An Instrument for the Draftsman, Engineer, Architect, Map-Maker and Navigator A Modern Device for Accurate Lay-Out Work, Graduations Read to 1/1000 of an Inch, Plainly Visible Without the Aid of a Glass Micro-Rule, as its name implies, is a rule to measure minute distance. Working on an entirely new principle, it provides a means to readily measure and lay out distances to 1/1000 of an inch without eyestrain and without the use of a glass. The graduation lines on the scale end in ‘V’ shaped notches and with the aid of a pricker the distances are transferred to the paper, or other medium, as fine dots. When measuring distances between lines, the lines are centered in the ‘V’ notches and the distance is read off the scale in thousandths of an inch. This action is so quick and positive it must be seen to be appreciated. Micro-Rule enables the draftsman to make accurate scale lay-outs quiclky and accurately and to measure distances as readily. Micro-Rule can be used for laying off angles. With a base line off ten inches and using a table of tangents, angles can be laid off to minutes. Micro-Rule can be used in place of a proportional divider
