construction of the latch for `holding the magazinein place. 1

While my invention is not confined to a .firearm of any special type, as it readily adapts itself to theso called class of automatics,V I have selected one of this type for the purpose of illustrating my invention herein, andin the accompanying drawings the numeral 20 denotes the stock of Amy improved firearm, including a fore-end 21,

`which parts may be constructed aof wood -shaped to receive the metallic parts ofthe. gun inv any well known manner, and' which l metallic parts -includea 'receiver 22 havin 'a.barrel 23' secured to Ait in any desire manner.

end, the front end being closed by a wall Thisre'ceiver 'isf-in theA form of a housing, openat the bottom and at the rear 24 havin-g openings through one of which a l magazine tube and carrier operating lever to be hereinafter described extends, and also having recesses 81 and 82 tov receive the f oreend and triggerguard plate.. This receiver or housing has alsdanv ejector opening 25 lin .one sidev wall, .both walls having ears 26 ybetween which the front end ofthe stock is received and to which it is secured. vA

trigger guard plate 27 fits between the side I parts of the receiver at its lower edge, closing the bottom opening thereinto, the front end of this plate being shaped for reception within a lip 28 at theedge of the recess 82, vand the rear end 29 of said plate 27 eX-l tends Yupwardly between the side parts ofthe -receiver to the upper wall thereof closing the back end of the receiver and thus forming a chamber 62 within which the firing mech- -anism fis located. -An opening 30 extends through this `rear end 29 and the trigger guard platehas the usual trigger guard'32 and a rearward extension Y31 terminating in an upwardly extending lug 33.

A hanger 3 4 is secured to the barrel 23 -and WithinV the fore-end 21,. and \a magazine tube 35 projects .through this han er into an opening 36 in the wall 24, this tu e being removabl 'se/cured in place as by means of a screw 3 .in the hanger 34.'

A tubular magazine 38 is removably locatedwithin the tube '35, and is held in place as by means of a pivotally mounted latch 39 receiving thrust of a follower spring 83' and pressed thereby into an opening through the side-wall 'of the magazine tube, therebeing llhe side walls of the receiver are cutv laway in a vertical direction forming recesses 41 within which a cartridge carrier 42 is mounted to slide in a vertical direction, upward movement being imparted `to the carrier by a carrier operating lever 43 pivotally secured in a hanger M attached to the under side of the barrel, the rear end of this lever being pressed upwardly as by a spring 45 located between the front end of the lever and the under side of the magazine tube, which tube also passes'through the hanger 44. The lever 43 is pivotally mounted in a chamber 67 within the fore-end 21, the lever extending from said chamber through an opening 68 into the firing mechanism cham' ber 62. 4The carrier rides loosely upon the' spoon shaped end of the lever 43 that is located in a groove 46 in the under side of the carrier. A rounded formation 48 appears upon the upper surface of the cartridge carrier at its rear end, and within which a cartridge recess 47 is partially formed, said recess extending in the upper surface of the Cartridge carrier between rising side Walls v49, the upper edges of which are adapted to strike against the shouldersformed at theV extreme top of the recesses 41, ledges 50 on opposite sides of the rounded formation 48 being adapted to strike shoulders .51 located' 'near the upper ends of the 'recesses 41 butv below the extreme upper sides thereof. i L

' A breech-bolt 52 is mounted for sliding movement in the upper part 'of the chamber within the receiver, and vin position to pass over the upper edge of the carrier, ribs 5,3 extending lengthwise along opposite sides of the breech-bolt being located in breech-bolt grooves 54 extending alongl the walls of the receiver ,and oppositely arranged therein. The breech-bolt has side parts 55 at its front end extending for a portion ofthe Adistance backwardly, the rear end of the bolt being solid down to the lower edges of these side parts. front end of each of` these side parts is beveled at 56 to correspond with the beveled rear ends 57 of the carrier 42, so that as thev breech-bolt is lforced forward, its beveled edges striking the beveled edges of the car-l rier will force the latter downwardly intov the position shown in Fig. 2 toV receive a cartridge from the magazine 38, which cartridges being forced backwardly bythe follower 40 strike the rear wall 5,8 of the recess 55 on-the breech-bolt and in` position to engage the upper edge of the cartridge shell and force the cartridge to place in the rsite end against a shoulder on the bar.

