-To a/ZZ whom zit may concern:

Be it known thatl, EDWARD E. REDFIELD, a citizen vof the United States, residing at Glendale, in the county of Douglas and State of Oregon, have invented a new and useful Magazine-Rifle, of which the following is a speciication. Y e e The present invention relates to magazine rifles, and more particularly to improvements in the construction of the breech mechanism.

It has for one of its objects to simplify the construction and reduce the number of parts, so-as to lessen the cost of manufacture, diminish the liability of mechanism getting out of order, and improve the operation.

A further object is to lprovide a simple andv effective means for detachably connecting the grip piece of the riile with the breech block, `and for locking the latter in position. With these objects in view, and others, as will appear as the nature of the invention is better understood, the same comprises the novel features of construction and arrangement of parts, described hereinafter and set forth with particularity in the claims appended hereto.

In the accompanying drawings, which illustrate one of the embodiments of the invention, Figure 1 is a side elevation of a magazine riie with my invention applied thereto. Fig. 2 is a side elevationdrawn on an enlarged scale of the breech mechanism of the rifle, with a portion broken away to show the locking device forl holding" the breech block in firing position and for attaching the forearm attachment, or grip piecegwto the breech block. sections of the breech mechanism showing the parts in an open and closed position, respeotively. Fig. 5 is a detail view of ,the locking device in a position different from that shown in Fig. 2; Fig. 6 is a perspective view of the-key or locking member of the device. Fig. 7 is alvertical transverse section on line 7,-7, Fig. 2, looking in the direction indicated by the arrows.` Fig. 8 isa perspectivefview of the combined breech block, magazine tube and extractor. 'l

7 designates the hammer and 8 the trigger, which are actuated by springs in the usual manner. j

Y The breech block 9 is preferably made with an integral tubular portion l0 forming a part of the rear end of the magazine tube 10 although, if desired, the tubular portion may be separate from and suitably secured to the breech block. The front wall of the breech block, as shown in Fig. 8, is provided with a vertical groove 11 having opposed overhang-` ing oulders 12, so as to receive the beaded hea of the cartridge, indicated at 13, Figs. 3 and 4, this construction forming the extractor. It will thus be seen that the extractor, breech block and Aa portion of the magazine tube are formed by a single piece, 0r unitary structure.

The breech block is provided with a narrow, upright slot 14 extending from the bottom thereof, Figs. 3, 4 and 8, in which is arranged a lifter l5 that is pivoted at its rear end on the pin 15.. Extending downwardly from the rear end of the lifter is a lug or nose 16 that is adapted to abut the hammer when the breech block reaches the last part of the rearwardv or extracting Inovement, thereby causing the lifter to tilt on its pivot and raise the forward end of the same to eject the fired cartridge and elevate`the succeeding unfired cartridge to the proper position for recharging, as shown in Fig. 3.

The nose is also adapted to engage on its forward movement the ,abutment 17 that preferably takes the form of a screw bolt extending transversely in the frame 1. By abutting the screw, the lifter is caused to be lowered at its front end so that its upper edge will lie even with or slightly below the bore of the magazine or tube portion of the breech block, so as to permitgtlhe next cartridgeto y be advanced by springin the magazine tube, in the usual manner, aslshown in Fig. 4.- p i The ring pin 18 islocated in .the breech lock in a position above the lifter and is suitably connected therewith -so that, as the .lifter is elevated,:the firing pin is retracted in order toA permit the succeeding cartridge 'to be lifted into osition without its comingin 'roc contact Ywith .t e pin. 'For connecting these two members,A the lifter is provided -Withba vIO AFigw, is mounted. inthe recess, the same 4to lock the breech block inthe iiring position, which position is indicated in Fig. 2.

having a partially circular portion 27 which. is loosely set in the partially circular end of.s the groove 25, so as to lpermit of a limited pivotal movement of the detent. This locklng piece is provided with a rearward extension 27 having .a laterally projecting lug 28 that is adapted to engage in the notch 24 of the bar 22, thereby locking the grip piece tothe breech block, as shown'in Fig. 5, dur# ing the extracting and 'loading movements. The frame 1 is grooved longitudinally at 29, Fig. 7, to receive the finger 22- and the detent, and permit of their moving back and forth therein. The locking piece 26 also serves this pur ose, the locking piece or detent is provider? on the upper\edge of the rearward extension 27 with a shoulderSO that is adapted to engage with a stop or abutment 31 formed by cutting away a portion of the up.-

