MAGAZINE FOR FtaEARMs'.

SPECIFICATION t .ippnmon met March 4, 190.2.

Be it known that I, CHARLES H. A. F. L. ROSS, a subject of the King of Great Britain,

Shire, Scotland, have invented new and useful improvements in Magazine-Firearms, of which the following is a specification.

This invention is applicable tov various forms of bolt and machine guns.

It relates particularly to the construction of the magazine, wherein a supply of cartridges is stored and from which they are fed to the gun, and in a device employed in conjunction therewith by which the magazine can be latched out of action and the cartridges therein held in reserve while the gun is loaded singly.

The invention is illustrated in conjunction with the form of bolt-gun breech mechanism which is patented to me in my United States Letters Patent No. 643,984, issued to me February 20, 1900, entitled Improvements in magazine bolt-guns.

In the accompauyingsheet of drawings, Figure 1 shows a side view, brolen away on the line X X of Fig. 3, of a portion of the breech of a firearm including the magazine' and showing the parte in position for feeding cartridges from the magazine. Fig. 2 is a side view, broken away on the line X2 X2 of Fig. 4, of the same parts and showing the magazine cut-O and the cartridges therein held in` reserve while the gun is loaded singly before each discharge. Fig. 3 is a transverse Fig. 2, showing the magazine cut-0E The receiver 1 of the gun is a hollow forging, and the gunbarrel 2 is threaded to its guideways and locking -shonlders for the breech-bolt 3, which may be of any desire-d construction. `There is a passage-way th rough the under sideof the receiver, vthrough which each cartridge as it is fed from the magazine 4can pass fromthe magazine into the breechchamber inthe receiver, when it will be enplace and locked for tiring when the breechbolt is driven forward. The receiver has a forming part of Letters Patent No. 747,777, dated December 22, 1903.

Serial No. 96.603. (No model.)

passage: way in the upper side, through which cartridges can be inserted singly before each tiring, when the magazine is empty or the feed therefrom is cut o. In the form illustrated the magazine is loaded .by inserting the cartridges through the receiver. The magazine has a rear wall and two side walls which extend forward suiciently to hold' the cartridges in position, in conjunction with.

inwardly-projecting lips 4 along the inner upper edges of the side walls, and a follower 5, which is pressed upwardly against the cartridges inthe magazine by a spring 6 bearing on the framework of the gun. The uppermost cartridge in the magazine rests against the inwardly-projecting lip on one side of the magazine. When the parts are in a position for feeding from the magazine', the reareud of this uppermost cartridge will be partially in the path of the breech-bolt, and when the breech-bolt is driven -forward this =artridge will also be driven forward, the forward end will-"enter` the chamber of the gun, and when it has been driven forward sufficiently to be free from tb,e lips by `which it was held down in the' magazine against the upward pressure of the spring it will rise fully into the receiverand in line with the bolt and gun-barrel.

The magazine is of sufficient width between its side walls to hold two rows of cart-ridges,

-the rows being staggered with respect to each other, so that the cartridges in the two rows `will be alternateIybrOUght into engagement with a lip on one or the other side of the magazine and into position to be driven? forward and out of the magazine by the breech-A bolt.

That part of the magazine which carries the inwardly-projecting lips is guided from the framework of the receiver by lugs 7, pins 8,

and a mortise which receives a downwardlyprojecting tongue 9 on the magazine. The magazine has a limited vertical movement between two positions. Its upper position is shown in Figs.. 1 and f3, and in this position the- 'cartridge immediately under y the inwardly-projecting lip ispartially within the receiver and in the path cti-the breech-bolt, so that it will be fed from the magazine into the breech end of the gun when the breech- IOO bolt is driven forward. The upward pressure of the spring against the follower which is transmitted through the cartridge to the inwardly-projecting lipsnormally holds the magazine in this position.

The lower position of the magazine is shown in Figs. 2 and 4. In this position the cartridge immediately undell the inwardly-projecting lip is below the path of the breechbolt in the receiver, and the cartridges will not De fed from the magazine when it is in this position. The magazine is brought from the position of Figs. l and 3 to this position, in which the magazine-feed is eut off by pressing downward on a knob 10 on the side of the frame. The stem of this knob passes through the stock and is attached to the magazine.v

Vhen brought to this lowered position, a latch 1l engages a catch 12 on the rear wall of the magazine and retains it. This latch is pivoted to the trigger-guard, and a knob 13 thereon projects within the trigger-guard. By pressing against this latch the magazine is released, and it will rise into position for feed- I ing from themagazine.- I do not limit myv self, however, to the form of magazine which is illustrated, for it can be readily adapted to magazines in which the cartridges are in a single row and to detachable magazines by providing means for latching the magazine in both positions.

What I claim as new, and desire to secure by Letters Patent of the United States, is

The combination with a receiver and a breech-bolt therefor, of a magazine with side walls which is guided in the frame and has a limited movement toward and from the receiver-chamber, inwardly-projecting lips at the upper edges of the side Walls, a knob for withdrawing the magazine to its position away from the receiver-chamber, a latch for retaining the magazine in this latter position, and a spring-pressed follower bearing on the frame by which the cartridges in the magazine are pressed against the inwardlyprojecting lips of the side walls of the magazine and the magazine is thrust toward the receiver-chamber upon the release of the latch, the walls of the magazine being outside the path of theA breech-bolt in both positions, and the cartridge immediately adjoining the lips in the path of the breech-bolt in the position of the magazine toward the receiver-chamber, and outside the path of the breech-bolt in the position away from the receiver-chamber, substantially as described.
