FIREARM.

Original application led June 6, 1916, 'Serial No. 101,931. Divided and this application led September -Y 1s, 1919. serial No. 324,401.

To all whom t may concern:

yBe it known that I, JOHN D. PEDERsENa citizen of the United States, residing in Jackson, in the county of Lincoln and State 5 of Wyoming, have invented certain new and useful Improvements in Firearms, of which the following is a'specification.

This invention relates more especially to that class of magazines which are applicable to breech-loading shoulder-arms, and a principal object is to furnish an improved mechanism having means for effecting and safeguardin the operation of feeding cartridges out of te magazine to the loading-in mechanism of the firearm.

` For convenience of illustration, and to facilitate comparison of certain details, my

present improvements are herein shown employed in connection with other mechanism which is or may be contained in or supported by a frame work such as illustrated in U. S. Patent No. 1,317,988, issued to me October 7th, 1919, lon my application liledxJune 6, 1916', Serial No. 101,931. Thisframe or receiver is of the so-called take-down class and constitutes the subject-matter of U. S. Patent No. 1,429,621, issued to me, to which reference may be had for a more complete explanation thereof.

In the accompanying drawings forming a part of this specification, Fig. 1 is a side view or elevation, of the breech-loading magazine firearm shown in my said Patent No. 1,317,988; in these views,-'which show portions of the stock, barrel and magazine roken away,-the frame or receiverv is shown of the preferred form thereof as' already stated, but only a few of the details of the mechanism are shown or indicated.

40 Fig. 2 is a side view or elevation showing the frame in section, and the breech action fully retracted; the slide and bolt Yare shown partiallyand in side view and in the fully retracted position thereof; also, this view (Fig. 2) illustrates some further mechanism and devices described insaid Patent No. 1,317,988, (see Fig. 8 thereof) and with which, amongothers, my present improve- I ments are adapted for use in a cooperative manner-,as hereinafter more fully explained. Figs. 3 to 8 inclusivefare a series of thirteen. views 'further illustrating the magazine mechanism, and the means comprised in, or -apprtenant to, the same, for detaming and releasing the cartridges; in this series of f views,l Fig. 3 is a cross-sectional view about o n the line X3 of Fig. 2 viewed in the direction of the arrow; Fig. 3 is a fragmentary longitudinal section (corresponding to a por tion of Fig. 2) taken on the line Xga `of Fig.

3, and showing parts at the left-hand'of said line; Fig. 3b is a companion view to Fig. 3a, being taken on said line X3a and showing parts at the right-hand of said line as seen from the left-hand thereof; Figs. 4 and 5 are views similar to Fig. 3, and illustrate different positions of certain of the operative details, which positions are further shown in Figs. 3, 4a, and 5b; and, Fig. 5 is a view similar to Fig. 3b and is supplemental to Fig. 5", for indicating an intermediate stage in the delivery of a cartridge from the magazine tube, 5, onto a cartridge carrier, as 8, such as shown in Fig. 2; said cartridge feeding-out operation being shown completed in Fig.- 2; Figs. 6 and 6a are respectively, a de- -tail side and end elevation of the cartridge m'embers interlocking means preferably.

comprises interengaging tongues and recesses, or ribs and grooves, arranged for rigidly but releasablyv positioning and retaining each said member with relation to the other. In the present instance, as also, but more fully, shown in said separate application, the projections engage in corresponding recesses, and the ribs engage in correspondn grooves or channels res ctively; but tlese features while convenient for use in connection with my present in vention, constitute no part thereof.

The principal members of the firearm mechanism are indicated inthe drawings by the following characters, viz: the barrel, by 1; the receiver, or forward frame-meinber, by 2; ,the guard-frame -or rearward frame-member, by 3; the stock, by 18; Vthe trigger, by 4; the magazine, by 5; the reciprocatable block or base-member, or slide, of the breech action, by 6; the breech-bolt, by 7; the carrier, (which in this instance, is a preferred kind of combined carrier and ejector), by 8; the carrier detent by 19; the extractor,"by 9; the detainer and release member, by 10; the action-bar, by 20; the cartridge-stop or stop member, at the magazine outlet, by 11; the magazine follower, by 12; the magazine spring, by 13. The firing devices, and usual actuating means therefor, are not herein illustrated, but, in practice, these may be such as described in said prior patent 1,317,988.

