Barker lever

Barker lever

The Barker-lever is named after Charles Spackman Barker (1804-79), engineer and organ-builder. This lever, multiplying the force of a finger on an organ key, allowed for the development of larger, more powerful organs still responsive to the human hand. These larger organs first flourished in France, e.g., the organ produced by Cavaillé-Coll at St. Sulpice.

A similar lever was developed by David Hamilton in 1835, and there has been debate whether Barker stole the design. The rest of Barker's career was undistinguished.
