Description of the Preferred Embodiment
With reference now to the drawings, and in particular to FIG. 3 thereof, the preferred embodiment of the new and improved clip magazine for use in feeding rounds of ammunition to a firearm embodying the principles and concepts of the present invention and generally designated by the reference numeral 10 will be described.
The present invention, the new and improved clip magazine for use in feeding rounds of ammunition to a firearm, is a system comprised of a plurality of components. The components, in their broadest context, include side walls, front and rear walls, bottom walls, a supplemental upper plate, and an opening in the top wall. Such components are individually configured and correlated with respect to each other so as to attain the desired objectives.
More specifically, the central component of the clip magazine 10 of the present invention is a pair of similarly configured side walls 12. Such side walls are each formed with a rear edge 14, and a front edge 16. Such edges are vertically oriented and parallel with respect to each other. The magazine also has a top edge 18, and a tapered bottom edge 19. The top edge is formed with a step 20 which steps downwardly toward the front edge. In addition, the bottom edge tapers upwardly from the rear edge toward the front edge at an angle of about fifteen degrees from the horizontal, plus or minus about ten percent.
Next provided is a front wall 24 and a rear wall 26. Such walls are permanently secured to the opposite edges of the side walls. In addition, the front wall has a small projection 28 extending horizontally adjacent to the top edge. The elevational extent of the projection constitutes less than ten percent of the height of the side walls. It is secured to the front wall adjacent to the top edges thereof and fills the gap between the front wall and the front face of the existing magazine well. The projection is locked into the forward attachment of the previously removed floor plate fixed magazine. In addition, the rear wall extends from the bottom edge of the side walls upwardly to a region adjacent to the top edge thereof. It is parallel with the front wall. The rear wall is generally of thicker material than the front or side walls. The rear wall is stepped at the top. This step is to allow clearance between the clip and the existing inner structures of the firearm, to include but not limited to alignment lugs, bolt hold open devices, and other parts of the classic bolt action rifle. The rear wall is wider than the front wall to form symmetric tapers from the rear wall to the front wall. Note FIG. 6. Such tapers are at about ten degrees. The rear wall is also formed with a horizontal recess 30 adjacent to the top wall. Such recess has an elevational extent of less than about five percent of the height of the rear wall. The projection and the recess function together in securing the clip magazine to the bolt action rifle in which it is to be coupled.
Next provided is a bottom wall, or more accurately, a pair of bottom walls 34. Such bottom walls are formed by the inward bending of the bottom edge of the side walls. The inward bending of the side walls generates an enlarged opening 36 therein.
In addition, a supplemental upper plate 40 is provided within the space between the side, front and rear walls. Such supplemental upper plate is for the positioning of rounds of ammunition thereon. Included therewith is a spring 42 located between the plate and the bottom walls. The spring functions to urge the upper plate upwardly and, consequently, rounds of ammunition thereon upwardly for being fed into the chamber of the rifle.
Lastly provided is the opening 46. Such opening is at the top wall and includes inwardly directing lips 48 extending from adjacent to the upper edges of the side walls. These upper lips are at an elevation higher than the upper edge of the front wall and rear wall, and are formed to match the rifle's existing inner feed lips, when present, or the radius of the ammunition casing. As such, the lips will keep each round of ammunition from moving upwardly beyond the clip. Further, the lower orientation of the front wall and the rear wall will allow the movement of each round of ammunition forwardly into the chamber of the rifle 50 to which it is coupled during normal operation and use.
The present invention comprises a clip magazine which is used in older model military rifles in place of the original magazines in which each cartridge must be loaded through the top of the rifle. More specifically, the present invention has particular utility with the Belgian rifle FN Model 1949, as well as other auto-loading and bolt-action rifles that were not originally equipped with a detachable magazine. In rifles such as the FN, the rifle is hand- or clip-loaded with the magazine locked in place. The cocking handle on the right side is drawn back to unlock the action and compress the springs. Releasing the cocking handle permits the springs to drive the mechanism forward to chamber the top cartridge from the magazine and lock the bolt. A pull on the trigger fires the cartridge, and thus one shot is fired, the empty case extracted and ejected, the weapon cocked, and a new cartridge loaded into the chamber ready for firing on the next trigger pull. An individual pull is required to fire each shot on most of these weapons.
The present invention fits directly into the rifles, following the removal of the existing fixed magazine or floor plate, and although it is somewhat longer in length, requires no modifications to the weapon. It could be made in five, ten, and even twenty round sizes, with a block to modify them to hold only five, for hunting in states which have such limits. Typically, the clip would be approximately 53/4 inches long, 31/2 inches wide and one inch in thickness, and made of steel with tempered steel springs. The feed lips and tapered shape match the opening in the receiver, and grooves and ears fit on the bolt stop plunger and the release lever.
The present invention can be simply slipped into an existing rifle to obtain all of the benefits of such equipment. It not only eliminates the loading of the cartridges through the top of the rifle, but also does not require that each round is cycled through the action for removal, which is a very dangerous practice.
It is a common practice to permanently alter such rifles to allow them to accept a clip. This makes them non-standard equipment which is illegal in some states. This new clip fits directly into the rifle which makes it much more practical and should gain rapid acceptance.
As to the manner of usage and operation of the present invention, the same should be apparent from the above description. Accordingly, no further discussion relating to the manner of usage and operation will be provided.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of the invention, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by the present invention.
Therefore, the foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the invention.
