vpeating ire arm, in so far as the arrangement of a releasable breech bolt arresting device also permits non-automatic single shots to be fired in a suitable order of succession both when using the magazine and during single loading by hand.
This invention also relates to a new device by which the receded barrel, after firing, is secured in the rear position until the locking z'. e. the coupling of the breech bolt with the barrel commences. The locking mechanism arranged in connection with the trigger mechanism forms another feature of the invention and when adjusted in the lockingy position, it prevents the striking of the hammer upon the ring pin, or only permits a partial forward striking movement of the former, so that the hammer is secured in an intermediate position or is put at rest, from which position it can be returned te the cocked position by pulling the trigger tongue.
The. improved fire-arm is shown in the accompanying drawings and Figure l shows the gun in longitudinal section with removed lock-plate, the lock being unlocked t'. e, the hammer having struck forward and the breech being in the locking position and the barrel in the forward position. Fig. 2 shows the arresting device for the breech bolt in the position for automatically operating the fire-arm, thus for automatically loading, opening and closing the breech. Fig. 3 shows the gun with cocked hammer and locked trigger, the breech bolt receded and the barrel secured in the rear position. Fig. 3EL shows the locked trigger mechanism with the hammer in the intermediate position or at rest,` in which position the hammer is prevented from making a further forwardfstriking movement. Fig. 3" shows the unlocked trigger mechanism with the hammer in the act of striking forward unimpeded by the part, which otherwise secures it when the trigger mechanism is locked. Fig. 4 'shows the arresting device for the breech bolt inthe position for the nonautomatic operation of the fire-arm, in which position the arresting device secures the outer sleeve of the brocoli bolt in the rearward position after each shot. Figs. 5-10 show in different views the means whereby the outer sleeve of the breech bolt is opened by hand and also the parts which effect the release of the locking device of the barre-l.
The automatic operation of the rearm and especially the automatic opening and closing of the breech take place in the known manner. The barrel l, which is subjected to the action of a spring, is moved back into its guide after the firing of the recoil until the rearward face of its rear part, the so-callcd barrel sleeve, wholly or partly bears against the end of the barrel guide. The separation of the breech bolt lc from the barrel Z now takes place in such a manner that the breech bolt is turned, whereby the unlocking takers place i. e. the coupling between breech bolt and barrel is released, as by this turning movement of the breech bolt, the locking nibs of the same are so disposed independently of the corresponding projections of the barrel sleeve that on the further movement of the breech bolt, they can pass through the spaces between the projections of the barrel sleeve. After this turning movement, the breech bolt will slide back in a straight line until it reaches the rearward end of the receiver, whereupon it performs another turning movement, by which the locking is insured. This general operation of the lire-arm is known and has only been repeated here for the sake `of clearness. The general arrangement of the parts effecting the locking & unlocking of the breech bolt with the barrel is also known. In the present case, the turning movement of the breech bolt is effected by the cooperation of a guide pin k3 in the barrel sleeve with a helical shaped groove k2 of the breech bolt, while therectilinear guiding of the breech bolt is effected after the unlocking or before the locking by the engagement of the lug t' in the rectilinear groove la of the breech bolt. According to the inventiony there is provided laterally of the barrel sleeve, a releasable breech bolt arresting device r r, which has for its object, provided that the magazine is charged, or the fire-arm is to be used for non-automatic firing, to secure the breech bolt, which flies back after the shot, in its rearward position until the loading takes place by hand, whereupon by releasing the arresting device, the breech bolt will be released and permitted to move forward. This arresting device consists of a double armed lever r adapted to oscillate on the barrel sleeve and having its rear arm projecting with a suitably formed shoulder r in a recess t of the barrel sleeve. The lever r is under the action of a spring r3, which operates on its other arm and tends to cause the shoulder r to project into the barrel sleeve (Fig. 4) in such a manner that the receding breech bolt, which flies back after the shot, can slide over the shoulder but not move forward, as the breech bolt is secured by the shoulder r in front of one of its locking nibs.
. A slight pressure on the front end of the lever is sufcient for permitting the breech bolt to move forward again and for releasing the arresting device, whereby the shoulder r is moved outwards from the front of the breech bolt, so that the latter can advance forward under the action of its forwardly propelling spring into the locking position.
roo
Now in order to render the arresting device permanently inoperative for the automatic use of the firearm, the lever r has an adjustable projection r2 which is provided with an outwardly extending handle. The projection is so formed that when it is turned down withits handle directed forwards (Fig. 2) it secures the lever r in such a position that its shoulder r is kept in the recess 1) out oi the'path oi the breech bolt. I, however, the adjustable projection T2 is turned down with its handle directed rearwardly (Fig. 4) the lever 1' can be so freely adjusted under the action oi its spring r3 that its shoulder r is adapted to arrest the breech bolt in the manner hereinbeore described.
As already mentioned, the fire-arm, according to Y the present invention, has a further improvement,
which relates to means, the object of which is to secure the barrel in its rearward position until the locking commences t. e. until the locking nibs oi the breech bolt have passed through the already mentioned recesses of the barrel sleeve into the barrel sleeve itself.
