A pivoted catch designed to fall into a notch on a ratchet wheel so as to allow movement in only one direction (e.g. on a windlass or in a clock mechanism), or alternatively to move the wheel in one direction
A pawl is a sort of catch that fits into a ratchet wheel and pushes it around, or it may be used as a catch to prevent the backward motion of a windlass or the wheel on a derrick.
A pivoted tongue, or sliding bolt, on one part of a machine, adapted to fall into notches, or interdental spaces, on another part, as a ratchet wheel, in such a manner as to permit motion in one direction and prevent it in the reverse, as in a windlass; a catch, click, or detent
a hinged catch that fits into a notch of a ratchet to move a wheel forward or prevent it from moving backward
A catch device attached to the loom frame which falls to catch into a rachet tooth to keep the rachet from rotating
A spring-loaded part that engages a set of teeth when moving in one direction, but slides over them when moving in the other direction The pawls in a freewheel make a ticking sound when a bicycle coasts Most freewheels have two or three pawls
A hinged or pivoted device adapted to fit into a notch of a ratchet wheel to impart forward motion or prevent backward motion
Short lug which drops into a toothed wheel or rack to prevent it from running back
A toothed device that when engaged with a ratchet bar limits the travel of the bar to one direction
A member of a latch that can be caused to engage the abutments of the rotor and to inhibit relative motion between the two parts except in one direction Also called a catch
