EJECTOR MECHANISM For: FIREARMS.

SPEGIFIIOATION forming part of Letters Patent No. 715,903, dated December 16, 1902.

Application filed April 25, 1901. Serial No. 57,364. (lilo model-l I .The present invention relates to extractor and ejector mechanism'for guns of the breakdown type, and is shownas embodied in a single-barreled shotgun. The object of the invention is to simplify I5 the ejector mechanism, so as to obtain a device which will operate satisfactorily withoutmaterially increasing the expense of construction.

In accordance with the invention the extractor, which cooperates with theflange of the shell in the usual way, is mounted in a suitable guide in the barrel-lug'and is provided with aspring, the tendencyof which is to move the extractor in such a direction as to force the shell out of the chamber. The said extractor is normally held in place against the stress of the said spring by means of a catch which is arranged to be operated upon by a catch-actuator'or tripping device in 20 response to the movement of the barrel with relation to the frame when the gun is. broken down or opened. Both the catch and the tripping device are movably mounted in a recess in the barrel-lug below the extractor-guidei In accordance with the invention the frame is provided-with an undercut recess for the barrel-1ug,.the shoulders at the top of the said recess cooperating with the tripping device to release the ejector when the barrelhas- 40 been tipped down far enough to permit the shell to clear the'breech-block.

The tripping device is shown as pivotally mounted, and the pivot-pin is arranged to ex tend laterally beyond the barrel-lug and constitutes a stop to prevent the barrel from being tipped beyond a certain point, the engaging portion of said tripping device being so related to the said pivot that it will be acted upon just before the said pivot is stopped, thus releasing the ejector. vThis stop prevents any further movement of the tripping device, so thatthe movement of the catch is limited, and the said catch may be arranged to cooperate with a second engaging portion of theejector to limit the movement thereof-.55, and hold the same against the stress of the spring after the ejector action. e

Figure 1 is a longitudinal section of a device embodying the-invention, the gun being.

shown as closed Fig. 2. a similar view showon;

ing a gun broken down or open; Fig. 3, a transverse section showing the gun closed; Fig. 4, a modification, and Fig. 5 a perspective view of the tripping device alone.

The extractorrod a, which is also utilized as an ejector, is mounted in-a guide-bore?) in the barrel-lug B and is acted upon by a suitable spring b herein shown as a spiral. spring, interposed between the end of the ex- I tractor-rod and the endof the guide-passage. 7c

The said.ex tractor-rod is held-against the stress of said spring by means of a catch c'in such a position that the shell-engaging portion a will not act to any material extent upon the shell, the spring I) thus being kept under tension, and the said catch cis nibv- "f ably mounted in thebarrel-lug and normally stands in the path of a shoulder a formed on the under-side of the extractor-rod a. As indicated in Figs. 1 and 2, the said catchfc '80 consists of a vertically movable plunger mounted in a guide here or opening B in the barrel-lug and capable of being moved toward and from the extractor, so as to engage or disengage the shoulder a The said catch is arranged to be acted upon by a tripping device d, which is pivotally supported in the barrel-lug, the pivotal support being shown as afl'forded by a transverse pin d, which extends completely through the barrel-lug and .jgo

projects beyond the same atone or both.

sides. In the construction shown in Figs. 1 and 2 the said tripping device has a projection 01 which epters a suitable recess'in the plunger c, and the tripping device (1 is also acted upon by means of a spring (1 the tendency of which is to rock the tripping device upon its pivot in such a direction as to force the catch 0 toward the extractor-rod a. .With

the parts in normal position, therefore, the .to full action of the spring I) upon'the extrac tor-rod is prevented by the said catch 0, which is in the path of the shoulder a w i To get the proper'e3ector action, it is nee-- This may be accomplished, as herein shown,

'suificient strength to force a shell out if it essary that'the parts should remain substantially in this condition until the gun has been. nearly opened, the extractorwod then being released, so that the spring gives it a sudden impulse, which results in kicking the shell clear of the chamber. To perform this operation, the tripping device d is shown as provided with tripping projections (Z which extend laterally beyond the sides of the barrellug, and the frame A of the gun is provided with an undercut recess A-, the projecting shoulders A of which overlie the tripping projections (Z so to engage the same when the gun is broken down and the lug moved upward in the recess.

The pivotal support 61* is so arranged with relation to the tripping projections d as to engage the shoulders A as soon as the projections have been moved far enough to Withdraw the catch c from the shoulder (L in order that the said catch may constitute a stop to limit the outward movement of the ejector+that is, to prevent the same'from flying clear of the barrelthe said ejector is provided with a second shoulder a in the path of which the catch 0 stands when the gun has been opened as far as the stops (1 Will allow.

It is advantageous that the shell should be loosened in the chamber prior to the action of the spring 19 which might otherwise laclr were stuck in the chamber to any extent.

The catch 0 normally stands far enough in front of the shoulder a to admit of such slight movement, the ejector member being held, of course, when the gun is closed by engagement with the breech-block.

The catch may obviously be supported in the barrel-lug in any suitable Way,'a modification being shown in Fig. 4 in which the catch cis pivotally supported upon a pin 0 which extends transversely through the lug, the action being the same as in the construction already described.

I claim 1. Extractor and ejector mechanism comprising an extractor longitudinally movable in the barrei-lug and provided with a spring;

. a catch movably supported in the barrel-lug below said extractor and adapted to hold the same against the stress of its spring; a tripping device independent of but cooperating with said catch, said tripping device also beingmovably supported in the barrel-lug; and an undercut recess in the frame, the upper surfaces or shoulders of which are adapted to codperate with a projecting portion of the said tripping device when the barrel is tipped, as set forth.

2. The combination with the frame provided with an undercut recess for the barreldug; of an ejector mounted in the barrel-lugand provided with a spring; a catch for said ejector also mounted in the barrel-lug; atripping de vice for said catch mounted on a transverse pivot'pin in said lug, the ends of the said pin projecting beyond the sides of the said lug to cooperate with the upper or overlying surface of the undercut recess in the frame and afford a stop for the barrel; and a projection of said tripping device also projecting beyond the side of the barrel-lug to engage the upper surface of said recess before it is engaged by the pivot-pin, substantially as described.

3. The combination with the ejector pro vided with a spring; of a catch for said ejector consisting of a plunger mounted in a suitable bore in the barrel-lug and cooperating with a shoulder on the ejector; a tripping device pivotally sn pported in said barrel-lug and cooperating With said catch; and an undercut recess in the frame, the upper or overlying surface of which cooperates with the tripping device to release the ejector, substantially as described. i

.4. The combination with the ejector provided with a spring; or" a catch forsaid ejector to hold the same in position against the stress of said spring; stripping device forsaid catch mounted in the barreldug and having a projection underlying the upper surface or overlying portion of an undercut recess in the frame; and a portion of said tripping device to engage and positively actuate said ejector prior to the tripping of the catch, substantially as described.

In testimony. whereof I have signed my name to this specification in the presence of two subscribing witnesses.
