ABSTRACT:
A self contained plumb bob and ink line marker with a line capable of automatic braking and retracting, comprising a hollow housing wherein a line reel, in combination with an adjustable spring-loaded line retraction and braking mechanism, allows a flexible member to be manually extended from the reel by a tacking device for attachment of the apparatus to a reference point. The flexible member is coated with ink upon extension from the reel when the flexible member passes over an ink absorbent member enclosed inside the housing. The housing of the apparatus has a tapered point on one end and serves as a plumb bob weight for indicating verticals when the apparatus is suspended by the tacking device. For purposes of marking lines, the ink coated flexible member can be held taught between the tacking device and notches around the circumference of an aperture through which the flexible member exits the housing, pulled upwardly and quickly released to leave a clean, thin line on the adjacent surface.
