Method and apparatus for waste disposal

Claim 1

In apparatus for forming a vertical void in the ground and filling said void with waste material which is compacted in the void, the combination of: a. a vertical frame having ground engaging means at its lower end which holds the frame against rotation relative to the ground; b. supporting members engaging said frame at points spaced above its lower end which also hold the frame against rotation relative to the ground; c. a vertical track on said frame; d. a cylindrical casing having an upper end and an open lower end; e. a track follower on said casing and cooperating with said track; f. an auger rotatably mounted in said casing; g. means for preventing relative rectilineal movement between said auger and casing; h. power means for rotating said auger in either of two directions of rotation; i. a lateral opening in said casing through which waste material is introduced thereunto; and j. a second lateral opening in said casing through which soil excavated by the auger is discharged, whereby said auger is rotated in one direction to form a vertical void in the ground with the soil which is removed as an incident to forming the void is discharged through said second lateral opening and the casing together with the auger is moved downwardly into the void, whereupon the auger is operated in a reverse direction while waste material is introduced into the casing through the first lateral opening to cause said waste material to be compacted in the void while the casing and auger are moved upwardly of the void.
