To all whom it maagl concern.'

Be' it known that I, EDWARD E. REDFIELD, a citizen of the United Sta-tes, residing in Glendale, Douglas county, State of Oregon, have invented certain ynew and useful Improvements in Firearms, of which the following is a' specification', reference being had to the .accompanying dra-wings, which form This invention relates to magazine or repeating rearms of the slide-action type, in which` the several roperations of extracting and ejecting the emv ty shell, placing the fresh cartridge in the c amber of the barrel and cooking the hammer are performed by the reciprocating movement of a fore-end or grip piece which is generally mounted on the magazine tube below the barrel.V

The invention is illustrated herein as embodied in a rifie which comprises some of the novel features of the riiie shown and described in another application for Letters Patent tiled December 22, 1910, Serial No. '598,7 81. Such features of construction as are common to the rifle shown in saidy application and that shown in the present application will therefore be described only so far as an understanding thereof is necessary to an, understanding of the present invention'. The present case, however, covers some modifications or further improvements of some of .the improvements covered in said former application and some improvements in parts o the gun which were not made the subject 'ofimproveme'nts in said former applica-tion'. y

One object of the present invention is to improve the devices for retaining the magazine in the magazine tube and releasing the same.

Another obect of the invention is to vide improve take-down devices.

The invention is also /concerned with the construction of the eie'ctor mechanism by prowhich the empty shell is ejected from thereceiver, with. the devices for'lifting the fresh cartrid e from the plane rof the magazine to the p ane of the'barrel, and with the slide locking devices.

The various features of improvement `will bel more particularly described hereinafter with reference to. the accompanying drawings in which they arel illustrated and it will be specification of 'Letters Patent.

Application led August 8, 1911. Serial No. 643,058.

Patented Mar. 25', 1913.

understood that. some of `the present improved devices are capableof use independently of otherfeatures of im rovement and in guns of other constructlon than that shown.

In the drawings Figure 1 is a view in siden elevation of a take-down riiie to which the several features of invention are applied. Fig. 2 is a detail view, partly in longitudinal section, of the front end of the magazine and magazine tube, illustrating particularly the devices for retaining the magazine with. in the magazine tube, the scale being larger than that of Fig. 1.

In the firearm shown in the'drawingspth barrel a, chambered to receive the cartridge,

the magazine b, placedl within the magazine.

tube b. and provided with a follower b2.v and a spring b3 by whlch the cartridges.v are pressed to the rear,'tne receiver c, the frame d, and the stock'd are constructed substantially as usual, except as hereinafterfpointed out. The receiver e has, `forward of its rear endand'forward of the takedown joint, a

-shoulder c against which the breech-block abuts in the tiring position, the breech-block passlng rearwardly below the shoulder when t-he gn 1s open. The receiver has at its rear end a rearwardly extended lug c2 which is adapted to enter the frame and has in its underside a notch c. In a recess d2, in the forward end of the frame and entered by the lug c2 of the receiver, is mounted a locking bolt d3 whichis provided externally ofthe .frame with an operating handle d* and is flattened on one side, as 4at d5.' When the fra-me and receiver are lassembled, the 'operatlng handled* is turned tothe ,positionshown in Fig. 10, with the fiat side of the The lug 'c2 then slips over thebo t until the notch c3 stands in line therewith', vwhen the bolt. is turnedbythe handle d4 into -the position shown, for eX- ample, in Fig. 5, sd that it enters the notch and securel. locks the receiverfto the frame. The frame ltself is provided at its lower side with -aA forward extension al"y which bears against longitudinal shoulders 04 on the sides `of the receiver, to guidethe'frame and receiver together properly and also to hold them in proper relationand has at itsforward'end-a toe olf-adapted to. enter a recess,

c5 in the forward end\t of the` receiver as shown in Fig. 5, to prevent fthe liftlng of the receiver with respect to the frame*l It' will now lbe seen that when the leveii. d"-

Fig. 20 is a detail view inof the locking bolt is'turned to the position shown in Fig. 10 the frame and receiver are united by a straight longitudinal movement and are locked together by turning the lever d? 'down into the position shown 1n Fig. 1`.

