Application tiled October 5,-1893.

To all whom it may concern.'

Be it known that I, GEORGE W. CHA-nDLER, a citizen of the United States, residing at Manhattan, in the county of Riley and State of Kansas, have invented new and useful Improvements in Firearms, of which the following is aspeciication. l

Myinvention relates to magazine-firearms, and has'for one of its objects to provide such a firearm embracing a plnralityf cartridgechambers arranged to supplya common race and means for preventing the cartridges in the several chambers from interfering With-or crowding the cartridges passing up the race, and thereby rendering the mechanism inoperative.

' Another object of the invention is to provide a magazin e-lirearm embracing a plurality of cartridge chambers so constructedthat they may be simultaneously increased or diminished in length by the movement of a single part to adapt the gun to fire cartridges of different lengths.

Another object is to provide a magazinegun the mechanism of which is as a whole simple, compact, and durable and is therefore not liable to get out of order in use.

Other objects and advantages of the invention will be fully understood 'from the folowing description and claims when taken in conjunction with the annexed drawings, in whichy Figure l is a longitudinal section of a portion of my improved firearm with the shutter of the magazine-chamber and the shutter ol one of the subchambers shown as open. Fig. 2 is a detail longitudinal section With the breech-bolt in its retracted position. Fig. 3 is a transverse section taken-in the plane indicated by the line 3 3 of Fig. l. Figs. 4, 5, and 6 are enlarged transverse sections taken in the planes indicated by the lines d 4, 5 5, and -i H, respectively, of'Fig. l.

In the said drawings similar letters designate corresponding parts in all of the several views. I

' My improved firearm embraces a barrel A andstock B of 4common form and is provided with the usual opening a for the escape of empty shells and the usual breech-bolt C for' shoving cartridges into the breech end of the vbarrel Vas the cartridges are presented and closing said breech.y The breech-bolt is arranged in a suitable guideway and is moved through the medium of alreciprocatory operating-slide D, with-which it is connected by a latch E, as best shown in Fig. 9. Said latch is in the form of a bell-crank lever, and it is 1 fulcrumed at b in a recess in one sideof the Abreech-bolt and comprsesa rear armc','hav

ing a lateral branch c', and a forward arni d, having a lateral branch e. Incident to then forward movement of the breech-bolt C and slide D the latch E rests in the position shown in Fig. 2-that is to say, the branch e of the arm d rests in a notchf in operating-slide D and the branch c of arm c rests on a longitudinal ledge or bearing g.` y Now when the operating-slide D is moved forward the arm c ofthe latch resting on the bearing g will prevent the arm d from rising out of the notch f of the slide, and in consequence the bolt will be carriedA forward with the slide. The parts are so arranged that the operatingslide D has a slight forward movement after the breech-bolt has assumed its closed position, and the ledge or bearing g is of such a length that the latch-arm c will reach the forward endl thereof coincident with'the bolt reaching its closed position. Such slight forward movement of the operating-slide D after V.the breech-bolt has reached its closed posi- 'lease the bolt, and will then move the latch and the bolt rearwardly. The breech-bolt is provided with an ordinary or other suitable IOO chambers H, designed for ,the reception of.

vertical tiers of cartridgesf-afterthe manner shown in Fig. 1. These subchambers II in the preferred embodiment of the invention are formed by slightly-curved rear walls m, slightly-curved forward1 walls n, and sh utters p. The rear walls m are fixed to the side wall of the chamber F, while the forward `Walls fn, which are preferably channeled to better hold the forward ends of the cartridges against lateral deflection, are carried by a slide I, which is arranged in a guideway-q in the wall of chamber F and. is designed to be adjustably fixed in position by athumbscrew fr or other suitable means. By reason of this construction the length of the subchambers II may be readily increased or diminished to enable them lto receive and properly guide and deliver cartridges of various lengths to the race leading up to the barrel of the gun. This is obviously an important advantage, since it permits of the use of cartridges 0f various lengths in the gun. I prefer to fix the rear walls m of the subchambers H with respect to the stock as shown and described; but it is obvious that when desired the front walls may be fixed and the rear walls made adjustable-to increase or diminish the length of the subchambers.

l The shutters j) of the subchambers are connected in a hinged manner to the stock B,'so as to enable them to swing downwardly and outwardly, and they are designed to be secured in their closed position by suitable `latches s, as shown. At their inner sides they are each provided with spring-backed plungers or followers t, which have for their purpose to press the cartridges downwardly and positively feed the same tothe race.

