Patentcomposing-1Perhaps the earliest mechanized typesetting machine, the charmingly named Pianotype proclaims its origins. A machine had been patented in 1822 by William Church, but it appears never to have been manufactured. James Young and Adrien Delcambre patented this machine in 1840. The Mechanics Magazine of 25 June 1842 describes the system in some detail.

Here is one shown from that 1842 source, being operated by ladies. The machine actually required seven people to run it, the keyboarder and the assistant shown, who added word spaces and justified the lines, as well as two boys to replenish the supply of types in the magazine at the top of the machine, one to operate the eccentric movement of the machine, and two to distribute the types after printing had been completed.
