i. Patentirt im Deutschen Reiche vom II. October 1878 ab.i. Patented in the German Empire on October 2nd, 1878.

In der beiliegenden Zeichnung zeigt Fig. 1 einen Grundrifs und Fig. 2 einen Querschnitt eines Bleches, welches so geformt ist, dafs zwei Reihen Scheerentheile ausgestanzt werden können. Fig. ι veranschaulicht auch die Lage, in welcher die Scheerentheile ausgestanzt werden müssen, damit der Ansatz unter dem nöthigen Winkel entstehe.In the accompanying drawing, FIG. 1 shows a plan and FIG. 2 shows a cross section of a sheet which is so shaped that two rows of scissor parts can be punched out. Fig. Ι also illustrates the position in which the scissor parts must be punched out, so that the approach arises at the necessary angle.

Fig. 3 zeigt, in welcher Weise das Ausstanzen · geschehen mufs. Fig. 5 und 6 sind ein Paar Scheerentheile, wie sie aus der Stanze hervorgehen, die das in Fig. 1 dargestellte Blech bearbeitet. Fig. 7 und 8 veranschaulichen ein Paar Scheerentheile, nachdem die Ringe gelocht sind und nachdem die Löcher für die Schrauben oder Nieten ausgeschlagen oder gebohrt sind. Fig. 9 und 10 zeigen die Vereinigung von ein Paar Scheerentheilen zu einer fertigen Scheere.3 shows the manner in which the punching has to take place. Figs. 5 and 6 are a pair Scheerentheile, as they emerge from the punch that processes the sheet metal shown in FIG. Figures 7 and 8 illustrate a pair of scissor parts after the rings have been punched and after the holes for the screws or rivets are knocked out or drilled are. 9 and 10 show the union of a pair of scissor parts into one finished scissors.

Um diese Erfindung praktisch auszuführen, werden Bleche oder Streifen (wie in Fig. 1, 2, 3 und 4 gezeigt) in gewöhnlicher Weise gewalzt; die zu erhaltenden Profile richtet man nach Art und Gröfse der Scheeren ein, welche hergestellt werden sollen. Die gewalzten Bleche bringt man unter einen Durchstoß, worin ein Paar Stempel von der Form arbeiten,^ die die zu producirenden Scheerentheile haben sollen. Ein Stempel ist nach Fig. 5 profilirt, der andere nach Fig. 6. Das Blech wird am besten so in den Durchstofs eingelegt, dafs die mit den Vertiefungen versehene Seite auf dem Bett des Durchstofses aufruht, welches entsprechend geformt ist, der unebenen Fläche des Bleches ein festes Widerlager bietet und das Blech in der geeigneten Richtung genau führt.In order to carry out this invention in practice, sheets or strips (as in Figs. 1, 2, 3 and 4) rolled in the usual manner; the profiles to be obtained are set up according to the type and size of the scissors which are to be made. The rolled sheets one brings under a puncture in which work a pair of punches of the form that the should have parts of the scissors to be produced. One stamp is profiled according to Fig. 5, the other according to Fig. 6. The metal sheet is best placed in the perforation in such a way that the one with the indentations provided side rests on the bed of the penetration material, which is shaped accordingly is, the uneven surface of the sheet provides a firm abutment and the sheet in in the appropriate direction.

Die Stempel werden in den Durchstofs so eingesetzt, dafs die Scheerentheile schräge aus dem Blech oder Streifen ausgestanzt werden und somit der Ansatz unter dem geeigneten Winkel entsteht. Diese Operation ist einfach und von dem Arbeiter, welcher den Durchstofs bedient, leicht ausführbar.The punches are inserted into the penetration in such a way that the scissor parts are inclined the sheet metal or strip are punched out and thus the approach under the appropriate Angle arises. This operation is simple and carried out by the worker who passes through the material operated, easy to execute.
