This invention pertains to a firearm of the breakdown type, and more particularly to automatic ejector and cooking mechanism operated by relative interpivotal movement of the gun barrel and stock.

rEhe instant invention is applicable to firearms oi either single or double barrel style, wherein the barrel is hinged for tilting motion to expose the breech for insertion and ejection of the shells. There is contemplated a construction wherein the barrel is detachably engaged with a forearm member medially pivoted to the frame forwardly of the iire control mechanism with the rearward portion thereo extending into overlapping relation with the forward portion of the frame, upon which is carried means for eifecting both the ejection of a discharged shell and the actuation of the cooking device during the opening motion oi the gun.

The object of the invention is to improve the construction as well as the means and mode of operation. of firearms, whereby they may not only he or simple construction and capable of being economically manufactured, but will be more emcient in use, automatic in operation of ejecting the spent shells and cooking the hammer preparm tory to the next nring operation, uniform in its action, have relatively few operating parts, and be unlikely to get out oi order.

A further object of the invention is to provide a taire-down nrearm which may be assembled and disassembled while the gun is in either its cocked or discharged condition.

A further object of the invention is to provide an easy closing gun having automatic ejector and cooking mechanism operative during the opening movement thereof, and aording minimum resistance to its closing motion.

A further object of the invention is to provide a forearm construction having interlocking engagement with the gun frame which relieves the hinge connection of the barrel and ...une of strain makes the gun more rigid and assures proper alignment of the barrel and 'slr whilethe gun is in operating condition, and which positively 1limits its opening movement.

A further object of the invention is to effect ejection of the spent shell or shells by an initial opening motion of the gun and the cooking action motion, thus relieving the closing motion of the gun of all resistance.

A further object of the Vinvention is to provide compact ejector operating and cooking means which may be readily incorporated in existing hy a further continuing opening guns without disturbance of the fire control mechanism or gun operative means.

A further object of the invention is to provide a iirearm of the character` mentioned, possessing the advantageous structural features and inherent meritorious characteristics and mode of operation herein set forth.

With the above primary and other incidental objects in View as will more fully appear in the specification, the invention intended to be protested by Letters Patent consists of the features of construction, the parts and combinations thereof, and the mode of operation, or their equivalents, as hereinafter described or illustrated in the accompanying drawings.

Fig. 3 is a bottom plan view of a portion of the gun frame and the forearm.,

Fig. 4 is a perspective View of the forearm member disconnected from the gun.

Like `parts are indicated by similar characters of reference throughout the several views.

The gun shown herein is of conventional form and general construction to which the present inventive features forming the subject matter hereof have been added. The gun comprises the stools l, including the frame 2, to which is pivoted att a forearm member 4, to which is detachably engaged the barrel '5.

As shown in Figs. 3 and 5, the forward portion of the frame 2 is longitudinally slotted, and the .forearm l is provided with a rearwardly extending arm 6 which projects within the slotted frame 2 beyond the pivotal connection 3. The arm 6 interloclis with the frame 2 to resist side play and stiiens the gun and relieves the pivotal connection t o-f stress and strain. At the limit of the range of the opening motion the arm B affords a positive stop to limit the range of opening motion of the gun. The trunnion 'l forming part of the hinge connection of the forearm and frame is integral with the frame 2 and transversely bridges the end of the slot therein. The forward half of the trunnion 1 is substantially semi-cylindrical, of larger diameter, and fits within a semi-circular groove or socket Ii in the forearm member. The rearward half of the trunnion 1 is of semi-cylindrical form of lesser diameter, and is engaged in a corresponding semi-circular notch 9 in the forward face of a lug l!) projecting from the under side of the barrel 5, with which it is I'lxedly attached, into the slot of the frame 2 when the gun is assembled.

For ejector purposes there is provided a movable segment II, or two such segments in the event the gun is of double barrel style. The ejector segment II forms a part of the breach of the barrel to receive the shell, which normally abuts against the segment I I. The latter is connected to a reciprocatory stern I2 slidingly mounted in a bore in the bottom of the gun barrel 5 beneath the bore thereof. Upon retraction of the stem I2 and with it the ejector segment II, the shell is withdrawn from the barrel I. The ejector means as thus far described is conventional and is such as commonly found in commerical firearms at the present time. Pivoted Within a recess or mortise within the rearward portion of the frame 2 upon a pivotal stud I3 is a hammer or impact member I e subject to the reaction of a main spring I5 also enclosed in the frame 2. The hammer Iii is held retracted or cocked against the tension of the main spring I5 by an L shaped sear I6 which is pivoted within the frame 2 upon the trunnion stud i1. The sear IB includes arrearwardly extending arm i8 which overlies a conventional form of trigger I9 pivoted at 2B and enclosed by a trigger guard 2i. The sear I6 is provided adjacent its elbow with a detent shoulder 22 which is pressed into engagement with a corresponding detent shoulder 23 upon the hammer I4, by a spring plunger 24 seated in a hole 25 in the forward portion of the stock and exerting pressure against the upstanding arm of the sear I6. Upstanding upon the inner f ace of the rearwardly extending arm E of the forearm is a notched lug 25, the upper portion of which is slotted and receives therein an arcuate oscillatory lever 21, which is medially pivoted at 28 in the upper portion of the lug. The upwardly extending arm 21a of the lever 21 extends into the path of the reciprocatory ejector stem I2,

and by its oscillation pushes the stem I2 rearwardly to eject the shell. The opposite end 21h of the lever 21 normally extends rearwardly of the lug 26 coincident with the medial notch 26a of the lug. and upon oscillation is retracted with a continuing portion of the slot within the lower portion of the lug beneath the shoulder formed therein by the notch 26a.

