Abstract
Abstract A vertical refuse compactor in which the ramming piston used to compact the refuse also ejects the refuse from the compactor after it has been compressed into a reduced bale. A vertical tubular housing is held in place through structural members and contains the hydraulically operated ramming piston. Refuse enters the ramming chamber from a hopper and through an opening below the piston when retracted. A door at the bottom of the tubular cylinder serves simultaneously as the ejecting door and the base upon which the refuse is compacted. The door is pivotally mounted and operated through hydraulic cylinders supported by the structural members. A refuse receiving can or container located beneath the ejecting door receives the compacted bales of refuse after the door has been swung open through actuation of the respective hydraulic cylinders.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
179 words
Refuse compacting apparatus comprising in combination, a vertical substantially tubular housing having a first opening at the lower end thereof; feed means adjacent to said housing for feeding refuse into the interior of said housing through a second opening in said housing above said first opening; a telescopic piston and cylinder arranged vertically within said housing and reciprocatingly movable along a vertical path within said housing for compacting said refuse fed into the interior of said housing and ejecting the compacted mass from said housing through said first opening; door means covering said first opening when in closed position and supporting said refuse while being compacted by said telescopic piston and cylinder; suspension means for suspending said door means beneath said first opening when in closed position; and door operating means for moving automatically said door means from said first opening after said refuse has been compacted for ejection of said compacted mass by said telescopic piston and cylinder returning said door means beneath said first opening for covering said first opening after said compacted mass has been ejected.
Claim 2
Dependent Claim
179 words
Refuse compacting apparatus comprising in combination, a vertical substantially tubular housing having a first opening at the lower end thereof; feed means adjacent to said housing for feeding refuse into the interior of said housing through a second opening in said housing above said first opening; a telescopic piston and cylinder arranged vertically within said housing and reciprocatingly movable along a vertical path within said housing for compacting said refuse fed into the interior of said housing and ejecting the compacted mass from said housing through said first opening; door means covering said first opening when in closed position and supporting said refuse while being compacted by said telescopic piston and cylinder; suspension means for suspending said door means beneath said first opening when in closed position; and door operating means for moving automatically said door means from said first opening after said refuse has been compacted for ejection of said compacted mass by said telescopic piston and cylinder returning said door means beneath said first opening for covering said first opening after said compacted mass has been ejected.
