MAGAZINE-FIREARM SPECEICATION forming part of Letters Patent No. 676,094, dated J' une 11, 1901 Application filed April 19,1900. Serial No. 13,411. (No model.)

residing at Gwinmine, county of Calaveras,

andEDwIN E. ENDIcoTnresiding at Jackson,

county of Amador, State of California,citizens of the United States, have invented an Improvement in Guns; and we hereby de/clare the following to be a full, clear, and exact description of the same.

Our invention relates to an improvement. in magazine-guns. l

It consists in the combination, with a magazine, of a carrier by which the cartridges are transferred from the magazine to the line of the barrel, and a'longitudinally-slidable breech-bolt by which the cartridges are transf erred to the barrel of a mechanism, and connections whereby the parts are automatically actuated and the gun loaded' and fired continuously until the cartridges are exhausted.

. It also comprises mechanism by which the discharge may be interrupted and the gun fired singly and successively by independent movements; and our invention further comprises details of construction, which will be more fully explained by reference Vto the accompanying'drawngs, in which- Figure 1 is a longitudinal section through the rear part of the gun. Fig. 2 is a horizontalsection of the same 011 line g/ g/ of Fig. 4. Fig. 8 is an exterior view. Fig. 4 is alateral section on line ma: of Fig. 1,. Fig. 5 is a detail showing the adjacent ends of the trigger2 and latch 25. Fig. 6 is an enlarged sectional View of a portion 'of the breech-bolt and frame and the firing-pin and showing the breech-bolt withdrawn. Fig. 7 is a similar View showing thebreech-bolt advanced and locked by the bolts 33. Fig. 8 is a detail showing a portion of the firing-pin, the bolts 33, and a portion of the spring G0,

A is the barrel of the gun, having the magazine 2 located below it and extending to any desired length less than that of the barrel and adapted to contain such number of cartridges as its length will accommodate.

5o breech-bolt and cartridge-carrier.

3 is the stock of the gun, which is hollowed out to contain-the actuating mechanism and connections between this mechanism and the The' breech-bon 4. is 'siid'able 10u gitudinauyin' the line of the barrel. withdrawn to the extent of .its movementearw-ardly, there is a suicient space in front of it to allow a cartridge to be raised from the line of the magazine up to the line of the barrel.

The cartridges in the magazine are pressed backwardly bya spring-actuated follower 1oca'ted in the front end of the magazine. i The carrier 5 is fulcrumed as shown'at 6 and is depressed when the breech-bolt is in its forward position to allow a cartridge from the magazine to pass above the front end of the carrier. tracted, the carrier is tilted about its fulcrumlpoint to raise the front end and bring the Yagain been depressed to receive them. The actuating mechanism consists of a crank or eccentric wheel 7, located in the rear of the stock and turnable therein. This eccentric-wheel has an interior spring-case, within which is contained acoiled spring 8, one end of which is attached tothe shaft 9 and the other so connected with the eccentric that when released its tension acts to revolve the eccentric or crank-disk. The spring is wound up at intervals by means of a crank l0, Xed upon the end ci' the crank-shaft 9 upon the outside of the gun. This crank may be jointed and foldable, so that' when not in use it lies closely against the side of the stock, and the stock may, if desired, be chambered so that the 'from the eccentric 7 either by an eccentricstrap .12; which surrounds and is moved by roo the revolution of the eccentric, or if a cranked l disk be substituted for the eccentric the connecting-rod 11 will be suitably connected therewith by an intermediate pivoted rod connecting with a crank-pin upon the disk, the object in either ease being to convert the revolving motion ot the shaft 9 into a reciprocating motion, which is transmitted to actu- -ate the breech-bolt, carrier, and firin g mechanism'ot the gun.

