Patentiert im Deutschen Reiche vom 13. Juli 1909 ab.Patented in the German Empire on July 13, 1909.

Den Gegenstand der Erfindung bildet ein Geschütz mit Schulterstück, bei welchem die Höhenrichtung während des Rück- und Vorlaufes des Geschützrohres mittels eines zwisehen Lafette und Wiege eingeschalteten Klemmgesperres festgelegt wird (vgl. z. B. die Patentschrift 102520). Das in dieser Druckschrift beschriebene Klemmgesperre ist so eingerichtet, daß es durch Kräfte, welche das Geschützrohr mit dem Bodenstück aufwärts zu drehen bestrebt sind, ausgelöst werden kann. Da nun erfahrungsgemäß derartige Kräfte (z. B. Reaktionskräfte des Rückstoßes) unter Umständen auftreten, will die Erfindung Geschütze der erwähnten Art dahin vervollkommnen, daß das Geschützrohr beim Rück- und Vorlaufe gegen jede Drehung um die Achse der wagerechten Schildzapfen gesichert ist.The subject of the invention forms a gun with shoulder piece, in which the Elevation direction during the return and forward movement of the gun barrel by means of a zwisehen The carriage and cradle are set when the locking mechanism is switched on (see, for example, the Patent specification 102520). The locking mechanism described in this publication is set up in such a way that that it is by forces which the gun barrel with the bottom piece upwards strive to rotate, can be triggered. Since experience has shown that such Forces (z. B. reaction forces of the recoil) may occur, the invention wants Perfect guns of the type mentioned in such a way that the gun barrel and leads secured against any rotation about the axis of the horizontal trunnions is.

Auf der Zeichnung ist eine Ausführungsform der Erfindung dargestellt, und zwar zeigt Fig. ι eine Seitenansicht des Schulterstückgeschützes; das Rohr befindet sich in Feuerstellung, das Klemmgesperre ist ausgerückt, Fig. 2 einen Schnitt nach 2-2 der Fig. 1, von oben gesehen, Fig. 3 einen der Fig. 2 entsprechenden Schnitt bei eingerücktem Gesperre. Fig. 4 und 5 zeigen in größerem Maßstabe eine Einzelheit des Klemmgesperres in zwei verschiedenen Stellungen.In the drawing, an embodiment of the invention is shown, namely shows Fig. Ι a side view of the shoulder piece gun; the pipe is in the firing position, the locking mechanism is disengaged, FIG. 2 is a section along 2-2 of FIG Seen above, FIG. 3 shows a section corresponding to FIG. 2 with the locking mechanism engaged. Figures 4 and 5 show, on a larger scale, a detail of the locking mechanism in two different positions.

Das Geschützrohr A läuft beim Schuß in der mit ihren wagerechten Schildzapfen c¹ in der Lafette B gelagerten Wiege C zurück und vor. An dieser ist das Schulterstück S befestigt. An der Wiege C ist der eine Teil des Klemmgesperres angeordnet, und zwar besitzt die Wiege hinter dem rechten Schildzapfen c¹ einen Ansatz c², in welchem ein mit einer keilförmigen Klemmnut d¹ versehenes Klemmstück D von prismatischer Gestalt radial zur Achse der Schildzapfen c¹ verschiebbar gelagert ist. Dieses Klemmstück D legt sich gegen einen Bolzen G, der mittels exzentrisch zu seiner Längsachse angeordneter Zapfen g¹, g² in dem Ansätze c² gelagert ist, so daß durch Drehen des Bolzens G das Klemmstück D verschoben werden kann. Der Bolzen G kann mittels eines Hebels H gedreht werden. Das freie Ende dieses mit einem Handgriff versehenen Hebels kann auf einem mit einem Schlitze c³ versehenen Bogen e⁴ gleiten und mittels einer durch den Schlitz reichenden Schraube h¹ am Bogen c⁴ festgestellt werden. Der andere Teil des Klemmgesperres, der Klemmbogen K, ist mittels eines Bolzens b¹ schwingbar an der Lafette B gelagert und greift mit seiner im Querschnitte keilförmigen konvexen Krümmung in die Nut d¹ des Klemmstückes D ein. Die Klemmfiächen des Klemmstückes D und des Klemmbogens K verlaufen konzentrisch zur Achse der Schildzapfen c¹, wenn das Klemmgesperre sich in der Klemmstellung befindet. When fired, the gun barrel A runs back and forth in the cradle C , which is mounted in the mount B with its horizontal trunnion c ^1. The shoulder piece S is attached to this. One part of the locking mechanism is arranged on the cradle C , namely the cradle has a projection c ² ^{behind the right trunnion c 1} , in which a clamping piece D with a wedge-shaped clamping groove d ^{1 is} provided with a prismatic shape radially to the axis of the trunnion c ¹ is slidably mounted. This clamping piece D rests against a bolt G, which is mounted in the lugs c ² by means of pins g ¹ , g ² arranged eccentrically to its longitudinal axis, so that the clamping piece D can be moved by turning the bolt G. The bolt G can be rotated by means of a lever H. The free end of this lever provided with a handle can slide on an arch e ⁴ ^{provided with a slot c 3} and be fixed on arch c ⁴ by means of a screw h ^{1 reaching through the slot.} The other part of the locking mechanism, the clamping arch K, is pivotably mounted on the mount B by means of a bolt b ¹ and engages in the groove d ^{1 of} the clamping piece D with its convex curvature, which is wedge-shaped in cross section. The clamping surfaces of the clamping piece D and the clamping arc K run concentrically to the axis of ^{the trunnion c 1} when the clamping lock is in the clamping position.

