Definitions

  • This invention relates to automatically repeating fire-arms, more particularly of the double-' barrel type.
  • At least one of the twobarrels is longitudinally movable and so adapted, during its forward movement, to push a cartridge into the other barrel and fire/the same and, during its recoll, to eject the empty cartridge case from said other barrel while simultaneously loadingitself with a fresh cartridge.
  • the latte is fired when the barrelin-question reaches ,its
  • the forward motion loading barrel which is movable may be forced back by gases diverted from the other barrel, which is fixedly being brought forconsiderably more expen-. of fire-arms.
  • the forward motion loader barrel is v iorced back by the recoil ofthe other barrel and I rought forward again by a spring. It will. beclear that other types of actions are conceivable without departing from the main principle under-- lying the invention which may be summed up as. follows: Firing ofi one cartridge when'the first barrel is in the rearmost position,and firing ofithe next cartridge, through the second barrel,
  • the. stationary barrel may be utilized to guide the moving barrel, so that no guiding tube.
  • the moving barrel itself serves as gas piston.
  • this system may be adapted for alternate firing, both barrels, being equipped with rigid locking, and no controlling mechanism being required. On account oi the slight masses to be accelerated, this system develops a very high rate of firing, and combines simplicity of construction which rigid with light weight. It is also possible to do without the breech'either for the movable or the stationary barrel, or for both, in cases in locking of the barrels is not necessary. f
  • Fig. 1 is a side elevation, partly in loiigitudinal section-Fig. 2 is of a form of construction according to the present invention'includinga cartridge magazine feed; a section taken on the line H of Fig. 1.
  • the phase 'shown in these two figures is the forward position of the movable barrel.
  • Fig. 3 shows a form of construction for use with a double-row cartridge belt
  • Fig. 4 is a side elevavtion on the line b-b of Fig. 3
  • Fig. 5 a section taken on the line H of Fig. 3, the breech 01' the moving barrel being removed for the sake of clarity.
  • J Figs. 6 to 11 show a further form of construc-- tion inwhich the ejector serves at the same time for the forward feeding of the cartridge carrier.-
  • the barrel- 3- is I and provided, near the muzzle, with thejgas chamber So,
  • the moving barrel 2 is guided in] this chamber-'and in the housing- I.
  • this barrel is equipped with the annular gas piston 20 and at its. rearward part with a long'extension 2a to which there isattached the pusher rib is (Fig. 2) together with the eiector rigidly mounted in the housing the breech block 5.
  • the latter is capable of iongitudinal movement, and, in its foremost posi-' tion, of a slight pivotal movement to which it is constrained by the engagement of the claw 5k. in suitably shaped grooves in the housing I.
  • the striking pint is. adapted to lock itself-to the barrel extension 2a.
  • the firearm is in the position in which the moving barrel 2 is at back dead centre.
  • the top breech block is then connected and locked to its barreLsince the claw 5k depresses the rear end of the breech.
  • the barrel 2 will then not be loaded.
  • the lower breech 9 is thus likewise in its rearmost position.
  • the closing'spri ng 4- draws it forward taking the upper breech along with it until this breech is unlocked by engagement of the claw 5k in the casing, and comes to a standstill.
  • the barrel 2 travels on, and its pusher rib 2e engages the rear end of a cartridge from the magazine, in known manner, and carries it along in front of it.
  • the two barrels may be disposed very closely together, and in this manner it becomes possible to combine the two magazines in a single unit. The changing of magazines is thereby greatly facilitated.
  • the cartridges may also be fed with the aid of belts or metal bands.
  • belts or metal bands In order to avoid the necessity for using two separate belts there may be used either an ordinary single-row belt with dual-stage feeding through the fire-arm or a tworow belt with single-stage feeding.
  • Each magazine consists of the box, Ill, the feed piece .21s, these latter elements being adapted in part ance with the invention using a two-row cartridge belt is shown in Figs. 3 to 5 of the drawings.
  • each pair of cartridges is disposed, one behind the other, in a semi-cylindrical element of the chain or belt 26 and held therein by means of spring clips 26k.
  • the individual elements of the carrier are articulately connected together by means of pins 21.
  • the bent-up tongues 262 prevent the cartridges in row 11 from touching with their tips the cases of the cartridges in row I.
  • the apertures 28 in the elements of the cartridge carrier allow the This latter is pivoted about the axis l8 and has mounted upon the axle IS the pawl l5, both being pressed upon by a spring IS.
