This application is a refile for abandoned application Serial No. 733,121 filed Novem-- ber 23rd, 1912, allowed October-*6, 1915.

This invention relates to improvements in firearms or rifles and. particularly to auto-' matic firearms in which the recoil is utilized for expelling the used shell and for rechargin the arm. 1

e principal obj ect of this,invention is to provide an improved arrangement of rotatable cartridge magazine and devices for the delivery of cartridges from the same to the firing chamber, said devices being operated by the recoil of the gun.

A further object is to provide an improved mechanism operated by the recoil of the gun, for rotating the magazine as each shot is fired in order 'to bring a new storage chamber of the said magazine in correspondence with the gun firing chamber.

A- still further object is to provide an arrangement of a simple construction for efiiciently and automatically delivering cartridges to the firing chamber of a gun from a magazine mounted in the stock of said gun and capable of holding a great quantity of cartridges in a numberof longitudinal storage chambersprovided in the same.

With these and other objects in view, this tions and arrangements of'pa'rts as will be hereinafter fully described and set forth i the appended claims." g Y In the accompanying drawings, Figure 1 isa side View in elevation illustrating the Fig. 2. is.a detail side. view in elevation partly broken-away, illustrating in detail the connection between the magazine and the firing chamber; Fig. 3 is a detail plan view of a portion of the surface of the rotating magazine; Fi 4 is a detail sectional view in elevation illustrating theinteriorof a d5 storage chamber of the magazine Fig. 5 is a detail side view in elevation of my gun partly broken away, illustrating the operating connections between the recoil operated plunger and the magazine revolving mechanism; Fig. 6 is a detail side view in elevation of the firing mechanism; Fig. 7 is a detail side view in elevation of my improved magazine, artly broken away to show the interior; Fig. 8 is a detail sectional view in elevation illustrating the outlet tube, conveying the cartridges from said magazine to the gun barrel; Fig. 9 is a front view in elevation of saidoutlet tube; Fig. 10 is a front view in elevation of the ma zine revolving mechanism; Fig. 11 is a detail side view in elevation of the device for transmitting the motion to the rotating magazine; Fig. 12

.is a rear View in elevation partly broken .and Fig. 17 is a detail view in perspective illustrating the rear part of the breech block.

The utilization of the force of recoil in devices of this kind for expelling the empty cartridges and for recharging the gun, 1s, broadly speaking, oldand has been applied in many different ways. -The force of recoil has also been utilized in connection with rotatable magazines for rotating the 'same as each shot is fired, but arrangements of I this kind have been devised only in connecmagazine capable of holding a considerable number of cartridges for producing va gun' (-f asimple construction capable of firing a great. number of shots in quick succession.

Referring to the drawings in which I illustrate my. arran ement as a plied to a rifle, 20 is the stock of the ri e in which is mounted a hollow magazine chamber 21';

- 22 is the gun barrel, 23 is the firing mechablock is moved backward, as is usual inautomatic recoil operated guns. Said rod 29 can be used for moving the breech block by hand and therefore also for operating the magazine revolving mechanism con nected to it as will be hereinafter described.

At one side of breech block 24 is provided a pin 31 inserted through a slot 32 of a rack 33. Said rack is mounted at one side of the box containing the firing mechanism and is in mesh within a pinion 34, which in its operation is in mesh with another rack 35 which will thus move in an opposite direction to rack 33; therefore when one shot is fired and the breech block is pushed backward by the force of the recoil,rack 35 will be moved forward.

The firing mechanism is provided with a tube'36 loading the cartridges coming from the magazine to the firing chamber. Magazine chamber 21 has a circular section as shown in Fig. 12 and is provided in its upper part with two plates 37 between which is guided ejector 38; said ejector is provided with a number of. equi-distant prongs or teeth 39 the distance between two successive prongs being efficient to accommodate the length of a cartridge. The same is also provided with a projection 40 on which is inserted a tube 42 connected at the opposite end to a part 43 provided with a cam-slot 44.

Said magazine chamber is provided at its forward end with a wall 45, provided with an opening 46 at the upper part of a diameter sufficient for the passage of the outlet tube for the cartridges. At the rear end of said magazine chamber is provided a bottom 47, and within said magazine chamber is revolu-bly mounted a .magazine drum 48, fixed on a shaft 49. Said shaft 49 projects through and out of the wall 45, and

on its'outer projection is fixed a Wheel 50,

having a ratchet 51 and a cam-portion 52 provided with a number of cam-slots 53, circumferentially arranged on the outer face of said part 50.

Said magazine drum is formed with a number of longitudinal cartridge storage chambers 54, .arranged. along its periphery;

said chambers being of a diameterv sufiicient to accommodate the cartridges used and communicating with the outside face of the drum by means of longitudinal slots 55. The upper storage chamber 54 is normally registering with opening 46 in wall 45 and through its related slot 55, ejector 38 is inserted and operating.

