KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Im Hauptpatent ist als Lösungs- oder Spülmittel für die Entfernung der Füllmasse eine Flüssigkeit, insbesondere Wasser, angegeben, das in den meisten Steinkohlengruben aus den Berieselungsleitungen zur Verfügung steht. In Gruben, die keine Wasserleitung besitzen, läßt sich die Füllmasse des hohen Stempelteils mit gleicher Wirkung wie bei der Ausspülung durch Druckluft oder andere gespannte Gase ausblasen. Dies ist insofern vorteilhaft, als man hierbei nicht von dem Vorhandensein einer Berieselungsanlage im Bergwerke abhängig ist, und weil die zum Ausblasen der Füllmasse in Frage kommenden Gase, wie Druckluft,The main patent is a solvent or rinsing agent for removing the filling compound Liquid, especially water, indicated that in most coal mines from the Irrigation lines are available. In pits that do not have a water pipe, leaves the filling compound of the high stamp part has the same effect as when rinsing Blow out with compressed air or other compressed gases. This is advantageous in that one does not depend on the presence of a sprinkler system in the mine and because the gases in question for blowing out the filling compound, such as compressed air,
Kohlensäure usw., sich bequem in Flaschen an jeden Punkt der Grube befördern lassen.Carbon dioxide, etc., can be conveniently transported in bottles to any point in the pit.
Die Fig. 1 und 2 zeigen geeignete Stempelarten für die Ausführung des Verfahrens nach der Erfindung, die sich aber auch für die Anwendung des Verfahrens zur Beseitigung der Füllmasse durch Wasserspülung eignen.1 and 2 show suitable types of stamps for carrying out the method according to of the invention, but also for the application of the method for eliminating the Suitable for filling compound by rinsing with water.
Fig. ι stellt beispielsweise einen mit Sand gefüllten Stempelunterteil α dar, in den durch den Stutzen w Druckluft eintritt. In dem hohlen Stempelteil α steht der obere Stempelteil h, der hier aus einem einfachen Holzstempel besteht. Beim Einleiten des Druckluftstrahls wird der Sand aus dem Unterstempel herausgeblasen und der Stempel gelöst.Fig. Ι shows, for example, a sand-filled lower punch part α , into which compressed air enters through the nozzle w. In the hollow stamp part α is the upper stamp part h, which here consists of a simple wooden stamp. When the compressed air jet is introduced, the sand is blown out of the lower punch and the punch is released.
Zum Ausblasen des Sandes dient der zwischen den Stempelteilen vorhandene Ringraum b. Paßt der obere Stempelteil schließend in den Stempelunterteil, so lassen sich Luftaustrittskanäle in einfacher Weise durch in das Holz gestemmte Längsschlitze s (Fig. 2) oder durch einen Beschlag mit gekreuztem Bandeisen c (Fig. 3) herstellen. The annular space b provided between the punch parts is used to blow out the sand. If the upper part of the punch fits into the lower part of the punch, air outlet ducts can be produced in a simple manner by means of longitudinal slots s (Fig. 2) cut into the wood or by a fitting with crossed iron c (Fig. 3).
Fig. 4 stellt einen Stempel dar, bei dem Ober- und Unterteil aus Eisen bestehen. Der Unterteil α ist ein Rohr, das durch eine angeschraubte oder angenietete Kappe mit Fußdorn unten geschlossen ist; der Oberteil h ist ein unten und oben geschlossenes, außen gerieftes Rohr, dessen Querschnitt Fig. 5 darstellt. Die Längsriefung des oberen Stempelteils erhöht dessen Widerstandsfähigkeit und schafft zwischen dem Ober- und Unterteil Kanäle b, durch die der Sand beim Einleiten der Druckluft entweichen kann.Fig. 4 shows a stamp in which the upper and lower parts are made of iron. The lower part α is a tube that is closed at the bottom by a screwed or riveted cap with a foot mandrel; the upper part h is an externally grooved tube closed at the bottom and top, the cross section of which is shown in FIG. The longitudinal grooving of the upper punch part increases its resistance and creates channels b between the upper and lower part through which the sand can escape when the compressed air is introduced.
