Curve for Drawing a Hyperbola, Keuffel & Esser 2182

Description:

This small, flat unpainted wooden pear wood curve has a hyperbolic top edge and a straight bottom. There are two holes along the axis. A mark on one side reads: 2182. Another mark on the same side reads; KEUFFEL & ESSER (/) N.Y.

Keuffel & Esser’s model 2182 was a set of pear wood curves of hyperbolas in eight sizes, ranging from 2 to 5 1/2 inches in depth. This is the 3 ½ inch size. Keuffel and Esser sold ellipses, hyperbolas and parabolas made from pear wood from at least 1892 until at least 1913. By 1921, such curves were available from K & E only in xylonite.
