Patentirt im Deutschen Reiche vom 17. Februar 1882 ab.Patented in the German Empire on February 17, 1882.
Das Bewegen der Pressen geschieht durch hydraulischen Druck und durch Vacuum. Der hydraulische Druck kommt beim Bewegen der Pressen nach der Richtung des Steines, beim Anpressen des Stoffes, in Anwendung; durch das Vacuum werden die Pressen zurückgefahren. α α α sind die Kästen zum Aufnehmen des Holzes. Jeder derselben hat auf seinem Verschlufsdeckel eine kleine hydraulische Presse, deren Kolben mit der Prefsplatte verbunden ist.The presses are moved by hydraulic pressure and vacuum. The hydraulic pressure is used when moving the presses in the direction of the stone, when pressing the fabric; the presses are retracted by the vacuum. α α α are the boxes to hold the wood. Each of these has a small hydraulic press on its closure cover, the piston of which is connected to the Prefsplatte.
'Der hydraulische Druck, welcher je nach Erfordernifs und disponibler Kraft zum Schleifen zwischen 10 und 20 Atmosphären schwankt, wird durch die. Prefspumpe, Fig. 4, erzeugt. Das Wasser drückt zunächst einen Accumulator, Fig. 5, in die Höhe, welcher durch Wasseranfüllung auf den erforderlichen Widerstand von 10 bis 20 Atmosphären belastet wird. Von demselben wird der Druck den drei Prefspaaren zugeführt.'The hydraulic pressure, which depends on the requirements and available power for grinding fluctuates between 10 and 20 atmospheres, is through the. Pref pump, Fig. 4, is generated. The water first presses an accumulator, Fig. 5, in height, which by filling with water to the required resistance of 10 to 20 atmospheres is loaded. The same applies to the pressure on the three pairs of prefers fed.
Die Druckhähne b 6 b vertheilen den Wasserdruck zu je zwei Pressen, so dafs derselbe auf jedes gegenüberstehende Paar vollkommen gleichmäfsig erfolgt. Die Hähne c c c sind Ablafshähne, welche durch Röhren mit dem Kessel einer Vacuumpumpe, Fig. 6, in Verbindung stehen.The pressure taps b 6 b distribute the water pressure to two presses each, so that the same occurs perfectly evenly on each opposing pair. The taps ccc are drain taps which are connected to the tank of a vacuum pump, FIG. 6, by means of tubes.
Die Hebel dieser Hähne c sind mit den Hebeln der Druckhähne b derart verbunden, dafs beim Schliefsen der einen die anderen geöffnet werden; sobald man also einen Druckhahn b schliefst, sind die hydraulischen Pressen mit dem Vacuum verbunden, die Prefsplatte geht sofort zurück und der Kasten kann frisch gefüllt werden.The levers of these taps c are connected to the levers of the pressure taps b in such a way that when one closes the other opens; As soon as a pressure tap b is closed , the hydraulic presses are connected to the vacuum, the prefilling plate goes back immediately and the box can be freshly filled.
