Abstract
Abstract Machine to draw metal (especially aluminum) cans by suction into a housing by a vacuum fan. A hose may be used to pick up cans from the ground or cans may be fed manually into the intake of the housing. The intake is at the top of the housing and in registry therewith is a vertical cylinder of expanded metal or machined from high-impact plastic, which directs the cans down through a conical hopper of high-impact plastic. Small foreign particles pass through the vertical cylinder and hopper and drop to the bottom of the housing. These particles may be collected from the housing from time to time. Dust and very small particles are drawn through the vacuum fan and collected in a filter bag. Large particles such as cans are directed from the hopper to a chute where they are shredded by revolving blades and pass into a compactor housing where they are compressed for salvage.
