Description: Bucket elevator and revolving screen made by the Jeffrey Manufacturing Company of Columbus, Ohio. Jeffrey elevators could move from 6 to 80 tons of material per hour and lift vertically material from 10 to 80 feet high. They consisted of endless chains, provided with buckets of steel or malleable iron, spaced at short, equal intervals. The buckets on the elevator were made at the Ohio Malleable Iron Company, a Columbus-based subsidiary of Jeffrey. The elevator fed crushed rock to the revolving screen. Different sizes of mesh in the revolving screen separated the rock into individual bins according to rock size. This elevator and screen were used in Delaware, Ohio, 1926. View on Ohio Memory.
