l The 'stools is Vapertured and recessed, as shown in 5()y Fig. 2, `to receive the lower part. of the breech mechanism housing frame.- This'frame or receiver 14 is separately illustrated in Fig. 6, and consists of a folded'piece of sheet metal, the upper portion of which iscil cylindrical configuration adapted toi receive a breech bolt, identiied'fgen- `or both of the notches 31 and 32 is' inclined slight-` erally by the numeral 15. J The lower portion of the sheet'metal receiver comprises downwardly extending flanges 16 and 17 which, at their extremities, are spaced and joined by blocks 18 and 19 secured in place by suitable means, rsuch aseo frivets 20. The space between the blocks 18 and "19 forms a channel which receivesa sear 21 and.
the forwardly extending part of a trigger 22.A The forward end of the sheet metal receiver and the e upper surface of the spacer. block 19 are threaded 65 to receive the Ythreaded end of the barrel 10, `as shown in Fig. 2.
The breech bolt 15 preferably comprises ai forward section 23 and a rearward section 24. The Y forward section comprises a tenori 25 oi reduced 70 diameter, while the rearward section comprises an unde11-cut26 adapted to receive the end of said tenori 2 5'.` Integral with the bolt handle 27 `is an apertured member 28 adapted to receive `the tenon25.v The tenon 25 and member 28 comprise 75 Y col-operating key-ways adapted to receive a key 2 9. vIn assembly, the key 29 is inserted in the key-way in tenori 25 and the bolt handle is placed thereon, after. which the rearward' section 24 of the bolt is placedover the end portion of tenon 8O 25 andis 'secured in place by a pin 30.
The receiver comprises two boltlocking vnotches 31 (Fig. 6) and 32` (Fig.'5) The notch 31, which is adapted'- to receive a squared section 33 of the bolt handle, communicates with a longitudinal l slotwhichfis traversed by the ,bolt handle in the forward and rearward movements of the bolt. The notch 32 receives a lug 34 which projects from thebolt handle member'28, as clearly shown in Fig. 5. Ylreierably-tlie forward face of one ly to provide a slight rearward movement of the bolt upon its rotation vby the operating handle,
this movement facilitating the extraction of carte ridge shells from the chamber.
95 The bolt is essentially. a cylindrical shell, open at ,the rear end Vbutclosed at'the forward vend except for asrriall aperture V35 which accommodates the ring pin. The 'forward end of thebolt is chamfered and recessed in the usual manner to receive `the head-of a cartridge, and is'provided with a cartridge extractor 36 andan extractor spring `37V of conventional type, The top of the receiver v14 is apertured, as showninjliigs. 2 and 6, to permit loadingand ejection of shells.
Within the vcylindrical bolt 1.5 is mounted a striker-88 provided at its forward end with a ring `pin 39, and at its rearward 4end with an operating-'handle-ornger piece 40. Said striker f rearward end a substantial portion of its length, the base 4l of said recess serving as an abutment for a iring spring 42 which is housed in said recess and at its forward end abuts the assembly pin 3 0 which extends transversely through both parts of the bolt and throughv slots 52 in the strikerfas clearly shown in Fig. 8. The striker handle comprises an extension 43' of reduced diameter V.adapted to be received within the body vof the striker and secured therein by a transversely extending pin 44 (Figs. 3 and l0) Within the' bore of the striker, and in the rear of assembly pin 30, isv a rebound spring ,45, adapted, when the striker moves forward undenth'e actionof the firing spring 42, to be compressedrbetween the end ofthe striker handle eXtension43-and the assembly pin 3G, and being "so compressed, to` retract the striker a suiiicient amount to withdraw the iiring pin from contact with the head of aY shell in the chamber. Y
' The striker comprises a shoulder 46,- adapted to' engage 'anose 47 of the sear Zlwhen the striker is cocked; and a safety shoulder 48, adapted'to engage the nose-4T of ythe sear when the striker isforward, lthereby positively'preventing the striker being driven forward into contact with the cartridge head by a blow on the strikerhandle `14). To engageV with the striker, the sear nose projects through an aperture 49 (Fig. 4)@in the Vbolt,lsaid aperture comprising a narrow forward extension 491 which is traversed bythe nose 47 as the bolt is reciprocated. As shownin Fig. 4, this extension is out of alignment with the nose 4'? when the b olt is locked, and is brought into aiignment with said nose by the unlocking rotational movement of the bolt-"Asthe 'nose 47 reaches the forward end ofslot 491 it engages the rearward end of an ejector` plunger 492,
which passes throughv the face V'ofthe breechbolt, and is thrust forward byvn'ose 47 to eject;l the shell which has been'withdrawn from thelchamber and Aheld on the face of `the breech bolt byexis vclearly. shown in Fig. 4. The cut, or slot corn-v tractorS. The shoulders 46 yand 48 on' therstrike'r SiS-are formed' by transverse cutsonthis cylin-` drical member, the lateral arrangement of which pri-sing the shoulder`46 terminates at the left in aY Vposition such that when the bolt isv unlocked the slot is yout of alignment with theY scar 'nose 47j hence, when the bolt ismoved forward toward breech closing position the s'earV noseV is not engaged'by the shoulder 46, the bolt v'moving forward past said-nose until the nose comes opposite the slot which" terminates in the locking shoulder 43. As the bolt is rotated'tolocked posi- Y tion, the nose 47 entersv this notch; this position being'indicated in dotted lines in Fig. 4. Thus,
the strikeris not cocked bythe reciplocation of Y the bolt, and the engagement of nose 47 with .shoulder 48 renders the gunrsafe from accidental discharge by a blow upon'the bolthandle. In orderr to cock theggun, it is necessary to man- `Vfuallyf retract the striker by means ofi'tlie bolt handle. As the striker is thus' retracted, the projecting end of pin l44 traverses a slot Y5i) inthe-bolt sleeve, and withthe striker in cocked position said piiiis locatedV substantially at the end of the/bolt sleeve; Simultaneously, the vslot 52 moves over the assembl'ypin 30 coming to the position shown Yin Fig.' 3,1m which pin 3G stands opposite 'a transverse extensionY of said slot and thus permits a limited rotation oi Vthe strikerwithinthe bolt.
l 'In'this condition the gun is ready to fire. Pro-V vision is made, however, for rendering the gun safe against accidental discharge with the striker in' cocked position.r This is accomplished by retracting the striker from the cocked position until the pin 44 clears the end ofthe bolt sleeve, then rotating the striker within the bolt sleeve until thepin 44 comes opposite a shallow recess 541 in the end of thebolt sleeve. The striker is thus locked, and cannot be moved forward until it is retracted slightlyand rotated to bring the pin 44 into alignment with the slot 50. When the striker is in forward or fired position, the pin 30 willl occupy the longitudinally extending [part of the slot 52; thus, preventing relative rotation of thestriker and bolt sleeve. When the striker is cocked, and in firing position, the bolt cannot be rotated to unlock the breech by reason of the engagement of sear knose 47 with theV lateralfedge 53 of the sear nose receiving aperture,uand the engagement of pin 44 on the striker head in slot 50 in the bolt sleeve. If, however, theY striker/ is moved to safev position, the margin V53 of the v aperture is thereby moved away from striker nose 47 an amount suiiicient to a1- low the bolt to be rotated and unlocked. It is thusv impossible to open the breech when the striker is cocked, and in firing position, but the breech may be opened with the striker'infsafe position. Provision is thus made for removing an cutjadapted to receive a portion of said tenen and retain said-handle and key thereon, and
