US Patent:

20060006001, Jan 12, 2006

Filed:

Jul 9, 2004

Appl. No.:

10/887728

Inventors:

Cary Cooper - Winder GA, US

International Classification:

E21D 1/06

US Classification:

175053000, 175295000, 175415000

Abstract:

A percussive drill bit or reamer having a plurality of bit segments formed into a circular pattern suitable for drilling or reaming a hole. The bit segments are close-fitted and shaped to increase the cutting area and improve efficiency. Pressurized air exhausted from driving the percussion mechanism, or provided from a separate source, is passed into the bit segment and exits from a side face thereof into the gap formed between adjacent bit segments, thereby driving out any debris present in the gap and preventing binding of the bit segments. When utilized with mechanically-driven percussive bit assemblies, where air is only needed to remove debris from a rock face, separately-provided air is delivered to the bit segments of the present invention as described above to clear the gaps of debris.

Abstract:

The present disclosure describes various embodiments, as well as features and aspects thereof, of an improved drill bit assembly for a percussion boring system. More specifically, one non-limiting embodiment of an improved drill bit assembly for a percussion boring system comprises a bit and a product engagement member. The bit comprises a slant faced head and at least one exhaust port. The product engagement member comprises a product coupling portion and at least one fluid restriction portion. This improved drill bit assembly is such that, when the product engagement member is detachably engaged with the slant faced head of the bit, a first portion of the fluid stream expelled from the bit is directed substantially forward of the slant faced head and a second portion of the fluid stream is directed substantially rearward from the slant faced head.

Appl. No.:

14/207821

Inventors:

CARY COOPER - WINDER GA, US

International Classification:

E21B 7/04
E21B 10/26

US Classification:

175 73, 175406

Abstract:

Disclosed is a system and method employed in a horizontal directional drilling (“HDD”) process. An exemplary embodiment includes a drill bit with thirteen (13) or more splines for improved orientation of the drill bit relative to the orientation of a bent sub. Another exemplary embodiment includes a drill bit configured for receipt of a pulling device so that the drill bit may be used in a back reaming step to pull a product back through a pilot bore. Another exemplary embodiment includes a pulling device for mounting to a drill bit. The pulling device, in some embodiments, may include one or more pins for diverting and channeling air and/or fluid through the drill bit to lubricate a hammer assembly and/or the product being pulled as the drill string to which the drill bit is attached is retracted back through the pilot bore.

International Classification:

E21B 10/36

US Classification:

175414

Abstract:

The present disclosure describes various embodiments, as well as features and aspects thereof, of an improved drill bit assembly for a percussion boring system. More specifically, one non-limiting embodiment of an improved drill bit assembly for a percussion boring system comprises a bit and a chuck. The bit head comprises a slant face. The chuck comprises at least thirteen splines. This improved drill bit assembly is such that when the chuck is fully threaded onto the percussion boring system, and when the bit is detachably received by the chuck, the slant face of the bit is aligned to substantially within an average range of 0.00-27.70 arcseconds of an alignment reference point on the surface of the percussion boring system.
