ABSTRACT:
The invention provides a latching mechanism including a pawl, a ratchet wheel having a recess engageable with the pawl to restrict rotation of the wheel in one direction and cam means associated with the wheel and operative on rotation thereof in said one direction to urge the pawl away from the recess. The pawl is biased solely by gravity to move toward the recess whereby to enable engagement in said recess. The gravity bias acting on the pawl will be insufficient to cause the pawl to be in a position to engage said recess when the angular velocity of the wheel is in excess of a predetermined latching velocity. The latching mechanism may be used in a winding apparatus for hose.
