Abstract
Abstract Apparatus for reducing in volume waste material or garbage comprising a pulverizer or hammermill receiving wet and dry organic and inorganic material, comminuting this waste material and delivering it in particle form to an auger-compacter. An air flow is likewise developed by the pulverizer and the apparatus recycles air to the pulverizer to assist in positively delivering waste material to the pulverizer. The auger-compacter has a helical screw that compacts the comminuted waste material or garbage in a compaction zone and delivers the compacted garbage reduced in volume as an output of the apparatus.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
134 words
An auger-compacter for compacting organic and inorganic waste particles randomly mixed, comprising, a tubular member, a driven auger-compacter screw disposed axially in said tubular member, having helices and a downstream end flight having a sector removed therefrom for compacting said waste particles in said tubular member, a pair of diametrically disposed blades disposed parallel to the longitudinal axis of said compacter screw extending radially of said compacter screw axis and next adjacent axially to said downstream end flight, and a pair of transverse blades transverse to the longitudinal axis of said compacter screw adjacent said parallel blades and disposed offset relative to a common plane transverse and normal to said axis, said transverse blades being disposed axially spaced from said end flight with said parallel blades intermediate said end flight and said transverse blades.
Claim 2
Dependent Claim
134 words
An auger-compacter for compacting organic and inorganic waste particles randomly mixed, comprising, a tubular member, a driven auger-compacter screw disposed axially in said tubular member, having helices and a downstream end flight having a sector removed therefrom for compacting said waste particles in said tubular member, a pair of diametrically disposed blades disposed parallel to the longitudinal axis of said compacter screw extending radially of said compacter screw axis and next adjacent axially to said downstream end flight, and a pair of transverse blades transverse to the longitudinal axis of said compacter screw adjacent said parallel blades and disposed offset relative to a common plane transverse and normal to said axis, said transverse blades being disposed axially spaced from said end flight with said parallel blades intermediate said end flight and said transverse blades.
Claim 3
Dependent Claim
43 words
An auger-compacter for compacting organic and inorganic waste particles randomly mixed according to claim 1, comprising, means to receive particles of comminuted waste organic and inorganic materials for delivery to said screw, said screw having a length thereof disposed in the last-mentioned means.
Claim 4
Dependent Claim
34 words
An auger-compacter for compacting organic and inorganic waste particles randomly mixed according to claim 1, in which each of said blades has a radial extent corresponding to the radii of flight of said screw.
Claim 5
Dependent Claim
23 words
An auger-compacter for compacting organic and inorganic waste particles randomly mixed according to claim 1, in which said helices have a similar pitch.
Claim 6
Dependent Claim
51 words
An auger-compacter for compacting organic and inorganic waste particles randomly mixed according to claim 1, including a length of said tubular member cooperative with said compacter screw having axial groovEs to reduce any tendency of a plug of compacted waste material to move rotationally while advancing axially in said tubular member.
Claim 7
Dependent Claim
33 words
An auger-compacter for compacting organic and inorganic waste particles randomly mixed according to claim 1, in which said axial grooves are spaced in a circumferential direction and are downstream of said compacter screw.
