SHELL-EJECTOR FOR GUNS.

Specification of Letters Patent.

ltatented May 2, 1911.

To 1f/7. whom it may concern:

Be it known that I, Fnnnnaicn T. RUS- senn. a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Shell-'Ejectors for Guns, of which the following is a specification. I

This invention relates to certain improvements in shell ejecting mechanism for breech loading break down guns, particularly of the double barreled type.

The object of the invention is to so construct the mechanism that the ejector will eject both empty shells when both barrels have been tired or in the event of only one barrel being tired, then only one empty shell of that particular barrel will. be ejected.

The invention also relates to certain detailed improvements in the ejecting mechanism which will be described hereafter. reference being had to the accompanying drawings, in which Figure 1, is a longitudinal sectional view of a double barrel breech loading gun on the line 1--1 Fig. el., showing the barrel in outside view; Fig. 2, is a view similar to Fig. 1, illustrating the gun in the broken position; F 3, is a view similar to Fig. l, showing the gun after the barrel has been returned to its normal position and the hammer cocked; Fig. 4, is a sectional plan view on the line -flf et, Fig. 5l; Fig. 5, is a detached perspective view of the plunger; Fig. G, is a detached perspective view of the trip; Figs. 7 and 8, are diagram views illustrating the movement of the trip plate; Fig. 9, is a modification of the trip mechanism; Figs. 10 and 11. are views of another modification ot the trip mechanism; Fig. 12. is a detached perspective view of the details of the trip mechanism shown in Fig. 10, and Fig. 13, is a view showing the retracting cam face on the scar.

is a portion of the frame of the gun. B is the barrel hinged to the front part of the frame by a pivot pin C. Depending from the barrel B is the cooking lug which engages one arm (l of the firing hammer D when the barrel is moved to the position illustrated in Fig. 2, so as to recock the tiring hammer. This firing hammer is pivoted at Z2 and is retained in the cocked position by the scar D2 which engages a retaining notch (Z3 n the usual manner.

E is the ejector having a head c and F/ is the ejector hammer held in its retracted position by a scar F against the pressure of a spring e', the spring being confined between the head c2 of the ejector hammer and a lug 7) on the .foreend iron carried by the barrels. This head has a notch c3 which is engaged by an arm f of a pivoted scar F when the ejector hammer is pushed forward as illustrated in Fig. 1. The forward end of the ejector E bears against the head c2 of the ejector hammer and the ejector is so proportioned that its head c will contact with the breech face a and on closing the barrels will be forced forward, causing the ejector to move toward the ejector hammer and to force it forward against the pressure of its spring to the position illustrated in Fig. 1.

It .will be understood that this particular gun is what is known as a double barreled breech loading gun and the mechanism above described is duplicated; one set of mechanism being for the purpose of discharging the red shell from one barrel of the gun and the other from the other barrel of the gun. The mechanism which I will new proceed to describe is also duplicated. I 1s a plunger having a head z' at the end m which is a conical recess to receive the end of the toggle D pivoted at Z2 to the firing hammer I). Mounted between the head z' and the shoulder on the forward end of the frame A is a spring- I tending to force the plunger rearwardly. The forward movement of the plunger is given to it by the cocking of the ring hammer. In the forward end of the plunger I is a slot z, as clearly illustrated in Fig. 5, and mounted in this slot is the trip plate N, Fig. G. This trip plate has laterally extending lugs n n, which travel in slots c in the frame A. The rearward movement of the plate is limited by the lugs coming in contact with the shoulders a2 on the frame, as illustrated in Figs. 4 and 8, which show it in the inoperative position. The slot e" in the plunger I is so proportioned to the thickness of the trip plate that the trip plate must be forced into the slot and is held therein by spring tension or friction, and while this friction is sutlicient to carry the trip plate forward when the plunger is moved forward, as illustrated in Fig. 7, which shows it in the operat tive position, it will not prevent the real."-

ward movement of the plunger due to the pressure of its spring when the trip plate is stopped on its rearward movement, by coming in contact with the shoulders a2.

