This handheld sewing machine was invented by Adin Mayo Barber. He patented it on October 21, 1884. The machine was produced by the American Hand Sewing Machine Company (Am.H.S.M.Co.) of New York. Adin was a resident of Bridgeport, Connecticut so, as a current denizen of The State, I'm especially particular to this machine.
