Definitions

  • the present invention relates to a magazine for automatic firearms, in which the cartridges are accommodated in a cartridge belt.
  • a great variety of magazines for automatic firearms are known at present, such as box-type, segment type, drum-type and the like magazines.
  • a pre-stressed magazine spring or a mechanical impulse imparted by the firearm mechanism is used for feeding the cartridges to the cartridge chamber.
  • a revolving rifle magazine comprising a drum, carrying a starwheel with a blocking cog wheel, the teeth of the starwheel being adapted for engagement through mechanical means with a groove arranged in the breech cylinder and the blocking cog wheel being adapted for cooperation with a spring dog mounted in the casing of the revolving rifle magazine.
  • a disadvantage encountered in some of these magazines is the limited, relatively small number of cartridges, which can be accommodated in the magazine, as well as its relatively large dimensions, caused by the necessity of providing sufiicient space for the follower spring.
  • Other magazine types on account of their complexity, are not only expensive to produce but also highly vulnerable, as a slight damage or deformation of their working surface may impair the correct operation of the magazine.
  • the above-mentioned revolving rifle magazine is disadvantageous, as upon closing of the breech mechanism, the cartridge is only pushed nearer to the cartridge chamber and not until the breech mechanism is opened and retracted, is the cartridge brought into the feeding path under the action of the spring dog engaging said blocking cog wheel, so that the cartridge is not fed into the barrel until the breech mechanism is closed again.
  • magazines in which the cartridges are mounted in a cartridge belt for easier handling and maneuverability of the gun.
  • Such magazines may be of various design and usually are arranged so as to be fixed to the gun.
  • One design of such a magazine has a casing substantially of frusto-conical shape and the loaded cartridge belt is loosely placed in the interior of the magazine casing.
  • Another object of the invention is to provide a magazine for automatic firearms, in which the empty cartridge belt does not leave the magazine at all during normal operation of the gun.
  • a still further object of the invention is to provide a magazine for automatic firearms in which an ammunition space and an empty belt space of variable volume are provided, said empty belt space receiving the empty parts of the belt and increasing in volume at the same rate as the ammunition space diminishes due to the cartridges being withdrawn from the belt by the gun mechanism and the belt receding as a Whole towards the mouthpiece of the magazine.
  • a further object of the invention is to provide a magazine for automatic firearms which affords the gunner an instantaneous information about the number of unspent cartridges still available in the magazine.
  • the present invention provides a magazine containing two spaces of variable size, one of which holds the belted ammunition and the other receives the emptied cartridge belt, said two spaces being separated on the one hand by a fixed partition and on the other hand by a movable spring-loaded vane bearing in its operative position on the full cartridge belt and following its receding movement when being emptied by the gun mechanism, while the empty belt space increases.
  • the vane is preferably arranged as a radially extending rotary member which is rigidly connected to a control and indicator arm placed at the outside of the magazine and serving for shifting and fixing the vane in a position, in which the magazine can be charged with belted ammunition also for indicating the number of cartridges still available in the magazine.
  • FIGURE 4 shows an elevational rear view of the magazine
  • FIGURE is the corresponding sideview
  • FIGURE 6 is a cross-sectional view of the magazine.
  • the magazine comprises an open mouthpiece 1 consisting of two collapsible lids 2, 2' detachably secured to a magazine casing 3, which in the example illustrated in the drawings has the shape of a drum.
  • the attachment of the open mouthpiece 1 to the casing 3 can be accomplished by any known connection means, such as eyelets 4 and pins 5, 6.
  • a feeder 7 mounted for rotation in the open mouthpiece 1 of the magazine is a feeder 7 with two flanges 8, provided with teeth (not illustrated), seats (not illustrated) for the belted cartridges 11 being arranged between said teeth 9.
  • One end of the feeder 7 carries a ratchet wheel 12, which is subjected to the pressure of a spring 13, mounted on the shaft 14 of the feeder 7.
  • the opposite end of the feeder 7, outside the open mouthpiece 1, is rigidly coupled to a starwheel 15.
  • the breech 24 recoi-ls in the receiver 16, for example under the action of powder gases.
