Description

Grubenstempel. Die Erfindung betrifft einen Grubenstempel, welcher mit einer teilweise mit Bergeversatz gefüllten Haube versehen ist.Pit stamp. The invention relates to a pit punch, which is provided with a hood partially filled with a mountain offset.

Das Neue besteht darin, daß die Haube, welche über dem Stempel liegt, oben durch eine halbkugelförmige Schale abgeschlossen ist, auf welcher zwei durch Bolzen zusammengehaltene und gegeneinander verstellbare Spannhölzer mit Schrägflächen lagern.The new thing is that the hood, which lies over the stamp, at the top is closed by a hemispherical shell, on which two by Bolts held together and adjustable against each other with sloping surfaces to store.

In der Zeichnung ist die Erfindung in einer Ausführung beispielsweise dargestellt, und zwar zeigen: Abb. z glas durch Stempel abgestützte Hangende, Abb. a einen Stempelkopf im Schnitt, Abb. 3 eine Seitenansicht, Abb. q. eine Draufsicht auf den Stempelkopf.In the drawing, the invention is in one embodiment, for example shown, namely: Fig.z glass hanging wall supported by stamps, Fig. a shows a punch head in section, Fig. 3 is a side view, Fig. q. a top view on the stamp head.

Das Hangende a wird in bekannter Weise durch längsverlegte Riegel b, querliegende Riegel c und die Stempel d abgestützt. Die Stempel J sind mit eisernen Hauben e versehen, inwelchenLöcher f angeordnet sind,durch die bei großer Belastung der in das Innere der Hauben e eingefüllte Bergeversatz g (Sand, Bergemenge, Kohlenklein usw.) entweicht.The hanging wall a is in a known manner by means of longitudinally laid bars b, transverse Latch c and the punch d supported. The stamp J are provided with iron hoods e, in which holes f are arranged through which in the case of heavy loads, the rock backfill g (sand, Mountains, coal, etc.) escapes.

Der Kopf der Haube ist halbkugelförmig ausgebildet, und zwischen ihm und den Längsriegeln b sind Spannhölze h verlegt, welche zweckmäßig mit den die Halbkugel aufnehmenden Ausschnitten i versehen werden. Spannschrauben k halten die Hölzer h zusammen. Um den Querriegeln c eine gute Auflage zu geben, werden die Spannhölzer h an die oberen inneren Auflagekanten i abgeschrägt. Beim Rauben der Stempel löst man die Spannschraube k, wodurch die Stempel entlastet und frei werden und mittels Seil und Haken gefahrlos zu rauben sind.The head of the hood is hemispherical, and between it and the longitudinal bars b, tensioning timbers h are laid, which are expediently connected to the Hemispherical receiving cutouts i are provided. Clamping screws k hold the Woods h together. In order to give the crossbars a good support, the tensioning timbers h beveled on the upper inner support edges i. When robbed the stamp loosens one the clamping screw k, whereby the stamp is relieved and free and by means of The rope and hook can be stolen safely.

Statt der Spannhölzer za können auch Spanneisen verwendet werden.Clamping irons can also be used instead of the tensioning timbers.
