SHELL-EJECTOR FOR BREAKDOWN GUNS.

SEECFIC/ATION formingpart of Letters Patent No. 665,941, dated January 15, 1901.

Application filed September 26, 1899. Serial. No. 731,738. (N model.)

To all whom t may concern.'

Be it known that I, ELMER E. STUBBs, a citizen of the United States, residing at Jonesborough, in the county of Craighead and State of Arkansas, have invented a new and useful Ejector for Breech-Loading Shotguns, of which the following is a specification.

This invention relates to a new and useful improvement in an automatic shell ejector and extractor for breech-loading breakdown guns of preferably the double-barrel haminerless class.

One object of this present invention is to provide an automatic shell-ejector, which is also an extractor, which will be set or cocked ready to eject a shell upon the closing of the gun and not upon the opening of the gun, as is usual in devices of this character, and by which construction no additional Work is imposed upon the opening or breakdown action, leaving the same to perform its usual function of cooking the gun without requiring the application of additional force.

Another object of this invention is to provide a combined shell ejector and extractor whereby should the ejector mechanism fail to properly perform its designed function of ejecting or throwing out the empty shell, which is possible in any ejecting device under adverse conditions--such, for instance, as the swelling of the shells in damp weatherthe positive movement of the extractor will force the shell sufficiently out of the barrel to enable the operator' to grasp and withdraw the same by hand.

Another object of this invention is to provide means whereby when the gun is opened the ejector will operate only upon the shell or shells which has or have been fired or ex- 4o ploded, leaving the unexploded shell orshells in place in the gun.

Another object of the invention is to provide means whereby the ejector mechanism will be positively operated upon the opening of the gun to initially start the shell, after which the fired shell will be ejected by the impellent action of a spring whose energy is stored when the gun is closed.

The essential features of this invention reside, first, in the novel construction and arrangement of the ejecting mechanism proper;

second, in the novel means employed for operating the ejector proper; third, in the novel means employed whereby only the eX- ploded shell in the chamber of the gun will be ejected when the gun is opened, or, in other words, if both Bring-hammers have been tripped, which means that both shells have been exploded, both of said exploded shells will be ejected when the gun is opened; but if neither of the hammers has been tripped neither of the shells has been exploded and the opening of thegun will not eject either of the unexploded shells, and where one hammer only has been tripped only one shell will have been exploded, and that only will be ejected upon the opening of the gun, leaving the uneXploded shell in its chamber; fourth, in the novel construction of the divided ejector and extractor; fifth, in the novel construction and arrangement of the divided ejector and extractor stop-bolt; and, finally, the invention consists in the novel construe tion, arrangement, and combination of the several parts, all as will hereinafter be described and afterward pointed out in the claims.

I attain the objects heretofore referred to by the mechanism illustrated in the accompanying drawings, in which- Figure l is a longitudinal sectional View through one of the locks and a portion of one of the barrels of a hammerless breakdown breech-loading gun provided with my improved automatic shell ejector and extractor as the same appears when the gun is in a closed position and the hammer tripped after firing. Fig. 2 is a similar View to that of Fig. l, showing the gun in an open or broken position and the hammer cocked. Fig. 3 is a detail view of the breech end of the barrels, illustrating in position thereon the divided ejector employed in carrying out my invention. Fig. 4 is a side elevational view of one of the members of the divided ejector employed in carrying out myinvention. Fig. 5 is a plan View of both members of the divided ejector employed in carrying out my invention. Fig. 6 is a plan view of a portion of a gun and a portion of my improved ejector and extractor, together with ahorizontal sectional view of a portion of the barrels. Fig.

IOO

is a similar view to that of Fig. 8, with the' addition of the ejector thereto, and illustrates the parts as they appear when the gun has been fired and broken.

In the drawings, A indicates the frame, B the barrels, C the fore-end iron, which carries the barrels and which is pivoted to the forward end of the frame A, as is usual, D the hammers, E the sears, F the triggers, 'and G the mainsprings, all of said parts being practically of the usual and well-known construction.

The general construction and operation of a double-barrel hammerless breech-loading gun of the breakdown type are so well known that a detailed description of the same is deemed unnecessary; but for the purposes of introducing in this description myimproved shell ejector and extractor I will explain that when the gun is broken after one or both hammers are tripped the tripped hammer or hammers are cocked or moved rearwardly until a notch or shoulder thereon rides over and cooperates with the forward ends of the sears, which retain the hammers in such position against the tension of springs until the trigger or triggers of the gun are pulled.

