CARTRIDGE-MAGAZINE.

' Application filed May 15,

gate type adapted to hold cartridges trans-' versely therein, either in a single column or in a double column with the cartridges of the two columns disposed in staggered relationship with each other, and adapted to be detachably secured to firearms in position to feed the cartridges thereto. 4

The principal objects of the invention are to provide a magazine which is simple and reliable in construction, which is light in weight so that it does not appreciably add to. the weight of a firearm when attached thereto, which is inexpensive to produce even to the extent that it maybe discarded when emptied, which may be formed entirely of sheet metal, which has a guide pressed therein for detachably connecting it to a firearm, which may be assembled and disassembled without tools, which has a follower adapted to lift the rear-most cartridge of each column of two staggered columns of cartridges, andwhich has means for controlling the action of an automatic gun when the magazine becomes empty.

In one aspect the invention comprises a cartridge case, preferably a sheet metal case of tubular form, having a wall bent to form a guide adapted to fit into a corresponding ide in a firearm, said Wall preferably bemg pressed outwardly to form .-a hollow guide having a T-shaped cross-section, whereby the case may be detachably fitted to a firearm. More specifically the invention comprises a tubular case having a longitudinal slot in one side thereof and having a hollow guide disposed longitudinally along said side, said guide havlng a T-shaped cross-section and having its edges integrally connected to the edges of said slot the base of saidT-shaped guide being. relatively wide so as to have overhanging portions adapted to fit into the recesses of a recessed channel in a firearm or other device to which it is desired to attach the magazine.

In another aspect the invention consists in Specification of Letters Patent. Patented Aug. 24, 1920- 1919. Serial No. 297,286.

.a magazine having a delivery opening through which cartridges may be delivered to a firearm or the like, and means including a follower for impelling cartridges toward said opening, together with means associated with the follower for stopping or otherwise controlling the action of the firearm; When'the magazine comprises a tubu- I empty. In order to receive the said part of r the control mechanism of the firearm a portion of said guide is cut away andprefer-v ably thev upper 'end' of the guide is cut away so that the guide terminates at a distance from the delivery end of the magazine suflicient to permit said means associated with the follower to project beyond the end of the guide when the magazine becomes empty.

In another aspect the invention comprises a closure for the rearward end of the tubular cartridge case having at least one portion extending along the wall of the case and thence into a slot or other openingin the wall of the case and preferably two such portions on opposite sides thereof adapted to extend into slots in the opposite sides of'the tubular case. The closure is preferably formed of sheet metal and when so formed said portions are preferably in the form of integral tabs or fingers bent at right angles to the closure and adapted to extend along the inside of the walls of the case and to hook into saidslots, said tabs or fingers being sufliciently flexible to be unhooked from opposite sides of said transverse portions along opposite walls of the case to hold the follower in proper position. The follower is preferably formed of sheet metal and when so formed said longitudinal portions are preferably in the form of right-angle flanges adapted to slide along opposite walls of the case. A portion of one of these flanges may be struck up to form the aforesaid control means adapted 1 .In order more clearly to set forth the na-.

to extend into said hollow guide. When the magazine is made of such width as to hold cartridges in two columns with the cartridges of the two columns disposed in staggered? relationship to each other, the follower is shaped to engage the rearmost cartridge of each column by providing a raised portion on one side thereof. .When the follower is formed of sheet metal said raised portion is preferably formed by bending one side of'the follower upwardly as hereinafter described.

The particular embodiment of the invention shown for the purpose of illustration comprises an elongate tubular case C having a cross-sectional contour which in general is rectangular as shown in Fig. 6. The forward wall of -the=case is cut away at the upper end as shown at 1 in Fig. 1 to permit cartridges to be fed outwardly from, the forward side of the magazine; The side walls of the case are bent inwardly at the upper end as shown at 2 and 3 to form stops adapted to prevent .the cartridges from being forced outwardly through the upper open end of the case. Sight openings 0 are provided at intervals along the righthand side'of the case to show approximately how many cartridges arecontained -magazine to a firearm or the like, this guide wardly, the case being formed of pressed metal. The upper portion of the guide 5 is cut away so that the guide terminates at the plane 9 as shown in Fig. 3. The guide is provided with an opening 10 to receive a catch on the firearm to hold the magazine in position.

The lower end of the tubular case is closed by means of the closure shown in perspective in Fig. 7. This closure comprises a bottom portion 11 adapted to fit snugly into the cartridge case and a T shaped projection 12 adapted toclose the lower end of the guide 5. On opposite sides of the bottom closure are integral tabs 13 and 14 which bend upwardly at right angles and at their upper ends these tabs are bent outwardly so as to hook into slots 15 and 16 in the opposite walls of the cartridge case. The upper ends of the tabs 13 and 14 are bent outwardly only a suflicient distance to project into the slots in the cartridge case from the case when positioned in the slots. The bottom closure may be removed by pressing inwardly on the bent ends of the tabs 13 and 14 which are disposed in the slots 15 and 16 until they are nnhooked from the slots. The bottom closure is preferably formed of a single piece of sheet metal stamped and pressed into the form shown in Fig. 7.

