatic firing weapon comprising at least two cartridge magazines, a common discharge channel, said two cartridge magazines containing loose cartridges for conveyance into the common discharge channel, means for switching the delivery of cartridges from one cartridge magazine to the other cartridge magazine, said switching means comprising mechanism selectively adjustable into two positions independent of the emptying of one of the cartridge magazines, said mechanism in one position feeding the cartridges out of one cartridge magazine into the discharge channel and at the same time blocking the cartridges in the other cartridge magazine, a switching wheel located in the discharge channel, a hydraulic-mechanical feed device for delivering the loose cartridges from the cartridge magazine opened by said adjustable mechanism to said switching wheel, said switching wheel bringing the cartridges into a central position substantially coaxial with the lengthwise axis of the weapon.
Claim 2
Dependent Claim 143 words
An automatic firing weapon comprising at least two cartridge magazines, a common discharge channel, said two cartridge magazines containing loose cartridges for conveyance into the common discharge channel, means for switching the delivery of cartridges from one cartridge magazine to the other cartridge magazine, said switching means comprising mechanism selectively adjustable into two positions independent of the emptying of one of the cartridge magazines, said mechanism in one position feeding the cartridges out of one cartridge magazine into the discharge channel and at the same time blocking the cartridges in the other cartridge magazine, a switching wheel located in the discharge channel, a hydraulic-mechanical feed device for delivering the loose cartridges from the cartridge magazine opened by said adjustable mechanism to said switching wheel, said switching wheel bringing the cartridges into a central position substantially coaxial with the lengthwise axis of the weapon.
Claim 3
Dependent Claim 73 words
The automatic firing weapon as defined in claim 1, wherein two respective cartridge magazines are located to each side of the lengthwise axis of the weapon, a respective one of said adjustable mechanisms arranged to each side of the lengthwise axis of the weapon, means for operating said actuatable mechanisms independently of one another, and a respective one of said switching wheels provided to each side of the lengthwise axis of the weapon.
Claim 4
Dependent Claim 159 words
An automatic firing weapon comprising at least two cartridge magazines, a common discharge channel, said two cartridge magazines containing loose cartridges for conveyance into the common discharge channel, means for switching the delivery of cartridges from one cartridge magazine to the other cartridge magazine, said switching means comprising mechanism selectively adjustable into two positions independent of the emptying of one of the cartridge magazines, said mechanism in one position feeding the cartridges out of one cartridge magazine into the discharge channel and at the same time blocking the cartridges in the other cartridge magazine, the adjustable mechanism comprises a slide member selectively displaceable into two positions, two spring-loaded guide portions hingedly connected with said slide member, said slide member when in one of its positions deflecting the cartridges by means of one guide portion out of the one cartridge magazine into the discharge channel and the cartridges in the other cartridge magazine being blocked by the other guide portion.
