The trigger :22 is pivoted at 23 in the o provi dedon itsupper portion? provided'with shoulders '25 tang 101 It is 25 engages the sear-arm 27. Theshoulder gger 22isj stopped l shoulder26 upon .of the single-trigger engagement with the stop 29 on the safety-lug 30. When the safety catch 6 is moved rearwardly, the projection 31 forces the safety-lug 3O rearwardly, with the result that the stop 29 falls into a position above the ear 27 and prevents the pulling of the choke-trigger. The safety-lug is to be held in contact with the projection 31 by a coil spring 32 resting upon the lower tanglO. The spring 33 provides a friction and catch for the safety, holding it either in open or closed position. The safety-lug 30 is pivoted at 34 in the flange 35 of the lower tang 10 and when pushed rearwardly into safety position, as shown inFig. 6, the ear 37 of the safety-lug overhangs the shoulder 36 21 and prevents pulling of that trigger. When the safety-catch 6 is released, the safety-lug 30 swings forward, swinging the ear 37.rearwardly and out of the shoulder 36.

30 also serves to prevent involuntary firing of a second barrel during recoilof the gun. In that stage following the recoil'where the gun is moving forward on a rebound from the shoulder of the shooter or a recoil chamber, and the trigger is thereby pressed against the finger of the shooter, the inertia of the safety lug 30 carries it backward relatively into the same position occupied by it when in safety, and thereby prevents firing of the gun.

The single-trigger 21 is provided with a rearwardly extending flange 38, which is in constant engagement with the plate 40. A selector pan 41, which pivots upon the pin 42 is carried on the plate 40. Both the plate 40 and the selector pan41 are movably mounted, as for example, pivoted upon the pin 39, which is journaled in the selector-post 29. When the single-trigger 21 is pulled, the plate 40 and the selector pan 41 are lifted and upon successive pulls of the trigger the se-- lector pan successively engages the sear-arms 28a, 28b and 280, thereby raising the sears 14a, 14b and 140 in succession and firing the hammers 11a, 11b and 110.

The plate 40 with the flange 38 by a spring 83 fastened in the lower tang 10. The sear 14a may be held up by a sear spring 84 on the lower tang 10.

The action of the selector pan is illustrated The safety-lug in Figs. 11-17. In Figs. 11 and 12, the posi tion of the parts is shown with the gun fully cocked. As shown in Fig. 12, the left prong of the selector pan rests below the sear-arm 28a of the left-hand sear 14a. Upon pulling of the trigger 21 the table 40 is lifted, carrying with it the selector pan 41, which engages the sear-arm'28a, therebylowering the nose 15a ofthe sear and firing the hammer 11a. The'sear 14a is provided with a sear-hook 43a, which holds the fingers of the W table 44 in horizontal position against the spring 45. When the sear 14a is raised, the spring 45 forces the right side of the W downwardly,

may be maintained in contact and brings the left finger 46 of the W table into engagement with the sear-hook 43b of the seal 14?). At this point the right finger 47 engages the stop 53. pivoted at 48 and is provided with a downwardly extending projection 49, which in turn is provided with a rearwardly projecting lug 50, as shown in Fig. 17. When the left finger 46 of the W table is raised, the lug 50 is swung to the left, thereby engaging the left prong-51a of the selector pan 41 and moving the selector pan intothe position shown in Figs. 13 and 14.

Upon again pulling the trigger 21, the sear-arm 28b of the sear 14b is engaged by the selector pan, as shown in Fig. 14, and the hammer 11b thereby fired. After thefall of the hammer 11?), the sear is pulledback by 1 its sear spring, thereby depressing the searhook 43?). i

The sear-hook 43b ofthe sear 14b in its The W table is downward progress engages the left finger v 46 of the W table and draws it downwardly until it engages the stop 52, as shown in Fig. 15, the sear spring pulling down the searhoolr 43?) being more powerful than the spring 45. The action of the sear-hook 43?) upon the W table causes-the lug 50to move the selector pan to the right and brings it into the position shown in Fig. 16, in which the right prong of the selector pan underlies the sear-arm 280. I v N I Upon pulling thetrigger a third time the selector pan engages the right-hand sear 140, thereby releasing the right-hand hammer 110. After firing thesear spring 54 of the sear 140 returns the sear to position, thereby pulling down the sear-hook 430 and thereby pulling the W table back to a horizontal position. The sear-hookl is prevented from falling any lower bythe shoulder 25 on the choke-trigger22. Thetrigger itself. is prevented from being pushed lower by the notch 55', which catches upon the 1 lower tang 10,.

