Abstract
An improved portable winch is described including a reversing drive mechanism. The drive mechanism includes a drive bearing which is movable between two positions. In one position the bearing is able to transmit the rotational motion of the input shaft directly to an output shaft. In another position the bearing is able to reverse the rotational motion of the input shaft and transmit it to the output shaft to drive it in a direction opposite to the input shaft. The reversing drive mechanism enables the drum to be rotated in either direction, as desired.
