Abstract
A hollow handle portion and a hollow barrel portion communicate with each other in a hollow housing. A first detent in the barrel portion has a first relationship for retaining a chalk in the barrel portion and a second relationship for releasing the chalk from the barrel portion. The detent is operable to the first and second relationships by a control member externally disposed on the barrel portion. A rotatable reel and a second detent are disposed in the handle portion. The second detent has a first relationship for preventing the reel from rotating and a second relationship for providing for the reel rotation. The second detent is operable to the first and second relationships by a second control member externally disposed on the handle portion. A string wound on the reel extends at a free end through an opening in the handle portion to a position external of the handle portion. A gripping member attached to the string free end provides for a manual unwinding of the string from the reel with the second detent in the second relationship. A rotary member externally disposed on the handle portion is coupled to the reel for rotation with the reel. The rotary member has a handle disposable in a first relationship flush with the rotary member and in a second relationship transverse to the rotary member. With the handle and the second detent in the second relationship the rotary member is rotatable to wind the string on the reel.
