PATENT OFFICE.

The purpose of the present invention is to produce an improved trigger mechanism for firearms with butt locks. This new trigger device should make it an absolute one Security against pulling the trigger if the lock is not yet fully locked become, while in connection with the actual trigger at the same time an ejector and a stop piece are arranged in such a way that the former when opening the closure in the cartridge path occurs and forms the lower material to the ejector of the cartridges, while the latter protrudes at the rear of the tail piece into the path of the sealing piston and in to descriptive way an unintentional, complete pulling out of the sealing piston from the housing prevented.

Such a device is shown in the accompanying drawing, which shows:

Fig. Ι a vertical longitudinal section through the head part of a piston lock rifle Partial view of the stopper in the open state.

Fig. Ι a is a cross section according to xy, Fig. 1, through the closure cylinder and through its guidance in the tail piece.

Fig. 2 is the same section as in Fig. 1, but with the shutter closed in the cocked one Conditions.

Fig. 5 shows the sear in the same five views.

Fig. 6 shows the ejector in side and rear views.

Fig. 7 shows a side and rear view of the trigger itself or the tongue with the Stop piece for the sealing piston.

In all the figures, the same letters denote the same parts.

In the accompanying drawing, for example, the trigger mechanism is in connection with shown a straight pull closure, but it remains the same as from the following description it can even be seen on which system of piston closure the trigger mechanism is attached.

It is A the locking housing, A ¹ its tail piece, B the locking piston and C the firing pin with the clamping nose or catch C ¹ .

The locking piston is provided below with the lateral guide ribs cc ¹ , which are guided in the grooves α α ¹ , as indicated in Fig. Ιa, while the clamping nose C ^{1 of} the firing pin runs in a groove a ² .

The trigger itself consists of three parts, the middle section d, the tunnel e and the tongue g. The center piece d can be rotated on a pin at d ^] below the lock and is provided with the arm d ² reaching backwards, on which the angled arm g ^{l of} the tongue g rests. The upper part of the tongue is only loosely in a corresponding recess in the lower part of the locking housing respectively. its tail piece is inserted and rests, as mentioned above, with

his arm g ^l on the arm d ' ^{2 of} the middle piece d , in such a way that it is impossible for the tongue to fall out. On the axis d ^{l of} the middle piece d sits, preferably with its lower part e ³ guided in an opening d ^h by d , the sear e, which has ^{its pivot point at e 2} on the above axis and is provided with the sear e ^l .

The middle piece d is provided at the bottom with a bore d ^s at an angle to the opening d ⁵ , in which a small spring h sits which, pressing against arm e ^{3 of} the sear e , keeps its nose e ¹ always upwards. At the front, the center piece d is provided with the projection d ⁱ , which serves to prevent the premature pressing. This is done in the following way: In the normal position, the upper surface of the projection d * is in the same plane with the lower surface of a projection b located on the closure piston B close to its rear end, so that this projection when moving towards ^; and moving the piston B slides over projection d ^l. If the trigger or tongue g is pulled backwards, its arm g ^l , supported at the rear against its bearing in the tail part A ¹ , swings with its front end downwards, and by acting on arm d ² of middle section d , it causes a movement of the the latter about its axis, which, since the fulcrum d ¹ lies in the middle between projection d * and lug e , has the consequence that nose e ¹ of lug e moves downwards and projection d ⁱ moves upwards.

For both parts d and e, since they do not change their position relative to one another during this movement, can be regarded as a whole body.

