C. J. FR. NEUBER & J. C. J. VERNIMB in HAMBURG. Mit Rohrabschneider combinirte Rohrkluppe mit eiiiptischen Schneidbacken.C. J. FR. NEUBER & J. C. J. VERNIMB in HAMBURG. Pipe clip combined with pipe cutter with oval cutting jaws.

Patentirt im Deutschen Reiche vom 5· August 1877 ab.Patented in the German Empire on August 5, 1877.

Das vorliegende Instrument ermöglicht Schraubengewinde von gleicher Steigung an Rohren verschiedenen Durchmessers mit denselben Backen zu schneiden, und nach Beendigung dieser Arbeit das Rohr mit demselben Instrument abzuschneiden.The present instrument enables screw threads of the same pitch on pipes different diameters to cut with the same jaws, and after finishing cut the pipe with the same instrument during this work.

Die Schneidbacken erhalten zu diesem Zweck einen elliptischen Querschnitt, so dafs für Rohre verschiedenen Durchmessers, verschiedene Stellen der Schneidbacke in Thätigkeit treten.For this purpose, the cutting jaws have an elliptical cross-section, so that for pipes different diameters, different places of the cutting jaw come into action.

Die Construction dieser Schneidkluppe ist in der beiliegenden Zeichnung in zwei verschiedenen Gröfsen veranschaulicht. Fig. 1 stellt eine Seitenansicht, Fig. 2 einen Längsschnitt, Fig. 3 eine obere Ansicht, Fig. 4 einen Schnitt nach A B, und Fig. 5 einen Schnitt nach CD der für Rohre gröfseren Durchmessers bestimmten Kluppe dar, während Fig. 6 eine Seitenansicht, Fig. 7 einen Schnitt nach EF und Fig. 8 eine Ansicht der Schneidbacke einer kleineren Kluppe zeigt.The construction of this cutting stock is illustrated in the accompanying drawing in two different sizes. 1 shows a side view, FIG. 2 shows a longitudinal section, FIG. 3 shows a top view, FIG. 4 shows a section according to AB, and FIG. 5 shows a section according to CD of the clip intended for pipes of larger diameter, while FIG Side view, FIG. 7 shows a section according to EF and FIG. 8 shows a view of the cutting jaw of a smaller clip.

Bei der ersten Modification ist die Kluppe zweiarmig, bei der zweiten blos einarmig eingerichtet. Von den beiden Schneidbacken α und b ist erstere mittelst zweier Schrauben cc in dem gebogenen Theil des Stückes d befestigt, letztere in einem ■ Support /, welcher sich in einem Schlitz des Stückes d führt. Bei der gröfseren Kluppe ist an die Backe α zugleich der zweite zum Handhaben dienende Griff g geschraubt.. Die Backe b ist schwalbenschwanzförmig in den verstellbaren Support / eingelassen und wird durch' eine Druckschraube i fixirt. Die Verschiebung des Supports / erfolgt durch die Schraube k, welche in ihrer Verlängerung zugleich den Handgriff kx bildet.In the first modification, the clip is set up with two arms, with the second one only with one arm. Of the two cutting jaws α and b , the former is fastened by means of two screws cc in the curved part of the piece d, the latter in a support / which is guided in a slot in the piece d . In the case of the larger clip, the second handle g, which is used for handling, is screwed to the jaw α at the same time. The jaw b is dovetail-shaped in the adjustable support / and is fixed by a pressure screw i. The support / is shifted by the screw k, which in its extension also forms the handle k x.

Die an dem Vierkant befindlichen vier Löcher k2 dienen zum Einstecken eines Dorns behufs Drehung der Schraubenspindel k. Diese ist mittelst eines kugelförmigen Kopfes / in einer entsprechenden Ausbohrung des Supports / gelagert. Der cylindrische Stift 77Z1 dient als Lagerdeckel; derselbe ist an der Platte m befestigt, welche mittelst der Schraube η mit dem Support / verbunden ist und eine gleichmäfsige Führung des Supports / bewirkt. Andererseits führt sich- letzterer mittelst des unteren Theiles seines runden Schaftes /i- in einer entsprechenden Aushöhlung des Stückes d. The four holes k 2 located on the square are used to insert a mandrel for rotating the screw spindle k. This is mounted by means of a spherical head / in a corresponding bore in the support /. The cylindrical pin 77Z 1 serves as a bearing cover; the same is attached to the plate m , which is connected to the support / by means of the screw η and causes the support / to be guided uniformly. On the other hand, the latter leads, by means of the lower part of its round shaft / i, into a corresponding cavity in the piece d.

Anstatt der elliptischen Backe b kann man auch ein flaches Schneideisen ο verwenden, welches in dem Schlitz//, Fig. 5 und 7, des Supports f befestigt, und mittelst der Schraube q, welche mit ihrem kugeligen Kopf qt in eine entsprechende Aussparung des Schneideisens greift, der festen Backe α genähert und von dieser entfernt werden kann. Der Kopf r der' Schraube q ist zweimal durchbohrt, zum Einstecken eines Doms behufs Drehens derselben.Instead of the elliptical jaw b one can also use a flat die ο , which is fastened in the slot //, Fig. 5 and 7, of the support f , and by means of the screw q, which with its spherical head q t in a corresponding recess of the Cutting iron engages, the fixed jaw α can be approached and removed from this. The head r of the screw q is drilled twice for inserting a mandrel by turning it.

Bei der zweiten Modification, Fig. 6, wird immer ein Schneideisen ο statt der elliptischen Backe angewendet. Zum Abschneiden des Rohres dient das Messer A, Fig. 6, welches ähnlich wie das Schneideisen ο von der Schraube q bewegt wird, nur steht der Schlitz .? s in dem es sich führt, normal zum vorigen, so dafs im Querschnitt ein Kreuz erscheint, Fig. 5 und 7.In the second modification, Fig. 6, a die ο is always used instead of the elliptical jaw. The knife A, Fig. 6, is used to cut the pipe, which is moved by the screw q in a similar way to the die ο , only the slot stands. s in which it is normal to the previous one, so that a cross appears in cross-section, Figs. 5 and 7.

Die Schneidbacke b besitzt ebenfalls einen Schlitz u für dieses Messer, damit man nicht nöthig hat die Backe herauszunehmen, sondern gleich nach beendigtem Schneiden des Gewindes das Messer A zum Abschneiden anwenden kann. „The cutting jaw b also has a slot u for this knife, so that one does not have to take out the jaw, but can use the knife A for cutting immediately after the thread has been cut. "

Was die Schneidbacken anbetrifft, so mag darüber noch bemerkt werden, dafs für Rohre gröfseren Durchmessers immer diejenigen Stellen in Wirksamkeit treten, welche am weitesten von der Mitte der Backe entfernt sind, während für kleinere Rohre die Backe immer an ihrer mittleren Stelle wirkt.As for the cutting jaws, it should be noted that for pipes larger diameter always those places come into effect which are furthest from the center of the jaw are removed, while for smaller tubes the jaw is always on theirs middle point acts.

Die Schneidbacke ^1 der zweiten Kluppe kann für zwei Gewinde verschiedener Steigungen benutzt werden, da man dieselbe umdrehen kann.The cutting jaw ^ 1 of the second clip can be used for two threads of different pitches, because you can turn the same.
