The object of this invention is to irovide an improved double barrel gun wl'iich may be operated as a repeater and either barrel lired repeatedly or the two barrels fired successively, and the iuvei tion also has for its object the provision of improved firing and cooking means. These stated objects, and other objects which will appear incidentally in the course of the following description,

1 are attained in such a mechanism as is illustrated in the accompanying drawings, and the invention resides in certain novel features which will he particularly pointed out in the appended claims.

In. the drawings:

Figure 1 is a side elevation of a gun embodying the present invention,

Fig. 2 is an enlarged longitudinal section,

Figs. 3 and l are longitudinal sections taken through side portions of the mechanism and showing respectively the means for locking the cylinder against rotation and the means for rotating the cylinder,

Fig. 5 is an enlarged transverse section on the line 5-5 of Fig. 1,

Fig. 6 is a transverse section on the line 6-6 of Fig. 4, and

Fig. 7 is a view similar to Fig. 6 but showing a modified arrangement.

In the drawings, there is shown a gun having a frame 1 and a stock 2 of the usual form and having two barrels 3 and l arranged preferably one above the otner, as shown, although they may be disposed side by side. be connected to the frame in any approved manner and the foreend 5 is provided upon the lower barrel in the usual position.

The front end portion of the frame provides a chamber 6 at the rear ends of the barrels and in this chamber is rotatably mounted a cylinder 7 having a plurality of bores 8 extending from end to end thereof and adapted to aline with the bores of the respective barrels. The cylinder may be of any desired'capacity but ordinarily will have four bores 8 and will be of such diameter that it will fit easily within the front end chamber of the frame. In practice, a cartridge will be placed in each of the bores 8 1929. Serial no. 382,200.

and the cylinder set so that two of e bores will be alined axially with the bores of the gun barrels. Then if it be desired to fire the barrels successively, the gun will be ready for such operation. If, however, it be de- 5 sired to fire one barrel repeatedly, the cylinder may be given a quarter turn after each shot so to bring a cartridge into position to be fired .throughthe selected barrel and this arrangement is very advantageous as it 60 is frequently desired to fire short range shots repeatedly before firing the long range shot and with the old style guns it was necessary to reload the active barrel'after each shot.

Generally, the cylinder will be pivotally mounted adjacent one side of the chamber 6, as shown in Fig. 6, so that two bores of the cylinder will be disposed laterally beyond the gun while the other two bores of the cylinder will be disposed centrally of the frame and alined with the gun barrels, and it is to be noted that one side of the chamber 6 is closed, as shown at 9 in Fig. 6, while the other side is open to accommodate the lateral 7 projecting portion of the cylinder. This arrangement provides an ample escape for the gases of explosion so that the marksman will not be affected thereby, the gases being directed toward the open side of the chamber and escaping freely therefrom. It may, however, sometimes be preferred to use the arrangement shown in Fig. 7 in which the frame of the gun is open at both sides, and the cylinder 10 is disposed with its axis midway the sides of the frame but alined with the material of the gun disposed between the two barrels, as shown at 11. This arrangement will cause the cylinder to project slightly from each side of the frame and is, therefore, more symmetrical than the first described arrangement and is adapted to guns in which the axes of the barrels are agreater distance apart than can be easily accommodated with the arrangement shown in Fig. 6. The several bores of the cylinder will be disposed so that no one bore will be wholly beyond the side of the frame and the active bores will be disposed vertically between the two inactive bores but otherwise an the operation will be the same as in the first described form.

The firing pins or plungers, shown at 12, are arranged to have their points 13 pass through openings provided therefor in the partition 14 which defines the rear wall of the chamber 6 so that they will be disposed in position to strike the primers of the cartridges 15 placed in the bores 8. The partition 14 is formed with sockets or tubular proj eotions 16 on its rear side receiving the heads 17 of the plungers and within the frame, spaced rearwardly from the partition, is a supporting plate or standard 18 through which the rear portions of the plungers slidably project, a spring 19 being coiled around each plunger between the head 17 and the plate 18 so that the plungers are normally held in their forward positions. The rear end of each plunger is formed to provide a. shoulder 20 and a beveled 'end 21 whereby it is adapted to be engaged and held by the cooperating sear and also on each plunger is a lug or offset 22 against which bears the rear end of abranch 23 of a forked block 24 slidably mounted in the plate 18, as shown; The front end of the block 24 is engaged by a finger 25 rising from the fulcrum 26 ofthe lever 27 which extends rearwardly below the frame and forms a guard for the triggers 28 in the usual manner, the opening in the block which receives the finger being large enough to accommodate the relative angular movement of the finger. Pivotallymounted within the frame at the rear of the plungers and alined with the respective plungers are sears 29 each of which has a locking head 30 at its front endto engagethe shoulder 20 of the coacting plunger or firing pin and each of which also has an arm 31 extending down.- wardly to rest upon the cooperating trigger 28. Springs 32 secured in the frame and bearing upon the respective sears hold them in engagement with the firing pins until relieved by the action of the triggers. A safety slide 33 is mounted in the top of the frame and bears upon-a projection 34 on each sear so that accidental firing of the'gun will be prevented. When the gun is to be cocked, the lever 27 is swung downwardly and forwardly thereby rocking the arm 25 so that the slide 24 is pushed rearwardly and, as the slide is in contact with projections on the plungers, the plungers will be moved rearwardly and the shoulders 20 thereof engaged with the respective sears and the plung ers held in retracted position against the tension of the respective springs 19. The leverwill be returned to its normal position illustrated in the drawings and the plungers will then be held in the cooked position, tlie slide block 24 being returned to normal with the lever. When the gun is to be fired, the

safety slide 33 is moved forward, whereupon,

if either trigger be'pulled, the correspond- 7 lug 38, as clearly shown of the lever 27 extends entirely across the boting -sear will be rocked to release its plunger which will thereupon be driven forcibly against the end of the alined cartridge by i the action of the expanding spring 19.

