PATENT OFFICE.

The invention described below relates to a straight pull rifle, in which the opening and closing simply mediate a straight back and forth movement of the locking cylinder is executed, the latter at the beginning of the backward displacement respectively receives a rotating movement at the end of the shutter. This type of rifle is now a device is attached, which makes it possible to tilt with the weapon without touching the trigger. This is attached, for example, to the trigger spring Projection achieved that the nose of the firing pin when advancing the locking cylinder stops, thus cocking the striker, while in the last part of the advance occurring rotation of the locking cylinder. the nose slides off the projection and with it firing occurs. According to the present innovation, therefore, it becomes an automatic one Firing of the rifle obtained when the breechblock is closed. If desired, can but - the rifle can also be fired in the previous "way, i.e. by the trigger, and the latter can also be adjusted in such a way that the rifle is secured against any firing.

In order to understand the invention, let us first consider the device of the straight-pull locking rifle discussed.

The locking cylinder b of the rifle has, as can be seen from FIGS. ^1, 2 and 6, two rows b l and b ^{2 of} protruding grooves, so-called blocking wings, and two corresponding rows of blocking wings a ^l and a ' ² are mounted inside the breech housing α (Fig. 5). The two rows of locking vanes of the locking cylinder and locking housing are offset to one another, in such a way that when the locking cylinder b is pushed into the locking housing α, the cylinder must be given a certain rotation when its locking vanes b ¹ and b ^{2 are} in the straight grooves between the

Blocking wings a ^l and the blocking wings a ¹ should enter.

On the side of the closure housing α there is a ruler c, FIGS. Ι and 3, on which the bolt d ^{provided with button rf 1 can be} displaced. This bolt d has a protruding pin d °, Figs. 1 and 6, which enters a helically wound groove £ °, Figs. 1, 1 a, 2, 3 and 6, of the locking cylinder b . When the bolt is pulled forwards or backwards on the ruler c , the lock cylinder b is therefore shifted in a straight line in the lock sleeve, but in such a way that at the start of the movement backwards or respectively. at the end of the forward movement due to the influence of the groove b ° a rotating movement occurs at one and the same point. The purpose of this rotating movement is, on the one hand, to achieve a tight closure of the locking cylinder (in that the locking wings b ¹ and b ' ² on the one hand and α ¹ and α ² on the other hand, as can be seen from the drawing, are beveled and, by their coincidence, the locking cylinder b is bevelled forcing at the front) and on the other hand, loosening the fired cartridge by turning it in its bearing.

When the bolt is moved back, the locking of the cylinder b is released immediately and at the same time the cartridge (which is held by the locking cylinder in a known manner by means of springs) is rotated and loosened in its chamber. So that the rotating movement of the locking cylinder stops at the right time or. starts at feed, a coupling device is provided, consisting of the trap e, Fig. 2 and 3, which is with a pin in a hole in the bolt knob d ¹ and is pressed by a spiral spring e ° inward, with a pin e ¹ of Trap can enter a hole b ³ drilled in the locking cylinder. This pin e ¹ can only enter the hole b ^B if the bolt with its pin d ° has covered the way in the groove b ° , ie has rotated the locking cylinder, and if also the trap e in front of the curve of the Closure housing a attached bar f has arrived, so it can be pushed forward by the spring e °. Conversely, when the locking cylinder moves forward, a rotation for the purpose of closing can only take place again when the latch e has moved outward through the curve of the bar / and has thereby brought the pin e ¹ out of the hole b ^{3 of} the locking cylinder (Fig. 2).

Due to the double row of beveled blocking wings a \ a ' ² respectively. b \ b ² , a double, secure locking is achieved, and since these blocking wings are offset from one another, the rear blocking wings a ² serve as a stop for blocking wings b ^{1 and} b. for the closure cylinder b when the latter moves back.

Α to the Verschlufsgehäuse the apparatus is further mounted, which makes it possible to schiefsen with the rifle, without the trigger or pusher g usable. The trigger spring i of the shutter housing, Fig. 7, is slotted lengthways for this purpose, so that it consists of two resilient parts, of which one part i ¹ is moved downwards by the trigger arm g ^{1 of} the trigger g, which is held on one side can, while the other part i ² . (which can also be firmly attached to the rifle) stops (Fig. 5). Since now, as described, the locking cylinder executes a rotating movement in addition to the rectilinear movement when it is pushed forward for the purpose of slipping, the striker, which moves with its nose h in a longitudinal slot Z> ^{4 of} the cylinder, Fig. 1 and 4, must also do this join in the rotating movement. It is, therefore, if the trigger is in the position of Fig. 4. and 5 is brought, the projecting striker pin nose η to the stand permanent part i first 'Append ² of the trigger spring and then slide laterally in the further course of the rotation from P, whereupon the firing pin with its nose over the pressed downwardly part · i ¹ of the trigger spring can forward fast (Fig. 4).

The trigger is held in the position Fig. 5 by a spur k ^{l of} the axis k , which can be rotated by means of a small spring lever m attached to the rifle until the lever snaps into a suitable recess in the shield I (see Fig. -Fig. 5). In order to secure the loaded weapon, the axis k is rotated by means of the lever in until the hook k ' ² grips the trigger via the protruding extension K ² , FIG. 1, so that the latter cannot be moved. The lever m also secures this position by falling into a suitable recess on the other side of the shield Z. If, on the other hand, the lever m is brought into the intermediate position and also appropriately fixed here, the trigger can play freely and the rifle can be used in the usual way .

Claims (2)

Patent Claims: i. Device for the automatic firing of straight pull rifles when the breech is closed, consisting of a projection ^{(Ϊ 2} ), which stops the nose (h) of the firing pin when the breech cylinder is advanced , so that, if the trigger is switched off, when the To slide the locking cylinder, the projection (Ϊ ² ) on a special leg of the trigger spring (i), the other leg (P) of which is actuated by the trigger, can be arranged. 2. An embodiment of the under i. characterized device, in which one arm (k ¹ ) of an adjusting lever (kk ¹ ) that can be rotated on the rifle switches off the trigger (g) with the leg (P) of the trigger spring in such a way that the rifle can fire automatically when the slide is closed, while by putting the other arm (k " ¹ ) forward, the trigger and also the rifle are secured against any firing, but in the middle position of the lever the trigger can be moved in the usual way for the purpose of firing the rifle.