As here shown, the breech-bolt LL has a lug 13 projecting from the lower surface, and the rear end of the cartridge-carrier is curved upwardly, as shown at 14, so that when the' breech-bolt arrives at nearly the rear-'end of its travel the lug engages the rear end of the carrier, and thus tilts the front end upwardly with its cartridge, as previously described. Vhen the breech-bolt moves forwardly,n the carrier is caused to fall by contact of thelug with the anterior part ofthe curve. A spring 3G prevents the carrier falling while the bolt is advancing. The rearward movement of thebreeeh-bolt 4 is communicated to draw back the hammer 15 by contact with the upper end of the hammer, which is fulcrumed, as at 1G. \Vhen the hammer is thus drawn back, it is engaged by the scar 17, which is pivotcd, as shown, at 1S, and a spring 10, pressing upon Athe lower end oi the scar, causes it to catch with' the notch 2O of the hammer, and vthus retain itin its rearward position.

The mainspring of the gun may be connected in any1 suitable orv desired manner, so

as to .provide the necessary pressure to causev the hammer to fall when released.

Under the conditions hereinafter described it' no stop arrangement is provided for the unwinding of the spring S there will be a continuous reciprocation of the parts connected with the jcranledisl; or eccentric by the rod 11and cartridges vwill be continuously placed in the barrel of the gun and the gun will be discharged in like manner until all the cartridges are exhausted by simply placing the finger upon ihertrigger 2l and holding it back t prevent the pari-ier from being locked.

The sear 17 s moved about its fulcrum- Apoint and disengaged from the hammer by a pin 22, carried hy the reciprocating lconnectingrod 11, so that at each forward movement `of the rod and when the breech-bolt has closed the rear of the gun-barrel this pin striking the sear will disengage it from the hammer and allow the hammer to fall. In lfig. 1 the dotted lines show the position of the parts at the instant of firing. The crank-pin, the center of tlm eccentric?, and the rod 1lr are all in one l..1e, which. position is stronger to resist the reaction caused by the explosion than if -the center of the eccentric and t're rod 11 were to one side of the crank-pin. In such latter case no advantage would be gained' from the resistance of the crank-pin, which has the most strength and is imporf-nr Fn Hmr. nhiect. The trigger 21 is, pivoted, as shown at 23, and the upper end is the spring 24, the' upper end is pulled baclward, anda spring 29, which presses against the lower part of the latch 25, forces the up per endforwardly and causes it to engage with the notch 27. This notch-acts as a lock and prevents the carrier from hein g depressed when the lug 13 comes in contact with it, and thus retains the parts in an inoperative ccndition, because the thrust of the connectingrod -11 against the breech-bolt and'lug 13 being varrested by contact with the locked carrier 5 will prevent any further 4rotation of the eccentric o'I crank mechanism, an d will therefore-prevent reciprocation ot the breech-bolt. Therefore when the gun is locked in this position, the cartridge being in the gun, it is ready for firing. By pulling the trigger 21 ythe upper end will move "forwardly and will tilt the latch 25 until its upper end is disengaged from the' depression 27 and is brought into line with the deeper-notch or depression 28. sure upon the lug 13 will force the forward end of the carrier down and out of its way to advance freely for firing. 'llhe releasing of the hammer and the exploding ot' the cartridge in the gun takes place after the latch 25 has been disengaged from the notch 27, and immediately tfter this action the latch 25 will be brought into line. with the deeper notch 2 S, and this will allow the carrier 5 yto be depressed by the pressure of the connect-- ing-rod ll upon the 'lug 13, and it will then be in position to receive another cartridge, and will lift it, up into line with the barrel as the rod 11 is moved in the opposite direction by the action of thc spring S. At the instant when the lttch 25 has been brought into line with the notch 2S the lower en'd will have ltilted far enough to be disengaged from the to act and force the latch 25 back to the po-` sition where it will engage the notch 27 ol the carrier, and will thus stop the action after another cartridge has been placed in the barrel of the gun.

As shown in Fig. 5, the trigger-latch is formed with a taper toward the front end, and the trigger is mounted loosely upon its pivnt pin. This provides sulicient side movement to enable the trigger io tilt,so as to return along one side of thetrigger-latclr25.

