Bryant Grinder

Bryant is a brand of machine tools. A division of Vermont Machine Tool, Bryant specializes in the grinding field, building grinding machines with computer numerical control (CNC).

Bryant began as an independent machine tool builder. The Bryant Chucking Grinder Company was founded in 1909 and was an independent company for its first half century, during which time it was widely known in the machining industries by the colloquial name Bryant Grinder. In 1958, it was bought by Ex-Cell-O Corporation, another prominent machine tool builder, and became a subsidiary. In 1986, Ex-Cell-O and its subsidiaries, including Bryant, were purchased by Textron. In 1988, Textron sold Bryant Grinder to the Goldman Group, a financial investment group. In 2002, Bryant was purchased by Vermont Machine Tool, where it has since operated as a division.

The Bryant Chucking Grinder Company was founded in 1909 by William LeRoy (Roy) Bryant, one of the machine tool entrepreneurs mentored by James Hartness of the Jones & Lamson Machine Company (J&L). Roy Bryant had joined J&L in 1897, became chief draughtsman in 1899, and was chief engineer by 1905. While working on tooling for chucking lathes, he invented a multispindle grinder for second-operation work, which he patented (U.S. Patent 925,867). He took Hartness's advice and formed a company to build his grinders, and the Bryant Chucking Grinder Company joined J&L as one of several firms that made Springfield, Vermont an important center for machine tools and their tooling, such as accessories and cutting tools. (Others were the Fellows Gear Shaper Company and the Lovejoy Tool Company). Hartness helped finance the Bryant venture and was the firm's first president; Roy Bryant afterward assumed the post.