The operation of opening the gun not only cocks the hammers, as above described, but also releases the ejector mechanism and allows the same to perform its function of ejecting the exploded shells; but this opening movement does not cock or set the ejectors, they having been cocked or set by the closing movement, which is an advantageous feature, for the reason that no more force is required to open a gun equipped with my improved ejector than would be required in opening a gun having no ejector, as I do not employ the opening movement of the gun to both cock the hammers and set the ejector, that work being divided, respectively, between the opening and closing of the gun. In other words, the opening movement of the gun releases the ejector and expels the empty shell, and the ejector is then reset or cocked, ready for the next ejectment by the closing movement of the gun. For the sake of clearness I will describe but one lock. While there are two represented in the drawings, they are substantially the same, and this is due to the fact that the drawings, as before stated, represent a double-barrel gun; but each lock acts independently of the other, and the operation of the mechanism would be substantially the same as a single-barrel gun.

In the forward portion of the frame of the gun and in vertical alinement with each ham mer is a cylindrical bore a, which is arranged on such a slant relative to the barrel of the gun that its axis will pass, preferably, below the pivot-point of the hammer D and above the hinge-pin ot' of the barrels. This bore is sufficiently deep to receive a suitable length of the coiled spring G, and axially in line with and opening into this bore a is a bore a" of smaller diameter, which bore a" is formed through the frame A.

H represents a plunger, preferably formed with a rearwardly-opening concavity h,which is arranged in the bore a and has secured to its forward end a rod h' and around which rod and interposed between the forward end of the plunger and the stock at the forward end of the bore a is arranged the expansible coiled spring Gr. The hammer D is provided with an extension d below its pivot-point, and pivotally secured to said extension is a dog or pusher-bar D", which protrudes into the concavity h and rests against the plunger This hammer D is provided with a shoulder, which `when the hammer is forced to its cocked position engages and is retained by the forward end of the sear E, and when in this position the pusher-bar D' has pushed the plunger and its carried rod forwardly against the tension of spring G, said movement also causingtheforward end of the rod h' to project beyond the partially-cylin d rical end of the frame A, the object and purpose of which will hereinafter be described.

Arranged in advance of the pivot-point of the barrel and secured to the fore-end iron C is a block I, upon and within which is mounted the mechanism employed for actuating and cooperating with the divided ejector and eX- tractor J.

The block I is provided with a verticallydisposed slot t', in which are mounted two pivoted tu mblers K K', two pivoted levers,which I Willterm tumbler-sears, L L', and two leaf-springs M M', which are preferably connected at one end to receive the securingsorew.

Directly above the rear portion ofthe block I and slidingly mounted in the rear portion of the fore-end iron C is what I will term the cooking-bar N, the forward end of which is designed to rest against the suitablyeurved rear faces of the tu mblers K K', while the rear ends of said cooking-bar rest in a forwardly-opening concavity 0 of what I will term the extractor-arm7 o', arranged on a sleeve O, located around the hingepin and between the forked end of the frame A.

`P represents a cap-piece screwed or otherwise fastened to the upper rearward portion of the fore-end iron, which is provided with a slot or recess p, which slot or recess is directly above the tuinblers K K' and allows the same in their rearward movement to pass thereinto, as shown in Fig. 8. Formed in the IOC IIC

lower rearward portion of this cap-piece P and opening into the slot or recessp are two parallel grooves, in which are arranged two parallel slidable ejector needles or bars Q Q', the forward ends of which touch and are in the path of movement of the tumblers K' K', while the rearward ends touch or abut against the forward ends of the divided ejector and extractor J. This divided ejector and extractor, which is shown more clearly in Figs. 3, 4, and 5 of the drawings, is constructed of practically two semicylindrical rodsjj, with their dat faces resting against each other. Arranged on the rear end of each of the rods jj are headsjwj", said heads being provided with suitable shoulders jm for receiving the rim or bead of the shell or cartridge, as is usual in extractors of this type. Suitable guide-pins jf are also provided for each of the heads j"j' forobvious reasons. These semicylindrical rods j j are provided with recesses 7'6 and j7, which when the ejector and extractor members are both in either their extreme forward or extreme rearward positions are in alinement with each other; but when only one of the rods is moved rearwardly said recesses are out of alinement, as is illustrated by dotted lines in Fig. 5.

The forward ends of the divided extractor are reduced to form on their adjacent faces shoulders, as shown in Fig. 5, against which the arm 0/ operates when the gun is being opened. The needle-bars Q and Q operate to move the two parts of the ejector or extractor independently of the arm 0', and, as shown in Fig. 6, said needle-bars are arranged on each side of the arm 0. This divided ejector and extractoris mounted in the breech portion of the barrels of the gun in the usual manner byallowingthe cylindrical rod formed of the two semicylindrical members to enter a suitable bore located below and midway between the chambers, suitable bores being also provided in the end of the breech for receiving the guide-pins R represents a pin or bolt which passes through the lug between the barrels and is designed to pass through the slot formed by the united recessesjj and is designed to arrest the semicylindrical rods in their rearward movement, as is clearly illustrated in Figs. 1, 2, and 6 of the drawings.

