To aZZwLo/m it'mafy concern:

Beit known that I, J oH-N D. FEDERSEN, of-A Jackson, in the-.Country ofUinta and State-of Wyoming, have invented:` certa-in new andnseful Improvements in Cartridge-Stops for Magazine-Firearms; and Ii (io-hereby declare that the following-is a full', clear, and exact description thereof, which will enable others skilled in the' art to which it appertains to make 'and use-the same, reference being had to the accompanying drawings, andi to the characters of reference marked thereon, which formpartof this specification.

The object of my present invention is to provide a cartridge stop for the magazinel of a re arm,.which is particularly adapted for use with fire arms having reciprocating magazine action-bars, andi which, coperath' nig with the other magazine at times, rpre vents the. escape of t-he cartridge from the magazine, and at Others spaces and controls magazine.

Referring' toy the reference' letters and' 1909. Serial No. 48B35 figures in a more particular description, w indicates themam portion of the frame having: the barrel 16'securedto the forward' end'.`

The other portion` of the frame 17, usually known as va trigger plate, isy preferably detachable from the part 1'5' and' has. secured to its rear end the butt stock' 1 8` and carries 'shoulders' at 21. For operating the breech block; 20 it is provided with a pair of iricli'ned tooth-like projections 20 adapted' t0 engage with the rear end' of the ma azi'ne action bar* 22,. and' particuiarly Wi the angular notch 23 inthe'rear end of" the action bar. The action bar 22,-passes through an openin at 244 in the forward' endi of the frame anl is adaptedto, reciprocate fr- Wardly and. baekward'ly lin said' opening,V whichv serves as a bearing or support forl the rear end of the action bar.- The forward portion of the action har which lies under the barrel may be pnovided with a sldlng handle secured thereto in the usuah .maar ner. TheY action bar'is provided* longitudi- 11311) W'tl'r a tubular magazine 25', which preferably' receivesl an' inner tuhe 26. andx a spring actuatedi follower' 27. The rear end" of the magazine termi'natesat the shoulder 28, and thev rear end of the action bar, 1ncludingthe r'magazine tube, is; verttloallr sl'ottedas indicated at 29;, said slotcreceivinginpart ythe cartridge sto 305' and 111 part providing` a space. iIr whiic 'the cartrldge, carrier 31. is adapted to'. operate. .Alt the rear endI of1 the tubular magazine, the top of the action bar is out away to a1fordfa cartridgeoutlet openingtransversete the length' of-` said; action: har. vThe general` .width of thisopenngfiis such as mi'y' O out of the magazme, :agid at the rear` end.

l as indicatedat 33H10 A This enlargement. 38` affords 'a the' width is' enlar 4 n the: head* of the; car- Pamnsea 'Ap-n. 5.,v 1910i FIF shouldenati ilen'wardf sideV adapted to-'ent i' -gage withl'thori'm of'bhe cartridgel and1 prevent lhngitucliixalmovement of the"cartridge .the head or rini registers with the enlarged portion 33 of the outlet opening. In order to support the cartridge stop 30, it is prosliding freely in a longitudinal opening 35 in the rear end of the magazine action bar.

As before suggested, the cartridge'stop 30 is received in and reciprocates longitudinally in the slot Q9 in the rear end of, the action bar and the upper end of the stop, which is inclined or beveled as shown, stands partially in the tubular magazine opening.

The lower end of the cartridge Ystop30 isreceived in a longitudinal slot 36 in the trigger plate and the movement of the stop in connection with the action bar as it moves rearwardly is limited by striking the shoulf der at the rear end of this slot 36 "TlieV cartridge stop 30 has a reciprocating action*- witli reference to the action bar from a position adjacent to the rear end of the action bar, as shown in Fig. 1, to a position at the forward end of. the magazine outlet opening 32, as shown in Fig. 2. The cartridge stop 30 also has a limited amount of'lieciproeating motion with reference to the frame of the fire arm, the saine being permitted by above suggested by theshoulderat the rear'4 end of this slot. For operating the carrier 3l, the action bar is provided with a camv projection37 mounted on a spring arm 37a i arranged in an inclined recess 38 in the rear end of the-action bar, the said cam projection 37 beingarranged to ride up l the slot 36 and limited in one direction as..l

pivotally hinged on the tubular pivot 41. As the action bar moves forwardly, the cam projection 37, engaging in the cam slot 40, i

causes the forward end of the carrier to be thrown upwardly, and upon said cam pro` jection becoming disengaged from the carrier, the latter is thrown down by gravity and the action of the combined trigger and carrier spring 42.