The firearm frame as herein illustrated may comprise a frame or receiver having an opening in only one of the four sides thereof, so that the right-hand and lefthand side walls, as also the upper side, may be unperforated by any opening which would permit the escape of gases or metal dbris in the event of a back-fire or a premature explosion of a cartridge at any time during the loading operation. For meeting such conditions in the most desirable manner, the frame, or receiver, as 2, is preferably provided with the single ejection opening, as indicated at 2g, and

. which is always in the lower side when the firearm is held in the more usual manner, this being theiarrangement indicated in the drawings.

One form of reciprocatable breech action is deemed to be especially suitable for use in connection with my present improvements, is herein shown, it comprising a slidable base-member, as 6, (which in pracl tice may have any suitable form and proportions), and a rotatable bolt-member, as 7, which operates in combinations that include an extractor and a firing-pin, together with the usual, or suitable, details and features properly appurtenant thereto. The usual action bar, as 20, is coupled to the slide 6 by means of a rib formed on the action bar and engaged into a suitable slot (not shown) in the slide 6. An ordinary hand piece or operating handle,-not shown,-may be fastened to the action bar 20 forwardly of the receiver, in a wellknown manner, for the purpose of operating the breech action; In the presentinstance, the action bar 20 is shown located on the left-hand side of the firearm. For the purpose of simplifying the illustration of my present improvements in the drawings, only one form and arrangement of reciprocatable breech action is, indicated therein.

The particular form or kind herein illustrated, of combined loading, firing and i shell-ejector mechanism enclosed within the frame, comprises as indicated in Figs. 2 and 5a, a carrier, 8, which is operable transverse-ly of the barrel, to and from three positions, viz, one terminal position (Fig. 2) for receiving (on the side thereof toward the barrel) a cartridge from the magazine 5, a second terminal position for receiving (on the side thereof toward the magazine) a shell from the barrel, and a third and inranged for actuating (on a forward stroke thereof to firing position) the said carrier to its second or shell-receiving position, In practice, however, other kinds of carriers may be employed in connection With the magazine devices now to be described.

The magazine mechanism may be said to comprise a suitable tube, as 5, combined with some suitable spring-actuatedl means (such for insta-nce as a follower, as 12) for pressing the cartridges rearwardly, and with some operably-arranged cartridge retaining and releasing means. These means, in my present improvements ,in the preferred form illustrated in the drawings, comprise a pair of separately operable devices one of which is positively actuated by the breech action subsequent to the locking of the breech-bolt in firing-position, while the other is o-perable in one direction by an ordinary spiral spring and in the other direction by the magazine spring 'acting through a follower and a cartridge, and is blocked,during a proper period of time,-by means appurtenant to the breech action. A preferred form and arrangement of such a cartridge stop-device or stop member is specially illustrated in the detail views, Figs. 3 to 5", and for convenience, is designated in a gen'- eral way,-as a whole,-by 11.

Similarly, a preferred form of cartridgedevice or detainer-releaser member (which is not, by itself, a cartridge-stop) is similarly designa-ted in the same Views, by 10. Thus the operation of these magazine devices is normally timed and controlled by the breech action through some parts or -means appurtenant the-reto; also, this control, (and the timing as regards the releasing of a cartridge), is effected at a time when by a complete retraction of the breech action, the swinging carrier, as 8, (when this kind of carrier is used) is in its most inclined position downwardly and forwardly from the pivotal axis thereof at 8, (Fig. 2). However, the said member 10,-this be-- ing a combined device having several funcbreech action is only merece tions, including that of a cartridge-detainer and releaser and action-bar lock, is not acvtuatedl by the breech act-ion at any time,

since the described control vby or from the ermissive in character, so that, on the ull retraction of the slide 6, the notch or recess 20", in the action bar 20, permits ythe releaser 10 to be actuated, by means not appurtenant to the breech action, andpto a position for engagilg forward ofsaid action-bar face at 20", ig. 5), thus directly locking the breech action until a cartridge has been fully de livered out of the magazine, or until the combined releaser and action-bar lock 10 shall have been operated by hand to the position indicated in Figs. 3, 4.

