Not quite — pulleys and the lever were used long before the Industrial Revolution; the cotton gin was invented during the Industrial Revolution era.

- Lever: one of the six classical simple machines; known and used in ancient Egypt and Greece (Archimedes wrote about levers).
- Pulley: ancient device used for lifting (Egyptian and Mesopotamian construction, Greek and Roman cranes).
- Cotton gin: invented by Eli Whitney in 1793 in the United States — after the Industrial Revolution had already begun in Britain and generally considered part of the broader Industrial era rather than a pre‑Industrial technology.

Other machines used before the Industrial Revolution: water wheels, windmills, treadle-operated looms, spinning wheels, simple cranes, gears and clockworks, and bellows for furnaces.
