Abstract
Abstract The compactor features a vertically reciprocable compacting ram unit shielded externally in its compacting stroke. A bag is supported beneath the ram by a relatively rigid but movable holder; and in one version this holder is a pivoted one. In another embodiment it is a bodily movable, dolly-type. In a dual bag installation, the ram unit shifts between two side-by-side holders as the bag contents are successively compacted. The contents reach the bag through a hopper unit which is vertically shiftable relative to the holder in a rather limited stroke. The ram is pneumatically operated by a vertically acting piston in a fixed cylinder; the hopper is operated up and down by a pneumatically powered cable and pulley arrangement in one adaptation, while in another form it is operated by mechanical link means; and the ram unit is reciprocated horizontally by a pneumatic unit.
