GUSTAF ELLSTROM, OF FITGHBURG, MASSACHUSETTS, ASSIGNOR TO MARY E. JOHNSON, OF FITCHBURG, MASSACHUSETTS, EXEOUTRIX OF IVER JOHNSON, DEOEASED.

BREECH-LOADING FIREARNI.

Specicaton of Letters Patent.

Patented Oct. 24, 1905.

To a/ZZ whom t may concern:

Be it known that I, GUSTAE ELLsTRoM, a citizen of the United States, residing at Fitchburg, in the county of Worcester and State of Massachusetts, have invented a new and useful Breech-Loading Firearm, of which the following is a specification.

the firing of the gun when the same has been cocked are both controlled by the triggernger of the user without change of position.

Further objects of this invention are to provide a novel form of breech-locking mechanism and to improve the special constructions and combinations of parts. l

To these ends this invention consists of the breech-loading firearm and of the combinations of parts therein,as hereinafter described, and more particularly pointed out in the claims at the end of this specification.

In the accompanying two sheets of drawings, Figure l is a side View, partly broken away, of sufhcient parts of a gun to illustrate the application of this invention thereto. Figs. 2 to 4, inclusive. are similar views showing the parts in different relative positions, Fig. 2 showing the gun cocked, Fig. 3 showing the position of the. parts'holding the breech-locking mechanism from opening when the gun is red, and Fig. et showing the position of the parts when the breech-locking mechanism is released. Fig. 5 is an enlarged view of the hammer and parts coperating therewith. Fig. 6 is a front view of the same. Fig. 7 shows a front and side view ofthe trigger controlling the barrellocking mechanism. Fig. 8 shows a front and side view of the firing-trigger. Fig. 9 is adetail view of the releasing-lever and its spring. Fig. l0 is a detail view of the stop for preventing the unlocking of the breech during the iiringlof the y gun, and Fig. 11 is a detail view of the barrellocking bolt.

In that class of firearms to which this invention relates it has heretofore been customary to employ abarrel-catch which is controlled from a finger-piece or trigger and a iiring mechanism which is controlled by a second fingerpiece or trigger. In the constructions heretofore employed the linger-piece or trigger for opening the gun has been located ata distance from the firing-trigger. In order to open such a gun, it has heretofore been necessary for the user to shift the trigger-finger from the firing position to engage the unlocking finger-piece or trigger. One construction of such a gun is illustrated in United States Letters Patent No.'697,516, granted April l5, 1902. in the name of Oscar F. Mossberg. The especial object of this invention is to improve and perfect this form of gun by providing a construction which will enable the user to open the gun without moving the trigger-finger from firing position. To accomplish this object, I have provided a gun having the firing-trigger and an opening finger-piece or trigger.' as in the Mossberg patent'before referred to, except that said triggers are arranged adjacent to each other,

(preferably being pivoted upon the same pin,) so that both triggers are controlled by the trigger-finger of the user when in firing position and by providing a stop for preventing the releasing-trigger from being operated when the gun is fired.

Referring to the accompanying drawings and in detail, a gun embodying this invention as herein illustrated comprises a frame F. Pivotally mounted on a pin f in the frame F is the` barrel B. A hammer H is pivoted in the frame and is operated by a hammer-spring t. These parts may be of the usual or ordinary construction and need not be herein described at length.

In order to fasten the barrel in closed or operative position, I preferably employ a locking-bolt which is located in the barrel-lug and IOO ' of the hammer.

the usual lug or bottom rib L, and mounted in the lug L is a locking-bolt 10. As shown most clearly in Fig. 11, the locking-bolt 10 is preferably made in the form of an angular frame and is normally forced back by means of a spring 12. rI`he locking-bolt 10 is held in place and its movement is limited by means of a pin 11. To release the locking-bolt and to permit the barrel to open, I provide a releasing-lever 32, which is mounted upon a pin 13 in the frame.

