' Another objector the invention is to provide a novel magazine construction which is simple and elficient in operation and which can be readily manufactured and assembled. I a

.In carrying out these objects the present invention provides-a novel magazine construction which is adapted "to be mounted on' a' firearm, preferably in a recess formed in the firearm, which magazine includes a housing preferably having. an'outer surface to conform or blend into the outer contour of the firearm. The magazine is held in position by a yieldable detent whichcan permit the rnag'a zine tobe quickly inserted and replaced with a minimum of efr'ort'. n n 7 safety feature in that it will yield under undue pressures The construction also provides a inthe firearm and vent the firearm to relieve the pres- Themagazine of the present invention is "simplein. construction and comprises a rotary carrier mounted in a bore in the housing and provided on its surface with longi-- tudinally extending recessesfor supporting and retaining cartridges forfsolely rotation therewith whereby jamming due to sliding action of the cartridges in the magazine is eliminated. The housing which-encloses the carrier is i preferably provided with a single longitudinally extending opening which faces the firearm, when the magazine is in position thereon, and has guide means adjacent the opening for supporting a cartridge in aready position in which it can be delivered to; the firing chamber of the fireai'rr'r.

i A-feature of the invention resides in the fact thatthe guide' means is-preferably in the form of longitudinal ribs loeatedon each side of the opening and has a'space there between for receiving the cartridge from the carrier and has means for holding the cartridge against lateral movement therefrom so that the magazine can bepre loaded.

The rilis, however, arejprovided with means whereby the 1 cartridge can be released therefrom by longitudinal movement of the cartridge therealong as it is fed to the firing chamber.

, The carrier is normally urged'to'rotatein a directionin which the cartridges are fed from the recesses to-the opening. Adjacent the opening ther'e is provided deflect? iing meanswhich move the cartridges laterally outof-thef l recesses and into the space between the guide ribs.

Another feature ofthe invention resides in the fact that the magazine" may accommodate rim-type cartridges by being provided with a counterbore' adjacent the end of the carrier into which the rims may pass so that the cartridge lies flat in' the carrier and can be readily con trolled in its rotary movement with the carrier. 7

A still further feature of the present invention resides in the simplicity of the construction of the magazine which enables it to be readily manufactured and assembled at a relatively low cost. i

.Other'features and advantagesof the invention will be apparent from the specification and claims when considered in connection with the accompanying drawings in which:

The rotary magazine of the present invention has particular use inhandheld firearms such as pistols and rifles to supply a'plurality of cartridges thereto and can be mounted thereon in various locations as may be practical and convenient.

In the herein illustrated form of the invention a magaz'ine 10 is inserted in a recess 11 provided in'the frame 12 of a' 22 caliberpistol of the typedisclosed in my Patent No. 2,899,767 havingabarrel 13' disposed in a lower position on the frame. The magazine, which is positioned above the barrelof the pistol, is designed to supply a large number of "cartridges thereto. As shown in FIG. 2, the recess 11 opens into'a transfer chamber 12a within the frame of the pistol-adjacent the firing chamber =14 formed in-"the barrel 13 which is closed by a sliding breechblock 15 which carries the usual extractor and ejec- In accordance with the preferred formof the invention; the magazine comprises-a housing 16 having a cartridge carrier 17 'rotatably mounted therein. The magazine is held m the recessby a detent means herein illustrated as a spring-pressed ball 18c arriedby the frame 12 of the,

pistol and engaging an aperture orrecess-1'9in the end of the magazine. This permits the magazineto be readily inserted and removed from the pistol and also provides a safety factor in that it permits the magazine to move outwardly upon building up of abnormal pressure in the shaped to provide a camming action to assist the deflector rotation of the carrier to slightly more than one r'evolutioh, the slight excess being sufiicient to cause the pusher to move thelast cartridge into ready position.

