Abstract: A battery powered chalk line comprising a housing having a top and bottom face and side walls forming a chamber therein. A drive shaft is secured within the side walls for rotational movement and extends across the width of the chamber. A spindle is mounted on the shaft and is selectively couplable for rotation therewith. A chalk line is mounted on the spindle for being dispensed and retrieved with the rotation of the shaft. The chalk line extends through an aperture in the front end of the housing with a hook secured to the exterior end of the line. A cavity in the chamber adjacent to its front end in proximity to the aperture for coating the line with chalk powder as the line passes therethrough. A driven bevel gear forms with the spindle for rotation therewith. A motor with an output shaft with drive bevel gear secures thereto for rotation to rotate the spindle to reel in the line. Batteries within the chamber couple the motor with a switch to activate and inactivate the motor.