The magazineb, as usual, is slipped'into the ma azine tube or supprorting shell b from t e forwalrd end. he evices by which it is secured withinthe outer tube or shell are shown in Figs. 2-4. The blocky b",

fitting 'loosely within the forward'VY end Yof I the magazine b and slotted as at b5 to strad` dle `the pin 66, carries at its forward end a finger piece b'/ by which the block can be pulled forward slightly with respect to the magazine b and by which, after release, the magazine can be pulled forward out of the supoprting tube b. The block b4 is also` slotted as at bs, to receive the locking dog b9 which is `pivoted on the pin b and is provided at its rear fend, back `of the block b4,

vwith' a headv b1? ag' ;ainstwhichy bears the spring bs. At its forward' end the dog. b9 .is rovided 'with teethl b which are adapte to engage corresponding teeth 612 formed on 'the .interior of the shell b atv its forward end.' The teeth .Z211 and b1- may be formed conveniently as screw threads. A spring b acts upon the dog b9 to pressthe teeth b thereof 1ntov engagement with the teeth blz of the tube. Theblock b4 is provid d with a cam shoulder t which is adap ed to coperate with a cam shoulder 515 of the dog b". It will now be seen that when the finger iece b is grasped and pulled forward, the lock b is moved forward also to the extent permitted by the dog b, and that in such move- .ment the cam shoulder b1* of the block comovementof the .dog is prevented by the contact of the forward portion of the dog with the interior ofthe magazine b.. The magazine -is thus released easily when necessary, but cannot be disengaged by any moveof the finger piecel bf; .The vbreech block and described in said former application ment other-than. a straight, forward pull"- y e constructed, arranged and "operated substantially as shown` Serial No.V 598,781 having pivoted thereon the supporting and startlng lever which has a lug f to coperate with shoulders (not shown)l onl the left hand side of the receiver, to drop the rear end 'ofthe breechtiti Y inl the frame,

shown in Fig. 9, when block` below the abutment a of; thel receiver andA to start the breech-'bl rearwardly, being actuated for this pu csethroughA its engagement at the lower en withthe ,slidebar. The cockin 1 lever, not shown, pivoted on the starting ever, eoperatesl as usualwith the hammer h which ismovable longitudinallv in the breech-block. The' hammer is held in its cocked position, against the tension of the hammer spring, by ,a sea-rz', pivoted on Vthe breech-block and ada ted. to be engaged by a trigger lever s whic isl actuated by the trigger o, all as described in said former application. Y

The grip piece .lc is mounted upon a magazine tube or shell b' tended rearwardly therefrom a slide-bar k which has at its rear end a lug k2 (see Fig. 16), to engage the sup ort-ing andstarting lever f, which is provldad, at its lower end, with a hole for' engagement with the slidebar, so that the entire rearwardagnd forward movement of the breech-block is` effected through such engagement ofthe slide-bar with the starting lever.

Rearward movement prevented by a slide-lockingvlever 'm (see Figs. 5 and18), which is pivoted in the frame, as at m and has at its forward end a lug m2, which projects upwardly within the receiver into the ath of the lower end of the starting lever y, movement of the starting lever and therefore rearward movement of the` slide-bar k, The locking lever `is not spring pressed, but is thrown upward; into 'locking position by the last forward movement of thebreechblock and is thrown down to' unlock the slide-bar either by the operation of a slideunlocking inger piece or by the operation of the trigger. As shown, there, is pivoted forward of the pivot ofthe slide-bar lever, as-at mia lever m* which at its rear end, m5, underlies end has a cam lug fm. whichprojects upwardly into the4 path of the lower end of the lever f, carried by the hreach-block.l The forward end of the lever m* is thrown upwardly by' a suitable spring m7. rll`hus, as

