Referring to the re'i"erence letters' and'flgures in' a moreparticular description, 20 in-` dicates the barrel Whieh is screw-threaded into the forward -endof the'barrel portion v50A 21 of the .frame,`and. 22 is the butt` stock --Which is 'securedbymeans lof tangs to the vstockportion 2 8I ofthe frame or receiver.

The barrel, portion 21 of the lframe consists plate'21fb, together .With an enlarged or thickenedjend 'atV the front', as indicated'at 21?,

which receives the' rea-r screw-threaded end of the'barrel'a's Well-as the .rear end-of thetubular magazine 24 andl against the front 70 face of ,Whichis fitted the rear end of the forestock 25. The stock portion of the fra-me consists in the main of a side Wall 23?, a bottomf'plate'23 and a thickened Wallv at 23c from Which the-tang's carrying the' stock 75 extend vandgvvhichaffords a. shoulder at 26 against which the rear endoi' the -frame part 21. is adapted to tit. The for-Ward end of thel frame part' '23 is provided With a socket at 27'adapted to receive a projection 80 -28 provided on the part' 21?. This'sooket and projection at the front end in connection with the screw, 29 toward the rear serves -to secure lthe frame4 parts 21 and 23 together, and When vsecured together they 85 forma chamber to receive the operative .mechanism of the fire arm or the major portion thereof.

The breech block 30 is arranged to recipe roca-te` longitudinally with reference fto' the 90 -b'arrel in the' space immediately tothe rear of t-he barrel under the top plate21b and conined'betiveen the sideplates 21'a and -23". The rear end of the breech block is provided 4with a pin or roller 31, which is received in 95' i and'isunovable along'the longitudinally-ar! ranged slotl 32provided in the frame wall 21a." The forward end of the breech block is provided with downwardly` extendingprojection 30t Which contains lthe rearwardly 100 The inertia piece is moved toward it:s-for 1 10 ward'position and the breech block is opl-- eratedA and closed by the spring 2 7 coiled.

' about the tubular magazine which serves as frame.

a ,guide therefor and confined between the forward Jface ofthe part- 21 and the rear face of the inertia piece'. The extension or connecting part 35 of the inertia piece is arranged to operate in a groove or slideway 38 in the inner facevof the wall 21a of the This arrangementenablesthepro1 jection 34; to besupportedeffectively. The' breech block 30 is provided with a hook extractor el() 4pivotally mounted and held in cartridge engaging position by a spring 4l. The head of the cartridge as X is adapted to'bc gripped between the extractor ll0 on* the one side ofthe face of the breech block; and the hooked flange-42 on the opposite side. The ejector 45 is mounted in a removable base-plate 46 let into the wall 23 of the frame, and the ejector is adapted to be received in, and allowed to come in engagement 'with the cartridge head by the provision of, the groove 47 in -one side of the block.' In the breech block is also mounted the firing pin 50, which extends longitudinally through the length' ofthe' block and is reduced at its 'forwardlend to opera-te through a: small opening, as shownv in Figs. l and V2, to engage a cartridge While,

' it projects at the rear end to adapt-ittobe struck by the hammer. The springk 51 is providedywhich serves to retract.' the firing pm. l l

The hammer 52 is p1votally mounted either directly on the frame holding screw 29, or on a sleeve surrounding this screw, and is'adapted when the block is 'in closedposition to strike the rear end of the firing pin as shown in Fig. 1.`The hammer 52 is operatedby a spring'53 coiled around a sliding or reciprocating'stem 54, which, at one end, is provided with a conical head 55 atfordin a shoulder against which one end of the spr1ng'54 bears, and a nose or point engaging in a socket in lthe lower end of thel hammer 52. The for- Ward end of the spindle 54; is arranged to slide freely in an opening rovided 1n theA front end of the part 23, an the 4spring and spindle are're'ceived in a recess or socket- 56 in which they are well housed and still easily accessible and assembled lor removed,

Pivotally mounted at 57 .on the hammer 52 is the hammer pawl ,58. The part 58'has only a limited swinging movementfo'n the pivot 57 `.with reference to the, hammer and is held to `ltsopen position by a spring 59. The part 58,

thecatch's l oulders onthe trigger 62, which 'The arm may also be rea stop 72 pivotally mounted on the receiver part 23 at The cartridge stop is operated to its elevated ;or upxper' position, as shown in Figs. l and 15, by t e spring 74, and is adapted to be depressed by thebr'cech bolt engaging with projection 72". The cartridge stop hasl a cartridge vengaging shoulder 72a. The cartridges areffed back against the cartridge stop 7 2 by a. ma azine spring 7 5, together with a magazine ollower 76.