A follower F is provided to engage the rearmost cartridges in the magazine as shown in Figs. 4 and 5 and interposed between the follower F and the bottom closure 11 is a coiled compression spring 1?. The follower F is provided with a transverse -portion 18 and with longitudinal portions 19 and 20. The follower is'forlned of sheet material and the longitudinal portions 19 and 20 are bent downwardly at right-angles to form flanges adapted to slide along the forward and rearward wallsof the magazine case. In order to engage the rear-most cartridges of each column of cartridges. as illustrated in Figs. 4: and 5, a raised portion 21 is formed on one side of the follower ,by providing a lateral extension on one side of the transverse portion 18 and bending extension into the form shown in Figs. 4 and 5, preferably by a stamping operation. As illustrated in Figs. 4 and 5 the final form of this raised portion comprises a bend or fold at 22, and 90 bends at 23, 24 and 25, the height of the raised portion being such that the raised portion engages the lowermost cartridge of one column when the lowermost cartridge of the other column rests on the transverse portion 18. In this way the impelling force of the follower, is applied substantially equally to each column of cartridges, thereby avoiding any tendency for the cartridges to wedge or bind. A tab- 26 is struck up from the flange 20 so as to extend outwardly through the slot 4 into the guide 5, the tab 26 being so positioned on the follower that it extends above the upper end of the guide when the magazine is emptyas shown in Fig. 3.

In Figs. 9 and 10 I have shown the magazine applied to a firearm of the type disclosed in my prior application, Serial No. 282,642, filed March 14, 1919 and also in'my applications Serial Nos. 297,282, 297,283, 297,284 and 297,285 filed on even date herewith. This firearm is provided with a frame 27 which has a channel 28 inits forward face adapted to receive the guide 5 of the magazine, the guide 5 sliding upwardly into this channel from the bottom. The firearm is provided with a catch 29 adapted to hook into the opening 10 in the magazine guide and hold the magazine in the position shown in Fig. 9. In this particular firearm the catch 29 comprises a part of a lever 30 which is pivotally mounted on the left-hand side of the frame 27by means of a circular lug 31 projecting inwardly from the inner side of the arm into a circular opening in the frame 27. This construction is described and claimed in my aforesaid application, Serial No. 297,282 and in so far as the pres ent invention is concerned it is sufiicient merely to state that the arm 31is normally urged in a clockwise direction by means of a coil spring surrounding the lug 31 so as to hold the catch 29 in the position shown in Fig. 9 and that in order to remove the magazine the arm 30 is shifted in a counter clockwise direction until the catch 29 disengages the magazine guide.

The breech action, which is described in my aforesaid application Serial No. 282,642,

comprises a bolt which has a large rearward portion 32 arranged to reciprocate to and fro in the receiver R behind the region of the magazine and a smaller forward portion 33.adapted to move to and fro above the magazine. As described in my prior application the action of the bolt is automatic and each time the bolt moves forwardly it forces a cartridge out of the magazine and carries it forward into the firing chamber. While the portion 32 of the bolt is above the magazine the lower side of the bolt extends into the magazine so as to prevent the foremost cartridge from being ad-' vanced by the follower to the uppermost position shown in Fig. 5. After the portion 32 of the bolt has been retracted to the position shown in Fig. 9 in the rear-of the magazine the foremost cartridge moves up into the position shown in Fig. 5 so that its upper portion is disposed in the path of the bolt.

'When the bolt moves forwardly the car- -my aforesaid application Serial No; 297 ,282,

comprises a sear 33 pivotally mounted at 34, a trigger 35 pivotally mounted at 36, a dis connector 37 disposed between the trigger 35 and the sear 33, and a yoke 38 surround= ing the upper portion of the tri ger and pivoting on the same shaft 36. spring normally urges the sear into engagement with the bolt and a spring 40 urges the disconnector 37 into the position wherein the projection 41 will engage the sear when the trigger is pulled to disengage the sear from the bolt. The yoke 38 is provided with an extension 42 which extends into a position above the guide 5 of the magazine where it is engaged by the tab 26 on the follower when the magazine is empty. When the tab 26 engages the end 42 of the yoke .the yoke isrotated in a clockwise direction into the position shown in Fig. 9 wherein it rotates the disconnector 37 in a counter clockwise direction against the action of the spring40 until the projection 41 of the dis connector is brought into such position that it will not engage the sear when the trigger is pulled. Consequently when the magazine becomes empty the parts are automatically moved into the position shown in Fig. 9 wherein the bolt is held in retracted position even though the trigger be pulled, until the magazine is detached from the fire arm.

In assembling my improved magazine the follower is first inserted through the open bottom of the cartridge case, the spring is placed in position and the bottom closure is then inserted into the position wherein the fingers 13 and 14 hook into the slots 15 and 16. .To attach the magazine to the firearm it is merely necessary to slide the guide upwardly into the channel guide in the frame 27, the catch 29 being automatically retracted due to the fact that its forward end magazine whereupon the magazine will either slide out by-gravity or may be manually detached.
