Abstract
According to an aspect of the present invention, a chalk line holder has a housing, an operating mechanism on the housing, with a spool around which a supply of line can be wound and moveable relative to the housing about a first axis, and a brake assembly for the spool. The brake assembly has a ratchet element moveable with the spool about the first axis, a pawl moveable transversely to the first axis between a) an engaged position wherein the pawl engages the ratchet element to prevent movement of the spool in a first direction about the first axis and b) a disengaged position, a biasing element normally urging the pawl towards the engaged position, and an actuator to move the pawl towards the disengaged position against the urging of the biasing element.
