EJECTINGMECHANISM FOR BREAKDowN GUNS.

SPECIFICATION forming part of Letters Patent No. 554,002, dated February 4, 1896.

Appiiaunfned september 7,1895. serian. 561,822. No model.)

A Myinvention relates toshell-ej ectin g mechanism for breakdown guns.

The object of my invention is to provide animproved ejectingv mechanism of very simple construction an-d operation, and my invention' consists in certain novel features ofconstruction and operation of my ej ecting mechanism, as will be hereinafter fullydescribed, and the nat-ure thereof indicated by the claim.

Referring tothe drawings, Figure 1 is a side vie-w of a portion of a breakdown gun embodyinginy improvements. Fig. 2 is a side view of the inner end of the barrel detached and the barrel-lug, showing'the ejector in its inward position. Fig-3 is a central longitudinal section through the parts shown in Fig. 2. Fig. 4 is a cross-section taken on line 4 4, Fig. 3, looking in the direction of the arrow, same iigure. Fig. 5 corresponds to Fig.Y 2, but shows the ejector in its outward position; and Figr is a central longitudinal section through the parts shownin Fig. 5.

In the accompanying drawings: `1 -isthe frame of a breakdown gun of ordinary construction, and 2 is thebarrel portion, jointed i to the front part of theframe by the pin Sin the usual way. The barrel 2 is provided with a barrel-lug 4, which in thisdinstance contains thevej ecting-mechanism. The ej ecting mechl anism consists of the ejector-rod jprovidedV .SVO

Vat its outer endwith'the ejector 6, of the rdinary construction. The rod 5 is adapted to have a longitudinal motion in a hole or re- Y cess 7' in the lower `part of the barrel. A spiral spring 7 isllo'cated within the inner end of said hole 7. and is adapted to bearagainst the Y 4inner end of said rod` 5 to forcethe saineout,

and operate the ejector to eject the shell'on the breaking down of the gun. vThe ej ector-rod 5 has a'notch or depression 5 in the lower part thereof, through which extends a pinB, secured in the barrel-lug 4.

Said pin 8 acts`to limit the outward motion' of the ejector-rod, as shown in Fig. G. 'The e jector-rod 5 also has a wedge-shaped notch or depression'l in the lower part thereof, intowhich is adapted to extend the inner beveled end of a movable pin 9,which extends in a vertical hole 10 in the barrel-lug 4, and is adapted to have a longitudinal motion therein. A pin 12 extends in a notch 9 in said pin 9, and is secured in the barrel-lug 4, as shown in Fig. 4, and acts to limit the longitudinal motion of said pin 9, as shown in Figs. 3 and 6.

The pin 9 has a lug or projection 9" extending out from one side thereof at its outer end, :as shown in Fig. 4. A flat spring 13 is sethe barrel projection or lug 4, as. shown in Fig. 4, and whichV engages the lug 9" on the pin 9 (the end of said lug being preferably made beveled, as shown inV Figs. 2 and 5) when the barrel is broken down.

The inner end of the screw 16, engaging the projectiontl" on the pin 9as the barrel is broken down, moves out said pin against ,thev

The barrel-lug 4 is proj mechanism, extends into the depression 15 inlaction of the spring 13, and disengages the e inner end thereof from the notch 5'/ in the ejector-'rod 5, allowing the spring 7`to act to force outA said ejector-rod 5, and the ejector`6, vas shown in Fig. 6, to eject the shell.- After theshell hasbeen ejected the return of the barrel to be locked to theframe moves lthe projection 9/ away from the inner end ofthe screw 16, and allows the spring 13 .to act to push up the pin 9 and cause the inner end thereof to engagethe notch 5" in the ejectorrod as said rod is forced back to its inward `position by the Y,closing of thebarrel and hold saidrod, as shown in Fig. 3.

'IOO

In case it is desired not to have the ej ecting mechanism operate, lthe screw 16 is turned out, so that the inner end thereof will not en gage with the projection 9" on the pin 9, and said pin will remain stationary and hold the ejector-rod in its inward position when the gun is broken.

The advantages of my construction of the ejecting` mechanism will be readily appreciated by those skilled in the art. It is of very simple construction and there are only a few parts, and the pin 9, which holds the ejector-rod in its inward position, is positively operated on the breaking down of the gun to release the ejector-rod and allow the same to operate to eject the shell by the screw 1G in the frame 1. The pin 9 is returned to its inward position to hold the ejector-rod by the action of the spring 13.

AIt will be understood that the details of construction of some of the parts of my ejecting mechanism may be varied somewhat, if desired.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

In the ejecting mechanism of breakdown guns, 'the combination with a spring-actuated ejector-rod, provided with a notch, and a movable pin which engages said notch, and a spring which holds said pin in said notch, of a screw or pin which extends transversely in one side of the frame at the front portion thereof, and engages said pin or a projection thereon upon the breaking down of the gun, to canse the same to be disengaged from the ejector-rod, and allow said rod to operate, substantially as set forth.
