James Henry Northrop (born May 8, 1856 – died December 12, 1940) was an important inventor. He was born in Keighley, West Yorkshire, United Kingdom. He is best known for inventing the Northrop Loom, which changed the textile industry.
Northrop moved to Boston, Massachusetts, in 1881. He worked for George Draper and Sons in Hopedale, Massachusetts. By 1898, he had created many inventions. Some of these were used in his famous loom. He retired at age 42 and passed away in Santa Ana, California, when he was 84.

Inventing the Northrop Loom
During the Industrial Revolution, inventors created many new machines. These machines made it much faster to produce goods. They also lowered costs because machines could do work that people used to do. Europe was a leader in these new inventions, especially in the textile industry.
Many early loom inventions came from countries like the United Kingdom and France. The United States often bought looms from Europe. But this began to change when James Henry Northrop created his special loom.
Early Inventions and Ideas
Northrop started his career in England as a mechanic and factory foreman. After moving to Massachusetts in 1881, he began working for George Draper and Sons. There, he invented the Northrop spooler guide.
He also worked on a "shuttle-charger" for Mr. Otis Draper. A shuttle is a part of a loom that carries thread back and forth. Northrop showed his first model of the device in March 1889.
He was given a loom to test his ideas. By May 1889, he realized his first idea wouldn't work. But he quickly thought of a new plan. By July 1889, his improved loom was working well. It seemed better than other designs.
The Revolutionary Loom Features
Northrop kept improving his inventions. He created a self-threading shuttle. This shuttle could load new thread by itself. He also added special spring jaws to hold the thread bobbin in place.
All these smaller inventions led to his greatest design: The Northrop Loom. This loom was a huge step forward for the weaving industry. It included his "filling-changing battery" from 1891.
When people hear "battery," they might think of power. But in this case, it was a system for changing thread. Northrop's new design allowed one loom to hold many different thread patterns. This meant the loom could switch between designs very quickly. There was almost no lost time in production.
His loom used two shuttle features and a "warp stop" system. The warp stop was developed by other people at the Draper company. It would stop the loom if a thread broke. With these features, the loom could change patterns in minutes.
Impact on the Textile Industry
The first Northrop looms were sold in 1894. They helped the textile industry reach new levels of production. By 1900, Draper had sold over 60,000 Northrop looms.
The company was shipping 1,500 looms every month. They employed 2,500 workers and were expanding their factories. Northrop's invention made weaving much more efficient and faster.
Life After Inventing
James Henry Northrop married Emily Driver. They had five daughters. Because his loom sold so well, he was able to retire at the young age of 42.
He bought a fruit farm in Santa Ana, California. There, he grew dates and enjoyed fishing.
