Abstract:
1. A parallel line level accessory attached to a carpentry level and configured to produce a straight line marking on a surface, the parallel line level accessory comprising: a set of two bracket fasteners that attach to opposing ends of the carpentry level, said ends being ends of the carpentry level along the long axis; a line alignment guide that constrains an extension path of a line passing through a hole of the alignment guide to a path that is parallel with the long axis of the carpentry level; a container comprising a surface marking substance and a line, said line for producing a line of surface marking substance on the surface when the line is extended through the hole of the line alignment guide and between the opposing ends of the carpentry level; a rotating wheel that removes slack from the line by winding the line until a threshold tightness is exceeded, wherein the threshold tightness is sufficiently tight for a person to snap the line to apply the line of surface marking substance to the surface; and a pulley around which the line is wrapped when extended out from the container, said line wrapping around the pulley back to the rotating wheel.
