UNDERGROUND BORING MACHINE
First Claim
1. An underground boring machine for creating a tunnel in a wall, the machine comprising:
- a vehicle frame;
a boom including a first end coupled to the vehicle frame and a second end;
a boring cutter head including a rotary joint, a first arm, and a second arm angularly spaced apart from the first arm, the rotary joint defining an axis of rotation and supporting the boring cutter head for rotation with respect to the second end of the boom, the first arm including a first end coupled to the rotary joint, a second end, and at least one disc cutter coupled to the first arm and oriented to engage the wall, the first arm extending from the first end toward the second end in a plane that is perpendicular to the axis of rotation, the second arm including a first end coupled to the rotary joint, a second end, and at least one disc cutter coupled to the second arm and oriented to engage the wall, the second arm extending from the first end toward the second end in a plane that is perpendicular to the axis of rotation.

Abstract
An underground boring machine includes a vehicle frame, a boom, and a boring cutter head. The boom includes a first end coupled to the vehicle frame and a second end. The boring cutter head includes a rotary joint, a first arm, and a second arm angularly spaced apart from the first arm. The rotary joint defines an axis of rotation and supports the boring cutter head for rotation with respect to the second end of the boom. The first arm includes a first end coupled to the rotary joint, a second end, and at least one disc cutter coupled to the first arm and oriented to engage the wall. The first arm extends from the first end toward the second end in a plane that is perpendicular to the axis of rotation. The second arm includes a first end coupled to the rotary joint, a second end, and at least one disc cutter coupled to the second arm and oriented to engage the wall. The second arm extends from the first end toward the second end in a plane that is perpendicular to the axis of rotation.

15. An underground boring machine for creating a tunnel in a wall, the undergound boring machine being supported on a floor defining a floor plane, the underground boring machine comprising:
-
a vehicle frame for supporting the underground boring machine on the floor, the vehicle frame defining a frame axis that is parallel to the floor plane; a boom including a first end slidably coupled to the vehicle frame, a second end, a first portion proximate the first end, a second portion pivotably coupled to the first portion, and a third portion proximate the second end and pivotably coupled to the second portion; a boring cutter head including a rotary joint, a first arm, and a second arm angularly spaced apart from the first arm, the rotary joint defining a rotary axis and being rotatably coupled to the second end of the boom, the first arm including a first end coupled to the rotary joint, a second end, and at least one disc cutter coupled to the first arm and oriented to engage the wall, the second arm including a first end coupled to the rotary joint, a second end, and at least one disc cutter coupled to the second arm and oriented to engage the wall, wherein the second boom portion pivots with respect to the first boom portion about a first axis that is substantially perpendicular to the frame axis, wherein the third boom portion pivots with respect to the second boom portion about a second axis that is substantially perpendicular to the first axis, and wherein the boring cutter head rotates with respect to the second end of the boom about the rotary axis. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24)

25. A cutter head for boring through a wall, the cutter head comprising:
-
a rotary union defining a rotary axis and supporting the cutter head for rotation about the rotary axis; a first arm including a first end, a second end, and at least one disc cutter, the first end being coupled to the rotary union, the first arm extending from the first end toward the second end in a direction that is substantially perpendicular to the rotary axis, the at least one disc cutter being coupled to the first arm and oriented to engage the wall; and a second arm angularly spaced apart from the first arm, the second arm including a first end, a second end, and at least one disc cutter, the first end being coupled to the rotary union, the second arm extending from the first end toward the second end in a manner that is substantially perpendicular to the rotary axis, the at least one disc cutter being coupled to the second arm and oriented to engage the wall. - View Dependent Claims (26, 27, 28, 29, 30, 31)
