To all whom it may concern.- 7

Be it known, that T, Mosns A. Kant an, a

citizen of the United States, residing at Batavia,i the county of Genesee and State of New ork, have invented a new and useful Improvement in Automatic Shell-Ejectors for Breech-Loading Guns, of which the following is a specification.

My invention relates to improvements in automatic shell ejectors in which the main springs of the locks are employed for power to actuate the mechanism; and the objects of my improvement are, first, to provide an automatic shell ejector which will work independent of the cooking aotienof-thelocks so that the latter will always cock before the shells are knocked out, and without necessitating the opening of the gun any further .than is necessary to allow the shell to pass, out over the frame, second in getting the full power of the main springs of the locks to operate on the ejector mechanism toforce the shell out; and it consists in various other important features hereinafter pointed out, and whichl attain by the mechanism illustrated in the accompanying drawings, in which- Figure, 1, is a longitudinal sectional view through one of the locks, andmy improvements, as the same would appear when the gun is closed and the parts in their normal position, and with the firing hammer in full,

cock. Fig., 2, is a similar view as Fig. 1, but with the firing hammers let down, or as the same would appear after the gun had been 3 5 fired, and before the same was opened for reloading. Fig., 3, 1s a similar sectional view as the two preceding figures, but with the act-ion partially opened, and the locks about half cocked. Fig, 4, is a similar sectional mal position at full cock. Fig. 7, is a sec-.

tional view of the forward end of the main frame carrying .themain springs and parts of the ejector actuating mechanism, and Figs.

8, and 9, are detail views of the fore-end and ejector hammers.

Similar letters refer to similar parts th rough- 5 5 out the several views, as will appear in the following specification.

The mechanism illustrated in the annexed drawings represents the well known Parker Bros. hammer-less, double barreled shot gun, .60 and my improvements, relate to automatic shell ejectors, in combination with the pecu liar lock actions of this gun, or guns having a similar lock action using a coiled main spring, and mechanism compressing the main spring simultaneously from both ends, in the act ofopeninithe gun for cooking and reloading, it a ter'bei'n'g' fired therebyJhaVing the full force of the main springs to actuate the shell ejector mechanism, and without tilt- 7o ing the barrels any further than is necessary to allow the shells to pass out over the frame.

For the sake of convenience Lwjll describe but one look. While there are two repre-. sented in-the drawings they are precisely the 7 5 same, and this is due to the fact that the drawings represent a double gun, but each lock acts independent of the other, and the operation of the mechanism would be substantially the same in a single barrel gun.

E represents the main spring, b, the main cocking plunger of the lock, and S the supplemental plunger or compressing disk of the ejector mechanism, these three members are loosely fitted into a hole drilled in t'he'frame A, forward of the firinghammer M. The compressing plunger b, is provided witha long rod h, extending through the springE, and through .a hole in the disk S, and a hole in the end of the frame, into the slot H, as plainly shown in-all the drawings except 5, 8 and 9, a cam lever F, is fitted into the slot H, and journaled upon a pin .0, and is free to vibrate up and down in theslot, during the operation with the opening and-closing of the gun for 5 reloading, the compressing disk S, has a short stem projecting into the slot H, and bearing against the cam portion of the lever E', as shown in Fig; 7. The hammer M, is journaled upon the pin 0, which is secured in the 1oo' frame A,-pivoted to thelower end of the said hammer isa small pushinglever c, and which enters the hollow of the plunger b, and holds said plunger up against the spring E, and

a acacia through which the. spring communicates its; to Fig. 1., ;we have the whole action in ite usual position powerto the'hammer. Referring -P,'a pin I, limitsits-forward .niov'ement and retainsit in its place. Now when the action is iii-tine position shownv in Fig. 1, the rod h,

is pushed out beyond theframe A, and up againstthesear N, and forcesthe latter against the resistance of the-spring P, and holds the sear N, out ofaction'with 't'he'leve'r F, and as long,as the hammer M, is at full cock as is shown inFig. 1, the gun can be opened and closed withouthaving the loaded shell knocked out, of the gun, but .when the gun is fired so or hammer let down-as shown in Fig. 2, the rod h, recedes from the sear N, and the spring P, forces the sear forward which catches over the' end of the inverse represented by g, in

Fig. 2. Now when the gun is opened and as barrels B, which are hinged upon the pin I), begin to tilt,-the lever F, is carried down in the slot and by this action forces the disk S, back against the spring E,-until the breech end of the barrels is high :enough to 0 allow the shells to pass out over the frame A, this'position is shown in Fig. .3, anda little later in Fig. 4, the leverFbeingpivotedat a point eccentric to the hinge pin D, it becomes shorter as the barrels continue to tilt, until it slips oil the scarN, and strikes the short arm j, of the ejector hammer t, and forces the latter against the rod of the shell ejector L, in the manner shown in Fig. 4, and the shell is thnsknockedout of the barrel, simultaneously .0 with the opening of the the hammers M, takes place, which is-attained throu'ghthe lever R, cockin g crank G, and the slide F, the latter hooks ovcra heel formed at the lower end of 1 hel1am mer M, the crank G, 5 is pivoted in the frame A, its lower end engages a mortise in the slide F, and its upper end is provided with a pin that hooks into the lever R, that is pivoted into the mainlug of the barrels all plainly shown in Fig; 5, it will be seen by this construction, that the short lever c pivoted plunger 1), against the main spring E,and compresses the latter in the act of opening the gun after the hammer M, had been snapped or let 5 5 down, and the same time the rod, h, is pushed out. And as the gun is again closed, the rod h, comes in collision with the searN, and holds the same back in the position shown in Fig.

, 1, the sear d, holds the hammer M, cocked until relieved by a pull on the trigger.

It will be seen by reference to Fig. 3, that the main spring E, is compressed simultaneously from both ends, by the disk S, and the plunger 1), in the act of opening the gun after firing, and the spring gains its greatest force at the moment the lever- F, slips ed the sear N, and thus forces the lever F upon the arm of the main spring,

gun, the cooking of to the hammer M, forces the j, of the forced ,home,

as-shown-in Figs. 4; and 6. It will be seen by "this. arrangement and construction, the cooking of the hammers M, and

leaving. them underthe full power'ofth ,spring is not interfered with'v bytheworking throughthe power of the ejector mechanism, H

nor necessitate the -tilt- .in g of the barrels further after thesh'ells-have ejectorhammere, until-therdisk S, is.

been knocked out, in order to ofckthe firing-ghammers, as the cooking of thehammers M, and the knocking out the shells are simultaneons as the barrels reach tl 1e limit .of tilt, at the point shown in- Fig. 4,101 thetiming of the parts is such that the hammers, M, cook a little prior to-the knocking out the shells, thus making. sure that the hammers are cooked, and ready for closing them when loaded.' 1 I Having thus fully described my invention, what I claim and desire to secure by' Letters Patent, is, V 1.
