To all 'whom 'it may concern.'

Be it known that I, PAUL' commercial counselor, a subject of the King of Wrtemberg, -residing at Oberndorf-on the-N ecker, in the Kingdom'of Wrtemberg,

Germany, have invented certain new and useful Improvements in Firearms, especially recoil-loading Weapons 'with sliding barrels, of which the following is a full, clear, and exact description. v This invention relates to improvements in fire arms, especially recoil-loading Weapons with sliding barrels. fv

' Theim rovements relate especially to the so-called ook of the weapon, that is to say, tothe breech bolt and its locking mechanism, as Well las to those'parts which are arranged i inside the breech'bolt or are in exterior coninvention, the arrangement is such that the adjustment of the rilie for single loading and `automatic'. loading-is regulated with the aid of the'so-called barrel arrester (which serves the purpose of holding `the'barrel in its rear- Ward osition While theV breech bolt advances andthat by means of this adjusting device, the riiie can also be placed at safet AA further important novelty is that, in

accordance With'tlie inventiorn-the movable barrel is spi'ii ig'butf1 ered at both ends for the advancing as Well as'the receding movement, so that im actis eliminated and a shockless Working o the weapon, when opening as well as when 'closingt'he'breech is attained.

Improvements have also been made in the iringdevice, which, With the aid'of newA and simple means, is adapted to prevent prema` ture ignition of the cartridges before tlie Abreech is locked when shootinfor this purpose, 'in accordance .with invention,

mechanism vhaving a compulsory movement and connected to the firing pin, is provided which retains the point of the firing pin bei hind the friont surface of the `breech bolt MAUSE'R, royal until thebi'eecli is actually in position.

The invention relates further-to a new con-i f struction of the releasing device whereby the interlocking of'thestrigger and trigger studs and the ensuing pulling of t'lile trigger, can

only take lace when the breech is 'in' osition and (a arts have taken up their c osed position. 'Tllie trigger and trigger studs are for this purpose so mounted as to engage and' be periodically released from one another. At the same time the invention also relates to improvements with regard to thoseauxiliary parts which are essential i or thremoval of the fired cartridge, namely, the extractor and e`ector.; the extractor is so mounted in a close head-like front part vof the breech bolt astobe insured against slipping or jumping ofi, Whereas with regard` to the ejector the important and newimprov'ementis effected by this ejector being elastically formed in J ,order to yield somewhat upon shocks taking place, whereby the ,detrimental strain is eliminated.

The series of improvements in accordance with' the invention iinally end's'with the arrangement of an adjustable auxiliary magazine for increasing at will the size of the'stationary magazine, the former being so formed that it can be fastened to the stationary magazine in a simple and easy manner in y order to forni an extension of thela'tter, the capacity of which can thus be increased for a' large number of cartridges. When using.

' this auxiliary' magazine no alteration of the stationary magazme or breech is necessary, as the interchangeable magazine. completely corresponds With the stationary magazine,

similar manneras with the stationary magazine.

In' the accompanying.drawings is shown a recoil-loading riiie with sliding barrel (Mau- Tand the feedof the cartridges takes place in a.

sers system) provided with 'f tlic' improvements in accordance with: the

present inven-` tion,` in Wlnch drawings;

The general arrangement of 'theweapon is as followsacThe breech system consists essentially' of `the following parts, namely: the

mainly fork-shaped breech frame h connected at its fore part tothe barrel Z andl y ieee g,of the weapon, the breech bolt 7c, wiich 'performs isi Viff-itsopening and` closingy movement inthis breech casing or frame h, the nnnor breech g, which temporarily receives the firing mechanism and which is located in the rear n Wall of the breech frame h, and the locking f-u' bolt b movably mounted in the rear part of the breech casing or frame 7L and adapted to invention, formed like a U-shaped block b toitskrea'r-most position.

the breech bolt k in its rearmost osition, the barrel casing or framebeing hel 'fast rl `he oscillating in a similar manner to a cradle, and, \1n consequence of its extending beyond l' itpw rockingfcenter, is capable of acting as a double-armed lever.` This block is susby means of lateral pins or trunlpended,

riding forwardly slanting nions a, in corres po'ckets h in the reech frame h, these pock ets h1 being preferably open at the top so that, after removing the lid 'd which closes the rear par't of the breech frame at the top, thelocking block b can; be taken out at the top withoutdifiiculty. The two fore and rear f arms b1, b2 of the locking' block b, are pro-'- vided at their respective ends with noses or projections cl c2 (liigs- '2 and 3), for which corresponding cavities g1 g2 are provided in the stock or frame pieceg on vwhich slides -the breech casing or frame h carrying the locking block (Figs. 1, 6 and 15)-, so that by the coaction ofI these noses and apertures during the toand fro-motion of the breech casing or frame, the alternate stopping of the block in the locking and unlocking positions is eHected Awith a rocking swing around its pivot.

