KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Um die Herstellung enggelochter Mauerziegel in zweckmäßiger Weise auszuführen, sind die an sich bekannten, in das Mundstück der Ziegelpresse hineinragenden Lochdorne gemäß der Erfindung an dünnen Bändern aus Flachstahl oder an Doppeldrähten befestigt, die so in den Kastenrahmen eingelassen sind, daß sie mittels einer an dem einen Ende befindlichen Spannvorrichtung zu jeder Zeit straff gespanntIn order to carry out the production of tightly perforated masonry bricks in an expedient manner, the known per se, protruding into the mouthpiece of the brick press piercing mandrels according to the invention attached to thin strips of flat steel or to double wires, which are embedded in the box frame that they mean a jig located at one end taut at all times

ίο werden können. Auf diese Weise wird erreicht, daß dem Tonstrang ein möglichst geringer, auf den ganzen Querschnitt des Mundstückes sehr gleichmäßig verteilter Widerstand entgegengesetzt wird, der dem gleichmäßigen Verteilen und Verdichten der Tonmasse sehr günstig ist.ίο can be. In this way it is achieved that the clay strand is as small as possible over the entire cross-section of the mouthpiece very evenly distributed resistance is opposed to the even Distributing and compacting the clay mass is very beneficial.

Fig. ι zeigt in schematischer Darstellung die Rückansicht eines mit dem Erfindungsgegenstand versehenen Mundstückes, während dieFig. Ι shows a schematic representation the rear view of a mouthpiece provided with the subject matter of the invention, while the

Fig. 2 und 3 Querschnitte durch das Mundstück mit zwei verschiedenen Ausführungsformen der Lochdornbefestigung wiedergeben. Um eine Schwächung der dünnen Spannbänder B möglichst zu vermeiden, erfolgt die Befestigung der Dorne D an ihnen am besten mittels Festklemmens. Das Festklemmen der Dorne wiederum erfolgt zweckmäßig mittels Klemmschrauben S1, die die geschlitzten Enden zusammenpressen.Fig. 2 and 3 show cross sections through the mouthpiece with two different embodiments of the piercer attachment. In order to avoid a weakening of the thin tensioning straps B as far as possible, the attachment of the mandrels D to them is best done by means of clamping. The mandrels are, in turn, suitably clamped by means of clamping screws S 1 , which press the slotted ends together.

Bei der Anwendung eines doppelten Drahtes als Spannband B (Fig. 3) können mittels der Klötzchen K auch zwei Bänder auf einmal gespannt werden.When using a double wire as a tensioning band B (Fig. 3), two bands can be tensioned at once by means of the blocks K.

Es läßt diese Vorrichtung eine Lochung der Steine zu, bei welcher die Löcher in großer Anzahl dicht nebeneinander liegen, und diese Steine zeigen trotzdem eine gleichmäßige Struktur und haben infolge der großen Anzahl der Lochungen den Vorteil, bei der Verwendung die Lagerfuge sehr dicht und fest zu verkrallen, das Einfallen von Fugenmörtel zu verhindern und stark isolierend zu wirken.It allows this device to perforate the stones, in which the holes in large Number are close together, and these stones still show an even Structure and have the advantage of using them due to the large number of perforations to claw the bed joint very tightly and firmly, to prevent the penetration of joint mortar prevent and have a strong insulating effect.

Es sind daher solche Ziegel besonders dort mit Vorteil zu verwenden, wo es gilt, schon bei geringer Wandstärke eine große Undurchlässigkeit gegen Feuchtigkeit, Wärme oder Kälte zu erzielen, wie dies z. B. beim Bau von Schornsteinen u. dgl. der Fall ist.It is therefore particularly advantageous to use such bricks where it is necessary with a small wall thickness a high impermeability to moisture, heat or To achieve coldness, as z. B. in the construction of chimneys and the like. Is the case.

Natürlich kann diese Vorrichtung bei Ziegeln jedweder Fonn, wie z. B. bei Radialsteinen, Verblendern u. dgl., zur Anwendung kommen.Of course, this device can be used with bricks any form, such as B. in radial stones, facing bricks and the like., For use come.
