Patent number: 7832504Abstract: A bit assembly is for a percussive drill that includes a casing with an interior chamber and includes a bit connectable with the casing and having a longitudinal bore and an axis through the bore. The bore has a retainer portion with one or more generally conical inner surfaces extending circumferentially about and facing generally toward the axis. A generally cylindrical valve has a longitudinal passage with an inlet fluidly connectable with the casing chamber and an outlet fluidly connectable with the bit central bore and an axis through the passage. An engagement portion with at least one generally conical outer surface extends circumferentially about and faces generally away from the valve axis. The valve engagement portion is disposable within the bit bore retainer portion such that the valve conical outer surface is disposed within and against the bit conical inner surface to retain the valve coupled with the bit.Type: GrantFiled: April 27, 2006Date of Patent: November 16, 2010Assignee: Atlas Copco Secoroc LLCInventors: Dale R. Wolfer, Timothy J. Plunkett, Leland H. Lyon

Publication number: 20100126778Abstract: A raise boring reamer assembly includes a saddle, and a journal assembly carried by the saddle. The journal assembly includes nose and gage shanks, and a cutter is carried by the journal assembly. Nose and gage wiper rings are positioned proximate to the nose and gage shanks, respectively. The nose and gage wiper rings move debris in opposed directions in response to the rotation of the cutter.Type: ApplicationFiled: January 27, 2010Publication date: May 27, 2010Applicant: ATLAS COPCO SECOROC LLCInventor: Andrew J. Osborne, JR.

Publication number: 20100102513Abstract: An earth bit includes a cutting cone rotatably mounted to a lug, and a seal assembly positioned to provide a seal between the cutting cone and lug. The seal assembly includes first and second rigid rings, and a first elastomeric sealing ring which carries the first rigid ring. The second rigid ring rotates in response to the rotation of the first elastomeric sealing ring, so that the second rigid ring is less likely to lock.Type: ApplicationFiled: October 23, 2008Publication date: April 29, 2010Applicant: ATLAS COPCO SECOROC LLCInventor: Gregory W. Peterson

Patent number: 7467675Abstract: A device is for channeling solids and fluids within a reverse circulating, fluid operated drill that has first and second ends, an axis extending between the ends, a casing and a piston. The casing has a bore extending between the drill ends and drive and valve chambers defined within the bore, the piston being movably disposed within the bore. The channeling device includes an elongated body disposeable within the casing bore so as to extend along the casing axis and through the piston. The body has a longitudinal axis, a first end locatable proximal to the drill first end, and a second end spaced from the first end and locatable proximal to the drill second end. A material transport passages extends axially between the two body ends and provides a path for moving solid materials through the drill. A fluid passage is configured to couple the valve and drive chambers.Type: GrantFiled: June 6, 2006Date of Patent: December 23, 2008Assignee: Atlas Copco Secoroc LLCInventor: Warren T. Lay
