Be it known that I, NmroN W. H. BROWN, a citizen of the United States, residing at Trenton, in the county of Mercer and 'State l of New Jersey, have invented certain new and useful ImprovementsA in Box-Maga-A Y zinesfor Firearms; and I do hereby'declare the following to'be a full, clear, and exact description of the invention, such as will '10 enable others skilled in the art to which' it appertains to make and use the same.

g My invention relates to magazines of the box Atype especially adapted for ire arms,I

and has for its object to provide a magazine may be loaded with" great rapidity, (and which will possess other advantages to be' A d and are adapted torest; when the follower described below. n With these and otherv I construction and' combinations off vparte more fully` hereinafter disclosedlanud -par; ticu'iarly pointed out in theeelaims.

Slidingly tting the said casing 4 is the inner casingv13Y provided at each end with the slots 14 through Vwhich the stems^7 pass. Fitting within said innercasing -13 but not carried thereby, is the cartridge follower 15 controlled by the the bottom I7 of said inner casing. The

said follower 15 has downwardly extending lends or lugs 18 having openings 19 into which' lit the Tshaped. lugs 20', as best shown-in Figs. 1, 5 and 6..A The heads21 of these .lugs slide in said slots 14, as shown,

The inner casing 13, as best shown in Fig. 3,; is further' provided with 'slots 28,'4 one on each side to llmit the movement of the stems 27 therein, when the block 23 is moved.'v e outer casing`4 isfurther provided on ch side with 'afbayonetslot 30 havingl openings 31 adapted tc'yrbef-enteredy by the-said stem vportions 27 of thethumb-screws26, and on magazine whereupon the said inner casing 100 ends of the stems 7, as illustrated ilrlig.A 1: 70-

The top portion 35 of the innercasingis beveled oif as shown in Fig. 1, in order that the cartridges'may not catch thereon when the ,inner casing' is being pushed home.

'.Theoperation of my improved box magazine is as follows z-The outer casing 4 is normally fixed tothe fire arm by the ythumb catch y11, and istherefore not intended to be detached frm the arm except at rare in,- tervals when it is necessary to clean the magazine. The follower 15 lifts the cartridge is fired, the heads 21 carried' by :said

occupyl a'position about even with the bottoniof the opening33 in the outer casing`4, and cartridges may be inserted one at a time through `thesaid opening 33 until a column ofcartridges occupies the said outer casing 4f When the magazine has been thus lled the bottom casingnlyff may now be forced pasti-he column of cartridges in the outer screws will contactl with 'the cam surfaces' 32 whereupon the slide block 23 willbe autoy matically forced .against the .tension of vthe Asgring 25 toward the leftv. yas seen in 'Fig/"1.

A soon as the opening 31 is passed, however, the said spring 25 will force the block.

thegslot 30 and the inner casing 13 to be sewhereupon the heads 21 ofthe follower will .Contact with the stems 7 of the set screws 6,

fromfvthe top of the magazine by the bolt 2' As the car s ring 16 forces the follower upwardly, and.l

the inner casing and thereby steady the saidv follower and cartridges. Also, the shoulders the lugs or bosses 5 so as to prevent the said thumb screws from working loose. Further, when the inner casing 13 is lowered into the position shown in 'F ig. 3, the upper ends of its slot take against they heads 21and the said heads rest upon thesaid stems 7, and therefore the said thumb screws 6 prevent vthe inner casing from being withdrawn and possibly lost.

., The floor 17 of the inner casing is conveniently held in place as by pins 40, and

need not be removed exceptupon very rare n occasions.'

The thumb screws 26 may be setup tightly whileA permitting the inner'casing to move freely at all times. Further, the walls of the inner box 13 extend a distance over the slide block 23 in order to make the movement of the 'slide certain and accurate. It, therefore, follows from the foregoing that by merely pushing forward or toward the left, as seen in Fig. 3, the locking thumb screws 26 until they reach the limit of their forward movement, and then drawing the inner casing downwardly, the magazine may be unlocked and loaded, while the mere pushing of the said inner casing 13 upward,will bring the Xparts ofjthe loaded magazine into operative relationz The pushing of the inner casing home will place the spring 16 under tension, and thec'artridges will be held inthe magazine bythe turned ,over lips of the outer casing 4, as illustrated, the uppermost cartridge lying inthe path of the bolt 2 ready to be forced forward into the chamber of the barrel. When the last cartridge is red, the follower rises finto the path of tle `bolt and stopsthe motion of the latter.

The thumb catch 11 preferably extends into the trigger guardfas shown, soV that it may belreadily operated when desired.

IIn tassembling' the parts, the follower is first inserted intothe inner casing 13 and the lugs 20 are inserted in the holes -19 through the slots 14 of the said inner casing.

The advantages of my present invention will be apparent when vit is rememberedthat the usual detachable magazines are mainly 'used in arms having a solid breech and side ejector. Therefore, the only means of loading is by detaching said magazines from the arm and `ltting the cartridges into them one at a time. Not only is this a tedious opera- 'tion,'but it is liable to'require considerable time at a crisis when such time is of thegutmost valuex In my '.device, on the other hand, Vit will be -seen that the loading is effected without detaching the' magazine at v all. urther, it is well recognized that'the most practical type of box magazine is the typeknown as the fixed type, while, on the other hand, the great objection to a detachable magazine asl proved, in actual practice, is the fact that the box being separable from tervals for the purpose o imanes the arm is very liable to getll'ost. Now, my

out the disadvantages of the latter. In other words, although the outer casing 4 is not positively fixed to the arm, yet it need not be removed therefrom except at long in! i cleaning. Also, my ientiremagazine is so constructed that it canfbe ,taken apart Ventirely by hand without the use of any tool.

It is obvious that those skilled in 'the art' may vary the details of construction and the arrangement of parts without `departing from the spirit of my linvention, and thereJ fore I do not wish to be limited to the above disclosure except as may be required by the claims.
