This invention is about a string line holder, used by construction workers for aligning construction units, that is inexpensive to make because of its simplicity in structure and its material which string line holder, after the string line is used up or defrayed, can be completely disposed of and replaced by another inexpensive string line holder of the same structure. The string line holder is made from a cylindrically shaped reel or spool on which the string line is wound and has an elongated handle which can be entirely inserted within a cylindrical passageway through the reel or spool and can be partially withdrawn from the cylindrical passageway such that the reel or spool can be rotated around a portion of the elongated handle. The string line holder, including the reel or spool and the elongated handle, is constructed from an inexpensive material such as cardboard or plastic.
A string line holder comprising an elongated cylindrically shaped reel or spool with a cylindrically shaped passageway there through, wherein said elongated cylindrically shaped reel or spool has a proximal end and a distal end and means within the cylindrically shaped passageway for preventing said handle from being pulled completely out from said reel or spool, a string line enwrapped there around, an elongated cylindrically shaped handle being slidable within and slidable outside of said cylindrically shaped passageway of said reel or spool, said reel or spool being rotatable around said handle, and said reel or spool and said handle being made from cardboard or plastic.
The combination of an elongated cylindrically shaped reel or spool and a cylindrically shaped handle, said elongated cylindrically shaped reel or spool having an elongated cylindrically shaped passageway therethrough wherein said cylindrically shaped handle is wholly slidable within said cylindrically shaped passageway and partially slidable outside of said cylindrically shaped passageway whereby said cylindrically shaped reel or spool is rotatable around said cylindrically shaped handle, said cylindrically shaped reel or spool having a means within said cylindrically shaped passageway for preventing said cylindrically shaped handle from being slidable completely out from said reel or spool.
