Leading the Field

Vermont farmers were prolific inventors. Their inventions ranged from beehives and corn grinders to horse powers and hay rakes. Many of these machines were patented and manufactured for sale beyond Vermont’s borders. Successful Vermont manufacturers included A.W. Gray of Middletown Springs, Stoddard Manufacturing of Rutland, and the Vermont Farm Machinery Company of Bellows Falls, which made the well-known Cooley Creamer, Davis Swing Churn, and the U.S. Cream Separator.

The Cooley Creamer was invented and  patented by William Cooley of Waterbury in 1877. Cooley sold his patent to the Vermont Farm Machinery Company. The Cooley Creamer, which used cooled water to separate cream from milk, was made in several different sizes and became a best seller. By the end of the 1880s it was used on a majority of New England farms. The water-sealed Cooley system was succeeded by the centrifugal-type separator by the end of the nineteenth century. The Vermont Farm Machinery Company’s U.S. Cream Separator and the Swedish DeLaval separator became two of the most popular brands.