The length of the magazine is such that each storage chamber can accommodate a number of cartridges end to end, as illustrated in Figs. 3 and 4; each storage chamber is provided with a number of springs 56,

allowing the motion of the cartridges for-.

ward but preventing their -motion in the op osite direction.-

ommunication betweentube 36-and the upper storage chamber is established by means of an outlet tube'j57, inserted through the front end 58 of the magazine chamber: and through opening 46, said outlet tube extends into the rear end of tube 36, which is connected to part 58 by means of dowel pins 59, 60 or in anyother convenient man-. ner. Said outlet tube 57 is also provided, as shown, with a spring 61, permitting the motion of the cartridges forward, 'but preventing free motion in the oppositedi'rection.

' Rod 41 is connected to tube 42 by means of a tension spring 62, located within said tube;

zine 48 is rotated one step, said movement,

being controlled by a lever 64, pivoted in 65 to a connection 66,; said lever is provided with a pin 67, adapted to project Within cam-slots 53 and to operate against the sides of the same. Spring 69 will cause lever 64 to swing outwardly, that is to the right looking at the drawing, Fig. 10, when pin 67 is disengaged from cam-slots 53. This disengagement of pin 67 takes place when connection 66 is moved toward shaft 49. Upon said inward radial motion of connection 66 taking place, pin 67 comes out of the cam slot 53 into which the same was previously projecting, spring 69 will cause lever 64 to swing outwardly, and pin 67 will then be ready to engage the next cam slot 53 to right. The downward motion of connection 66 takes place when part 43 is moved forward, and when said part 43 returns to its normal position through the action of the spring within part 30 which controls the motion of rack 35, connection 66 will be moved outwardly ,and will cause magazine 48 to rotate one step, as will be hereinafter explained.

By observing the shape of cam-slots 53, it can be seen that while the right side of the same is in a radial direction, the left side is inclined in such a manner that a pressure exerted against its surface by a part moving in a radial direction will rot-ate the cylinder toward the left. Connection 66 is provided with a vertical elongated slot 70, accommodating shaft 49 and permitting the up and down motion of said connection 66. The upper part 71 o-fsaid connection projects above front part 58 and is bent to one side to clear outlet tube 57; said upper part 70 is provided with a pin 72 projecting through slot 44 of part 43, and which in the position I downward will cause the downward motion of connection 66, freeing projection 67 from the cam slot 53 to which the same was engaged. As soon as said cam slot 53 has been entirely cleared by pin 67, spring 69 will swing lever 64 outward and therefore pin 67 will be ready to engage the next cam slot 53.

The upward motion of lever 64 is limited by a roller 64, abutting against'its side, which will cause the same to assume its normal position when connection 66 will again move outward.

As soon as the empty shell of the cartridge which has been fired has moved back sufiiciently to clear the firing chamber and to be expelled at one side in any convenient manner, a new cartridge can be inserted in said firing chamber from the forward end of tube 36. To insure the unloading and reloading of the gun in a proper manner, the difi'erent parts constituting the firing mechanism are formed and related in a special way. The

'forward end of tube 36 is cut in an inclined direction in relation to its axis, so as to remain parallel to the motion. of the breech block and abutting against the same. At the upper part-of said tube 36 is provided a catch 73 pivoted in 74, and a spring 74 tends to hold the same away from inside of tube 36.

When hammer 26 is in its forward position, however, it will force said catch 73 down; thebackward motion of breech block 24 forcing back hammer.26, will temporarily .ated by spring 77, tending to move the same forward in a longitudinal direction. Said plunger 76 is provided with a spring 78, projecting in the inside of tube 36and' allowing the forward motion of the cartridges but preventing their return motion,,the action of said spring 78' being substantially similar to that of springs 56, illustrated in Fig. 4. j

When hammer 26 is in its cocked position, as shown in Fig. 2, plunger 76 is forced backward against the action of spring 77..

The operation of the device can now be easily understood as follows:

When breech block 24 is operated backward by the action of the recoil, the same pushes backward hammer 26; as soon as the empty shell has been ejected, catch 73 is allowed to move outward, thus permitting the motion of the cartridges within tube 36; plunger 76 which is still free to move, hammer 26 still being on its way to its cocked position, actuated by spring 77 will then push the two cartridges which are in front of spring 7 8, forward, the first cartridge entering the firing chamber. As soon as the rear part of said first cartridge has cleared catch 73, and as the backward motion of breech block 24 progresses, said catch 73, is again forced down thus preventing the motion of'the remaining cartridges beyond its projecting end. In the meantime, rack 35 has been moved forward, pulling forward part 43 against the action of spring 62; as soon as the first cartridge in tube 36 is allowed to enter the firing chamber, said spring 62 will pull rod 41 and therefore ejector 38 forward, thus causing all the cartridges engaged by projections 39 to progress one step forward.

