Abstract
Upper and lower sheet carriages are rollingly supportable on upper and lower pairs of horizontal rails respectively. Each carriage supports a stack of sheets for a copying machine or the like. A drive comprising endless chains rolls one of the carriages to a lift position above an elevator and the other of the carriages to a loading position spaced from the elevator. The elevator is raised to lift a carriage from the lift position to a sheet feed position above the upper rails. The spacing between the lower rails is sufficiently smaller than that between the upper rails that the lower carriage may be raised through the upper rails by the elevator.
