ABSTRACT:
A semi-automatic roller type locking clutch for use between concentric rotational driving and driven members comprises a semi-automatic locking means and a manually activated locking means. The semi-automatic locking means is adapted to displace a plurality of rollers each disposed within a plurality of grooves circumferentially disposed on one member up onto one edge of the grooves and into contact with one edge of each of a plurality of grooves disposed on the other member whenever the driving member rotates faster than the driven member. The manually activated locking means is adapted to urge a clutch ring member slidably splined to one member into splined engagement with the other member when the members are nonrotational with respect to each other.