The forward motion of part 43 has caused the downward motion of connection 66 so as to clear and loosen the cam slot 53 previously engaged by pin 67. Slot 44 has a horizontal free said catch, permitting the same to move clear of the inside of tube 36, said breech block being grooved at 73' to allow the outward motion of said catch; after a certain portion of the backward stroke of said breech however, when groove B ends said catch will again be forced down through the action of the inclined surface 73" at the end of groove 73. When said catch is forced down it will abut against the cylindrical portion of the cartridge underneath, and will prevent the forward motion of the same, be cause the rear part of the shell having an enlarged diameter, it will not be possible for this to go past said catch. At one side of tu e 36 is also provided a plunger 76, actuportion 79 and ejector 38 has four projections 80, two on each side. The sides or guides 37 between which said ejector 38 has moved, are each provided with two projec-- ting surfaces 81.

When the breech block has ended its backward stroke thereby cocking hammer 26, the spring wlthin part 30 which has been compressed by the same will begin to act, returning breech block 24 to its former position ready for firing. Through rack 33 and pinion 34, rack 35v is therefore moved backward, causing the backward motion of part 43 and of the ejector 38 connected to the same. The rear edge of projections 39 is inclined so that the same' abut-ting against the cartridges in the storage chamber, which are prevented from getting back by springs 56. will lift ejector 38 until thebackward motion of part 43 continuing, projections 80 will rest on projections 81, and the back- 30 4 emptied of all cartridges; it is obvious that the rotatory motion ofahe magazine can be obtained in many ways through the. appli-- ward motion of ejector 38 will be made in a-raised position in which projections 39 are entirely clear of rotating magazine '48, and

therefore allow the rotation of the same, When ejector 38 is stillinits raised position, the'inclined part of slot 44 begins to acton pin 72,1ifting connection 66 andthere- 1 fore lever 64, connected to the same; the'action of pin 67 against the left side of the new cam slot 53 now engaged, will cause the rotation of magazine 48. When this movement has started, projections 80 can clear projections 81, projections 39 resting on the surface ofthe magazine. As the backward I motion of part 43 continues, slot 44 continues to lift connection- 66 until the one stepmotion of the magazineis complete andejector 38 is free to fall through the slot 55 of the new storage chamber registering with outlet tube 57. The'gun is now againready for firing, and as the new shot is'fired, the cycle of operations just described is repeated.

It is thus seen that as each shot is fired,

all the cartridges contained in the "storage chamber, are' moved one. step forward, the first cartridge in tube" 36., being pushed into I the firing chamber; the magazine is then rotated and the cartridges in the next storage chamber will then be moved one step forward and so on until the magazinehasbeen cation of different mechanical means within the reach of an ordinary mechanic; the device shown and described being intended v mostly for a certain example.-

'To load the magazine, the rear part of the same 47, is provided with an opening with wh ch all the storage chambers register in succession as the magazine is rotated, said openmg is closed by a plug 82 attached to a lever 83, plvoted in 84 to the rear part 47,

and this moved away from the openmg for loading the magazine. When one storage chamber has been loaded through said opening, the step motion ofthe magazine can be caused by hand by pushing. rod 29 and. therefore breech block, 24 backward, thus causlng the entire cycle of movement to take place;

The sprocket portion 51 of part 50 is engaged by a'pawl s5 'p-iyoted in' 86150 wall into the'slot 55 of the storagechamber 'un-. 'derneath, a spring 87 is provided pre'ssing From the foregoing itcan be seen that 45 and preventing the return motion of said part 50' and ,thereforeof the rotating maga- -'-'zme. v I I Y Tofacilitate the dropping of ejector 38 down rod 41.

'- I provide a device simple. in construction and positive in its operation easily assembled and taken. apart; one of the advantages of .my nnproved rotating magazine Is that all thespa'ce available is used for the cartridges,- no space being given to springs or to other devices for controlling the motion of the' same. It is obvious that the form and construction of the difl'erentparts need not be exactly as shown in the drawings, provided their relative functions remain the same; and while it is seen in the drawings'that e ector 38 operates through the outside wall of the rotating magazine, it is clear that the mere changing of said ejector to some other position, would not constitute a departure from the spirit of my invention. I r

Various other changes can be made in the specific details of construction of my machine without departing from my fundamentalidea and I reserve to myself the right to bring to the same all those changes and ber, a recoil operated member, an element controlledby said recoil operated member,

- and an elastic connection between said element and said'feedin'g member. 9