The inode of `action of the locking block during the unlocking and locking isclearly` shown in Figsft, 5, 6, 7,8 and 10. In the locking osition, (Figs. 6, 7 and 8) the lock-Y ing bloc with its forward arm b, is pointing down, and with its'rear arm b2 up; the projection c2 of the rear 'arm b2 has passed out'of the corresponding aperture gi and lies on the full part of the slide rail, whereby the block is held in its above nientionedvlocking posi- ,tion After the weapon has been fired, the breech casing or frame goes back with the locking block, thejprojection. c1 ofthe for-v ward arm of the locking block' rising out of the aperture g1, while the4 projection ,c2 of the rear arm b2 of the locking block descends into the aperture g2. In consequence of the upwardvmotion of the projection-c1 in the aperture g,rthelocling block is swung so, that its forward arm is -u Ward and" its rear arm downward, While t e projection c2 enters the aperture g2 as above stated. As soon as this happens, ythe breech bolt flies back by itself show theparts in this' osition', that is the locking block b in the un' ocking position, and

Figsfll, 5 and 104 'return movement of the breech bolttakes placeimmediately it reaches the rearward -pos-itiomas soon as the same'approaches the lend of its course,^ the breech casing or frame is also released, so that the breech bolt, breech casing or frame and/locking block, then pass mutually into the. locking position, While, as soon as the necessary play is provided by the projection cl entering the aperture'g,` the locking block is swung from the unlocking into the locking position b the cooperation of the projection c2 and t e'slant\ ring surface of the aperture g2. As clearly shown'in Fig. 8, the locking block, in the locking position, takes up such a position that'the front surface of its front arm b lies behind the rear end of the breech bolt, so

that when the weapon is fired, the 'gas pressure or locking pressure is taken up by the whole ofthe front surface b0- of the upper cross piece of the locking block, which surface b0 abuts against the corresponding upper. rear surface k" of the breech bolt. All the surfaces, during the locking, taking the pressure of gas in the direction of pressure, are hereby 'approximately at the same height,

that is to say,'they are arranged in the same dially so that they are capable of taking the gas or locking pressure on their length.

In the above described construction, ni les 'kx are provided, symmetrically to t e arrel axis, at the' rear end of bothsidesof the breech bolt, in order to obtain greater bearing surfaces and a s mmetrical support in the direction of the axis, the front surfaces of the front" arms li of the locking block Ab' abutting against said nip lesV in the locking position- (Figs. 6, 7 and 8 es 'theupper supports lc, boare provided, wh ich in combination, insure a perfectly sym-v .xnetricalsupport with ample security. The rear' surfaces of the breech bolt nipples kx are so corres `ondingly hollowed out to the curve radius o the front surfaces of the block arm b1, that a close touch-andreas movement of the block on 4the breech bo tis obtained.

Thus two lateral. sipports, the nipples le", and the arms b'hbes1 Corresponding 'grooves or channels bx aref orme on the innerwalls of the locking block i for the nipples kx, and in which-saidnii-p les slide when the breech bolt flies back. us

an'exactl guidance for the breech bolt-is obtained, and the locking bolt itself, while sliding into its unlockingr position, vis held rigid .byl the` breech bolt or its nipples until the,

breech bolt has passed into the locked posiion. The breech casing or frame, as previously mentioned, is, as soon as it has passed 'nto its rearmost position, held fast until the f ,ackward flying breech bolt in the breech g'jasing or frame has completed its return movement and again liying forward ap' A"proaches the locking position.

soon as the breech bolt is close` to the end of Hence, as

'its path, the previously retained breech casing or frame is released, so that then, as mentioned in the description oi`- the locking block action, the breech casing or frame and the locking block can pass, simultaneously with i the breech bolt, Which completes the forward motion with said breech casing, into theV locking position. In this case a vertically movable stud z is arranged in the magazine ledge of the stock or frame iece g for fixing the breech casing 'or frame said stud having a lateral rojection'g:1 at its upper end and beingV lingue-nocd by a plate s ring w which lies with one end supporte on the stock r frame piece g, While the other end acts lindirectly on the stud. This plate the-:tendency to hold thelstud in t e arresting position, in which position it projects in the path'of` the breech casing or frame h and in that of the breech bolt k.

