Application led December -17, 1912. Serial No. 737,307.

plicable to a shoulder piece, such as a re-` peating rifle or shot gun.

The primary object of the present invention is the provision of a breech block project-ing and locking means disposed within the receiver of the fire arm for automatic release, due to the recoil from the: explosion of a cartridge within the breech ofthe barrel and the effect thereof upon the breech block. V

A further object of the present invention is the provision of a manual controlling means for retracting the breech block to eject tion of the first breech of the barrel.

A still further object of the invention is the provision of a novel means controllable manually for rendering the elevator mechanism inactive during the manual retraction and projection of the breech block.

-A still further object of the present .invention is the provision of a means controlled through said manual means for rendering the elevator mechanism inactive and locking the breech block open, or placing the trigger at safety and also for rendering the manual breechblock controlling means:

active or inactive selectively.

vllith the foregoing and other objects inview which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of t-he invention.

In the drawings Figure 1 is a side elevaticn of an automatic fire-arm made according to and embodying the present invention, the removable plate of the receiver being detached with the breech block and locking mechanism in breech closing position. Fig. 2 is a longitudinal sectional view through the receiver and the adjacent noran unused shell or for the introducloaded shell within theA tion of the stock showing the breech block and lockin mechanism 1n the farthest retracted position due to' the recoil action of the cartridge thereupon when automatically operated. Fig. 3 is a side elevation taken from the opposite side to Fig. 1 with the portion of the stock adjacent the receiver shown in section and with the manually controlled means for retract-ing the breech block in full retracted position. Fig. 4 is a' section taken 011v line 4--4 of Fig. 3. Fig. 5 is an enlarged longitudinal sectional view through the forward portion of the receiver, the cartridge elevator and the magazine holding tube and a.' portion of the magazine, the parts bein in the position when the breech block 1s sealing the breech of the barrel. Fig. 6 is a view partially in elevation and .partly in section, the sectional portion being a longitudinal horizontal sectional view through the exit end of the magazine tube and detachable magazine. Fig. 7 is a cross section taken on line 7-7 of Fig. 5. Fig. 8 is an enlarged detail sectional view of the two intermediate pivoted members of the breech block locking and projecting mechanism. Fig. 9 is a detail view of the exit end of the iexible and detachable magazine with the parts in the position tridges.

Fig. 10 is an enlarged detail perspective view j ofthe breech block, hammer and pivoted sections of the breech block operatin mechanism. Figs. 11, 12, 13, 14, 15, 16, 1 1s, 19, ao, 21, 22, 23, 24., 25 and 26 are detail views of-thevarious parts connected to and carried by the receiver, de-

tached therefrom. Fig. 27 is a plan viewlv of the removable cover of the receiver. Fig. 28 is a cross section through the receiver and breech at the rear of the elevator, showing the lock for the breech block.

Referring to the drawings, the numeral l designates the stock, which has connected thereto the metal receiver 2 which is provided with the reduced recessed portion 3 at the lower portion of the hand grip there- O 3 tion of the detachable and slotted closure 5, the purpose of which will presently appear. In one of the side Walls of the receiver 2 an opening 6 is provided for the reception of the closure 7 the detail of Which is clearly shownin Fig. 27, the same being provided at its forward edge with-the

recessed portions

8 and 9 respectively, the

they assume when filled withv car- Y recessed vportion 8 being for the direction of the ejected shells while the recessed portion 9 constitutes the trap opening for the introduction of the cartridges to the magazine, as will presently appear. rl'he slotted portion or aperture 10 is pro.- vided in the receiver 2 in the forward end 11 thereof and coacts with the slotted portion 9 of the closure 7 for the introduction of the cartrid es into the inner end of the, ma azine hol ing tube 13. The barrel 12 an the magazine 13, as clearly shown ini Figs. 1, 2 and 5, fitv snugly against each other andare insertible within the socketed end 14 of the sleeve 11 of the receiver 2, the oppo: sitely disposed