Disposed along side the hammer Ill and pivoted on the same stud I3 for oscillation in a plane parallel with that of the hammer, is a cooking lever 29, the rear end of which extends into the path of a laterally extending lug 3D on the side of the hammer Id. The forward end of the cocking lever 29 normally overlies the top of the lug 26 intermediate the lug and the bottom of the barrel when the gun is in condition for firing. The forward end of the cooking lever is depressed to raise its rear end away from the hammer lug 3!V by engagement of the barrel 5 as the gun is closed with the hammer cocked. If the gun is of the double barrel type, two oscillatory levers 21, one for each ejector stem I2, will be mounted in the lug 26 with their upwardly extending arms y21a extending into operative relation with the respective ejector stems I2. Likewise, in such event two cooking levers are provided, one for each hammer of the double barreled gun. The dual cooking levers are mounted closely side by side intermediate the double hammers in the same relation with the lug 25.

In operation, the gun is broken in the usual way. As the barrel 5 with the forearm attached thereto is oscillated downwardly about the axis of the hinge connection 3, the rearwardly extending arm 6 of the forearm is raised relative to the frame 2 out of the slot therein. In such movement the top of the lug 26 carried by the arm 6 lifts the forward end of the cooking lever 29, thus inducing a cooking motion of the hammer lli, and

places the main spring I5 under initial tension. 'I'he elevated end of the cooking lever 29 subsequently slides off the nose of the lug 26, striking the beak 2lb of the ejector lever 21 with somewhat of a snap action under the reactive tension of the main spring I5. The pressure thus applied raises the opposite end 21a of the ejector lever 21 into thrust Yengagement with the forward end of the ejector stem I2 and thereby retracts the ejector II to eject the shell. As the oscillation of the barrel approaches the limit of its range of oscillatory motion, the end of the cooking lever 29 having depressed the engaged end of the lever 21 relative to the lug 26, is itself engaged by the shoulder of the lug formed by the notch 26a. The leverage of the barrel 5 relative to the arm E3, upon which the lug 26 is carried, is sufficient to forcibly raise the forward end of the cooking lever 29 and correspondingly depressing its rearward end against the hammer lug 30 thereby retracting the hammer against its action spring I 5, until the hammer shoulder 23 is engaged with the shoulder 22 of the sear I6. The action spring I5 thus duofunctionally energizes both the ejector Il and the hammer I4 to which it is common. Upon discharge of the gun, the hammer having been advanced to firing position by the reaction of the main spring I5, the lateral lug 3D of the hammer will be in proximate relation with the rear end of the cooking lever 29. As the forward end of the cooking lever 29 is elevated, the rear end thereof engages and bears upon the hammer lug 30 to restore the hammer against the tension of the spring I5, until the shoulder 22 of the sear IS again engages the detent shoulder 23 to retain the hammer in cocked position. It will be noted that actuation of the lever 21 to retract the ejector stem I2 and also the oscillation of the cooking lever 29'to restore the hammer occur during the opening movement of the gun while leverage is being exerted thereon by the swinging motion of the barrel. Consequently, the return or closing motion of the barrel is easily effected without resistance. The forearm is detachably engageable with the barrel by a conventional spring detent 3| engageable with a lug 32 upon the under side of the barrel. In disassembling the gun, the forearm is disengaged from the barrel which enables its grooved socket 8 to be withdrawn from the trunnion I formed on the end. of the frame 2 and the arm B to be withdrawn from the slot in the frame. This leaves the barrel engaged with the frame and stock by engagement of the semi-circular notch 9 of the lug I IJ with the inner side of lesser diameter of the trunnion 1 and the engagement of the usual latch with the breech of the barrel I. Upon release of the latch and tilting of the barrel, the lug I0 may be unhooked from the trunnion. The gun is assembled in reverse order. It is immaterial whether the gun is cocked or in discharged condition. The operation and ease of. engagement and disengagement is the same intbcth instances.

`i'rom the above description it will be 'apparent that` there isthus provided a'device of the character described possessing the particular features of advantage before enumerated as desirable, but which obviously is susceptibleof modification in its form, proportions, detail construction and arrangement of parts Without departing from the principle involved or sacrificing any of its advantages.

While in order to comply with the statute the invention has been described in language more or less `specific as to structural features, it is to be understood that the invention is not limited to the specic features shown, but that the means and construction herein disclosed comprise thepreferred form of several modes of putting the invention into effect, and the invention is therefore claimedin any of its forms or modifications withinithelegitimateand valid scopeof the appended claims.
