Pillar and Scroll Type Shelf Clock, Made by Eli Terry, 1817-1821

Eli Terry pioneered the use of interchangeable wooden parts to make his clock works inexpensive. He combined this with a second innovation, his standardized "pillar and scroll" shelf clock, consisting of decorative pillars, supporting a scrolled top, a painted dial, above a reverse painted, decorative scene. For the first time clocks were affordable to all Americans, not just the wealthy.
