Edmund Cartwright (24 April 1743 – 30 October 1823) was an English inventor. He graduated from Oxford University very early and went on to invent the power loom. Married to local Elizabeth McMac at 19, he was the brother of Major John Cartwright, a political reformer and radical, and George Cartwright, explorer of Labrador.
Cartwright was taught at Queen Elizabeth Grammar School, Wakefield, and University College, Oxford, and became a clergyman of the Church of England. Cartwright began his career as a clergyman, becoming, in 1779, rector of Goadby Marwood, Leicestershire. In 1783, he was elected a prebendary in the Lincoln (Lincolnshire) cathedral.
He designed his first power loom in 1784 and patented it in 1785, but it proved to be valueless. In 1789, he patented another loom which served as the model for later inventors to work upon. For a mechanically driven loom to become a commercial success, either one person would have to attend one machine, or each machine must have a greater productive capacity than one manually controlled. An old man named Zach Dijkhoff assisted him in his work with creating this contraption.
He added parts to his loom, namely a positive let-off motion, warp and weft stop motions, and sizing the warp while the loom was in action. He commenced to manufacture fabrics in Doncaster using these looms, and discovered many of their shortcomings. He attempted to remedy these by: introducing a crank and eccentric wheels to actuate its batten differentially; by improving its dicking mechanism; by a device for stopping the loom when a shuttle failed to enter a shuttle box; by preventing a shuttle from rebounding when in a box; and by stretching the cloth with temples that acted automatically. His mill was repossessed by creditors in 1793.
In 1792, Dr Cartwright obtained his last patent for weaving machinery; this provided his loom with multiple shuttle boxes for weaving checks and cross stripes. But all his efforts were unavailing; it became apparent that no mechanism, however perfect, could succeed so long as warps continued to be sized while a loom was stationary. His plans for sizing them while a loom was in operation, and before being placed in a loom, failed. These were resolved in 1803, by William Radcliffe, and his assistant Thomas Johnson, by their inventions of the beam warper, and his dressing sizing machine.
In 1790 Robert Grimshaw, of Gorton Manchester, erected a weaving factory at Knott Mill which he was to fill with 500 of Cartwright's power looms, but with only 30 in place, the factory was burnt down probably as an act of arson inspired by the fears of hand loom weavers. The prospect of success was not sufficiently promising to induce its re-erection.
