ABSTRACT:
This invention relates to a winch and clutch assembly having a spool about which a line is to be wound and unwound. An electric motor is mounted within the spool and has a housing and drive shaft operable in the forward and reverse directions. A concentric ring is mounted to and rotates with the spool and a driving gear surrounds the concentric ring, the two having concentric adjacent surfaces. A gear train operatively connects said motor shaft to the concentric driving gear, and a clutch assembly is operatively located between the concentric driving gear and the driven concentric ring, which is selectively engaged and disengaged in response to the direction of rotation of the concentric driving gear so as to produce rotation of said spool in response to operation of said motor in a forward direction when said clutch assembly is engaged.