l l l The cam projection 37 j into or across the rear end of the slot 29 in the rear end of the action bar, is adapted also to engage with the cartridge stop 30 and move it forwardly when the action bar is moved forwardly. This cam projection 3T also serves to prevent the accidental displacement of the cartridge stop from its position in the rear end of the action bar when the gun is taken down and particularly when the trigger plate, with the butt stock 18, is removed from the other parts.

The front end of the breech bolt 20 is provided with a vertical flanged groove, as indicated at 20", to receive the hanged head of the cartridge, and the arrangement of parts is such that when the carrier 3l opervided with a cylindrical stein 30el fitting and ates the groove 2Gb will register with lhe enlargement 33 of the outlet opening ot' the magazine.

The mechanism ofthe fire arm shown and described is substantially the saine as that lshown and described in my Patent No.

908,883 of January 5, n1909, and the description of the operationinay well accordingly be restricted to that appertaining to the cartridge stop. In the construction herein shown, the magazine tube being loaded with cartridges in the usual manner, the same will lie in the rear portion of the magazine, end 'to end, as shown in Figs. 3, 4 and 13, with Athe magazine spring Vand follower pressing them 'toward the rear'v in' the usual manner. When the actionV bar is oved rearwardly, the breech block isnnlocked and carried rearwarfy, of course, and the cartridge stop 30 is car ed along with the action bar until 4it strikes the rear end of the slot 3G.. Din'- ing this movement the head of the rear cartridge will be engaging against the slioul- .der 28 at the rear end of the magazine. .When the cartridge stop 3() reaches vitsliinit .fof rearward movement, the continuation ot :the movement of the magazine action bar brings the head of the rearinost cartridge into engagement with the inclined upper end of the cartridge stop, u which it proceeds. to ride, nothing hin ering, and the flangejofthe cartridge head passes partially into-the enlarged portion 33 of the outletopening; where it becomes locked from longitudinal'inovement with reference to the I action -bari As the movement of the action bar-iscontinued rearwardly, the whole of the rearmost cartridge passes over the top ot the cartridge stop 30 and is elevated or moved, vertically partially into the outlet opening 32.' -.The carrier 31 being located immediately to the rear of the cartridge sto'p, receives and4 supports the cartridge in its deflected osition partially in the'outlet opening. hen the head of the second cartridge from the rear in the magazine cnin its normal position standing partially gages the inclined upper lend of the car- 'changes in`and from the construction hereinv tridgestop, itis unable to pass the same, fori the reasonthat the width of the outlet opening 32 at this point is less than the diameter of the head of the cartridge, and the inclined shoulders 25a hold the cartridge down in engagement with the stop. The action bar is preferably allowed to move rearwardly some little distance after the second` cartridge is This obviates any friction of the rst car-y tridge on the second cartridge when the former is being removed from the magazine- When the carrier operates it moves the rearniost cartridge completely out of the outlet Vopening' in the magazine and slides it up the'front face ofthe breech bolt, where it is held' preparatory to being introduced into the barrel. As the magazine action-bar is moved forwardly, the cartridge inthe magazine which was stopped by the cartridge stop assumes the position vin the rear end of the magazine at the outlet opening, and as the vaction bar completes its forward movement the cartridge stop is caught and moved slightly forward by the cani projection 37, at which time all parts assume their normal positions'ready for a repetition of the operation.

In order to prevent cartridges being vaccidentally displaced through the outlet opening' 32 when the breech block'is closed and the act-ion bar is in its forward position, which might perhaps occur-if the arm weie inverted from its .normal position, there ,is provided a cartridge retainer 45 which is adapted to occupy a position over the enlarged end 33 of the magazine outlet opening when the parts are in closed position,

or nearly so. A cartrid e tending to become displaced through tie outlet opening avlien the'magazine action bar was in its forward position or nearly so, ,would obviously come in contact with this retainer and thereby be prevented from becoming displacedv suticiently to be objectionable.

*It is evidentthat modifications and described may `be'made without departing from my invention.

lVliat I claim as new and desire to secure by Letters Patent is:
