Silas B. Terry of Terryville, Connecticut.
Silas B. Terry was born on February 1, 1807 (during Eli's involvement with the porter contract) and died of a heart attack on May 20, 1876. He was the youngest of eight children born to Eli & Eunice (Warner) Terry. Silas worked in various clockmaking enterprises. Unlike his father, he focused on the more expensive brass-geared clocks and was in the process of producing them as early as December of 1833. He was an inventive person and was constantly testing new designs. One of the most notable was the application of the balance wheel to clock movements. Silas was granted a patent for this on August 9, 1845. Silas was involved with several clockmaking firms, which included the S. B. Terry & Company (1852-1853) and Terryville MFG., Co. (1853-1854). In 1854, Terry went bankrupt and took a job as a general manager of the William L. Gilbert & Company of Winsted, Connecticut. In 1861, he took a job as superintendent of the Waterbury Clock Company. In 1867, he formed the Terry Clock Company in Waterbury with his sons. Silas' early clocks were well made and often had interesting movements. The evidence of his work supports the suggestion that he loved to tinker.
