To all whom 'it may concern:

Be itrknown that I, CHARLES D. LovELACE, a citizen of the United States of America, residing in Fort Worth, in the county of Tarrant and State of Texas, have invented certain new and useful Improvements in Automatic Guns, of which the following is a full, clear, and exact description, reference being had to the accompanying .drawings, forming part of this speciication.

My invention relates to that character of automatic guns inl lwhich the force of the recoil of the` n barrels is utilized as a medium yfor feeilng 'the cartridges to the barrels and for the actuation of the 'mechanism by which .the empty cartridge shells are Aejected from the guns subsequent to each firing action and previous to the delivery ofthe vnext cartridge tol the gun barrel.

FigureI is aside elevation of my gun.

Fig. XXI is a horizontal lo itudinal 'section taken on' line XXI-X I, Fig. XX.

Fig. XXII is 'a longitudinal lvertical section taken through the receiver and the parts adjoining it with the gun barrel shown in for- .ward position, the breech block andA hammer in the rear positions assumed when an empty cartridge shell is being ejected and a fresh cartridge isl being carried toward the :barrel previous to the vadvance of the breech block. Fig. XXIII is a longitudinal horizontal sec.- tion taken through the receiver above vthe guides on which 'the breech block and hammer travel. Figs. XXIV, XXV, and XXVI are diagrammatical views illustrating the lpositions assumed by the gun barrel, the 'breech block and the hammer when the barrel has recoiled; when the barrel has moved forwardly and thebreech block and hammer are restrained in their rear positions; and when the breech block has advancedv to the barrel and the hammer has partially advanced previous to its 'full release for comV llete advance tov the breech block. Fi .'XlXVIIis afcrosssection taken on line X VII-XXVII, Fig. XX.

In vthe accompanying drawlngs: A desig- -nates the butt stock of my gun, B the re- Aau forward end of the receiver and "provided at l its, breech end with side extensions c that contain pockets-c (see Figs. 'IX,'XVIII and XX to XXII inclusive). The barrel Q `1s provided at its lower side withalug of', see Figs. vII and X.

D is the `fore-stock located beneath the gun i barrel "and =in which the lug 0*1s` operable.

Thebarrel C -of my gun isadapted to recoil partially xinto the receiver B when the gun 1s red, due tothe expansion that takes `c. 'I is spring is backed by a buffer or auxiliary spring 3 of greater strength than the spring 2.A These springs serve to carry the barrel to its forward position subsequent to each recoil of the barrel. 4 is a cushion spring interposed between the forward end of the lug 0 and the enlarged forward end of the rod 1 and which serves to prevent shock when the barrel moves forwardly. The spring 4 is-made interchangeable with and weaker than the spring 3 so that in guns with varying charges of ammunition (as shot guns) the spring 4 may take the place of the spring 3 and still' allow lighter charges to be used than `which it takes to operate the spring 3. A

Referring now to the receiver B, 5 and 6 designate guides at the interior of the receiver, andat its sides, upon which the bar-l rel extension arms, breech block and hammer of the gunrride.

7 is the breech block adapted to travel on the

guides

5 and 6. The forward portion of the breech blockl is of less diameter than the diameter of its rear portion, and which is adapted to enter into a position between the side extensionarms o of the gun barrel, as seen most clearly in Fi IX and XXI; The breech block is provlded with a rear chamber 8 and a forward chamber 9, and a front firing pin hole 10.

11 is a plunger loosely seated in the rear chamber 8 and provided with a head 12 that carries rearwardly extending arms 13 between which is a space adapted to receive a member to be hereinafter mentioned.

14 is-a return spring located in the rear chamber 8 in front of the head of the plunger 11 and by which said plunger is moved rearwardly after it has been moved in a forward directiont 15 are locking keys loosely mounted in the breech block and extending above and beneath the forward end of the plunger 11, as seen in Figs. VIII, IX and XVIII. These locking keys are provided at their outer edgesl with lugs'or studs 16 which are adapted to enter the ockets c inthe barrel extension arms c or the pu breech block to the barrel C and the keys contain inclined slots 17 extending laterally therein-and in whichis tted a shift in 18 thatis carried by the plunder 11. T e slot 17 in one of the locking llreys extends toward oneside of the'gun while the slot in oseV of locking the the other plate extends toward the opposite' side of the gun, and consequently the shift pin 18 acts to mo've one of the keys to and from one of the barrel extension arms and the other key to and from the other of said extension arms. In so far,- at this point, as the action of the locking keys -15 is concerned, it is'suflicient to note that when the lugs 16 of these keys are in position inthe pockets of the barrel extension arms to lockthe breech block to the barrel and the breech block is to be released from the barrel, the following operation takes place. Upon a forward movement of the plunger 11 the shift pin 18, by riding in the inclined slots inthe locking keys in a forward direction causes each key to be moved inwardly in the breech block so that '1t will be withdrawn from the barrel extension arm previously engaged by it, thus freeing the breech block and barrel from each other .for separation. Then, when the plun er 11 is relieved to be returned to its norma position by the spring 14 after the breech block has become separated from thebarrel, the shift pin 18 acts to return the locking keys to their former positions in order that they may a ain move into locking engagement with .t e barrel extension arms when the barrel and breech block are again assembled.

19 designates a ring pin that extends longitudinally through the breech block 7 being in part mounted in the plunger 11 through which it extends and in part seated in the firing pin aperture 10 at the forward end of the breech block. The ring slotted, as seen in Figs. VIII and I to provide for the passale therethrough of the shift pin 18 by whic are actuated.

20 is an extractor arm carried by the breech block and having a hook fin ger 20 at its forward end which extends downwardly at the forward end of the breech block and is adapted to enga e the rim flanges of cartridge shells for t e purpose of withdraw- -ing the shells of spent cartridges from, the

gun barrel. 21 is an ejector slide loosely ositioned 1n the forward chamber 9 of the Vreech block and extending through the forward end of' pressure spring 22 which rests at its rear. end against the forward end of the plun er 11 an which acts` when the spent cartri ge shell is withdrawnfrom the gun barrel and the breech block is separated from the gun barrel to throwthe c]ector slide forwardly and causeit to lip the shell upwardly and .discharge it through the opening b in the 'mis'y the locking keys 15 receiver B. This action occurs when the plunger 11 is in a forward position and consequently when thespring 22 is rendered more powerful than normally, duewto its bein held in a partiallycompressed conditiony said plunger.

The` breech block 7 is carried rearwardly with the barrel C each time that 'al recoil movement of said barrel occurs and" the forward .movement of the breech block 'is y thereafteroccasioned by the following means.

,23. is a push rod (see Figs. II, VIII., IX and XVII) which is pivotally connected at its forward end lto lugs 7 (see Fig. XIII) at the b'ott-om'of the breech block. This push rod is provided intermediate of its ends with a slot 24 and its rear end' is ttedto va seat member 25 located at the forward end of a propeller spring 26 l in the butt stock A.

Eachy time that the breech block moves rear! wardly thepropeller lspring 26 is placed under tension by the direction off force from the push rod 23 and when the breech block is to a'gain move forwardly saidpush spring serves to impart the desired movement to the breech block.

- 27 designates the hammer of the gun (see Figs. II, VIII, IX, XVI and XX to XXII inclusive). This hammer` is located within the 'receiver B and is adapted to travel to `and fro longitudinally of the receiver upon the guides 5 'and 6. The hammer has `a forwardly projecting arm 27 The hammer i '(s'ee Figs. IX, XVI an-d XXI) is provided with apertures 28 through which the Lside arms ofthe plunger 11 in the .breech block .are adapted to pass and intermediate of theseA apertures is a striker member 29 that is adapted to strike the rear end of the tiring pin 19 in, the act of tiring the gun. The apertures 28 in the hammer providel for the passage of the side arms 13 ofthe plunger 11in the breech block through the hammer for impact against the rear vprall b of the receiver B. It i's well to here mention that f when the gun barrel reooils, and the breech block and hammer recede with said barrel after the gun is fired, the barrel is unlocked from the breech blockato return to its normal forward position'while the breech block is temporarily restrained 1n al rear position.

vThe unlocking of thelvbarrel from the breech block is occasioned by thearms 13 of the.'

plunger 11 striking against the lrear wall b of the. receiver` thus causing the yplunger to i move Aforwardly in the breech block, and ac'tuate` the lockingkeys 15.with the result of withdrawing them from the extensions c lof the barrel",` 'In'the-act of firing theL gun the'hammerr is propelled forwardly by a propellingvspring 30 located in the stock A andV a pusher"rod`31 that is pivotally connected to `.the hammer and rests Vat its rear end in a seat member, 32 fitted to the forward yendfof said spring (see-FigsfIX and XXII) Referring-next to themeans whereby the breech block and hammer are automatically controlled through the medium of the gun` barrel, designates a controlling bar (see i Figs. VIII, and XXIV to XXVI inclusive), and which is located beneath the guide 5 in thereceiver B upon which the siderextensions c of the gun barrel, the breech block and the hammer ride. L.This controlling bar is pivotally connected at its forward end to the adjacent side wall of the receiver by. ag

screw or pin '34 that passes through a `ver-v tical slot 35 in the bar, uthereby providing not only for vertical swinging lmovement of the controlling bar but also for direct verticalv movement ofthe forward end of the bar. At the rear end of the controllingbar is a verticalhammer receiving catch arm 36 i located alongside of the Guide 5 and the upper edge of which is inclined downwardly and forwardly. v At a point forward from the hammer receiving arm 3G is a vertical breech block receiving catch arm 37 which extends through an opening in the guide 5l and the upper edge of which is inclined downwardly and forwardly.'

' 38 1s a rear tr1p arm extending upwardly from the controlling bar-at a point in front-- of the breech block catch arm 37 and occupies a position alongside of the guide 5. The upper edge of the trip arm 3S is inclined upwardly and forwardly. Y

39 is a forward trip arm carried by the -controlling bar and extending` through au opening in the guide 5 in alinement with the opening through which the Abreech block catch arm 37 extends. The upper edge of the forward trip arm 39 is inclined upwardly and forwardly similarly to the up per edge of the rear trip arm k38.

The controlling bar 33 is yieldingly supported for the service it is to perform by a spring 10 within the receiver B and which is most clearly seen i-n'Fig. XXII.

The side extension c of the gun barrel which rides upon the guide 5 when thc breech end of the barrel rides to and fro` in the receiver B is provided at its lower edge with a rear beveled face c1 and a forward beveled face c2, as seen most clearly in Figs. XXIVy and XXV, and which inclines ico are. adapted to coperate with the forward in a lower position against theaction of the lift spring 40, due to the breech block bearing against the upper end of the rear trip arm 38 as illustrated in Fig. 'XXVI, and

5 consequentlythere is no interference offered by the controlling bar to the rearward movement of the vsaid breech block. Upon the gun being fired and recoil of the barrel C taking place, the rear portion of said barrel,

the breech block and the hammer (it being understood that the hammer has been released and moved forwardly in 'the act of ring the gun) move rearwardly into the positions in which the parts appear in Figs.

XX, XXI and XXIV, and the controlling barv 33l is elevated by the. sprihg 40 so that it lies in a horizontal position immediately beneath the guide 5. While the controlling bar is in the position just mentioned the 2Q catch arm 36 is present in front of the hammer 27 and acts to restrain the hammer from forward movement. The catch arm 37 is in front 'of the breech block and acts to restrain it from forward movement. The

gun barrel having been freed from the breech block by the disengagement `of the lockingkeys 15 from the side extensions 4of the barrel, is then moved forwardly to a recovered position under the influence of the 3Q recovery spring 2, and as it moves in this tirely through the side extension of the barrel. In striking the forward trip arm 39 the side barrel extension acts to depress the forward end of the controlling bar from the A position seen in Fig. XXIV tothe position .40 seen in Fig. XXV with the result of causing the catch arm 37 in front of the breech "block to be\lowered from the position inwhich it acts to restrain the breech block, The breech block is then forced forwardly to the barrel underthe infiuence of its actuating spring 26 to become again locked to the side extensions of said barrel. be here stated that ,the Vshellvof the spent cartridge is withdrawnby the breech block from the barrel when the. barrel moves forwardly and thebreech block is temporarily restrained from movement and is ejected from the receiver of the' gun in the .manner previously explained. During the ferward movement of the 'breech'block itfstrikesagainst the rear trip arm 38, and byl sodomg acts to cause the controlling bar tobe 'lowered from the position seen in Fig. XXV

to the position seen in Fig. XXVI, with the result of withdrawing the rear catch arm 36 from restraining position in front of ,the hammerV 27. Ihe hammer is therefore vfreed to move forwardly into the osition seen'in iigevn, Ix and xx te bemmpo- It should the s'upp emental' sear piece is pivotally .con-

rarily held at that position by trigger conltrolled means to be next described.

ates the linger trigger pivotally' mediate of its ends at 45 to the side wall of the receiver' B that is occupied by the guide 5. At the rear of .the pivotal point of this lever is a stud 46 that rests upon the stem 43 of the trigger arm, thereby providing for the rear arm ofthe lever 44 being elevated and the forward arm of said lever being lowered when the trigger is pulled rearwardly.I

47 is a spring attached to the receiver B .and bearing against the lever 44. This spring acts normally 'to so hold the lever 44 that its forward end will be in an elevated position and its stud 46 will act to hold the `has been pulled rearwardly.

