To ali whom it may concern..- 7

Be it known that I, \VILLIAM II. DAvEN- com, a citizen of the United States, residing at Norwich, in the county of New London and State of Connecticut, have invented certain new and useful Improvements in a Combined 'Shell Extractor and-Ejector for Breakdown Guns; and I do hereby declare the following to be a full, elear,and exact description of the invent ion, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accomrpan'ying drawings, and to letters of reference "niaiked thereon, which form a part of this 5 I specification. 7 A i g This invention relates to shell-ejector so called ,for breakdown gunsorfirearms and itconsists, essentially, of a device combining an ad] ustable spring-resisted extractor-rod, a locking-pin, and a lever connected with it and said rod, whereby the first part of the movement, as in opening theggun, operates I to positively force or-cntract theadhering a is down guns.

"shell from its"seat,' such movement being times liable to stick or adhere snugly to thebarrel, or, in other words, it'was possible that the force of the spring would not in all cases extract and eject t-he shell. Consequently the device was not strictly positive or reliable in its action, since the springitself was the only shell-moving means employed. In the said device a lockin g-pin was also eniployed,but all the force or power available to move the shell from the barrehse'at was that residing .in the spring, as just stated. In my present invention'a marked difference in the construction and arrangement over said patented device residesin thc'f act that the shell, in case it tightly adheres to the barrel, is positively extracted or started from its seat irrespective of the spring force, the l'atterin sucheasebeing v shell is, or may be, thrown entirelyont of the barrel.

In the accompanying drawings, Figure 1 is a side elevation, in partial central section, of a breakdown gun provided with my improvement, the several partsbeing represented in the normal-position. Fig. 2 is a similarlview, the barrel beingpartly tilted andv showing a shell snugly adhering to the barrel, the extraeting-lever' of the device being in the act of forcing the shell rcarwardly. Fig. 3 isa similar view showing thebarrel fully tilted or dropped, the locking-pin withdrawn, the shell having been extracted by means of the lever, and the force of the-spring operating to eject the shellentirely from the barrel, as shown by dotted lines; and Fig. 4 is a transverse sectional view of the barrel, taken on line :1 .1 of Fig. 1, showing the forward end'of the gun-frame and the parts mounted therein. My improvement like many others of .this class is well adapted to be used in breakdown shotguns provided with any well-known looking and firing mechanisms, and I .Inake no claim herewith to such instrumentalit-ios.

' In the drawings, 1) indicates the usual barrel memberprovided on its undcrsidewith a. lug h"; f, the frame secured. to thebreechstoek; h, the hammer; t, thetrigger; Z, the

topsnap-leveiythrodghwhichthelocking-bolt I m is operated; p, a removable pin or screwkey 'passingthrough the forward-part of the frame andbarrel-lug andforming a pivot on which the barrel may betilteihand f the f0re w0od secured to the barreland fitted. to

the semicircular end b of the frame.-

The forward portion b of the barrel-lug Z) is slotted to' receive thecombined tripping and forcing or extracting lever c. Said lever is provided with two arms arranged at substantially right angles to each other. The

longer of said arms extends longitudinally of the log and is V-shaped at its free end, as at tends vertically and is adapted to frictionally contact with the free end of a pin or extension 'r of the extractor-rod a. The heel or knee portion of the. lever is adapted to swing below the barrel-lug, so that when the barrel is being tilted from the normal position it will engage the adjacent surface f of the frame. The lever is mounted to swing on a pivot-pin c fixed in the lug and located about, midway between said knee 0 andpoint 0.

Thebarrel at its junction with the lug b is drilled longitudinally to receive the eX- tractor-rod a. The latter, as drawn, is not of uniform diameter throughout its length, the forward portion 1 being somewhat smaller and screwed into the rod, as shown at 0, Figs. and 2. If desired, said part 1' may be simply a loose piece of steel interposed between and in contact with the screw-head 0 and the rear face of the upright arm of lever c. A spiral spring surrounds the small rod 9', a fixed pin or stop 15 Fig 4, serving as an abutment for the forward end of the spring. Thus it willbe apparent that the expansive force of the spring acts to press the extractor-- rod rearwardly.

The extractor member a. is rgund and is provided with an enlarged head it at its rear end, the latter being seated in a correspondingly-shaped recess formed in the barrel and lug. The upper side of head a is cut away, as at a the same beinga continuation of the counterbore 72 formed in the end of the barrel for the reception ofthe shells rim, as clearly shown; The under side' of the extractor a is provided with an elongated notch n capable of receiving the beveled upper end of the said locking-pin n. .It is also provided with a slot d, into which the upper end of the screw-pin d enters.

