7 Ciaims.

My invention relates generally to firearms and particularly to a machine gun pistol involving a cartridge magazine enabling setting the pistol to fire continuously automatically until the supply of cartridges is exhausted, or to fire a predetermined number of the cartridges less than the total number thereof which are in the magazine in the mentioned continued automatic manner, or to re single cartridges automatically each time the trigger is pressed, and an important object of my invention is to provide an automatic pistol of the character indicated which is small in size and light in weight, and can be carried in a holster.

Another important object of my invention is to provide a cartridge magazine for an automatic or machine gun pistol which is small and compact and narrow and lies chieiiy Within the plane of the handle of the pistol, and which does not protrude laterally beyond the sides oi the pistol.

Another important object of my invention is to provide a pistol of the character described above which contains a magazine arranged so that the cartridges are moved from an initial position in the magazine at right angles to the barrel to a position in alignment with the barrel, in such a way as to positively preclude jamming of the cartridges during the firing of the pistol.

Other objects and/advantages of my invention will be apparent from a reading of the following description in connection with the drawings, wherein for purposes of illustration I have shown a. preferred embodiment of my invention.

In the drawings:

Figure 1 is a longitudinal sectional view taken through the pistol in a plane which lies slightly to the left of the longitudinal center of the pistol so as to show the interior mechanism of the magazine and the interior mechanism of the pistol per se.` l i Figure 2 is a left hand side elevational view of the magazine.

Figure 3 is an approximately central transverse sectional view through Figure 2 taken approximately on the line 9-9 and looking toward the right in the direction of the arrows.

Figure 4 is a top plan view'of Figure 2.

Figure 5'is a perspective view of the spring containing drum of the magazine.

. Figure 6 is a perspective view of the latch plate securing screw.

Figure 7 is a perspective view of the latch plate.

Figure 8 is a perspective view of the cartridge follower. H

Referring in detail to the drawings, the numeral 5 generally designates a Vpistol body on which is mounted a slide and the barrel, and which includes a butt portion 6 and the handle portion'i. Just forward of the handle is the opening 8 through which the cartridges are fed from the 'magazine 85 into the ring chamber.

Depending from the underside of the front end of the barrel is a pair of keyhole-shaped mem- 'bers 34 which are arranged'to be positioned in front of similarly formed members 25 on the slide when the barrel and the slide are assembled; and from the rear end of the barrel 20 depends the block 35 with the opposite side grooves IQ which engage the barrel locking pins I8 for locking the barrel engaged with the slide and with the body of the pistol.

The member 28 contains on its front end the extracting ring 36 and lnteriorly the firing pin 3l which is surrounded by an actuating spring 38 which normally retracts the ring pin inwardly through the opening in the front end of the member 28 after striking the cartridge 39. The body of the ilring pin has a slot 40 in which is a retaining pin 4| relative to which the ring pin is slidable. 'Ihe rear end of the firing pin which is normally retracted by the spring 38 extends into the hollow part of the butt portion of the body of the pistol as indicated in Figure 1 where it can be struck by the upright portion 62 of the hammer 63 which is L-shaped in form as shown and slidably mounted on the hammer mounting pin M which carries the spring t5 pushing the same forwardly. The underside of the rear and horizontal portion of the hammer 43 has a depending triangular dog 65 which is engaged by a part of the hammer lock 41. Pivoted to the trigger as indicated at 6l is a springpressed trigger latch 68 which is notched to engage With a dog on the trigger latch for the hammer lock which immediately engages the hammer lock release latch 65 which is pivoted in the body of the pistol as indicated at l0 and has a rounded nose 'H engaging in a rounded notch in the depending part 1| of the hammer lock 12 which has the spring 'F3 positioning the same forwardly and downwardly as shown in Figure 1, a lug on the bottom of the hammer lock being engaged with the upper end of the spring 13. The' machine gun latch is slidably mounted ina slot in the forward part of the hammer lock and has a depending fork between the tines of which is engaged the rounded nose on the upper part of the spring-pressed lever 'it which is pivoted in the body and has its lower end and the rear side thereof .engaged by the spring# pressed trip which is L-shaped in form and has the stem 8| working in the tube 82 which is mounted on the rear of the butt of the pistol body and is normally out pressed by the spring 83 so that a tendency exists to .tilt the machine gun latch forwardly.

The magazine which is shown in Figure i and in Figures 2 through 8, inclusive, is generally designated 85 and comprises a sheet metal or other suitably fabricated shell the main portion of which is cylindrical and has the forward tangential extension 80 and the rear upward extension 8l, and the horizontal wall 88 extending between these tangential extensions and abutting the underside of the body part 5 of the pistol. The wall 88 has a slot 8S through which passes the hooked lug 90 on the lower side of the body part for the purpose of engaging the hooked head 9| of the magazine latch 92 which ispivoted as indicated at 93 between the side walls 963 and 95. The lower part of the latch 92 is accessible through an opening in the front end of the magazine casing 85 as indicated in Figlires 1 and 2. A boss or lug 96 on the rear wall portion of the upward extension 81 is arranged to engage a notch 91 in the rear wall of the opening 8 in the body through which-the extension 8l extends into position to deliver the `car tridges into the ring chamber of the pistol.