The block I is provided upon its sides with suitable longitudinal grooves t" 2", in which are bars S S, respectively held in their rearmost positions against the partially-cylindrical forward end of the frame A by springs s s, interposed between their forward ends and a bearing-block s". These sliding bars S S are so proportioned that their rear ends 3" are offset laterally from the bar proper, and their extreme rear ends are formed slightly convexed or curved, which enables them in the rearmost position of said bars to snugly iii the partially-cylindrical forward end of frame A, said ends 5 being also in alinement with the rods h', the ends of which are also formed with a curve of the same radius as the partially-cylindrical end of the frame A. Y

T indicates rockers or projections formed on the under sides of the slide-bars S S,which are designed to coperate with the projections l and Z on the tumbler-sears, respectively. The block I is secured to the fore-end iron by means of a suitable screw V, (see Figs. 8 and 9,) which passes through the concave portion of the block which is next adjacent the hinge` portion of the gun. It is of course understood that lateral movement of this block I is prevented by the anges u, which engage each side of the fore-end iron.

The operation of my improved shell ejector and extractor is as follows: As has been stated before, the ordinary operation of the breakdown gun shown in the drawings is that when either or both hammers are tripped the breaking or opening movement of the gun will reset or cock the tripped hammer or ham mers. When the hammers are cocked, as shown in Fig. 2, the plunger-rods h are projected forward and the slides S and S are held in a forward position, the rockers or projections T occupying positions in advance of the projections Z and l on the sears for the ejector-tumblers. Being in advance of said Sear projections, the sears for the ejector-tumblers are in engagement with the respective tumblers to the extent that the sears are in the paths of the shoulders on the tumblers; but there is sufficient clearance between said shoulders and the rear ends of said sears to permit the free movement of the sears. When the gun is closed, as shown in Fig. 8, the cocking-bar N is in engagement with both tumblers, forcing them slightly beyond a position where their shoulders will engage with the sears L and L', and in this manner all strain is removed from the ejectors proper, so that said ejectors will not crowd the breech of the gun. When one of the hammers has been tripped, as shown in Fig. 1, the controlled plungenrod h' is retracted, s0 as to permit the cooperating slide-bar S to move rearwardly, which movement forces the sear L to make an idle vibration-that is, said sear is depressed so that its end passes out of the path of the tumbler-shoulder, said sear end again returning to a position in the path of the shoulder on the ejector-tumbler. Assuming now that the gun is broken, the first movement is to force the extractor-arm 0 against the shoulders in the forward ends of the divided extractor, so as to positively move said extractor rearwardly. The con? tinued movement of breaking the gun next cocks the tripped hammer, which results in forcingvthe cooperating slide S forwardly and in so doing depresses the sear L out of the path of the shoulder on the tumbler K. As the cocking-bar N is now in a position to be projected into the recess o the moment that IOO IIO

tumbler K is released, it delivers an impacting blow against the needle-bar Q, which in turn engages with the left-hand side of the ejector and moves the same rearwardly beyond the position to which it had been moved by the action of the arm 0'. This quick hammer-like blow delivered by the tumbler K forces the left-hand side of the ejector rearwardly until it is arrested by the bolt R operating in the recess js thereof. The above description applies where the left barrel only has been fired, and it will be obvious that as the right barrel has not been fired the slide S occupies its forward position, so that the scar L' is in a position to arrest the tumbler K and prevent said tumbler from moving under the action of its spring M. In fact, when either of the slides S or S' occupy their forward positions before the gun is broken neither ofthe tumblers K orK wil be ltripped, but the arm 0' will always act to positively move the parts of the ejector to 'force the same and their carried shells rearwardly a slight distance, so that they can be grasped in the hand and taken out, if desired. It is only when the slides S or S occupy a rear position resulting from tripping their controlling-hammers that the opening movement of the gun will vibrate the ej ector-tumbler sears and release said tumblers. When the righti hand barrel is red, the empty shell from that side of the gun will be first moved positively by the arm o' and then ejected when the tumbler K is tripped. The positive movement above referred to also operates to move rearwardly the uniired shell, but not to eject it.

From the above it will be seen that when` either one or both barrels of a gun are fired the ejector mechanism will operate to throw the empty shell from the gun. When the shells are not tired, however, only the extractor will work to place the unfired shells in position to be grasped by the hand of the operator, if desired.

I am aware that minor changes in the arrangement, construction, and combination of several parts of my device may be made and substituted for those herein shown and described without in the least departing from the nature and principle of my invention.
