Abstract:
A tool for developing patterns wherein the tool comprises first, second, and third elements used in combination with a retractable tape measure, said tape measure comprising a perpendicular tab disposed at the zero end of a measured scale wherein the scale is retractively coiled within a housing, said housing having a belt clip and means for locking said scale at preferred measurements; wherein said first element comprises:a releasable pilot comprising a cylindrical tube perpendicularly disposed at the center of a magnetic base, said tube disposing a ferro metal pin wherein the pin has a point shaped at one end for cooperating with a center punched indentation, said indentation defining an axis point defined on a ferro metal surface, wherein said pin cooperates with said tube and base, permitting the user to position and secure said pilot precisely at said axis point, wherein said pilot cooperates with said second element comprising:a releasable clip defining a pivotal bracket wherein the pivotal bracket comprises opposed side walls perpendicularly disposed at a base, said base having first and second apertures wherein said first aperture defines a narrow slit for cooperating with said tab to fasten said pivotal bracket to said tab whereby said opposed side walls cooperate with said scale to facilitate fixed alignment of said pivotal bracket, tab, and scale, wherein said second aperture defines a through hole for connecting said pivotal bracket to said pilot, permitting the user to pivot said tape measure about said axis point , wherein said tape measure cooperates with said third element comprising:a releasable clip defining a marker holder for fastening a marking instrument to said housing, said marker holder having front and rear sides disposing first and second channels and a receptacle, said receptacle disposing a mechanical fastener for fastening a marking instrument to said holder, wherein said first channel cooperates with said belt clip to fasten said marker holder to said housing whereby said second channel cooperates with said scale and housing to facilitate fixed alignment of said marker holder, scale, and housing, whereina. said marker holder and pivotal bracket are fastened to said tape measure,b. a marking instrument is fastened to said marker holder,c. said pilot is secured at said axis point,d. said pivotal bracket is connected to said pilot whereby said marking instrument engages said surface, permitting the user to draw circles, arcs, or intersecting arcs for developing patterns on a ferro metal surface.