48 is a main sear piecelpivoted to the forward arm of the lever 44 and vertically positioned in a guide 49 at the inside face of the side wall of the receiver occupied by the guide 5.'. The sear piece 48 is beveled at its upper end and it extends through the guide 5 in thev path oftravel' of the' hammer 27 and its forwardly projecting arm 27 When the breech block and the hammer recede after the gun is fired the hammer moves rearwardly past the sear piece 48 and is caught by the catch arm 36 of the controlling bar 33 in the manner previouslyexlalned, and after said hammer is released y the lowering of the catch afm 36, as previously explained, the hammer moves forwardly to the position illustrated in Figs.

VIII, IX and XXVI, to be restrained from further movement until the trigger 41 is again pulled with the result of lowering the searpiece 48 from a position in front of the hammer carried arm 27.

50 isa supplemental scar piece pivoted to the rear arm of the lever 44 and extending vertically from its connection with said lever to the guide 5 through which it is adapted to operate. This sup lemental sear plece is elevated each time t at the trigger is pulled and the main sear piece 4 8 is lowered, and it has the utility of a ard that will arrest forward movement o the hammer in the ,event of.y the user A`of the .gun involuntarily keepin-g hisA finger upon the trigger to exert apull thereupon with the result of the main sear 'piece being lowered when the userof n is not ready to ire the gun. The

nected to the lever 44 in orderthatit may be thrown rearwardly out of operative position when the gun is to be used for automatic shooting, one shot after another, until the vuser releases the trigger 41, thereby permit.-

Y 51, see Fig. XXII that has slot and-pinconnection with ,the sear piece and is provided with-.a button stem 52 that extends through a slotfb-g' in the receiver B, in vwhich it may be moved rearwardly for the purpose of throwing thesupplemental sear piece out of operative position., The button stem 52 is held in a suitable notch at the bottom of the slot b'by a Spring 53. l 'c 454 is a safety catch slidably tted'in the receiver B in front ofthe trigger 41V and held from accidental movement by a spring arm 55. This catch is adapted to b e moved rearwardly into engagement with thevtrigger when it is desired to prevent operation ofthe trigger.` v f Referring n ow to the magazine of the gun which is located in the stock A, 56 designates vthe magazine housing, subdivided by a vertical partition 57 into a rear compartment 58 and a forward compartment 59. In the compartment 58 is a pressure spring 60' and in compartment 59 isa pressure `sprin0', 6l,both of said springs having the utility of exerting downward pressure upon the cartridges that are introduced into the compartments in which the springs are. present. One of the side walls of the ,magazine housing is provideduwith spring tongues 62 cut from the wall and extending inwardly at the bottom of the compartment, -as seenmost clearly inv Figs. VI and XV. These tongues. serve as yielding supports for the lowerrnost cartridges in the magazine compartments. At

the bottom of the stock A and beneath the magazine housing compartments are doors 63 preferablyhinged to'` the stock and which control` openings through which the cartridges may be introduced infilling the conipartments 58` and 59 and the runway 65.

' vThe cartridges may, however, where desired,

he introduced into the butt-stock through-an opening 'a in the' buttofthe stock that is controlled by a door 64.

65 designates a cartridge runwaythat is vlocated in the stoekA and extends forwardly from the magazine housing. Thecartridge runway' is seen in Figs. II, VII, VIII, XI, XII,.XVI and XVII, but is most clearly 'illustrated'7 in Figs. XI and XII, in which it` appears` in detail..

f'arerestralning dogs securedto one wall of the runway. '.Thesedogs are preferably -in the shape of spring arms rlocated at the exterior of the runway and extending through openinos in the wall of the runway i so as toxbe yintlie path of travel"of the cartridgesthat are conducted through the runway. The dogs serve as means for prevent# ing rearward movement -of the cartridges.

67 desi nates a carrier bar located rexterior of tie runway 65 and the magazine housing 56, in suitable guides 68 attached to the runway and magazine walls, see Figs. and VII. The rear portion ofthis carrier bar is located alongside of the wallof the runway opposite to that at which the dogs 66 are located and the carrier bar is bent upwardly back of its forward end to t-he Itop 4of therunway and has a front extension 67 that operates in guides 69 at the top of y the runway, as seen most clearly in Figs. V and XI.

