Abstract: The disclosure herein describes a vehicle for curbside collection of source separated recyclable materials. A dumping unit includes a box-like frame having a series of compartments to receive the separated materials and includes, along one side wall thereof, a vertically movable trough having a series of compartments receiving the recyclable materials. The trough moves upwardly along the said side wall to an upper discharging position whereby the separated materials are dumped into the compartments of the frame. A cylinder located centrally between the understructure and the frame cooperates with pin-engaged hinge points on either side or rear of the frame to tilt the frame on any one side depending on where the pins are engaged in the hinge points. Doors at the bottom of each compartment allow the discharging of the contents of the compartments whenever the frame is tilted on one side or the other.
