Claim 19:
20. A snatch block comprising:
a first stationary cheek residing in a first plane on a first side of an internal space of the snatch block;
a movable second cheek residing in a second plane on an opposing second side of an internal space of the snatch block in spaced and opposing relation to said stationary first cheek, said movable second cheek being movable between a closed position and an open position;
at least one sheave rotatably supported on said first and second cheeks in the internal space therebetween, and said sheave being rotatable around a rotation axis that transversely penetrates said first and second planes; and
a crown residing at a position spaced outwardly from a periphery of the sheave in a radial direction relative to said rotation axis, thereby delimiting a swallow that remains open between the sheave and the crown to accommodate passage of a rope therethrough;
wherein the movable second cheek is spring biased into the open position and is linearly slidable between said open and closed positions along an axis lying transversely of the rotation axis of the sheave.
