PATENTAMT.PATENT OFFICE.
Die Erfindung bezieht sich auf eine Vorrichtung, unterschrämte Kohle mittels Wasserdruckes hereinzugewinnen. Im Gegensatz zu schon bekannten, diesem Zwecke dienenden Einrichtungen, wirkt das Wasser hierbei nicht direkt auf mehrere abgedichtete Kolben mit kreisrunder Druckfläche, sondern vom Innern eines Schlauches aus auf ein einziges Druckstück mit rechteckiger Druckfläche, welchesThe invention relates to a device to win in undermined coal by means of water pressure. In contrast to already known ones that serve this purpose Facilities, the water does not act directly on several sealed pistons circular pressure surface, but from the inside of a hose onto a single pressure piece with a rectangular printing area, which
ίο keine Abdichtungen und daher auch keine Erneuerungsarbeiten erfordert. Bei gleicher Länge der Einrichtung wird außerdem eine größere wirksame Druckfläche erzielt.ίο no seals and therefore none Requires renovation work. If the facility is the same length, a larger effective printing area achieved.
In Fig. ι der Zeichnung ist der Gegenstand im Querschnitt vor der Druckwirkung, in Fig. 2 in der Längenansicht und in Fig. 3 im Querschnitt nach der Druckwirkung dargestellt. In Fig. Ι of the drawing, the object is in cross section before the pressure effect, in Fig. 2 is shown in the longitudinal view and in Fig. 3 in cross section after the pressure effect.
Der Hauptkörper α hat eine prismatische Aussparung zur Aufnahme des Schlauches b und des Druckstückes c. Bei leerem, zusammengefaltetem Schlauche füllt dieser mit dem Druckstücke die Aussparung ganz aus (Fig. 1). Wird Schlauch b mittels einer · bei d anzuschließenden hydraulischen Pumpe mit Wasser gefüllt, so drängt er das Druckstück c aus der Aussparung (Fig. 3).The main body α has a prismatic recess for receiving the hose b and the pressure piece c. When the hose is empty and folded up, it completely fills the recess with the pressure piece (Fig. 1). If hose b is filled with water by means of a hydraulic pump to be connected at d , it pushes pressure piece c out of the recess (FIG. 3).
Die Vorrichtung eignet sich daher vorteilhaft zur Hereingewinnung unterschrämter Kohle.The device is therefore advantageously suitable for attracting undercut Money.