dat springs

15 and 16 bemg carried by the receiver at this portion and for Contact with the upper and lower portions of the barrel and magazine tube respectively to resiliently retain these mem. bers within the receiver.' The adjacent facesl 17 and18 respectively of the barrel 12 and! magazine 13 are flattened and lit snuglyf together as shown in Fig. 7, an aperture a formed by recessing these faces of the bar. rel and magazine transversely of the same, constituting a means for the reception of the locking pin 19 which is disposed to be projected through the barrel portionV 11 of the receiver and thus lock the barrel and` magazine securely within and to the receiver, a pivoted bail 2O being carried uponthe outer end of the pin 19, as shown in'` Fig. 1-, and compressible within the recessed' portion 21 when the fire-arm is in operable condition. It will thus be seen that ythe barrel lf2 and magazine holdingrtube 13 are readily detachable from the receiver by simal pl removing the pin 19, and in order toretaln the barrel 12 and the magazine holder' I3 in proper connected relation when detached andalso to assist in bracing the same when in attached position, the em bracing member 22 is connected to and surf rounds the forward end of the magazine' tube 13- and is held relatively thereto andl upon the barrel 12 by means of the metal strap 23, the same being reduced to pre vent any interference withthe sighting ofl i the irearm,

The magazine retaining tube 13, as clearly' shown'in Figs.i5 and 6, is provided With the magazine receiving and enlarged bore` 24 which terminates in the reduced bore 25? forming the directing entrance into the receiver, the catch 26 plvoted at 27 being carried by the tube 13 with its cartridge .en` ga-ging lug 28 normally held by the spring! 29 projected within the bore 25 and in the path to engage the cartridge C, the trigger or releasing end 30 of the catch 26 being projected within the recessed portion 31 of' the tube o1' sleeve 13 and in the path ofthespring actuated plunger 32 which is mounted Withinthe bore 33 formed parallel or 34 which, due to the spring 36, is normally lprojected toward the catch 26, the purpose of which will presently appear.

The detachable and flexible magazine 43 is used in connection with the tube 13, and thus renders the necessity of the introduction of the cartridges C through the apertures 9-10 of the receiver into the bore 25 of the tube 13 unnecessary, as my number of these magazines may be loaded, and the empty one removed to be replaced by a filled one. In the outer end of the magazine is attached the4 plug 37, which as shown has mounted therein a pivoted lever 38 havin the operating button 39 eX- teriorly o the` plug 37, the spring 40 being .provided to normally hold the lever 38 and the locking pin 41 in the position as shown in Fig. 5, so as to engage the annular slot 42 in the outer ond of the tube 13 and thus lock the magazine 43 within the tube 13 and against outward displacement. The body portion of the magazine 43 is preferably made of coiled fiat wire thus providing a flexible cartridge holder, the same boing reinforced by the

intermediate bands

44 and 45 and the longitudinally disposed stiffening Wires'46 which are connected at their ends to the lug 37 and the band 45 and threaded throug the band 44 or between the band 44 and .the coiled portion of the magazine. Connected to the band or sleeve 45 and projecting forwardly therefrom, is a flat metal guiding arm 46 and-a longer cart-ridge retaining and guidin arm 47. The forward ends' of these guiding arms 46 and 47 are disposed for sliding movement at diametrically opposite points within the cartridge directing band or sleeve 48'V which is'mounted for inward' sliding movement vupon the extreme exit end of the magazine 43. The free end of the metal arm 47 is `inturned as at 49'anrl projects to engage the rim of the respective cartridges and retains the last one within the magazine, While when the magazine is empty as shown in Fig. 6, the end 49 engages the headedr portion 50 of the cartridge ejectingpinor stud 51 to prevent the too far extension ofthe same without the magazine and tothus limit the extension of the operating spring 52 of the ejector 51,

said spring 52 being disposed Within the magazine 43 and abutting the inner end of the plug. 37, as shown in Fig. 5.