, The breech frame or casing has a projection y on its sideand a cavity "'y in front of this 'projectionjy `both so arranged that, when the breech frame creasing h is in its rearward position, the stud x is thus able to enter the cavity y1 when the breech casing or frame is in this position,and to lace itself in front of the projection y.. Tiis effects the fixture of the breech casing or frame and barrel in the rearward osition. The breech bolt is rovided on vits ower side with a corres on ing longitudinal groove c, .in order to e able to slide over'the stud, vwhich groove ends at the rear in an oblique surface k2. This surface is so arran red as to meet the stud when the breech thereby moves the stud downward, so that the shoulder .jul of the stud discngages with the cavity y! of the breech casing or ,frame h; the projection y is thus freed ol' the stud x, so

that the breech casing or frame, with theV locking block, is advanced by the correspondin propelling spring, and thus the locking lock 1s able to swing into the locking position. This securing mechanism is simultaneously capable ol' fulfilling another extrernely important purpose; without the same, when using the breech bolt Without,

nipples, ,the locking block might be moved too earl linto the' ocking position, that is, duringt eadvanceof the breechbolt through theA locking block, in conse( uence o-l' the advancing movement of the `frame, whereby the front end ol' the locking olt advances and f reeel] casing' or -sition when the breech bolt is Without n ipples, and the locking block is unable to swing l with its forward end down until the entire breech bolt has passed out of the locking block.v lIn this construction already described, the -arrangement is such that the arrester, also acts as an i stud :c of the barre important member of an arresting device on .which the action of the Weapon, used as a sin le-loader or automatic loader, depends, en moreover, by means of Which the securing of the parts. against firing iseffected. For this purpose, as shown in the drawm s, an arresting device x2, x3, 'v connected to t e stud, is provided, the principal art of which is the rotatable adjustin dis 'v provided with rests or recesses. 's rotatableA disk is mounted on a pin on the left hand side of the stock or frame piece g, near the end of the latter, and, so as to be easily manipulated from outside, it is provided with an upwardly inclined arm 'v1 projecting above the magazine ledge, which arm has on its outer side a button 'v2 destined for the thumb. The double armed lever x2, 'm3, which is pivoted inside the stock or frame piece g, acts as an intermediate member for transmitting mo-- tion between the stud and the adjusting disk o; the front long arm x2 of this lever engages in the stud x and is influenced by the strong plate sprinfr w1 iixed to the stock or' frame piece g, while the short rear arm :t3 of the lever rests on the rim ol' disk fp, Which rir i is rovided with a number offs'teps or rests.

.he disk 'v is provided onits outer surface with three rests 1, 2 3, by means ol' which the single-loading, automatic loading and safety, positions are regulated. Engaging with these rests is the projection w3 of a y plate w acting as a spring catch, which iskcwise fastened to the stock orl'rame piece g and which, with its powerful rear spring arm and engaging nose w3, regulates the intermittent rotation of the disk from one position to the-other. The screwr for'iixmg this spring plate also carries the spring w1, While the pin w2 fixed to said spring plate, acts as a support for the lower arm of the spring. r

As shown in Fig. 1, the position of the adjust-ing` disk o for single-loading is lsuch that the stud :1: is held by the dgublezlever x2, w3, in the raised position, in which it places itself with its upper shoulders1L frontv of the groove 7B in the breech bolt, and thus pre;-r vents the latter from advancing. For this single-loading position, the nose w3 of the spring plate 'w engages in the rest 1 of the ad` justing disk o. l/Vhen thc parts are in this' position, the function of the adjusting mech-i block would be pressed down onthe mlrancl mgbreech bolt and cause the latter Lo be anism isc such that the stud fr, which I asses downy out of the track when the breec Ibolt recedes, again rises as soon as the breech holt reaches its rearniost position, and passes in front of the projection 7c". of the breech bolt, which latter is prevented from ad- V vancing until the release of the stud at is' ei'-` ,iected )y the adjusting mechanism. In order to obtain a momentary release of the stud without having to turn the adjusting disk to the rest 2, for automatic loading, the rest 'i0 cavity l is provided with a lateral outward slanting surface'cx, and a raised stop o is provided on the rear side of the adjusting disk in 'front of the flat part I corresponding i. to the position of iest 1. The rest slant 12X allows the adjusting disk to be slightly turned back against the spring pressure of the spring plate w; during this backward rotation, however, the stop o operates the double lever a, 1', in such a manner that the stud x is .20 slightly depressed, its shoulder x1 consequently releasingr itself from the projection 7c on the breech bolt, so that the latter is able to advance. This action ,is effected almost in a moment by a light rearward pressure pf the thumb on the button c2 of the arm ful of the disk o. Il' the button v2 is released after the breech bolt has been released, then the parts of the adjusting mechanism, the disk fr, and the double lever 1r, w3, immediately return to the position corresponding to the normal position of the rest 1 for single loading; hence the stud a'. is able to assume its catching position when the next shot is fired. The position of the adjusting device just described, for momentary release for single.

