5 Claims.

This invention relates to improvements in magazine rifles, and more particularly to a rifle having a plurality of magazine tubes adapted to hold ammunition, and mounted for rotation within the forearm of the rifle stock, whereby a box or more of cartridges may be held in the magazine at one time.

An object of my invention is to provide an improved magazine rifle having a rotatable magazine group comprising a plurality of magazine tubes adapted to be filled through an opening in the side of the forearm of the stock, together with means for advancing the next filled or loaded magazine tube as the last cartridge has been fired from the preceding tube.

A still further object of my invention is to provide an improved magazine rifle formed with a rotatably mounted magazine group consisting of a plurality of magazine tubes adapted to receive cartridges, together with means for rotating the magazine group to present a filled magazine tube after the cartridges in the preceding magazine tube have been fired, and means for indicating to the user which magazine tube has been emptied, and which tube is still filled with cartridges.

Another object of my invention is to provide an improved magazine gun or rifle formed with a rotatably mounted magazine group consisting of a plurality of magazine tubes having movable closures at their ends, and a single cooperating spring pressed plunger for forcing the ammunition or cartridges up into the rifle breech in position to be fired.

Another object of my invention is to provide 7 an improved magazine rifle having a rotatably mounted magazine group in the forearm of the rifle stock, said magazine group consisting of a plurality of magazine tubes supported upon rotatable disks at their opposite ends, and having means for rotating the magazine tubes to bring the next adjacent full tube into position for feeding the cartridges into the breech of the rifle to be fired after the previous magazine tube has been emptied, together with means for filling the several magazine tubes through a filling opening in the side of the forearm of the stock adjacent the rear end of the rifle barrel.

A further object of my invention is to provide an improved magazine rifle having a rotatable magazine for ammunition or cartridges, which will be highly efficient in operation, and quite inexpensive tomanufacture and produce.

Other objects will appear as the description proceeds.

Like characters of reference are used throughout the following specification and the accompanying drawings to designate corresponding parts.

In carrying out my invention, I provide a magazine rifle having a barrel I, a stock 2, and connected forearm 3. The barrel I is provided with the usual rear sight 4 and front sight 5, and is closed at its rear end by means of the usual breech block, firing pin mechanism, and trigger 6.

As will be seen from the drawings, the forearm of the stock is considerably enlarged to provide room to receive the rotatably mounted group of magazine tubes. The magazine group will consist of any desired number of magazine tubes 1, but for purposes of illustration I have illustrated my improved gun equipped with five magazine tubes, said tubes being supported at their forward end by the disk head 8 rotatably mounted upon the pin 9, and the rear end of said tubes being supported in the disk head In which is rotatably mounted upon the pin II. A tubular plunger i2 is mounted where it can slide into and out of each tube 1 as said tube is brought into position to deliver its contents to the breech of the rifle. The internal diameter of this tubular plunger is slightly greater than the external diameter of the cartridges used in the rifle while the external diameter of the tubular plunger is slightly-less than the internal diameter of each tube 1. With= in the tubular plunger I2 is a coiled spring 4| which exerts a pressure against a plunger head-14 locking member 24 is supported on the under surface of the barrel l, and extends downwardly along side of the ratchet plate or disk 20, and is provided with an inwardly extending locking pin 25 which is adapted to be received in one of the locking notches I9 in the periphery in the front disk head 8. The ratchet plate or disk has an enlarged aperture 26 which will be alined with the uppermost magazine tube 1 in the magazine group. The ratchet plate or disk 20 also has a radially extending ear 27 positioned diametrically opposite to the operating pin 2| adapted to engage the lower end of the resilient locking member to force the locking pin out of engagement with the locking notches in the front disk head. jv The-ratchet plate or disk 29 is provided on its rear surface at a point adjacent the operating slidable within the tubular plunger. Under norma] conditions the plunger head i4 is located within the open end portionof plunger l2 but when the tubular plunger is forced into a tube 1 containing cartridges, said cartridgeswill be received by plunger I2, the head l4 being thrust back within plunger l2 against the action of spring l3. Consequently when the plunger I2 is pressed backwardly toward the breech toone extreme position, all of the cartridges contained Within the tube 1 in which the plunger is seated,

will be received by the plunger and will, in turn,

receive pressure through head M from thecompressed spring I 3. In this connection attention is directed to Figure 8 showing a portion of the plunger l2 broken away to disclose the spring 13 therein, the plunger head l4, and-one cartridge remaining in the tubular plunger at the outlet end thereof prior to-being ejected into the breech. The plunger l2 will be supported in the rifle in the customary manner.

V Positioned upon the pin 9 immediately in front of the front disk head 8, is a hanger plate or disk I6, provided with a central aperture 11 which receives the pin 9, and with an enlarged aperture l8 adapted to line up with the magazine tube 1 which is in the uppermost position immediately under the barrel of the rifle. The hanger plate or disk I6 is secured to the rifle barrel I and serves to support the forward end of the magazine group.

The rear end of the single magazine 10 is transversely of the barrel I, in a correspondingly shaped slot and cooperates with the forwardly extending flange 13 on the hanger disk I 6 and an arm of the resilient locking member 24, later to be described. The arm of the member 24 is placed between the flange 13 and the cross bar I2 and the several parts are held together by means of the set screws 14. A plurality of looking notches l9 will be formed about the periphery of the front disk head 8, the purpose of which will be hereinafter described.

