:Asa .cartridgecaisifed to the; deliveryj-opening by the rotor it; comes ;;intoz the "path of a rampi I9 secured to the body portion, thereby moving the cartridge rearwardly and after the cartridge passes through the delivery opening its rim or butt engages the cam 20 to'cause the cartridge to move forwardly into a cartridge holder 2| formed by spring clips secured to the body portion. 22

, designates a cartridge pick up in the form of a curved plate extending downwardly'through the delivery opening into the path of the cartridges on the rotor so that they will be guided upwardly through the delivery opening. The ramp l9 has an upwardly extending arm 23 which is recessed to form a seat for the forward end of the, cartridge when it is in the cartridge holder. Two pairs of spring clips are employed to form the cartridge holder 2| and between such pairs'are the cam plates 24 which cause the cartridge to belproper- 1y aligned with the bore of the gun as it is being ejected from the cartridge holder. g I,

Assuming now that it is desired to load the cartridge holder, the cover is removed; rendering the handle I! accessible, The operator now rotates the rotor 4 in a counter clock-wise direction until the locking spring I3 enters the slot or recess M of the rotor. The rotor is now stationary and the operator has both hands free to load cartridges into'the individual cartridge re- I .ceiving pockets of the rotor. Afterthe rotoris 1 7 ing 26 of the same diameter as the opening In in] the body portion of the casing.

, i 1, A cartridge loaded; the cover is replaced and the spring release l8 forces the locking spring [3 out of theslot M of the rotor, so that the spring I is now free to feed the rotor. 1 r

The casing is provided with any desired or conventional' means for aligning'it with the machine gun or rifle with which it'is used, such as for example, the slotted bracket secured to the side wall of the body portion of thecasing;

" 'When thecartrid'ge is moved forwardly in the holderthe seat 23 serves as aframp to tilt the forward end of the cartridgejupwardly so that it will enter the bore ofthe gun:

"'Ourpresent invention isparticularly adapted for the feeding of rim fire .22 calibre cartridges having an outwardly extending annular flange at its butt end.' The ramp l9 andcam-20 cause the cartridge'in the cartridge holder to have its butt or'rim in advance of thatof the cartridge beneath it, which is the next cartridge to be fed,

and thus prevents anyclogging of the magazine andinterruption in its feed. v

The rotor has an annular channel at itsperiphery into which the cartridge pick up extends.

As will be apparentthe magazine may be made in different sizes to provide any desired capacity of cartridges'. 1

, The cover or 1id preferably has a cent ral open- It will now be apparent that we have devised anew and usefurcartridge' magazine which embodies the features of advantage enumerated as desirable in thestatement of the invention and the above description, and whilewe have, in the;

presentinstance, shown and described apreferred embodiment thereof which will "give in practice satisfactory and'reliable results, it"is to be under ,stood that this embodiment is susceptible of modi ing individual cartridge receiving means at its periphery, means to cause a rearward movement of the cartridge as it is fed towards said opening, means to cause a cartridge in registry with said opening topass through it, and means to efiect a forward movement of a cartridge after it has passed through said opening.