loading, is shown in Fig. 4, wherein it is evident that the denoted position only. lasts while the thumb pressure acts on the button c2. It follows therefore that the parts cane 40 not remain. in this intermediate position Without this pressure, but immediately return, upon the pressure relaxing, to the nornial position forrest 1. When adjusted to the position 'for self-loading; as shownin Figs.

5, l2 and 1.6', the adjusting' disk c has turned from the position of rest 1 to that of rest 2, so that the nose w3 engages with the rest 2, While the rear arm ai of the double lever s2,

1', rests on the raised stop II on the rear side of the disk r. The stud hereby permanently adjusted in a lower position so that its shoulder-rl does lnot now project inthe path of the projection 7c and hence cannot stop the breech bolt; tho latter is vthus able to fly forward after every shot so that the charging is automatically eli'ccted without the aid of :my special'handle. 0l' course the .si ud wstill lies high enough to be able to act barrel arrester as previously described.

i i ille disk c is provided7 is eifectedbymeans ci the vertically movable safety block u arranged in the rear of the casing g, which block is so formed as to be capable of securlii ing the trigger mechanism as well as the 'also mounted in said cavity.

are 'mounted in the extenihe safety position for which .the rest 3.

breech frame.'A For this purpose the block u is provided at its front part with an ariin u which is long enough to be able to be, when said block is in the operating position, under the projection t2 on the seal' s and thus revent the latter from moving. The b @ick cari-ies a projection on its rear, upper side, which, when the safety stud is in the operating position, projects in the ath of the rojection h3 on the reaiifend o the breech rame 71 that is to say, as shown in Figs. 6 and 7, projects into the cavity h4 of this projection ha, and thus prevents the breech frame from moving backward and also prevents the whole breech system from moving. The adjustment of the block fu. in thev raised or operating position is effected by a guide pin v3, on the rear side of the adjusting disk c, `passing through the slot g3 4formed in the frame into the cavity a3 in thev safety block and thus causing the latterto move with it. In the safety position of the adjusting disk v,

the nose'w3 of the spring plate w, engages with the rest 3 of the disk c, While on the rear side the lever arm ac3 rests'on the flat surface III, whereby the stud ai assumes its lowest posit-ion.

In order to obtain a shockless action of the* weapon when opening as Well as when closing the breech, in spite of the various strains,Av

means are', as described in the introduction, provided for decreasing the ini act of the movable breech casing.

In Figs. '19, 24

and 25, is shown only a part construction of the principle of arranging a buffer p1 solely with the object of takingup the recoil iinpact; the desired purpose'can therefore only eV obtained when the impact isy'weakened during the forward as well as during the: backward motion.' v With this end in view it is necessary to so arrange elastic buiers that the recoil impact of the barrel after firing, and its forward impact when returning to its normal ositi'on, as well as that of the closing breech o lt should be taken u elastically. The special arrangement is s own in Figs. 20, 21, 22 and 23; the breech frame h, as shoWn,`h-as a projection h5 underneath at its fore end for its guidance, orinv other words,

for the guidance of the barrel on the stock backward' and forward,'wh1ch -projectionslides in lateral grooves in the while moving cavity p formed in an extension from the magazine. The barrel-propelling spring. 1s

' wo spring buffers p2 and p sion transversely to its longitudinal axis,

one beingy at the front end and the other at'. th'e rear end of the path of the projection h5.

t e buffer p Thus the projection strikes n when the breech frame recedes and the buffer p3 when it advances, whereby all shocks are effectively taken up in both casesf-{AS shown in Figs. 21 and 22, the projection h5, when theA breech frame is in its foremost mx i eral arrangement ofthej'iing device is such' that the movable hollow'fring pin r. in the breech bolt 7c, is guided backward in the tu bularpart of the minor breech q which carries the iring pin spring, the latter impingi with its fore end against vthe firing pln'hea andwith its rear end against the part g.

