No. 531,990 Claims priority, application =Germany, Mar. 4, 1965, R 40,039 1 Claim, (Cl. i2-17) ABSTRACT 0F THE DSCLOSURE A cartridge feed for guns comprising a box-like vertical- 1y displaceable conveyer for the cartridge in the riile receiver. The conveyer is actuated by a lever mechanism which moves it upward from a normal position to a position in front of the ride barrel. The cartridge is guided by the receiver along both its longitudinal sides and at its rear end by a stop plate.

The invention relates to a cartridge feed in magazinefed rifles which permits the firing of a plurality of successively arranged cartridges in succession from a tubular magazine in a gun barrel, using a part controlled by a breech block.

According to the invention this is achieved by means of a cartridge feed which is characterized by a stop plate and side guide rails for guiding the cartridges on a vertically displaceable chamber-like magazine carrier, the forward end of which is disposed in the plane of the rear ends of the tubular magazine and the riile bore respectively and the carrying surface of which, corresponding to the length of the cartridge, is aligned either with the tubular magazine or the rifle bore in such a manner that the rearmost cartridge in the tubular magazine is pressed upon the carrier surface by spring force or is disposed in front of the riile bore in the cartridge chamber, a chamber lock with a pair of recesses disposed at different levels, the upper one of which serves to stop the tensioned chamber lock and the lower one to receive the return impact and a control part of the carrier actuated by an actuating lever guard.

A further embodiment of the invention comprises a two-arm lever mounted on a pin in the rilie stock, the forward, longer arm of which has a longitudinal slot for a claw provided in the carrier, the rearward shorter arm being positioned below, under the inuence of a leaf spring disposed in a chamber and arranged on the top of an angular lever with a guide head, said guide head being rotatable abouL a pin mounted in the rie stock, a further angular lever with a longitudinal slot being seated on said bolt, for securing to a linl'L and a lever whose guide pin extends into the longitudinal slot of the angular levers arm.

Particularly advantageous 1s the rounded portion of the release angle element extending into a corresponding recess, to assure a trouble-free stoppage of the bolt.

Furthermore, the guide rails extend to the level of the rie bore and abut the cartridges in the chamber with clamping action, resulting in a jam-proof transfer of the cartridges and preventing the cartridges from falling out.

Finally, the guide tracks are formed with a rounded recess at the level of the tubular magazine, corresponding to the outer diameter ofthe cartridge.

The invention is illustrated, schematically by way of example in the drawing, in which:

FIG. l is a partial section in the area of a magazine-fed rifle in unlocked condition;

FIG. 2 illustrates the breech of FIG. l, but in loaded condition and FIG. 3 is a cross-section taken on line Ill-III of FIG. l.

the breech of 3,387,398 Patented June 11, 1968 ICC The magazine-fed ride consists of a gun barrel 1 and a tubular magazine 2 for receiving cartridges 3, which are under spring tension, in known manner. The rear ends of the gun barrel and the magazine lie in the same plane. Back of these is the breech bolt 4 and receiver 5 and receiver lock 6, which is under the tension of a pressure spring (not shown) and is provided, forwardly, with a cartridge extractor. A conveyer 7 is disposed in the chamber, the forward end of the conveyer contacting the rear end of the tubular magazine and of the gun barrel, the cartridge bearing surface of the conveyer being displaceable vertically of the tubular magazine or of the gun barrel, the rear end of the conveyer abutting a stop plate 26 and its side cheeks being slidable between clamping guide bars 25. At the same time, the length of the conveyer or the distance between the stop plate 25 and the rear side of the gun barrel, corresponds to the length of the cartridge. The movement of the conveyer is etlected by means of a two-armed conveyer lever 8 which is mounted on a pin 9. The front lever arm has a longitudinal slit 10 into which extends a pin 11. The lower side of the rear arm is biased by a spring 12 mounted in the chamber 12a and is loaded to hold the conveyer in the position shown in FlG. l.

A release member 13 having a guide head 14 actuates the upper side of the rear of conveyer lever arm 8, said angular member being swingably mounted about pin 15 of the riile stock. Another angular lever arm 16 is further seated on the pin 15, and is provided with a longitudinal slot 17 and a pin 1S for controlling a link 19, which is provided on the pressure pin 20 of the release member 13.

The rifle stock is further provided with a pin 21 for the

lever

22, 23, both of which are integral. The lever has a guide pin 24, which extends into the longitudinal slot 17 of the angular lever arm 16. When the lever 22 moves into the position shown in FIG. 2, the cartridges on the conveyer 7 are moved by the

control parts

8, 13, 16, 19 in front of the gun barrel.

The breech bolt 4 has on its underside a pair of recesses 27 and 2S. A claw of the release angle 13 extends into the former whereby the receiver lock 6 is held in tensioned condition. Should the release member 13 be pressed downward by the movement of the

lever

22, 23 the receiver lock 5 is released, whereby the cartridge which is in rear of the gun barrel, is moved into the latter. At the same time the L-shaped lever 16 reaches into the second recess 28 and blocks the receiver lock 6 in a locked position.

It should be noted that the front lever of conveyer lever 8 is longer than the rear one and that the recess 27 is deeper to the right than to the left, when the conveyer 7 with the cartridge 3 thereon is already in front of the gun barrel.

Should the cartridges have been fired, the expended shell remaining in the riile is expelled by means of a claw from the barrel, the bolt is tensioned and stopped and the conveyer 7 moved downward. As it reaches its lowest position, the rearmost cartridge is pushed out of the tubular magazine and reaches the position shown in FlG. l.

rthe leaf spring 12, tensions the rear arm of the lever S, which presses the free end of the release angle 13 and thereby assures the stopping of the bolt.
