BREECH-LOADING FIRE-ARM.

SPECIFICATION forming part of Letters Patent No. 328,005, dated October 13, 1885.

Application filed July 3l, 1884. Serial No. 139,242. (No model.)

To a/ZZ whom it may concern:

Be it known that I, HENRY F. CLARK, of Poughkeepsie, in the county of Dutchess and State of New York, have invented an Improvement in Breech-Loading Fire-Arms, of which the following is a speciiicat-ion. In this breech-loading nre-arm the triggerguard is pivoted at its forward end, and has a projection at its rear, which being pressed downward, the hammer is thrown back to half-cock, the firing-pin drawn back, and the locking-dog withdrawn. The further movement in the same direction opens the breech,

swinging it downward and forward, and then an extractor is brought into action to pull backand Veject theV shell, after which Yanother cartridge is to be inserted and the breech closed. The parts are very strong and simple, and the arm is not liable to become obstructed while in use. As the breech is closed the locking-dog is thrown back into its place in the housing, and the hammer insures the driving of such locking-dog entirely home in the act of cooking the hammer, so that the arm cannotnbe :tired-'until the breech is properly closed and secured.

In the drawings, Figure 1 is a section longitudinally of the fire-arm with the breech closed. Fig. 2 is a similar view with the breech open. Fig. 3 is an elevation of the front end of the breech-block detached. Fig. 4 is a rear view. Fig. 5 is a plan of the cartridge-support and the housing with the breech-block depressed. Fig. 6 is a cross-section of the barrel and stock, showing the sight and the manner in which it is held on the barrel; and' Fig. 7 is a plan of the pusher and linger that acts upon the hammer and firingpin, respectively.

The stock A is of ordinary character, and

the frame or housing B, into which is introduced .the breech-block, is made with its sides in line with the small of the stock and with a mortise through it. lThe stock is attached to the housing by the hollow screw-bolt a, introduced from the rear end of the stock and entering the metal of the housing at the rear, as seen in Figs. l and 2. This bolt is made tubular to obtain the required strength without being unnecessarily heavy.

The barrel D of the tire-arm is screwed at its rear end into the forward part of the housing, and below the barrel D there is a stud, d, the base of which passes into a dovetailed recess across the barrel. This stud d performs three duties: first, it receives the screw e, by which the wooden part E of the stock under the barrel is attached; second, this stud has a hole in it to receive the end of the wiping-rod F, and by means of which it is secured in place, such stud-hole having in it a screwthread for the reception of the threaded end of the wiping-rod; third, said stud d also receives and supports one end ofl the extractor'- spring hereinafter described. l Y

The breech-block G is pivoted to the housing B by the cross-pin g,which pinnalso forms the pivot for the forward end of the triggerguard, the dowel-pins 20 insuring the proper position of the two sides. The breech-block Gis made in two parts, that are secured together by the screws g2, and the joint for the trigger-guard comes between the two parts at their forward ends.

The pin g is slightly tapering. To hold the same when properly placed,I provide a groove or neck and a screw, 2, passing through one joint-eye of the breech-block into such groove. By loosening this screw the pivot-pin can be taken out.

The rear end of the breech-block is a segment of a circle from the center of the pivotpin g, in order that the breech-block may swing freely up to its proper place within the mortise through the housing. There is within the breech-block the locking-dog k, upon a pivot,

i, and the spring k acts to swing the locking-ff dog up into its place, so that it'may entera inor- I tise or recess in the housing when the breech is up in its place, and thereby hold thev breech and prevent the same opening by the recoil.

The back end of the locking-dog is nearly va lsegment of a circle, and the bottom of the recess for the same in the housing is similarly shaped, but both are slightly eccentric to the pivotv, so that the locking-dog acts as a cam and compensates for any wear which may take place on its face or in the recess provided for it in the housing. Should said dog fail to go entirely to place when the breech is closed, its movement is completed as follows: There is an arm, k, on the forward and lower part of the locking-dog, against which the rear end, 4, of the hammer M acts when the hammer is drawn back to full-cock, thereby completing the movement of the locking-dog and securely fastening the breech-block.

The hammer lll is between the two halves, forming the breech-block, and it is pivoted at m and provided with a mainspring` m. This spring m' is preferably extended at its lower end as the thin trigger-spring n. The trigger n is pivoted at 5, and is between the two halves of the breech-block, and upon the hammer are the half-cock notch 6 and the fullcock notch 7 for the end of the trigger or Sear. The ring-pin l passes through the breechblock and in line with the center of the barrel. Y

The trigger-guard'forms alever for opening the breech and for moving the firing-pin and hammer, the trigger-guard being pivoted at its forward end upon the pin g, which is also the pivot for the breech-block, the joint-piece of the triggerguard passing in between the two halves of the breech-block.

The spring o is fastened at its forward end within the breech-block, and its rear end acts upon a hook shaped projection upon the trigger-guard and holds the same in position.

At the rear end of this trigger-guard there is the retractor p, which passes up between the two halves of the breech-block and acts upon the locking-dog, so that asrrthe triggelgllard is pressed downwardly at its rear end the retractor p swings the locking-dog downward and forward out of the housing and relieving thebreech-block, so that thereafterthe breechblock andthe triggerguard c an movetogether as they swing upon the pivot g. The retractor p may be made in any desired manner, but I prefer to slot the locking-'dog vertically and centrally, as seen in Figs. 1, 2, and 4, so that the retractor may 'be in the form of a segmental arm correspondingto the curvature of the rear of the breech-block, and at ,the top of this arm there is an'L-shaped projection that acts above the locking-dog to swing it downwardly when the pivoted trigger-guard is depressed. The ret-ractor also has a lug or projection which comes in contact with a shoulder inside the breech-block after it has performed its ofce of drawing down and out the locking-dog, which prevents anyfurther mo-f tion of the -pivoted trigger-guard 'away from Y the breech-block.

