Howe secures U.S. sewing-machine patent
Labels: Elias Howe, LockstitchElias Howe Jr. received a major U.S. patent for a sewing machine using a lockstitch (a durable stitch made by locking two threads together). His design helped make machine sewing practical and set off years of competition and lawsuits over who controlled key ideas. These patent fights shaped how quickly sewing machines spread into shops and homes.
