EJECTiNG MECHANISM FOR BREAKDOWN GUNS.

BECIFICATION forming part of Letters Patent No. 532,096, dated January 8, 18-95 Application filed June81l894. Serial No. 513,939. (No model.)

To aZZ whom it may concern:

Be it known that I, JOSEPH RIDER, a citizen of the United States, residing at Newark, in the county of Licking and State of 'Ohio, have invented certain new and useful Improvements in Breakdown Guns, of which the following is a specification.

This invention relates to breech loading guns of that class known as break down guns, and the invention consists in a new style of automatic ejector-s, which also serve to start the shells, and in certain other features, all

' as hereinafter more fully set forth.

Figure 1 is a side elevation partly in section, showing the gun closed. Fig. 2 is a similar view, showing the barrels tipped to eject the shells. Fig. 3-is -a side elevation; partly in section, showing the ejector nearly in position to eject the shell. Fig.4 is a similar view showing the position of the parts at theinstant that the ejeetorcommencesto eject the shell; and Fig. 5 is a similar view'illustrating a modification of the ejector. Figs. 5, 6, 7, 8 9, 10, 11, 12, 13, 14, 15,16 and 17 are views of parts shown in detail. Fig. 18 is a perspective View of the ejectors and their frames detached, andFig. 19is a perspective View of the front end of the frame to which the barrels are hinged, showing the stop pins which limit the tip of the barrels, and also the front ends of the sliding rods which engage with and operate the lifting bars of the ejeet'ors.

This inventionis an improvement on the gun-for which Patents N 0.500,949, dated July 4:, 1893, and'No. 511,362, dated December 26,

1893, were issued to me.

The construction of the frameand safety device are the same asin my former patents, and need not, therefore, be described; In its general form the lockmechanism is the same .also, with the exception of certain improve-' ments which I will now proceed to describe.

The hammer II, with its laterally project ing tumbler a and cooking arm 9', are made as before, in a single solid piece, but the arm 0' is made longer and slightly different in shape, and is shown clearly in Figs. 1, 2, 11 and 12. I also use the same form of spring S arranged to serve both as a main spring and also as a trigger spring, as described in my former Patent No. 500,949, and as shown in Fig. 1; but in order to'secure a rebound ot the hammer, I now make'the spring with a vertically. depending lip 19' at its frontend, as shown in Fig. 12, this lip resting loosely in a slot 11. cut in the rear side ot the tumbler a with its point below the axis or journalof the hammer,'as shownin Fig. 12, the parts being so proportioned and arranged that when the hammer delivers its blow, the bearing of the spring on the tumbler will be transferred from the shoulder r above the axis, to the point of the lip below the axis, which willerally projecting arm 8 which engagesin a notch 11. in the upper .side of the trigger 15,

shown detached in Fig. 16, these parts all\be-- ing shown in positionin Figs. 1 and 2.

In order to enable the barrels A to be more easily dismounted, instead of the solid lug, I

now pivot to the barrels near their rear ends, a hook shaped piece 12, as shown in Figs. 1, 2

and 6.- The form of this piece is shown more fulLy'in Fig. 7, in which it will be seen that its upper end is provided on its rear side with a shoulder y, on which, as shown in Fig. 6, a spring e is arranged to bear, by which the lower end of piece I) is thrown forward, as shownin Fig. 6, thus freeing it entirely from the cockingarms, and the stoppin o, located in the frame A'as shown in Fig. 19, and enabling the barrels to be removed at once. As shown in Fig. 7, this piece 12- has across its lower end a projection 0, upon the top of which the cooking arms engage when the'barrels are dropped, thus automatically cooking the hammers as shown in Fig. 2, the ends of this projection or cross head striking against the stop pins 1), just as the hammers are fully cooked, thereby limiting the tip ofthe barrels.