In order to permit the introduction of a cartridge within the rear end of the magazine 43 when the same is Within the tube 13, the trap 53 is provided, the same being pivoted upon a pin 54 lwithin the recessed portion formed in the side Wall of the tube 13, its lu 55 being abutted by the spring 56 to normaly hold the trap 53 in the position as shown in Fig. 6, but permitting the same through 'the slots' 9-10 so that the cartridge .mayr-be inserted within the bore 25.and the :magazine 43, the bul-let end of .the cartridge being disposed against :theouter endbf the ejector 51.

In order to provide 'a means to prevent the falling out of the cartridge() -when it is .in the position as shown in Fig. 5, and after` the-magazine 43 has beenremoved and before the insertion of -a filled one, the catch '57 is pivoted upon the pin 58 and is bodily `-carried by the tubular member 13 in .one wall thereof, the spring 59 being disposed to hold .the cartridge rim engaging end 60 projected .within the bore when the tube 13 is detached from the receiver, the engagement of the receiver with the catch 57 depressing the spring 59 and removing the hooked end 60 out of the bore 25 to the position as shown in Fior. 6 when the parts are assembled.

Mounted for resilient V.tilting andswinging movement vwithin the forward .portion of the receiver, 'is 'the cartridge receiver and elevator 61, particularly set forth in detall and in perspective. invFigs. 22 and 23, the

same being provided with the transverse' elongated slot or aperture 87 therethrough for surrounding the. in 88 bridging the receiver and formingt e pivoting means for the elevator 61. The free end of the leaf spring 62 is seated within a recess 63 upon the under side of the elevator and forwardly of the pivoting pin 88 and thustends to elevate the forward end of the elevator from the position as shown in Figs. 1 and 5 to that shown in Fig. 2. The upper surface of the elevator 61 is recessed as at 64 for the reception of the cartridge as shown in Fig. 5, the bridging portion 65 forming a guiding means for the pin 66 which extends and slides longitudinally of the elevator 61 at the bottom of the cartridge receiving portion thereof and has its catch end 67 normally projected by the pin 68 and spring 69 into engagement with the projected end of the pin 34, to thus lock the elevator in the position as shown in Fig. 5 and against accidental upward movement. The opposite end of the rod or pin 66 is attached by means of the pin 72 to the cartridge abutting plate 71, said plate 71 being pivoted at 70 transversely of the rear end of the elevator 61 and for engagement with the base of the cartridge as clearly shown in Fig. 5, so that the action of the spring 52 upon the various cartridges Vwithin the magazine and within the bore 25, will tend to push upon the cartridge within the elevator and thus move the plate 71 rearwardly to retract the pin 66 against the spring 69 and thus release the catch end 67 from the pin 34, so that the manipulation of the breech block 73, as will presently appear, .will cause the movement of theelevatorl from the posi- '..tion-.in Fi g'. 1, to that shown in Fig. 2.

.'Ihe breech block 73 is provided upon opyposlte sides with 4longitudinally disposed grooves .74 which coact with ribs 74 formed uponthe inner adjacent faces of the receiver so that the breech block 73 will always be in alinement with the breech end of the barrel 12 and in either position as shown in Fig. 1 or Fig. 2. The forward end of the breech .block -73 is provided with the .spr' cli or cartidgeextractor 73', which asute b ock 1s moved from ,the position as shown in Fig. 1 vto `the position as shown in Fig. 2, en-

gages the rim of the cartridge within the breech of .the'barrel 12 and carries the same rearwardly .to Abe finally engagedby the .ejecting member 75 which is connected vto the receiver as shown in Fig. 2 and has its y free end 75 disposed to engage the rim at the closed side of the receiver and throw the shell-.outwardly and through the -recessed or slotted portion 8 of the cap or closure 7, thus extracting and ejecting the shell before the introduction of the unused cartridge 'by the elevator 61.

f The under surface of the breech block 7 3 is. recessed at 75, Fig. 5, and into this recessed portion is adapted to tit the curved portion 76 of the elevator 61 when in the position as shown in Fig. 5, the forward end Aof the breech block when in the position as Shown-in Fig. 2 being disposed to engage the upper rear portion of the cartridge C t0 move the same from .the elevator into the breech of the barrel 12 when the breech block 73 is moved to the position as shown in Fig. 1. A

