Line drawing tool
A line drawing tool includes a body; a reel that is rotatably provided in the body and that includes flanges on two ends of a thread winding shaft; a thread that is wound around the thread winding shaft and that is drawn out to outside of the body with powder that is enclosed in the body being adhered to the thread; and a clearance that is formed between the flanges of the reel and the body, the clearance being provided for allowing the powder that accumulates between the body and the flanges to escape.

Jam resistant chalk reel
A chalk reel includes a housing defining a chalk chamber and an opening from the chalk chamber; a spool positioned within the chalk chamber; and a line wound on the spool and extending through the opening, the line having a width of dimension X. The spool comprises an axial hub and a sidewall. The sidewall comprises a plurality of apertures extending through the sidewall from a first face distal from the axial hub to a second face proximal to the axial hub. Each of the plurality of apertures having a maximum width of dimension Y. The dimension Y is less than or approximately equal to twice the dimension X.

Reel-to-reel chalk line system and method
An apparatus and method for a reel-to-reel chalk line comprising a first housing comprising a first impregnated chalk line reel, a first rotatable crank mechanism connected to the first reel, and a first chalk bin comprising apertures for allowing the passage of a continuous impregnated chalk line. The apparatus further comprises an opposed second housing comprising a second rotatable reel, a second crank mechanism connected to the second reel, and a second chalk bin comprising apertures for allowing passage of the continuous impregnated chalk line. The continuous impregnated chalk line is reeled about the first and second reels as the respective crank mechanisms are alternately rotated forward and backward. The chalk may include a variety of substances including reactive powders, liquids, dyes, glass, minerals, plastics, ceramics, metals, and fibers. The continuous chalk line may comprise interconnected impregnated chalk lines joined by mechanical or chemical means forming the continuous impregnated chalk line.

Chalk box with end hook seating assembly
A chalk box including a housing (110) having an aperture (140), a reel assembly (120) enclosed within the housing, a string (140) having a first end operably coupled to an end hook (170) and configured to extend from the housing through the aperture and having a second end configured to be wound on the reel assembly, a chalk reservoir (160) in which the string is retained or through which the string passes prior to extending out of the aperture, and a seating assembly (180) configured to extend around at least fifty percent of the length or volume of the end hook when the string is fully withdrawn into the housing.
