BRI-:Ecl-l-LOAVDINo GUN.,`

SPECIFICATION forming part of Letters Patent No. 418,951, dated January '7, 1890.

Application tiled July 27,1889. Serial No. 318,884. (No model.)

To all whom it may concern:

Be it known that I, JAMES JENSEN, of Park 4 Place, in the county of Lee and State of Arkansas, have invented a new and Improved Breechv-Loading Gun, of which the following is a full, clear, and exact description.

This invention relates to breech-loading guns, the main objects of the invention being to provide for the secure locking of the gunbarrels when such barrels are moved to the firing position, to provide for the holdin g back of the retaining-bolt after such bolthas been withdrawn to release the barrels, and to improve the action of the extractor.

To the ends named the invention consists, essentially, of a barrel formed with a projection, a bolt arranged to engage said projection,a spring arranged in connection with the bolt, a catch by which the bolt is held in the retracted position, a slide, a catch arranged in connection therewith, a thumbpiece arranged in connection with the catch and carried by the slide, and a lever that is connected to the slide and to the bolt, all as will be hereinafter more fully described, and

specifically pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar gures and letters of reference indicate corresponding parts in all the views. y

Figure 1 is acentral sectional view of my improved breech-loading gun, the parts being represented as they appear when the barrels are in the firing position. Eig. 2 is a similar view, the parts, however, being represented as they appear when the barrel has been movedto the extracting and loading position, Figs. 1 and 2 being taken on line 1 1 of Fig. 3; and Fig. 3 is a view of the butt-end of the barrel, representing the same as it appears when removed from the stock.

In the drawings, 10 represents the actionframe and 11 the barrels. Vithin the frame 10, I mount a lever 12, the lower end of said lever being pivotally connected to a lockingbolt 13, which is normally held in the position in which it is shown in Fig. 1 by a spiral spring 14, said spring being coiled about a rearwardly-extending stem 15,-t-hat is made integral with or rigidly connected to the bolt 13, the spring abutting against a stop 16,

and against a shoulder 17, formed upon the boli. The upper end of the lever 12 is pivotally connected to a slide 20, to which there is secured abracket 21, said bracket being arranged upon the outside of the frame and being connected to the slide by means of a downwardly-extending projection 22.

To the slide 2O tl1ere is pivotally connected a catch 24, which is normally held in the position in which it is shown in Eig. 1 by a spring 25, and just above the rear end of the catch 24, I mount a thumb-piece 26, said thumb-piece being supported within a slot formed in the bracket 21, and being formed with a downwardly-extending spur 27, which bears against the upper face of the catch 24., and with a milled or serrated face 28, against which the thumb of the operator is placed.

Beneath the bolt 13, I arrange a catch-sprin g 30, the purpose of which will be hereinafter explained. The gun-barrels 11 are formed with a downwardly-extending and recessed projection 3l, in which there is mounted a bell-crank lever 32, one arm of said lever exi en ding` to the rear, while the other arm enters a slot 33, that is formed in the mainI stem 34. of the extractor 35, the extractor being guided by an auxiliary stem 36, which rides in aproper aperture formed in the filling between the barrels. We will suppose the parts to be in the position in which they are shown in Fig. 1. Then, itthe thumb-piece 26 be moved in the direction of the arrow shown in connection therewith, the projection 27 will be carried downward and will act to throw the catch 24 from engagement with a shoulder b, that is formed upon the frame 10, any continued pressure upon the thu mb-piece acting to move the slide 2O toward the barrels, and as the slide so moves the lever 12 will be rocked, as indicated by the arrow shown in Fig. 1, and the bolt 13 will be moved backward out of engagement with the barrel projection 31, the bolt being caught by the spring-catch 30 after it has been thrown fully inward, and the parts being held in the position in which they are shown in Fig. 2.l After the bolt has been withdrawn the barrels may be tilted as indicated, and as they are so tilted the projection c of the lever 32 will bear against the frame-shoulder d and the lever will be rocked, and in rocking will IOO force the extractor outward to the position in which it is shown in Fig. 2. In returning the barrels to their normal positions the shoulder e, formed on the barrel projection 31, will strike against the upwardly-extending section of the catch-spring and Will force said spring downward, thus permitting the spring 14 to act to draw the bolt 13 forward and into engagement with the rearwardly-extending section of the projection 3l.

By means of the construction above described I obtain a perfectly secure locking of the barrels in the tiring position, and I provide for the easy closing of the barrels after they have been moved to the loading position, inasmuch as I am not required to force the bolt 13 back against the tension of its spring 14. Havingthus described my invention, I claim as'new and desire to secure by Letters Patentl. In a breech-loading gun, the combination, with a barrel formed with a rearwardlyextending projection, and a spring-actuated bolt for engaging the said projection, of a slide, a pivoted lever having one end connected to the bolt and its other end to the slide, and a spring-actuated catch carried by the slide and locking it against forward move-A ment, substantially as described.

2. In a breech-loading gun, the combina- 3. In a breech-loading gun, the combinal tion, with a locking-bolt and its spring, of a lever pivotally connected to the bolt, a slide connected to the lever, a spring-actuated catch carried by the slide, a bracket connected to the slide, and a thumb-piece connected to the bracket and formed with a pro! jection Which bears upon the catch, substantially as described, Y

4. In a breech-loading gun, the combination, with the barrels, of a bell-crank lever 32, an extractor formed with a main stein that is engaged by one arm of the said lever, and a frame projection against which the other arm of the lever bears when the barrel is tilted, substantially as described.