The

barrel. The breech-bolt will beprovided with an extractor 60 and afiring pin 61 of any desirable construction, said pin, as the breech-bolt is moved backwardly, striking the rear wall of the chamber 62 and acting as an ejector, as illustrated in Fig. 3 of the drawing. A

A hammer 6.3 is pivotallymounted within the chamber 62 and is forced forward by a hammer spring 64 mounted on a hammer actuating bar 65 projecting at one `end through an opening66 in the front wall of the chamber 62 in thevreceiver. The springA 64 rests with one end against the front wall of the chamber 62 and thrusts with its oppsear 69 is pivotally mounted in the chamber 62, its front end being forced by a spring pressed plunger 70 into position to engage notches in the hammer in a well known manner. A sear actuating lever "7 l is pivoted on vthe trigger guard plate27, its pivot 72- being located 1n a slot in the lever that permitsits rearward Inovement caused by the sear lever actuating cam 73 at the front end yof a slot 74 in the trigger guard plate, in which slot the trigger 75 is mounted. A When the trigger is pul ed backwardly the front end of the scar actuating lever is.` raised, the sear actuatingv prong 'thereon engaging the sear and disengaging it from the hammer. Iny this rising'movepivotally ment of the frontend of the'leverits egagement with the cam 73 causes it to move backwardly, disengaging the prong 76 from the sear and permitting the plurfger 70 to quickly move the sear into position to .again l engage a notch in the hammer upon the next rearward movement ofthe latter. This The back ena of the breech-bon isb'eveled forwardly from the top downwardly, this beveled `surface terminating in a projection `90 extending slightly below the bottom of' the breech-bolt, which projection is adapted to engage a projection 91 located on the front edge of the hammer between its ends. The object of this construction is to enable.

the greater part of thev cooking movement of the hammerto be obtained at the 'initial movement of the breech-bolt, atiwhich time the power exerted' on the breech-bolt'is the greatest; l lAfterthe hammer is cocked the projection on the breech-bolt, cooperating with that. on the hammer, having effected its purpose the breech-,bolt is free to move and complete itsA backward movement, at Aa timewhen the power to move it is much reduced, with little, if any, .obstruction to such movement by the hammer.

A breech-bolt actuating lever 78 is piv- Y otally mounted in the chamber 62, preferablyupon the pivot for the sear 69. The end of this lever opposite its pivot rests against therear end of the ybreech-holt and a breech-bolt actuating bar 79 is pivotally Connected with the lever 78 and projects backwardly through an opening in the lug 33, a breech-bolt actuating bar spring 80 pressing with one end against said lug and the other against a shoulder on the bar: The v,lever 78 l1s of angular shape and the bar 79 is so disposed and attached to the levero at' such point that hthe resistance to opening movement of the breech-bolt is on a line passing close to the pivotal point of connection of said bar to the lever but at one side thereof. This causes said force to be applied almost on the dead center so that the resistance t0-opening movement of the breech-bolt is very great at the beginning of such movement, but this resistance isv rapidly decreased after the initial lrearward movement of the breech-bolt takes place. 4

VVhil'e I have shown anddescribedherein a satisfactory. arrangement and' construcg ytion of' mechanism for accomplishing my purposepthis may be Adeparted from to a greater or lesser degree and yet be within.

the spirit and intent of the invention. A breech-bolt retracting lever 84 is pivotally mounted in a recess in the side of the breech-bolt, its outer end or finger piece projecting into the opening 25, as shown in- Fig. 13. The inner end of this lever is adapted to strike the wall of the recessv85 when the lever is swung to its operative position to retract the breech-bolt, and a presses against, theinner end of the lever an spring actuatedplunger 86 tends to hold it in its inoperative or closed position. VBy

l movingthe lever outwardl to the position shown'in dotted lines in ig. 13 its inner end will strike against the wall of, the recess 85 and-the breech-bolt may be-moved backwardly into firing osition, this -for the purpose .ofi starting t e iringv operation should the breech-bolt happen to be in its forward or closed position.

the breech-bolt actuating lever 78 is adjustably mounted in. the trigger plate, preferablythis pin being screw threadedto t a threaded o ening in the plate and its end having a slot yv means of which it may be turned. The'inner end of this pin is located to be engaged by a positioningv prong 88 extending from thev breech-bolt actuating lever 78, as clearly illustrated in dotted lines in Fig. 3 of the drawings. The end ofthe lever 78 in engagement with the breech-bolt isl rounded to engage the beveled-rear surface yor' the bolt, and the formation of the engaging surfaces of the breech-'boltand lever and the lever itself are so disposed as to cause the force of the breech-bolt upon the lever to 'pass close to but at one side of the pivot for the lever, so that the resistance to openi opening movement continues. By means of the positioning pin 87 .the lever may be so located that this line of force may be caused to pass nearerv to or farther from the pivotal ppnt of support of the lever.. v A

The bottomI of the carrier 42 is of such thickness that when the carrier is in its uppermost position, and as 4indicated in Fig. 3, the bottom of the carrier will partially obstruct the opening into the magazine and thus retain the cartridges in place in the magazine, the `bottom of the `carrier thus acting as a cut-off to so retain the can tridges in place. r
