i Application filed January 6, 1914. Serial No. 810,648.

pivotal engagement above referred to, is mounted a cooking lever 73, the forward arm 70 of which is in constant engagement with the barrel 9 and the tail 70 of which rests under and cooperates with the nose Z of a lever Z which is also pivoted within the frame I), as at Z and which has formed integral therewith an arm Z which is adapted to move in an inclined groove 0 formed in the lower front side of the hammer 0. When the barrel 9 is rocked about the pivot pin 2' the tail 72 of the'lever 7c is moved upwardly into engagement with the underside of the To all whom it may cone-em Be it known that I, Gnonor. S. Lewis, a citizen of the United States, residing in the city of Springfield, county of l-lampden, State of Massachusetts, have invented certain new and useful Improvements in Firearms, of which the following is a specification, reference being had to the accompanying drawings, forming a part hereof.

This invention relates particularly to single shot breech loading firearms of low cost and has for one of its objects the provision of such a gun with simple, effective and inexpensive means to control the extractor and move the hammer to cocked position.

A further object is to provide in combination with a locking bolt of suitable form an improved safety latch operable thereby when the gun is broken so as to prevent the subsequent firing of the piece until the said latch is moved manually to'inoperative position. i

Still another object of the invention is to mount the extractor directly within the wall of the barrel and the cooperating release mechanism for the extractor entirely within the frame of the gun thereby greatly simplifying the construction and expediting the downwardly the arm Z and forcing the ham- Ther 0 into its cooked position, as illustrated in Fig. 3. On the tail 76 of the cocking lever 70 is pivoted a hook m, as at m, which cooperates with a shoulder a formed on the underside of the extractor n which is slidably mounted in the lower wall of the barrel g and is pressed outwardly by a suitable spiral spring 0. ment of the extractor n is limited by means of a suitable transverse stud p which is engaged by a second shoulder 11. formed in the extractor. So long as the gun is closed, as shown in Fig. 2, the extractor a is held in operativeposition against the pressure of the spring 0 by reason of its abutment with the solid front wall 7) of the frame I) and at this time the extractor hook we need not be in direct engagement with the shoulder a in the extractor. As the gun is broken, the hook m is forced into engagement with the shoulder at by a suitable wire spring 712 carried on the cooking lever 70 and engaging a stud m which passes transversely through the ejector hook m and projects on each side thereof for a reason which will presently appear. This engagement of the hook m with the extractor a is maintained until the shell is to be started rearwardly out of the barrel 9 and at this instant, the stud m is moved against suitable ledges or shoulders 12 formed on the inner side walls of the frame Z2, whereby further travel'of the nose of the hook on upwardly under the influence of the tail lc of the cooking lever 70 is prevented and the hook is tripped so as to release the extractor and permit the spring 0 'to operate the same.

By the mechanism described it will be evident that only the extractor is mounted with the barrel g and that when the Reference is now to be had to theaccompanying drawings for a detailed descrip- Figure l is a side view of a gun embodying the present invention. Fig. 2 is a fragmentary detail'view, partlyin sect-ion andpartly in side elevation and .on a much. larger scale, of a gun provided with the invention, the barrel and frame being locked Fig. 3 is a view substantially similar to Fig. 2 showing the relationship of the parts after the gun has been broken. Fig. 4: is a view in section taken on the plane indicated by the line H ofvFig. 2 and looking. inthe direction of the arrows.

.In the rifle shown inthe drawings the stock a has secured thereto as usual the frame I), which is of ordinaryconstruction, and has pivoted therein thehammer 0 acted upon by a coiled main springd and controlled by a spring pressed sear e and trigger f. Adjacent the forward end of the frame I) is mounted pivotally the barrel 9 which may be locked to the frame in the usual manner by the fore-end h. Upon the transverse pivot pin iwhich is carried by the frame I) and engaged by the barrel 9 to form the nose Z of the lever Z, thereby throwing The ejecting movelbarrel is detached from the frame of V the gun the release mechanism for the extractor remains in position within the frame. It also appears that no holder for the barrel is employed in the improved mechanism and the release of the extractor is brought about directly by the engagement of the barrel 9 with the cooking lever 7c. Indeed, the fore-end it has no function in the improved gun save that of main taining the barrel in locked engagement with the frame and so far as the operative devices of the gun mechanism proper are concerned, this fore-end might be omitted entirely.

Another feature of importance included in the present invention has to do with the locking bolt and safety latch and while these features are shown in combination with the extractor mechanism above described, it will be evident that they will be useful independently thereof. The locking bolt 9 cooperates with a suitable depending lug carried by the barrel 9 in substantially the usual manner to hold the barrel in fixed relationship with the frame I). The bolt 1 is connected through links 9 to the top lever 7 by which the bolt may be retracted to permit the gun to be broken. Within the frame I) is pivotally' mounted a safety latch s which is secured to a finger piece 8 through a link 8 the finger piece being slid manually in substantially the usual way to swing the safety latch into and out of operative position with respect to the trigger On the trigger f is carrieda pin f with which cooperates the lower end of the safety latch s to prevent movement of the trigger f about its own pivot when the finger piece 81 is in safety position. IVhen the finger piece 8 is slid to swing the safety latch s away from the dent that the trigger f may be operated to release the hammer. On the front edge of the safety latch s is formed an arm 8 which is disposed within the path of the locking bolt 9 so that when the gun is broken and the bolt moved rearwardly, the safety latch will be swung to operative position to pre vent the piece from being fired. until the finger piece is again operated manually as above described. It will be observed that this action is entirely automatic and since it ensues whenever the gun is broken, it insures absolute safety after the insertion of a cartridge until the safety latch is actuated.

Modifications in the construction. of the invention illustrated will suggest themselves to those skilled in the art, but all such changes are to be deemed within the scope of this invention.

I claim as my invention:

1. In a firearm, the combination of a barpin f, it will be evirel, a frame, a pin carried by the frame and adapted to engage the barrel to unite the frame and the barrel hingedly, a hammer mounted in the frame and a cocking lever mounted on said pin and having oppositely extending arms, one of which engages directly with the barrel, an independent lever operatively disposed with respect to the hammer and with which the other of said arms engage, whereby the hammer is cooked when the firearm is broken and a locking bolt with which the said last named lever cooperates when the firearm is broken.

2. In a firearm, the combination of an extractor, a spring to actuate the same, a cocking lever, means carried on the cocking lever to hold the extractor in retracted position and means cooperating with the last named means to actuate the same at a predetermined time and release the extractor.
