Abstract
Abstract A waste mangler system, optionally provided with classification means, for processing garbage, municipal waste, and the like whereby to mangle or break up compacted garbage and other materials, break open bags and bales, and otherwise treat the refuse for a flailing-type reduction. The machine is vertically oriented and includes a rotor having rapidly revolving cross-arms, mounted to a central shaft, which are provided with rigid impact blades and flail elements. The impact blades include rearwardly tapered leading edges so that debris may slide outwardly thereon under the action of centrifugal force to approach the area of reduction proximate the flail elements used. The material descending through the drum of the machinery is deposited down to suitable conveyer means that may be coupled to air classification or other means for material separation and further processing.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
101 words
Waste mangler structure including, in combination, essentially vertically disposed cylindrical structure, and a rotor journalled for rotation centrally within said cylindrical structure, said rotor having auger means cooperable with said cylindrical structure for forcefeeding received materials downwardly within said cylindrical structure, said rotor also having rigidly affixed cross-arm means disposed beneath said auger means for impact-loosening and reducing compacted materials received from said auger means, and drive means coupled to said rotor for revolving the same, said cross-arm means comprising a series of inner, impact ripper blades and a series of outer flail chains respectively secured to said impact ripper blades.
Claim 2
Dependent Claim
101 words
Waste mangler structure including, in combination, essentially vertically disposed cylindrical structure, and a rotor journalled for rotation centrally within said cylindrical structure, said rotor having auger means cooperable with said cylindrical structure for forcefeeding received materials downwardly within said cylindrical structure, said rotor also having rigidly affixed cross-arm means disposed beneath said auger means for impact-loosening and reducing compacted materials received from said auger means, and drive means coupled to said rotor for revolving the same, said cross-arm means comprising a series of inner, impact ripper blades and a series of outer flail chains respectively secured to said impact ripper blades.
Claim 3
Dependent Claim
26 words
The structure combination of claim 1 wherein said cylindrical structure is provided with cross-brace support means for supportingly journalling said rotor at a lower extremity thereof.
Claim 4
Dependent Claim
27 words
The structure of claim 1 wherein said cylindrical structure includes a side access opening proximate said auger means, and a hopper secured to said side access opening.
Claim 5
Dependent Claim
32 words
The structure of claim 1 wherein said rotor includes a central shaft, said cylindrical structure having thrust bearing means supportingly journalling said central shaft for central axial rotation within said cylindrical structure.
Claim 6
Dependent Claim
24 words
The combination of claim 1 wherein said rotor has transverse pocket structures, said ripper blades being seated within and secured to said pocket structures.
Claim 7
Dependent Claim
77 words
The combination of claim 1 wherein said rotor comprises a shaft having a longitudinal axis, said cross-arm means comprising a series of mutually vertically spaced cross-arm structures having said impact ripper blades secured to said shaft and extending radially outwardly therefrom a distance at least one-half the distance from the axis of said shaft to said cylindrical structure, said flail chains being secured to said impact ripper blades proximate the outer extremities of said impact ripper blades.
Claim 8
Dependent Claim
18 words
The structure of claim 6 wherein said impact ripper blades have leading edges which are outwardly tapered rearwardly.
Claim 9
Dependent Claim
118 words
In combination, a tubular structure having a feed end and a discharge end, a rotor centrally journalled within said tubular structure and having a longitudinal axis of revolvement, said rotor including an auger proximate said feed end and cooperable with said tubular structure for positively advancing materials fed into said feed end in a direction toward said discharge end, said rotor also being provided with radially extending rigid arms downstream from said auger and having outer extremities and also flexible elongate flails secured to said rigid arm outer extremities, the overall length of said arms with said flails exceed the distance between said longitudinal axis and said tubular structure, whereby said flails can impinge against said tubular structure.
Claim 10
Dependent Claim
118 words
In combination, a tubular structure having a feed end and a discharge end, a rotor centrally journalled within said tubular structure and having a longitudinal axis of revolvement, said rotor including an auger proximate said feed end and cooperable with said tubular structure for positively advancing materials fed into said feed end in a direction toward said discharge end, said rotor also being provided with radially extending rigid arms downstream from said auger and having outer extremities and also flexible elongate flails secured to said rigid arm outer extremities, the overall length of said arms with said flails exceed the distance between said longitudinal axis and said tubular structure, whereby said flails can impinge against said tubular structure.
Claim 11
Dependent Claim
13 words
The combination of claim 8 wherein said arms have rearwardly tapered leading edges.
