Abstract
Abstract Well and exploratory drilling apparatus whose rotary motion is modified by a vibrator to provide lateral movement of its bit. There is also disclosed a universal movement which enables such action to occur in a steerable assembly, while providing a passage for a conduit to supply motive fluid to the vibrator, and isolating the drill rod from at least some of the vibrating forces.

Claims Analysis
Total Claims: 22
Claim 1
Independent Claim
128 words
In combination: a rotary drill bit having an axis of rotation, a body, cutting means carried by said body for cutting a hole when rotated and vibrated around said axis of rotation; a free-orbiting vibrator having a case rigidly connected to said bit, said case having an internal race with a central axis, said vibrator having a freely orbiting, bearingless rotor inside said case adapted to roll around said race and thereby orbit therein, on a plane of vibration thereby exerting an orbiting lateral force having at least a component directed normal to said axis of rotation, said vibrator having a fluid inlet and a fluid outlet; and conduit means for receiving compressible motive fluid under pressure, supplying it to the vibrator, and exhausting it from said vibrator.
Claim 2
Dependent Claim
128 words

A combination according to claim 1 in which said conduit means includes a passage extending laterally and discharging at the side of the bit.
Claim 8
Dependent Claim
26 words
A combination according to claim 1 in which said conduit means is coaxial with said axis of rotation, and discharging at the face of the bit.
Claim 9
Dependent Claim
37 words
A combination according to claim 1 in which the vibrator comprises a cylindrical rotor orbitally mounted in a race, said rotor and race having respective diameters and central axes, said central axes being parallel to one another.
Claim 10
Dependent Claim
18 words

Claim 12
Dependent Claim
18 words
A combination according to claim 9 in which said central axes are normal to said axis of rotation.
Claim 13
Dependent Claim
35 words
A combination according to claim 9 in which there are a plurality of said vibrators, the central axes of one vibrator being disposed at different angle relative to the axis of rotation than the other.
Claim 14
Dependent Claim
49 words
A combination according to claim 1 further including a universal joint assembly connected to the body of said drill bit and adapted to be connected to a rod for turning said assembly and bit, said universal joint assembly having three cross axes, disposed at 120° relative to one another.
Claim 15
Dependent Claim
36 words
A combination according to claim 13 in which a universal member comprising a ring and two opposed sets of keys and keyways is disposed at each said axis, and keyed to two adjacent, axially aligned members.
Claim 16
Dependent Claim
27 words
A combination according to claim 13 in which a central passage is formed through said universal joint assembly, and a hose is passed through said central passage.
Claim 17
Dependent Claim
27 words
A combination according to claim 14 in which a central passage is formed through said universal joint assembly, and a hose is passed through said central passage.
Claim 18
Dependent Claim
21 words
A combination according to claim 8 in which said rotor comprises a plurality of disc-like bodies keyed together for simultaneous rotation.
Claim 19
Dependent Claim
24 words
A combination according to claim 1 in which the drill bit body is provided with a plurality of sidewardly-facing and laterally-projecting diamond-surface reamer stripes.
Claim 20
Dependent Claim
17 words
A combination according to claim 18 in which said reamer strips are surfaced with diamonds or bortz.
Claim 21
Dependent Claim
24 words
A combination according to claim 18 in which a flushing conduit discharges fluid laterally from said body at an elevation beneath said reamer strip.
Claim 22
Dependent Claim
19 words
A combination according to claim 1 in which said conduit means exhausts said fluid adjacent to the cutting means.