` I here 'remark that usually the locking-dog will hold the parts when the gun is being `car-A ried from place to place; but to avoid risk of the-trigger-guard being swung away -from its positionrin handling the gun, 'I provide a slide-bolt, q, inthe housing, the forward end of which bolt passes into a hole at the -base of the reti-actor, to hold the same and the triggerguard -lever firmly in place. This bolt is moved back and fort-h by the hand acting upon the thumb-piece q2.

Above the pivot-bolt g the trigger-guard is provided with an arm, 1', having a forked upper end,and within the fork is aforked pusher, ff, and within the forked pusher 1" is a finger,

r2. 'Ihcs'e parts are all secured together by a pivot pin or screw. There is a limited extent of motion allowed to r and r2 upon the pivot, the respective parts being made with nearly flat bases that come in contact with the bottom of the fork in r, and prevent too great an extent of movement.

The hammer M at its forward edgeis notched for the recept-ion of the end of the pusher r', and one side of the firing-pin l is notched for the end of the finger r2 to pass into.

"When the pivoted trigger-guard is depressed by the pressure of the hand against its rear end, and the locking-dog relieved, the hammer is simultaneously brought to halfcock by the pusher 1" acting against the hammer and giving sufficient motion to drawback the hammer and cause the til-iggeifsear to enter thc half-cock notch 6. At the saine time the finger r2 draws back the firing-pin so that it is out of the way, andthe slot in the flringpin is longer than the width of the finger acting on the same, so that said firing-pin is unacted'upon by the nger when the breech is closed, and it is free to remain in the breechblock, and not to be driven forward by the closing ofthe breech and the pivoted trigger` guard.

At theside of the chamber in the barrel the cartridge back, as now usually employed; but I make use of a peculiar device for acting upon the extractor. rIhe extractor is at the end of an arm, t', having an eye, through which the pivot-pin g passes. Upon the joint of the pivoted trigger-guard, at the forward part thereof, vthere is a finger, a, projecting laterally in front of the eye'of the extractor, and the parts are so shaped that the finger u does not come into contact withv the arm ofthe extractor 'until the breech block is nearly opened, at which time the extractor and breech all swing together during the last part of the opening movement, .and the cartridge is' drawn back; and to give the extractor a sudden ICO movement to the rear, and throw out the loos- ,n

,ened and partially-extracted spent shell, I eniploy the spring M ',before named as projecting from the stud d. The end of this spring bears against the forward vpart of the extractors eye. l

In this eye isa notch,and the end of the spring sliding down the inclined upper surface of the notch givesthe extractor a sudden backward movement to eject the shell. Y

The shell need only be inserted far enough to clear'the end of the plate or guide u as it is pushed home by the breech-block in'closing. The firing-pin having been previously drawn back, there willbe n o danger of'pre'niaturev In order to support and guide the cartridge into the chamber of .the barrel, I make use of a swinging plate, 12, that is hinged at the rear end, at", c', to a plate that is screwed to the housing, and this plate is sufficiently narrow to swing down into the mortise in the housing into theposition shown in Fig. 2, and occupy Reafilryard 81. Downwm'd,

a position nearly in line with the bottom of the cartridge-chamber of the gun, so that the cartridge can rest upon the plate in being pushed into the gun or while the cartridge is being ejected. It is necessary to slot this plate u of a width and length sufficient to allow the hammer-head to rise up through such plate as the breech is closed. A slot in the hammer securely locks the plate when the gun is fired by its upper part passing over the crosspiece at end of the slot in the plate. Both ends of the slot in the plate o are rounded to allow the shell to slide freely in either direction. The plate o is pressed up by the act-ion of the breechblock as the latter is closed, but such plate is thrown down by aspring as the breech is opened. I extend the plate o to the rear as atail,v12,against which the spring presses. The upper part of the tail um, coming against the plate that is screwed to the housing, prevents the plate c from dropping farther than is required when the breech-block is thrown down; and I prefer to introduce a helical spring, r2, into a transverse hole in the back part of the housing, and to employ two studs, one at each end of such spring, the top one acting upwardly against the tail of the plate 1J and the other one downwardly against the top of the sliding bolt q, so as to apply to the latter sufficient friction to prevent the bolt moving by any concussion or agitation of the gun.

In order to apply the sight to this breechc loading gun I provide vertical channels-one By my improvement it will be seen that the' barrel may be easily wiped out from the breech, and the interior of the barrel can be examined from end to end at the rear. desired the hammer, may be shaped as shown by dotted lines in Fig. 2, so as to be more easily SO carried at support arms. The housing and stock are so nearly in line with the barrel that there is no risk of the parts springing when the gun is fired, thus insuring great Strength and accuracy in ring. The swinging breech-block and pivoted trigger-guard moving together, the momentum and Weight cause the extractor to act rapidly and powerfully to withdraw the shell and throw it out of the gun. The sight herein shown and described is not claimed by me in this application, as the same forms the subject of my application for patent led September l, 1884, Serial No.