as shown inFig. 4. j i

It will also be seen that, regardless of when the choke-trigger 22 is pulled, the action of the selecting mechanism is. not interfered with, since the sear hook 430. after firing simply prevents the right side of the W table from rising abovethe left, and the firing position for the other barrels does not require that the right side be raised above the left. a

' The ejector mechanism of the gun is so constructed that the ejector hammer and ejector pin for the middle or top barrel 2?) is elongated and operates through slots. The ejector hammers for the other barrels may operate in any conventional manner. example, as shown in Figs. 18-25, ejector hammers 56a, 56b and 560 are provided, hammers 56a and 560being of customary dimensions, but Hammer 56?) being elongated to such an eXtentas to reach the extractor For I stem 57b below the barrel 2b. The ejectorshown in Figs. tand 6-, thefiring ham- Iners 11a, 11b and llc'are .provided with 1 lower ears 60a, 60b and 600, which engage the hammers are fired, the rearward ends of the cooking rods are thereby depressed by the ears 60a, 60b and'600. The cooking rods 7 are pivoted at 62, sothat upon firing of the 15 gun the forward end of each cocking'rodis raised as its respective hammer falls. The cocking rods are respectively provided at their forward ends with hooks 64a, 64rb-and 64c. WVhen the barrels 11a or 110 have been fired, hooks 64a or 640 are brought to a position, where, upon breaking of the gun, they will engage the cams 65a or 650. The cams 65a and 650 are pivoted on the .pin 58 with the ejector hammers 56a and 560 andare provided with ears 67 a and 67 c engag ng springs, for example such as the compression springs 68a and 680. When the gun has been fired, breaking of the gun'causes the hooks 64a and 640 to engage the cams 65a and 65a and causes them to swing forward on the pin 58, thereby releasing the springs 68a and 680 against the ejector hammers 56a and 560 and forcing out the extractor stems 57a and 57 0 which eject the exploded shells.

When the hammer 11?) has been fired, the hook 647) on the forward'end of the cocking rod 616 is raised to a point where, on breakdown, it will engage the notch 59 on the ejector hammer 1565, thereby pushing the ejector hammer forwardly on the pm 69, re-

leasing the compression spring 68?), and

thereby propelling the ejector hammer'forward and ejecting the shell from the barrel 2b.

The gun is likewise provided with an extractor pin 70, which may be secured r gidly in the firing mechanism, for example, in the stem 71, upon which the gun pivots when broken. The extractor pin extends through the slots 7 2a and 720 in the extractor stems 57a and 570 and into the slot 73?). The slots 72a and 720 are preferably complementarily notched so as to each provide one-half of the complete slot. Upon breaking of the gun, the extractor pin is pressed into engagement with the shoulders 7 3a, 7 3b and 7 30 of the extractor stems, at the rearward end of the slots 72a, 7 2b and 720, and there-by pushes out the shells in each barrel. The distance may be regulated by the dimensions and angle of the pin, but is preferably about one-fourthinch. As a result it is possible to remove unfired shells.

When a barrel has been fired, however, the ejector hammer is brought into play and the the cooking rods 61a, 61b and 610. When shells are ejected, the movement of the ex-, tractor stems being stopped by the impinge ment of the shoulders-74a, 74b and 7 40, upon the extractorpin. I V

The gun maybe cocked 57a, 57?) and 57 0' are pressed back into posi-.

tion by the extractor pin which engages the, shoulders74a, Mb-and 740. The extractor stems engage theejector hammers 56a,

j by breaking. Thisv brings the forward ends of thecocking rods 56b and 560 and .force them, back into position on the compression springs 68a, 686 and 680. The cams 65aJand 650, being rigidly connected with the corresponding ejector! hammer, are likewise moved back into position for release onsubsequent breaking of the gun. I

The gunmay belprovided with alock operating against a compression spring 90. The'handle of the'lock may be rigidly secured to a pin 91, as shown in Fig. 5, which isprovided atits base with an eccentric 7 7,

so arranged that upon turning, the plate 78 is, forced rea-rwardly, thus freeing the open ings 7 9 and 80, byreleasing the lugs Sland 82 as shown in Fig. 22, and freeing the gun for break-down. V 1 j I The gun is providedwith customary firing pins a and 800,,but it is preferred to provide a diagonal downwardly directed firing pin 80?) for the upper barrel, therebyv permitting the hammer 11?) to be somewhat shorter,

providing a more, compact and stronger mechanism. I r v The foregoing detailed description has been given for clearness of understanding only, and no unnecessary limitationsshould be'understood therefrom, but the appended. claims should be-construed' as broadly as per missible, in view of the prior art.
