Kläss6'49r-Class 6'49r-

FRANZ LAFERL in WIEN.
Gewindeschneidkluppe.
FRANZ LAFERL in VIENNA.
Thread cutting stock.

Patentirt im Deutschen Reiche vom ii. Juli 1878 ab.Patented in the German Empire from ii. July 1878 onwards.

Diese Schneidkluppe besteht, wie beiliegende Zeichnung zeigt, ihrer Wesenheit nach aus einem runden Gehäuse A mit zwei Armen B B-aus Schmiedeisen oder Bessemerstahl. In diesem Gehäuse bewegen sich wie bei dem amerikanischen Klemmfutter (Spiralfutter) vier Backen C in entsprechenden Nuthen. Diese vier Backen werden durch die in dem Ringe D befindliche Spirale bei jeder Drehung des Ringes in derselben Weise wie bei den angeführten Spiralfuttern zu gleicher Zeit central verschoben.This cutting stock consists, as the accompanying drawing shows, essentially of a round housing A with two arms B- made of wrought iron or Bessemerstahl. In this housing, as with the American clamping chuck (spiral chuck), four jaws C move in corresponding grooves. These four jaws are moved centrally by the spiral located in the ring D with each rotation of the ring in the same way as in the case of the spiral chucks mentioned at the same time.

Die Drehung des Ringes D mit seiner Spirale erfolgt hier durch ein seitlich angebrachtes Getriebe F, welches in die Zähne des als Stirnrad verzahnten Ringes eingreift und durch einen Schlüssel umgedreht wird. Das ganze bewegliche System wird durch den Ring g, welcher in den Ring Ό falzartig eingelassen und mittelst vier Schrauben mit versenkten Köpfen mit dem Gehäuse A verbunden ist, in letzterem drehbar befestigt und zusammengehalten.The rotation of the ring D with its spiral takes place here by a laterally attached gear F, which engages in the teeth of the ring, which is toothed as a spur gear, and is turned by a key. The whole movable system is rotatably fastened and held together in the latter by the ring g, which is let into the ring Ό like a fold and is connected to the housing A by means of four screws with countersunk heads.

Die eigentlichen Schneidbacken e sind in die vorerwähnten beweglichen Backen C so eingesetzt, dafs dieselben mittelst daran befindlicher Zäpfchen und in letzteren eingefräster Nuthen ganz unbeweglich darin sitzen und von rückwärts durch das Loch H, von welchem die Backen / ganz durchbohrt sind, mittelst eines Stiftes leicht wieder herausgeschlagen werden können.The actual cutting jaws e are inserted into the aforementioned movable jaws C in such a way that they sit immovably in them by means of cones located on them and grooves milled in the latter, and easily by means of a pin from behind through the hole H, through which the jaws / are completely pierced can be knocked out again.

Durch diese Construction ist man im Stande, das eigentliche Messer oder Schneidwerkzeug zum Gewindeschneiden in der einfachsten Form und mit dem geringsten Aufwand an Gufsstahl zu erzeugen und dem Arbeiter sowohl das Nachschleifen der Backen wie die gänzliche Erneuerung derselben sehr leicht zu machen, was bei anderen dergleichen Werkzeugen gewöhnlich umständlicher und kostspieliger zu bewerkstelligen ist.Through this construction one is able to use the actual knife or cutting tool for thread cutting in the simplest form and with the least amount of effort to produce cast steel and the worker both the regrinding of the jaws as well as the complete renewal of the same are very easy do what is usually more cumbersome and expensive with other such tools is to be accomplished.

Ein weiterer Vortheil dieser Schneidbacken besteht nach dem Erfinder darin, dafs dieselben niemals quetschen, sondern gleichwie die Seiler' sehen Schraubenschneidemaschinen-Backen nur schneiden, daher z. B. den Gewindeausschnitt bei Gasrohren nicht oval drücken.According to the inventor, a further advantage of these cutting jaws is that they never squeeze, but just like the Seiler see screw cutting machine jaws just cut, therefore z. B. Do not press the thread cutout oval in gas pipes.
