Definitions
- This invention relates to a cartridge magazine for a firearm and a method for making such a magazine, and is more particularly related to such a magazine and method wherein the magazine is arcuate in shape and has a body preferably formed from a single piece of metal.
- Such a magazine is used to contain ammunition, such as a series of cartridges, which are fed one at a time by spring means into a firing chamber of a weapon. The spring means maintains pressure on the ammunition to force each cartridge in to the firing chamber, and when spent to deliver the next round into firing position.
- Ml 6 rifle or carbine An example of a firearm using a magazine is the Ml 6 rifle or carbine, which has become a standard rifle in the United States weapons arsenal and in other western countries.
- M16 weapon family such as the M16/A1, A2, A3 and A4, which are the primary infantry rifles used by the U.S. military and 15 NATO countries since the early 1960s. These weapons use a magazine of the type disclosed in this application embodying the present invention.
- such a magazine is arcuately shaped, and has a substantially rectangular cross section with parallel opposed longer sides defined by the height of the cartridge arranged between parallel opposed shorter sides defined by the width of the cartridge.
- One end of the magazine is closed with a removable base plate, and the other end is open to permit a cartridge in juxtaposition to the firing chamber of the weapon to be placed in firing position.
- such a magazine is fabricated from steel rather than plastic or aluminum, as the magazine is subject to heat and substantial stress when it is used in the field.
- the magazine is preferably curved toward the barrel relative to the point of insertion into the firing chamber.
- the magazine has a keyway formed in one of its thinner sides to train and direct the cartridge in a proper firing position for entry into the firing chamber of the weapon.
- the magazine is formed by appropriately bending multiple pieces of metal and spot welding the pieces together.
- Ciener US Pat. 5 ,461 ,811 which discloses a machined magazine body
- Chesnut US Pat. 4,586,281 for a magazine adapted for use with various styles of weapons.
- the arcuate magazine device embodying the present invention is strong and fabricated from steel to withstand field stress and has a smooth keyway and interior permitting free travel of a round from the magazine to the firing chamber of the weapon. These features are accomplished by using fabrication means which eliminate wrinkles and rough surfaces in the magazine, as well as selecting welding points which do not interfere with movement of the shell by the magazine follower mechanism.
- the magazine blank is deep drawn from high carbon steel, preferably having a Rockwell harness of 34-38 RC, so that the piece will not bend too easily, but not so hard as to make the material brittle.
- the magazine blank is designed so that only a single seam is necessary to form it, and so that the keyway is free of welds or wrinkling or similar encroachments.
- This fabrication requires a metal pressing operation which draws and forms the magazine including the keyway in a single operation, preferably using a 600 ton press (but a lesser press could possibly be used) with an upper pressure pad having a male form arbor, and top male form block and bottom female form block.
- the top male form arbor presses down on the magazine blank pinched between the upper pressure pad and the lower pressure pad with about 5500 lbs. PSI of pressure while the female form arbor resists the downward draw movement with about 9000 lbs. PSI and thereby forming the keyway and one of the short sides in the bridge of the magazine.
- Two lower pressure pads also serve as the curved surface across which the blank is formed as the blank is drawn down between the lower pressure pads. If inadequate pressure is applied, the keyway fails to form. If excess pressure is applied, the metal tears.
- the male arbor has pilots for locating the watch holes in the curved side of the magazine blank.
- pilot holes preferably perform the function of keeping the blank in place during the draw and form operation and the wiping operation.
- the edges of the form opposed to the keyway are used to weld close the magazine body by means of one or more additive welds, but the position of the weld could be elsewhere, so long as it doesn't interfere with the keyway and it does not adversely cause wrinkles or rough surfaces on the interior of the magazine when formed.
- This draw and form operation creates a magazine body oriented in the shape of a "U", with the keyway forming the base of the "U".
- Ribs may be added to the body to remove any wrinkling of the interior of the magazine and these ribs also add strength to the magazine and support the shell as it moves through the magazine.
- an inner flap is formed and an outer flap is formed running substantially parallel to the keyway enclosing the magazine and in position for welding.
- a robotic welder may be used to make the weld on the edges of the blank remote from the keyway, and this weld must follow the curvature of the magazine. After the blank is fully formed and welded into a single piece, a spring and follower is inserted into the closed magazine, and the base plate is applied to close the lower edge of the magazine.
- Another object is to provide an arcuate magazine which is fabricated in one piece.
- Another object is to provide a body for an arcuate magazine which is closed by additive welds.
- Another object is to provide an arcuate magazine for a weapon which may be heat treated with nitride or the like to provide a hardened finish.
- Another object is to provide an arcuate magazine which has a substantially smooth interior substantially free of wrinkles and rough surfaces, particularly in its keyway.
- Another object is to provide an arcuate magazine which is welded closed on an edge remote from its keyway.
- Another object is to provide a method for fabricating an arcuate magazine which is drawn and formed into a blank having a central keyway, sides depending from the keyway and edges remote from the keyway for welding the blank closed.
- Another object is to provide a method for fabricating a blank for an arcuate magazine having a keyway which is formed and drawn by means of high pressure applied to both sides of the blank.
