Abstract: Apparatus for counting containers such as empty aluminum cans comprises a loading conveyor for feeding empty containers to a counting unit having a movable conveyor underlying spaced, parallel partitions which provide a plurality of parallel pathways along which the containers are conveyed toward a discharge zone. Upstream from the discharge zone is a metering device which overlies the containers and which precludes more than one container in any row from passing the metering device at any one time. Downstream from the metering device are counters which record the number of containers discharged from the counting unit. Containers discharged from the counting unit are conveyed to an elevated level from which they are discharged to a bin for crushing and baling.

Abstract: A wheeled trailer has a frame adapted to be coupled by a drawbar to a towing vehicle. The drawbar has a rear end capable of attachment at any one of a number of vertically spaced points to an anchor member and has an intermediate portion removably retained in an open bottom socket within which is a fulcrum. Vertical adjustment of the rear end of the drawbar effects vertical adjustment of its forward end in a manner to compensate for varying height trailer hitches on different vehicles and enable the trailer bed to occupy a substantially horizontal position. The trailer frame is capable of rocking movement about the axes of its wheels to a position in which the rear end of the trailer bears against the ground.