When the locking piston is moved forward, the trigger nose C ^{1 of} the firing pin C hits the sear nose e ¹ ; Between the beginning of the tensioning and the complete closing and locking, the locking piston still has to cover a certain distance, which depends on the arbitrary degree of tension which one wants to give the mainspring. The length of this path, for example, can be seen from the difference in the length of the firing pin visible in FIGS. 3 and 2. The same or approximately the same length of this path must now have shoulder b on the underside of the sealing piston, so that if the tongue is pulled in any position of the latter during this path, the above-described swinging of the center piece d about its pivot point becomes impossible because of this Projection af * rests tightly against the lower surface of shoulder b of piston B and therefore cannot move upwards. The natural consequence of this is that the sear e cannot move downwards either and therefore prevents the firing pin from loosening ( ^{triggering) in this position by holding the trigger nose C 1 open.} A suggestion of the firing pin in this position, in which the mainspring is already partly cocked, but the locking of the bolt has not yet taken place or at least not yet sufficiently taken place, could cause the cartridge to fire prematurely, which may be extremely dangerous for the shooter dangerous throwing back of the sealing piston would result. This is completely avoided by the device described. Only when the locking piston is fully inserted, i.e. securely locked, has approach b of the piston passed projection i *, and the free or recessed point b ² on piston B located behind approach b now allows entry of the piston B when the tongue is pulled Projection d *, so the swinging of the center piece d and thus lowering of the sear nose e ¹ , whereby the firing pin is freed and the Schufs is fired. The actual pulling off is preferably effected by the pressure of a nose g ' ^{3 of} the arm g ' of the tongue g against the rounded surface d ^{1 of} the piece d .

Trigger nose C ¹ has almost completely passed the trigger nose e ¹ after the trigger, and when the stopper piston is retracted (opened), nose C, the lower surface of which is bevelled backwards for this purpose, pushes the trigger shaft e, sliding ^{over its nose e 1} , down enough to be able to pass it. The cleat e swings around its axis common to d and is pushed back up into its original position after passing the attachment point of the spring h.

As can be seen from FIGS. 1, 2 and 3 of the drawing, the guide extension g ′ ^{1 of} the tongue g extends through the tail part A ^{ and protrudes above into the sealing piston path, where said extension g ^{2 is} cut out or forked, as shown in FIG. 7 can be seen to let approach b and nose C ^{1 of} the firing pin pass.

The two fork ends of approach g- are straight towards the front and are positioned so that when the locking piston is pulled out completely, its guide ribs cc ¹ , Fig. I and ia, meet the same, thereby preventing the piston from being inadvertently pulled out completely from the housing. At the back is approach g ' ² , as can be seen from the drawing,

bevelled downwards and forwards and leans against an equally bevelled surface in the tail part A ¹ , so that when the closure is withdrawn by striking its ribs cc ¹ against the attachment g-the latter cannot be pressed downwards. If the piston is to be pulled out (removed) completely, push the tongue g forward; as a result, approach g ² is pulled down by the trigger arm g ^{l is supported} with its front end against the upper inside of its storage in the tail piece A ¹ .

In connection with the trigger mechanism described above, an ejector device is used, which consists of one piece / which is movably attached to the front end of the trigger piece d. For this purpose, piece / is provided with the hole / ² , through which a pin or pin is inserted, which forms the pivot point of piece /. Piece / is provided at the front with the nose / ¹ reaching upwards into the lock housing, which is always pressed upwards by the action of a suitable spring. For this purpose, for the sake of simplicity, I prefer to use the spring h, already described above, located in the trigger part d , which therefore finds its support point with one end against the stud e and with its other end against the part / its support point. The ejector nose / 'stands in its natural position in the closure housing in the path of the closure piston, but is always depressed by the latter as long as it is completely or only partially closed. In the completely closed position, approach b of piston B comes to stand over nose f ^l and this approach must therefore be provided with a sufficiently deep incision b ¹ to enable passage over nose / '. Nose / is only used when the shutter is almost completely open and a cartridge or. Sleeve is to be ejected. To make this possible, the locking cylinder is BEZW. the closure head at the front below with an incision b ^s , which is deep enough to bezw the entrance. to allow the ejector nose / 'to rise into the piston or, what is the same, cartridge path. The position of the incision b ⁹ to the rear is dimensioned so that the nose / ^{1 can} rise shortly before the stopper piston has completed all its way backwards, so that the bottom of the returning cartridge or case only hits the ejector nose f ^{1 and} is then withdrawn a little further, which results in tilting them upwards, i.e. their ejection. The nose / 'thus replaces the well-known ejector pin that is otherwise permanently attached to the housing.
