Umfange berührend genau zusammenpassen.
Wird nun in bekannter Weise der Stempel angesetzt, wobei der Stift n die Höhenstellung des gegabelten Stempelkopfes bestimmt, und dann die Pfändungsschiene o mit Hilfe des Keiles p unter das Hangende getrieben, so nehmen die Stempelteile etwa die in Fig. 1 dargestellten Lagen zueinander ein. Der Gebirgsdruck wird jetzt dank der zentrischen Führung der Schraubenspindel b im Rohr e zentrisch auf die Feder h übertragen, deren Windungen sich dem Gebirgsdrucke gemäss ineinanderschieben. Ist nach und nach die Grenze der Zusammendrückbarkeit der Feder erreicht und soll der Stempel auch noch weiterhin an dieser Stelle Dienste tun, so wird die Mutter d durch Fäustel- oder Hammerschläge soweit zurückgezogen, wie es die Rückkehr zur Ausgangsstellung verlangt. Der Stempel kommt dabei also nicht zur völligen Entlastung.

Exactly touching each other.
If the stamp is now applied in a known manner, the pin n determining the height position of the forked stamp head, and then the seizure bar o driven under the hanging wall with the help of the wedge p, the stamp parts take approximately the positions shown in FIG. Thanks to the centric guidance of the screw spindle b in the pipe e, the rock pressure is now transmitted centrally to the spring h, the turns of which slide into one another according to the rock pressure. If the compressibility limit of the spring is gradually reached and the stamp is to continue to serve at this point, the nut d is pulled back by hammering or hammering as far as the return to the starting position requires. The stamp is not completely relieved.
