TYPES AND USES
Dividers are instruments used for measuring distances
between two points, transferring or comparing mea-
surements directly from a rule, or for scribing an arc,
radius, or circle.
SPRING DIVIDER
A spring divider consists of two sharp points at the end of
straight legs, held apart by a spring and adjusted by
means of a screw and nut. The spring divider is available
in sizes from 3 to 10 inches in length.
WING DIVIDER
A wing-type divider has a steel bar that separates the
legs, a lock nut for setting a rough measurement, and an
adjustment screw for fine adjustments. The wing-type
divider is available in 6, 8, and 12 inch lengths.
Also available is a divider with one removable leg, so
that a pencil may be inserted.
