Abstract
This invention is for a winch having a drum for receiving a line. There are two species of the winch. In the first specie, the winch comprises a drum gear and a drum ratchet. There is a driving means for driving the drum gear and the drum. Also, there is a locking means cooperating with the drum ratchet for preventing the rotation of the drum and the unwinding of the line from the drum. In the second specie, the winch comprises a drum gear and means for driving the drum gear and the drum. Also, there are means for preventing rotation of the drum and the unwinding of the line off of the drum.