Mounted upon the forward pivot pin 9 immediately in front of the hanger plate or disk I6, is a ratchet plate or disk 20, the same being provided with an elongated slot 23 adjacent its central portion, and with a radially extending ratchet plate operating pin 2|. This pin is threaded at its outer end and adapted to receive the threaded operating cap 22 which extends through an elongated slot 23"in the right hand side of the forward portion of the forearm 3. A resilient pin 2l, with a dog 28 adapted to seat into one of the locking notches [9, when the locking pin 25 on the resilient locking member 24 has been withdrawn from the adjacent locking notch.

As before mentioned, the rear disk head [0 is rotatably mounted upon the pin ll, said pin also supporting immediately behind the rear disk head ID, a rotatably mounted closure disk 29 having an enlarged aperture 30. This aperture is adapted to be alined with the uppermost magazine tube when the gun is in readiness for firing, and to be moved toward the right to aline with the filling aperture 3| when the magazine is to be loaded. Aperture 3| is formed on an angle through the side of the rear end of the forearm 3, whereby cartridges-may be inserted through said filling aperture and through the aperture 30 in the closure disk 29, to be received within the magazine tube 1. g

A bell crank operating lever 32 pivoted at 33, is attached at its forward end to the closure disk 29, and the opposite end of the said bell crank lever is connected to the bracket 15 secured to the lug 16 on the under side of the barrel I. The rear end of the bell crank lever extends upwardly along the side of the rear end of the barrel, whereby the closure disk will be positioned with its aperture 30 in alinement with the filling aperture 3|, when the bell crank lever is moved toward the rear of the rifle stock. It is to be understood that during the filling of the tubes 1 the plunger 12 is retracted forwardly from the magazine so that rotation of the group of tubes will not be interfered with. After the several magazine tubes have been filled with cartridges, by moving the bell crank operating lever 32 forwardly to an approximate vertical position, the aperture 30 in the closure disk will be caused to be alined with the uppermost magazine tube 1.

Positioned about the magazine group adjacent the rear ends of the tube 1, is a band carrying numbers to indicate the number of the magazine tubes which underlies the particular number. The tube indicia band 34 may be viewed through the sight opening 35 formed through the side wall of the forearm 3. The user of the gun will be constantly advised of the amount of ammunition he has remaining in the magazine tubes which have not been fired.

From the foregoing description it will be apparent that the operation of my improved magazine rifle will be as follows:

To load the rifle, the spring plunger I2 is completely removed from the upper magazine tube 1, and the bell crank operating lever 32 is pushed rearwardly, which will aline the openings or aperture in the closure disk 29 with the filling aperture 3!, whereby the alined tube 1 may be comlength of the filled tube 1.

pletely filled with cartridges. As soon as the magazine tubehas been filled with cartridges, the operating pin and cap secured to the ratchet plate or disk 20 of the forward end of the magazine tubes is pressed inwardly causing the ratchet plate or disk 2!] to move to the opposite end of the slot 23 thereby causing the ear 2'! to force the locking pin 25 on the resilient locking member 24 out of engagement with the notch IS in the edge of the front disk head 8, and'with the same inward movement will cause dog .28 to seat into one of the locking notches i9, and by pushing down on the operating cap 22 the magazine tubes will be rotated so that the next adjacent tube will line up with the filling opening in the rear of the forearm, whereupon it may be filled with cartridges, and this procedure repeated until all the magazine tubes have been filled. When the magazine tubes have been filled with cartridges the plunger I2 is thrust back into the magazine tube 1 aligned therewith. As the internal diameter of this plunger I2 is slightly greater than the external diameter of the aligned cartridges in said tube 1, it will be obvious that this backward movement of the tubular plunger will result in the aligned cartridges being received within the tubular plunger. This will result in these cartridges pressing back against the plunger head I4 and causing spring I3 to be placed under compression within the tubular plunger. Ultimately the tubular plunger will extend through the Following this operation the bell crank operating lever 32 is pushed forwardly thereby covering the rear end of all of the magazine tubes 1 except the one uppermost in the group containing the tubular plunger filled with cartridges. Thus by operating the bolt mechanism, the cartridges will be fed by spring pressed head 14 upward through the magazine extension and in position to be inserted within the breech of the barrel I. After all of the cartridges have been ejected from the uppermost tube 1, the plunger I2 is withdrawn from the magazine so as to release the group of tubes for further rotation to bring another filled tube 1 into alignment with the plunger [2. Thereafter said plunger is again pressed backwardly to receive the aligned cartridges in the path thereof and to place its spring under compression whereupon the foregoing operation is repeated. It will be obvious that the normal position for holding the rifle when filling, will be with the barrel pointed downwardly toward the ground, thereby overcoming the possibility of any one being accidentally shot during the loading operation.

While I have described and illustrated one form of my improved magazine mechanism for rifles, it will be understood that I do not intend to limit myself to this particular construction, as it will be readily apparent that many minor changes in detail of construction may be resorted to without departure from the spirit of the invention. As this magazine is designed to be used on several different makes of rifles which will require minor changes in order to be attached to difierent makes of rifles.
