CARTRIDGE MAGAZINE.
Application filed March 29, 1922. Serial No. 547,643.
To all whom it may concern:
Be it known that I, HEINRICH ORTGIES, a citizen of the German Republic, residing at Erfurt, Germany, have invented certain new and useful Improvements in Cartridge Magazines, of which the following is a specification.
My invention relates to a cartridge magazine and in particular to a magazine of the kind for use in automatic pistols and the like.
Magazines of the above stated type essentially consist of a box or case made of sheet metal Or the like and having a bottom plate at one end insertedtherein and rigidly connected therewith by soldering or by means of rivets. In the latter case the said plate is usually provided with extensions or lugs projecting from its inner face and having holes for the reception of the rivets.
soldered cartridge magazines are objectionable because of the excessive cost of manufacture; and riveted magazines are also objectionable for the reason that the extensions or lugs on the inner surface of the bottom thereof do not afford a suitable abutment for the lifting spring to properly rest against. Furthermore said lugs reduce the space in the magazine available for the reception of cartridges, so that the length of the magazine must be correspondingly increased for a predetern'iined number of car tridges.
Heretofore the idea of providing in the magazine a bottom plate with a flat and smooth inner face has been contemplated, it
is true; but the suggestions hitherto propagated for a practical realization of the problem have, as far as my knowledge goes, proved a failure on account of the complicated construction and the excessive cost involved thereby.
The object of my invent-ion is to simplify the construction of a cartridge holder or magazine of the above stated type, to thereby reduce the cost of its manufacture and at the same time to produce an article of superior quality and value.
With this object in view and according to my invention the bottom end of the magazine box or case is recessed at its two opposite 1 corners so that two lateral flanges are formed, said flanges projecting from the two opposite side walls of the case, which latter is usually of rectangular cross section with the front wall curved to semicircular shape. The longitudinal edges of the bottom plate are correspondingly recessed or cut out so as to form projections at its two ends adapted to snugly fit into the recesses of the bottom end of the case. The said lateral flanges of the latter, however, have a length greater than the thickness of the bottom plate so that, when the plate is fitted in place, they project beyond the outer surface thereof in order to be bent inwards to securethe plate in its seat.
In this manner a structure is obtained the two individual parts of which can easily be manufactured and readily be assembled to constltute a'magazine which is of a certain reduced length with relation to its capacity of housing a certain number of cartridges, A particular advantage, moreover, resides in the smooth and even inner face of the bottom plate affording an adequate abutment for the spring to rest upon, so that the latter is enabled to work freely and Without erking.
Accordingly my invention consists in the construction and arrangement of parts as will be hereinafter more fully described, shown in the accompanying drawings, and specifically claimed, it being understood, that changes in the form, proportion, sine and minor details may be made within the scope of the invention as claimed without departing thereby from the spirit or sacrificing any of the advantages of my invention.
In the drawings, Figure 1 is an elevation of the box or case with its bottom end recessed, Figure 2 is a view of the said bottom end, Figure 3 is a perspective view of the bottom plate, igure 4- is an elevation similar to Figure 1, but with the plate shown in Figure 3 attached to the bottom end, Figure 5 is an elevation as shown in Figure 4, but with the projecting ends of the lateral flanges bent ove 1 the bottom plate, Figure 6 is a view similar to Figure 2, but with the bottom plate attached and the ends of the lateral flanges bent over as in Figure 5, and Figure '7 is a side view of the magazine shown in Fig. with the upper end broken off.
a is the box or case of, customary shape and 7) is the bottom plate. As will be seen in Figures 1, 3 and 5 the bottom end of the case a is recessed at its two opposite corners to form steps and (Z, respectively, and the plate I) is correspondingly recessed at its two side edges for the reception of the two lateral flanges g oi the case a when attached to the latter. The length of the lateral reeesses of the plate Z) is exactly the same as the width or" the flanges 57 so that they snug ly fit together. On the other hand the projections e and f of the plate Z) properly fit the steps 0 and (Z in the bottom end of the case a when the plate assumes its place at the bottom of the case, as shown in Figures t'and 5. To secure the plate I) on its seat the projecting ends of the flanges g are bent or turned over as shown in Figure 5. In this way a rigid and snugly fitting connection between the bottom plate Z) and the case a is obtained.
The work required to cut the case a and the plate to shape, to assemble the parts and bend the flanges 9 over the plate I) may be carried out with any suitable machine tool, so that the magazine can be cheaply manufactured and sold at a low price.
Having now described and ascertained the nature or my invention and in what manner the same is to be performed, what I claim A cartridge magazine, comprising a sheet metal box or case having its lower end cut away at the opposite corners thereof to form avpair of seats at said corners and a pair oi depending, lateral flanges between said seats, and a bottom plate havingits opposite side edges cut away to form a pair of projections at opposite ends of the plate forengagement in said seatsand a pair of recesses between said projections immediately in line with and of exactly the same length as the flanges to permit the latter to fit therein; said flanges having a height considerably in excess of the thickness of said plate, so as to enable their free lower end-portions to be bent inwardly and upwardly against the under face ofthe plate, thereby to rigidly secure the plate to the case. r v
In testimony whereof I affix my signature.
