| 24 | Retrieval tool | US15069968 | 2016-03-15 | US09598922B1 | 2017-03-21 | Douglas T. Beynon |
| A tool retrieves material from a well. The tool has a cylindrical tool body, malleable members, and a cylindrical jacket. The tool body defines a chamber adapted to receive material for retrieval. The malleable members are on the lower end of the tool body and preferably are made of a relatively hard, tough malleable material such as steel. They are bendable from an open position allowing material to enter the chamber to a closed position capturing the material. The jacket is mounted on the exterior of the tool body and has a mill surface which is adapted to bend the malleable members from the open position to the closed position. Relative axial movement of the jacket and the tool body causes the malleable members to bear on the mill surface and bend to the closed position. | ||||||

| The invention provides an apparatus and method for taking samples of soil and other materials in an efficient manner as well as for maintaining a high level of integrity of the samples. Using a wire line and a release and retrieve assembly, the sampling tube is lowered into an auger that has been bored into the ground to the desired depth. Once lowered to the bottom of the auger, the sampling tube is locked into place and the release and retrieve assembly is removed from the auger. A portion of the sampling tube extends beyond the drill bit. As the auger is drilled farther into the ground, the sampling tube is filled with soil or whatever material is present, without such soil or other material having been disturbed by the drill bit. This provides integrity of the sample. After the sample has been collected in the sampling tube, the release and retrieve assembly is reinserted into the auger and reattached to the sampling tube, which is then unlocked and retrieved out of the auger. | ||||||

| The present invention comprises a novel method and apparatus for sinking drill holes in underground rock formations while generating drill cores as rock samples. More particularly, the present invention discloses a method and apparatus which allows for an expanded analysis of ground formations over a larger area through the extraction of drill cores as rock samples. The method and apparatus herein disclosed allows one to drill a number of core shaft sections from the base of a main shaft section in various directions in order to obtain a number of sample cores. | ||||||
| 29 | 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. | ||||||
| 30 | Apparatus and method for taking soil samples | US396292 | 1982-07-08 | US4456079A | 1984-06-26 | Charles L. Rassieur |
| In a rotary table driven hollow auger type sampling device, a rod is mounted at an end above the rotary table to be substantially fixed against rotation, but for axial movement. The rod extends through a hollow spindle driven by the table, and is fixedly mounted below the table to the upper end of a thin wall sampling tube mounted within a hollow auger to project a short distance below the lower end of the auger. The rod, hence the sampling tube, is forced downwardly with the auger, but is positively restrained from rotation. | ||||||
| 31 | Earth boring auger | US62919 | 1979-08-02 | US4248313A | 1981-02-03 | Aaron Bonca |
| In a hollow stem auger for earth boring of the kind having spring loaded valve members at the bottom of the stem to permit the passage of test implements such as corers and vane test implements, the auger bit is constructed with a cage formation enclosing the valve member and supporting a bottom ring carrying cutting teeth. Interference of the valve members with a test implement is prevented by using an uncoupleable cylindrical sleeve surrounding the implement which sleeve can be lodged between the valve members to hold them open during use of the implement. | ||||||
| 32 | Test boring drill bit | US55223975 | 1975-02-24 | US3915245A | 1975-10-28 | TUCCILLO RALPH J |
| An apparatus for carrying out a test boring wherein the drilling and sampling operations are carried out in one operation is described. A drilling bit is detachably secured to a modified split-barrel sampler which serves as the bottom member of a drill rod. The shank of bit contains (1) a set screw located in a recessed area of the shank in contact with the sampler and releasable by a turn of the bit, (2) an overriding clutch set to engage the sampler on rotation and (3) an overriding clutch set to engage the sampler on vertical withdrawal, the three elements to operate sequentially. The split-barrel sampler is modified in two ways; (1) the ball of the ball check valve is not present during the drilling operation, but is dropped down the drill pipe at the end of the drilling operation and prior to the sampling operation so that it seats on the base of the check valve whereby the ball check valve becomes constituted and, (2) the vent ports which are normally present in a split-barrel sampler are plugged.

| 34 | 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.

| 35 | Retractable drill bits | US3603413D | 1969-10-03 | US3603413A | 1971-09-07 | GRILL WERNER K; LINK HOWARD D |
| Rotary drill bit cutters lowered on a carrier through a tubular drill string to a drive mandrel or body at the lower end of the string. A device orients or aligns the cutters with slots in the mandrel into which the cutters are expanded and then locked in expanded condition by the carrier, enabling drilling torque and weight to be transmitted from the rotating drill string and mandrel to the cutters, causing the latter to produce a cutting action in the formation. Elevation of the carrier retracts the cutters inwardly of the mandrel for withdrawal through the drill string to the drilling rig. The carrier may support a core tube for receiving a core produced by the cutters.
