gehoben, worauf er niederfällt und das Federspiel von neuem beginnt. Fig. 2 zeigt eine andere elastische Aufhängung des Bohrers an dem Zwischenstück. Die Wirkungsweise ist hier folgende :
Beim Anhub des Bohrzeuges geht zunächst nur das oberhalb des Zwischenstückes befind-
EMI2.2
zwischen die schrägstehenden Platten p, welche sich nun in wagerechter Richtung nach aussen bewegen und dabei die elastische Einlage l gegen die Rohrwandung n pressen. Erst wenn die elastische Einlage l genügend zusammengepresst ist, erfolgt allmählich der Anhub des unteren Gestänges e, ohne dass bei diesem Anhub ein Stoss erfolgt.
Wenn dann das gesamte Bohrzeug auf die notwendige Fallhöhe gebracht ist, fällt es nieder, wobei sich das obere Gestänge e nach dem Aufschlag des Meissels um die Strecke In in dem Zwischenstück h verschiebt. Hierauf geht das Gestänge e wieder nach oben und das Spiel beginnt von neuem. Bei Fig. 2 ist das Zwischenglied h starr mit dem Bohrer b verbunden.
PATENT-ANSPRÜCHE:
1. Spülrohrzwischenstück für Tief- und Schachtbohrung, dadurch gekennzeichnet, dass ein Teil des Spülrohres durch einen Schlauch ersetzt wird, der vor Inanspruchnahme durch Zug, Torsion oder unzulässige Biegung geschützt ist.

lifted, whereupon he falls down and the spring game begins again. Fig. 2 shows another elastic suspension of the drill on the intermediate piece. The mode of action here is as follows:
When the drilling tool is lifted, initially only the one located above the intermediate piece goes

between the inclined plates p, which now move horizontally outwards and press the elastic insert l against the pipe wall n. Only when the elastic insert l is sufficiently compressed does the lower rod e gradually lift without any impact occurring during this lift.
When the entire drilling tool is then brought to the required height of fall, it falls down, the upper rod e being displaced by the distance In in the intermediate piece h after the chisel has hit. The linkage then goes up again and the game starts all over again. In Fig. 2, the intermediate member h is rigidly connected to the drill b.
PATENT CLAIMS:
1. Flushing pipe intermediate piece for deep and shaft drilling, characterized in that part of the flushing pipe is replaced by a hose which is protected from being stressed by tension, torsion or impermissible bending.