- to prevent the extractor from turning axially as well as to arrest and limit its-rearward movement. 4 I e From the foregoing description it will be apparent that after withdrawing the bolt m, through the medium of the top snap-lever}, the initial part of the act of tilting or drop ping the barrel, as in opening the gun; will ,cause the heel c of the .lever to contact with the suitably-shaped surface f of the frame, thereby at the same time swinging the vertical arm of the lever both upwardly and rearwardlya'nd thus positively forcing the extractor rearwardly from its seat, or, mother words, Fig. 2 shows the relation of the parts upon an adhering-shell at the instant the heel of the-lever contacts with the frame. The

continued movement of the barrel to theposition shown in Fig. 3 withdraws the lockingpinn from the notch n, and atthe same time forces the shell from its seat,.s0 that the ex- Fig.- 3.

This latter serves tractor when thus released or freed is capable of being acted upon by the spring t, which latter in turn operates to forcibly move the extractor-rod to its limit, or until arrested by the face f of the frame, and thus eject the empty shells from the barrel of the gun. (See I would add that in order o provide means whereby the tension of the ejector-spring t may be adjusted or regulated I prefer to tap the forward part of the extractor-rod, into which part is fitted a screw-threaded tip 0. The said steel extension 1 may be integral with 0 or not, as desired, and having its front end enlarged, so as to provide a better bearing-surface for the lever c. arrangement of the parts a, f, and the head a of the extractor are such as to fully withdraw the locking-pin from the extractor at-or about the same time that the lower sideof the bore of the barrel, as the latter is tilted, passes above the top edge of the frame.

- In closing the gun the rear face of -the extractor-head slides downward against the vertical face f of the frame, thereby forcing the spring-resisted extractor ahead to its seat. Fig. 1 shows the relation of the parts when the gun is fully closed. Thus it will be apparent that the initial action of the device is positive with respect to extracting or forcing the shell from its seat in the barrel and is sup plemented by the reaction of the spring t,

which operates to completely eject the shell i event, however, the construction and arrange ment of the parts are such that the lockingpin is not fully withdrawn from the extractorrod until the rear'part of the barrel is elevated sufiicient-ly to permit the shellto'pass the upper part of the .frame, andsuch complete withdrawal of the pin occurs nearly The form andconcurrently with the final movement of the barrel. I

I prefer to so proportion the partsand time their movements that the head end a. of the extractor-rod willpractically ,be in engage-- ment with the vertical face" f of the frame during the major part of the barrels move I ment. h

I claim as my invention- 1. n abreakdown gun, the combined shell extracting and ejecting device hereinbefore described, the same consisting of the endwisemovable notched rod member a mounted in the lower portion of the barrel, 'a verticallyarranged locking-pin in normal engagement with the notched portion of said rod, a mov able extension member 1' located at the forward end of the rod a, a spring adapted to keep said parts a and r normally separated, I

and -ne COmblDeu tripping and forcing lever c pivotally mounted in the barrel-lug and in practically continuous engagement with said locking-pin and extension member, constructed and arranged whereby the act of tilting the barrel, as in opening the gun, causes the said lever c to forcibly engage the gunfra-me, thereby at the same time positively withdrawing the locking-pin from the notch and forcing theextractor-rod rearwardly and permitting the spring to simultaneously eject the latter outwardly to its limit, for the purpose set forth.

2. Ina breakdown gun, provided with the usual ad junctive devices, the combination with the recessed frame and the barrel member pivoted thereto having a lug, b, on its under side, of a spring-actuated notched extractor-rod movably mounted in the lower portion of the barrel, means for maintaining the rod in position axially, a vertically-movable locking-pin,- '12, mounted in the barrellug adapted to engage the notched portion of said rod, and an L-shaped lever, c, pivoted to the lug having an arm in engagement with said locking-pin, the other arm normallyconsaid rod member, the extension or shortlod member 1 located in front of said screw, the ejector-spring t in engagement with and normally separating the screw and the extension member, and having the vertical arm of said lever c in substantially continuous engage ment with the front end of the short rod 0", substantially as hereinbefore described.

In testimony whereof I have aifixed my Sig nature in presence of two witnesses.
