' MAGAZINE GUN WITH MANUAL RELoADING MECHANISM Frank T. Greenand Wilfred I. Smith, Haydenville, Mass.,

assignors to` Noble Manufacturing Co. Inc., Haydenville,` Mass., a corporation of Massachusetts fl Application June '728, 1957, Serial No. 668,719 1 claim. (ci. 42-11) This invention relates to a magazine type gun having manually-operated reloading mechanism.

It is the general object of the present invention to mprove and simplify the reloading mechanism, to provide additional safety devices and to make the reloading operation exceptionally certain and reliable.

An important feature of the invention relates to an additional safety device which prevents repeated operationof the gun without interposed release of the trigger. We also provide an improved frame and casing for the magazine and reloading mechanism, an improved cartridge ejector, and an improved cartridge transfer device.

Our invention further relates to arrangements and combinations of parts which will be hereinafter described and more particularly pointed out in the appended claims.

Referring to the drawings, we have shown our invention embodied in a shotgun having a barrel 40 (Fig. 2) fixed in the front end of a frame member 41 (Fig. 9) and having a magazine or storage tube 42 (Fig. 2) xed in a downward projection 43 (Fig. 9) of the frame member 41. The frame member 41 also has a rearward end portion 44 which is firmly seated in the usual butt 45.

A right side plate 47 (Fig. 10) is firmly secured to the right side of the frame member 41 and a left side plate 48 (Fig. 5) is firmly secured to the left side thereof. A trigger frame unit 49 (Fig. 4) completes the frame assembly. The right side plate 47 (Fig. 10) has a lug 47aA (Fig. 10a) yonits left side face, for a purpose to be described.

A breechbolt 50 (Fig. 16) is mounted to slide in a rearwardly Vand downwardly inclined direction in the magazine enclosure formed by the frame member 41, the right side plate 47 and the left side plate 48. The right side plate 47 is cut away at its upper right-hand portion as shown in Fig. 10 to provide clearance for ejection of the used cartridge shells.

The breechbolt 50 has the usual tiring-pin 52 associated with an anvil 53 and having the usual tiring-spring 54. A' hole in the upper part of the end portion 44 (Fig. 9) provides clearance for the tiring-pin anvil 53. A A yieldable shell-retaining spring 55 (Figs. 16 and 18) is mounted on the left side face of the breechbolt 50, and a pivoted hook lever or extractor 56 is mounted on the right side face of the bolt and is yieldingly pressed inward by a small coil spring 57. There is a downward lug or projection 58 on the lower face of the bolt for a purpose to be described.

A shell ejector 6i) (Figs. 2O and V21) is slidably mounted n the left side surface of the breechbolt and is retained in withdrawn or left-hand position by a small compression spring 61 (Fig. 16). When the bolt is moved to the extreme left for reloading the barrel, the ejector 60 strikes the end 44 of the frame member 41 and s moved relatively forward in the bolt to eject a used shell from the breechbolt.

' A cartridge transfer member 70 (Fig. 4) is pivoted at 71 to the trigger frame member 49 and has a notch 72 in its lower left-hand surface portion which is engaged by the offset end of a wire spring 73 which holds the member 70 yieldingly in raised position when shifted upward.

The member 70 has an arm 75 (Fig. 4) pivoted at 76 at the left-hand end of the arm and held yieldingly in raised position and against a stop 77 by a spring 78. second stop 47a (Figs. 10 and 10a) on the inside were@ ofthe rightv side cover plate 47 limits downward movementof the transfer lever.

The bolt 50 (Fig. 17) has notches 79 in its lower face which engage the upper corner of the arm 75 as the bolt is'- 'moved to theright in Fig. 4. This depressesthefarm 75 and swings the transfer member 70 upwardwitha freshvca-rtridge as the bolt 50 is movedtorward towards closed position. The forward movement cf'the-'car tridge -is facilitated by the lug 58 under the breech. 13C-,R50- ;.V r,

After the arm 75 engages the stop 77 (Fig. 4), the bolt slides freelyover the arm as' itcontinues its travel to'fclosed and locked-position. l Y

A hammer 80 (Fig. 22) is pivoted at Si'in the trigger frame unit 49 and has a shoulder'iSZ engaged by the free end of a sear 83 (Fig.v 26) which 'is adva-nced to engaging-.position by a searspring 83a (Fig.l 22)'. y

The scar is pivoted at S4 (Fig. -22)to th'eunit 49hand has an otfsetupward release'arm 85 (Fig. 26). The upper 'end of! the arm 65 is seatedv infra notch 87 (Fig. 25) in the upper face of a trigger link S'Snorrnallylraisedbyaspring 89 (Figs. 22, 3l and3la). 1 f l f The trigger 90 (Figs. 23 and 24) is pivoted-at 91 in the trigger unit 49 andvhas a'stud 92 (Fig. 24) lwhich seats in a notch 93 (Fig. 25) in the top edge ofthe link 88. A trigger spring 954' is shown in Fig. 22 and in detail in Figs. 30 and 30a.