Now according to the invention, a very simple device has been provided for this purpose, which comprises a lever m oscillating at the front of the magazine box'and having its lower part m3 so formed that it can receive the spring, which actuates the lever. At the iront end oi the lever m is a hook-shaped projection m2, which is adapted to engage with a corresponding shoulder l2 o a projection l of the barrel sleeve. I the barrel has moved toits rearmost position, the lever m with its projection m2 moves automatically under j sleeve o and engages by means of a projection n2 the action of its spring in iront of the shoulder Z2 and secures the barrel (Fig. 3). The lever m is provided laterally with an upwardly 4bent lug m', which has for its object to effect the' release of the lever when the breech bolt advances. For this purpose, the bolt n (Fig. 8), which carries the breech bolt forwardly propelling spring d and is located in a lateral longitudinal in a correspoiding recess 7a4 (Fig. 6) oi they breech bolt, has at, its iront end an abutting arm n which, when the breech bolt advances or the spring bolt 'n moves orward (after the locking nibs have passed through the recesses of the barrel sleeve), bears upon the lug m and thereby annuls the engagement oi the lever m with the projection l o the barrel sleeve, or interrupts the engagement of Z2 and m2, so that the barrel can advance again under the action o i its forwardly propelling spring. On the side of the sleeve o, which has a slot 02 so as to form a guideor the projection r1.2 engaging in the breech bolt, is provided a slide p with handle p for opening the breech bolt by hand (before the rst shot). For this purpose, the slide has at its front end a projection q, which engages in a slot 'n3 o the head of the spring bolt n and whose path is in a longi! tudinal groove o in the outer wall of the sleeve o. When opening the'breech bolt by hand, the spring bolt n and the breech bolt k can be withdrawn by means of the slide p in consequence o the engagement of q in n3; during automatic, ring, the slide p however remains stationary, as the spring-bolt n can freely slide backwardsA on the projection q without taking the latter with it. Y j In the fire-arm as shown, the trigger lever 2 subjected to the action of a spring-bolt c is adapted to os`cillate within the box, which contains the striking parts and the trigger mechanism.I The arm of the said trigger lever projects into the trigger guard and orms the trigger tongue. A longitudinal push-bar g is pivoted to the other arm o this trigger lever and carries an upper push-bar g acting on the sear e. This upper push-bar g is subjected to spring pressure 'andgenerally bears (Fig. 1) against the lower shoulder oi the sear e, which is under the action oi a spring f. The sear has a lug e i with which it can engage over the hammer h oscillating in the box. .This hammer h is moved by the receding breech bolt into the cocked position and is secured in this position by engagement with the sear nib e (Fig. 2)
the engagement of h & e being maintained by the action oi the said spring f. For this purpose, the hammer is provided at its upper edge with a lug h, which correspends with the lug e and the sear e in such a manner that in the cocked position of the hammer, both lugs are adapted tol engage with one another. The lower push-bar g, which, as already'stated, is linked to the inner arm oi the trigger lever z and carries near to vits joint the upper push-bar g 'extends nearly to the lower part oi the hammer and is generally, as shown in Figs. 1 & 3, freely. advanced beneath the hammer when pulling the trigger tongue. There is provided beneath the upper push-bar g in the trigger guard plate, which closes thc box below, a longitudinally movable locking member s, which has a shoulder s within the box. This locking member s, when unlocked and projecting rearwards into the trigger guard t (Fig. l) is so adjusted that the shoulder s is out of reach oi the iront end q2 of the lower push-bar g so that, as already' stated, the latter can pass into the recess t2 of the trigger guard plate t. Thus when the locking member s is in the unlocked position, the hammer h can freely advance (Fig. 3b) and when coming vin Contact with the firing pin, the cartridge explodes. Ii, however, the locking member s is out of the trigger guard and adjusted in its foremost position (Fig. 3) the shoulder s` is located beneath the iront end gz o the lower push-bar g. This end of the push-bar g is kept in the elevated position in'such a manner that when the trigger is actuated, the forward end oi the lower push-'bar is within reach o a shoulder h2 of the lower part oi thejhammer h. The hammer can thus only strike a certain distance forward, the shoulder h2 then bears against the outer end oi g2 and the hammer is secured in this intermediate position or is put at rest (Fig. 3). li the trigger tongue is drawn back iurther; the movement of the hammer will be reversed i. e. the hammer will-'be returned to its original arresting position, wherein the previously released sear engages with the head of the hammer (Fig. 3)). On drawing back the trigger tongue, the hammer can still only advance a certain distance, it is then secured and on pulling the trigger tongue, .the hammer returns to its original arresting position; thus a discharge oi the gun after firing, said locking device comprising a hook pivoted to the frame, a spring for moving said hook into operative position, a lug upon the barrel sleeve having a shoulder adapted to engage the hook, means yfor disengaging said hook from said lug, said means adapted to be operated as the breech bolt advances, and consisting of an arm carried by the bolt n which carries the breech bolt spring.
2. In an automatic fire arm with slidable barrel, the combination of the trigger mechanism comprising a trigger lever, an upper push bar, and a sear'arrestng the hammer, with a locking device for preventing the forward striking of the hammerA and having a lower push-bar connected to the upper push-bar and a lockin'g member moving along the trigger guard plate, said lower push-bar being adapted to prevent the hammer from striking'forward when the lock ing member is moved forward and also to return the hammer from its intermediate position, to the cocked position, substantially as described and shown in the drawings.
3. In a firearm, a trigger, means adapted to cause said trigger to release the hammer, and means adapted to return it to its cocked position before it reaches the tiring position.
