Patentirt im Deutschen Reiche vom 7. Februar i8go ab.Patented in the German Empire from February 7th, 1860.

Bei körnigen, klebrigen und ähnlichen Stoffen, z. B. Cellulose, Biertreber, Braunkohle, Getreide, Dicksaft, Melasse u. dergl. hat es sich als höchst nachtheilig erwiesen, dafs sämmtliche bis jetzt bekannten Schieber durch das unvermeidliche Abheben der Platte vom Sitz während des Hubes durch zwischentretende Theilchen die erwünschte Dichtung nicht erreichen lassen. Der dargestellte Schieber soll diesem Uebelstande abhelfen.In the case of granular, sticky and similar substances, e.g. B. cellulose, spent grains, lignite, grain, Thick juice, molasses, and the like, it has been found to be extremely detrimental that all of them until now known slide by the inevitable lifting of the plate from the seat failing to achieve the desired seal during the stroke due to intervening particles permit. The slide shown is intended to remedy this problem.

In dem Schiebergehäuse a, Fig. 1 bis 9, befindet sich die Schieberplatte b und die Spindel c, durch welche der Schieber geöffnet und geschlossen werden kann. Um das Abheben der Schieberplatte b von ihrem Sitz zu verhindern, wirkt das Gewicht d des Hebels e auf die kleinen, im Gehäuse befindlichen Hebel / in der Weise, dafs der Bolzen g mit einem oder mehreren Druckhebeln h gegen die Schieberplatte geprefst wird. Wird durch die Spindel c der Schieber geöffnet, so wird der Punkt g und dadurch das Gewicht d gehoben, aber die Schieberplatte wird während des ganzen Hubes an die Sitzfläche geprefst, und alle Theilchen, welche auf die Dichtungsflächen fallen, werden während des Hubes bei Seite geschoben und dadurch die Dichtungsflächen vollkommen sauber erhalten. Auch schleift sich der Schieber während des Betriebes immer selbstthätig nach.The slide plate b and the spindle c, through which the slide can be opened and closed, are located in the slide housing a, FIGS. 1 to 9. In order to prevent the slide plate b from lifting off from its seat, the weight d of the lever e acts on the small levers in the housing / in such a way that the bolt g is pressed against the slide plate with one or more pressure levers h. If the slide is opened by the spindle c , the point g and thereby the weight d is raised, but the slide plate is pressed against the seat surface during the entire stroke, and all particles which fall on the sealing surface are aside during the stroke pushed and thereby keep the sealing surfaces completely clean. The slide also always grinds itself automatically during operation.

Fig. 8 und 9 stellen einen Schieber aus säure-( beständigem (verbleitem) Stoff dar., Hier wird ' der Druck auf den Schieber dadurch erzielt, dafs sich in dem mit der Welle i schwingenden Cylinder k ein Kolben / bewegt, welcher nach innen abgedichtet ist. Auf diesen Kolben wirkt durch die Leitung η Wasser-, Luftoder anderer Druck, prefst die Kugel ο während des ganzen Hubes gegen den Rücken des Schiebers und dadurch diesen selbst gegen die Dichtungsflächen, wodurch auch hier ein Abheben der Schieberplatte von ihrem Sitz während ihres ganzen Hubes unmöglich wird. Die Schraube ρ ist angeordnet, um von Zeit zu Zeit unter Abnahme des Deckels q Schmierstoff für den Kolben / einführen zu können. Während die Schieberplatte behufs Oeffnens zurückgezogen wird, tritt der Kolben / unter dem durch die Leitung η auf ihn wirkenden Druck in den Cylinder zurück, um bei geöffnetem Schieber wieder in die erste (punktirte) Lage herauszutreten.8 and 9 show a slide made of acid ( resistant (leaded) material. 'Here the pressure on the slide is achieved by a piston / moving inwards in the cylinder k oscillating with the shaft i On this piston acts through the line η water, air or other pressure, the ball prefstst ο during the entire stroke against the back of the slide and thereby this itself against the sealing surfaces, whereby a lifting of the slide plate from its seat during The screw ρ is arranged to be able to introduce lubricant for the piston / from time to time by removing the cover q . While the slide plate is pulled back to open it, the piston / occurs under the through the line η pressure acting on it back into the cylinder, in order to step out again into the first (punctured) position when the slide is open.

Zum besseren Wegschieben von Unreinigkeiten, welche sich auf dem freien Sitz abgelagert haben, sind die Kanten der Schieberplatte abgeschrägt.For better pushing away impurities that are deposited on the free seat the edges of the valve plate are beveled.