J is the race, which is disposed below the several subchambers H and extends up to the breech end of the barrel, as shown.l

K 'are spring-pressed beveled detents,which project up from a fixed part K' which forms a portion of the floor of the race., at points below the rear walls m, of the subchambers Il and at corresponding intervals along the forward portion of the race, and L is a reciprocatory cartrid ge-f eedin g bar, which is arranged alongside of and flush withfthe fixed part K of the stock and forms part of the floor of the raced and is provided at intervals with springepressed beveled detents M. The detents M of the reciprocatory barL are so disposed that when said bar is in its lowermost or rearward position they will each of the stocks` rest slightly in rear of one'of the static)"naryAv detents ligand when said bar lis movedf0r-' tions slightly forward of the next forward sta-f tionary detents. It follows from this that with the several subchambersI-I filled with cartridges and the lowermost cartridges bearing at their heel'sngainstthe stationary detents vbelow the walls'm of thesubchambers H a full forward movement of the feed-bar L will carry each of'the lowerxn-ost cartridges forwardly from one detentl'fto the next forward detent K. In this way the cartridges arel fed in succession and step by step toward the breech end of the barrel. The final movemovement 'from the forward stationary det-ent K to the breech end of barrel A-is effected bythe spring-pressed tongue N on the feed-bar L, the said tongue, like the detents K M, being adapted to yield and allow the cartridges to pass over it andthen spring up and engage the rear end of the cartridges after the manner shown in Fig. 2. By reason of the feed-bar L being arranged fiush with the xed part K of the stock and .serving in "conjunction with the same to form the floor of the race it will be seen that said feedbar does not take up any part of the race and consequently permits. of said race being made of a size but-slightly larger than the diameter of the cartridges. It will also be observed M being both arranged at the lower side of the race gravity assi-sts the cartridges in remainino in position in advance of said detents. v f

In order to prevent the'cartridges in the several subchambers H from interfering with or crowding the cartridges passing up the inoperative, I provide hinged` or pivoted gates P at the lower ends of the 'rea-1 walls m of the two forward subchambers II. These gates P whenthe subchambers H are tridges rest in a pendent'position and consequently do not'interfere with the lowermost cartridge of each tier assuming a position on the floor of the race J and againsta detent K projecting therefrom. When, however, the

the cartridges that were the lowermost of the rear and middle tiers will assume a position tively, of said middle and forward tiers forwardly and upwardly into a horizontal position and in that way trap the cartridges inthe middle and forward compartments. ward movement of the feed-barL a cartridge `will be placed below the gates itwill'be seen that cartridges will be eifectually prevented from leaving the middle and forward chambers H until the rear chamber is exhausted and that cartridges will be effectually prevented from leaving the forward chamber ll. until the middle chamber H is exwardly to the full extent they will assume posiz ment of the cartridges-ethat is to say, thethat by reason of the sets of detents K and,v

feed-'barL is moved upwardly and forwardly,

below the middle and forward tiers, respecand inso doing will press the gates P P, and hence IOO IOV

race J andv thereby rendering the mechanism filled with car-- At every vforrgo' haustcd. It follows from this that the cartridges will be fed in regular succession from` ing the momentum which is imparted to them by the Forward throw ofthe feed-bar L, I pro-,

vide the upper wall ofu'that portion of the race J in advance of the subchambers H-wit-h spring-pressed shoes Qrwhich, impinging against the cartridges, serve to prevent them from moving a greater distance than the throw of the feed-bar and serve to insure them always resting the proper distance apart.

The operating-slide D before described is disposed at one side of the longitudinal center of the stock B and is steadied in its movements by aguide-bar V at the other side of the longitudinal center, to which it is'connected by a hand-grip \V,as shown. It serves,

as stated, to transmit reci procatory motion to the breech-bolt C and is provided with a rack portion w, between which and a similar rack portion a; on the feed-bar L is interposed a pinion y, as best showp in Fig. 9. From this it will be seen that the slide D serves to transmit icciprocatory motion to the cartridgefeeding bar as well as' to the breech-bolt; also, that the movements of the breech-bolt and cartridge-feeding bar will be in opposite directions-that is to say, when the breechbolt is moved rearwardly the feed-bar will be moved forwardly and when the breech-boltis moved forwardly the freed-bar will be moved v rearwardly. A

The, operation of my improved magazinegun will be fully understood from the foregoing and need not be repeated in detail. Suffice it to say that with the subchambers II filled with cartridges the gun may be fired very rapidly, it being simply necessary to rciprocate the hand-grasp W after a shot is fired in order to eject the empty shell, place a fresh cartridge in the barrel, and lock the breech-bolt in its closed position. It will also be noticed that the gun may be very expeditiously charged with cartridges, it being simply necessary to raise the shutter G and release and swing the shutters p downwardly and place the cartridges in the subchambers II. With this done the shutters p are raised and fastened and the shutterF closed and fastened, when the gun 1s ready for use.

I have entered -into a specific description of the construction and relative arrangement of the parts of my improved firearm in order to impart a full, clear, and exact understanding of the same. Ido not desire to be understood, however, as confining myself to As uch specific construction and arrangement ot' parte, assuch changes and modifications may be made in practice as fai rlyfall within-the scope of my invention. 1
