Specification of Letters Patent.

Patented Oct. 17, 1905.

Application filed February 9,1905. Serial No. 244,862.

To LM 'Lu/wm, it' 71u57/ concern:

Be it known that I, ANsLEY H. Fox, of the city and county of Philadelphia, State of Pennsylvania, have invented an Improvement in Breech-Loading Breakdown Guns, of which the following is a specification.

My invention has reference to breech-loading breakdown guns; and it consists of certain improvements which are fully set forth in the following specification and shown in the accompanying drawings, which form a part thereof.

My invention comprehends certain improvements in that class of firearms known as breech-loadingbreakdown guns and embodies an improved construction and means for operating the hammers and sears which simplify and facilitate manufacture and accomplish other desired results, as hereinafter more fully set forth.

In the accompanying drawings, Figure l is a longitudinal sectional view ofthe breech portion of a gun embodying' my invention and illnstratingthe parts as they appear with the barrels broken down for loading and the locks cocked. Fig. 2 is an inverted plan view of the breech-frame and other parts. Fig. 3 isa sectional elevation on line 3 3 of Fig. 2, showing the means for settling the hammers; and Fig. 4 is a cross-section of same on line 4 4 of Fig. 3.

The barrels A are hinged to the breechframe B in the usual manner and are provided with a bottom lug A, dependent from the under side of the barrels, which lug is preferably integral therewith. In this lug I place a cooking-plate C, which serves to engage with and lift the hammers D by their forward-extending arms D as the barrels drop for loading. The rear end of this cocking-plate forms a lug which rests normally below the extended arms of the hammers to move them, and said plate is secured to the barrel-lug by means of a T-shaped extension O, guided in a T-slot O2, which extends longitudinally almost the entire length of the said barrel-lug A.

On top of the cooking-plate there is a small stud, against which a spiral spring' S is applied and held in place byascrew-plug S, so that as soon as the fore-end iron R, which serves as an abutment for the front end of the said cooking plate or slide, is removed the spring will force the cocking-plate rearwardly and out of engagement with the hammer ends, thereby allowing the barrels to be readily attached or detached from the frame.

The hammers D are provided with the forwardly-extending arms D,which are brought laterally inward, so that their forward ends lie normally in the barrel-lug slot P in the center of the breech-frame, while their lrear ends continue back at substantially right angles and serve to strike the primers.

The hammer-arms D are turned laterally inward at a point just forward of the pin D2, on which they are pivoted, and directly under and in front of the pivot-pin they are slotted to receive a toggle E, which serves to actuate a round plug or follower F for the purpose of compressing the spiral mainsprings G as the hammers are cocked. These springs are inclosed in parallel tubular apertures H', arranged in the forward part of the breechframe and respectively upon opposite sides of the slot P for the bottom lug of the barrels. They are in direct line with the striking parts of the hammers, whereas the forward arms D of said hammers are oppositely cranked, so as to come close togetherin the slot between the said springs Gr. The particular angular shape of the hammers is, moreover, important, as it enables the forward arms D extending around that portion B of the breech-frame in which the locking mechanism for the barrels is located. Said locking mechanism is operated by the rock-shaft W and4 lever W.

The hammers D are held in the cocked position by the engagement of the sears H in the manner shown, and the sears are kept up to their work by the Sear-spring I, which consists of one flat piece of steel with two spring-arms I I extending rearwardly and resting, respectively, upon each of the sears.

The scar-spring is held in normal position by one screw Q1, which draws it down to the breech-frame, and thereby puts a tension upon both the sears H as the screw is screwed into place.

J represents the triggers, which have shoulders for tripping the sears H to release the hammers. These triggers are pivoted at K and have upwardly-extending arms J at the rear of their pivoted points. Arranged in the Lipper part of the frame is a slide L, having a lug M extending downward and adapted to be moved over the arms J of the triggers IOO to lock them against movement to release the hammers. rI`he slide L has an extension terminating in a thumb piece L above the breech-frame and by which it may be shifted longitudinally into and out of locking position. To retain the slide L in either of its eXtreme positions, I make its rear end inthe form of a spring N, with a head which is adapted to snap into either of the depressions O. Any other means of retaining may be employed in lieu of that shown.