'(0 are carrier dogs attached to the carrier bar 67 and its extension and operable in the magazine housing and runway 65 into which they extend to engage the cartridges to move them forwardly in the runway.

7l'is apusher linger extending forwardly I from the forward* end of the carrier bar extension 67', see Fig. VIII.

The bottom of lthe forward portion of the cartridge runway 65 is cut out and attached tothe bottom of said runway is a spring rest plate 72 onto which the cartridges are delivered into a position beneath the breech block when it is in its forward position and pass over v p located above and p allowed to operate through the slot in said rest plate.

During the operationof my gun, the cartridges descend `from

the'magazine compartments

58 and 59 and into positions in front avv front restraining' dog 7 3 that is` of -the carrier pawls 7() that are beneath said l compartmentsin a mannento provide for the cartridges being conducted m single file through the runway 65, the cartridges in the rear compartment 5S being those `first deliyered. `To provide for the` automatic actuation of the' cartridge carrier comprisingthe carrier bar 6 7, its extension `67 and `the pawls 70, I furnish connection between the 'Y "carrier bar and the push rod 23that actuates the breech block of the gun. This connection is preferably furnished by a link 74 pivotally attached t0 the extension of the carrier bar and ivoted to the breech block push rod at .the s ot 24 in said rod. Each time that the breech block is moved rearwardly upon the recoil of the gun barrel, the link 74 Vis carried rearwardly with the breech block, thereby causing the entire series .of the `carrier "pawls of the carrier bar ,to be moved rearwardly `and engage cartridges that have been located at the rear ofthe pawls., Then, as the breech block moves tO its forward position the 'cartridgeA Vcarrier members are advanced and the cartridges are moved by the pawls 70a single step in a forward ,direction. The carrier members are so disposed that a: cartridge is always located on the spring rest plate 7-2 previous to the rearward movement 'of the breech block, and immediately 'upon said breech block moving rearwardly the cartridge on this rest plate 1s relieved from pressure previously exerted up,on it bythe breech block, .and is elevated by the rest plate into the positions shown in Fig. XXII. The breech block immediately thereafter moves into engagement .with the head of the cartridge, an engagement that is rendered more perfect by the provision of spurs 7 a at the forward end and bottom of the breech block (see Figs. XIII, XIX and XXII) and the cartridge is carried by the breech block into the un barrel.

I provide in my gun means w ereby the breech block may be restrained in a rear position when the last shell that has beenv loaded into the gun has been red and this means comprises the following parts: 75 is a locking arm ivoted to one of the side walls ofthe recelver B through the medium of lugs 76 secured to said wall. This lockingarm is seen in Figs. VIII, XVI, XVII, XXII, andXXIII, and `,it occupies 'a vertical position within the `'receiver alonvside of theA rest plate 72 toward which it is adapt-- ed to be moved by a spring 77. 78 is a retracting lever that is horizontally positioned in the receiver` and is'pivotally mounted in lugs 79. The rear free end of this retracting leveroccupies a position alongside of the.

locking

arm

7,5, see Figs. VIII and XXII, and the forward arm of the lever is provided with a button 80 that extends ,through the adjacent side wall ofthe receiver in order that the retracting lever may be operated by pressure upon said button to throw the lockmg arm outwardly, or in a direction toward theadjacent wall of the receiver and away from the rest plate 72. When the breech block of the gun is moved forwardly to becomelocked to the gun barrel, a rib 7" at the bottom of the breech block and extending longitudinally thereof acts upon the locking arm to move it laterally butthis condition is only possible when a cartridge is present upon the rest plate 72. When the last cartridge 1n the magazine of the gun has been delivered first onto the rest plate and thentransferred therefrom to the un barrel to be exploded, and the breech lock recedes subsequent to the explosion of the las t cartridge, the locking armisinoved by the spring 77 into a posltion in front of the breech b ock. As a consequence, the breechblock is held in its-rear position, thereby enabling ',t-he user of the gun to reload itV without the necessity of retracting the breech block for the introduction ofa cartridge into-the gun barrel in connection-.with the refilling of the vlma zine. `While the breechF block' is'held bac the o erator may open the forward 'door63A an j insert one cartrid e at a time into 'the runway-65., When t e firstcartridge passes ont-o the rest plate 72 said rest plate will be raised upwardly and retract the locking arm 75, allowing the breech block to carry the cartridge into the barrel, and the gun is then ready to fire.

