Description
Die Erfindung betrifft, eine weitere Ausbildung des nachgiebigen eisernen Grubenstempels nach dem Patent 305946 und| besteht in einer im Querschnitt kreisförmigen Holzeinlage in dem längsgeschlitzten, rohrartigen Oberteil. Hierdurch wird erreicht, daß die Holzeinlage mehrmals verwendet werden kann. Sie ist drehbar in den Stempeloberteil eingelagert, so daß nach Drehung um . ihre Längsachse frische Flächen den Schlitzen des Stempeloberteils zugewandt sind, die neue Angriffsflächen bieten.The invention relates to a further embodiment of the flexible iron pit punch according to patent 305946 and | consists of a circular cross-section Wooden insert in the longitudinally slotted, tubular upper part. This achieves that the wooden insert can be used several times. It can be rotated in the upper part of the stamp stored so that after turning around. their longitudinal axis fresh faces the slots of the The upper part of the stamp faces, which offer new surfaces to attack.
In der Zeichnung ist die Erfindung an einem Ausführungsbeispiel dargestellt.

Fig. 2 einen Längsschnitt des Grubenstempels. ' , 'Fig. 2 is a longitudinal section of the pit punch. ','
Fig. 3 ist ein Querschnitt nach der Linie . y A-B der Fig. 1.
Der Stempelunterteil besteht aus dem Rohr a und der Stempeloberteil aus dem Rohr b, das
in den Stempelunterteil kolbenartig eindringt. Als Klemmvorrichtung dient der Tragring d
mit den Stellschrauben e .und e1. In das
Rohr b ist die im Querschnitt kreisförmige Holzeinlage c eingelagert. Sie wird in zwei
gegenüberliegenden Seitenschlitzen von den Stellschrauben e und · e1 erfaßt. , Ist die Verkürzung
bis zum äußersten eingetreten, so läßt sich nach Auszug des Sternpeloberteils b
die Holzeinlage c um ihre Längsachse verdrehen, so daß die Stellschrauben im Holze
neue Angriffsfläche vorfinden.Figure 3 is a cross-section along the line. y AB of FIG. 1.
The lower part of the punch consists of the tube a and the upper part of the punch consists of the tube b, which penetrates the lower part of the punch like a piston. The support ring d with the adjusting screws e. And e 1 serves as a clamping device . The wood insert c, which is circular in cross section, is embedded in the tube b. It is gripped in two opposite side slots by the adjusting screws e and e 1 . If the shortening has occurred to the extreme, the wooden insert c can be rotated about its longitudinal axis after pulling out the upper part b of the star pelvis, so that the adjusting screws find new contact surfaces in the wood.