Zum Feststellen des Klemmgesperres in der Klemmstellung dienen zwei Klinken E, F. Die eine Klinke, E, ist als Winkelhebel ausgebildet und zwischen zwei an dem Ansätze c² sitzenden, Augen c⁵ gelagert. Die andere Two pawls E, F are used to fix the locking mechanism in the clamping position. One pawl, E, is designed as an angle lever and is mounted between two eyes c ⁵ ^{seated on lugs c 2.} The other

Claims

The pawl, F, is rotatably arranged on two tabs c6 provided directly on the cradle C. Both pawls have noses e1, f1 which can engage with one another. The pawls are connected to one another by a tension spring / in such a way that one pawl takes the other with it when it moves. Opposite the pawls E, F, the cradle C is provided with an opening c1. In ίο this opening protrudes an approach a1 of the gun barrel A, which is provided on the side facing the gun barrel base with an inclined run-up «2, while it is sharply set off on the other side. The approach a1 can work together with the pawls E, F, namely when the gun barrel returns with the pawl E and when moving forward with the pawl F. The arm e2 of the pawl E engages behind the concave curvature of the clamping arch K and can this into the clamping groove Press d1 of clamping piece D. Before the shot, the gun barrel and the locking mechanism are in the position according to FIGS. 1 and 2, in which the clamping bow K loosely engages in the groove d1 of the clamping piece D, so that the gun barrel A can be given the required increase by means of the shoulder piece S . When firing, the gun barrel runs back in the cradle. Immediately after the start of the return movement, the attachment a1 of the gun barrel with its inclined surface «2 rotates the pawl E in the direction of the arrow χ (Fig. 2). Here, the clamping arc K is carried along by the arm e2 of the pawl E and pressed into the groove d1 of the clamping piece D. During the above-mentioned movement of the pawl E, the spring / the pawl F is turned so far until the nose f1 of the pawl occurs behind the nose e1 of the pawl E. In this position (FIG. 3) the locking mechanism is locked and the cradle cannot be rotated about the axis of the trunnion by either a top-down or bottom-up pressure. The height direction given to the gun barrel A before the shot is therefore determined until the locking mechanism is triggered again. This happens immediately before the end of the advance of the gun barrel, in that the shoulder a1 hits the latch -F with its sharply offset end and returns it to its original position (FIG. 2). The movement of the pawl F follows with the intermediary of the spring / the pawl E, so that its arm e1 lifts off the clamping arch and releases it. The cradle and the gun barrel thus regain their mobility relative to the mount. As mentioned above, the clamping piece D can be moved by means of the bolt G in the lugs c2. This device enables the clamping piece D to be readjusted if, after the clamping surfaces have worn out, the contact pressure between the clamping piece D and the clamping arc K is no longer sufficient. By turning the lever H in the direction of the arrow y (FIG. 4), the clamping piece D is brought closer to the clamping arc K, so the contact pressure between them is increased. After loosening the screw h1 and after turning the lever H into the position according to FIG. The clamping piece D will be brought into such a position, for example, if the gun barrel should not advance again to the position in which the projection a1 of the gun barrel disengages the locking mechanism after the shot. In this case, the gun barrel will be lowered so that the gun barrel can advance under the effect of its own weight. ■ Patent claims:
