Multiflex Curve by Devonics


Some drawing curves, such as those manufactured by Keuffel & Esser, sold in the same form for decades. Others proved less enduring. The Multiflex curve distributed by Devonics, Inc., of San Diego, California, is in the second category.

The rectangular, transparent plastic instrument has a flexible side adjacent to a large opening. The side moves to any of seven positions, creating several wing-shaped closed curves. A mark on the front of the instrument reads: No. 12. A paper sticker reads: DEVONICS INC. (/) BOX 7158 (/) SAN DIEGO, CA. 92107. The object fits in a clear plastic bag with a yellow paper sheet that reads in part: MULTIFLEX TM (/) 7 (/) CURVES (/) IN (/) 1 (/) 12 INCH SIZE (/) ALSO AVAILABLE IN (/) 18 INCH AND (/) 24 INCH SIZES.

According to the donor, Lawrence J. Kaam, the curve was invented by John Toth, an engineer who worked for Kaam at Numerical Control Corporation between 1961 and 1965. Toth manufactured some of the instruments but was not successful in marketing. When Kaam started Devonics, Inc., he purchased Toth’s rights and started selling the Multiplex. Devonics was in business from 1967 until 1968 and from 1970 to 1971.