In order to shove the piece I) backward and held it in .positionto engagew'ith the cock-.

ing aims and the stop pins, I bore a hole 1ongitudinally through the hinge lugL, and place loosely therein a small rod f, as shown in Fig. 6, the rear end of this red f bearing against the piece Zigvhile. its; front end projects beyondthe lug,- so that when-theej ec'to r frame I'is placed in position, it will push the roll f back far enough to swing the piece I) back to the proper position to engage with the cook ing arms and the stop pins, as shownin Figs. .1 and 2, the stop pins 22 being shown in'dotted line in'Fig. 2. Themoment the fore end of the'stock in which the extractor frame is set is removed, the'spring e throws the lower.

end of piece b forward to the position shown in Fig. 6, when the barrels can be hooked from the frame. i

'Heretofo're in this class of guns,when automatic ejectors were used,.i t has been customary to first start the shells by aprojection A at 'onceunsecured to the frame at its front end, against .which the stems ofthe' extractors engaged as the barrels were dropped, such being shown in .my former patents. In the present in-- stance I use a new style of ejcctors, which also serves to start the shells, as well as to eject them subsequently. These ejectors which I' will now describe, areshown clearly in Figs. 1, 2, 3, 4 and 5, and with their framescomplete,

in Fig. 18. They-consist ofv three parts, viz:

an ejector hammer h, an operatingbar g, and a spring These parts are made in the forms shown, andare mounted in a metallic frame I,

as shown in theseveralfigdnesni .Theham m ers. it, one for each barrel,-are.provided with a head 'to bear against theends of the extractor .ste'ms E 'as shown in Figs. 3 and. 4, and with,

- a too to engage witha'notchin the rear face of the upright part c of the bar g. The bar has its free end, where it bears upon the pin, formed with an incline m as shown in .the sevg has a longitudinal body, and atitsrear end is provided with an upright arm 0, the upper end ofwhich is beveled or inclined on both its front and rear faces, and with ,right' angled shoulders below, the space between the front shoulder and the body' of the bar forming a notch or recess n, in which, at the proper time, the toe of the hammer hi engages, as

shown in Fig. 4-. This bar 9 is also, provided on its under side witha ,couple of fiangesn through which a pin isinserted for the' fsprin g k to bear upon, as shown, the bar being placed loosely in the frame so as to permit of a slight endwise movement to andfro. The springk.

eral figures, and which incline may be formedbyan enlargement of the spring at that point, or by a bend in thespring, as found rn'ostco'nvenient.

1 "A small sliding; bolt Z, shown detached in Fig.8, is located loosely in a hole in the frame, .60

in a line between the main hammersH of the gun and the upright c of bar 9, as shown in Fig. Land in dotted lines in Fig. 2. The front ends of these bolts, which I,term lifting latches, are beveled on their under sides, as

shown in Figs. 1, 2, 3 and 4, and are offset laterally as [shown in Fig. 8 to bring their points in line with the u'prightsc of the bars are forced-forward by the hammers Hit e" in Figs. 1 and 3.

,as the barrels begin-to'tip, the point of the latch I will raiseithe rear end of bar g, therewhich restson the bar, and causing the faceof-the hammer. to press against the end of The toe o of the ejcctorhamme'rbeing ear- .conseqiiently the bar g, backward, this moveare brought into alignment or coincidence,

upper wall or shoulder is; engaged over. the

carries the rear shoulder of upright-c offand end of bar 9 being thus made free, isinstantly a sudden impulse to the ejector hammer, which in turn gives alike sudden movement from the barrel.- At the same timetheinthe under beveled face of the lifting latch Z, thereby shoving that back, when the several tions. i In Fig. 5 I have my ejector. Injthis I use a bent spring, placed above the bang, 'and'onthe bar at the point wherethe spring bears, I make an inclinep on which the point of the spring operates to draw the bar back, the same as does the inin lieu of this, the rear-end of the ar gmay have anincline on its under side bearing on a correspondingincline,assho wn at 10 Either ofthese will cause the bar to move backward when released from the lifting latch, just the same as whenthe incline is made: on the spring, though I prefer to make the incline on the'spring. It will be seen that by this and that when the gun is closed the ejector hammers lie loose upon the bar 9, as repre-v same as in my Patent No.-5 11,362,-by' which? The parts beingthus constructed and. ar ranged, the operation is as follows: Supposeing the gun to havebeen' fired, the various parts will be in the positions shown in Fig. 1,, in which it'will'be observed that theback of the ejector hammer h rests on the bar 9, while the face of thehammer touches orvery nearly touches the end of the extract-or stem -E. Now' the extractor stem, and thus to start the shell.

