EMIL FINKE in BREMEN. Throwing rifle.

The present invention relates to a device in throwing rifles, such as those used for Launching signal or oil rockets, throwing tow lines and the like for night signaling and are used for rescue services at sea to mitigate the massive return of such large-caliber rifles. this will achieved by the fact that the barrel is movably mounted on the rifle stock and on the Schufs slides backwards and caught by a pneumatic buffer and through the compressed air is returned to the firing position. For support this forward movement is served by a spiral spring, as is the case with the Rückstofs in a small one Cylinder, the pre-filled air is collected, which is fed into the large pre-cylinder as required after the return has ended can be let in and thereby propel the barrel forward again. The barrel can be pulled out by means of a bayonet catch Rifle lock and is pulled out each time to load a cartridge to be able to use.

The new throwing rifle is shown in the drawing in Fig. Ι in a longitudinal section. 2 and 3 show a longitudinal section through the castle on an enlarged scale; 4 and 5 show sections along the lines BB, AA of FIG. FIG. 6 illustrates a side view of the releasable connection of the rear end of the rifle with the rifle lock.

The rifle barrel 1 is slidably mounted in the rifle frame 3 with the rifle butt 40 is firmly connected. The guidance of barrel 1 takes place on the front part a sleeve 2 attached to the frame 3, which carries the front sight and means on the rear part of the rifle lock 5 instead, .which by means of two laterally attached, parallel with the Rifle core running guide rails 34 in corresponding Grooves 6 of the frame 3 runs.

To releasably hold the rear end of the barrel, the barrel 1 has three radially protruding Noses 9 and the rifle lock 5 are provided with corresponding grooves and noses 1 o located between these, in such a way that after Inserting the gun barrel with its lugs 9 through these grooves and turning the barrel around 60 ° the noses of the barrel lie behind those of the lock, that is, both parts are against each other are held. A rotatable on the barrel 1 in the bearing 12 is used to secure the hold held handle 11, which after its insertion between the webs 13 a rotation of both parts against each other and thereby also the loosening of the barrel prevents (Figures 4, 5 and 6).

The cartridge chamber of the barrel lies tightly against the fabric plate 51 of the lock housing 5, in which a central opening for the firing pin 18 is present. The latter itself is in a sleeve 15, as well as in the rear wall 8 of the lock 5 is stored. The sleeve 15 is by means of a side arm and a through A screw 35 fixed in the arm passing through a slot in the lock wall and is tensioned by a spring 50 placed around the firing pin, the nose 52 the firing pin sleeve is held in place by the cleat 36 of the trigger 16. Of the The trigger lever is loaded by a spring 46

and is by a lever 45, on which one is mounted in a groove of the frame 3, with the trigger 43 coupled trigger rod 17 acts, moved from its rest position. These Rod 17 is loaded by spring 44 and rotates when pulled by means of the nose 42 the Lever 45 and thereby also firing pin lever 16, so that the cocked firing pin 18 is triggered.

On the rear wall 8 of the lock housing 5 is the hollow piston rod 20, the hollow piston for the pneumatic return inhibitor, which is tightly sealed in the rifle frame 3 attached cylinder 7 is mounted. A second cylinder 19 is centrically located in the cylinder 7 arranged, which fits with its head in front of the hollow piston 20 and a stop for forms the piston 20 when returning the barrel after the creation. On the cylinder 19 a shorter cylinder 41 is connected, connected to the former by a flap 25 closed with a spring stands. Through a further flap 27 which can be operated from the outside by means of a handle 30 the cylinder 41 can also be connected to the cylinder 7.

In the cylinder 19 runs a piston 49, the Rod 21 also on the gun lock 5 respectively. whose rear wall 8 is attached. The piston 49 is provided with a bore, which with a through bore 53 in the front wall of the cylinder 19 is in communication. The channel 53 is closed on the inside by a flap 23. The hollow piston rod 20 and the cylinder 19 have flaps 22 respectively. 24. At the end of the cylinder 7, a flap 26 is also arranged, which from the outside can be opened.

Within the cylinder 7, a spiral spring 29 is arranged lying in the cylinder 19, which serves as a return spring and supports the action of the pneumatic brake.

The pneumatic return inhibition works in the following way: When Schufs is the Run ι thrown back through the Rückstofs and also the two pistons attached to it 20 and 49; the air in the cavities 28, 31, 32 and 33 of the cylinders 7, 41, 19 and of the hollow piston 20 is hereby compressed and the spring 29 is tensioned, and the rifle rear material is therefore elastically absorbed. As soon as the projectile has left the barrel, the compressed air in the cylinders, as well as the barrel back into the firing position due to the tensioned spring 29 returned, whereby a strong stop of the barrel at the end of the return movement as a result it is avoided that between the hollow piston 20 and the extension of the cylinder 19 and also between the piston 49 in the cylinder 19 and its inwardly jumping to the Piston rod adjoining approach when returning is each a layer of air, which is when returning is compressed again, whereby the return is slowed down, all the more than also in the case of the reverse, the air compressed in the hollow piston 20 through channel 53 into the cylinder 19 is pressed. The heavily compressed in cylinder 19 when the barrel was returned Air enters the cylinder 41 through flap 25, is collected there and can be used to return the barrel by exiting the cylinder 7 by means of a flap 27 or, when the return has ended, by transferring into the cylinder 7 increase the pressure in it, whereby the back of the barrel in the Schufs a more powerful, but always elastic resistance is opposed.

The hollow piston 20 is against so that the resistance during the return does not become too great the inner cylinder 19 is not completely sealed.

Through the flaps 22, 24 and 26 can BEZW in the hollow piston. in the cylinders 19 and 7 to allow air to enter again after the return flow.

For firing signal rockets, throwing lines, oil rockets and so on, a smooth one is used Used gun barrel. For example, it is assumed in the drawing that a line should be thrown. For this purpose a corresponding rocket is provided with a linen rocket Cartridge loaded, the conical rocket head 14 of which is loose on the gun barrel after being launched set towing sleeve 37 provided with control arms 39 to which the line 38 is attached, seized and carries the leash. The missile attachment located in the missile propels the missile even after leaving the barrel of the rifle, you can still move forward and get on with the burning Tail of rocket flight to be tracked.

With signal missiles and so on, a drag sleeve or the like is of course not required, but these are fired in the usual way.

If you want to use the same rifle for other crooked purposes, e.g. sniping, you can the smooth running event, to be replaced by a rifled one.
