This 48-spindle spinning machine, the oldest piece of cotton machinery in America, was built by Samuel Slater, and first operated by him on December 20, 1790, at Pawtucket, Rhode Island. One hundred years later, 1890, it was lent to the city of Pawtucket for exhibition at the Cotton Centenary, a celebration of the 100th anniversary of the beginning of cotton spinning by power machinery on the Western Hemisphere, and yarn was spun on it by an old man who had tended the spinning frame in the 'Old Slater Mill' when he was a boy. In 1876, it was exhibited at the Centennial Exhibition in Philadelphia, and in 1885, was lent by the National Museum for exhibition at the World's Industrial and Cotton Centennial Exposition in New Orleans. Presented by the Rhode Island Society For The Encouragement of Domestic Industry.
