AUTOMATIC SINGLE-TRIGGER MECHA;NISM FOR DOUBLEBABREL GUNS.

Specification of Letters Patent.

Patented Sept. 1, 1914.

Application filed April 14, 1914. Serial No. 831,686.

To all whom it may concern:

Be it known that I, JOSEPH KAUTZKY, a citizen of the United States, residing at Fort Dodge, county of Webster, State of Iowa, have invented a new and useful Automatic Single-Trigger Mechanism for Double-Barrel Guns, of which the following is a specification.

My invention consists of novel means for preventing the immediate discharge of the second barrel after the discharge of the first barrel.

It further consists of novel means for actuating the trigger by the movement of the safety block, in order to insure the engagement of a portion of the trigger with said block.

It further consists of means for returning the block to unlocking position by movement of the trigger.

It further consists of other novel features of construction, all as will be hereinafter fully set forth.

For the purpose of illustrating my invention, I have shown in the accompanying drawings one form thereof which is at present preferred by me, since the same will give in practice satisfactory and reliable results, although it is to be understood that the various instrumentalities of which my invention consists can be variously arranged and organized, and that my invention is not limited to the precise arrangement and organization of these instrumentalities as herein shown and described.

Figure 1 represents a side elevation of the frame of a breech loading double-barrel gun, in detached position, and showing my invention carried thereby. Fig. 2 represents a sectional view on line w v Fig. 1. Fig. 3 represents a longitudinal vertical section of portions of the device, on line yy Fig. 2, in cocked position. Fig. 4. represents a longitudinal vertical section, showing portions of the device on line .e--2 Fig. 2, in fired position. Fig. 5 represents a vertical sectional view of certain of the parts seen in Fig. 1, showing the same in fired position, showing the block 22 wedged between the abutment 20 and the shoulder 21. Fig. 6 represents a vertical sectional view on line a-a, Fig. 1. Fig. 7 represents, in detached position, an elevation of the selective lever,

. and parts operable therewith. Fig. 8 represents a side elevation of portions of the device seen in Fig. 7, in a dlfierent position.

1 Similar numerals of reference indicate provided with means adapted for supportmg two barrels (not shown) at its front end portion.

4. designates hammers, which are pivotally mounted in the frame 1 in a suitable manner, and which are acted upon in any suitable or desired manner for moving the same to fired position, when released, each of said hammers having a scar notch 5 at a suitable point thereon.

: 6 and 7 designate the sears pivotally mounted with respect to the frame and said hammers, each being provided with a scar nose 8 adapted for engagement with the sear notch 5 of a hammer. Suitable springs 9 act upon said sears, tending to depress the same. Adjacent the end of each sear, opposite to that of the nose 8, is a lug or

arm

10 and 11 respectively, each lug being provided with a flat, inclined, lower face 12.

' 13 designates a'tumbler pivotally mounted, in the present instance, on the triggerplate, at a suitable point with respect to the lug ends of the sears, the-upper face of said tumbler being provided with the oppositely inclined faces 14. and 15, adapted and properly located for engagement with the faces 12 of the

lugs

10 and 11, and a roller 16 is journaled to the free lower end of the said tumbler 13.

17 designates a trigger pivotally mounted in any suitable or desired manner in the frame 1, and which, as here shown, is provided with a cam 18, which is adapted to engage with and be engaged by the said roller 16, by means of which contact, the tumbler 13 is turned into engagement with the

lugs

10 or 11, respectively, of the sears, when the trigger is pulled, as will be hereinafter described. The trigger 17 carries an upwardly projecting member 19, here shown as integral therewith, and on said member I provide an abutment or lug 20, which projects laterally sufficiently from the member 19 for the purpose hereinafter described.

21 designates a projection or shoulder carried by the said trigger.

22 designates the safety block, which is pivotally mounted in any suitable manner in operative relation to said trigger, at a point slightly to the rear and laterally of said member 19, said blockhaving a portion thereof suitably located and adapted for engagement with the projection or shoulder 21 of the trigger, this portion being shown, as a laterally extending lug 23,

having a face adapted to engage said shoul-' said block22 is seen in Figs. 2 and 3, out of the path of, and out of engagement with, the abutment 20 of the member 19. In the present. instance, I have shown the spring formed with two bearing members engaging.

the curved

upper faces

25 and 26 on said block, but any suitable means may be employed for accomplishing the desired action. I preferably form the upper face of the block curved, as at 27, for ease of operation of the parts.