In order to cause the breech block 73, to tilt the .elevator 61 from the position of Figs. 1 and 5 to that of Fig. 2, the curved edges 76 of the elevator are contacted by the inclined face 75a of the breech block during the retracting of the breech block,

the elevator being slightly depressed against the spring 62, and so moved that the cartridge carried thereby, after the used shell has been extracted and ejected by the eX- tractor 73 and the hook 75 of the ejector 75, has its base presented in front of the lower front end of the breech block. Thus the forward movement of the breech block to breech closing position will direct the cartridge in the elevator to the barrel 12, and downwardly vtilt the elevator, causing it to assume the position of Fig. 5, to receive the next cartridge from the bore 25.

To provide a means to lock the breech block retracted after the last cartridge has left the bore 25, and thus notify the marksman that such is the case, the vertically slidable lockingpin 78,is provided, and is disposed, as will presently appear, to enter the recess 77 formed in the projection 77 of the breech block, whenthe breech block isfully retracted and thus ock the block against' To sert forth this operation fully,

' is raised by its spring 29 and its end 30 engages the head 32 and projects the pin 34 beyond the bushing 35 and into engagement with the catch 67, but asthe 4ejector pin 51 is pushing upon the cartridge in the elevator before its delivery to the barrel, :the catch 67 is retracted, but is projected when the cartridge is placed in the breech. Thus when the elevator is lowered by the closing. breech block, the projected-catch 67 Kengag the projected lock 34 and 4thus the free front end of the elevator is held :against rising. When the breech blockV is retracted, due to the recoil from'the last cartrid e within the breech, the engagement of the4 reech block with the eleva-tor due to the front end of the 4elevator' being locked, causes the rear end of the elevator to befdepressed, so that the spring '62 is depressed and the hook .85, of the lever '84, is also depressed, it being in engagement with the elevator through the recess 86. lThe forked end 82 of the lever 84 is now raised and through the spring 81, elevates the bolt 80, to place the lock 78 in the path to be :snapped into the recess 77 of the breech block when the bolt is in the position as shown in Fig. 2, locking the'- breech block lagainst closing. The empty magazine 43 is now removed from the tube 13 ,and a filled one inserted, its foremost cartridge-being projected into the awaitingV elevator andlreleasing the catch 67, so that' the vspring 62 eleva-tes l the --elevator to 'the a position of F ig. v2. The upward movement: of the elevator carries" the hooked end 85` ofthe lever 84 upwardlyfcausing the forked end 82 of the lever 84 to swing down and:l carry the rod 80. This movement pulls the lock 78 out of the recess 77 of the breech f block 73. Thus the upward movement of the elevator automatically releases the breech block permitting it to close and carry with it the cartridge in the raised elevator and lace the same in the breech of the barrel 12. ilowever should it be desired to release the breech block to close without loading the barrel, the button 138 Vis pulled rearwardly 'to pull the lever 133 which engages the pin 132 and pulls the rod 171 rearwardly and against the tension of its projecting spring 174, moving the recess 175 of the rod 171, from above the projection 79 of the bolt 80, and placing the end 175 into engagement therewith. This depresses the lock 78 and releases the breech `block to the action of the spring 105 and it is closed without de-A livering a. cartridge to the barrel. The au- 2105 1|'v-1tl1iir2t.he bore `98,150 -that the act-ion 'cfg-the .spring willlaiormally depress the mausi toma-tic retraction of the breech block, due to the cam 77 engaging the projection 79, insures the depression of the lock 78, so that it willnot lock the breech block as long as there is a cartridge in the elevator 61.

