| 121 | Core drilling tool for boreholes in rock | US038609 | 1987-04-15 | US4773489A | 1988-09-27 | Friedhelm Makohl |
| A core drilling tool for bore-holes includes a stem for connection to the string and an outer rotating tube for rotating a drill bit mounted thereon. A core tube is mounted in a central passage by a latch means to remove the core tube and/or replace it. The outer tube is rotated by a downhole motor such as a Moineau type motor. The diameter of the central passage through the stator is equal to the maximum diameter of the core tube plus the eccentricity of the stator to permit passage of the core tube into and out of the tool. Thus coring can be achieved without tripping the tool. Various details of the structure are described. | ||||||
| 122 | Fixing mechanism for a wireline core barrel of core drilling equipment | US741556 | 1985-06-05 | US4664204A | 1987-05-12 | Nikolay D. Nenkov; Ivan B. Petrov; Stoyko P. Peev |
| Wireline core barrel fixing mechanism incorporating a fixer which prevents any wireline core barrel deformations, fixes the wireline core barrel to the hollow drill bit, and signals any drilling process interruptions. The wireline core barrel fixer comprises a cylindrical hollow body adapted to be mounted within the drill bit and incorporating selectively operated rollers for locking the hollow body to the drill, the rollers being mounted in planes parallel to each other and perpendicular to the geometrical axis of the cylindrical hollow body. The upper end of the fixer is connected to a cap, in the lower part of which opposite longitudinal slots are cut. The fixer is mounted inside a cylindrical hollow body, the upper end of which is connected to the stopper bar and in its lower part a locking bar and a set nut are mounted, connected to the fixer. The lower end of the cylindrical hollow body is threaded, and on the thread a longitudinally extending extensible and compressible spring body is fastened, the lower end of the spring body gripping a signal stem. On the end of signal stem there is mounted a sealing ring, and under it there is mounted a bearing assembly carrying a core-receiving and gripping barrel. The entire assembly of cap, hollow body, slit spring body, and core barrrel carrying a drill core is selectively pulled up out of the hollow drill pipe string by means of a wire or rope attached to the cap. | ||||||
| 123 | Shrouded core catcher | US646576 | 1984-08-31 | US4605075A | 1986-08-12 | Steven R. Radford; J. Stanley Davis |
| A fragmented or unconsolidated core can be cut and retained within a coring tool without substantial disturbance of the core by the use of a shrouded core catcher. A core catcher is concentrically disposed within the coring tool and outside of a smooth, cylindrical sleeve telescopically disposed inside of the core catcher. The core catcher in turn is coupled to a lower assembly which can be selectively longitudinally fixed within the coring tool, but which is otherwise temporarily coupled to the sleeve. As the sleeve is longitudinally pulled upward after the completion of the coring operation, the lower assembly becomes longitudinally fixed within the coring tool and the sleeve, which heretofore has fully covered and concealed the core catcher, begins to be withdrawn from the core catcher, leaving it unconcealed. Ultimately, the core catcher is at least partially uncovered, thereby permitting activation and contact between the core catcher and the core disposed within the coring tool. However, at all times during the coring operation, the core catcher remains concealed behind the cylindrical sleeve which extends in the coring tool throughout the substantial length of the core. | ||||||
| 124 | Device in core barrels | US308527 | 1981-10-05 | US4452321A | 1984-06-05 | Sune W. Eriksson |
| A device in core drilling for indicating when a core barrel placed in a rotatable hollow drill rod is no longer capable of receiving a further quantity of reamed-out core material includes a valve which at said condition of the barrel constricts the passage for flushing medium flowing between the core barrel and the bore of the drill rod so that a readable flushing medium pressure increase occurs. The valve closes off said passage incompletely to allow a minor quantity of flushing medium to be taken to the drill bit mounted at the bottom of the drill rod, thereby to prevent said drill bit from being burnt out. | ||||||
| 125 | Earth drilling device for extracting earth samples | US165667 | 1980-07-03 | US4336849A | 1982-06-29 | Max Hug |
| An earth drilling device for extracting earth samples including a rotatable drill tube and means for rotating said drill tube, a drill bit supported by said rotatable drill tube, said drill bit and said drill tube defining an inner shoulder, a hollow probe movably disposed within said drill tube and adapted to be supported by said inner shoulder, an exchangeable plastic sleeve disposed within said hollow probe, and means for extracting said hollow probe and associated plastic sleeve containing an earth sample without removing the drill tube from the earth. | ||||||
| 126 | Down-the-hole motor for rotary drill rod and process for drilling using the same | US575429 | 1975-05-07 | US3990524A | 1976-11-09 | Gerald T. Sweeney |
| The motor is adapted to be used to drive a rotary drill rod of the type comprising an elongated pipe having a longitudinally extending bore therethrough, a percussive bit at the distal end thereof, and an abutment thereon relatively transverse the bore adjacent the bit. The motor comprises a cylindrically outlined piston member which is adapted to be slidably engaged in the bore of the pipe and has a fluid operated hammer mechanism thereon for applying hammer blows to the rod through the abutment. It also comprises an anvil member which is coaxially interconnected with the piston member at a position relatively forwardly of the hammer mechanism and has a diameter no greater than that of the piston member so that it can be inserted in the bore ahead of the piston member and engaged with the abutment to receive and transmit the hammer blows into the abutment. In addition, the motor comprises fluid transmission means for operating the hammer mechanism, means on the relatively rear end portion of the piston member for admitting fluid to the same from the bore of the pipe when the motor is engaged in the bore, and means for discharging the fluid from the motor including means for passing fluid through the anvil member from the piston member. The motor also includes means on the piston member for causing a pressure drop in the fluid as it discharges from the motor, whereby a pressure differential can be generated across the motor axially of the members when the motor is engaged with the abutment and transmitting hammer blows thereto. | ||||||
| 127 | Apparatus for providing a packaged core | US566866 | 1975-04-10 | US3986555A | 1976-10-19 | William Robertson |
| A packaged core is obtained using a conventional core barrel system. A lining is provided in the core sample container of the core barrel. The core barrel is connected to a drill string extending into a borehole. As the drill string is rotated, the core sample moves into the sample container and inside of the lining. When the core barrel arrives at the surface, the sample core may be removed from the core barrel packaged in the lining. The core may be examined on site or the ends of the lining closed and the core completely packaged for shipment to the laboratory. | ||||||
| 128 | Drill tool comprising a core barrel and a removable central portion | US459990 | 1974-04-11 | US3951219A | 1976-04-20 | Abel C. Cortes |
| Apparatus for interchanging the central portion of a drill tool with a core barrel is disclosed. The interchange is effectuated without the need for raising the drilling tool with the drive turbine. Both the core barrel and the central portion of drilling tube have barrel tubes associated therewith and a seating associated with a receiver tube rotating with the tool holds the barrel tube in a vertical position. The end of the core barrel is spaced from the inside end of the barrel of the drilling tool to avoid friction and facilitate the cutting of the core. | ||||||
| 129 | Rotary drill rod | US47559874 | 1974-06-03 | US3893524A | 1975-07-08 | SWEENEY GERALD T |
| The drill rod comprises an elongated pipe having a longitudinally extending bore therethrough and an annular bit at the distal end thereof. The proximal end portion of the bore is adapted to slidably receive a piston-like means therein, but there is an annular shoulder about the periphery of the bore at the terminus of said portion to engage the means in the rod adjacent the bit. There are also means defining an annular seat about the periphery of the bore between the shoulder and the mouth of the bit, which is of lesser inside diameter than that of the shoulder, to engage an elongated member which is slidably inserted into the distal end portion of the bore through the opening in the shoulder when the piston-like means is engaged with the shoulder. The distal end portion of the bore has substantially the same diameter as the opening in the shoulder, but there is fluting in the peripheral wall of the bore, which extends generally longitudinally thereof between a point adjacent the shoulder and a point about the periphery of the seat, and porting in the body of the bit, which extends generally axially thereof between the fluting and the working face of the bit at the distal end thereof. Together, the fluting and porting form a passage about the member through which fluid can be released into the working face of the bit from a point adjacent the opposite end of the member. Additionally, the bit has a greater diameter than the pipe and is adapted so the released fluid can discharge from the face of the bit toward the proximal end of the pipe on the opposite side of the pipe from the member.