In order to provide for which barrel,- that is, the right or leftshall be discharged first, I have mounted a selector attachment, consisting of a slide 28 movably mounted in the frame 1 and provided with a spring 29, extending rearwardly therefrom, and which is provided with an end which is preferably V-shaped, as at 30, and adapted for engagement with the underside of the tumbler 13, said slide 28 being adapted to be positioned by the operator, in order that the said end 30 .of the spring 29 will engage the said tumbler 13 on one side or the other of the pivotal point 31 thereof. As seen in Fig. 7, the said end 30 is in engagement on the underside of the tumbler 13, in front of the pivotal point 31, in order that the upper face 14 of said tumbler is in position to engage with the lug 10 of the sear 6. When the slide 28 is moved to its opposite position, that is, in the direction indicated by the arrow in Fig. 7, the end 30 of the spring 29 is moved to the other side of the pivotal point 31 of the tumbler 13, causing it to assume the position seen in Fig. 8, with its other face 15 in position to engage with the lug 11 of the other sear 7. At the same time, by this movement, the roller 16, carried by the tumbler 13, will be properly positioned with respect to the cam 18 of the trigger 17, in order to properly actuate the tumbler 13 to actuate the lug in engagement therewith.

The operation of the device will be readily understood. By opening the gun for loading, and returning the barrels to their proper position, the hammers 4 will be properly cocked; that is, they will be in the position seen in Fig. 1, with the sear noses 8 in engagement with the respective notches of the hammers 4:- The slide" 28 may now be moved to position the tumbler I3, dgpending j upon which barrel itis dcsiredto refirst. Considering that the same is in the position seen in Fig. 1, the parts will be in position to fire the right-hand barrel first, with the roller 16 on the left-hand side of the cam 18 of the trigger 17. By a rearward pull upon the trigger 17 it will be understood that the roller will be elevated, rotating the tumbler, upon its pivotal point 31, andelevating the lug 10 in engagement therewith, thus raising the end of the sear 6, releasing the hammer from engagement with the scar, and firing the right hand barrel. As the trigger moves rearwardly and the gun is fired, the force of the recoil will overcome the bearing of the spring 24 on the block 23, and will I rotate the block 22 upon its pivotal point, and position the upper surface 27 thereof beneath the abutment 20 on the member 19 of the trigger 17, and when pressure on the trigger is suddenly :eleased by the recoil, the abutment 20 engages the'said upper face of the block 22, see Fig. 5, said block being wedged between the abutment 20 and the shoulder 21. This engagement is only temporary, as the rebound of the gun from the shoulder of the operator will cause the trigger to engage his finger and be slightly raised, which will elevate the abutment 20, and the block 22 will be released from engagement therewith, and the shoulder 21 on the trigger in engagement with the lug 23 will overcome the holding action of the spring 24 and will rotate said block 22 on its pivotal point and it will return to normal or unlocking position ready for the next firing. In order to fire the second barrel, therefore, it is necessary for the operator to release the trigger, allowing the same to move downwardly, and the end of the right sear 6, which has been previously raised, is no.1 lowered by the action of the spring 9, with suitable force, to cause the lug 10 to strike the face 14 of the tumbler 13 and rotate the same on its pivotal point, thus moving it from its position inFig. 1, to that seen in Fig. 3, causing the roller 16 to be moved to the opposite side of the cam 18,-

It will thus be seen from the above,'that I have provided a safety device, which is mounted upon the frame independently-of the trigger and normally out of engagement therewith, but which is adapted to be abtu: ated by the recoil to be moved'in the path of, and to engage with, a suitable portion of". I

the trigger to prevent the involuntary or premature firing of the second barrel, after the-first barrel has been discharged, and this action is assisted by the movement of the vised anovel and useful construction of an automatic single-trigger mechanism for .double-barrel guns, which embodies the features of advantage enumerated as desirable in the statement of the invention and the above description, and while I have in the present instance, shown and described a preferred 1 embodiment thereof which will give in practice satisfactory and reliable results, it is to be understood that the same is susceptible of modification in various particulars without departing from the spirit or scope of the invention or sacrificing any of its advantages.
