  • DOUBLE-BARRELED AUTOMTIC GUN May 30, 1950 Filed sept. Yles, 1947 Q Q HHH UJT f Y www f u m P uw. 1
  • This invention relates to automatic guns and is applicable inter alia to automatic guns of the barrel individually experiences a rate of re which is half that of the gun.
  • each breech block in the ring position is obtained with the aid of a lever that can swing from a position where it locks one breech block, to a position where it locks the other breech block.
  • the swinging movement of said lever can be brought about by the recoil and run-out of the breech block which is not locked thereby, so that on completion of the run-out of the unlocked breech block, the.
  • level1 completes a swinging movement whereby it locks the hitherto unlocked breech bioch and releases the other for recoil and run-out in continuation of the cyclic locking action oi the lever.
  • Figure l is a plan View of a machine gun from which the cartridge feed mechanism and other parts have been removed, to show the breech mechanism in detail
  • Figure 2 is a longitudinal section taken on the line II-II of Figure 1, as seen in the direction of the arrows shown in Figure 1,
  • Figure 3 is a section on the line III-III of Figure 2', as seen in the direction of the arrows,
  • Figure 4 is a plan similar to Figure l but showing a different operative position of the breech mechanism
  • Figure 5 is a skeleton plan similar to Figure 4 but showing a further operative position of the mechanism
  • Figure 6 is an underneath plan of the breech mechanism showing a detail of the mechanism thereof.
  • Figure '7 is a plan of the breech. end oi the gun, showing the feed mechanism thereof.
  • the gun has a breech casing including a bottom plate l and side plates 2.
  • the breech blocks are of similar construction and are both adapted to slide longitudinally within the breech casing.
  • the side plates i! are grooved and permit hand cooking handles l and 8 to protrude therethrough.
  • Each cooking handle is elTectively integral with its associated breech blocks, and light recoil springs 9 and It serve to hold the breech blocks in their forward position illustrated in Figure l.
  • the base plate l of the breech casing ' carries a stud Il upon which is pivotally supported a lever l2.
  • the latter can Swing upon its pivotal support, the free end being tapered as seen in plan so as to be engageable with either breech block 5 or 6.
  • the stud ii' is supported indirectly by a vertical lug l lA which forms a seating for the boss of the lever l2.
  • each breech block has a cut away portion leaving a rearwardly extending part i3, i4 and a transversely ei:- tending part l5, IS.
  • the free end of the lever l2 is showing engaging behind the transverse part i5 of the breech block 5'.
  • the free end of the lever l2 has a downward extension il' acting as 'a iinger for engagement in an arcuate slot i8, provided in the base plate member l.
  • the arcuate slot i8 is, of course, centred about the pivot vII of the lever l2, so that the lever can freely move about its pivot.
  • Each transverse part I5 and 4I5 of the breech blocks has a firing pin (not shown) located therein, the ring pins being operable by mechanism located in the free end of the lever I2, as at l'9.
  • a protruding head 2U is arranged so that when the head is depressed 'with the lever l2 in the positionvshown in . Figure 1, the firing pin of the breech block 5 is brought into operation. It will be comprehended that whenk'the lever l2 is swung to the opposite position where it engages the breech block 6, depresssion of the head 20 will then result in the operation oi the ring pin associated with the breech block 6.'
  • the underside of the lever l2 has an island cam 2l for engagement with a cam pintle 22', It will be observed from Figure 1 that the island cam 2l is triangular in shape with the apex of the triangle directed towards the pivotal Asupport of the lever I2.
  • the upper end i23 of the cam pintle 22 is also of generally4 triangular shape as seen in plan, the apex being, however, directed oppositely in regard to the apenv of the island cam 2
  • the pintle 22 passes through the base niember I of the breech casing and has a plate 24 secured to it.
  • the underneath plan view in Figure 6, shows the plate 24 and it will be observed that it possesses a biiurcated end 25 permitting the plate to be displaced to a position where the bifurcated end lies around an anchor post 25.
  • the latter is pivotally carried in the base member I' and grips one end of a rod 2 the other end of which passes freely through the lower end of the cam pintle 22.
  • a spring 28A is located over the rod 21 and tends to urge the pintle forwardly together with its plate 24 (the direction forwardly refers to the direction towards the right in Fig. 2 i. e. from the rear of the gun towards the barrels thereof).
