Thomas died on January 29, 1859, in Plymouth Hollow, Connecticut, and was interred at the Hillside Cemetery. The company went out of business in 2009.


He died in 1859, whereupon the company was taken over by his son, Aaron, who added many styles and improvements after his father's death. He made the clock that is used in Fireman's Hall. Terry then made an assembly line to make the production process efficient for his wooden works. This allowed him to reach a wider market. Eli Terry invented affordable wooden works to replace the expensive brass works used in most clocks at the time. By the mid-1840s, he changed over to brass from wooden movements. Hitchcock’s inspiration was Eli Terry, the legendary clockmaker. In 1817, he added shelf and mantel clocks. In 1810, he bought Terry's clock business, making tall clocks with wooden movements, though he chose to sell his partnership in 1812, moving in 1813 to Plymouth Hollow, Connecticut, where he set up a factory to make metal-movement clocks. Thomas formed a clock-making partnership in Plymouth, Connecticut with Eli Terry and Silas Hoadley as Terry, Thomas & Hoadley. Although Cheney was trained as a maker of fine clocks in brass and other materials, Eli Terry, a clockmaker who had trained as a clockmaker with either Timothy or Benjamin Cheney, had just invented a method of producing the parts for wooden shelf, or pillar-and-scroll clocks that enabled them to be mass-produced using interchangeable parts. He started in the clock business in 1807, working for clockmaker Eli Terry. He was apprenticed as a carpenter and joiner, and worked building houses and barns. Thomas was born in Wolcott, Connecticut in 1785.
