zines for Firearms; and I do hereby declare the following to be a full, clear, and exactdescriptionof the invention, such as will en- .UMTED STATES rAT NT onmnsnsn. a. L. ROSS, or "5mm nas'rm, senrnmf amenzmn Iron rim-Ems.

Be it known that I, CHARLES A. F. L.

Ross, a subject of His Majesty the King of' Great Britain, residing at Balnagown Castle, Ross-shire, Scotland, have invented certam new and useful Improvements in Magaable others skilled in the art to which it appertainsto make and use the same.

.This invention relates to magazines for fire arms and has for its object to provide a magazine of this nature which will hold the cartridges firmly without chattering when moved up and down, will .move them in planes substantially parallel to themselves, and present them in a position from which they can be with unerring certainty forced into the breech of the gun when they are to be loaded.

With thisand other objects in view, the. invention consists in the novel combinations of parts and-in the details of construction.

more fully hereinafter disclosed and par- 7 'ticularly pointed out in the. claims.

Referring .to the accompanying drawings forming a part of this specification in which like numerals refer tolike arts in all the views:-Figure 1 is a side e evational View partly in section of the breech ,portion of a gunprovided with my invention; Fig. 2 is a view similar .to Fig. v1 but showing the parts of the present invention. To the frame-4 is pivoted as at 5 a casin 6, best shown in 4, and provided wit 1 p h the pivot holes 7 e frame 4is provided with a lug 8 having a hole 9 adapted to register with the. holes 7, and to accommodate thepivot 10 of the casin 6, see Fig. 3-.

' '{I-o the lug .8 's pivots t .11- an arm 12, and on .the opposite side of said pivoted at "13 .a'. similar arm 14. .It'wibe observed that thepivots 11 and .13 -'do not Specification of Letters Patent.

Application filed March 5, 1910. Serial H0.'54-.7,447,

bu lets.

register with each-other as is plainly shown in Fig. 3. The arm 12 is also pivoted as at 16 to the lifter 17, and the arm 14 is pivoted as at 18 to the said lifter. It will also'be observed that the pivots 16. and 18 do not register.

It results that the arms 12 and 14 are free to swin around the pivots 11 and 13 as centers. An these two centers being located eccentrically to each other, it necessarily results that the pivots 16 and 18 will move in circles which are eccentric to each other. But sincethe lifter 17 is pivoted at 16 and 18 to the arms 12 .and .14,- respectively, it cannot swing around said pivots 16 and 18, and itis accordingly firmly held betweenthe arms 12 and14. The sa1d.lifter,howe ver,'may swing parallel ,toitself until the; 'ivots 1'6 and 18 Parmesan-nae, 1am.

from the structure now disclosed reach the positions, as in cated in dotted lines in Fig. 3. In other words, since the pivots 16 and 18 move in circles which-nearly substantially parallel to itself. It further results that the cartridges supported on said lifter move upward with the same and stantially parallel to themselves on a rlgid platform so that no matter how sudden the motion there .is an absence of an chatterin or wabbling of the extreme points of the To the lifter 17 is also ivoted as at 18 the rod 25 telesco' ing in t e tube 26 which is pivoted to the u 8 as at the polnt 27. A spring 28 surroun .the rod 25 and tube 26 and, therefore, normally forces the lifter 17 upwardly. The lug 8 may be suitably cut away as at 29 to accommodate the arm 12 and a similar cut away place may be provided on the opposite side for the arm 14.

Secured to the. casing 6 are springs 30 which are bent over as at 31 to e agethe cartridges and hold them in the .sai casmg, 'and the spring 26 normally the topmost cartridge up against theclip portions 3'1'of the spr1ngs30. The spring 28,.thex1efore, iess'es u wardly the lifter 17, the cartri ges, the c ips 31 and casing 6, tending to revolve the latter around its pivot 5.

After the said casing 6 has moved upwardly a distance sufficient for the barrel 1,'during its rearward motion, to pick up a cartridge as indicated in Fig. 2, the said casing is too high'to permit the contlnued rearward motion of the barrel and allow the latter to interlock with the breech block 2. Therefore, in order to automatically move the casing 6 out of the Way of the barrel it is provided with the cam piecehaving a cam surface 35 which is engaged by a straight surface 36 on the barrel during. the latters rearward motion, see Figs. 1 and 2.- The surface 36 on the barrel upon striking the inclined surface 35 of the magazine casing forces the latter downward into thedotted line position shown in Fig. 2 and thereby compresses the sprin 28. In the meantime the pointed end of t e cartridge enters the rear end of the barrel, and the rear end of opening of the barrel with an inclined surforces its rear end from between the .clips' face such as 45 located below the bore proper in order to accommodate the pointed ends of the cartridges.

The operation of the mechanism will be clear from the foregoinggbut may be briefly summarized as follows :Upon firing a cartridge the magazine being in the position indicated in dotted lines in Fig. 2, the barrel goes forward and the spring 28 forces the casing 6 together with the cartridges therein upward into the "full line positions shown in Figs. 1 and 2.- During this motion the arms 12 and 14 swing independently on their pivots 11 and. 13 and the lifter 17 moves upwardly parallel to itself furnishing a firm foundation for the cartridges thereby avoiding any'shaking or wabbling ofthe ends of the same. The barrel now having moved forward sufficiently a new cartridge is brought into position in the path the barrel will take upon its counter recoil, and as thebarrel returns itpicks up the topmost cartridge as indicated in Fig. 2,

31, and simultaneously causes the surface 36 to contact with the cam surface 35 and force the casing 6 downward again into the dotted line position shown in Fig. 2. As the topemasr "-most cartridge is removed from between the clips 31 the spring28 forces, the lifter i7 upwardly parallel to itself and with it the other cartrldg'es until the topmostremaining cartridge contacts with the clips 31. These actions are repeated as long as cartridges are p It is evident that instead of carrying loose cartridges in the magazine, as illustrated, cartridgescontained in the well known. clips may be loaded into the magazine bysimply forcing the clip portion down through the slots 4:0, whereu on the cartridges will occupy the same relative positions as those indicated.

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 invention and, there fore, I' do not wish to be limited to such features except as may be required-by the claims.
