Abstract
A cutting tool for truncating elongated structural members has a frame with a pair of parallel siderails connected at a first end by a support plate and at a second end by a removable end gate, the frame having an open center adapted to receive the structural member therethrough. The truncating is performed by a fixed penetrating blade mounted on and end gate open and a driven penetrating blade slidably disposed within the frame. Thus, the end gate has at least two penetrating blades pointing in opposite directions wherein the driven penetrating blade and the fixed penetrating blade have concave cutting edges relative to one another and configured to be adjacent to one another along the travel of the driven penetrating blade.
Claims18
A cutting tool for truncating elongated structural members, said cutting tool comprising:
- a frame with a pair of parallel siderails connected at a first end by a support plate and at a second end by a removable end gate,
- the frame having an open center adapted to receive the structural member therethrough,
- a truncating mechanism comprising,
- a plurality of blades including
- a fixed penetrating blade mounted at a first side of the end gate open to the open center of the frame,
- a driven penetrating blade slidably disposed within the frame, and
- a mechanism connected to the driven penetrating blade to drive the driven penetrating blade towards the structural member to sever the structural member, and
- slidable mounts to secure and guide the driven penetrating blade on the frame to allow for movement across the open center of the frame towards the fixed penetrating blade,
- wherein the end gate has at least two penetrating blades pointing in opposite directions;
- and
- wherein the driven penetrating blade and the fixed penetrating blade have concave cutting edges relative to one another and configured to be adjacent to one another along the travel of the driven penetrating blade.
A method for cutting an elongated member, comprising:
- providing a cutting tool having a driven penetrating blade that is a substantially first flat blade slidably disposed between slidable mounts, the driven penetrating blade having a bevel on concave shaped cutting edge relative to an end gate;
- providing a cutting tool having a mounted penetrating blade on the end gate;
- mounting the blades around a pile and at a selected position along the pile with the cutting edges confronting the pile;
- and
- driving the cutting edges of the blades into a surface of the pile around the periphery of the pile.
A cutting tool for truncating elongated structural members, said cutting tool comprising:
- a frame, comprising
- two substantially parallel side rails,
- a cross member attached to and extending between one end of the side rails, and
- an end gate attached to and extending between a second end of the side rails;
- a substantially flat first blade slidably disposed between the side rails, the blade having a concave cutting edge, the concave cutting edge facing the end gate;
- a substantially flat second blade mounted on the end gate, the second blade having a concave cutting edge, the concave cutting edge facing the first blade;
- wherein said cutting edges form an opening within the frame configured to surround the elongated structural member;
- and
- mechanism for moving the first blade toward the second blade, whereby said movement causes the first blade to truncate the elongated structural member extending through said frame opening, between the first blade and the second blade.
