Parallel Rule

   Also found in: Wikipedia 0.01 sec.
Parallel Rule 

a device for uniform hatching, used in drafting. The principal elements of a parallel rule are a straightedge with a protractor attachment, a fastening yoke, a rod, and a shift lever with a return spring. When the lever on the rod is pressed, the rod carrying the yoke with the straightedge is moved by a predetermined step ranging from 0.2 to 10 mm. The yoke may be fastened at any point on the rod up to a distance of 100 mm. The protractor attachment has a stop that allows the straightedge to be set at an angle from 0° to 180°. Self-contained parallel rules are attachable to any spot on the drawing by means of pins; other types are made in unit with drafting machines.
