Mounted'on the sameside or face Vof the block 2 is a member 31, which as shown, is a lever pivoted for movement about the same axis llas the held in its upright position against'an Vabut-V ment 82formed on the block 2.7by suitable means, such as a spring 33, permitting'theV movement of the Vmember 31 away from the abutment` 32V upon the applicationl of suitable pressure. Mountedffor,sliding movement longitudinally of the frame of the gunH of the inventionshown is thrownf'backward'.v Y' This movement of the slide may lie-effectedY in various ways.

1n vthe form of 'the invention shown (see Fig. 1): a by .-p'ass is provided in the forward end of the. gun barrel, this bypass having` a 'portionfin which a piston 37 lits for movementV in a direction longitudinally of thefdirection of movementof the slideV 33. The piston is suit! ably connected to the slide, and'means such as a spring 38 tends tomove the'rpistonto its forward position, the spring engaging betweenV one face of the piston-and a suitableV abutment '2 not showin. Y y l Just before the bullet; leaves the forward end of theV gun, a volume of gras. underpinssure is inclosed in thegun barrelgthis was ton lagainst the springBS so as to shift the slide. The slide with the cam thereonV are shown clearly in 7. TheA cam,t'lbeY ing engaged'betwcen Vthe projection 30 and the member 31Y will now cause the block 2 to move `Vto certain positions` as'h'ereinafter described. Before the bloclr is free to move downwardly, however, the pointed end of the hammer must be removed from the percussion lcapV of Vthe shell. VTo ,accomplish this I have provided lever je()Y pivoted intermediate its ends to the frame of the rifle,A

as shown in Fig. 1. Therear armv ofthe lever 10 lies under the forward arm'of the hammer and theforward arm of the lever 40 lies aga-inst the camt. VVhenthe slide is moved rearwardly, the block will remain for ashort time without movement because the cam has its initial portion which then Ycoacts with Vthe projection; 30 Jand..niemberV .81, parallel to theaxis of the movement thereof. v DuringV this time the proj ectionv 30 travels from point a tov point-b luplonthe cam (see Fig. 7).

forward arm of the lever 40 has been moved downwardly by the incline o of the cam,

The member 11 isnormally At thela'tter instant the' 'draw the pointed end ofthe hammer from the percussion cap. Duringthe movement vof the carn'frorna to b, t-hecam vserves not fonly to permit the withdrawal of the firing- ;pin Von the hammer before the block 2 is permitted tofall,"but also sei'vesto prevent the blockv from being forced downwardly :abougt'the pivotal axis 3 thereof, which, as show-unis located-belowthe gun barrel, by the rearward pressure of the gases and shell in the'lgun barrel upon 'the discharge of the cartridge. Y.

Thebloclr 2 will be'moved downwardly Ywhen the portion of the cam from 7) to l passes between. 'the projection '30 and the movement between "o and d with yrespect to the ,projection 30 vand AmemberV 31,' the empty shell isjthrown partly out of the 4vrille by the 'ejector 12 because between a certain part, foi-example, between e' and 'the ,point Linthe travel ofthe cani .with yrespect to the projection 30,1the block at it'ssui'face 2 engages the rear arm ofthe extractor (see vl*`r`ig.2) toA move the latter-in acloclwise direction referring'tofvligst` 1 and 2. :l/Vhen the projection 30 occupies the position "e with respect to thercam, the block- 2 is in Vsuch a position that the portion of the upper surface of thebloclr to `the rear ofthe lip 48 is' opposite thelowest pointfofthe-rim of the cartridge.' Inasinuch as the. axis of AtheY block lies below the barrel the block in falling not only moves downwardly, but also movesbaclrwardly and gives'a space between the block and the barrel permitting a free movement offthe extractor. When the; projection 30 occupies afposition beyond thepointrd with respect to the cam,

