ABSTRACT:
A chalk line device for storing and dispensing a chalk line, and also functioning as a plumb bob and arc scribing instrumentality. The device includes a housing formed of a pair of cooperating side plates which define a chalk and reel-receiving chamber having openings at opposite ends thereof. A centrally mounted chalk line reel is rotatably mounted within the chamber between the end openings. An arc scribing disk is mounted at one end of the chamber to project partially through one of the end openings, and a chalk line is extended from the reel through the opening at the other end of the chamber.
