- Cloth Napping Machine Patent Model
- Patent No. 350, issued August 8, 1837
- Benjamin Swasey of Mount Vernon, Maine
- Swasey’s patent concerned the setting of teazles ( thistle-like plant heads) in the wires of the large napping cylinder. He also claimed certain springs and levers that shifted the cloth rollers in and out of gear. This shifting of the cloth rollers caused the cloth to come in contact with the teazles as the cloth was wound forward and then disengaged the cloth from the teazles as the cloth rewound.
- In this way, the cloth could roll from one cylinder to another as long as necessary to ensure a well-napped surface. Also, the shifting of gears did not require a person to match and unmatch the gears. Friction bands on the ends of the cloth rollers, together with hanging weights, kept tension on the cloth even.