The newA arresting device for the firing pin consists, in accordance with the invention as shown at Fig. 24, (the details of which are shown in Figs. 29 to 35), of a Wing e mounted on the side of the. breech bolt, which winglis mountedwith its spindle e? in a corresponding lateral cavity lcs-in the breech bolt, while the wing plate e is provided with an upward pointing nipple e. Wlien the wing is turned 1n, the nipp e thereon projects into a corresponding recess c'dx en a es with arrest or cavity rz which is rovi et in the collarr1 immediately beliin the point ofthe firing pin 1'. Durin the opening and closing of the breech bolt the plate e of the wing e slides on the magazine ledge go" of the stock or frame )piece g. The wing .is

ds back,`as shown in thereby raised. and h o ple e, the firing Fig. 25, by means of its ni pin 1 with its of the breech olt. As soon as the breech bolt is in the locked position the plate e* of the wing is free to pass into the cavit p in the magazine ledge g". The wing is t ereby so turned that, as shown' in Fig. '24', its nipple ez no' longer prevents the firing in from completely advancing, bu't allows t e point of the same to pass in rontiof the front surface of the breech-bolt. In the construction shown the wing is detachably inserted in the corresponding cavity, and is adapted to 'be held in the latter by a spring, shown in Figs.` 29 and 35, mounted in the side of the breech bolt, in order to .prevent the wing'from accidentally falling out when the parts are being disassembled. v Y l 'It will be obviousf.f"that many features of the'present invention` can be used in connection with the invention set forth in my application No. 372,109. The trigger mechanism (Figs. Sand 10) is so arrangedthat the wea )on can only be iired when the breech is loc ed and after the breech frame has advanced, means also being provided for the disconnection of the sear and trigger catch, thus freeing the latter after iiring so that it shall catch the firing pin without fail in the nextA operation of the breech. For this purpose t e trigger lcatch u. lixeil to the trl ger, has its upper en formedV as a hook; t e sear s has a projection in the. breech bolt lc and oint behin( the front surface.

' collide with the t on its rear end, over which the hook w of the catch 'projects'when the partsare in the position for firing. In the osition ready for shooting, the'hook w andpthe projection t lie. the one above the other, so that, when the triggeris pulled, the sar is pulled down and consequently the firing. in released. After the trigger has been pul ed and the shot has been fired, the hook w is pushed sidewise by l"the bar il, when'the breech frame, with the minor` breech,` is sliding back, so' that the sear, that 1s to say, its projectiony t, is quite free of the hook wo; the s ear is thus able to catch ,the firing pin withoutbeing checked when the next opening and closing of the breech takes place. For facility of disassembling, the arm uois lower end, so t at, at th'e relative position, a projection or shoulder c is formed, by means of which the arm can be pushed into a corre-v `spending slot `z1 in the trigger. The itting is effected by the lower end of thehook beingl suspendedby a pin 4in the trigger and then turned until the' shoulder nulles behind the wall4 of the slot- 2. f

The spring-iniiuenced ejector f, (Figs. 8, 10, 37,l 38 and 39), oscillating in a recess in the magasine ledge, has an open topped hoop f 3 formed at its front part, the two side pieces of which are divided y a slotf and are able to move toward each other. The front side iecehas the rearwardly slantin point f1 on 1ts upper end, against which t e cartridge base im inges when the breech bolt flies back. he front art of theejector, being the spring hoop. 3, permits the frontv part with the point f1, to yield backward .when

provided with a recess at its struck, whereb the force of impact is rliminishedl andv a being damaged and consequently jamming is entirely eliminated. The amount of movement 4in the hoop is suflicient' to' leave play between the two legs 1ri1pact;` they consequent] never touch each other, and assure un'dei' a l conditions am le elasticity for the impact of lthe cartri ge `.ase. The rear leg has alateral shoulder-f2 which, rests against the relative lower surface of .the breech bolt and thus holds the ejector infpositi'on. This shoulder f2 lies at the side of the longitudinal center slot, under l possibility of the cartridge for the strongest v the fullpart of thev breech bolt, see Figs. 14 and 18, when the latter recedes'and advances, I

whereby theejector is held pressed down, so that its point f 1 does not projectinto the slot in the breech bolt breech bolt locking spring z within the breech bolt bore. The iront end ofthe breech bolt has a lateral recess, into which 'the nshoulder f2 can pass when the breech bolt has passed into its rearmost posi* tion and the front of the same is over the e'ector, in order that the shoulder may vbe 1n t ,e position to swing up into the position for action, see Fig, 10.

and consequently cannot The connection between theextractor and lts shank or leaf is secured in the usual mann er by a 'dove-tail shaped joint on thc topof the breech bolt-1E, while the fore end, 7" ot the same having thel K proj ectio "2 is, however,

not free on the'breec boltQl is inclosed by being surrounded by 'tl-ie'l head of the breech In' the construction shown the end 7" bolt.