I will next describe the means by which the breech block is manually released from the barrel extension arms and drawn rearwardly when the barrel and breechv block are in forward positions and it is desired to separate the breech block from the barrel to permit loading of the gun.

81 is apull lever that is pivotd at 82 to the breech' block, see Fig. XX. This pull lever is operable in a vertical slot B in the receiver and is adapted'to move longitudinally of the receiver when the breech 'block `moves forwardly and rearwardly in the use of the gun. i

v83 is a linger arm that is pivoted to the lower end of the pull lever sothat it may be swungoutwardly and upwardly when the pull lever is drawn rearwardly to bring its lower end to a position exterior of the slot The object 1n providing the linger arm 83, attached to the pull lever as stated, is to allow the operator to gain a better hold upon the pull lever for the actuation thereof. The pulllever 81 is provided at itsupper vend lwith a hook 84 that normally seats against a button 85 located at the rear of a spring 8G. The spring 86 and the button 85 are located in the breech block and these parts serve tov normally hold the pull lever 1n the position shown in Fig. XX in order that it will ride` to and fro within the receiver B. The hook 84 of the pull lever is adapted to engage a stud l1 projecting from the plun er 11 in the breech block, see' Figs. IX, XX and XXI which is bperable in a slot 7c in the breech block. When the gun barrel and breech block are in forward l positions and it is desired'to unlock the breechblock from the barrel and retract it from the barrel, the pull lever is moved rearwardly by first drawing the fin er arm 83 downwardly out of the slot B- in the receiver, then swinging saidarm upwardly -and exerting a pull rearwardly uponthe arm and the lower end of the pull leverl 81 to move the hook 84 of said lever forwardly. When the pull lever is'moved as just explained, its hook is carried into engagement with the stud 11 of the'plunger 11 and as a consequence said plunger is moved forwardly to cause -itto actuate the locking keys, 15 and vdisengage'said keys from thebarrel extension arms c. Then, upon a continued pull uponA the linger arm 83, the breech block is drawn rearwardly until it becomes engaged by the catch arm 37 of the controllm bar 33 or the locking arm 75'to be held 1n a retracted position.

' For the purpose of facilitating the packing of the parts of the gun when the gun is parts as follows: The rod 1 of the barrel re-` covery parts is provided at its rear end with a screw threaded stem 1 that` is adapted to `be seated in a nipple shaped member B2 at the front end of the receiver for the purpose of connectin the `rod to the receiver. therod 1 -ad]acent toits stem 1 is a screw hole la and at the opposite or forward endY of the rod is a screw hole 1*. 87 is a retaining screw that is seated in the chambered fore-stock D and which enters into the screw hole 1b in the rod 1 when said rod is in position for service in the gun. The rod 1 is provided with a chamber '1c extending inwardly from itsy forward' end and contains a notch l-d which leads .outwardly from said v chamber. 1 is a cross pin mounted lin the forward end oitk therod and in juxtaposition to the notch 1d. 88 is a slotted turn bar that is fitted to the :cross pin le and is adapted to occupy the chamber 1n the rod when the gun is 1n use as seen in Fig. X. When the gun f is to be taken down the vretaining screw 87 is lirst withdrawn from the fore-stock and from its seat in the screw hole 1" in the rod 1 and the fore-stock D is then separated from the barrel of the gun and from the nip-k ple shaped member B2 atA the front end of the receiver'. The turn bar 88 is then withdrawn from the rod 1 and manipulated in a circular path for the purpose of unscrewing to disconnect the rod from the receiver. The rod may then be withdrawn through the lug c carried bythe gun barrel and the recovery spring and buffer spring are stripped Ycupies the cavity d at the `forward end of said fore-stock. The barrel and fore-stock will be assembled. The retaining screw 87 is then inserted through the fore-stock and entered into the screw hole 1a in the rod 1 which screw hole is at this time in registration 'with ythe hole in the fore-stock through which the retaining screw passes. When theV parts have been arranged'in the fore-stock as explained, 1the rod 1 and the springs thereon are securely held in the fore-stock in which connection it is to be noted that the springs are prevented from escaping' at the rear end of' the fore-stock, due to the existence of the head at the front end of the rod 1 against which the cushion spring 4 rests.
