Fremont, Farmington, Conn., assignor to Colts Inc., Hartford, Conn., a corporation of Arizona Filed June 19, 1967, Ser. No. 646,981 Int. Cl. F41c 25/02 US. Cl. 42-50 10 Claims ABSTRACT OF THE DISCLOSURE An economically disposable weapons supply magazine of plastic, having a driven follower mechanism to successively present cartridges for feeding to the firing chamber of an associated weapon, metallic component structure cooperatively related with the magazine to contain the follower driving forces, and protective cover structure for the magazine.
This invention relates to cartridge magazines for weapons, and more particularly to cartridge magazines which are economically disposable.
Cartridge magazines for weapons traditionally have been made of steel. Advances in the technology of lightweight metal fabrication have enabled industry to produce cartridge magazines of these metals, but these have generally been at least as expensive as the steel units.
It is an object of this invention to provide an economically disposable cartridge magazine.
It is another object of this invent-ion to provide an economically disposable cartridge magazine sufficiently durable to withstand long-term storage under various and extreme conditions and still be fully and substantially instantaneously serviceable when removed from storage.
It is another object of this invention to provide an economically disposable cartridge magazine sufiiciently durable to withstand abuses inherent in field usage.
It is another object of this invention to provide an economically disposable form-sustaining cartridge magazine of plastic which ensures bind-free feeding of cartridges to the weapon therewith associated.
It is another object of this invention to provide an economically disposable form-sustaining, high impact strength plastic cartridge magazine.
Other objects will be in part obvious and in part pointed out more in detail below.
In the drawings:
FIG. 1 is a view in perspective, partly exploded, showing one embodiment of the invention;
FIG. 2 is a side view, partly cut away and partly in section, of the embodiment shown in FIG. 1, assembled and showing spring means therein;
FIG. 3 is an end view in section, taken along the line 33 of FIG. 2;
FIG. 4 is a plan view in section, taken along the line 4-4 of FIG. 2;
FIG. 5 is a view in perspective, partly exploded, showing an alternative embodiment of the device shown in FIGS. 1-4;
FIG 6 is a side view, partly cut away of the embodiment of FIG. 5, showing closure (in phantom), load carrying, and follower and spring means;
FIG. 7 is a front elevation view of the embodiment of FIG. 5 showing a thickened body portion;
FIG. 8 is an end view in section, of the insert of the embodiment of FIG. 5 and FIG. 9 is a plan view in section, taken along the line 9-9 of FIG. 6, with the follower and spring removed.
Generic to the two embodiments of the invention described below is the concept of utilizing magazine body 3,453,762 Patented July 8, 1969 structure of form-sustaining plastic combined with metal components adapted to control the forces exerted by fully contracted follower drive mechanism.
Referring now to FIGS. 1-4 a magazine body of plastic having side, end and open base portions is shown generally by 112, with lips or fingers 113 also of plastic. A lightweight cover fits about the top and lip portion 113 of the body 112 to exclude contaminants therefrom, and to protect the fingers from damage. This cap may be attached by means of leg 103 depending from the cap and cooperatively fitting the aperture 105. A lightweight metal base support 117 and metal container or control means 107 fixed to the body 112 at the lower and open base end thereof by, for example, retainer studs 108 cooperatively receives a follower spring 109 and a follower 110. The spring can be compressed with the follower and then both trapped entirely within the cup formed by base 117 and container 107 and shown generally by 1 16 and retained therein by means such as, for example, pin or pins 111 inserted through the wall structure of the container 107. During such time as the follower and spring are maintained trapped within the cup, lightly biasin spring means 101 shown mounted at 102 in the cap 100 can be employed to keep cartridges in alignment within the magazine. Lanyard 106 may be grasped to pull pin(s) 111 from the cup 116, releasing the follower and its spring to bear against cartridges (not shown) in the magazine body 112, and to flip off the protective cover 100 from the body 112. The magazine is thus readily made serviceable from the posture of storage. When not associated with the cap 100, the aperture functions as the usual latch hole. Strengthening of the body 112 may be effected by ribs or grooves, or both as shown, or by any other suitable means.
Alternative to the embodiment just discussed and preferred, FIGS. 59 illustrate a unitry, cup-like plastic magazine body shown generally by 202 having side, end and base portions. Metal container or control section 201 including base support means 211 for the spring is inserted within the body 202 so that the fingers 203, in this embodiment forming an extension of the metal section, just protrude above the cup 202. The two bodies may be fastened together, for example, in part by rivets 208, and in part by retaining claws 213 which grip the plastic body 202 adjacent the fingers 203. A lightweight cover 200 is provided to fit around the top or lip portion, exclude contaminants from the magazine, and to prevent damage to the fingers 203.
The trapped-spring embodiment provides means to contain the follower and its spring entirely apart from the plastic magazine. This structure relieves the plastic material of internal stresses during storage. A number of plastics are known which can be formed into cartridge magazines such as 112 and as configured will be capable of carrying the full magazine spring forces at a low stress level. Polycarbonate material has properties which are satisfactory for this purpose.
The alternate embodiment of the invention as disclosed herein can utilize plastic materials which are less expensive that polycarbonate but which do not have properties that would allow them to contain the full magazine spring force at an acceptable stress level. Such a material would be high density polyethylene. In this embodiment, all the spring forces are constrained to act at all times within a path of metal and throughout the structure, from base to fingers.
Conventional follower spring means having good shelf life properties may be utilized with both embodiments. The trapped-spring magazine is made somewhat deeper than is standard to permit further compression of the magazine stack without additional stressing of the spring.
Both magazines utilize metal base elements to support the follower spring.
Disclosure of polycarbonate and high density polyethylene for use in the invention is merely suggestive of the variety of choices of plastics available, and is not intended or understood to be in any way limiting of the materials chosen for the article of the invention. Both of the plastics have high impact strength properties and are readily formed.
No limitation to a particular material for the cap or cover is intended beyond the requirement that it be protective of the magazine fingers, lightweight and economically disposable with the magazine.
The subject invention provides a cartridge magazine which can be quickly and easily formed from inexpensive materials and which meets stringent storage and use requirements heretofore satisfied only by metal and which plastic magazine is at the same time truly economically disposable. Economical long-term storage is also provided by use of either of these novel magazines.
