19th Century American Classical / Empire Extension Dining Table with Thomas Clark Patent Hardware Provenance: New York, USA (c. 1830–1845) A superb and impressively scaled American Classical / Empire pedestal extension dining table, attributed to a New York workshop, circa 1830–1845, retaining its original Thomas Clark patented hardware, brass casters, and all three original leaves. This rare example transforms elegantly from a 54-inch (137.16 cm) round center table to a commanding 9-foot (108-inch / 274.32 cm) banquet table. This form — round center table converting to grand banquet scale — is a hallmark of high-style New York furniture of the 1830s–1840s. The table is supported by a monumental, tapering pedestal resting on four dramatic concave scrolled feet, each fitted with deep recessed wells housing the original early brass casters. These casters and wells are distinctive, high-grade features almost never found intact. The table retains Thomas Clark’s patented brass hardware, stamped “THOS CLARK,” which was used by premier New York cabinetmakers of the period. Clark’s patented mechanisms improved the stability and alignment of extension tables, making this an especially desirable and well-engineered example. Recently restored with a museum-grade French polish, the top displays a lustrous, warm garnet tone that enhances the depth and movement of the original mahogany. The transformation is seamless when extended, supported by its original rule-joint leaves and turned mahogany extension supports. This is an investment-quality American Classical table with documented hardware, original components, and exceptional proportions — rare in both size and state of preservation.
