MAGAZINE-GUN.

SPECIFICATION forming part of Letters Patent No. 334,535, dated January 19, 1886. Application filed November 15, 1884. Serial No. 147,994. (No model.)

To all whom it may concern:

Be it known that I, JOHN M. MAELIN, of New Haven, in the county of New Haven and State of Connecticut, have invented a new and useful Improvement in Magazine Guns, of which the following is a specification.

My invention relates to magazine fire-arms; and it consists in certain improvements in the parts thereof which transfer the cartridge from the magazine to the barrel, substantially as hereinafter described and claimed.

In the drawings, Figure 1 represents the breech and rear part of the barrel of a magazinegun, partly in section. Fig. 2representsa portion of Fig. 1, including the point of junction of the carrier and magazine, with the carrier in section. Fig. 3 is a side viewof the carrier, showing one side of it. Fig. 4 is. a View of the same on the opposite side. Fig. 5.is a top view of the same. Fig. 6 is a front end view of the same. Fig. 7 is a rear end view of the same. Fig. 8 is a view of the same in vertical longitudinal section. Fig. 9 is a separate view of a stop or spring to be attached to the carrier.

A is the breech of the gun.

B is the barrel.

M is the magazine-tube.

F is a frame-work of metal connecting the barrel and magazine, and constructed to receive and carry the mechanism of the carrier, breech-bolt, and lock mechanism.

Gis the carrier, which slides vertically up and down in a slot or mortise extending vertically through the frame F, as shown, and immediately in rear of the magazine and barrel. The magazine-tube M is intended to receive and hold another removable tube constituting the magazine proper, and having a bore of the same diameter as the passage m. The magazine-tube M may, however, be used directly for the magazine by reducing its internal bore to the size of the passage m. The cartridges are fed through this passage and into the carrier, in the usual manner, by the pressure of a spring upon the cartridge nearest the left-hand end of the magazine in the position of Fig. 1.

The carrier C is raised and lowered by the lever e, which is moved up and down by the lever N, the latter being pivoted at n, and at its lower end forming the trigger-guard of the arm,

while its upper end projects into the slot nin the breechblock n, and withdraws it at the same time that the carrier C is raised. The lever e projects into a slot7 c, in the carrier, and has a lug or projection on the upper or right hand side of lever N, and extending across the path of the latter, and another on the lower side of lever N in like position. As the lever N -is swung up or down, it strikes against these lugs and raises and lowers lever e, the latter being pivoted at s. The carrier C hasa chamber, c2, bored longitudinally through it, to receive the cartridge in the ordinary manner, and a slot, o3, reaches from the upper side of the carrier downward to this chamber'. When the carrier is lowered, as described, the chamber"cL comes opposite the passage m into the magazine, and when it is raised thev chamber comes opposite the bore of the barrel. When opposite the magazine, the pressure of thespring in it against the series of cartridges at one end forces the cartridge at the other end into this chamber cl of the carrier, and when opposite the bore of the barrel the forward end of the breech-block n3, which is shaped properly for the purpose, passes through this chamber' c2 and forces the can tridge into the breech of the barrel. The carrier then descends to receive the next cartridge from the magazine, the slot c3 allowing the part n3 of the breech-block to pass through it and this movement to occur. It will be readily understood that the proportions of the 1evers e and N, and position and proportions of the slots in the breech-block and carrier in which they work, are such as to produce these movements of the breech-block and carrier, as described. Heretofore it has been customary to provide a fixed stop in the chamber c2 of the carrier far enough back from the open end of it, which abuts against the magazine-passage m, t0 just allow a cartridge to be received in it and have the end of the cartridge just come even with this abutting end of the chamber. This was necessary, because if the end of the received cartridge projected beyond the chamber it would be jammed against the frame as the carrier was raised up, while if it did not come out as far as this abutting end of the chamber c2 the next cartridge in the maga- IOO zine would partly enter the chamber c2 and prevent its being raised to the barrel. As the cartridges vary slightly in length, however, even the method of placing the stop in the carrier does not prevent the jamming of it in one way or the other to some extent in practical use. To avoid this difficulty, I form the carrier with a slot, c4, in the end face of vit, which runs against the barrel and magazine, this slot being narrower than the diameter of the cartridge-head transversely, but slightly I. broader than the cylindrical part of the cartridge. I then undercut this slot laterally, so as to leave lips c5 c on each side at its outer edge, the under-cnt being of sufficient transverse breadth to allow a cartridge-head to slip easily through up and down behind the lips.

