Patent number: 8141663Abstract: A percussive assisted rotary drill includes a top sub for connection with a drill pipe. The drill pipe imparts torque to the drill and also supplies motive fluid to the drill. The drill includes a shank adapter to facilitate affixing a rotary drill bit to the drill. The motive fluid is divided between a bit flow which flows through the bit to clear debris at the bottom of the drill, and an actuator flow. An actuator, which may be in the form of a reciprocating piston, moves within the drill under the influence of the actuator flow to impart cyclical blows to the shank adapter. The blows are transferred to the drill bit through the shank adapter to provide a relatively high frequency low amplitude percussive force on the rotating drill bit to assist in the drilling operation. At least a portion of the actuator flow portion of the motive fluid is exhausted through the top end of the drill.Type: GrantFiled: July 15, 2011Date of Patent: March 27, 2012Assignee: Atlas Copco Secoroc LLCInventors: Leland H. Lyon, Warren T. Lay

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

Patent number: 6237704Abstract: A check valve system is for a fluid-actuated percussive drill assembly including a casing, a backhead connected with and extending into the casing, and a fluid distributor disposed within the casing. The backhead has a central axis, a supply passage extending along the axis, and an outer surface section extending circumferentially about the axis and disposed within the casing. The check valve system includes a port extending between the outer circumferential surface section of the backhead and the supply passage. Preferably, several ports are spaced circumferentially about the backhead outer surface. An annular check valve is disposed about the outer circumferential surface section of the backhead and is configured to alternately permit fluid flow through the backhead port and substantially seal the backhead port.Type: GrantFiled: September 29, 2000Date of Patent: May 29, 2001Assignee: Ingersoll-Rand CompanyInventor: Warren T.
