Description

A rare Champion patented March 15, 1921 double‑side quick‑adjustable nut wrench, measuring 8 inches long, and a terrific example of one of the more inventive early‑20th‑century adjustable wrench designs.

This patented Champion pattern features quick‑adjust jaws on both sides, allowing the user to switch instantly between two preset sizes—an ingenious time‑saving idea for mechanics and tradesmen who frequently alternated between different nut dimensions. The mechanism is smooth, the form is compact and efficient, and the 8″ length makes it a perfect pocket‑sized adjustable with real capability.

Examples of this 1921 patent are genuinely hard to find, especially in clean condition, and the dual‑jaw quick‑adjust design gives it strong appeal for collectors of early American wrench innovations.

A scarce and mechanically clever patented wrench with great character.
