  • the interior of the bit also has another annular shoulder 22 therebelow, which is of lesser inside and outside dimensions than the shoulder 20, by virtue of there being an inwardly chamfered surface 24 at the bottom of the cylindrical socket 26 separating the two shoulders.
  • the lower shoulder 22 and the socket 26 form a seat for a core barreling tube 40 on the drive means, as shall be explained; whereas the upper shoulder 20 has an annular groove 30 recessed therein, from which a series of symmetrically angularly spaced ports 32 open through the body of the head 10 to the working face 12 of the bit, between the points 14 thereon.
  • the ports are also canted to the axis of the head, and are so angled into 'the shoulder that they open into the socket 26.
  • the compressed fluid is intermittently discharged to the ports 32 to flush the removed earth material back through the clearance 34 between the pipe 2 and the wall of the excavation.
  • the fluid reaches the ports through a series of passages 36 which are formed within the drive means and the distal end section 2 of the pipe, as shall be explained more fully hereinafter.
  • the drive means 4 also includes an annular anvil 38 which is slidably engageable in the upper, thinner walled portion of the distal end section 2, and sized to seat on the shoulder 3.

  • the keyway 50 for the bushing, and the length of the bushing are sized in relation to the pin, to allow for play between the tube and the anvil, axially thereof; and a coiled spring 52 is interposed about the bushing 46, between the head and the underside of the anvil, to bias the tube in the downward direction, toward the flange 48' of the pin.
  • a coiled spring 52 is interposed about the bushing 46, between the head and the underside of the anvil, to bias the tube in the downward direction, toward the flange 48' of the pin.
  • the forward end portion 40 of the tube 40 is also adapted to lift or separate the core 18 from the earth formation when the drive means 4 is retracted from the rod.
  • the tube 40 is formed in two threaded and flushedcoupled parts, the more forward 40' of which is chamfered at the end, so as to mate with the chamfered socket 26 of the bit, and form an essentially air tight joint therebetween.
  • the more forward portion 40 also has an upwardly and outwardly tapered surface 54 formed between the cylindrical mouth 56 and the threaded collar 58 of the same; and when the two parts of the tube are assembled, a tapered wedge-like annular core lifter 60 is inserted within the more forward portion, to perform the core lifting and separating function in conventional fashion.
  • the outer cylindrical surface 62 of the anvil is closely machined to form a fluid seal with the bore of the pipe. Above the surface, however, the anvil is swaged inwardly and provided with a filleted shoulder 64 thereabout, from which a nipple-like shank or embossment 66 is upstanding on the axis of the anvil, and equipped with a wide circumferential groove 68 thereabout.
  • the bore 70 of the anvil is counterbored from above and below, and the upper counterbore 72 of the same is adapted to interengage with the hammer mechanism, as shall be explained, whereas the lower counterbore 74 provides a socket for the swivel pin 48, which is secured in the socket by means of a dowel 76.
  • the hammer mechanism 5 is a modified version of a standard down-the-hole air hammer mechanism, comprising an outer tubular casing 78 having a pipe hammer 80 reciprocably engaged about a stationary control rod 82 therein.
  • the control rod 82 is ported and infrastructured to enable the compressedfluid to reciprocate the hammer in known manner, and alternately to exhaust through porting 84 in the distal end 86 of the control rod.
  • the fluid enters the control rod through a port or ports in a spear-headed, piston-like cap 88 which is threaded onto the upper end of the casing and adapted to slidably engage with the wall of the bore of the pipe 2, as illustrated.
  • the ports 90 are equipped with spring-loaded throttle valves 92 that operate to produce a pressure drop between the upper and lower sides of the drive means, so that the fluid can assist in seating the anvil on the shoulder 3 of the pipe.

  • the drive means is retracted from the rod by an overhead hoist, such as a standard wire-line retriever, the dogs 96 of which are engaged about the spearhead 94 of the cap.
  • the hammer 80 interfaces with the annulus 102 at the upper end of the anvil, and applies intermittent blows to the anvil, as the pipe 2 is rotated thereabout.
  • the bit is continually advanced in the axial direction by the percussive effect of the hammer, and at the same time, is continually rotated by the rod pipe, so that the points 14 of the bit are reindexed with respect to the face of the excavation,
  • the exhaust porting 84 in the control rod is placed in communication with the passages 36, so as to exhaust the fluid about the bit.
  • the distal end portion 86 of the control rod is slidably inserted in the bore 72 of the anvil; and in the bore, there is a series of symmetrically angularly spaced and outwardly slanted ports 104, which open to the underside of the anvil, opposite the chamber 106 which is formed between the head 44 of the tube and the anvil.
  • the fluid enters a series of symmetrically angularly spaced flutes 108 in the bore 42 of the pipe, which commence below the level of the shoulder 3, and terminate in the distal end of the pipe, to communicate with the groove 30 and the ports 32 in the bit.
  • the open sides of the flutes are closed by the main body of the tube, and the socket 26 is occupied by the forward portion 40' thereof, so that the fluid canescape only through the ports 32.
  • a portion of the fluid will discharge through the axial opening of the bit, so as to assist in flushing out any accumulated debris which would otherwise prevent the tube from seating in the socket of the bit.
  • the spring 52 will be compressed by the tube to the point where the bushing 46 of the swivel head engages the face of the anvil; and thereafter, when the hammer 80 is applied to the anvil, the force of the hammer will operate on the tube only. until the anvil re-engages the shoulder 3 of the rod.
  • the operator can be assured that the tube will be properly seated before the drilling operation is begun.
  • a passage 110 through the pin 48 assures that the tube 40 is also pressurized, so that the debris can move only in the direction outward through the clearance 34.
  • the tube can be changed at the same time to account for wear of the inner points of the bit; or the bit can be changed; or both can be changed.
  • the fluid may also be employed as a means of seating the drive means; as for example, where the drive means is run into the rod at a pressure below that at which the valves 92 open, and then the pressure is raised to open the valves and commence drilling.