| 130 | Drilling apparatus with down hole motor | US28320872 | 1972-08-23 | US3854539A | 1974-12-17 | SWEENEY G |
| The apparatus comprises a rotary drill rod comprising an elongated pipe having a longitudinally extending bore therethrough and a percussive bit at the distal end thereof. Means define an abutment which is relatively transverse the bore adjacent the bit and operatively connected with the bit to receive and transmit hammer blows into the working face of the bit. The apparatus also comprises drive means that include a piston-like member which is retractably inserted in the bore in slidable engagement with the wall thereof and has a fluid operated hammer mechanism thereon, the hammer of which is reciprocable between the member and the abutment to apply the blows to the abutment. In addition, there are fluid transmission means for operating the hammer mechanism including means for passing fluid through the piston-like member and means for exhausting the fluid into the region adjacent the working face of the bit after the mechanism has operated. There are also means on the rod whereby the exhaust fluid can discharge from said region toward the proximal end of the pipe on the opposite side of the pipe from the piston-like member; and means on the piston-like member for generating a pressure differential across the drive means longitudinally of the bore to maintain the mechanism in operative relationship to the abutment during the application of the blows.

| 131 | Device for taking soil-samples of a corer | US33510673 | 1973-02-23 | US3830320A | 1974-08-20 | VAN DER WIJDEN F |
| A device for taking samples of soil by means of a corer, comprising a pipe adapted to be driven in the soil, the corer being releasably locked in the pipe. The lower part of the pipe is provided with closing members adapted to be actuated from the surface, and in the open position, the closing members leave the lower part of the pipe free for passing the corer therethrough whereas in the closed position the closing members completely close the pipe. The corer is constructed as a stationary piston with a sleeve encompassing the piston and capable of being driven along the piston to a position in which the sleeve extends beyond the lower end of the pipe. In one embodiment, the closing members are formed as two plates with half circular positions pivoted to the pipe at diametrically opposed points near a corner between the straight diametral edge and the curved peripheral edge of the plates, such that in the closed position the plates abut with their straight edges and thus together form an abutment for the closed position.

| 132 | Cable-type coring apparatus for retrieving underground specimens | US3667558D | 1970-04-09 | US3667558A | 1972-06-06 | LAMBOT HONORE JOSEPH |
| A cable-type coring apparatus comprises a string of tubing with an annular coring bit at its lower end, a coring head with a core extractor slidable within the tubing, and means for retrieving the head with a cut core therein. Water under pressure forces the coring head and retrieval means downwardly until the head locks in coring position in the tubing with a latch action. An upward pull on the cable unlatches the head and also vents the water under pressure so that it no longer forces the assembly downward, whereupon continued pulling on the cable retrieves the coring head and cut core.