At the rear under side of the breech block 73, two apertured lugs 89 are through the apertures thereo is dis osed the pivoting pin 90 by meansof whic the forward end off. the forward member 9laof the breech block locking device is attached, this breech block locking device being composed of the three

members

91, 95 and 97 whichwhen in the position as 4shown in Fig. 1 'will provide a rigid lookin means to hold the breech block closed, to e operated, as hereinafter set forth, through the recoil of the breech block 73 and to automaticallyl return the same to breech closing position.

The member 91 is provided with the apertured lug in 93 which provides the pivotin means or 'the spaced apcrtured ings '94 o the intermediate member 95, a piu 96 being disposed transversely through the member 95 intermediate of the ends thereof and forming the pivotal connecting means for the rear member 97 of the 4breech block projecting and llocking device. f

The intermediate member 95, as clearly shown in detail in Fig. 8, is provided with the longitudinal bore 98 therethrough, and disposed for sliding movement therewithin is a plunger 99, connected to the resilient rod 100 whose forward .looped endis mounted upon the pin 102 betweenthe spaced lugs 101 of the member 91, a retaining; disk 103 being disposed within fthe outer end of the 'bore being held in position by means ofthefsiring catch orv lock 104. This rei-sk is disposed to retain the spring plunger99`=and thus vhold the members 91 and 95 in flocked position, as shown in Figs. 1 'and 8, with the abutting faces 106 and 107 of the members 91 and 95 in contact to limit the upward movement of the

members

91,95 and 97 when in the position as shown in Fig. 1. The .projecting vvend 108 of the member 95 is disposed for movement between the spaced end of the member 97 so that `the movement of the members 91 and 95 from the position as shown in Fig. 1 :to that shownl inFig. 2, when the two members 91 and-95 are moved, will be downwardly or exed.

. The member 97 'is provided with the .elongated slot r109, through which is projected Athe fixed pin 110 carried by the receiver .2 and -which provides a means for limiting and directing the movement of the member 97.- Disposed within the slot 109 between the forward vend thereof and the -pin 110, a. spring 111, which normally tends to rovided and 92 through whichprojects the hold the-member 97 in the position as shown 1n` Fig. 2 or forwardly Within 'the 'receiver Mounted in and carried by the breech I block 73 is the spring retracted lirinp'in 112, the enlarged hammer receiving en 113 being mounted within the bore 113 of the breech block, and so that lthe spring 11,4 there-within exerts a tension to normally hold the hammer 'receiving end of the 'pinv 113 exteriorly'of the-breech block, asA clearly shown in Fig. 4. The' two parallel bores 115 are provided within thebreeCh block 73 oiie upon each side of the firing pin, and v disposed for sliding movement 'therewithin are the fplungers 116 connected to the inner. ends of the hammer guiding and actuating arms 117, the saine passing tliroughjthe reduced apertures 118 of the breech block 73 and carrying upon their outer free ends, the hammer block 119. The spi-'ingsllGl are disposed upon the rods 117 within the respective bores 115 between'the rear endg of the same and the plungers 116, and thus exert a normal `tension to hold the hammer; 119 toward and -into violent engagement? with the 4pin 113 to operate the firing pin' to explode the fulminating cap of the "c'art-ridge C. An arm 120 is connected to and carried by the `hammer 1 19 at one side thereof, 'being uided in its sliding movement by a groove orined in the receiver 2, the same having formed upon'its free end, at the under side thereof a hook o r catch 121 disposed to engage the hooked end 122 of the trigger actuated lever 123. This trigger actuated lever 123 is pivoted as at 124 to the receiver and has its downwardly -projecting arm 125, which-is formed at right angles to the arm 123 as clearly shown in Fig. 11, provided with the tri ger engaging lower end 126 and with the at spring 127 which normally -exerts a tension to hold the arm 125 outwardly from the receiver wall and in the path to be engaged by the lug 128 carried and actuated by the trigger 129. The trigger 129 is mounted for movement upon the pin 130 carried by the receiver 2 at a point intermediate of its'ends and near the forward portion of the slot 4 of they receiver. v