t e breech-block reaches the limitof its forward movement, the lower end of the lever f acts upon the lever m4t to throw the forward end ofthe lever m upward behind the lower end of the lever f and thereby prevent rearwardmovement of the lever f and of the breech-block unt-il the forward end of the lever m is ele-4 pressed. rlhis may he done .by the nger lever m5,V which is pivcfed at m?- in the frame and is provided., l:tc-rw.ard of the" pivot 'with a spring m1 which throws the rear end am. downward. -rlhe rear end of the lever m8 (see Figs. 5 and 19), is so shaped aste project downwardly within the trigger ythe lever" m 1n as usual and has ex- 1 upward, to release the vthe gun to of the` slide-bar is in Fig. 13, is pivoted to prevent rearward the forward `end* of the locking lever m, and at its forward f ma yment of the breech-block, as the breechf block approaches the limit of its movement,

guard, for operationby the iinger,while its extreme raejnd extends upwardly below rear' of itfs pivot` m. Upward pressure againstthe finger lever mi therefore throws' the forward end of the'lever m" downwardly out of thepath of the lower end ofthe lever f, as shown in Fig. 5,

andtherebyl releases'. the lever f and therefore the slide-bar lc for rearward movement.

The trigge'o, pivoted at o in the frame,

` has a heel 02 1n rear of the pivot o for cooperation wit-h the which is here shownV as a lever toe p ofthe safety p pivoted at p? in the frame and acted upon by a spring p3 which tends to throw the forward end or toe' of the lever downward intot-he path i of the heel 02 of the trigger,.so as to prevent effective movement of the trigger. A

tinger piece p* projects downwardly through the frame so that the safety can be pressedtrigger and permit be fired. The rear end of the lever fm overlies a shoulder 03 of the trigger, so that the pull of the tri ger actuates the` locking lever m to release t l e'slide.

The lifter l, which is shown in its relations with other parts in Figs. 5-9 and also upon a part, to be referred; to hereinafter, which occupies a xed relation with respect to the frame, so that, so far as concerns the immediate functions of the' lifterjZ it `may be regarded as pivot'edv` the frame.- a of its pivot with a cam suiiface Z which cog operates with fwith a notch Z2 rim of the cartridge, with a lift-ing surface 1l", and with al downwardly extended pro- 1; jeetio'n #which forms a cartridge It is provided forward a cam e ofthe breech-block, which coperates with the stop and cut-0H. In rear of its pivot it rhas a fshort, rearwardly extending arm Z and a *cam lug Z7 which is mounted on a sprlng so that it- Z8 (see Figs. 13 and 14),

plunger laterally. In the rearward movey yield as shown 'in Fig. 7 the breech-block acts upon the rearward extension Z6 of the lifter to raise the forward end suiiiciently to cause the forward end to stand in the path of movement of the next cartridge in the magazine, and asthe breech-block moves forward from its rearwardposition, as shown 1n Fig. 8, a double cam lug c"'-on the righthand side of the slide-bar c, near its rear end, coperaties with the cam lug lT to de` ress the rear end of the lifter and raise the orward end of the lifter to its full extent, hringing the cartridge thereon into line with the ,chamber of the barrel. The forward edge of the cam lug is is chamferedoif so that in the rearward movement of the slidehar the lateral surf-ace of the cam lug la pushes the cam lug il laterally into the rear 65 drawnbaclr, relatively. to thev` bre end of the lifter and slipsover it, while the forward movement of the slide-bar the point of .the cam lug k3 engages the rearward -upper surface of the camlugv Z7 and 5 presses the rearend of the lifter downward,

therebylifting the forward end of the lifter to its full height, as shown in Fig. 8, which raises the cartridge into line with the chamber of the barrel so. that in the continued lo forward movement of the breech-block thel cartridge shall be pushed into thechamber of the barrel.`

