Abstract
A system, a method and a collapsible and/or folding apparatus may use a wire loop to cut an object. The apparatus may have a wire loop connected to pulleys on a carriage attached to a frame. The carriage may move relative to the frame to direct the wire loop through the object. The apparatus may have arms on the carriage that may be folded and/or a kicker frame pivotably connected to the frame that may be retracted to reduce the overall size of the apparatus.
Claims20
An apparatus for cutting an object, the apparatus comprising:
- a carriage;
- a frame having a first end and a second end located opposite to the first end wherein the carriage moves on the frame from a first position at the first end of the frame to a second position at the second end of the frame;
- a first arm and a second arm each pivotably connected to the carriage;
- a first pulley connected to the first arm;
- a second pulley connected to the second arm;
- and
- a wire attached to the first pulley and the second pulley wherein the wire travels through the first pulley and the second pulley.
A method for folding a cutting apparatus for cutting an object using a wire connected to pulleys on a carriage connected to a frame wherein the carriage has a first arm and a second arm, the method comprising the steps of:
- removing the wire by adjusting one of the pulleys;
- unlocking the first arm and the second arm;
- attaching a support plate to the frame;
- folding the first arm and the second arm so that each of the first arm and the second arm contacts the support plate;
- and
- securing the first arm and the second arm to the support plate.
A system for cutting an object comprising:
- a frame;
- a carriage connected to the frame wherein the carriage moves from a first position relative to the frame to a second position relative to the frame to cut the object;
- a drive train connected to the frame and the carriage;
- pulleys connected to the carriage;
- a motor connected to one of the pulleys;
- a wire attached to the pulleys wherein the wire travels through the pulleys;
- a first hydraulic circuit to operate the motor for rotating the wire;
- and
- a second hydraulic circuit to operate the drive train for translating the carriage relative to the frame.
