BREECH-LOADING FIRE-ARM.

SPECIFICATION forming part of Letters Patent No. 312,564, dated February 1'7, 1885.

Application filed Angust lfi, 1884. (No model.)

closing the breech, and has also reference to the class termed hammerless guns.

The invention consists in novel devices for automatically cocking the hammer with the' operation of opening the breech in loading the barrel, all as hereinafter more fully described, and specifically set forth in the claim.

In the annexed drawings, Figure 1 is a side view of the breech-block and parts adjacent thereto with the lock-plate removed to better Fig. 2 is alon- Fig. 3 is a top illustrate our improvements.

Fig.6 isa longitudinal section illustrating the connection of the fore end with the barrels. Fig. 7 is an inverted plan view of the connection of the breech-bolt with the post, which is pivoted in the breech-block and operated by a lever affixed to said post on top of the breech-block; and Fig. Sillustrates modifications of the device for automatically cocking the hammer.

. Similar letters of reference indicate corresponding parts.

- Adenotes thebreech-block, formed with the usual breech-extension, A, to the end of which the barrels B B are hinged in the usual and well-known manner. The breech-extension is formed with the usual longitudinal mortise,E, and to the under side of the barrels is afiixed a lug, L, which enters the mortise E when the barrels are thrown into their closed position, as shown in Fig.2 of the drawings. The breechbolt m, entering a notch in the rear end of the lug L in the usual manner, and operated as hereinafter described, serves to hold the barrels in their closed position. The under side of the barrels we provide with a rigid hook,

check-pin G, and the other arm of said lever" is connected with the end of a tumbler, b,which is pivoted between its ends on the lock-frame, as shown in Fig. 1 of the drawings. The opposite end of the tumbler engages with the under side of a cam, 0, on the heel of the hammer H, which latter is arranged inside of the lock-case and concealed from the exterior of the gun. I

01 represents a spring, which presses on top of the cam cto impart to'the hammer the requisite force for striking the firing-pin. The resistance of said spring being transmittedto the check-pin G, greatly relieves the latter of the jar incident to its arrest of the tilting movement of the barrels when throwing the same.

into an open position, as shown by dotted lines in Fig. 1 of the drawings.

We do not confine ourselves strictly to the arrangement of the lever a,'tumbler b, and cam c, as aforesaid, inasmuch as the same or a similar effect can be produced by other though analogous means, as shown, for instance, in Fig. 8 of the drawings,wherein the lever a is bell-crank shaped, and the motion is transmitted from said lever to the hammer by means of an arm or push-bar, b, pressing against a cam, which projects upward from the pivoted portion of the hammer.

The salient feature of the described devices is the employment of the extra check-pin held yieldingly in its position back of the hinge-- mer is thrown to a cocked position, as shown the described stop.

charge of the gun, we employa safety-stop, 0,

in the form of an arm pivoted below the tang D, and having its lower end adapted to engage directly with the trigger and its upper end extended through a slot in the tang and provided above the same with a thumb-piece or manipulating head, h, which is integral with By pushing the aforesaid thumbpiece back and forth on the tang, the stop 0 is thrown in and out of engagement with the trigger, so as to either prevent the action thereof on the sear,or liberate the trigger to allow it to throw the sear out of engagement with the cooked hammer when desired.

Inasmuch as the hammer is cooked automatically with the movement of the barrels from a closed to an open position, it becomes essential to also throw the safety-stop into engagement with the trigger automatically with the aforesaid movement of the barrels, and to effect this we employ the following instrumentalities, Viz:

Vertically in the breechblock A we pivot a post, Z, which projects through the top of the breech-block and has affixed to its outer end a rearwardly-extended lever, Z, by which to turn the said post.

The lower end of the post is provided with a stud-pin, t, which stands eccentric in relation to the axis of the post and has connected to it the locking-bolt m.

Thus by swinging the lever Z to one side the post Z is turned sufficiently to cause it to draw the bolt m out of the notch of the lug L of the barrels, and the latter are thereby liberated and allowed to be thrown into an open position for loading the same.

Underneath the tangD is an arm or bar, p,

one end of which is connected with the safetystop 0, and the opposite end is connected with the side of the post Z, so that in turning the latter the arm-p is pushed rearward and thereby caused to throw the safety-stop 0 into engagement With the trigger T. The connection of the forward end of the arm p with the post Z is made by a pin projecting from the post through aslot in the arm, which slot is of sufficient length to allow the arm to remain dormant while carrying the lever Z back to its normal position, and-thus maintain the safetystop in its engagement with the trigger. Said stop is thrown out of its engagement when i the under side of the barrels, and is fitted to desired by pushing the thumb-piece h forward. The forward end of the arm 12 is shown. in a separate view over Fig. 4 of the drawings. n represents a spring arranged to normally hold the post Z in position for retaining the locking-bolt interlocked with the lug of the barrels. C denotes the fore end, which is secured t o bear with its rear end against the forward end 7 of the breech-extension, the bearing being concentric with the axes on which the barrels swing, and that of the fore end being formed on the end of the metallic foreend strap M, which is countersunk in the inner face of the fore end, as shown in Figs. 5 and 6 of the drawings. The attachment of the fore end to the barrels is effected by means of 2. lug, N, projecting from the under side of the barrels and provided on its forward face with a notch, T, which lug enters a mortise in the fore-end strap and fore end.

In front of thelug N is a catch, 8, pivoted to the fore-end strap and adapted to engage the notch 1'. A spring, 15, attached to the strap M, is arranged to press the catch toward the lug N and yieldingly hold said catch in engagement with the aforesaid notch 7'.

The described connection of the fore end with the barrels leaves the exterior of the fore end intact, and facilitates the attachment and detachment of the same.

Having described our invention, what we claim as new, and desire to secure by Letters 5 Patent, is-

In combination with the breech-extension provided with a longitudinal mortise and a barrel hinged on said extension, a hook-shaped lug on the barrel entering the mortise, a ver- 10:) tically-elongated channel extended horizontally through the breech-extension, a pin extended through said channel and engaging the hooked log of the barrel, a lever pivoted on the lock-frame and having one arm con- I05 nected with the aforesaid pin, a tumbler pivoted between the hammer and lever and connected with the latter, the hammer provided with a cam over the adjacent end of the tumbler, and a spring arranged to press upon said I 10 cam, substantially as shown and described.

In testimony whereof we have hereunto signed ounnames and afiixed our seals, in the presence of two attesting witnesses, at Syracuse, in the county of Onondaga, in the State I r 5 of New York, this 30th day of July, 1884.
