Abstract

A ruler for draws or measurements of circle, straigth line, and angle. The line drawing or measuring is sliding belong in the ruler's track; which is at middle and parallel on the ruler's length. These techniques are combined for a simple ruler.

Description

    BACKGROUND OF THE INVENTION Field of the Invention
  • Description of Related Art including information disclosed under 37 CFR 1.97 and 1.98.
  • “Not Appliction”
    • BRIEF SUMMARY OF THE INVENTION
  • The general idea of the Professional compass-Rulers is showing the easily to compares of the SAE and Metric Unit for the measurement, sketch, or use as a compass for drawing a circle.
  • The ruler's technique is combination of the straigth ruler, protractor, and compass to become a simple ruler for sketch or draw the line belong in the ruler's track at middle and parallel on the ruler's length.
    • BRIEF DESCRIPTION OF THE SEVERAL VIEWS OF THE DRAWING(S)
  • “Not Applicable”
    • DETAILED DESCRIPTION OF THE INVENTION
  • The Professional Compass-Rulers is a combination of the techniques of compass, protractor and ruler; which uses for finding, drawing or measuring of an angle, circle or straigth line at the central of the ruler's length.
  • The technique drawing the lines is the pen travel belong in the ruler's track through on the drawing paper. The ruler's track is straigth from O dimension to the end of the ruler's length.
  • For finding or drawing is starting from the central line or the ruler's track at 180 or O and then reading the number of an angle. If the angle is larger than 180 on the left of a central line, the degree appear on the protractor scale is as the same of the degree at the opposite straigth to another side below of an axis; add these numbers for the degree of an angle.
  • The Professional Compass-Rulers may use for compass to drawing the circle which have the radius within on the ruler's track. For drawing a circle; the drawer is hold down the spindle screw, this point is center of the circle, and then sliding the drawing point belong in the ruler's track for a radius and swing the ruler to make a circle.
  • The material for reproduction of a Professional compass-Ruler may be made by cleared mica, thin wood or stailess steel; and the ruler's track is made by magetic for easily slide or clutch on tight when drawing.
