Refrigerated railcar

In 1867, the first U.S. patent for a refrigerated railroad car was issued to J.B. Sutherland of Detroit, Michigan (No. 71,423). This described an insulated car with double walls, double roof and double floor with the space between filled with sawdust, felt or other suitable material. Ice chambers at each end of the chamber would carry about 800 pounds of ice. Hanging flaps were designed to maintain air circulation such that warmer air moving upward would then flow through the ice chamber, and thus cooled, be returned to the body of the car. Iron pipes mounted under the roof were installed for hooks carrying meat, or other edibles. Matting was positioned between the inner sliding door and outer door to keep the car as air-tight as possible.
