Reversing leadscrew apparatus, system and method
View Patent ↗The present invention is an apparatus, system and method for use for winding and unwinding reels having a level wind carriage adapted to lay a cable back and forth across a drum of a spool by changing travel direction when contacting a first ring and a second ring of a tripping bar respectively.
1. A winch comprising:
a frame having a first end and a second end;
a spool having a first end with a sprocket, a drum, a second end, a motor for rotating said spool, and said spool is mounted to said frame;
a leadscrew having a male threaded length, a first end rotatably attached to said frame said first end and a second end rotatably attached to said frame said second end;
a mechanical non-electric tripping bar having a length in parallel with said length of said leadscrew, a first end attached to said frame said first end, a second end attached to said frame said second end, a first spring loaded ring adjustably positioned on said length, and a second spring loaded ring adjustably positioned on said length;
a tube having a length in parallel with said length of said leadscrew, a first end attached to said frame said first end, a second end attached to said frame said second end;
a drive assembly adapted to rotate said leadscrew with said motor of said spool; and
a level wind carriage movably positioned on said length of said tube and movably joined on said male threaded length of said leadscrew by a female thread wherein said level wind is moved when leadscrew is rotated and said level wind carriage is adapted to lay a cable back and forth across said drum of said spool by changing travel direction when contacting said first spring loaded ring and said second spring loaded ring of said tripping bar respectively.
