1 Claim.
i This invention relates to magazines for fire- -v`arms" andV has for the primary object the provision ofi-a device of this character which will accommodate a large number of cartridges and iwill feflicien-tly feed the cartridges tothe gun asuSed-by the latter and is so constructed that it may be easily andquickly applied and removed` from the stock of the gun and may be readily filled or replenished with cartridges when emptied of the preceding loading.
With these andother objects in view, this in- `venticn: consists in certain novel features of construction, combination and arrangement of parts which i i fFigure'l' isa fragmentary vertical sectional view shwing aimagazine constructed in accordance with my invention and illustrating the same applied tc a gun stock.

Figure 15 is a plan view illustrating a retaining stud bolt for the tube.
Figure 16 is an exploded View showing a guide block for the tube.
Referring in detail to the drawings, the numeral I indicates a gun stock in which is formed a chamber 2 for the reception of a magazine and leading from this chamber is a passage 3 connecting with a tube 4 removably mounted in a bore 5 formed in the gun stock `and which bore opens outwardly through the end of the stock adapted for connection to the usual breech block of the gun (not shown). One end of the tube is externally screw threaded, as
f shown at 6, and projects beyond the end of the stock so that it may be threaded to the breech .block for eiciently connecting `the stock to the gun while the opposite end of the tube is internally screw threaded and communicates with the chamber 2. A stud bolt 1 is threaded intok the last-named end of the tube for the purpose of supporting within said tube and adjacent to an entrance 8 thereof a guide block 9. The block 9 is provided with a tapered face IIl underlying the entrance 8 for the purpose of directing cartridges through the tube received from the passage 3. The chamber 2 opens outwardly through the lower or under side of the gun stock for the partial reception of a magazine housing II.
The housing II includes a plate I2 oiset, as shown at I3, to form a spring chamber I4. The plate I2 is provided with a screw threaded socket to receive a screw threaded set bolt I5 carried by the gun stock for releasably securing the housing II in the chamber 2. A spring shaft I6 is rotatably supported by the offset portion I3 of the plate I2 and has removably and rotatably mounted thereon a driving plate I'I adapted to abut anges I8 on the plate I2. The other end of the shaft projects outwardly of the spring casing and is provided with angularly related faces on which is secured a ratchet gear I 9 engaged by spring pressed dogs 20 pivotally mounted to the offset I3 of the plate I3. Said last-named end of the shaft projects beyond the ratchet gear to receive a key or like device for rotating the shaft in a direction for winding a clock type spring 20 located in the chamber I4 and has one end secured to said shaft. The other end of the spring is connected to the driving plate by a medium which will be hereinafter more fully described. A finger piece 2| having a screw threaded shank 22 extends through the driving plate and threads to the shaft for the purpose of rotatably and releasably mounting the driving plate to the shaft. A protecting plate 23 is mounted on the shaft between the driving plate and the spring 20.
The flanges I8 on the plate are of spiral formation forming on said plate a spiraled chamber 24, the outer end of which communicates with the passages 3. The spiral chamber accommodates a maximum number of cartridges, as shown end' engaging a connecting block 28, the latter having a pin 29 extending a short distance into the coil spring. The coil spring cooperating with the block andthe abutment forms a follower of a yieldable construction. The follower operates in the spiral chamber and the block 28 thereof? is provided with grooves 30 to receive walls 3| of a slot 32 formed in the driving plate. The slot 32 is angularly disposed relative to the journal of the driving plate and opens outwardly through the periphery of said driving plate at one end and its opposite end terminates in a laterally eX- tending branch 33. The drive plate is connected 35', to the outer end of the clock type spring by a Y thereof is providedlwith relatively spaced aper- -tures 35, any one of which is adapted to receive a spring pressed pin 36`slidably mounted to the 'plate I2 for the purpose of holding the driving plate against rotation under the action of the springy 20. The pin^36 is equipped with a finger piece 31 having an offset 38 and mounted to the plate I2 is an offset 39. The offsets 38 and 39 when engaged will retain the pin 36 in a position disengaged from any one of the apertures of the driving plate, consequently freeing the driving plate for rotation under the inuence of the spring 20. By turning the finger piece the offset 38 may be disengaged from the offset 39 and when the pin is manually released it may enter one of the apertures 35 and lock the driving plate against rotation.
A stop pin is carried by the gun stock I for limiting the movement of the follower, that is, after said follower has ejected the last cartridge of the magazine into the gun proper or ring chamber thereof.
In operation, after the magazine has been loaded and applied to the stock, the pin 36 is re leased from the driving plate and as the gun is red, the cartridges are progressed into the gun by the action of the spring 20. A device constructed in accordance with the foregoing will eiciently operate to supply the gun with ammunition as needed and is capable of holding a maximum amount of ammunition obviating the necessity of the user carrying additional ammunition in the garment or the necessity of reloading the magazine at frequent intervals.
Having described the invention, I claim:
In combination with a gun stock having a chamber and an ammunition passage communicating with said chamber, a plate projecting into the chamber and having an offset to provide a spring chamber, means detachably securing the plate to the gun stock, a spring shaft rotatably supported in the spring chamber, a spring for rotating said shaft, a spiral flange formed on one face Yof the plate, a drive plate rotatably supported by the shaft and free to rotate relative thereto and contacting said spiral flange for cooperating therewith and with the first plate to form a spiral passage to receive ammunition and having communication with the passage of the gun stock, a follower slidable in the spiral passage, said drive plate having a slot opening outwardly through an edge thereof, a block having opposite faces grooved to receive the walls of the slot and connected to the follower, and means for releasably securing the drive plate against rotation.
