Description

KAISERLICHESIMPERIAL

PATENTAMTPATENT OFFICE

Die in beiliegender Zeichnung und Beschreibung dargestellte Gewindeschneidkluppe besteht aus einem Kranze a mit aufgeschraubtem Deckel, welch letzterer die beiden Backen b fest in den Kranz einspannt, während die dritte Backe c mit Hülfe des Knopfes d verschoben werden kann. Bei nach innen geschobenen Backen c stöfst derselbe mit einem Ansatz an die Schraube e an und wird in dieser Lage durch die Klemmschraube f befestigt, worauf das Schneiden des Gewindes beginnen kann. Das Zurückschieben der Backe c und der Schraube f wird durch eine schräge Fläche g verhindert, an welcher der ebenfalls schräge Kopf der Klemmschraube f gut angepafst ist.The thread cutting stock shown in the accompanying drawing and description consists of a ring a with a screwed-on cover, which the latter clamps the two jaws b firmly in the ring, while the third jaw c can be moved with the aid of button d . When the jaws c is pushed inwards, the latter abuts the screw e with a shoulder and is fastened in this position by the clamping screw f , whereupon the thread cutting can begin. The sliding back of the jaw c and the screw f is prevented by an inclined surface g to which the likewise inclined head of the clamping screw f is well adapted.

Das Abheben der Kluppe erfolgt nach Lösen der Klemmschraube, f und Zurückdrücken der beweglichen Backe c. Der einen Backe b diametral entgegengesetzt ist eine vierte Backe h angebracht, welche auf ihrer ganzen Breite gleiches Gewinde hat und durch Einstellen mittelst der Stellschraube i das Schraubengewinde bis an das untere Ende ganz ausschneidet, so dafs die Mutter bis an das Ende des Gewindes aufgeschraubt werden kann.The clip is lifted off after loosening the clamping screw, f and pushing back the movable jaw c. A fourth jaw h is attached diametrically opposite to one jaw b , which has the same thread over its entire width and, by adjusting it by means of the adjusting screw i , cuts out the screw thread all the way to the lower end, so that the nut can be screwed on to the end of the thread can.

Die bisher verwendeten Kluppen, mit denen man auf einmal das Ausschneiden eines Gewindes bewirken konnte, hatten zwei oder drei verstellbare Backen und waren daher sehr complicirt und nur bei sorgfältigster Ausführung mit Vortheil zu verwenden, hatten aber alle noch aufserdem den Uebelstand, dafs das Gewinde am unteren Ende nicht ausgeschnitten war und die Mutter daher nicht ganz aufgeschraubt werden konnte.The previously used clips, with which you can cut out a thread at once had two or three adjustable jaws, and were therefore very complicated and to be used with advantage only if carried out with the greatest care, but all had there was also the disadvantage that the thread at the lower end was not cut out and the nut could therefore not be screwed all the way open.
