IMPERIAL

PATENT OFFICE

The present invention aims that To simplify the firing device in rapid-fire guns and at the same time the To increase security against premature firing.

The present invention is intended in its application to the German Reich patent No. 45580 of the inventor protected screw locking device described if it is also applicable to other locking constructions. The locking device is only described as far as necessary to understand the tensioning device is.

The present innovations relate to that class of rapid-fire guns which the breech cylinder in the rear end of the gun through interlocking interrupted thread is locked.

Such guns were usually given an extractor to empty them Retracts cartridge cases when the locking cylinder is withdrawn, so that the The cartridge case is still partly in the barrel when the locking cylinder is turned to the side has been.

. According to the present invention, not only an extractor is attached to such guns which pulls out the cartridge case when the locking cylinder is retracted is, but also an ejector, which snaps the cartridge case out of the tube after the locking cylinder to Is turned \ forward.

Fig. Ι is a view of the rear end of the gun barrel with the breech established.

Fig. 2 is a section along the line ed, Fig. 3 is a section along the line ef, Fig. 4 is a cross section of the locking cylinder.

A is the rear end of the gun barrel, B the locking cylinder, C the ring, D the axis around which it can rotate. The extractor is indicated at E. F is a roller carried by ring C which engages a groove on the side of the lock cylinder.

The construction of the lock, as far as it has been described so far, is from that of the Patent seeker belonging to German Reich Patent No. 45580 known.

H is the ejector lever rotatable about a ball joint H ¹ , H ² is a projection at its rear end, which enters a groove C ¹ in the front surface of the ring C. C ² is an arm protruding from one side of the ring C. C ³ is a shoulder on the front surface of this arm, which ^{abuts against a stop ^ 1} at the end of the gun barrel when the breech is open.

/ is the firing pin, which lies in a central cavity in the locking cylinder. It has a hollow cylindrical shaft I *, the rear end of which enters a corresponding cavity in a block B ^J which closes the rear end of the cavity in the closure cylinder. The shaft I ¹ has two approaches P which, protruding from the same, enter corresponding grooves in the sides of the cavity in the block B ¹ and the impact

Prevent bolts from rotating. The block B ^ϊ is designed to be square on the outside and fits into the rear end of the cavity in the locking cylinder, which is of a corresponding shape. It is held in its place by a pin / which also forms the pin for the handle K , by means of which the locking cylinder is given a rotary movement when the lock is to be opened or closed. L is a coil spring in the hollow shaft of the firing pin, through which the firing pin is shot forward.

M is the trigger by means of which the firing pin is kept cocked after it has been withdrawn. JV "is a pin located in a radial hole in the lock cylinder that rests on the tail of the trigger.

O is a pin in a radial hole in the gun barrel, which is in a straight line with pin N when the breech is closed. P is a coil spring that pushes this pin outwards. Q is a bell crank; one arm of the same rests on the outer end of the pin O, and a cord is attached to the other arm; If you pull this cord, the trigger bar can be released when the locking cylinder is properly locked.

The handle K has eccentric hooks K ¹ which engage in cavities on two opposite sides of the block B ¹ and which, when the handle is turned so that it protrudes outwards, engage under pins J ² which are located on two opposite sides of the The shaft / 'of the firing pin / protrude and cock the firing pin by pulling it back.

As long as the handle remains turned outwards, the hooks K ¹ stand in front of the pins / ² and the firing pin cannot be snapped forward so far that its front end hits the cartridge; therefore, the gun cannot be fired until the handle is flat against the breech cylinder. One arm of the handle carries a shoulder K ² , which prevents the handle from rotating in this position, except when the locking cylinder is properly locked. The approach on the handle can then enter a recess in ring C. In this way it is impossible to fire the gun before the lock cylinder is properly locked.

Figures 5 through 12 show some of the details in separate views, namely:

Fig. 5 is a top view of the handle and hooks and

Fig. 6 is a section through the same.

Claims (1)

Patent claim: An ignition lock for gun screw locks, in which the firing pin is tensioned / caused by the fact that the handle K , which is to be folded up for the purpose of opening the lock, grips under the projections I ^{2 of} the firing pin by means of eccentric sliding surfaces K ¹ and in which the gun is only fired after complete locking of the locking cylinder after entry of the handle attachment K ² in a recess of the ring C can be made. For this purpose 2 sheets of drawings.