In order to provide a safety means whereby the actuation of the trigger 129 will be nedective as regards the arm 123, a rounded, shoulder or cam 131 is formedupon the arm 125 and is disposed in the path to be engaged by the prong 132 of the lever 133, said lever 133 being disposed within the rear portion of the receiver and pivoted lupon the pin or shaft 134 mounted in the receiver. The upper end 135 of the lever 133 is fitted within the bail 136 projecting through the elongated slot 137 of t-he receiver near the hand grip portion thereof, and carried by the pivoted button 138 whose lower end is mounted upon the' extreme 'is disposed 'within the angular recessed portion '139 formed in the receiver 2, the button being held against outward displace- 'ment by means of the detachable plate 140 and normally held in intermediate or operating 'position as shown in Fig. 3 by me'ans of the small spring 141 in Fig. 3. Thus 'the movement of the button 138 to the rear of the slot` 139 against the tension of the spring y141, will operate the finger 132 todepress the arm 125 and thus move the end 1'26 thereof out of the path to be engaged by the lug 128 of the trigger 129, thus permitting the actuation of the trigger without operating the

arms

125 and 123 and releasin the hammer 119. When the button 138 is in the forward position as shown in dotted lines in Fig. 3, the movethus moving the same upwardly and to the rear upon its pivot 124 to release the hooked end 122 from engagement with the hook 121 which action releases the hammer 119 to the action of its springs so that the firing pin is pro elled to cause the explosion of the ca'rtri ge C disposed within the breech of the barrel.

In order' to provide a means for assisting in the downward flexing of the members 91 and 95 of the breech block locking device, and also to act as a spring buffer for the hammer 119 and breech block 73 when both are propelled rearwardly by the action of the exploded cartridge, a plate 142, as`

the curved surface 95 to ride upon the ment of the trigger 129 will cause the lug n curved surface 142 and thus start the prol jecting members 91 and 95 from the position as shown in Fig. 1 to that shown in Fig. 2, 'the continued rearward movement of the breech block 7 3 causing the members and 95 to assume the position as shown. in Fig. 2 and consequently the compression of the spring A105 carried by the member 95. The buffer block 143 is carried upon lthe forward upper face of the lug 142, and

has its pin slidably mounted therein, the spring 145 being disposed upon the pin 144 between theadjacent faces of the lug 142 and the buffer block 143, said buder block 143 being disposed` in the path to be engaged i by the rear face of the hammer 119 as clearly shown in Fig. 2. It will be seen that when the parts are moved to this position, the hooked end 121 of the arm 120 will be car-` ried rearwardly and "slide upon and engage the hooked end 122 of the hammer locking arm 123 so that when the breech block 73 and the flexing members 91 and 95 are moved, due to the spring 105, from the position shown in Fig. 2 to that shown in Fig. 1, that the hammer 119 will be held against the tension of its springs, or in the position as clearly shown in Figs. 1 and 4. As before described, this action also causes the actuation of the cartridge elevator 61 from the position as shown in Fig. 1 to that shown in Fig. 2 and again to that position as shown in Fig. 1, the elevator thereby lifting the cartridge from the mouth of the magazine and presenting the same to the breech of the barrel 12 so that the projection of the breech block 73 into breech closing position will cause the cartridge to be seated within the breech of the barrel and the consequent depression of the elevator 61 from the position shown in Fig. A2 to that shown in Fig. 1.

As it is desirable that the breech block 73 be manually retracted to permit of the introduction of the first cartridge within the breech of the barrel 12, a pin 146 forms the medium for connecting the forward end of the rod 147 to the member 95 of the breech block actuating device, said rod being extended rearwardly and above the clo v sure plate 5 of the receiver. The pin 148 is carried by the rear end of the rod. 147, and has disposed thereupon the two anti-frictional rollers 149 so that a means is provided for anti-frictionally guiding the rod 147 during the flexing and straighteningof the members 91 and 95, and also provides a means whereby the rod 147 may be pulled upon to flex such members and retract the breech block 73. In order to accomplish this, the spaced upper end 151 of the lever 158 is pivoted upon the pin 130 and astride of the projection 128 of the trigger 129, so'

