PATENT LETTERING

CLASS 72: Firearms and projectiles.

Patented in the German Empire on October 11, 1887.

From the drawing, the rifle in Fig. 1 is in a vertical longitudinal section in unloaded, when closed.

Fig. 2 is a same section of the rifle in the loading state with its latch ν cocked Stop cock P.

Fig. 3 is a similar section, the rifle in the loaded state, with the trigger rod R resting in the detent ν, ready for firing.

In order to keep the rear material off the shoulders of the shooter when the rifle is fired and to be able to use it for opening the lock and ejecting the empty cartridge case, I have divided the rifle stock into two telescoping stocks A and B.

The rifle stock thus consists of a fore-end .4 with a lock case G and a rear-end B ending in the butt.

The shaft ends C and D, which correspond to one another, are provided with double-cylindrical guides E and F fitted into one another so that the fore-end A can be pushed into the butt-end B from α to b .

In order to maintain the stocks A and B in the position shown in FIG. 1 until the return material enters when the rifle is fired, the rear stock B is correspondingly drilled to accommodate a helical spring H acting there.

From here, the entire shaft B and the guide piece C are also drilled through for the implementation of the steel rod J according to its thickness.

The steel rod J is screwed into the cylindrical part F of the fore-end A; the same is provided with a screwed-on buffer washer K and sits on the helical spring H which is supported against the piston cap L.

By pressing on the buffer K of the steel rod J helical spring H , the cylindrical guide sleeves E and .Fbezw. the fore-end A held by the butt-end B at a corresponding distance (a to b) from one another.

The guide cable C of the buttstock B is attached at the bottom in its extension to the rear of the stock B by screws, as is the upper piece of flap N, which is let into part C.

The guide rope D of the fore-end A is made from one piece with the lock case G.

In the lock case G is the block O, mounted with its lateral pins c and c ¹ in the walls of the lock case G and protected from jumping out upwards and as a guide by the pin bearing cover M.

The block O is drilled out to receive the firing pin X and at its rear end to receive the nose 0 of the firing pin X

provided with a slot d . The block O is also provided on its lower head part with the recess f , into which the eccentric nose h of the cock P for opening and closing resp. Lifting and lowering of block 0 engages.

The hammer P is also located in the lock case G on a transverse screw i that goes through the same and simultaneously fixes the journal bearing cover M , and ends in the lever P ^{1 extending outside the lock case G.}

A recess m is made on the hammer P, into which the hammer spring S engages and keeps the hammer P cocked.

R is the trigger bar, which is pressed into the detent ν by the spring y.

T is the cartridge ejector, which sits on the screw k going through the lock case G and is inserted in a vertical position in the part U of the lock case G which forms the barrel.

The piece Z is fastened at the bottom to the cylindrical part C of the buttstock B with screws and ends in a fork-shaped manner, in order to allow free movement in the fork of the trigger bar at the rear of the rifle.

So that the piece Z can slide into the cylindrical part D of the lock case G when the back material has taken place, it is worked out in a corresponding manner.

The lid V , which closes the lock case G downwards, is provided on its outside with a shoulder through which a screw / passes, by means of which the mainspring S can be pushed up and the rifle can be secured against involuntary triggering.

In order to prevent the fore-end A from playing on the helical spring H located in the rear stock B during official use, I have an open spring sleeve r to insert between α and b respectively. arranged between the fore-end A and the butt-end B , whereby the rifle is secured against any movement.

The bracket W of the rifle is connected and fastened to the butt stock B and to the piece Z by screws.

If the lock G is to be brought from the state shown in FIG. 1 into the loading position, FIG. 2, the lever P ^{1 of} the cock P is pushed forward in the direction of the arrow; As a result of this pushing forward, the cock P stretches beyond its detent ν , as can be seen from FIG. 2, and the block O lowers, hitting the leg t of the ejector T and moving it from the position of FIG. 1 to that of FIG. 2 bringing.

The knocked back ejector T engages with its lugs η in the attachment ρ located on the block O and the block O is thereby held in the position shown in FIG.

If the cartridge is now to be pushed into the barrel opening U , the block O is pressed down a little with the thumb, thereby the ejector T releases the block O at approach ρ and the ejector is gripped by the edge of the cartridge on its lobe g and taken away. As a result of the pressure of the spring S on the cock P , the block O is guided by the nose h engaging in its recess f , closing the lock upward, and at the same time the cock P goes back into the detent v, FIG. 3, and becomes held there by the trigger bar R until firing.

When the rifle is fired, the rear stock of the fore-end A thrusts into the butt-end B from α to b, shifting in the cylindrical guide parts E and F.

This rear material is, however, caught by the steel rod J screwed into the cylindrical part F of the fore-end A , provided with the buffer washer K and seated on the helical spring, and the tension of the helical spring H causes the fore-end A to return to its previous position after the rear end .

During the return movement, the lever P ^{1 of} the hammer P is pushed forward by the bracket W in the direction of the arrow, this opens the lock G, the block O falls on the leg of the ejector T and the cartridge is pushed by the block O on the Leg t of the ejector T is ejected from the rifle barrel U by its rag g located behind the edge of the cartridge, and the ejector T holds the block O through its nose η at its base ρ and the lock is again in the loading state, Fig. 2.

Claims (2)

Patent Claims: ι. In the case of rifles with block breeches, the arrangement that the bolt housing (G), which is firmly connected to the barrel and fore-end, can move back against the buttstock (B) in order to utilize the rear material of the rifle to open the block breech and to tension the lock. 2. The execution of the arrangement marked under 1. as follows: a) that the tensioning lever (P ¹ ) connected to the hammer (P ) when the lock housing retreats from the rear the shaft is pre-pressed under tension of the mainspring (S) and thereby the block (O) is lowered by a nose (h) of the hammer and caught by a nose (g) of the extraction lever (T);
b) that the lock housing and the piston neck are elastically connected by two interlocking hollow cylinders D and E, the bolt J arranged on the lock housing and the helical spring H arranged in the buttstock B in order to reduce the residue. For this purpose one sheet of drawings.
