Yaia- 7126) (Granted under Title 35, U.S. Code (1952) ,'sec. 266) The invention described herein may beemanufa'ctured and used by orfor the "Goverment fr"governmental purposes without the payment of any royalty thereon.
This invention relates to multi-barrel iirearmsof the type generally fired from the shoulder of the user-and more particularly to means for continuously feeding ammunition thereto. In modern-day lirearms the ydemand for firepower and accuracy are the dominating factors to be considered in the final design thereof. Present automatic rifles or lightv machine guns fulfill the firepowerV requirementsgbutfall short when it comes to accuracy.' This'isd'u'e 'to the" lAccordingly, the development'- ofi .a semiautomatic,`
multi-barrel shoulder weapon would-'seem to provide the required firepower and yaccuracy'in that'a plurality of projectiles may be discharged with each :pull ofthe trigger, thereby allowing each successive shot to be aimed by the operator insuring greater accuracy while the firepower is governed only by the rapidity with which the lirear'm can be aimed and the trigger pulled.
However, extensive use of the shoulder type of multibarrel firearms has heretofore been limited by the diiiiculties involved in continuously feeding' ammunition thereto. Many systems exist for feeding these firearms but they all require `special means for handling the cartridges in the :gun prior to being chambered in the barrels, or special chambering is required as the'cartridges aregenerally inclosed in clips and are chamberedand fired while still retained initsuch clips. `Also, specials means must be provided for ejeting the empty clips from the gun.
It is, therefore, an object of this invention to provide.
a multi-barrel shoulder iirearm with a simple,vdurable,
yet inexpensive feeding system whereby the simultaneous chambering of a plurality of cartridges may-be accomplished with a minimum of handling.
Another object ofmy invention is to provide such firearm with an integral openv end magazine such that cartridges can be readilyA loaded therein from. the bottom without requiringmanual*y operation of the charging mechanism.
A further object vof invention is to provide suitable which the magazine-caribe loadedQ contact with the bolt assembly to the magazine into the firearm, p
It is a further object of my inventionto utilize the lift'the cartridgesfrom recoil energy ofthe-bolt assembly not onlypto extract and eject the lirecartridge cases but also, simultaneously therewith, to strip. theempty cartridge clip" from the to of the magazine and eject it from the firearm. i), in,Y some multi-barrel-,firearms of-.the shou1de1j.type

Referring now to the drawings and in particular to Figs. 1 and 2, there is shown a firearm having a receiver 12 in the forward end of which is l'securely mounted a plurality of barrels 14 having tiring chambers 15. it will be noted that while three barrels are shown in the present embodiment, the number is not limited thereto since'more or less could be fed in the same manner as that described hereafter. The rear end of receiver.
12V terminatesin a cylindrical stock 16.
Provided'in the underside of receiver 12 and integral therewith, is a cartridge magazine 18 having its free end open, as shown at 20, for a purpose to be described later. A substantially rectangular port 22 is formed in the side of receiver 12 and is located above the upper end of magazine 18 in position to direct the fired cartridge cases out of receiver 12.
Reciprocably mounted between barrels 14 for longitudinal movement in 'response to the discharge gases generated by the ring of, cartridges 24 is a conventional operating rod 26 having acharging lever 28 for permitting manual operation thereof.
A bolt assembly 30 is Slidably mounted in Aopposing grooves 32 in the sides of receiver 12 for reciprocation between battery and recoil positions. Bolt assembly 30 includes a carrier 34 and a plurality of cylindrical bolts 35 slidably disposed therein corresponding to the num- -ber of barrels 14 and in respective axial alignment therewith. Extending rearwardly from carrier 34 cylindrical guide rod.36-which. supports the forward portion of a surrounding recoilspring 38 seated against the rear of carrier 34 to normally bias bolt assembly 30 to the battery position. The opposite end of recoil spring 38 extends beyond guide rod 36 into a bore 40 formed into stock 16. A longitudinal rib 42 is formed on either side of the carrier 34 for sliding engagement with grooves 32 of receiver 12. Ribs 42 project rearwardly of carrier 34 and are each provided witha depressor 44 depending from the rear end thereof.
As best shown in Fig. l, depressors 44 are of suicient length to effect respective slidable contact of the bottom surfaces thereof with the upper surfaces of a spacedapart pair of followers 46 Slidably disposed in magazine 18. The forward edges of depressors 44 are angularly formed, as at 50, for a purpose to be subsequently shown and extend upwardly and forwardly to terminate slightly forwardly of the rear end of bolt carrier 34.
Each depressor 44 is also provided with an integral, forwardly extending arm portion 54 disposed on either side of carrier 34. Arm portion 54 of each depressor 44 is spaced below the underside of rib 42 to form a longitudinal opening 56 therebetween and, consequently, depressors 44 are connected to ribs 42 only by a web portion 57.
'I'he interior side wall surfaces of receiver 12 immediately above magazine 18 are provided with opposing inwardly directed rectangular ledges 58 provided with an angular stop surface 59 along the underside of the rear ends thereof. Ledges 58 are disposed so as to lie between the underside of carrier 34 and the top of depressor arms 54 when bolt assembly 30 is in the battery position as shown in Figs. 4 and 6. A V-slot 60 extends longitudinally along the upper surface of each of depresser arms 54 and is varranged to engage the top one of isav af stack of clips 62-in a manner to be described hereina ter.
cated at the top of cartridge retaining portion 901mmediately above leg portions'92 are a pair of integral downwardly angled tabs 96 arranged to be releasably engaged by hooks 94 of the next successive 'clip thereabove. The distance between the free ends of leg portions 92 is slightly less than the interior transverse dmension of magazine well 64 to allow hooks 94 to snap over tabs 96 as the clips are fed into magazine 18-`from the bottom thereof to form a vertical stack. As the stack of clips 62 is lifted by followers 46 into receiver 12, the tabs 96 of the uppermost clip engage the corresponding angular stop portions 59 on the underside-of ledges 58. As bolt assembly 30 starts its counterreooil stroke and depressor arms S4 pass over the top clip 62, tabs 96 Slidably engage in the V-slot 60 in arms 54, thereby supporting the stack of clips 62 as followers 46 are cammed downwardly by angular surface 50 on depressors 44 as bestv shown in Fig. 3.
As best shown in Figsg2, V3 land 12, the forward end of cartridge retaining portion 90 of each clip 62 is cut away as indicated at 98-to,form averticalV shoulder 100. A pair of substantiallyv S-shaped catches 102 -are pivotally mounted by a pin 106 in a rectangular recess 104 vextending transversely throughY depressor arms 54. A at spring 108 is xedly mounted in each, arm 54 by suitable means and normally biases catch. 102 into the position shown in. Eig. 8 for releasable engagement with.
shoulder of clipl 62 forV stripping the empty clip from` the top of the stack in` magazine 1.8 andvejecting it through a port 110 provided in the bottom'of .receiver 12 rearwardly of magazine 18. f Y f Immediately beneath receiverledges 58 and adjacent depressor arms 54; when bolt `assembly 3l)l is in the battery position, is a longitudinal undercut 112 in receiver 12 to allow catches102 to be pivoted into engage'V During the counterrecoil movementof `bolt'assembly 30, bolts feed the cartridges 24 in the'l top'clip 62 forwardly into the respective chambers 15` of barrels 14.
Since the force of this stripping action has a' tendency to simultaneously move top clip 62 forward-,ra shoulder F118 Y. is provided on each of theledges 58 immediately forwardA of angular stop portions 59 thereon to cvc'mta'ct''theV forward edge of tabs 96 and thereby prevent Yzany' `forward movement of clip 62. The arrangement o'fstop portions 59 and shoulders 118 is clearly shown in'I-ig. 7.
.Operation In preparing the gun for the feld,"clps :62 loaded` with cartridges 24 are inserted into the bottom of 'magazine well 64 one or more at a' time. -It willV be noted that while inserting clips 62 into magazine well 64,- latches 86 are cammed out of the way by clips' 62. Likewise, lifter 4A'the end ofjits recoil stroke, again starts forward under As the bolt assembly 130 starts to recoil in response to the discharge of the cartridges 24 in barrels` 14, springs ftlSfbias catches. 102'ondepressor arms 54 to contact? shoulder 100 of the 'lr'lppermostllv clip 62 thereby pushingthe` clip to therear, whereby hooks 94`a`re slida'bly released from tabs`-96fff the next clip 62 therebeneath,v
During therecoiltravel of clip 62, catches 102 engage cams-i114 of --undrcut' portions 112 andare forced out of contact with shoulders 1100. However, clip 62 continuesto recoil together'witl-f'carrier 34 since Atabs 96 are positioned in V-slots 60 on depressor arms 54.v WhenboltV assembly 30 Yrecoils to a point'where the'femptyclipl 62/V is directly o'ver port 110 in receiver 12, the rear edge off' the cartridge retaining'portion 9 0 engages'lug 116,'jthus,

When bolt assembly 30 isv in lthe closed or battery position, depressors `44 forceY followers 46 downwardly. As the last clip 6 2 is inserted into magazine 18, the cartridges 2 4Iin lthe uppermost' clip will contact the underside of carrier 34. At such time, pressure applied to the bottomV 'clip of the stac'klw'illl causeV thel hooks 94 of' leg portions 92 to snap over tabs9v6'on ,the adjacent clips, thereby connecting all of thefclips into a vertical stack. At least two of the clips 62`willT-lie yabove lifter members 80 in followers- 46 although not in position to be supported thereby as shownjin Fig; 4. Once the stack of clips 62 is formed, it is retained in magazine 18 by latches 86.
As bolt assembly 30 moves forwardly and the cartridges are stripped from the uppermost clip 62, V-slot 69 in depressor arms 54 slidingly engages tabs 96 on the uppermost clip 62, thereby supporting the stack of interconnected clips as the angular surface 50 of depressors 44 cams the followers 46 downwardly against the bias of the follower springs 72. At the same time, the forward edge of tabs 96 contact shoulders 118, thereby holding the clip 62 against forward movement. When bolt assembly 30 has reached the battery position, depressors 44 have positioned followers 46 so that lifter members 80 will this time engage the leg portions 92 of the second loaded clip of cartridges in the magazine 18 as best tion whereuponthe firing cycle is then repeated.
.fisV mentioned here'tofore, the Ymagazine is openat its? freeend thereby permitting ythe 'rapid loading `oflclips` of cartridges into the-magazine at anyconvenientv time during theoperationiof the firearm "without having to stop Yand handoperatel the mechanism 'as is 'necessary' i' with many of the firearms currently vin use.