member 31.l Durin(r the latter part of the further movement ofthe cam permits the block to remainV stationary, this being;r for the purpose of insuring the 'complete' discharge of the empty shell from the gun barrel. As the projection 30 by the movement Iofthe slide changes its position from f to g with respect to the cam, the block' 2 isagainrraised to a certain extent, being at the same elevation whenithe projection istat thepoint g' as when said projection is at the pointe. During` this interval the upper surface of the member 31 will not engage the under surface of the cam. Upon the point-e Vand. any point between g and jh upon the cam becoming coincident withthe projection 30 in the movement heretofore described, the block 2 reaches a position 'in Ywhich it rests upon the forward arm of a lever .45 which is normally held up in an elevated position in enga-gement with .the projection 46 by suitable yielding vmeans suchas a spring` 4:7, thisspring being,r come to the point Z with ,respect to the projecf vpressed when the cam moves from `the point the lip 48 upon the forward upper end of theblock 2. During the movement of the cam from the pointe to the point d with respect to the projection 30, the movement of thef;extractor takes place, the further movement of the cam from-the pointl @Z'to the point f securing the complete removal of the empty shell out of the barrel. When the cam reaches the point g with respectto the projection 30, the ejected shell lies on the block 2 and 'thereupon the block remains in the same position during the movement of the-cam `from the point g to the point kvwith respect to the projection 30. During thef earlier part vof this movement'the old shell is pushed off the block and a new cartridge pushed onto the `same by means to be .hereinafterffmore fully described. During the-movement of the camV the latter part ofthe distance between 'g and` It with respect t'o the projection-.30, vthe new .cartridge is -pushed forwardly along the block into the barrel, during' which time the block must remain in a fixed position. The. block as heretofore stated is provided 'adjacent its forward end with af lip or shoulder 481 which v would normallyprevent the flange uponA the cartridge being moved past the same into the barrel. To make possible the movement of-.the lip away from the position in which it prevents the movement of the cartridge completely into fthe barrel, the cam is providedwith a depression .i permitting` downward movementof the projection 30 and of V'thebloclr 2 against the `pressure ofthe spring acting upon the lever 45.r

YV hen lthe cartridge hasbeen moved completely into the barrel the block 2- is then moved upwardly automatically by the last named spring7 the .lip or shoulder 48 partially covering -theadjacent end of thegun barrel so as to prevent the `cartridgeffrom being thrown back out of the barrel. It is to be -understood thatif the cartridge moved partly out of the barrel before the. block 2 waslraised to closingposition, it might prevent the `closing of the barrel bythe block. The new cartridge is now 'in the barrel, .the oldshell is ejected and the slide is thereupon automatically moved forward again to itsV original position by suitable means such as the spr1ng38 heretofore described, there bemgno gas pressure 1n the gun barrel which prevents the spring 38 from returning the lslide to its normal' position.

reason ofthe fact that the member 31 ispivoted at 11,;it yields against the action of the spring's33 (see Fig. 4) whenever it strikes anuobstruction, such as the part lof the camvunderthe point ff ,upon the move-I ment of the` Slide in a forwaidrlircction.

Accordingly as the cam returns lfrom the y point g tothe point e with respect to the projection 30, the member 3l 'after beingturned by the lower portion ofthe cam'lunder. the