  • the chain of cartridges travels in a passageway provided in the housing I, and is prevented from slipping back by the ratchet pawl25.
  • the feed movement is imparted by a sliding member 20 which is mounted in the housing slidable in a direction at right angles to the axis of the barrel. Mid-way in its length this member is provided with a stud 20z which engages in the groove 2n in the barrel extension 2a At the lower end the 1 feed pawl 2
  • the restoring spring 4 presses against the barrel extension 2a in the bore'of which it is guided.
  • the barrel extension is equipped withthe pusher rib 2e with the nose 2a and the ejector 210.
  • the moving mechanism and the breech mechanism correspond to the sameparts in the form of construction shown in Figs. 1 and 2. Behind the breech.5 there is provided in the present form of construction a buffer with a bufier spring l4.
  • the breech block 5 is unlocked and fixed
  • the stud 2llz'on the sliding member is guided by the groove 211, with the result that the feed latch 2
  • the ratchet pawl 25 prevents the cartridge carrier from slipping back.
  • the barrel becomes locked tmthe breech block 5, and the striking pin 6 encounters the buffer 13 and fires off the cartridge.
  • the barrel 2 slides considerable simplificationf of the design as a whole 'is rendered possible.
  • Figs. 6 to 11'of the drawings show a form of' Broadly, this result is achieved in accordance with the invention by providing, for the purpose of feeding the cartridge carrier forward; a preferably pivoted member which is movable in one plane and also transversely thereto, the movement ofiwhich member may also be utilized for setting or"a d,iusting the cartridge in the proper loading position.
  • An advantage of this arrangementaccording to the invention thus resides in the fact that the said member is capable of effectveyor shoe or the like can be dispensed with.
  • this latch element may be. arranged to remain within the cartridge carrier throughout the entire feed cycle without causing any trouble.
  • this construction makes it possible to dispense with all pawls and moving axles, so that the member provided for effecting the feeding forwardahd the actual positioning of the cartridge may be formed by'a single sturdy and resistant part q fi the-fire-arm.
  • FIG. G being an inverted plan view of the conveyor feeder, the cartridgecarrier being omitted for the sake of clarity, and Fig. 7 a section on the lined-a of Fig. 6.
  • Fig. 8 is a separate elevation of the feeding and positioning member proper, as seen from beneath, and Fig. 9 an enlarged section on the line d-d of Fig. 8.
  • Fig. 10 is a sectionon an enlarged scale taken thr'oughthe central bearing of the'feed member, and'Fig. 11 an inverted plan view of the. central bearing shown extension 32. 33 denotes the.
  • This member 33 is rotatably and pivotally mounted in the housing 3t, for which 'purposeit is fitted on a pivot pin 35a on the housing 34- (Fig'. 7) and guided with its transverse arms 33qu in arcuate grooves 36! in the housing. manner of support enables the member 33 in the first place to carry out a rotary movement through the angle 3, corresponding to the feed movement of the cartridge rrier 31.
  • the member 33 thus can movefreely in two directions. Twisting moments in the' third plane at right angles to the direction of the barrel are taken up by the two transverse arms.
  • a feed catch 338 likewise provided on the member 33 extends, in the position of rest, into a-cam groove in the barrel extension 32. This groove is partly in the form of a through slot, the remainder being shallower.
  • the shoulder 22 of the groove serves for the posi- .tioning movement. while the part s of the groove serves for the forward feeding movement. At h the deeply excavated part begins. again, and at r the cam groovefor the restoring movement.
  • the assembling oi' the'aborve described parts I is simple: a member as is placed in a position 9 tion in firing.
  • the cam groove may be provided in any part which travels through a sufficient distance in the course of the loading movement, I
  • Figs. 1 and 2 show a form of construction of this type.
  • Figs. 3 to 5 show a different type in which the cartridge in the moving barrel is fired off before the rearmost position is attained, by impact against a yielding buffer.
  • the recoil at once set up accelerates the backward movement of the barrel, and this very considerably increased recoil energy is stored up in the very powerful buffer spring which, as far as possible, should be of nondamping character.
  • the spring buffer imparts to the barrel an extremely powerful initial urge forward to which there is added, as in the previous form of construction, the action of the restoring spring.
  • the recoil energy of the barrel 2 is thus made use of to accelerate the forward movement. This results in a very considerable reduction in the time required for the forward movement, and with it an increase in the rate of firing. It will be clear that the firing operation may be effected in any other suitable manner before attainment of the rearmost position of the moving barrel.