'I next cut off or terminate the lips c5 c5 at their bottom ends, so as to allow a cartridge-head to just pass by them and rest in the bottom of slot c4 at the time when the carrier is raised, so as to bring the chamber c`l opposite the bore of the barrel.

Y Yinthe slot and projects in line with one of the lips c5, before described. This right-angled y end of the spring, that projects across the front end. O'f chamber` c, has its outer face flat and substantially parallel and coinciding with the front face end of the carrier; but the inner face of this projecting end of the spring o in the chamber c2 is beveled ofi', as shown. This spring will therefore prevent a cartridge from being shoved head end foremost into chamber c from the front end face of the carrier; but when a cartridge already in the chamber is forced ball end foremost out of its front end the bevel on the inside of the end of the spring o will cause it to yield and allow the cartridge to pass out.

The operation of thispart of the device isas follows: When the carrier C israised, with its chamber c2 opposite the bore of the barrel, the lips c5 c5 will be carried upward far enough to allow the head of a cartridge in the magazine to pass by them and rest against the bottom of slot c. As the carrier is lowered to bring chamber 'c2 opposite the magazine, the head ofthe cartridge will pass behind lips o5 c and `the projecting end of spring o until, when the chamber c2 comes opposite the magazine, this cartridge will be pressed into the chamber in the usual manner. When the head of the following cartridge, which is pressing upon the first, reaches the bent end of t-he spring o, its progress will be arrested, and it cannot enter the chamber c2 until it has first passed behind the lips o5 c5, as before described, after the carrier is raised to bring the rst cartridge in line with the barrel. The second or following cartridge can never jam the carrier owing to the first or preceding one being too short, nor can the first or preceding cartridge jam the carriel` because too long, because I place my stop in the chamber c2 far enough back from the front end to allow the longest cartridge to pass entirely within the chamber. I am enabled to do this, since I no longer depend on this stop to arrest the second or following cartridge at the right place in the magazine.

In order to present a smooth and even passage-way for the cartridges to slide over into the carrier, as well as to insure the head of the shell passingsmoothly behind the lips c5 c5 as the carrier descends, I attach a tongue,

u, to the rear side of the frame-work, below and behind the magazinetube M, as shown in Fig. l in dotted lines and in Fig. 2. This tongue lits and fills theslot c4 in the carrier,so

as to slide freely therein, and it has a rearwardly-projecting lip on its lower end, that fits into a corresponding cavity, u,in the carrier C when the latter has reached its lowest point of descent,and thus arrests its motion at exactly the right point.

On one side ofthe carrier G,I attach a spring,

o, by a screw, of, and form the free end of the spring in two branches, as shown in Fig. 3.' Underneath each of these branches a small transverse hole, o2, is bored through the wall of the carrier intothe chamber czfwllt-pliln-Y-V Y ger, v3, is made long enough to reach into chamber with a head like a common screw,

the groove across the face of the head beingwide enough to receive either member of the bifurcated end of spring fv. By inserting the plunger o into one of the holes o2 it can be turned so as to have a member of this end of spring o, which also turns on screw o', drop into the groove'across the head, and this will hold it securely in place, and its inner end,

projecting into chamber c2, thus forms a stop for the cartridge in the chamber.

By the use of any sharp-pointed tool the spring o can be lifted and the plunger o8 transferred to the hole under the other member of the bifurcated end of spring t very easily and quickly, to adapt it to a different length of cartridge. v

IOO

IIO

It is obvious that the spring o and groove K c* could be made eective to operate in the manner before described, even if the lipsvc6 c were dispensed with and the` groove c* madeof the same ,width as at the bottom its entire depth, because only one cartridge could'enter the chamber c2 at a time; but I prefer to use the lips, as in case the carrier was accidentally enough from thev delivery end of chamber c,

the cartridge in the chamber could, however,y

rfi

yield enough to pass by the head of the following one, even in the ease last supposed.

I do not in this application claim any improvement herein shown in the breech-bolt, lock, firing, or extracting mechanism, as I propose to make such -improvement the subject of another application for Letters Patent which I propose to make therefor; neither do I claim the lips c5 c5 in any other combination with the carrier-block than hereinafter claimed, as there are other combinations of them,with the several parts somewhat diierently arranged, on which I am about to make application for Letters Patent.

Vhat I claim as new and of my invention 1. In combination with the cartridge-car rier C, provided with the cartridge-chamber c2, spring-stop o, placed at the delivery end 2o thereof, and with slot c, suitable mechanism for raising and lowering the said carrier, and
