ABSTRACT An elevator for farm produce or other articles includes a pair of continuous entrainments each having a series of spaced members, such as rods or rollers, supported by continuous bands. One entrain- ment is mounted within the other and the inner entrainment is slack over an ascending section so that it normally sags towards a corresponding section of the outer entrainments. When the entrainments are driven, material is picked up by the outer entrain- ment as it passes around inside a hopper. This travels up the ascending section whereby the slack section of the inner entrainment moves away from the correspond- ing section of the outer entrainment so that the material is elevated as a rising column. The inner entrainment takes up a natural spacing from the outer entrainment over the elevating sections. The lower end of the inner entrainment may form a converging inlet to assist initial elevation and its upper end may form a diverging outlet to assist in releasing the material at an outlet. The lower end of the inner entrainment may include an idler which is mounted on a radius arm or which is supported at each side in a slot or groove. Conveyors are also described for moving material from a heap into the inlet or hopper of the elevator and for moving material away from the outlet of the elevator.
