PATENT OFFICE.

The present invention relates to the construction of hammer locks for the us under No. 49192 patented »straight pull rifles« and for Hammerschlofs rifles in general.

These innovations are shown in the accompanying drawing and it shows:

Fig. 4 also shows the castle with the cock pushed back, but with the spring relaxed,

Fig. 12 shows a modification of the same.

As stated in our patent no. 49192 known from the cylindrical closure head B and the closure piece B ¹ , here preferably carrying three closure warts, which is rotatable on the rear tapered end B ^{2 of} the cylinder B.

The rotation of the locking part B ¹ for locking and unlocking is effected by the handle lever C, which acts on the inclined surface d ^{on part J5 1} when turned forward and on the corresponding surface d ^{l when turned backward.} At the rear of the part B ² a cap D is attached, which forms the closure and serves to cover the flat handle lever part; At the bottom, the cap D is provided with a guide rib D ¹ which, when the shutter is moved to and fro, runs in a groove made in the bottom of the shutter housing. The locking cylinder part B is drilled through in the center and serves to receive the firing pin m on which the helical spring η is attached, the purpose of which is to push the firing pin back enough so that it can be hit by the hammer; at the front the cylinder B is closed by the screwed-in head B ^s .

The cartridge puller r in Fig. 11 is inserted transversely into a corresponding opening of the locking cylinder by means of the extension ^{r 2 and brought into its correct position by turning it around,}

in which it is held by the nose r ¹ that fits into a corresponding recess in the locking cylinder. The cartridge puller shown in FIG. 2 is completely supported in a longitudinal groove in the lock cylinder, so that no special groove is required in the lock housing. The cartridge puller is provided with a wart r ² , which has inclined surfaces and fits into a corresponding recess in the locking cylinder to the side of its longitudinal groove. The nature of this connection not only prevents any forward movement of the cartridge puller, but also, due to the inclined surfaces, causes the puller to pull itself further into its groove in the locking cylinder when the puller claw is tightened on the edge of the cartridge, making it impossible to jump out. The main advantage of this cartridge puller is that when the lock is closed there is no externally visible space between the cylinder and cartridge puller, so that no dirt can enter from the outside between the cartridge puller and the locking cylinder. Opposite the cartridge puller nut, a corresponding parallel nut can be attached in the lock cylinder, which runs over a pin in the lock housing and limits the backward movement of the lock cylinder.

Below the lock, the hammer h is mounted inside the lock on a pin h ^1. The back of the cock h is provided with a cutout h ² , in which the front end of the striker spring k is inserted, the rear end of which is fastened in the lock ^{by a screw / c 1 or in any other way.} Instead of the simple spring, a V-spring can also be used, the other arm of which is supported at any point on the lock. Under the spring k goes across the castle a respectively in the castle housing. in the lock plate L rotatably mounted pin Z through which can be obtained a partial (half) rotation by means of a ^{lever Z 1} on the outside, preferably on the right of the rifle. The part of the pin Z lying under the spring k is provided with a flattening, indentation or an incision Z ² , which allows the spring k to move downwards. So if lever Z ¹ respectively. Pin Z is rotated so that its recess Z ² faces the spring, the latter, which has a tendency to push downwards, will enter the recess Z ² and its front end here on the underside of the cutout h ² in the faucet h act, whereby the same is rotated backwards, as Fig. 2, 3 and 6 illustrates.

Instead of in the notch h ^{2 of} the faucet, the end of the spring k can also lie in a corresponding cutout in the nut of the faucet or instead of in an incision between two pins replacing this incision.

In the position indicated above (FIGS. 2, 3 and 6), the spring k is not only relaxed, but also holds the cock in a secured position from which it does not snap forward, even when released by pulling the trigger and can hit the firing pin. If the pin Z is now turned by means of the lever Z ¹ , its full or higher part comes to lie under the spring k and the same is thereby lifted or tensioned so that its front end now ^{acts against the upper side of the tap opening Zi 2} , as this can be seen from Fig. ι in the opened position, and in Fig. 4 in the cocked position. In the latter position, the spring k acts on the cock in the same way as the previously known springs. The trigger mechanism can be constructed as desired; For example, in connection with the trigger i, which is ^{rotatable on pin i 1} , we use a cleat i ² swinging on the same pin i ^l , which is pushed upwards by a coil spring i ³ housed in the lock housing, and which the trigger triggers by moving against it Neck i * pushes when withdrawn.

The interaction of the straight-pull lock with the hammer lock just described is as follows: In order to first allow the head of the cock to pass upwards and to strike the rear end of the striker m , the lock cylinder part B ¹ , as well as the part B ^{2 passing through the latter, are} below with a cutout s respectively. s ² provided (Fig. 7 to 10). In order to facilitate the attachment of these cutouts, instead of two locking warts, their three bbb are attached, as shown, and correspondingly the locking housing A is provided with three recesses, as well as with a slot s ³ for the passage of the tap. The slot s ^s in the closure housing, as well as the slot s ² in the non-rotatable part B ^{2 of} the closure cylinder, need not be wider than to allow the cock to pass upwards. The slot s in the rotatable part or locking ^{piece -B 1} must, however, be wider by the width of the warts bbb in order to permit the unlocking of this part when the tap is released. If, however, the slot 5 were to be allowed to extend to its full extent, it could happen that an accidental triggering of the cock with the shutter not yet locked would cause the shot to go off and thereby cause a misfortune. In order to avoid this, slot s has twice the width, not through its entire length, but is

shortened at the front by a sloping surface s ^1. So as long as the lock is not locked. is, the inclined surface s ^{1 of} the part B ¹ stands in the way of the tapping of the striker m , as illustrated in FIGS. 8 and 9. Only when, as can be seen from Fig. Ι ο, the shutter has been locked by turning the piece B ¹ to the right, the passage for the hammer to the firing pin is free. After the tap is struck and in the in Fig. 1 respectively. ι ο is the position shown, the same, if for the purpose of unlocking the handle C is withdrawn and thereby locking part B ^{1 is} rotated to the left, respectively displaced by the inclined surface s ^{l of the latter.} turned downwards and then completely put back or cocked by pulling out the locking cylinder. Due to the arrangement described above, the shot cannot go off before the bolt is completely locked, because even if the hammer were to strike before the bolt was locked, it would either be stopped by the inclined surface s ¹ or by its action on it by part B. ^{Turn 1} to the right, i.e. lock.

The type of locking and unlocking of Hammerschlofs rifles described herein by completely relaxing and re-tensioning the mainspring or springs is also for hunting rifles, especially for those with covered taps, the so-called tapless ones Rifles, of importance, on which this safety is easy to attach.

Claims (1)

Patent claim: Lock for hammer rifles, in which the mainspring k is under the influence of an eccentric / ² , so that in one position the spring k pulls the hammer back into the tensioning detent, while in the other position of Z ² the spring k tries to hurl the hammer forward is.