33 out of its normal position, the lever'45 v supporting the block in the position with respectto the barrel shown in Fig. .2. It will accordingly be seen that onthe return stroke of the slide the block V2 is never supported vsufliciently low to permitthe car'A tridge to leave the barrel, the lip or projecl tion 48 forming an obstruction until the shown in Fig. 1." A, Briefly stated the movementspof the lock ascaused 'bylug 30, memberl 3l, and lever .45 j are as follows: Upon the initial movement of the slide 33 after firing the blockis held in closed *position by -th'e lug 30 sufficiently long to permit the withdrawal of the iringpin from the base of the cartridge. The block is then pressed downward, the under surface of the cam engaging member'3l.;. During the movement ofthe slide in its initial direc.- i tion (rearward as shown) the member 3l is l Y downward movementv of the block moving the obstruction 48 completely out of the way so as to 'permit' the shell to be freely eX- tracted. The block is held in its lowermost position by :the coaction of the member 31v with-the lower surface of the cam a predeterminedlength of time to permit theshell to be completely extracted.- Thereafter-the blockis raised by the coaction of the lug 30 with the upper surfaceof'the cam, thelip 48 now 'formingan obstruction( to the real' end of the barrel. At the proper momentv this obstruction is removed by the cartridgel asit is moved into the barrel, the rim ofthe cartridge ,pressing the' block downwardly against the action of lever 45 and spring 475 the vnecessary downward movement yof the lug 3()r being permitted bythe compression inthe cam. As soon as the rim of the cartridge has passed the lip 48 theblock automatically. rises tothe positionshownin Fig. 2 thereby. preventing the. cartridge from y leaving the barrel. pon'thev return 'movement of the slide the block never moves belowvthe.position shown in Figg2,l lbeing 7o point f in an anti-clockwise direction will be held down against th'eaction of the spring so block is again movable. to closed vposition as supported vin this lposition either by the coaction of the lug 30 with the upperV surface'of the cam or vby the lever 45 until the cam ooacting` with the lug-3 0 moves the block to closed position shown Yin '.Fig. 1. During this return movement the member. 31 is moved by the cam into inoperative position as described above when it strikes an obstruction and accordingly doesnot effect the movements of the block.

Referring to Figs. 3, 5, and 6, I have shown means for automatically' moving the `cartridge into operative position inthe gun barrel. These means, as shown, comprise a forked member GOwhich is arranged to engage the oppositeV sidesjof a cartridge A and to move the same laterally out of the laterally-` to Aoperative position thefslide 33 may be arranged to engage anV arm 63 which may be secnredto a member-64 mounted for movement longitudinally but` not rotative'ly with respectA tothe hub 65 of the fork 60; Means such as'a spring 66 may be employed to move-the fork back to Vnormalposition.

As shown in'Fig. 3 the fork is `providedat its lower left hand edge withv a projection or flange which prevents the `cartridges from being moved upwardly by the spring 62 as long as the fork is to one side of the normal position'` as shown in the said figure.V The member 64 is rigidly secured to a nut which upon its upward movement or its downward movement is adapted to rotate in one direction or another shaft() rotatably mounted within the part 65. The part has secured upon the upper end thereof a cranlr70 which is pivotally connected as by means of the connecting rod 72v with the pusher -73 mounted within the forkA and adapted upon a forward movement to engage-the rear end of the cartridge and to push the 'same into the gun" barrel.V It is understood that the cam 74'whichr moves the nut 69 is connected to slide 331to'push'the cartridge into the .barrel at the proper moment. The mechanism'for moving the cartridge into the gunzbarrel is mounted in' a suitable position upon the rear of the frame but .has not been shown in VFigsfl and 2, it being thought that the relation of this mechanism for feeding the cartridges with respect to other mechanism will be clear in view ofthe foregoing description and the disclosureof the accompanying drawings.

lhile I have shown the preferred embodiment of my invention, numerous changes to support said block in position tojform an obstruction to said end of the barrel 'without closing the same, and means controlling the movement of said block relatively `to said barrel adapted to cause the` block to be moved against the action' of. said first named Vto support said block inposltion to form an obstructionto said end of the barrel without [closing the saine,AY and means controlling the movement off said' block relatively'toisaid barrel,said controlling means and block being arranged for 'relativezmovement in opposite directions, andV said lcontrolling means causing-the movement ofsaid block against the action of said lirst named-meansaway from said end of thev barrel sufficient by'far to permit the free extraction of ashell duringfsaid relative movement in one direction, Ybut being inoperative to cause such movement of theblock during said relative-movement'inthe oppositedirection.