It is obvious that numerous modifications of my invention may be made without departing from the essential points.

. That I claim as new, and desire to secure by Letters Patent, is-

l. In a hammerless gun of the class described, the combination of two barrels having a barrel-lock provided with a cocking-lug,

and a breech-frame having a central opening close to and in line with the barrel-lug and to which breech-frame the barrels are pivoted in advance of the barrel-lug, two hammers pivoted to the breech-frame and having their forward ends turned laterally inward to a central position adjacent to the cooking-lug so that they work close together side by side in a central opening in the breech-frame, toggles hinged to the hammers to each side of their forward lateral ends, and spiral springs for operating the hammers through the tog-l gles arranged upon opposite sides to the cocking-lug and central openingl in the breechframe and forward lateral arms of the hammer. Y

2. The combination of the breech-frame, pivoted barrels having' a cooking-lug, a springactuated cooking-plate, two pivoted hammers having their forward ends turned laterally inward so as to work close together in a central position back of the barrel-lug, toggles carried by each of the hammers, spiral springs within the breech-frame on opposite sides of the barrel-lug and the forward ends of the hammers for operating the hammers through the toggles, and a fore-end iron having its under part extending forward to directly press against the cooking-plate and act as an abutment to hold it in operative position against the action of its spring.

3. rIhe combination of a breech-frame havingacentral opening, two pivoted barrels having a cocking-lug arranged to be received in the forward end of the central opening of the breech-frame, two hammers having the forward ends turned laterally toward each other so as to work close together in the central opening' in the breech-frame in line with the barrel-lug, spiral springs within the breechframe on opposite sides of the barrel-lug and forward ends of the hammers for operating the hammers, and a cocking-lug carried by the barrel-lug to engage the forward arms of the hammers.

4. The combination of the hammers, two pivoted sears for controlling the hammers, triggers for operating the sears, and a searspring consisting of one piece having a body secured to the breech-frame between thehammers in advance of the pivots of the sears and having two rearwardly-extending spring-arms pressing upon the sears to the rear of the pivots.

5. In a hammerless gun, the combination of a breech-frame having a central opening in the rear of the pivots of the barrels with the breech-frame, two spring-actuated hammers provided with laterally arranged forward arms and in which the arms of the respective hammers extend laterally in opposite directions so as to come close together and occupy the central opening in the breech-frame, a cooking-lug movable with the barrels and engaging the forward ends of the arms of the hammers and also working through said central opening whereby the hammers are moved to cocked position when the barrels are broken down, and spring devices for operating the hammers located upon each side of the central opening in the breech-frame.

6. In a hammerless gun, the combination of a breech-frame having a central opening in the rear of the pivots of the barrels with the breech-frame, two spring-actuated hammers provided with laterally arranged forward arms and in which the arms of the respective hammers extend laterally in opposite directions so as to come close together and occupying the central opening in the breech-frame, a sliding plate forming a cocking-lug and carried with the barrel-lug for engaging the forward ends of the arms of the hammers whereby the hammers are moved to cooking position when the barrels are broken down, a spring to move the cooking-plate out of engagement with the hammer-arms, and a foreend iron directly acting upon the cockingplate itself for holding' it in operative position against the spring in the assembled condition of the gun.

7. Inahammerless gun, the combination of the breech-frame, two hammers, pivoted barrels, a lock for the barrels, a spindle to operate the lock at the rear of the breech-frame, two sears for the hammers, triggers for operating the sears, and a V-shaped scar-spring having the two arms rearwardly extended to straddle the locking operatingspindle and pressing upon the sears and the intermediate portion screwed down to the breech-frame intermediate of the hammers.

In testimony of which inventionI hereunto set my hand.