On the inertia piece extension bar 35 there may vbe provided a knob or handle SO, by means of which 'theL inertia piece and` block may be manually operated, there being provided, of course, for a suitable distance a slot through the wall 21a to permit the reciprocal movement of this knobin Vconnection withV the inertiapiece.

It is' obvious that the `can be. readily taken down by loosening t e thumb-screw 29, when the parts ofthe frame are separable `and the workin parts of the lire arm made accessible and argely readily removed for cleaning, inspection or replacing of parts. ily put to ether and secured simply by operating the t umbd screw 29.- l

When properly `assembled for use,` the magazine may be loaded from the-front end inl any" of "the 4usual nianners 'employed in connection with tubular magazines. Theollow'er and follower -spring will move the cartridges backwardly Vuntil the` rearmost cartridge becomes caught. onthe cartridge' 'stop shoulder 4'72. For the purpose of get'- ting the n into shooting condition, the operator w1 l operate the breech block'30 once by means of drawing back on the knob'SO. This movement compresses thel recoil sp1-ing 37, slides back the breech block until itcom'es to'a lstop against the end of the slot 32 or the shoulder mon the frame, when the front end of the breech bolt is swung downwardly by lio the action of thepin orprojection 34 in the camfslot '83. In its downward swinging 'movement the breech block first strikes the projection 72b on the top of the cartridge sto su ciently to throwtheA stop shoulder 72* out of operative position, when the rearmost tartridgey is Vimmediately moved backwardly until it strikes the breech block. The con# 'tinued 'swinging-downward movement of the.

Followingthe upward swinging movement y -of the forward end of the breech block thev 1'5 continued operation of thel `spring 37 then 'closes the breech 'block .and introduces fue cartridgeinto the cartridge chamber of the barrel. l 'VVhenthe breechl block is operated to open positionas before described, the rear end rides over and cams down `the hammer 52. Inthe 4first part'of-this' movement the block'runs on Ways 90,- which hold. up the' front end ofthe breech block until it has'l f nearly reached the liinit of its'ieciprocating movement. When the hammer iis eainmed dow'nit is caught in 'cocked position by either the shoulder on the hammer or'thefshoulder Gl'of thelhaminerpawl 58 engaging with one'of the two holding shoulders of the trig ger 62, depending-on whether the trigger is in one position or the'other. If the trigger is in the rear position, it will catch andIv secure the hammer in cocked ,position by operatingas shown in Fig. 4. If the trigger is released by the operator, the spring yGli then moves it to its forward position, disengaging it from lthe shoulder-61 and the nose of the 'trigger engaging with the shoulder If thetrigger be n'oW pulled, the lnose eingag'ing with the shoulder-60-Will lbe released,

the lrear 'end ofthe trigger engaging. with 'and elevating to soi'ne extent the rear "end -of thehammer -pawl 58 in effecting the release. `When released the hammer, of course,

T he recoil from 'the sh'ellv will blow back tli'eblock longitudinally, re-setting the hammer, which affords some resistance to the opening i'noye nient, .and bringing alongwith it the inertiav piece 36 and compressing the recoil spring 37,' Which furnishes additional resistanceto vthe opening of the .breech block.v

Before the breech block has reached the limit of Aits rearward increment, theY shell \held by. `the.eXtractoi'voir'Athe one sidev and a engaging with theejector on the other side is expelled through the opening `81 in the side 0f the frame.

This shoulder terminates at the Vupper lend at a point to The-l forward moyeallow the block ltopass it -when'in correct longitudinal position,

The automatic re-load'ing above described takes place so rapidly that theoperatl'or 'is 'l usually unable-to release the trigger intime tovagain secni'e the hammer, and on thisaccount the catch shoulder (Sluis aniinportant factor, in 'that 4it engages with the trigger when in normal tripped position to secure the hammer and provides for returning the trigger' to its normal unti'ipped posi-tion withoutreleasing the hannner.