  • the plate 24 can both slide and also move angularly about the anchor pivot 25, and is guided in suitably formed facing grooves in two strips 23 and 2e secured to the underside of the base member l (see Fig. 6)
  • a hammer bar 35 lies transversely within the breech casing and is guided in a recess 3
  • has two curvilinear sides 32 and 33 which permit the hammer bar 3B to be swung about either end towards a position where it lies more nearly along the axis of the gun.
  • the thin platform produced by provision of the recess 3l, is cut away to form a slot 34 through which the cam pintle A22 projects.
  • the slot 34 is of approximately triangular shape, the base being however, curvilinear in general continuation of the curvilinear sides 32 and 33 of the recess 3l.
  • the apex of the triangular slot 34 finishes in a short straight slot 34A dimensioned so that the cam pintle 22 can t therein.
  • a double gas-block 40 is provided, each individual gasblock communicating with the'interior of one of the barrels 3 and 4 of the gun.
  • the double block houses two gas pistons 4I and 42 which both bear against the end of a rod 43.
  • the latter is provided with a roller 44 which engages a transverse bar 45 havinga pin 45 which may enter a slot 4l.
  • Each end of the bar 45 - is formed with a nose 48 located in an associated slide block 49.
  • the forward end of each breech block 5 and 5 bears against the rearward end of one of the slide blocks 49.
  • the springs 9 and I0 associated with the Ybreech blocks will serve to keep the bar 43 in contact with the gas pistons 4l, since both such springs urge their breech blocks forwardly and hence correspondingly influence the slide blocks 49.
  • the recess 55 can be engaged over the sear 5I Vin the manner shown in Figure 4.
  • the breech block 5 will be retained in this position by the sear against the action of the spring 9 which is now extended.
  • the transverse part I5 thereof encounters the bar 3i). It causes the bar 30 to be swung around one end until it reaches the position shown in Figure 4. Movement towards this position of the bar 3D, causes the latter to encounter the campintle 22, the upper end 23 of which rides along the adjacent side of the island cam 2l.
  • the cam pintle 22 is ⁇ carried backwardly against the action of its spring 28A.
  • the usual pawl 62 for preventing reverse feed may also be provided (see Fig. 3).
  • the slide 5l is moved transversely across the breech. mechanism by a lever 63 pivotecl intermediate its ends in the breech casing (see Figs. 2 and 7).
  • the lever t3 is engaged by an arm Se of a bell-crank, the other arm S5 of which engages a pin 6B that may conveniently be the pin upon which the roller 44 is mounted.
  • the ammunition belt is advanced by a distance equal to the space between the rounds carried in the belt. It will be noted from Figure 3 that the distance between the axes of the rounds is equal to half the distance between the axes of the barrels of the gun. Since the belt traverses only the distance between the rounds on each complete reciprocation of the feed slide l, it will be clear that there will always be a round ready for extraction from the belt to produce an appropriate feed to the barrel that is to fire.
  • Pivoted or retractable feed-pieces 'lll of any well-known type are carried upon each breech block and serve to bring a round into the firing position as the breech block moves forward on the run-out.
  • the used cartridge case is withdrawn from the chamber in the usual manner, and can be ejected through ejection apertures 'il provided in the base member of the breech casing It may be found desirable in practice to cushion the last part of the recoil of each breech block.
  • stops 80 which operate against springs 8l enclosed in a suitable casing at the rear end of the breech mechanism.
  • each breech block ior iiring the barrel whose breech is ocked in the iiring position means responsive to the ring of a barrel to produce a force tending to cause recoil of both locked and unlocked breech blocks with respect to their barrels,
  • a double-barrelled automatic gun for ⁇ alternate firing from each barrel comprising a reech block for each barrel, slideways allowing each said breech block to slide relative to the associated barrel towards and away from the firing position, a lever, a pivotal anchorage for said lever at one end thereof to permit the other free end of said lever to be swingable between two positions, a locking face upon each breech block against which said other free end of said lever can engage and lock when the breech block is in the ring position, firing means for firing the barrel whose breech is locked in the firing positionV by said lever, means responsive to the firing of a barrel to produce a force tending to cause recoil of both the locked and unlocked breech blocks with respect to their barrels, such force being effective only upon the unlocked block, and means associated with each block for displacing said lever on the run-out of the unlocked block to cause said lever to be displaced to engage the locking face of the running-out block in the firing position thereof.