  • the helical groove 23 imparts a rocking motion to the rocker lever 18, which causes the starwheel 15 to turn along with the rigidly connected feeder 7 through one pitch of the cartridge belt 25.
  • the ratchet wheel 12 is rotated by one tooth, whereby the cartridge 11 is secured in its loading position, i.e. in alignment with the cartridge chamber of the barrel 27.
  • its front wall (not illustrated) pushes the next cartridge 11 from the cartridge belt 25 into the cartridge chamber 26 of the barrel 27.
  • the above described cycle is repeated.
  • the casing 3 is provided with a partition 28 positioned between the central shaft 29 of the casing 3 and the lids 2, 2'.
  • the central shaft 29 is mounted for rotation in two end walls 30, 31 of the casing 3 and is secured at one end against axial movement by suitable means, such as a lock-plate 32.
  • Fixed to the other end of the central shaft 29 outside the casing 3 is a control and indicator arm 33 carrying a button 34 having an opening 35.
  • An opening 36 is arranged in the end wall 30 of the casing 3, both openings 35 and 36 having the same diameter and being located at the same radial distance from the central shaft 29.
  • a radial vane 37 is rigidly mounted on the central shaft 29 and is biased by a spring 38 in relation to the partition 28 in a clockwise direction as viewed in FIG. 6.
  • the partition 28 and the radial vane 37 divide the interior of the casing 3 into an ammunition space 39 adapted to hold a full cartridge belt 25 and a space 40 for receiving the empty cartridge belt 41.
  • a scale 42 provided on the end wall 30 serves for indicating the number of cartridges 11 remaining in the magazine, which number is indicated by the control and indicator arm 33 travelling along the scale 42.
  • the pin 5 When charging the magazine, the pin 5 is first pulled out in order to release the lid 2, which is tilted away and the empty cartridge belt 41 is taken out from the space 40.
  • the control and indicator arm 33 and thereby also the radial vane 37 have to be turned in counterclockwise direction, as viewed in FIG. 6, against the pressure of the spring 38, so as to increase to the maximum the ammunition space 39, which is to receive the full cartridge belt 25.
  • the arm 33 can be secured in this position by the pin 5 fitted into the opening 35 of the button 36, which-in this positionis in register with the opening 36 provided in the end Wall 30 of the casing 3.
  • the magazine according to the invention offers numerous advantages over known arrangements. In the first place it is the reliability of its operation, due to the cartridge belt being placed inside the magazine and kept under permanent pressure in compacted conditions, so that its uncontrolled movement and entanglement of its links are prevented.
  • the emptied cartridge belt does not leave the gun, but remains in the magazine and is thus protected against soiling, damage or loss. The number of unspent rounds can easily be observed.
  • a considerable advantage is also to be seen in the fact, that the entire inner space of the magazine is permanently utilized for the accommodation of full and empty parts of the belt, which increases the economy of the whole arrangement.
  • a magazine for automatic firearms capable of storing belted ammunition and feeding it to the loading space of the firearm, comprising in combination:
  • feeding means operatively mounted in said magazine casing for feeding the belted ammunition to the open mouthpiece of the magazine
  • said fixed dividing member and movable dividing member dividing the interior of the magazine casing into an ammunition space and an empty belt space of variable sizes, the movable dividing member being adapted to bear forcibly on the belted ammunition in the ammunition space and to follow its receding movement towards the mouthpiece of the magazine.
  • said fixed dividing member is mounted on a central shaft mounted inside the magazine casing and extends from the central shaft to the feeding means
  • said movable dividing member comprising a movable vane mounted for rotary movement on the central shaft
  • said actuating means comprising a spring adapted to exert pressure on the radial vane to impart rotary movement thereto, said fixed dividing member and movable vane being adapted to divide the interior of the magazine casing into two spaces of variable volume, one of said two spaces serving for the accommodation of a loaded cartridge belt and the other for receiving the emptied cartridge belt, the radial vane bearing on the full cartridge belt and exerting pressure thereon in the direction towards the mouthpiece of the magazine.
