  • Patent number: 5444920
    Abstract: Tools for use in drafting projects such as dress making include a ruler having five scales, a five-in-one tool, and a tool having utility in the construction of darts. The five scale ruler enables its user to determine fractional lengths without resorting to arithmetic calculations. The five-in-one tool provides a 90.degree./45.degree. angle, two scaled straight edges, a hip curve, a sleeve cap, neckline, and armhole curve, and a pair of spaced apart apertures for use in making Raglan sleeves. The dart tool is a forty five-forty five-ninety triangle having equidistantly spaced apertures formed along the length of the hypoteneuse. The apertures enable use of the tool as a compass for drawing circles and semicircles.
