Title
American Powder Mill - Wheel Mill
Description
This photo was taken during the dismantling of the wheel mill. Each of the wheels weighed 7 tons. The cross shaft and crown gear weighted 3 tons making a total of 17 tons. The large crown gear had wooden teeth to avoid the friction or sparking of metal to metal, a common cause of the many explosions that occurred in the various mill buildings.