Considering this general operation of the firearm with relation 'to the loading of the cartridges into the barrel, Fig. 2 ma beassumed to indicate the first stage of tliie cycle of moyements. In this view, it will be noted that the rear-most cartridge y2 in the magazine tube 5, (being under the tension of the ma azine spring 13)-, is forced backward against the pivotally-supported cartridge stop 11 as also shown in Fig. 3. ln Figs.

3, da, the head y' of the said cartiidge y2 is stopped from rearward movement in the magazine by striking against the transverse stop-face 11a of the cartridge-stop 11, as indicated in several of the detail views.

- The, said combined member 10, see Fig. 6, is shown constructed in the form of a lever pivoted at 10and having the upwardly extending arm 10g. rlhe curved surtace 10 of said stop 10 extends above the.

cartridge suiiiciently to engage the cartridge head' y and thereby prevents the rear end of the cartridge from rising, when the lever- 'arm 10g is blocked by the action-bar, asin Figs. 3 and 4.' It will he understood, of

' course, that the rear end of the cartridge could rise or be displaced upwardly out of axial alinement with the magazine by the amount of side play that the cartridge would have in the magazine proper. As seen in Fig. 3, the top end 10 `ofthe member 10 bears against the side of the action bar 20, so that the curved surface 10, will prevent the head of the cartridge from moving upward-also, see Figs. 4 and 3. As long as the head ofthe cartridge isQ prevented from moving upward and from riding upward and olf the inclined face 11 on the cartridge stop 11, the cartridge will be prevented from escaping rearwardly out of the magazine. a

in F'g. 2,- it will be noted that the carrier 8 has been moved down to its lowest position, the slide 6 bei at the end of the backward operating stro e, or retraction stroke,

' of the mechanism; in this position the carrier is at the end of its downward or shellejecting stroke which is also its cartridgereceiving position. At this time theaction f bar 20, with its notchQO", has -been moved .backward until said notch is' opposite the ridge rearwardly; the head of the rJear-inostcartridge in moving back being free to ride rearwardly and upwardly upon the inclined stop surface 11s of the, cartridge stop 11, as already explained. The cartridge just fed from the magazine now rests'over, and is supported by, the carrier, or carrier-arms, as shown at y, in Fig. 2. -As this cartridge moves rearward (Fig. 5a), on passing entirely out of the magazine, it allows the front end 11e of the cartridge Stop l1 -to move inward under the inuenc'e of the cartridFge stop spring 11, to the position thereof in i 3.

Thg next cartridge moving rearward under the influence of the magazine spring is thus prevented from leaving the magazine. As this next cartridge moves rearward to'strike the cartridge stop, its head comes against the inclined surface 10e of the detainer-releaser member 10, and thus operates to move the lower end of the detainerreleaser member downward, and outward again to the former position. This rocking or oscillation of this member moves the top 10"' thereof inward, thereby removing the blocking means from the notch 20 in the action bar. lt follows, therefore, that the action bar 20 and slide 6 are now free to be moved forward, for continuing the operation of the firearm mechanism. It will be noted that said slide and the action bar will be locked in the open or rearward position latch from its locking engagement witlrthe action bar. Thus, untila cartridge has-been fed completely and correctly from the magazine, the breech action is blocked lin the open position,

The rearward cartridge in the magazine is normally held inthe magazine by contact with the front end 11 ofthe cartridge stop,

Fig. 3, until the slide 6 lagain reaches its `forward position, as shown in Fig. 4% At this time, an actuator-face at 6, (Fig. 3") on one side of the right front end of the lili@ lll@ Y slide 6 engages the surface Maf-which is shown inclined to the movement of the slide,-and thus moves the forward end of the cartridge stop 11 outward until it is in the position shown in Fig. 4, This allows the rear cartridge in the magazine to move rearwardly from the position in Fig. 3 to the position in Fig. 4a, and thus completes the cycle of movements.

