Landmine. Patentiert im Deutschen Reiche vom 30. Mai 1914 ab. Land mine. Patented in the German Empire on May 30 , 1914.

Es sind zahlreiche Einrichtungen von Landminen bekannt; z. B. gelangt eine große, in der Erde verborgene Sprengladung durch direkte Kraftäußerung des Sprengstoffes zur Wirkung. Bei anderen Einrichtungen wird eine in der Erde oder darüber angebrachte Mine mit vorbereiteten Sprengstücken zur Explosion gebracht und besonders auf die Sprengstückwirkung gerechnet. Von solchen Minen seienNumerous landmine installations are known; z. B. gets a large, in Explosive charge hidden from the earth through direct expression of the force of the explosive to take effect. At other facilities, a mine installed in the ground or above with prepared explosives explodes brought and especially counted on the effect of the explosive. Be from such mines

ίο hier angeführt die sogenannten Steinminen, bei denen eine unter dem Erdboden angeordnete Steinladung in einer allgemeinen Richtung nach vorwärts zu herausgeschleudert wird. Diese Minen besitzen den Nachteil, daß die Flugbahn der Sprengteile keine rasante sein kann, da zum Herausschleudern aus dem Erdboden Erhöhungen der Mine von etwa 60 ° erforderlich sind (vgl. Bruno Zschokke, Handbuch der gesamten militärischen Sprengtechnik, Leipzig 1911, S. 265, Fig. 184). Minen, bei. denen ganze Geschosse aus dem Erdboden herausgeschleudert werden, besitzen den Nachteil, daß die über dem Erdboden platzenden Geschosse ihre Wirkung auch nach rückwärts auf den Verteidiger hin zur Geltung bringen. Denselben Nachteil besitzen auch die bekannten sogenannten Landtorpedos, z. B. nach dem System Pfund-Schmidt (a. a. 0., S.271U. f.). Diesen Ubelständen soll die hier beschriebene neue Mineneinrichtung abhelfen.ίο here mentioned the so-called stone mines, in which a stone load placed underground in a general direction being thrown forward to. These mines have the disadvantage that the The trajectory of the explosive parts cannot be rapid, as it is thrown out of the ground Elevations of the mine of about 60 ° are required (cf. Bruno Zschokke, Handbook of the entire military blasting technology, Leipzig 1911, p. 265, Fig. 184). Mines, at. whole projectiles are thrown out of the ground, have the disadvantage, that the projectiles bursting above the ground also bring their effect backwards towards the defender. The well-known so-called land torpedoes, e.g. B. after the Pfund-Schmidt system (op. Cit., P.271U. F.). The one described here is intended to counteract these evils remedy new mine facility.

Sie ist gekennzeichnet durch das gleichzeitige Zusammenwirken einer Hauptsprengladung und einer oder mehrerer Backenladungen. Die brisante Hauptsprengladung bewirkt ein rasantes Fortschleudern der vorgelagerten Sprengteile nahe über dem Erdboden hin. Die vorgesehenen Backenladungen, die sowohl als Seitenladung, Deckelladung, oder nach Bedarf auch als Bodenladung Verwendung finden können, detonieren gleichzeitig mit der Haupt-Sprengladung. Die von ihnen erzeugten hochgespannten Detonationsgase üben von der Seite her, auf welcher die Backenladung angeordnet war, einen entsprechenden Seitendruck auf die Sprengstückgarbe während'ihres Entstehens aus. Es wird damit einer zu großen seitlichen Ausbreitung der Sprengstückgarbe durch die Hauptladung entgegengetreten. Die Sprengstückgarbe wird infolgedessen mehr in einer bestimmten Richtung zwangläufig weitergeleitet, als es sonst bei dem Bestreben der hochgespannten Gase der Hauptladung, sich nach allen Seiten hin auszubreiten, der Fall ist. Gleichzeitig wird durch die Anordnung der Hauptladung hinter einer Sprengstückwand im Verein mit den Backenladungen dafür gesorgt, daß nach rückwärts in Richtung auf den Verteidiger zu nahezu gar keine Sprengstücke zurückfliegen, daß also hinter der Mine bereits in geringer Entfernung von ihr eine große Sicherheitszone gebildet wird. Die beim Sprengen entstehenden Splitter des Minenkastens sind nur klein und werden nur auf geringe Entfernung hin nach rückwärts noch wirksam. Über diese Abstände hinaus muß die Mine ohnehin vor die Verteidigungslinie vorgeschoben werden, um den Verteidiger nicht durch Knall und Luftdruckwirkung zu gefährden.It is characterized by the simultaneous interaction of a main explosive charge and one or more jaw loads. The explosive main explosive charge causes a rapid hurling of the upstream one Explosive parts close to the ground. The intended jaw loads, which are both Side loading, top loading or, if required, also bottom loading can be used, detonate at the same time as the main explosive charge. The high tension ones they created Detonation gases exert a corresponding side pressure from the side on which the jaw charge was arranged on the sheaf of explosives while it is being created. It becomes one with it large lateral spread of the fragmentation sheaf countered by the main charge. As a result, the sheaf of fragments becomes more inevitable in a certain direction forwarded than is otherwise the case with the high-tension gases of the main charge, spreading in all directions is the case. At the same time, through the arrangement of the main charge behind a demolition wall in conjunction with the cheek charges ensured that backwards in Direction towards the defender to fly back almost no explosives, so that a large safety zone was formed behind the mine at a short distance from it will. The fragments of the mine box that are created during blasting are only small and only become effective at a short distance backwards. About these distances the mine must be pushed in front of the defensive line anyway in order to avoid the Not to endanger defenders by bang and the effects of air pressure.

not included as bottom cargo, as the mine is raised on a block of wood. In this way it is achieved in the present embodiment that explosives are not get bogged down in the ground. A jaw load as a bottom load can be used with other arrangement of the mine, e.g. B. Elimination of the block of wood, as a base for the mine of Be an advantage.

The use of such mines is as follows: The box-like mine vessel is placed on the ground and covered accordingly. The mines can also be buried in the ground. A special, suitable device, not described here, is then initially used to raise it above the ground before the mine charge detonates. Incidentally, such lifting does not take place, as is the case with other known mining devices, by the explosion of a propellant charge acting directly on the mine box, since this would necessarily damage the structure of the mine box.
From known mining facilities, e.g. B.

that described by the American patent 811048 differs present by the inevitable leadership of the explosive parts in certain directions there. The American facility attracted by a special propellant charge first of all a lifting of the projectile from the ground up to above the surface of the earth instead, and then an ejection of special sub-floors from the main floor. Here the effect of the it shot in all directions, while in the case of the mine installation at hand it was the Regulation of the explosive distribution in very specific directions is achieved. Further the device according to the American patent specification is required that the Shooting out of the sub-floors from the main floor must take place later, when the bottom charge of the projectile exploded. This is achieved by that a propellant charge of relatively mild explosive to raise the Main floor is used, after which the partial floors are only shot out a mild propellant charge takes place from the main floor. These moments are quite different from the present device in that there are no propellant charges, but explosive charges that are currently shattering and have an effect which are separated into main and cheek charges, but directly with one another are connected and also have an effect at the same time.

85 P α τ ε ν τ claim:

Landmine, characterized by one behind a demolition wall in one box-like container arranged detonating main charge, with which at the same time one or more jaw charges detonated as a top, side or bottom charge, causing a rapid Hurling of the explosives in certain directions with limited spread to that by the jaw charge limited sides takes place, and thereby backwards on the defender to keep a large safety zone free of explosives at a short distance from the mine.