The Vhammer has a slot in one edge which is traversed by a-p1in 81a (Fig. 13.) and on which is 'pivoted one end offarod 8 1b. Thisrvodextendsfreelythrough a hole ini-a ixed plate 81e. A spring 81d is mounte'd'on the rod 8119, wi'th one end of the spring abutting the 'plate 81CY and the other engaging a shoulder o-n the rodV 81b'. The spring activates the hammer when the hammer is released from the sear 83.

An olfset arm 95 (Fig. 23) on the trigger 90 is engaged by the lower end of a safety lock leyer'96 (Fig. 4) whenathersafety slide 97 is moved manually 'rearward to locking position. The slide is selectively retained" in either locking ornunlockinggposition bya suitallale'spring` (Fig. 4). l

A pump-bar 100 is slidable in a guideway 101 (Fig. in the left side plate 48 and has 'a lug 10.2;onits right side at the rear end thereof. cessed at 103 on its right side face and the recess extends to its forward end. The lug 102 onthepump-barseats inran angular recess 104 (Fig. 18)'inj the left 'side' face Yof the breechbolt 50 andeffects operation'ofthe bolt '5.0' by the pump-bar in the following manner: `The frame member 41 (Fig. 9) has a lower inner portion 41a with an inclined lower surface 41b anda righthand beveled shoulder 41e. Y

When the pump-bar moves the breechboltforwardly, the action of the lug 102 in the inclined slot'104 is lsuch as to press the breechbolt upward against the'sur'face 11b until the bolt passes the shoulderrl, which forms a bolt locking area thereafter receiving the ring pres-l sure. The lifting action is aided by the oifset angular contour of the slot 104 (Fig. 1S).

A cartridge retainer lever 105 (Fig. 5) is pivoted in a recess at 106 in the left sideplate 48. This lever has an offset 111g 107 at its forward end and an upwardly P'rQ- jecting carn lug 108 at the rearward 'end`thef1eofQ is also'a similar but reversed camlug 109-attheforwardk end.

As the pump-bar 100 is moved to the rear, the-rearward end of the bar 100 engages and depressies the earnl lug 108"on the lever 105 and raises the -`opposite cam lug 109 into the pump-bar recess 103, as shown in Fig.

2. The offset lug 107 (Fig. 12) is thusbrought up in'Y front of the new cartridge and holds back the next -cartridge inthe magazine tube 42. v Y

As the pump-bar is moved to the end of its forward stroke,y the full-height rear end portion 0f.he--pump bar engages and depresses vthe cam lug 109;;and moves-V the lug 107 below the path of the cartridge about to be-placed on the transfer lever 70. The depending lug 58 on the under surface of the breechbolt then engages the new cartridge and pushes it into the gun barrel 40.

An auxiliary safety lever 110 (Figs. 5, 11 and 14) is pivoted at 111 on the trigger frame 49 and assumes the position shown in Fig. 5 when the hammer 80 is cccked. This lever 110 Yhas a lateral locking lug'112 on its right side, an oifset downwardv handprelease 113 at its rear end, and an offset upward locking member 114 at its forwardendl' .1..

A spring 115 ,isA clamped bynotches y116 (Fig. 5) on the lever 110 and forwardly of the pivot 111. This spring 115 crosses over the top Vof the lever 110yand the frame 49 and ends in a downward bent hook 117 (Fig. 5) which is engaged by a stud 118 (Fig. 22) on the hammer 80.

Waen the hammer is cocked,ritk turns thelever 110 counter-clockwise in Fig. 22 but when the hammer is released, it turns thelever clockwise. In the clockwise po sition,` lthe forward locking member 114 on the lever 110 clears and releases thepurnp-bar 100, whichcan then be movedtov the rear, i.e.,'to-the leftin Fig. 5, withdrawing the boltlv50 and extracting the used shell from the'barrel.

When the hammer is thus released, the pump-bar can be operated, vbut ifthe hammer S0 is cockedl(Figs. 1 Aand 22),` the pump-,bar cannot be movedat'all unless the release 113 of the lever'110 is manually pushed up against thefpressureof the spring 115, wlliclrisV then tensioned bythe hammer stud 113.

The vauxiliary safety lever 110 vthus preventsaccidental movement of the pumnbar 100'or of the bolt` 50` while the hammer is cocked. Furthermore, the lug 112 of the lever 11.0 depresses the trigger link 88 (Figs. 13, 14 and 22) and thus prevents sear release of the trigger 90 until the rear end of the lever 110 is manually pushed up by release 113. Thisinsures single-shot operation.V

VShould the trigger be held Aback whilethe pump-bar is operated, Tnothing will happen, asjthe triggerlinkj88will notKY engage thesear untill the triggerf is released soy that th'etrigger link notch 87 can again engage the release -arm -of the sear $3.

Operation InFig. 1, the pump-bar is in full forward position, with the breechbolt in locked position, as bynsurface 41C ready to fire. The forward end of the cartridge retainer lever'105 hasbeenm'oved to its. lower position by the sliding movement of the pump-bar.

Fig; 5 shows the leftv side plate 484 with the pump-bar 100, the cartridge retainer lever v105'and the hammer safety. lever 1'10'in their respective working positions when the gun is ready to fire. Fig. 5 also clearly shows the forward end 114y of the safetylever 110 blockingjthe pur'npfbarI 100 from accidental backsliding or unlocking. If the rearward end of the safety ylever 110]'is now pushed up manually, the pump-bar canbe pushed tO the rear to the extreme dotted position in Fig. 5.` The rear end of the cartridge retainer lever 105 is thus pushed down bythe pump-bar, which has a clearance 103 to" receive the cam lug 109 vat the forward end of thercartridgeretainer lever 105.1 i

The .purnp-bar thusrocks the vcartridge Lretainerl lever 105 in and out of position to act as a stop for the cartridges fromvthe magazine, which cartridges can enter the loading area only at certain intervals in the cycle of loading andfunloading. i

If the breechboltV 50 fis pushedback by the pump-bar t o its extreme. rearward position, the back end of the ejector 60will hit thelbackfwall 44`of the frame 4112e-4 fore the bolt does, v and the front end of the ejector v will therebyeject the 'cartridge witl'rits beveled front edge which is shownin Fig. 2l. This rearward-fmotion ofl the bolt also cocks the' hammer and brings the sear into position to hold the hammer cocked;

When the bolt is at the extreme rear position and the fired cartridge has been ejected, the shell stop spur 107 of the lever 105 is in the upper or retaining position. If now the pump-bar is pushed forward with the bolt hugging the inclined top under surface 11b of the receiver frame 41, the transfer lever 70 will be lifted at its forward end (Fig. 2) by means of the little notches at 79 of the bolt 50 retaining the edge of the small secondary lever or arm 75 mounted on the transfer lever. This causes the transfer lever to lift the new cartridge into position for the bolt to get behind it and shove it forward into the barrel. The bolt then slides over the end of the arm 75 and holds the transfer lever in raised position.

After the secondary lever or arm 75 of the transfer lever 70 has been left behind by the forward movement of the bolt, the depending lug 58 on the forward under surface of the bolt 50 will engage the concave upper forward surface of the transfer lever 70 and will return the lever to its lower position. The cartridge stop or lug 107 (Fig. Vl2) on the cartridge retainer lever 105 is moved downward by engagement with the full-height rear end portion of the pump-bar, and this allows a new cartridge to enter the loading area.

The lug 58 has the important'additional function of stopping the next or entering shell after the cartridge retainer lever 105 has released the shell from the magazine tube. At this time, it is important that the next shell be prevented from moving completely back under the bolt, as this would prevent the gun being opened in the usual manner.

The lug 58 stops the shell, yet permits it to travel back with the bolt as the gun is opened, and to be ready to be lifted into position on the forward motion of the bolt.

A further forward movement of the pump-bar 100 will bring the bolt to the front edge of the main frame and into locking position. The safety lever 110 then snaps up behind the pump-bar to lock the same in place.

The usual safety catch prevents the trigger from releasing the hammer unless the catch is moved forward, which allows the trigger to push forward the link which swings the sear out of hammer-engagement, thereby allowing the hammer to give a sharp blow to the anvil on the firing pin and to cause the pin to indent the tiring cap on the shell.

The hammer safety lever 110 which is pushed down by 6 the pump-bar, when ejectingV and inserting a new cartridge, also pushes down the trigger link 88 and thereby directly prevents the release of the hammer by the sear during reloading. V

Even should the trigger be held in a pulled-back position while the pump-rod is moved to press down on the automatic safety lever, the trigger link cannot engage the sear or release the hammer.

Having thus described our invention and the advantages thereof, we do not wish to be limited to the details herein disclosed, otherwise than as set forth in the claim, but what we claim is:

In a magazine gun, loading apparatus comprisingan enclosing structure having a main frame, a separate and f removable left side plate, a separate and removable right side plate and a trigger frame, and means to secure said frames and plates to each otherV to constitute a unitary structure which provides a substantially enclosed loading area, said enclosing structure supporting loading mechanism mounted in said structure and secured thereto, a movable breech-bolt in the enclosure, a locking surface for said breech-bolt in breech closed condition thereof, said locking surface being on the main frame and located in position to be exposed from side-to-side upon removal of the side plates from the main frame, said locking surface being substantially rectangular and extending directly across the main frameV from side-to-side thereof.