The sear F is pivoted at f2 and has a hooked arm f in the present instance which extends through the foreend iron B and close to the curved surface of the frame A. A spring f3 tends to hold the sear in the position illustrated in Fig. l, in contact with the shoulder c3 on the head of the ejector hammer E.

n2 is a cam surface on the end of the foreend iron for forcing the trip plate N back into the inoperative position after it has been extended and as the barrel is returned to the position illustrated in Fig. 3. The en d n of the trip plate is projected to operative position on the forward movement of the plunger I into the path of the arm f of the sear F as the barrel is turned on the pivot C to the position illustrated in Fig. 2, forcing the sear to release the ejector hammer, which will be moved by its spring and its head will contact with the end of the ejector causing it to eject a fired shell from one of the gun barrels. hen the gun barrel is returned to the position illustrated in Fig. 8, the end a of the trip is forced to the inoperative position into the slot of the plunger by contactwith the cam surface n2. This brings the lugs n of the trip plate against the shoulders o2, preventing its further rearward movement. When the plunger I is released it is moved rearwardly by its spring when the firing hammer strikes the blow to discharge the cartridge, as in Fig. 1. This movement projects the trip plate beyond the end of the plunger I as the plate is held by the shoulders a2, so that when the plunger is forced forward on the cooking of the hammer the trip is carried with it and the end n of the trip extends into the path of the arm f of the sear F in the operative position, causing the sear to release the ejector hammer, as before described. This mechanism is duplicated, and, as above mentioned, one set of mechanism is entirely independent of the other so that when one barrel is discharged then the shell of that barrel is the only one ejected, whereas, when both barrels are discharged, then both shells are ejected, or if neither is fired, then neither one is ejected. By this arrangement one barrel can be discharged and reloaded and the gun broken as many times as desired without affecting the cartridge or the shell in the other barrel.

In Fig. 9, I have shown a modification of my invention in which the plunger I2 is slotted at the outer end and mounted in the slot is a pivoted trip plate N in the form. of a pawl having a tooth, which is arranged to engage one arm of the sear F. This pawl trip plate is held by friction in the slot of the plunger' I2 so that when the plunger is retracted by the action of its spring, the pawl will strike a portion of the frame A and will be forced to turn on its pivot and as the plunger is moved forward again the pawl trip plate will be frictionally held in the slot. of the plunger and its tooth will project when in the operative position into the path of the arm of the sear F and will engage the sear when the gun is broken. On the return of the barrel to its closed position the projection on the cam surface of the foreend iron will push the pawl trip plate back out of its path to the inoperative position.

In Figs. 10 and ll, I have shown a still further modification of the invention in which the plunger I3 is slotted at its outer end forming forks and instead of being contracted the forks are bent away from each other and are adapted to a cavity in the sliding trip piece N2; the forks binding upon the walls of this cavity holding the trip piece in frictional contact with the plunger. The trip piece has a projection a3 which engages the sear F. The outward movement of the trip piece N2 is limited by the head of a screw 7c, illustrated in Fig. ll; the trip piece being notched as illustrated in Fig. 12, to receive this head. The rear end of the trip piece strikes the shoulder at the base of the cavity in which it is mounted when the plunger is forced back by its spring and as the trip piece is free to slide in its cavity, it will be carried forward by the plunger when said plunger moves forward again due to the frictional contact of the same, accomplishing` the same purpose as that of the trip plate illustrated in Fig. l.

In Fig. 13, I have `shown the cam face a3 on the scar F2, the cam face acts upon the trip N and forces it back into the inoperative position when the barrel is returned to its normal position.

In the claims, I have referred to the ejector, meaning thereby an ejector in its broad sense, including the ejector proper and the ejector hammer and it will be understood that different types of ejectors and different forms of sears for retaining the ejector in the retracted or normal position may be used without departing from the essential features of the invention. Furthermore, the trip may be frictionally confined to the plunger in many different ways and in the drawings I have shown the simplest forms only; the essential feature of the invention being the trip so connected to the plunger that it will be carried forward with the plunger to the operative position so that it may release the ejector when the gun is broken and allow it to be positively retracted when the gun is returned to its normal position. When the plunger is moved back by its spring the trip plate will be retained by un -rws v.: ai tira,

lili/'emililoading,

shoulders, allowing the plunger to have a further movement, thus re-setting the trip plate and allowing its end to project beyond, the plunger so that when it is carried forward again by the plunger its projecting end will be in position to actuate the sear or other device to release the ejector.

Thile l have illustrated my invention in connection with a double barrel gun, it will be understood that the invention may be used on a single barrel gun without departing from my invention.
