US Patent:

20060054360, Mar 16, 2006

Filed:

Sep 13, 2004

Appl. No.:

10/939558

Inventors:

David Velcover - Zion IL, US

International Classification:

E21B 7/20

US Classification:

175171000

Abstract:

A steering head that comprises a forward pivot block and a rearward pivot block. The forward pivot block is attached to a leading edge of a casing. The rearward pivot block is attached to a trailing portion of the casing, the leading edge being separated from the trailing portion by a gap in the casing. Extending between the forward and rearward pivot blocks is a central drive shaft. The central drive shaft includes a threaded portion and is rotatable to move a drive nut away from or towards the rearward pivot block. The central drive shaft, to either side of the drive nut, is covered by a cylindrical sleeve. A second internal sleeve extends between the rearward pivot block and the drive nut to protect the threads of the drive shaft from earthen debris when the casing is being advanced or reversed to steer the forward-most casing portion during operation.