"of the extractor is insides recess r, which is 1 0 closed at the upper part by a' projection kf on the breech boltl serving the purpose of a handle. "In consequence of the extractorv being in this inclosedicavity, an exact guide forthe 4same is obtained and the slipping on one side or jumping backward of the cartridge is preventec As regards, finally, the adjustable auxiliary magazine m", (Figs. 1, 26, 27 and 28), the same has a top plate lml which, of course is provided with an aperture for the passage oi' the cartridges, and corresponds in outer shape to the base plate of the stationary riiie n iagazinev wi. This 'plate is provided at either end with the hooks m2 and m3, the iirst 25 of which (m2) engages with a corresponding recess in the rear end ofthe. magazine., while the other hook (m3) engages with asimi'larly Y f directed .groove in the front of'tlje magazine in exactly the saine manner as the base plate 30 oi' the stationary magazine is'secured. The

magazine, or in other words, the adjusting' plate,is secured similarly to the base plate, namely; by a vertical spring actuated lock bolt iii a bore in the front side of the magazine, which bolt engages with acci-responding hole in' the hook m and thus secures the adjusting plate against lateral movement. The stroke of this bolt is limited. The auxiliary magazine mois fixed in position, after 40 the base plate of the riiie magazine box 'm is removed, in exactl 4the same manner as the latter base plate. 7Vhen the auxiliary magazine is to be detached, the pointof the boltengaging with the projection vfr'na'is pushed up and .the ma azine and plate pushed back ward'uiitilt e hooks are free ol' the grooves, whereupon the magazine can be readily dc- .tached downward. Spring lips l, connected to one another, are provided, which are adapted to prevent the cartridges from passing out of the magazine oriiice whenjthe magazine is taken fl'. In this particular` case the lips are carried by aU-shaped plate pivoted by the pivots Z to the sides ofthe magazine, and the rear part` ol' whichl is .formed with ahandle Z2 for the purpose? of .putting the lips in or out 0l action. l Vallen the magazine is adjusted, as shown vin l` ig. 1.,

thelips, of course, are out oi' action, the liajj- GQ dle and plate being pushed downwfor this purpose. As soon as the magazine is taken ofi', the plate carrying the lips is pushed up into the position shown in Figs. 26 to 28, the lips being then in Iposition to prevent the ear-- 55 .tridges from leaving the magazine.I 1t is obvious that one is not n'iietly confined to the means for securing the loose pla-te; any'therf securing means for the magazine might be"'"` providedrunderneath or at the side of the magazine casing. As previously mentioned in the introduction, no alterationsinthe arrangement ;ind securing means of the staf' tionaiy magazine are necessary for the use oi" the auxiliary magazine, as the latter, which hasa ca acityfor a large-number of cartridges, 10,15 or 25),corresponds with respect to breadth and the feeding device to t estationary magazine.

What I claim as'my invention and desire to secure by Letters Patent is:

1. In'a iire arm, the combination of a breech .bolt movable longitudinally and an oscillating locking bolt, said locking bolt being U-shaped-so as to receive the brecchbolt within it as the breech' bolt moves backwardly, said locking bolt having at its forward end means for engaging the breech bolt to lock the latter in place. l 2. In a fire arm, t e combination of an os- J cill'ating U-shaped locking' holt, mounted in the barrel extension, said U-shaned bolt l'iav'- ing an u per cross piece adapted to form -a support or the breech bolt, and having arms having bearing surfaces b" at their-front,

ends, grooves bx ruiming lengthwise of sa bolt, said breech bolt having pro ections kx for co-actiiig with said grooves, w ereby the breech bolt is secured in tlie unlocking posi- I iio' to arrest the barrel alone, and safety means,

adapted to hold the barrel and trivger-mech- 1 he opening anisin in fixed p'sition whereby t of the breech and the firing is prevented.
