Howe had seen pins being made by manual process at the Alms House. Pins had long been made by hand using division of labor, as famously described by
Adam Smith in his
The Wealth of Nations. He then began a series of experiments with a view of constructing a machine for the manufacture of pins, and, after laboring during the winters of 1830—1831, made a machine that was successful as a working model, and would make pins, though in a less than perfect manner. He patented this machine in 1832, and during the same year was awarded a large silver medal by the
American Institute of the City of New York. A second machine was completed early in 1833, after which Howe traveled to
Europe for the purpose of securing patents abroad. In January, 1834, he began the building of a machine, in
Manchester, with which pins to the weight of 24,000 to the pound were made, but he was unsuccessful in disposing of his European patents, and returned to New York after an absence of almost two years. After his return the Howe Manufacturing Company was organized for the purpose of making pins with the machine he had invented. Howe took the position of general agent of the company, and continued in that capacity until 1865, being in charge of the management of the manufacturing department. Shops were initially set up in New York in 1836, but then the factory was moved in 1838 to
Birmingham, Connecticut. Late in 1838 a new "rotary machine" was developed by Howe, which he patented in 1840. For thirty years this rotary machine was used without needing any material improvement or alteration. In 1842 Howe was awarded a gold medal by the American Institute for the "best solid-headed pins," which were made on his machine. Subsequently he invented improvements in the methods used for "sheeting" pins, and was associated in the invention of means by which japanned "mourning-pins" were made. ==Patents==