Further, the meansfor limiting the rotation of the carrier may include amanually operable means wherebythe-carrier "can be rotated against the urging means to without themaga'zine interfering with its use, and without transfer area",-whereby said area is vented to reduce the pressure. r

While the magazine" maytake various shapes, it is preferred to have'the housing shaped "or contoured to blend with the" surface of the firearm adjacent the recess. In the herein illustrated form ofthe inven'tion-the housing hasa curved outersu'rfacewhich, as shown in FIGS. 1 and 2, blends into the contour of the firearm to provide aconstruction which is balanced, can bereadily handled interference in and S I I The housing as herein illustrated comprises, a cylindrical the-sighting-of the pistol by-the sights S member 20 forming side walls and a pair of'en

'd walls j

21, 22. The housing ispr'ovided with a longitudinal-bore 23 therein. While the housing may be fabricated in many ways, it is at present preferred to form the end wall 21 integral with the side walls 20 to provide a casing and to form the end wall 22 as a separate member to be inserted into position to close the casing and be pinned in place to facilitate-the assembly as will be explained.

The

end walls

21, 22 are provided with

aligned apertures

24, 25 which form bearings for rotatably mounting a shaft 26 secured to the carrier 17. One end 26a of the shaft 26 projects beyond the end wall 21 and the other end of the shaft is carried by the aperture 25 in a sleeve 27 forming a continuation of the aperture 19 in the end wall 22 so that the carrier is mounted coaxially with the bore in the housing as shown in FIGS. 2 and 3.

On the surface of the carrier are a plurality of longitudinally extending cartridge-receiving recesses 28, herein illustrated as being ten in number. The recesses are so spaced with respect to the wall 20 of the bore 23 of the housing that cartridges 29 received in the recesses will be retained therein for solely rotating movement with the carrier by said wall.

If it is desired to have the magazine accommodate cartridges having rims 29a, the bore of the housing can be counterbored at 23a adjacent the end of the carrier to permit the rims to ride therein while the cartridge is supported in the recess.

In accordance with the preferred form of the invention, the housing has a single elongate opening 30 in the side wall through which the cartridges pass into and out of the magazine. This opening, as shown in FIGS. 2 and 3, is in that portion of the side wall adapted to face the firearm so that the magazine is completely closed to foreign matter when in position on the firearm.

As herein illustrated, guide means is provided on the magazine for guiding the cartridges laterally from the carrier into a ready position in which the sliding breechblock 15, as it moves to close the firing chamber 14, will move the cartridge into the firing chamber.

While the guide means may take many forms, in the herein illustrated form of the invention it comprises a pair of

ribs

31, 32 each located on a side of the opening to project therefrom and receive the cartridges therebetween as they are fed from the carrier. The carrier is normally urged to rotate in the direction of the arrow A in FIGS. 3 and 7 to deliver the cartridges carried thereby seriatim to the guide means. While this rotating means may take many forms, in the illustrated form of the invention this means comprises a helical spring 33 having one end 33a secured to the carrier and the other end 33b secured to the removable end plate 22. Preferably, the spring surrounds the sleeve 27 and an aligned boss 34 on the carrier and is supported thereby.

In order to deflect the cartridges from the recesses into the space between the ribs in response to the rotation of the carrier, the present invention provides an annular groove 35 in the surface of the carrier intermediate the ends of the recesses and provides a deflecting finger 36 on the housing at the far edge of the opening 30 projecting into the groove so that as the cartridges are moved by the carrier into a position overlying the opening the defleeting finger will cause them to move laterally and into the opening and into said space between the ribs. To facilitate this lateral movement, the trailing edge 28a of each of the recesses is curved or shaped as shown in FIG. 3 to cooperate with the cartridge engaging the defleeting member in a manner that continued rotation of the carrier will cause'the cartridge to be moved laterally away from the carrier and out of the recess. As herein illustrated in FIG. 7, as the first cartridge is moved laterally, the carrier will move the next cartridge into position behind the first cartridge and push said first cartridge into the space between the ribs at the rear end thereof. The ribs, adjacent the rear end thereof, are provided with lips 40 which engage the cartridge and hold it against further lateral movement and in a ready position in which the lower edge of the cartridge is disposed to be engaged by the sliding breechblock 15. It will be supported on the breechblock as shown in FIG. 6 and when the breechblock moves rearwardly to Withdraw and eject the spent cartridge casing, the rim will drop to a position to be engaged by the breechblock and fed forwardly toward the firing chamber. The cartridges so held by the guide means will prevent further rotation of the carrier under the urging of the spring until the first cartridge has been moved from ready position. When this is accomplished, the carrier 17 again rotates to feed the next cartridge to the opening.

In order to move the last cartridge in the magazine to ready position, the magazine of the present invention is provided with a pusher member 41 which is carried by a wire bail 42 pivotally mounted on the carrier for relative movement with respect to the carrier. The pusher member lies in the last recess on the carrier and when the carrier has fed the last cartridge into the opening, con- 7 tinued rotation of the carrier will cause the pusher member to move into the opening as shown in FIG. 3 so as to apply pressure to the last cartridge and maintain it in the ready position in the guide means. Preferably the pusher has a conical end 41a which will cause it to retract in the event that it is inadvertently engaged by the sliding breechblock. 7

. In order for the pusher to accomplish this, it will be seen that the carrier must rotate through slightly more than one revolution. In the herein illustrated form of the invention, the means for controlling the rotation of the carrier for slightly more than 360 comprises an arm 43 rotatably mounted on the end 26a of the shaft extending through the end wall 21. The arm 43 has a stop pin 44 passing through the arm so as to have ends 44a, 44b

-- projecting from the faces of the arm. The end 44a of the stop pin cooperates with a slot 45 in the end plate 21 and limits the movement of the arm to a relatively small arc. A stop arm 46 is fixed to the end 26a of the shaft and projects outwardly to engage the other end 44b of the stop pin so that the rotation of the shaft 26 will be limited,

under the action of the spring, to a complete revolution of the shaft plus the amount of rotation permitted by the slot 45 in the end disk through its cooperation with the arm 43 and stop pin 44.

' 1 pusher.

The cartridge in the guide means is adapted to be moved longitudinally of the ribs by the sliding breechblock and fed to the firing chamber. The forward ends of the

ribs

31, 32, as shown in FIGS. 6 to 8, are devoid of the lips 40 so that the cartridge, as it moves longitudinally of the ribs, is freed from any retaining action of the lips and can be released from the magazine. Preferably, the forward ends of the rib members are provided with downwardly deflecting

cams

47, 48 for guiding the nose and rim of the cartridge downwardly, as shown in the dot and dash lines in FIG. 7, into position to move into the firing chamber of the pistol.

The stop arm 46 can also function as the means for rotating the carrier 17 in a reverse direction against the action of the helical spring when it is desired to load the magazine. In this case, with the magazine released from the pistol, cartridges are fed longitudinally of the guide ribs into position in which they overlie the opening in the housing. The cartridges are then fed through the opening, the first cartridge lying in the recess adjacent the The carrier is then rotated against the action of thespring by the arm 46 to bring the next recess in line with the opening and the next cartridge is deposited in the recess. This continues until all of the recesses, except the one carrying the pusher, are filled with cartridges and the last cartridge is then inserted into ready position in the ribs and will be held in this position by the lips and the pressure of the cartridge at the opening. Thus, the magazine will hold ten cartridges. Since the magazines can be preloaded, one may have a supply of magazines on hand and quickly and easily interchange them with the pistol to provide for a rapid fire operation of the pistol.

The magazine of the present invention is simple to construct and easy to assemble. As shown in the drawings,

the cylindrical member 20 forming the side walls and the end wallzl are formed integral. The ribs '31, 32 are secured to the cylindrical member to project therefrom and form, a casing unit. The shaft 26 which has the arm 43 and stop arm 46 mounted thereon is inserted'throughthe aperture-24- inthe wall 21. The carrier 17 is positioned on the'shaft and is pinned thereto by pin 49. The torsion spring isput in position and has one end secured to the carrier, and the other end secured \to the end plate 22, and

end 26b of the shaft is inserted in the bearing aperture I in sleeve 27 on the end plate 22. The end plate is rotated sufiiciently to tension'the torsion spring and is then inserted into the end of the casing and pinned in position by pin '50 or any suitable securing means, completing the magazine assembly.

, Thus, it will be apparent'that ithe'elements which can be readily machined or otherwise formed and assembled will very economically produce magazines for use with firearms.

Further, itwill be noted that inasmuch as the movement of the cartridge in the magazine is solely a rotary move- .ment and there is nolongitudinal sliding movement as might wipe ofi wax from the cartridges or lead from the 'usual lead-nose of the cartridgethat the building up, particularly in cold weather, of obstacles to the movement of the cartridge is substantially eliminated, and a smoothworking, effective cartridge supply is provided for the firearm. Variations and modifications may be made within the scope of the claims and portions of the improvements may be used without others.