The two walls of the'notch 24 ,are slightly inclined at the rear fromv a vertical line, so that by a suiiicicnt pressure exerted in a forward direction onl the grip piece 21, the lug 28 will" be. forced out `or raised from the notch 24 and upon the bevel 23 of the finger 22. This disengaging of the lug 28 from the notch 24 takes place a proxi-v mately at the end ofthe forward or reibading point that the front en of the grip piece 21 abuts the eye 32 for supporting the magazine tube 10', the lug 28 seats in a slight depression 33 in the bevel 23 of the-finger 22, the ngerhaving a slight degree of resiliency in By this means, the breech block is positively locked in positionso that the reacting Jforce resulting from the firing of Whilethe parts are in the position shown-in Figl, it is a velg simplle matterl to detach om t e' breech block, this accomplishedby first disengaging the l l 5 and then sliding off the grip piece in a forward direction from the' magasucceeding u Vzine `tube. If it is desired to remove the breech block and magazine tube, the hammer 7 is firstl taken out and then the breech block and tube can be withdrawn from the frame I shot has been iired and the parts yare in the position shown in Figs. 1 and 2. YThe grip piece 21 is next movedrearwardly to eject .the ired cartridge and shift the succeeding uniired cartridge to a position for reloading.. At the beginning ofthis rearward movement of the gripl iece 2l, the finger 22 attached thereto'yiel s sli htly ina downward direce tionl so that the dug 28 can disengage from the depression 33 and engage in the notch 24, as the iin er moves rearwardly with the grip piece. T e notch 24 is of suflicient depth to receive'the lug 28 when the detent26 is tilted to its lowermostosition. This tilting ofthe detentl is effecte by the curved front wall of the notch 24, which serves as a cam for engaging around the curved lugl 28, thereby causing the lug to move to the bottom of the notch 2'4. .By this movement of the detent, the shoulder 30 is disengaged from theabutment 31, and the parts assume the position shown in Fig. The grip piece 21 is thus positively connected with'the'breech block so that the latter will be. moved rearwardly therewith. In other words, the arts become positively locked or connecte to effect the extracting movement ofthe breechblock IOC after the grip piece has passed through a limited lost motion, which lost motion 1s necessary tounlock the detent 26 from the frame l of the riiie.. As the` breech block is moved rearwardly, the lifter 15 is hanging in a position corresponding to that shown 4in Fig. 4, land the hammer, which js impinging onV the vrear end of the breech block, is gradually tilted on its pivot to a cocked position. Be-

fore the breech block reaches the end of its rear movement, the hammer rides 0H the rear end of the breech block into the ath of the nose 16 of the lifter, so that whent e said l nose abuts the hammer, the forward' end of the lifter will be raised so as to carry the un lfired cartridge in thenmagazine tube lying above it, upwardly in the-groove 11 tothe position shown in Fig. 3, the said uniired cartlidlge in its upward 'movement ejecting the s e multaneously with the raising ofthe llfter 15, the ring pin 2Q is withdrawn sufficiently, through the agency ofthe slot and -proiection connection between the lifteiand firing pin, to remove the point ofthe i mg pin out of the extractor o'o've 11 so`as to permitthe ed cartridge to be raised to a of the previously -ired cartridge. xii#` the parts thus in the 3, the grip piece 21 is moved forwardly with. 28 to be A thrown out of the notch 24 as the grip piecevl loading position without hindrance.

block, the unred cartridge oi the breech that was raised into position by the lifter onI the preceding rear stroke is moved into the barrel of the gun and the lifter falls to its lowered position. At the end of the forward stroke, the parts occupy the positions shown in Figs. 2 and 4 except that the hammer in Fig. 2 is cocked. The triggervis next pulled, thereby releasing the hammer which strikes the iiring pin and through the same fires the cartridge. By reason of the slight lost motion between the projection 19 on the lifter and groove on the iiring pin, the striking of the latter does not necessarily have any effect on the lifter. This completes the cycle of operation, and for ejecting the iired cartridge and iring the succeeding uniired one, theabove described operations are repeated.

I have described the principle of operation of the invention, together with the apparatus which I now consider to be the best embodiment thereof, but I desire to have it underbreech'frame, a breech stood that the apparatus shown is merely and that such changes and modiillustrative,