If the gun is to be-loaded and fired continuously, the trigger is onlyT pulled enough to bring the latch 25`int line with the deep notch 28, 'but not far'enough to pass the lower end of the latch and release it. The latch being thus heldin this position, the pin 22 on the rod 11 will strike the Sear 17 at cach .revolu- Vv'vhen 'in this line, the continued pres- ,ICO

tion of the crank or eccentric and will disengage from and allow the hammer to fall. The other movements of reciprocating the breechbolt and .tilting the carrier are carried on continuously until the cartridges have been exhansted from the magazine.

The front end of the breech-bolt is provided with an extractor 3l,which engages the groove vror ilange of the shell,'and upon-the opposite side is a slidable bolt 32, which is pressed forward when the breech-bolt is retracted and after the shell is clear of the gun-barrel by striking a stop, or by other suitable means, so

as to give the cartridgea turn about the hook 3l, which holds the opposite edge, and thus:

eject it;

In the construction adopted forthis gun it is desirable to have the top of the breechbolt and moving parts covered and inclosed by acasing or frame B, and we have designed to leave a side open opposite the chamber, so that the cartridge-shell can be ejected to'one side of the gun; but whatever the direction in which the cartridge is to be ejected the hook 3l and the ejector 32 will be so disposed .with relation to the opening as to throw the In order to lock t-he or latch d, corresponding with the bolts orlatches 33, said bolt or latch d being substantially at right angles with bolts or latches 33 and adapted to engage an opening 37 in the top of the frame B. W hen the breech-boltis retracted, the latching-bolts 33 are resting against the conical part of` the ring-pin 34 and against the wall of the frame B, as shown in Fig. 6. When the 'breech-bolt 4 is moved forward at the proper time, the bolts 33 will arrive opposite the openings 37, and are then -pushed into these openings by the pressure caused by the inclined form ofthe cone-shaped end of the ring-pin, as shown in 7. "While the pressure of the tiring-pin against the bolts 33 may be the same while they are within the frame B, it will be manifest that they could not be pushed outwardly until they arrive opposite the openings 37, and when they are push-ed into said openings they lock the breech-bolt to the frame, as shown in. Fig. 7. Then retracting the breech-bolt, the bolts 33 are withdrawn from the slots 37 by the action of springs 70, thus freeing the frame from the breech-bolt, and the said bolts 33 are then drawn back along the inside wall of the frame with the breech-bolt, as shown in- Figs. 2 and 6. When in theposition shown in Fig. 7, the firing-pin hasbeen forced forward by the action of the hammer and against the tension of the springGU, having first pushed the bolts 33 into the openings 37, thus freeing the pin and allowing it to move forward. Immediately after the explosion the spring forces the pin back again, presenting the conical portion of said pin to the bolts 33, and this allows the bolts 33 to be` again retracted by 'the springs 70 from the slots 37, so that the outer ends of the bolts are flush with the outside of the breech-bolt, allowing the latter to be withdrawn again, as shown in Figs. 2 and 6. The firing-pin is of two diameters, with a coneshaped connecting-shoulder, and this shoulder being forced between the inner ends of the latches when the hammer strikes the firing-pin forces the latches outward into engagement with the notches or stops inthe casing.

Then the breech-bolt is retracted, the latches 33 rest on t-he cone-shaped part of the firing-pin, their outer ends sliding against theinside'walls of the casing B. vWhen the breech-bolt is moved forward to its farthest limit, .the latches having been carried along will be brought into line with the openings 37 in the casin g, so that when the pin is struck the latches will be forced into this opening by the advance of thecone upon which they rest simultaneously with its movement to explode the cartridge. After the firing the cone is forced back by the spring and allows the'. latches to drop down upon it and'out of the openings 37, ready to be withdrawn again with the breech-bolt, this movement of the latches being facilitated by some well-known ,Ico

form of light spring connection-such, for inf stance, as shown in Fig. 7. One portion of the right side of the butt may be hinged to the other, as at 38, to gain easy access to the interior mechanism.
