Abstract

See full text

A chalk line end being comprised of two flat members (12a and 12b) set parallel at a slight distance from one another and bent and fused together along at least one shared edge to form a main body (10), containing a tear-shaped aperture (18) and towards one end a smaller aperture (22) which the chalk line (24) is tied through. A main tab formed by a section of at least one of said flat members bent essentially perpendicular to said main body. A blade (14), containing a similar tear-shaped aperture (18), is sandwiched between said two flat members of said main body, and pivotally attached (20) to said main body towards one end. A means for grasping (26) on said blade at the opposite end from the pivotal connection allows the user to grasp said blade between thumb and finger and rotate it out through a long open edge of said main body, until a fused section of said flat members stops it when the blade edge (30) is at an approximate ninety-degree angle to said main body. The user can then rotate the invention on the axis of said chalk line from its position in normal use, and hook it securely on a rounded or tapered edge engaging. A chalk line end of this type also allows the user to pop a line at an angle other than ninety-degrees off the edge of a sheet of material without the aid of a helper, nail or additional tools. The present invention, therefore, represents a significant and novel improvement over prior art chalk line ends.
