KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Das in beiliegender Zeichnung dargestellte Vier-Walzwerk hat folgende Anordnung: Die Walzenpaare haben ungleichen Durchmesser, liegen nicht in einer Ebene und greifen nicht keilförmig in einander.The four-roller mill shown in the accompanying drawing has the following arrangement: The Pairs of rollers have different diameters, are not in one plane and do not grip wedge-shaped in each other.

Das grofse senkrecht angebrachte Walzenpaar w und w'1 Fig. 1, 2 und 3, erfafst das weifsglühende Eisen r zuerst und walzt es auf die dem zu formenden Gegenstand entsprechende Dicke (die Zeichnung zeigt einen Normal-Eisenbahnschienennagel n, Fig. 2, 3, 4 und 5), wobei die erforderlichen Erhöhungen durch die Vertiefung a, auf der Peripherie der Walzen angebracht, erzeugt werden.The large vertically mounted pair of rollers w and w'1, Fig. 1, 2 and 3, grabs the white-hot iron r first and rolls it to the thickness corresponding to the object to be formed (the drawing shows a normal rail nail n, Fig. 2, 3 , 4 and 5), the necessary elevations being produced by the recess a, made on the periphery of the rollers.

Das kleinere, waagrecht angebrachte Walzenpaar w" und w'" erfafst das Eisen erst dann, nachdem es die Walzen w und n>' zu der gehörigen Dicke gebracht, um seinerseits durch die Erhöhungen c und Vertiefungen b dem Nagel die Nase und Spitze anzuwalzen.The smaller, horizontally attached pair of rollers w " and w '" grips the iron only after it has brought the rollers w and n>' to the appropriate thickness, in order to roll the nose and point of the nail through the protrusions c and depressions b.

Der Erfinder hat im wesentlichen auf das Lagern in zwei Ebenen, sowie auf den ungleichen Durchmesser der Walzenpaare w und w' und n>" und w'" Bedacht genommen, um zwischen den Walzen das Hervorquellen des glühenden Eisens zu verhüten, welches bei anderen Systemen erst durch besondere Vorrichtungen erreicht werden kann. Derselbe hat daher ein Walzwerk geschaffen, welches nicht nur für fajonnirtes Eisen in Längs- und Querrichtung, sondern auch gleich gut für Flach- und Vierkanteisen zu verwenden ist.The inventor has essentially taken into account the storage in two planes, as well as the unequal diameter of the roller pairs w and w ' and n>" and w'" in order to prevent the glowing iron from swelling out between the rollers, which is the case with other systems can only be achieved through special devices. He has therefore created a rolling mill which can be used not only for faced iron in the longitudinal and transverse direction, but also equally well for flat and square iron.

Das Walzwerk wird mittelst Riemen auf Scheiben S1 S angetrieben, welche durch Welle C mit dem Trieb T verbunden sind. Letzteres ist mit dem Zahnrade A auf der die Walze w tragenden Welle D im Eingriff. Die Walze w ist durch die Räder V und V mit der Walze w' verbunden. Die Walzen w" und n>'" werden durch die Kegelräder K und K von der Walze w bewegt.The rolling mill is driven by means of belts on pulleys S 1 S , which are connected to drive T by shaft C. The latter is in engagement with the gear wheel A on the shaft D carrying the roller w. The roller w is connected to the roller w ' by the wheels V and V. The rollers w " and n>'" are moved by the bevel gears K and K of the roller w .

Die Wellen der zwei Walzenpaare laufen in Lagern L und L ', welche an dem Rahmen R mit Fufsplatte F mittelst Schrauben s festgehalten und mittelst Stellschrauben s' gestellt werden können, Fig. 1, 2 und 3.The shafts of the two pairs of rollers run in bearings L and L ', which can be held on the frame R with footplate F by means of screws s and adjusted by means of adjusting screws s' , Figs. 1, 2 and 3.

Das weifsglühende Eisen wird, wie aus Fig. 2 und 3 bei h zu ersehen ist, in die Walzen hineingeführt und, wie schon oben erwähnt, zuerst von den grofsen Walzen erfafst und gewalzt. Die kleinen Walzen, um den Zwischenraum ^, Fig. 2 und 3, zurückgelagert, arbeiten eingeschlossen und bringen den fertigen Gegenstand in die Führung G, Fig. 2, 3 und 4, um demselben eine gerade Richtung zu geben. The white-hot iron, as can be seen at h in Figs. 2 and 3, is fed into the rollers and, as already mentioned above, is first grasped and rolled by the large rollers. The small rollers, placed back around the gap ^, Fig. 2 and 3, work locked and bring the finished object into the guide G, Fig. 2, 3 and 4, in order to give it a straight direction.
