Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Die vorliegende Erfindung hat den Zweck, Metalle aller Art auf die möglichst schnelle Art bei Anwendung einfacher Werkzeuge glatt und sauber zu zertrennen. Zu diesem Zwecke sind zwei oder mehr Messerköpfe a so angeordnet, dafs dieselben beim Arbeiten gegen einander vorgeschoben werden. In diese Messerköpfe sind die Messer von einfacher Form aus Flachstahl so eingesetzt, dafs zwischen je zwei Messern genügend Platz bleibt, um die Messer des Nachbarkopfes dazwischentreten . zu lassen, so dafs die Messer beim Rotiren der Messerköpfe während des Gegeneinanderarbeitens wie die Zähne eines Zahnrades in einander greifen, jedoch ohne einander zu berühren.The purpose of the present invention is to cut all types of metals smoothly and cleanly in the fastest possible way using simple tools. For this purpose, two or more cutter heads a are arranged in such a way that they are pushed forward towards one another when working. The knives of simple form made of flat steel are inserted into these cutter heads in such a way that there is enough space between each two knives for the knives of the neighboring head to step in between. so that the knives, when the cutter heads rotate while they are working against one another, mesh with one another like the teeth of a gearwheel, but without touching one another.

Durch diese Anordnung wird erreicht, dafs man grofse Querschnitte mit verhältnifsmäfsig kurzen Messern sehr schnell zertrennen kann, da die Messerköpfe gleichzeitig bis über die Mitte des zu zertrennenden Querschnittes arbeiten können; ferner, dafs beim Schadhaftwerden einzelner Zähne das betreffende Messer nachgestellt werden und dafs die Sägespäne leicht herausfallen können.With this arrangement it is achieved that large cross-sections are obtained with relatively large cross-sections can cut short knives very quickly, as the cutter heads simultaneously extend over the middle of the to be able to work cross-section to be cut; furthermore, that when individuals become damaged Teeth the knife in question are readjusted and that the sawdust easily fall out can.

Vorliegende Aenderung unterscheidet sich somit wesentlich von der unter Nr. 34492 patentirten Einrichtung zum Fräsen von Muttern oder Schraubenköpfen, welche zum Zwecke der Anwendung gröfserer Stirnfräser zum Fräsen von kleineren benachbarten Flächen Fräser mit Aussparungen besitzt, welche zahnradartig in einander greifen.The present change therefore differs significantly from that under no. 34492 patented device for milling nuts or screw heads, which for Purpose of using larger face milling cutters for milling smaller neighboring ones Has surface milling cutters with recesses, which mesh with one another like a gear.

Die Messerköpfe a, in welchen die Messer durch Schrauben r nachgestellt werden können, sind in den Schlitten s derart gelagert, dafs dieselben in der Richtung der Spindelachse genau einstellbar sind, damit die Messer stets in derselben Ebene liegen. Dieselben werden durch Riemscheiben g, Schnecken f und Schneckenräder h, welche mit den Messerköpfen fest verbunden sind, in Umdrehung versetzt. Die Schlitten nähern sich während der Arbeit und schreiten so gleichzeitig gegen die Mitte des zu schneidenden Querschnittes vor, was durch das Schaltzeug k I m η ο geschieht, indem die Kurbelscheibe o, welche auf der Schneckenwelle aufgekeilt ist, infolge der Drehung die Zugstange η und mit dieser den Hebel und Schaltkegel m bewegt. Durch Einklinken des letzteren in das Schaltrad / wird die mit Rechts- und Linksgewinde versehene Schraubenspindel k in Umdrehung versetzt und dadurch werden die Schlitten s einander genähert.The cutter heads a, in which the cutters can be readjusted by screws r, are mounted in the carriage s in such a way that they can be precisely adjusted in the direction of the spindle axis so that the cutters always lie in the same plane. The same are set in rotation by pulleys g, worms f and worm wheels h, which are firmly connected to the cutter heads. The carriages approach during the work and thus simultaneously advance towards the center of the cross-section to be cut, which is done by the switching tool k I m η ο by the crank disk o, which is keyed on the worm shaft, the pull rod η and as a result of the rotation with this the lever and switching cone m moved. By engaging the latter in the ratchet wheel / the screw spindle k , which is provided with right and left-hand threads, is set in rotation and thereby the carriages s are brought closer to one another.

Durch das Ineinandergreifen der Sägemesser wird erreicht, dafs dieselben möglichst kurz gehalten werden können, wodurch einem Abweichen derselben vorgebeugt und ein sauberer gerader Schnitt garantirt wird. Das Werkstück wird durch einen Parallelschraubstock sicher in der Mitte zwischen den Messerköpfen gehalten.The interlocking of the saw blades ensures that they are as short as possible can be held, thereby preventing them from deviating and making them cleaner straight cut is guaranteed. The workpiece is secured by a parallel vice held in the middle between the cutter heads.
