Abstract: A powdered chalk line dispenser comprising a housing formed from at least two mated together cover plates, which define a cavity with an opening and a threaded aperture; a spool assembly is located in said housing cavity; a chalk line is wrapped around said spool and extends outwardly of the housing through the opening in the housing; a spring and manual lever are attached to the spool to cause the spool to rotate in a direction to apply a force to the chalk line to wrap the chalk line around the spool; an aperture in said housing is internally threaded for attachment to an externally threaded chalk supply bottle which supplies chalk into the cavity for coating the chalk line.