In practice I prefer to employ a manuallyreleasable locking; device for holding the bolt-carrying block or slide 6, in forward position, Aand for this purpose I have herein shown a lever form of such a lock, as more fully set forth in'said prior Patent No. 1,- 317,988. The location of this slide-releaser or unlocking lever, as 22, is such as to be accessible within the rearward part of the frame-opening 2g convenient for manual operation andA at the vsame time protected by the adjacent wall of the receiver or fra-me. This arrangement, as explainedv in said patent, enab es the operator to try the operativeness of the lever 22, even when the breech action is partially or fully retracted, since, in practice, said lever should have some,-a slight,play as between the adjacent parts above and below, so that the oper-1 ator may at any time examine, '(by such a manual inspection as here indicated), whether or not the lever is in a proper operating condition.'v

For more conveniently' inserting? cartridges into the magazine, the breech action should be slightly advanced from its fullyretracted position in Fig. 2, but more than a full cartridge-length of clear spa/ce should exist in the mechanism chamber, between the forward end of the slide 6 and the rearward end pf the magazine tube 5. The cartridges may now be inserted through the bottom opening 2g, and then be readily pushed forward into the magazine; in this operation the spring-actuated detainer releaser-member 10 is, of course, retracted by the pressure. of the cartridge shell itself. These operations are more fully described in my said Patent No. 1,317,988.

A cartridge may be inserted by hand into the barrel in two ways. Assuming that the breech action is completely retracted (Fig. 2) and the magazine empty, one way is for the user to press the lower side of the detainer releaser member, 10, outwardly, which moves the top part 10c of the member 10 inwardly and out of engagement with the notch 20b in the action bar 20, (Fig. 3). This allows the action bar 20 and the breech action to be moved slightly forward as already stated, so that the carrier 8 may be manually moved upward to a pre-ejection position (not herein shown) at the rear' of the barrel chamber. A single cartridge may now be readily introduced into the receiver chamber by hand, and then pushed forneeaeoo wardly into the barrel, either by hand, vor

`by operating the mechanism.

In a complete firearm mechanism, and especially in such a complete mechanism as illustrated in my said Patent No. 1,317,988, the devices appurtenant to the magazine, and which are operable and cooperative for detaining and releasing a cartridge, may be considered as constitutin one .element of combination, and may ge designated a cartridge-detainer, or as cartridge-detaining means, since the specific construction and arrangement of these devices is evidently immaterial to lthe principal functions of the combined loading, tiring and Shellejecting mechanism of the firearm considered as a whole. In'the form thereof here? in illustrated, the cartridge detainer mechanism,-considered as a whole,-is of a composite character and comprises two mechanically separate devices one of which is a stop device, as 11, while the other device as 10, is adetainer V(at certain times) an also areleaser, which, as elsewhere herein more fully explained, operates to shift the cartridge head out of engagement with the said stop device. Thus while a stop device is cooperative with the cartridge and the breechl action, the actual delivery of a cartridge out of .the magazine is not effected by operating any stopdevice, but is accomplished by a bodily movement of a releaser that is by itself neither a completely effective stop nor a complete detainer.

For a further illustration and description of my present invention asemployed and operable in connection with an improved breech-closing and bolt-mechanism, reference is hereby made to the aforesaid Letters Patent No. 1,317,988 granted to me on a copending application, and-dated October 7, 1919; but since my present invention constitutes a distinct and separate subject-matter, it was not specifically claimed in said prior application; and, it should be understood that the improvements herein set forth and claimed are readilyadaptable, wholly or in part, for use with various well-known kinds of reciprocatable breech-mechanisms, different from the preferred kinds illustrated in said Letters Patent and in the present application.
