Abstract

1,221,261. Boring earth and rock. DELMAG VERWALTUNGS G.m.b.H. [trading as DELMAG-MASCHINENFABRIK REINHOLD DORNFELD]. 21 March, 1969 (22 March, 1968], No. 15019/69. Heading E1F. [Also in Division F2] A telescopically extendable drill rod assembly 20 for soil drilling comprises a drill rod 1 which is suspended by a rope 21 and swivel 5, a drill bit 3, a damper member 9 for supporting telescopic tubes such as 11, 12 in a collapsed condition, and a further damper member 7 on the rod 1 and engageable with a member 14 on the tube 11 when the assembly is extended. A damper member 17 on the tube 11 engages a member 15 on the tube 12 in the extended condition. The damper member 17 may alternatively be attached to the member 15. The assembly is driven by a rotary table 19 engaging lugs 13 on the tube 12. In an alternative embodiment (Fig. 4, not shown) the tubes are of square cross section.
