COCKIN Gr AND SAFETY MECHANISM FOR BREAKDOWN GUNS.

Specification of Letters Patent.

Patented Aug. 19,1913.

Application filed November 13, 1909. Serial No. 528,855.

T 0 all whom it may concern Be it known that I, EMIL FLUns, of Ithaca, in the county of Tompkins and State of New York, have invented a certain new and useful Cooking and Safety Mechanism for Breakdown Guns, of which the following is a specification.

My invention has for its object the production of a particularly simple and efficient break down gun mechanism; and it consists in the combinations and constructions hereinafter set forth and claimed.

In describing this invention, reference is had to the accompanying drawing in which like characters designate corresponding p arts in all the views.

Figures 1 and 2 are longitudinal sectional views of a portion of my gun, the same being shown as broken in Fig. 2. Fig. 3 is a longitudinal sectional view of the frame, illustrating particularly the safety mechanism. Fig. 4 is a plan of a port-ion of the trigger plate and contiguous part-s.

1 is the frame, 2 are the barrels pivoted at T 3 to the frame, and 4 is the fore-end of a break-down gun.

5, 6 and 7 are, respectively, the hammers, sears and triggers of the firing mechanisms of the gun, and 8 and 9 are, respectively, the

I main and sear springs.

7 usual catch 11 which cooperates with a rearwardlv-extending lug 12 on the barrels, and also a sliding bolt 13 movable in a horizontal guide extending lengthwise of the frame and into and out of a notch or recess 14 formed in the depending barrel lug 15, the bolt being suitably connected to a thumblever 10, and being here shown as formed with a slot 16, Fig. 4c, in which works an cccentric 17, Figs. 1 and 2, provided on the vertical spindle 18 upon which said thumblever is mounted. The bolt 13 is drawn rearwardly by the throwing of the thumblever and is moved into operative position by a spring 19 acting eccentrically upon the vertical spindle 18. The gun is also provided with means for holding the bolt 13 in its retracted or unlocked position, this means being automatically operable by the barrels to release the bolt as the barrels approach their normal or closed position. As here illustrated said means comprises a springpressed catch 20 movable in a vertical guide 21 formed in the frame 1 beneath the horizontal guide for the bolt 13, and opening into said horizontal guide. This catch 20 is movable by a spring 22 into the horizontal guide for the bolt 13, in front of a depending shoulder 23 on said bolt, and is provided with a part 24; projecting into the path of the barrel lug 15 in order to be engaged and depressed by said lug to move the upper end of the catch out of the path of the shoulder 23 for permitting the bolt 13 to be moved forwardly into the recess 14 of the barrel lug 15 by the spring 19, as said recess 14 moves into registration with the guide for the bolt 13. This catch 20, as here shown, is formed with a recess 25 opening through its lower end face, and in which the spring 22 extends, and also with an annular flange at its lower end, a portion of which flange projects into the path of the barrel lug 15 and forms the part 24.

The locking means shifts the safety mechanism of the gun into position to prevent the operation of the firing mechanisms, and as here illustrated the safety mechanism includes a longitudinally-movable member 26 arranged between the firing mechanisms and having laterallyextending shoulders 27 normally engaging upwardly-facing surfaces 28 on the triggers for preventing the operation of the triggers, the member 26 having its front end arranged in the path of the bolt 13 and its rear end engaged by a slide 29 arranged on the upper tang 30 of the frame. Said member 26 is supported by front and rear pairs of lugs 31 projecting upwardly from the trigger plate, the rear pair of lugs 31 engaging opposite sides of the member 26, and the front pair of lugs 31 forming pivotal supports for the triggers 7 and engaging the outer faces of said triggers, the inner faces of the triggers engaging opposite sides of the member 26. Both pairs of the lugs 31 are provided with pins 32 extending through slots 33 formed in said member 26, the pin 32 carried by the front pair of lugs 31 serving as the pivot for the triggers 7. The safety member 26 is also formed with angularlyarranged arms 34 and 35 extending upwardly at its front and rear ends, the front arm 34: projecting into the path of the rear end of the bolt 13, in order to be engaged and pushed rearwardly by the bolt, when said bolt is being shifted to un lock the barrels, the movement rearwardly of the member 26 carrying the shoulders 27 into engagement with the upwardly-facing surfaces 28 of the triggers 7 and thus locking said triggers. The rear arm 35 of the safety member 26 is engaged by a fork 36 provided on the slide or finger-piece 29 and consequently when the finger-piece 29 is moved forwardly, the fork 36 and the arm 35 move the safety member 26 forwardly to carry the shoulders 27 out of engagement with the upwardly-facin surfaces 28 of the triggers and into alinement with cutouts or slots 37 in the triggers and thereby release said triggers from the safety member. Obviously, when the gun is broken the triggers will be automatically locked from movement. The trigger-plate is detachably connected to the frame at 38 so that when the plate is detached the triggers and safety member will be removed therewith.

Usually in break-down guns the hammers are cooked by various forms of mechanism during the breaking of the gun, and in this gun the cocking mechanism comprises a member 39 arranged in an upwardly and forwardly inclined passage or guide 40 which is formed in a barrel lug 41 provided on the barrels in front of and spaced apart from the barrel lug 15, and extends lengthwise of the lug 41, said passage 40 opening through the front end of the lug 41 near the barrels and through the rear end of said lug at a point removed from the barrels. This cocking member 39 is provided at the lower portion of its rear end with a flattened shoulder 42 normally arranged under the front ends of forwardlyextending parts or arms 43 of the hammers 5 in order to lift said arms 43 and cock the hammers during the breaking of the gun. The front end 44 of the cocking member 39 is normally engaged by a rearwardly extending part or shoulder 45 provided on the fore-end 4 and opposed to the front end ofthe guide 40. Said cocking member 39 is of slightly greater length than the passage, or guide 40, and when the fore-end 4 is detached, the front end 44 of the member 39 projects slightly out of the passage 40 into position to be engaged by the shoulder 45 of the fore-end 4, so that when the fore-end is being attached to the gun, the shoulder 45 engages the front end 44 of the member 39, and moves said member lengthwise, thereby shifting the shoulder 42 into position to engage the forwardly-extending arms 43 of the hammers. "When the foreend 4 is removed, the cocking member is shifted forwardly by a spring 46, preferably located in a cavity or lengthwise passage 48 formed in the cocking member and terminating short of the front end of. the stem or body ofthe cooking member, the cavity or passage 48 opening longitudinally at 49 through a lengthwise side of the member 38. One end of the spring 46 abuts against the front end wall of the cavity and its other end engages an abutment or shoulder 47 which is fixed to the lug 41, is spaced apart from the closed end of the cavity 48, and projects into the cavity through the longitudinal slot 49 in said lengthwise side of the cocking member.

The locking means and safety mechanism of my break-down gun mechanism described ierein form the subject-matter of my pending divisional application Serial Number 685,086, filed MIarch 20, 1912.
