Daniel Treadwell

Daniel Treadwell (October 10, 1791 – February 27, 1872) was an American inventor, born at Ipswich, Massachusetts. Amongst his most important inventions are a hemp-spinning machine for the production of cordage, and a method of constructing cannon from wrought iron and steel.

His first invention, made at an early age, was a machine for making wooden screws. In 1818 he devised a new form of printing press, and in 1819 went to England, where he conceived the idea of a power press. This was completed in a year after his return, and was the first press by which a sheet was printed on this continent by other than hand power. It was widely used, and in New York City large editions of the Bible were published by its means. In 1825 he was employed by the city of Boston to make a survey for the introduction of water, and in 1826 he devised a system of turnouts for railway transportation on a single track.

He completed the first successful machine for spinning hemp for cordage in 1829. Works capable of spinning 1,000 tons a year were erected in Boston in 1831. Machines that he furnished in 1836 to the Charlestown Navy Yard made all the cordage for some time for the U. S. Navy. These machines were used in Canada, Ireland, and Russia. One of them, called a circular hackle or lapper, was generally adopted wherever hemp was spun for coarse cloth.

In 1835 he perfected a method for making cannon from wrought iron and steel, resembling the process that was subsequently introduced by Sir William Armstrong. He patented it and received government contracts, but the great cost of his cannon prevented a demand for them.

In 1822, in conjunction with Dr. John Ware, he founded the Boston Journal of Philosophy and the Arts. From 1834 to 1845, he occupied the chair of Rumford professor at Harvard. Also, theology was one of his interests.

He was one of Henry Wadsworth Longfellow's circle of friends, and is the theologian of the Tales of a Wayside Inn.

He died in Cambridge, Massachusetts.