The lifter l is pivoted in a longitudinal.

slot in a tubular cartridge guide-block c6 which has at its forward end a T head c" which engages vertical grooves c5. and 09 in the side walls of the receiver, as shown in Fig. 21. The block is locked in place by the rearend of the magazine Z) which, as shown ....201 in Figs. 6, 7 and f8, enters Athe tubular forward end of the block. In rear of the tubular forward end y of the guide-block, the guide-waycm', as best shown in Fig. 7, is in- VAclin'ed upwardly so that the rear end of thev cartridge slides upwardly on the inclineuntil its rim reaches the notch Z2, as best shown 'in Fig. 6. yWith the cartridge in this position, the breech-block continues to. slide rearward'over the rim of the cartridge until theflanges@2 atthe forward end ofthe breech block engage the `rim and drawl the. 4cartridge rearwardly and also upwardly, the` ri-m ,slipping out of 'the' shallow notchl Z2.

.. In this wayya -proper engagement .of the flanges 6"" at the-forward end of the breechblock with the rim-of the cartridge is secured, this resultbeing assisted bythe downward movement ofthe breech-block,'.vinto the frame,over the end of the cartridge',-the car-J cf-tridge beingmoved upward at the same time by the first part ofthe'upward movement ofthe lifter.

,The-ejector 1', shown in detail in' l5 and in its Arelation with other parts in Figs.-

` 454 5-9 and 1'1 and 12, receives itsefective movement from a springand is 'cocked,'like a longitudinally`movable hammer,` and re- 'j -leasedby the movement ofthe breechblock in 'the receiver. The ejector has an ejecting 50 `finger r which is withdrawn into aslot in leased. At its rear-end, the. ejector has an z upwardly proj ecting lug which,`inithe'begin' 60 ning' of theV forward' movement Yof the 1 v breech-block,l engages a downwardly proj ecting lu'gosl on the underside of the top of the receiver, so ..that, fimovement Aof .the breech=block,` the v jection 'and having a notc 4ward movement-of the breech-block so that the ejector finger?" is out of the way of the .cartridge as, it is engaged by the flanges e2 at the forward end of the breech-block. When the breech-block is moved to the rear,

with the empty shell engaged bythe flanges,

the empty shell rises up on the next car- 80 tridge partly out'of the grasp of the flanges e2 and at the proper time, as thebreechblock begins to move downwardly into the frame, the lug rs of the ejector strikes a lug lo* on the'upper side of the slide-bar and 85 is raised thereby from behind the lug e4 on the breech-block, so that the ejector is released` and snaps forward with a quick motion and throws the empty shell smartly out through the ejector opening 091. on the right 90 hand side' of the receiver. In the construction just described, the ejectorA is cocked by Acontact-of its lug r4 with the lug 081 of the receiverl as the breech-block begins its forward movement, but thee ejector might be cocked at the last of the forward movement of the breech-block by direct contact with the rear end of the barrel, as shown Fig. 22, in which ligure it will be seen that the ejector p is.constructedsubstantially as above, hav- 10o ing' a downwardly projecting lug .1"5 to'co- Operate with the lug e4 ofthe breech-block .and to hold,l the ejector in its'cocked position against .the tension of the` spring e".v HInstead, however, of having an upwardly pro- 10'5 jecting lug to engage a lug on the receiver, the' forward end'of the ejector projects forward of the front face ofthe' Ibreech-block and, as the'breech-bl'ock approaches the for- 4ward. limit of its movement, makes-contact 110 with the end of the barrel lsothat the ejector 'shallk be `pushed back," relatively' to f the' breech-block; into its cocked position; f

l It will be understood that the kvarious 'changes in `details oli-construction, and ar-115 rangement might -be made 'to suit, ldifferent conditions 'of use or different firearms to which the invention will. be applied, and that theinvention,v therefore, is 'not vlimited -to 'the details of construction and arrangement'120 'shown "and described herein nor togtheuse',l
