The term 'American empire' applied to furnishings describes the style of c. 1825-40, which followed the Federal and preceded the Victorian. In clocks, this includes such types as bronze looking-glass, triple-decker carved, gilded and veneered, and some plain rectilinear cases. Among collectors the term 'Empire' case usually refers specifically to the two-door type of Connecticut shelf clock, having full rounded pillars flanking the larger two-section top door. The top section of this door enclosed the dial, and the lower section generally had a mirror and was flanked by mahogany-veneered corbel sections. The base of the clock was supported by turned feet dowelled into the bottom and the top splat was generally carved. Such cases were most frequently used with eight-day weight-driven brass movements, though a few are known containing wooden movements.
