   Das Umsetzen, bezw. Drehen des Bohrers 13 erfolgt auf bekannte Art mittels steilen Schraubengewindes 28 und Ratsche 29. 



   Durch Einpressen von Wasser vor dem Vorschubkolben 4 in den äusseren Cylidner 1 wird vor Beginn der Bohrarbeit der Vorschubkolben 4 nach hinten gedrückt, worauf man die Wasserzuleitung absperrt ; durch Öffnen des Hahnes 2 wird nachher der Vorschubkolben dem Drucke der Pressluft ausgesetzt, wobei auch der Bohrer 13 in bekannter Weise in Thätigkeit tritt.

   Rock drilling machine.



   The subject of the present invention is a rock drilling machine in which the gradual advancement of the drill steel in accordance with the progress of the drilling work is automatically brought about by the compressed air used to operate the drill and regulated by a water buffer.



   In the accompanying drawing, a rock drilling machine according to the present invention is shown in longitudinal section.



   The drilling machine consists of the fixed part, the pressure cylinder 1, with an air inlet tap 2 and a suspension eye 3 in which the movable part, the feed piston 4, moves.



   The latter is sealed against the cylinder by means of two cuffs: on the one hand, the faceplate 5 seals the air flowing in through 2, and on the other hand faceplate 6 the buffer water located between the faceplate 6 and the front end of the cylinder 1.



   The feed piston 4 is hollow and simultaneously serves as a working cylinder for the piston 10, controlled in any known manner, with two piston bodies separated by a space, the piston rod 11 of which is coupled to the drill 13 by means of a sleeve 12.



   The piston 10 carries a cylindrical extension 14 which fits into the cover 15 of the preselub piston 4 and serves as a buffer when the piston moves back.



   The implementation, respectively. The drill 13 is rotated in a known manner by means of a steep screw thread 28 and a ratchet 29.



   By pressing water in front of the feed piston 4 into the outer cylinder 1, the feed piston 4 is pushed backwards before drilling begins, whereupon the water supply line is shut off; by opening the cock 2, the feed piston is subsequently exposed to the pressure of the compressed air, the drill 13 also coming into operation in a known manner.
 EMI1.1
 Water pass into the hollow piston rod and are expelled from there through the exhaust openings 20 and 27, so that the feed piston 4 moves up under the influence of the compressed air and the drill can advance further with the next move.



     Dor Hobrer then goes back in 4 to be advanced again, with the Yorschubkolboll 4 ahermats being advanced u. s. f. This way it becomes a bumpless. nllmlihligos and safe advancement of the drill in accordance with the progress of the drilling work is achieved automatically, as more water is pressed out of the cylinder 1. the further the piston 10 in the advancing piston moves forward during forward advancement.

PATENT-ANSPRUCH: Gesteinsbohrmaschine, dadurch gekennzeichent, dass der für den 4arbeitskolben als Cylidner dienende Vorschubkolben (4) an der Rückseite dem Drucke der zum Betriebe der Bohrmaschin dienenden Pressluft ausgesetzt ist und durch diese in einem EMI1.2 an der hohlen Arbeitskolbenstange (11) auf Öffnungen (31) an der Wand des Vorschub- kolbens (4) umsomehr Wasser aus dem äusseren Cylinder in die hohle Kolbenstange und von da nach aussen entweichen kann, je weiter der Arbeitskolben (10) im Vorschubkolben (4) beim Vorwärtschube vorgeschnellt wird, so dass der Druckkolben durch die pressluft selbstthätig und nach Massgabe des Vorswchritens der Bohrarbeit allmählich vorrückt. PATENT CLAIM: Rock drilling machine, characterized in that the feed piston (4) serving as a cylinder for the 4 working piston is exposed on the back to the pressure of the compressed air used to operate the drilling machine and through this in a EMI1.2 on the hollow working piston rod (11) on openings (31) on the wall of the feed piston (4), the more water can escape from the outer cylinder into the hollow piston rod and from there to the outside, the further the working piston (10) in the feed piston ( 4) it is accelerated during the forward thrust so that the pressure piston advances automatically by the compressed air and according to the precondition for the drilling work. **WARNUNG** Ende CLMS Feld Kannt Anfang DESC uberlappen**. ** WARNING ** End of CLMS field may overlap beginning of DESC **.
