Pin-making machine patent model
1841
patented by John Howe
In the early 1800s, Americans increasingly turned their attention to mechanizing labor-intensive tasks. The ensuing Industrial Revolution changed the face of transportation, manufacturing, trade, and even the landscape as Americans established mills and factories. One of John Howe's machines could produce over 20,000 pins a day, compared to the twenty pins that one man could make by hand. |
