EMI1.1
Der Zweck der vorliegenden Neuerung ist, eine sichere Verbindung und ein schnelles Losmachen der Bohrstangen zu bewirken, um dadurch die Bohrarbeiten zu beschleunigen.
Fig. 1 stellt zwei bereits verbundene Bohrstangen,
Fig. 2 zwei zu verbindende oder aber loszumachende Bohrstangen,
Fig. 3 eine Draufsicht und
Fig. 4 den Querschnitt nach A-B dar.
Beide Bohrstangen a und b sind mit ineinander greifenden Vorsprüngen bezw. Ein : kerbungen versehen, und zwar greifen die Vorsprünge c, d der Stange b in entsprechende Einkerbungen g, f der Stange a und die Vorsprünge/ ;, t derselben Stange in entsprechende Einkerbungen der Stange b ein.
Auf die derart gebildete Verbindung wird eine an der Stange b befindliche Muffe 111 aufgesetzt (Fig. 2), wobei eine an dieser Stange befestigte Flachfeder 11 nachgibt.
Kommt die Muffe bis an den Bund p herab (Fig. 1), so springt die Feder II aus
EMI1.2
ssohrarbcit.
Sind die Stangen loszumachen (Herausziehen des Bohrzeuges), so drückt man mit dem Finger n und schiebt die Muffe in herauf, wonach die Stangen voneinander getrennt werden.
**WARNUNG** Ende DESC Feld kannt Anfang CLMS uberlappen**.

EMI1.1
The purpose of the present innovation is to effect a secure connection and a quick detachment of the drill rods in order to accelerate the drilling work.
Fig. 1 shows two drill rods already connected,
2 shows two drill rods to be connected or to be detached,
Fig. 3 is a plan view and
Fig. 4 shows the cross section according to A-B.
Both boring bars a and b are respectively with interlocking projections. A: provided notches, namely, the projections c, d of the rod b engage in corresponding notches g, f of the rod a and the projections /;, t of the same rod into corresponding notches of the rod b.
A sleeve 111 located on the rod b is placed on the connection formed in this way (FIG. 2), a flat spring 11 attached to this rod yielding.
If the sleeve comes down to the collar p (Fig. 1), the spring II springs out
EMI1.2
ssohrarbcit.
If the rods are to be loosened (pulling out the drilling tool), one presses with the finger n and pushes the sleeve up, after which the rods are separated from one another.