As shown most clearly in Fig. 9, the releasing-lever 32 is provided with a slot or recess for receiving a spring 14. Cooperating with the releasing-lever 32 is a trigger 16, which is mounted upon a pin 15, which trigger 16 engages behind the releasing-lever 32, so that when said trigger is pulled the barrelloeling bolt will be released and the barrel permitted to open. Arranged adjacent to the unlocking-trigger 16, but entirely independ ent in action therefrom, is a firing-trigger 18. In practice the firing-trigger is preferably housed within a slot in the unlocking-trigger and is pivoted upon the same pin 15 as the unlocking-trigger.

As shown most clearly inFigs. 7 and 8, the firing-trigger 18 is mounted in a slot or recess 17 of the releasing-trigger 16, and the tiring-trigger is normally forced back by a small trigger-spring 19, housed within the releasing-trigger 16. At its upper end the liring-trigger 18 is intended to engage the notches or teeth of the hammer H.

Then the parts are in normal position, as shown in Fig 1, thefiring-trigger engages the front notch of the hammer to hold the hammer in its rebounded or normal position. When the gun is cocked, as shown in Fig. 2, the firing-trigger 18 engages the other notch Then the firing-trigger is pulled to tire the gun, in order to prevent a simultaneous operation of the unlocking-trigger I have provided a stop which will pre vent an unlocking operation of the barrel eX- cept at a time when the gun is not cocked.

As shown, the hammer H is provided with an operating arm or cam 21, which is arranged to depress a spring-pressed stop 20 when the gun is cocked. At its forward end the springpressed stop 2O is provided with a notch 22, as shown in Fig. 10.

The firing-trigger is provided on its rear side with a projection 23, coperating with the notch 22 of the stop 20, and when the stop 20 is held down, either by reason of the gun being cocked or by reason of the projection 23 of the firing-trigger having been moved back into engagement with the notch 22, the stop 2O will be located in position to be engaged by abutments 241i on the releasing-trigger, so that said stop will prevent the releasing-trigger from being operated to unlock the gun until after the pressure upon the firing-trigger has been released and the parts have been allowed to again assume the normal position illustrated in Fig. 1. By means of this construction I have provided a gun having separate triggers for firing and for opening the gun, but have arranged the parts so that the gun can be opened or fired without shifting the trigger from firing position.

I am aware that numerous changes may be made in the construction of guns without departing from the scope of this invention as expressed in the claims. I do not wish, therefore, to be limited to the construction I have herein shown and described; but

What I do claim, and desire to secure by Letters Patent of the United States, isM

1. In a breech-loading firearm, the combination of a barrel-locking mechanism, a firing mechanism, a trigger for the barrel-locking mechanism and a firing-trigger, said triggers being concentrically pivoted, so that said triggers are in position to both be engaged by the trigger-finger of the user.

2. In a breech-loading firearm, the combination of a barrel-locking mechanism, a trigger for releasing the barrel-locking mechanism, a ring mechanism, a tiring-trigger, said trig gers being pivoted concentrically, so that both may be engaged by the trigger-linger of the user, and a stop for preventing the opening of the gun While the same is cocked.

8. Ina breech-loadingiirearm, the combination of a gun-frame, a barrel pivotally mounted therein, a locking-bolt mounted in and movable with the barrel, a releasing-lever pivotally mounted in the frame, anda trigger for operating the lever to release the lockingbolt.

4. In abreech-loading firearm, the combina tion of a gun-frame, a barrel pivoted thereto and having a downwardly-extending lug, a locking-bolt having the form of a frame with sides and an end piece, said locking-bolt bcing mounted in the barrel-lug, a releasing lever mounted in the frame, and a trigger for operating the releasing-lever to release the locking-bolt.

5. Inabreech-loading firearm, the combination of the frame, the barrel pivoted thereto, a locking-bolt mounted in the barrel-lug and movable therewith, a releasing-lever mounted in the frame in position to engage the locking-bolt, a firing mechanism, a trigger for the firing mechanism, and a trigger for the releasing-lever, said triggers being' adjacent to each other in position to both be engaged by the trigger-finger of the user.