to the extractor E, thereby ejecting the shell arrangement the ejector springs are under tension only'during the tipping of the barrels,

(1, w hen the gunis fired, these lifti xiatehsf their points-are made to project from the. front end of the frame A, as showninFigsil,

2, 3, 4 and 19, so as to engage underthe rear. shoulder of the-upright c of the bar mas-shown ,-85., by at'the same time raising the hammer 9 ried downward in contact'withthe inclinedfaceof upright c, forces said upright, and

ment continuing until the too O and. notch n- 9S whereupon the bar 'g-is moved forward by the action ofthe'incline mof spring K and its the closed. position, the rear inclinehof-tlre upright c.wi ll be brought into contact with parts will haveassumedtheir original posi- I v '115 shown a modificati'onof I clin'e m on the spring in the other case or,

- seaoee 3 sented in Fig. 1, and thus all parts of the ejecting devices are freed from strain at all times except during the time occupied in dropping the barrels. By this construction I not only produce a most eificient automatic ejector, but also make the 'ejectors serve to startthe shells preparatory to their ejection.

- It will'of course be. understood that two separate extractors are used, one fior each barrel, the same as in my Patent No. 511,362,

and that consequently the shell will be started and ejected only from the barrelthat has been fired. If both barrelscbe fired, the shells will be ejected from both; but if only one barrel be fired, thenthe shell will be ejected from that one,.while the shell in the other barrel will not even be started; because, unless the gun hammer be let down, the lifting latch will not bedriven forward to engage with the upright of bar g, and. consequently the ejector hammer of that side will not be moved at all. r T

It is to be noted that the bar 9 acts positively upon the ejector hammer h during the initial movement of the barrel in opening, thus insuring the starting of the shell and affording adequate power to that end, and the invention is therefore to be'distinguished from constructions in which the entire oper-. ation of starting the shell and ejecting it is by spring pressure,'thoughtvarying in leverage and in quickness of movement. words, the initial movement is a positive movement, with abundant power to start a tight shell; and the final movement is a sudd en spring-produced movemen t.

Having thus described my invention, what? I claim is- 1. In combination, thehammer I-I provided with a laterally projecting tumbler a, having a vertical notch '26 therein, and thecnrved spring 5 provided with thedepending" ,lip 'or projection 12 arranged to rest in said notch with its point below the axis of the hammer, for the two-fold purpose of causing arebonnd the spring from lateral displacement.

2. In combination with the main frame and barrels of a gun, the piece or link b, pivoted at its upper end; spring 0 bearing upon the of the hammer and holding the front end of link 6; push rod f, bearing against the forward side of the link belowthe pivot of the In other and frame B, extractor E; ejector hammer 11 4 provided with toe 0; bar g provided with upright 0 shouldered on its front and rear faces.

and provided with an inclinedfront face; spring K; and lit'ting latchl. r

-4. In a gun, the combination with an ejecting hammer h and with a bar g adapted to engage and move said hammer, a sliding latch bar Z located in theframe A between the gun hammer l1 and the bar g, and adapted to hold up the rear end of said bar while the tee of the ejecting, hammer rides downward over the same preparatory to engagement of the bar with said toe.-

5. In a breakdown gun, the combination of a main frame, a barrel pivoted thereto; an e: tractor; an ejector hammer adapted to bear against the extractor; a bar or lever carried by the barrel and adapted to bear against the ejector hammer during the initial tipping of the barrel and then to engage with said ham mer; a sliding latch adapted to engage with saidbar duringthe initial tipping of the bar- 'rel; and a spring to move the bar and hammer suddenly during the latter portion of-the tipping movement of the barrel, substantially as set forth.

6. In a break-down gun, the combination of a pivoted ejector hammer arranged to bearnormally against the extractor stem, a bar and spring for operating the same, and a sliding bar arranged to lock said hammer and cause it to start the extractor by a positive motion dnringthe initial tipping or dropping of the barrel and then releasing it during thelatter portion of the tipping movement, sub! stantially as described, whereby the extractor hammer is caused to start the shell, then eject it, and the spring .beireleased from tension.

at all times except during the tipping of the barrel. In witness whereof I hereunto set my hand in the presence of two witnesses;
