摘要： A reciprocating rotary drill bit is disclosed to include a coupling member for coupling the drill bit to a source of drill bit drive power and a cutter member for drilling into a workpiece. The coupling member and the cutter member are slidably associated and include overlapping protruding portions which delimit the upward and downward travel of the cutter member with respect to the coupling member. The slidable association permits reciprocation of the cutter member with respect to the coupling member as the drill bit is rotated into the workpiece. The coupling member also includes protrusions which extend into grooves defined in the cutter member to rotationally secure the two members whereby the cutter member rotates when the coupling member rotates.

摘要： An improved rotary drill bit comprised of two or more elongated generally cylindrical drill members the lower ends of which form a cutting face. Each of the drill members includes a plurality of vertically spaced rows of diamond-shaped openings disposed, or formed, in the sides, or wall, thereof, the openings in adjacent rows being offset from each other and overlapping at their upper and lower ends whereby as the lower ends of the drill member wear away, cutting edges are continuously formed thereon by the diamond-shaped openings.

摘要： An earth boring machine with a rotating cutter head having a multiple of individual cutters positioned at different distances from the center of rotation and angularly spaced from one another on the cutter head while the cutter head itself is shaped to direct the cuttings into a collecting area, which may be under the center of the rotary head or which may be concentric about the center area, has elevator means, which may be mechanical, hydraulic or pneumatic, to remove the cuttings from the collection area, and has one or more crushing rollers thereon arranged to crush cuttings which are too large for effective removal by the elevator means into small chips or fragments together with barrier means for restraining such oversize pieces in the path of the crushing roll or rollers so as to prevent their entry into the collection area until they have been adequately crushed. The barrier means so provided are arranged to permit the smaller fragments and chips to move into the collection area with little impedance.

摘要： A method for forming a drill bit for drilling through either consolidated or unconsolidated sedimentary sections comprises (1) forming a recess in the bottom cutting surface of the drill bit, and (2) shaping the recessed cutting surface into a continuous non-cylindrical surface of revolution having a height to radius ratio of substantially three to one. Two other methods are disclosed. A preferred drill bit made by the method has a conical recess, and another has a paraboloidal recess, each recess having a vertex and a plurality of exit transverse passages. The exit passages have spaced apart inlet openings around their vertex, one modification having the openings spaced from each other around its vertex and another having the openings tangent to each other around its vertex for forming a very efficient and high penetration rate drill bit.

摘要： An apparatus and method for excavating tunnels with electrically generated shock waves. The tunneling apparatus is comprised of a rotatable barrel for cutting a peripheral ring about a core and a bit which simultaneously bores a hole in the center of the core. The drive for the rock bit also contains electrodes which are pulsed to produce shock waves in the core to peel off a desired thickness of rock layer.

摘要： Drilling apparatus having a dual pipe string connected to a drill bit by a bit sub, with the bit sub comprising one or more subs, with the outer surface of each sub including turbulence producing means formed thereon. Compressible fluid is flow connected to the pipe annulus while drilling fluid is flow connected to the hole annulus, and the length of the bit sub is adjusted to control the pressure drop of the noncompressible fluid thereacross to thereby control the ratio of compressible and noncompressible fluid which flows up through the central passageway, carrying formation samples formed by the bit admixed therewith.

摘要： A method of drilling bore holes which enables a cylindrical solid core sample to be obtained from a formation. A coring bit together with a core barrel and concentrically arranged drill pipe provides central and annular passageways. The annular passageway is used for circulating fluid to the bit and back up the bore hole annulus while the central passageway provides for the return of drilling fluid and cores. The circulating fluid is forced down through the drill string annulus to the drill bit, and back up through the hole annulus to thereby remove debris and cool the bit in an improved manner. The cores which have been cut by the bit are accumulated within the core barrel and from time to time the pressure of the drilling fluid is increased while the central passageway is opened to the flow of fluid, thereby forcing the fluid to flow into and up through the central passageway, carrying the accumulated cores therewith. A predetermined pressure drop is maintained across the face of the diamond bit by adjusting the bearing pressure thereof with respect to the formation to thereby enable the bit to cooperate with the formation in a manner analogous to the action of a valve.

摘要： A well-boring apparatus is disclosed as including a core bit to cut material within a borehole in the form of a core during a well-drilling operation and a core crusher to crush the core material between the wall of the borehole and the core crusher. The core bit and core crusher also include passages for delivering fluid to the bottom of the borehole to serve as a cutting fluid for the core bit and to flush the core material from the cutting surfaces of the core bit.