The frame houses means for locking the c linder 7 a ainst rotation said means con end 40of the bar is adapted to engage in one of the marginal notches 41 formed in the rear enn of the cylinder so thatnormally the cylinder' will be locked against movement, and it is held in such engagement byan expansion spring l2 coiled around the rear portion of the bar between a shoulder 43 thereon and th The fdlllll ln 25 tom of the frame and rocks with the lever. A crank 44 is fixed upon the fulcrum and rises therefrom to normally bear against the shoulder 45 on the lower edge of a' dog ii") which is pivoted at its front end to the side of the locking bar 37. The rear free end of the dog is arranged to restupon a stud l? on the .side of the lockin bar and a s rin 18 t: t: 7

upper cured upon said bar, bears upon the edge. of the dog, as. clearly shown in" Fig. ln Fig. 3, the parts are shown in the locked position. Vi/ hen the lever is swung downwardly and forwardly to cook the gun, the crank arm 44 hearing against the dog or latch l6 will r ck rearwardly and thereby retract the locking bar so that the cylinder will be free to turn. The crank arm is will, of course, swing downwardly as well as rearwardly and when its free end clears the shoulder 45, the locking bar will be free to return to its initial position under the influence of the spring 42. If the cylinder liasrlrcen turned the proper distance, the front end of the bar will a notch a1 but ordinarily the end of the locking bar w'll bear against the end of the cylinder and ride thereon until the proper movement thereof has been com pleted and a notch 41 brought into position to engaged. The forward movement of the locking bar will carry the dog to a position in advance of the position of the crank arm but when the crank arm returns to its normal position it will ride under the dog and lift the same against the action of the spring l8 so that the parts will resume the position shown in Fig. 3. l

7 At the opposite side of the frame, I provide means for rotating the. cylinder and this means is also operated by the lever 2?. Secured to the fulcrum 26 is a lifting arm which normally extends forwardly close to the bottom of the frame, as shown in'l ig. i. To the front end of this lifter is pivoted a link 51 which extends upwardly and is pivoted to the side of a lever 52 near the front end of the latter, the lever being fulcrumed at its Sal loo

lli'i rear end on the frame, generally at a point in the region of the safety slide. The front portion of the lever 52 is turned downwardly, as shown at 5-3, to obtain the proper movement and terminates in a hook 54 having one side closed by a web 55. Bivoted to the web 55 is a dog 56 which is adapted to a ratchet 57 fixed on the end of the cylinder concentric with the axis or" the same. A spring 58 is secured upon the edge of the lever 52 and bears against the dog 56 so as to hold the same normally in its operative position. illiam the lever moves upwardly, the dog 56 will impart movement to the cylinder through its enga 'eine t wits. a tooth or spur of the ratchet 57 out when the lever moves downwardly the dog will yield to the teeth of the ratchet and ride over the same without imparting any movement thereto. This movement of the dog is permitted by the spring 58 but movement of the dog away from the ratchet upon upward movement of the lever is prevented by the heel: 54, the inner surface of which follows the outline of the dog, as clear y shown in 4. When the lever 27 is drawn downwardly and forwardly to cool: tie gun, the loci-ring bar 3'? is 'etracted as has been described, and an upward movement is imparted to the lifting a m 50 at the same time. The upward movement of the arm 50 is transmitted through the link 51 to the lever and the airangement such that just as the locking bar 3'? withdraws from the cylinder the dog 56 will engage the ratchet and rotate the cylinder. It will thus be seen that by a single movement of the lever 27 from its initial posi ion and then back thereto, the gun is cocked, the cylinder released for rotation, and rotated so as to feed fresh cartridges into position to be lircd. This action also ellects reengageinent of the locking bar with the cylinder and return oi the feeding lever f2 and its associated parts to initial position. The gun is fired by rocking either trigger so that it will lift the corresponding sear from the plunger held by it so that the plunger will be projected to the cap of the cartridge which is to be fired.

From the foregoing description, taken in connection with the accompanying drawings, it will be seen that I have provided a very simple and compact mechanism whereby a gun may be operated easily and without exposing the user to danger. The cylinder may be mounted in a well known manner for swinging it out of alinement with the frame to facilitate loading, this particular mechanism not being a part of the present invention and, therefore, not being illustrated. The ordinary double barrel gun gives a choice of bores, having an open pattern for close shots and a choke pattern for distant shots, but no provision is made usually for firing more than two shots without having to reload. My present invention provides means whereby several shots may be fired without requiring reloading so that the gun also becomes a repeater. Vvhile the invention will be found applicable particularly to shot guns, it may also be applied to a combination rifle and shot gun.
