Patentirt im Deutschen Reiche vom l. December 1882 ab.Patented in the German Empire from l. December 1882.
Wenn beim Aufgang des Messerschlittens a derselbe in der Nähe seines höchsten Hubes angekommen ist, stöfst der an demselben befestigte, mit Rolle versehene Stift b an den Hebel c an und hebt denselben bis zum Endpunkt des Schlittenhubes mit in die Höhe. Genannter Hebel hat in d seinen Drehpunkt und ist aus zwei Schienen gebildet, welche die Zapfen e eines auf der Spindel f zwischen zwei Ringen g drehbar sitzenden Kreuzkopfes umfassen. Die mit Handrad h versehene Spindel/ wird so beim Hub des Hebels c mit in die Höhe genommen und also auch der Prefsballen 2, in dessen eingeschnittenem Gewinde die Spindel / eingreift. Das Handrad h dient zum Höher- und Tieferstellen des Prefsbalkens je nach der Dicke der Papierstöfse. Einmal gestellt, wird diese Stellung für eine gröfsere Anzahl gleich dicker Papierstöfse, Bücher etc. nicht mehr verändert.Has arrived when at the rising of the knife carriage a same highest in the vicinity of its stroke, the stöfst attached to the same and provided with rolling pin to the lever b c and raises the same to the end point of the slide elevation, with the height. Said lever has its fulcrum in d and is formed from two rails which enclose the pins e of a cross head rotatably seated on the spindle f between two rings g. The spindle / provided with the handwheel h is taken up with the stroke of the lever c , and so is the prefsballen 2, in whose thread the spindle / engages. The handwheel h is used to raise and lower the pref beam depending on the thickness of the paper stems. Once set, this position is no longer changed for a larger number of equally thick paper pods, books, etc.
Die an dem Ende des Hebels c angehängte Stange k ist ebenfalls gehoben worden und hierdurch auch der untere, um / drehbare Hebel m sammt dem darauf sitzenden Gewicht n. Beim Abgang des Messerschlittens geht auch der Prefsbalken, dessen untere Fläche der Messerschneide immer ein Stück voraus ist, herunter und gelangt alsbald auf das Papier, wo er durch das Gewicht η vermittelst des beschriebenen Mechanismus fest geprefst wird, während das Messer weitergeht und den Schnitt durch das Papier ausführt.The rod k attached to the end of the lever c has also been lifted and thereby also the lower, rotatable lever m together with the weight n sitting on it. When the knife carriage leaves, the prefab bar, the lower surface of which is always a little ahead of the knife edge is, down and immediately reaches the paper, where it is firmly pressed by the weight η by means of the mechanism described, while the knife continues and makes the cut through the paper.
Der Stift 0, auf welchem sich der Hebel m nach Vollendung der Pressung auflegen kann, ist in der Höhe verstellbar angebracht, so dafs hierdurch der Hub des Prefsbalkens gröfser oder kleiner gemacht werden kann, je nachdem das Papier, welches geschnitten werden soll, weich oder hart ist.The pin 0, on which the lever m can rest after completion of the pressing, is mounted adjustable in height, so that the stroke of the pref beam can be made larger or smaller, depending on the paper that is to be cut, soft or is tough.
