Device for rapidly loading rimmed cartridges into large capacity firearm magazines
First Claim
1. A device for rapidly loading a predetermined number of cartridges into a firearm magazine, said magazine comprising cartridge entry means, each said cartridge comprising a cylindrical body and a rim portion extending radially outwardly of said cartridge body, said rim portion being located at one end of said cartridge and said cartridge comprising a relatively heavy nose portion at the other end thereof, said device comprising a loader body, means to removably mount said magazine on said loader body, feed finger means mounted on said loader body, means to cause said feed finger means to move with a first predetermined motion to first cause a cartridge engaged at its said rim by said feed finger means to move laterally towards said magazine cartridge entry means and to thereafter cause said feed finger means to move with a second predetermined motion to secondly cause that same cartridge to move longitudinally through said magazine cartridge entry means and into said magazine, and said first and second predetermined motions being different from each other.

Abstract
An improved ammunition loading device designed for cartridges having radially extending rims, such as 0.22 calibre cartridges. The invention comprises a body having a spiral groove and a feed arrangement to drive the cartridges through the groove and into a magazine. A manual crank has an eccentric cam which operates two mechanisms alternately on each rotation of the crank. On half the rotation it operates a feed finger which inserts the next cartridge exiting the spiral groove into the magazine, and on the other half of that same rotation it advances the line of cartridges to present a fresh cartridge for insertion on the first half of the next rotation.

- 1. A device for rapidly loading a predetermined number of cartridges into a firearm magazine, said magazine comprising cartridge entry means, each said cartridge comprising a cylindrical body and a rim portion extending radially outwardly of said cartridge body, said rim portion being located at one end of said cartridge and said cartridge comprising a relatively heavy nose portion at the other end thereof, said device comprising a loader body, means to removably mount said magazine on said loader body, feed finger means mounted on said loader body, means to cause said feed finger means to move with a first predetermined motion to first cause a cartridge engaged at its said rim by said feed finger means to move laterally towards said magazine cartridge entry means and to thereafter cause said feed finger means to move with a second predetermined motion to secondly cause that same cartridge to move longitudinally through said magazine cartridge entry means and into said magazine, and said first and second predetermined motions being different from each other.
- 17. A device for rapidly loading a predetermined number of cartridges into a firearm magazine, said magazine comprising cartridge entry means, each said cartridge comprising a cylindrical body and a rim portion extending radially outwardly of said cartridge body, said rim portion being located at one end of said cartridge and said cartridge comprising a relatively heavy nose portion at the other end thereof, said device comprising a loader body, said loader body being formed with socket means for receiving said magazine, said loader body being formed with a spiral wall defining a spiral groove, said groove having a uniform radial thickness of a dimension larger than the diameter of said cartridge body but smaller than the diameter of said cartridge rim, said groove having a depth greater than the length of each said cartridge, said spiral wall being joined to said loader body at one end of its height and the other end of its height defining a plane which is positioned generally horizontally when said cartridges are to be loaded into said groove, whereby said cartridges may be placed randomly on said plane and will fall nose first by gravity and due to said relatively heavy nose portion into said groove upon shaking of said loader when said cartridges are on said plane, the length of said groove being greater than the sum of the diameters of said predetermined number of said cartridges to be loaded into said magazine, and means to communicate the radially outermost end of said spiral groove into said magazine cartridge entry means, whereby said cartridges may be fed out of said spiral groove and into a magazine positioned in said socket with said cartridge entry means of said magazine open to said spiral groove'"'"'s outermost end.
- 30. A device for rapidly loading a predetermined number of cartridges into a firearm magazine, said magazine comprising cartridge entry means, each said cartridge comprising a cylindrical body and a rim portion extending radially outwardly of of said cartridge and said cartridge comprising a relatively heavy nose portion at the other end thereof said device comprising a loader body, said loader body being formed with means for removably mounting said magazine thereon, manual crank means and means to rotatably mount said crank means on said loader body, said crank means comprising eccentrically mounted cam means, said device comprising means to feed said predetermined number of cartridges one by one into said magazine, said device comprising means to advance all of said predetermined number of said cartridges all at once to said feeding means, and said cam means comprising means to operate said feeding means to feed one cartridge into said magazine during a portion of each cycle of operation of said manual crank means and to operate said advancing means to advance all of the remaining ones of said predetermined number of said cartridges to said feeding means during another portion of each said cycle of operation of said manual crank means.
