## Abstract

A tool for making up and breaking out a drill string at an exit side of a bore. The tool includes a fixed vice and a moveable vice for torqueing a pipe joint, a roller assembly for threading and unthreading adjacent sections of pipe, and a retainer assembly to retain a detached pipe section. The components of the tool are mounted on a frame, which is pivotally connected to a hydraulic machine such as an excavator. Thus, the tool may be manipulated to remove and add sections of pipe to a drill string remote from the primary horizontal directional drill.

## Claims

### Claim 1

A system for boring using a drill string, the drill string comprising a first end, a second end, and a middle portion wherein the middle portion is below a surface of the ground, the system comprising:
a horizontal directional drilling machine located at the first end of the drill string; and
a pipe handler disposed at the second end of the drill string comprising:
a vice assembly to apply a twisting force to the second end of the drill string;
a first retainer assembly; and
a second retainer assembly;
wherein each of the first retainer assembly and the second retainer assembly are located on a first side of the vice assembly to hold a pipe section.

### Claim 2 (depends on 1)

The apparatus of claim 1 further comprising a frame supporting the vice assembly and first and second retainer assemblies, wherein the frame is pivotable relative to the drill string.

### Claim 3 (depends on 2)

The apparatus of claim 2 further comprising a roller assembly supported by the frame to twist the second end of the drill string.

### Claim 4 (depends on 2)

The apparatus of claim 2 wherein the frame is pivotally attached to a hydraulic machine.

### Claim 5 (depends on 4)

The apparatus of claim 4 wherein the hydraulic machine provides at least part of the operative force for the pipe handler.

### Claim 6 (depends on 1)

The apparatus of claim 1 wherein the vice assembly comprises:
a first vice; and
a second vice:
wherein the first vice is fixed and the second vice is moveable relative to the first vice.

### Claim 7 (depends on 6)

The apparatus of claim 6 wherein the second vice is disposed between the first vice and the first retainer assembly.

### Claim 8 (depends on 7)

The apparatus of claim 7 further comprising a roller assembly supported by the frame between the first and second retainer assemblies to rotate a pipe section located at a second end of the drill string.

### Claim 9

A tool for making up and breaking out a pipe joint on the exit side of a bore and attachable to a hydraulic machine, said tool comprising:
a frame comprising a first end and a second end and pivotable relative to the hydraulic machine;
a first vice assembly and a second vice assembly mounted proximate the first end of the frame each adapted to grip a pipe section on opposing sides of a pipe joint distal from an entry side of the bore:
wherein the second vice assembly is moveable with respect to the first vice assembly; and
a retainer assembly supported on the frame between the first vice assembly the second end of the frame and adapted to hold a pipe section.

### Claim 10 (depends on 9)

The apparatus of claim 9 wherein the frame is pivotable about a vertical axis and a horizontal axis.

### Claim 11 (depends on 10)

The apparatus of claim 10 further wherein the hydraulic machine provides power to the tool.

### Claim 12 (depends on 9)

The apparatus of claim 9 further comprising a plurality of rollers supported by the frame to provide a twisting force to a pipe section.

### Claim 13 (depends on 1)

The apparatus of claim 1 wherein the retainer assembly further comprises a first retainer and a second retainer, and wherein the plurality of rollers are located between the first retainer and the second retainer.

### Claim 14 (depends on 12)

The apparatus of claim 12 wherein at least some of the plurality of rollers are pivotally connected to the frame.

### Claim 15

A method of drilling a hole having an entry side and an exit side comprising:
boring a hole with a horizontal directional drilling machine;
advancing a drill string comprised of a plurality of pipe sections from the entry side of the hole to the exit side of the hole;
placing a tool comprising a vice assembly, a roller assembly, and a retainer assembly proximate the exit side of the hole;
adjusting the tool such that a pair of adjacent pipe sections of the drill string are within the vice assembly of the tool:
separating the pair of adjacent pipe sections with the vice assembly;
unthreading one of the pair of adjacent pipe sections from the drill string through operation of the roller assembly; and
retaining the unthreaded pipe section in the retainer assembly.

### Claim 16 (depends on 15)

The method of claim 15 wherein the tool is pivotally mounted on a hydraulic machine.

### Claim 17 (depends on 16)

The method of claim 16 further comprising the step of pivoting the tool such that it is substantially parallel to the drill string.

### Claim 18 (depends on 16)

The method of claim 16 further comprising operatively connecting the tool to the hydraulic machine such that the machine provides at least a part of the operating force for the tool.

### Claim 19 (depends on 15)

The method of claim 15 wherein the retainer assembly comprises a first retainer and a second retainer.

### Claim 20 (depends on 15)

The method of claim 15 further comprising placing the unthreaded pipe in a pipe storage location.

### Claim 21 (depends on 15)

The method of claim 15 further comprising:
placing a pipe section in the retainer assembly;
threading the pipe section to the drill string with the roller assembly; and
providing torque to the pipe section and drill string with the vice assembly to secure a connection between the pipe section and drill string.

### Claim 22 (depends on 21)

The method of claim 21 further comprising providing a backreamer to a terminal end of the pipe section.
