Antique Articulated Folding Brass & Wood Ruler Calculation Aid Tool / This is an Amazing old worldwide wood and brass ruler tool. A four foot folding 36" inch rule. Carpenter’s slide rule folding joint rules were in use in the 1800s by carpenters and other artisans. Both sides of the brass slide were divided into inches which allowed the user to use that part of the rule as a depth gage. The rules that are very rare, hard to find or manufactured in many instances were hand-divided by an artisan.

A ruler, sometimes called a rule or line gauge, is an instrument used in geometry, technical drawing, printing and engineering/building to measure distances and/or to rule straight lines. Strictly speaking, the ruler is essentially a straightedge used to rule lines, but typically the ruler also contains calibrated lines to measure distances.