as to no-t interfere with the manipulation of the trigger 129, while pivoted upon each side of the lever 158 intermediate of its ends, as at 152, arethe two links 153. The lower ends of these links 153 are secured by means of a pin 154 intermediate of the ends of the hand lever 155, said lever 155 being pivoted at 156 to the receiver so as to have movement to and from the lower portion of the receiver, with its free end 157- disposed adjacent to the hand grip portion of the stock and in ready access to the marksman. The lower end of the lever -158 is connected by means of a pin 158, to the lower end of the arm 159, saidl arm 159 being grooved as at 160 so that the arm may slidably ride upon the rod 147 and in turn so that the rod 147 may slidably ride in the groove 160 of this arm. Carried by the upper end of this arm 159 are vthe two oppositely disposed antifrictional rollers 161 which are disposed, when the lever 165 is moved upwardly to the positionas shown in Fig. 3, to engage the anti-frictional rollers 149 and pull upon the rod 147 to manually move the pivoted members 91 and 95 from the position shown in Fig. 1 to that shown in Fig. 2. Thus it willl be seen that a manual means for causing the actuation of lthe breech block 73 is provided, the parts being presented to their locked and breech closing position by the action of the spring 105 upon the plunger 99.

In order to lock the lever 155 against ac cidental upward movement and against the manual manipulation of the breech block 73, a pin or rod 162 is pivoted to the end 157 of the lever 155,;and projects upwardly through the verticalV slot 163 formed in the extreme rear portion of the receiver, the same, as shown in Fig. 21, being provided with the recessed portion 164 adjacent its upper end and in the path to be engagedby the lookin bolt 165 slidably mounted within the bloc 167 mounted within the receiver and forming the abutting and guiding means for the rollers 148V of the rod 147. Mounted upon the pin or lock 165 within the block 167 is a spring 166 which normally holds the lock 165 in the position asshown in Fig. 2 and consequently seated within therecess 164 of the arm or pin 162. Thus when in this position, the lever 155 is held against movement toward or fromthe receiver of the fire-arm.

In order to manipulate release the arm or pin 162 to permit of the movement of the lever 155 from the position shown in Fig. 2 to that shown in Fig. 3, the forward end of the lock 165 is provided with the hooked terminal 169 which is disposed in the path to be engaged by the reduced end 170 of the lever 133, this action occurring when the button. 138 is moved to the .rear of the recess 139.

From the foregoing description, taken in connect-ion with the drawings, it is evident that an automatic repeating fire-arm 00nstructed according to and embodyingthe .the lock 165 to l present invention, has elements which p'ermit of the rigid securing of the barrel lto the receiver andstock so that the relative position of the magazine, barrel, receiver which Will transmit motion to =the

91, 95 and 97 causing the slight depression of the spring 11-1, the movement of the member 95 against the curved lug 142', causing the members 95 and 91 .to be deiiected 0r moved downwardly, .giving a cushion action to the breech block due to the compression of the spring 105, the ejector 75 being brought into place to eject the used shell carried rearwardly by the breech block 73 so that the elevator 61 With the new` cartridge may be properly positioned to place the cartridge with the bullet end toward the breech of the barrel 12, the same being forced home Within the breech upon the projection of the breech block 73 due to Vthe 'action of the compressed spring 105 in straightening the members 91 and 95 from the position as shown in Fig. 2 to that shown in Fig. 1. It is also evident that when the elevator has been moved from the position shown in'Fig. 2 to that shown in Fig. 1, that the next cartridge Within the bore 25 due to the spring 52 will be moved out of the bore 25 into the receptacle of the elevator 61, its base being projected against the pivoted plate'71 so that the catch rod 66 will /be released from the catch rod 34 of the tube 13, the elevator being held in the position shown in Fig. 5 by the closed breech block 73 and in ready position for elevating the cartridge upon the retractionv of the breech block and the ejection of the. used shell from the receiver. l