Transversely spaced guide strips 98 and 98 spiral radially outwardly from the point 99 to form the cartridge channels, which spiral until they meet the point |00 where they join the forward wall of the upward projection 8l. Radially outwardly of the last-mentioned portion of the guide strips isl the radially outward channel which is defined by the most radially outward portion of the guide strips and the curved wall |0| of the magazine casing, the last-mentioned channel leading directly into the lower part of. `the extension 8l.

The cartridges 39 lie across the space between the opposed guide strips and in the channels dened thereby so as to have theirvaxes approximately at right angles to the longitudinal axis of the bore |02 of the barrel. Beginning at the lower part of the extensions 81 the channel is gradually turned from its transverse to a longitudinal position,l so as to gradually turn the cartridges as they are fed therein from the mentioned transverse position to a position in which they are in longitudinal alignment with theaxis of the bore of the barrel, and in this position ready to be received into the tiring chamber. The smooth and even and gradual travel and change of position of the cartridges as they are fed into the firing chamber or into position to be deposited into the firing chamber positively prevent the occurrence of any jamming of the pistol during its operation.

It will be observed that the engagement of the wall 88 of the magazine casing with the barrel latch keeps the barrel latch positively locked so that disassembly of the barrel or -loosening thereof cannot occur while the magazine is in position. It will be observed that left hand pulling oi' the magazine latch 92. will disengage the same from the hook member 90 and that when this disengagement has taken place the maga-- zine may be pulled away from vthe pistol and another magazine substituted.

Approximately centrally within the guide strips 98 Iand centrally of the magazine casing and,

journaled in bosses on the side walls 96, is thev axle |03 which has engaged therewith as indicated at los the web los of the drum generally designated |06 which contains on oppositeI sides of the web |05 the spiral springs |07 and |03, respectively, which are attached to the axle by the respective pins |08 and |09 at their inner ends and have their outer ends pinned as indicated at I I0 to the interior of the circumferential portion of the drum. The drum has extending approximately normal to the periphery thereof` the channel-shaped member |I| which communicates with the opening ||2 adjacent thereto to permit the insertion in the drum of the follower which is generally designated H3 and which is bifurcated as-indicated at H9 to provide legs ||5 and ||6 which go on opposite sides of the axle as indicated in Figure 3 when the follower is inserted through the opening ||2 by passing the same through the channel Ill, from which channel the transverse head |I`| extends 4through the extension 8`| and into the firing chamber of the pistol. One end of the drum |06 is provided with a latch disk ||9 which is located in an opening in the left side of the magazine and is provided with a peg |20 to engage a hole in a latch plate to be described and is additionally provided with holes |2|.

The peg is to be engaged with the hole |22 in the latch plate |23 which has on its circumference the catch |24 which engages the latches to be described, the disk |23 also being provided with holes I254to correspond with the holes I2 I which holes selectively receive pins |26 on the head of a screw |21 which is threaded into the end of the axle |03 as shown at |09. I

On diametrically opposite sides of the opening in the wall 913 in which the structure described immediately above is located are pivoted as indicated at |28 and |29 the 10-shot latch |30 and the ZO-shot latch I3I. The l0-shot latch |30 is arranged to be swung to a position to engage the catch |20 on the disk |23, which disk |23 is pinned to the axle |03 by the pins |26 which pass into the end of the axle, so that with the lO-shot latch |30 set, the gun can be ired only ten times subsequent to the point at which the latch is set. With the latch |3| -similarly set and the latch |30 not set, the pistol may be fired twenty times from vthe point at which the latch is set. With the latches |30 and I3! disengaged, full automatic machine. gun firing of the pistol to empty the magazine completely may be carried out, as well as single shot emptying of the magazine. The magazine is intended to hold fifty cartridges, although a greater or a less number may be arranged for.

It will be observed that the magazine need be no wider than the length of the cartridges used or not substantially so, so that the magazine need not be considerably wider and may be narrower than the thickness or width of the pistol and be of such dimensions to be not greatly larger than an ordinary trigger guard, if desired, so that no l 2,180,722 other than that herein described for illustrativeA purposes.

Although I have shown and described herein a preferred embodiment of my invention, it is to be definitely understood that I do not desire to limit the application of the invention thereto, and any change or changes may be made in the materials and in the structure and arrangement of the parts, within the spirit of the invention and the scope of the subjoined claims.
