The present invention relates to improvements in firearms and relates more particularly to im provements in extractor-and ejector assemblies which include a movable breech-bolt.
One of theobjects of the present invention is to provide a superior extractor, ejector and breech-bolt assembly wherein the said ejector will serve to prevent the unintentional detachment of the said extractor from the said breechbolt.
A further object of the present invention is; to provide a superior construction and arrangement of parts whereby a cartridge-extractor and a cartridge-ejector will each serve to retain the other in place in a movable breech-bolt or' its equivalent.
With the above and other objects in View, as will appear to those skilled in the art from the present disclosure, this invention includes all features in the said disclosure which are novel over the prior art.
In the accompanying drawings, in which certain modes of carrying out the present invention are shown for illustrative purposes:

Fig. 10 is a perspective view of the cartridgeextractor, detached; and
Fig. 11. is a similar view of the cartridgeejector.
Forpurposes of illustrating one embodiment of the present invention, there is" shown in the accompanying drawings, a breech-bolt generally designated by the reference character l5 which is. generally speaking, of cylindrical form save for alightening-cut 16 in its upper face and two radially-projecting locking lugs l1 and I8 integrally formed at its forward end. The two said locking-lugs l1 and I8 extend radially out wardly from the breech-bolt l5 at substantially diametrically-opposite points thereon and are adapted to move into and out of suitable locking-recesses in a firearm in a manner well known in the art and illustrated, for instance, in the well-known Gara-nd military rifle.
In itsforward face; the breech-bolt is formed with a recess l9 which is adapted to successively receive the head-ends of cartridge-casings such, for instance, as the cartridge-casing 2t illustrated in Figs; 5 and. 8. Extending axially through the breech-bolt- IE is a passage 2| in which isadapted to reciprocate a suitable firingpin (not shown) in a manner well understood in the art.-
Eccentrically of and parallel withthe axial passage 2| in the breech bolt I5, the said breech= bolt is formed with a forwardly-opening pocket or ejector-receiving passage 22- in which reciprocates a rod-like cartridge-ejector 23'. The forward end of the cartridge-ejector 23 is positioned so asto extend forwardly into the recess IS! in the front face of the breech-bolt l 5, for purposes or engaging with a cartridge-casing such as 20 and ejecting the same, all in amanner as will more fully hereinafter appear. The said cartridge-ejector 23 is yield-ingly urged forwardly by a helical ejector-spring interposed between the rear end ofthe cartridge=ejector and the bottom of the cylind-rically-contouredpocket 22 in which the said cartridge-ejector reciprocates'.
On its inner face the otherwise cylindricallycontouredcartridge-ejector 23 is formed with a clearance-notch 25, the sloping rear wall of which constitutes a stop-abutment 2B acting in a manner as will hereinafter appear to limit the forward movement of thecartridge ejector 23 under the urge of the ejector-spring 24. The under face of'the portion of the cartridge-ejector 23 lying immediately forwardly of the forward end of its notch 25 acts on occasion as a stopabutment 21 to' limit the movementof a car tridge-extractor, in a manner as will hereinafter appean Laterally intersecting both the axial passage 2| and the ejector-receiving passage 22 the breech-bolt I5 and extending substantially perpendicularly with respect thereto, is a cylindrically-contoured vertical passage 28 which receives the vertical cylindrically-contoured stem 29 of a cartridge-extractor generally designated by the reference character 30.
In addition to its stem 29, the cartridge-extractor 30 includesa' casing 20 immediately forwardly of its i-rear face;
The body-portion 3| of the cartridge-extractor 30 is accommodated in a recess 34 in the upper portion of the breech-bolt l and extends part way into the locking-lug l8 thereof; 'Ihe'fvertif-i cal cylindrically-contoured passage 28 for the accommodation of the stem 29 leads downwardly from the bottom of the said recess 34 and through. the under face of the breech-bolt l5.
tridge-extractor 30 to turn in a direction to'urge its cartridge-extracting lip 32 into the cannelure of a cartridge-casing, an extractor-plunger 35 is employed; The said extractor-plunger recip rocates in the forward end of a pocket 36 formed in the outwardly-and -forwardly sloping rearwall of the recess 34 in the breechbolt i5. Inter-j posed between the inner end of theextractor; plunger 35 and the bottom of the pocket 36 is a helical extractor-spring 31 .urging'theQsaid err-1 tractor-plunger into engagement with a shallow conical recess 38 in the adiacent'face' of the-body portion 3| of thecar'tridg'e-extractor 30'.
Under the conditions above deslcribed, the stern 29'of"the cartridge-extractor 30 will act as stopmeans to limit the forward movement of the V cartridge-ejector 23, but the said cartridge- 7 ejector. will not under these conditions act as a I stop to limit the axial movementof the stem 29.
,When in the operation of the firearm the head- 'end. offfia cartridgeecasing such as is seated V A hgt f iecess lfi'l in the forward end of the breech- For the purpose of. yieldingly urging the car- In its inner face adjacent-it's lowei' stem 29 of thecartridge-extractor'30 isformed with a clearance-notch 39 facing slightly forawardly but mainly toward thecartridge-ejector 23. The curved lower wall of the said clearancenotch 39 constitutes a stop-abutment 49' adapted to engage withthe stop-abutment 21 of'th'e car; tridge-ejector 23, in a manner as will hereinafter appear. The'portion'of thefstem 29 which is located immediately to the rear of'the clearance-j notch 39 constitutes a rearwardlyfaci'ng stop-1 abutment 4| which is adapted tojbe engaged by the forwardly facing stop-abutment 26 ofthe cartridge-ejector 23.
In assembling the parts-above described, the extractor-spring 31- a'nd'the extractor-plunger may be installed-in the pocket'36 in the breechbolt,-and the cartridge-ejector 23 and the ejectorspring 24 -may be installed in the longitudinal pocket 22. Now by manually forcing the car tridge-ejector '23 intoa position very slightly rearwardly of-the positionin which it isshown in Fig. 6,'the'clearance-notch 25-thereinj will-be brought into full unobs'tructing registry with' thej vertical passa'ge 28. Under these conditions, the cartridge-extractor -30 :may be installed in the breech-bolt by" a'downward movement causing its stem'29 to pass downwardly; through the vertical passage 28'and through thenow-registering' clearance-notch 25' in the cartridge-ejector until the said cartridge-extractor is fully in place Infmoving downwardly,"th body port'ion 31*"01 '7 the cartridge-extractor will cam the' extractor plunger 35 rearwar'dly and outwa d lyunt'il the conicalrecess 38 "in F the cartridg'e-'-'(=,ii tractor is brought into registry with' the sa'i'd extractor plunger, whereupon the-said extr ctor-plun er will snap into thesaid recess "38. The full registry of the recess' j-38 and the extractor-plunger 35 will occur when'the cartridge-extractor has been .fully seated" inthe breech-bolt and when the clearance-notch 39 in' the stem 29isinhoriz onta1 registry. with the cartridge-ejector 23. r As soon asthecartridge-ejector 23 is released from. rearward manual-restraint, the ejectorbolt and is engaged by the cartridge-extracting lip 32 the cartridge-ejector will be held'in its rear'position as shown in Figs. 5, 8 and 9. In
this position, the stop-abutment 21 adjacent the forward end of the clearance-notch 25 inithe cartridge-ejector'23will-be entered into the clearance-notch '39 in' the stem29 of the cartridge;
