American inventor and manufacturer of pins.
After 20 years as a carpenter, he moved to London, England.
In the 1835 he devised and patented a machine for making pins with solid heads.
Shortly thereafter, he returned to the U.S. and sought a partner. By 1840, the pin-making firm of Slocum and Jillson was manufacturing at Poughkeepsie, N. Y. All the while, the question of packaging pins held Slocum's attention, and on 30 Sept 1841, he obtained patent No. 2,275 for a machine for sticking pins in paper.
In 1841, his machine for sticking pins in paper was patented. A sliding hopper deposited a number of pins in grooves in a plate, from where a row of wires pushed them into a folded paper. The operation was activated by a foot treadle. He had previously invented in 1838, but not patented, a machine to manufacture pins with a solid head. He formed a company to make what became known as "Poughkeepsie pins" (1839). One man tending two such machines could produce 100,000 pins in 11 hours. Slocum's pin was the first with a solid head to be made in the U.S.Until he retired, Slocum continued in the pin manufacturing business and improved his pin sticking machine.
