Abstract
Abstract An apparatus for disposing of waste materials, of either a commercial or household type, wherein the waste materials are separated for either compacting or discharge into a sewage system. Prior to discharge, a portion of the waste products are crushed and stored in a container provided in the apparatus, which container is connected to the sewage system. The remaining portion of the waste materials or the non-decomposable waste material is separated in another compartment from that being crushed so that it may be compacted and disposed of or forwarded to an appropriate treatment facility for possible recycling.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
111 words
A waste disposal apparatus which comprises means for introducing the waste material into the apparatus, means for separating the waste material into a type which is biologically decomposable and a type which is not biologically decomposable, means for grinding the portion of the waste material which is biologically decomposable, means for compressing the portion of the waste material which is not biologically decomposable, container means disposed beneath said grinding means adapted to receive the ground biologically decomposable waste material, and coupling means having one end thereof connected to said container means and the other end thereof connected to a central sewage system into which the biologically decomposable waste material is discharged.
Claim 2
Dependent Claim
111 words
A waste disposal apparatus which comprises means for introducing the waste material into the apparatus, means for separating the waste material into a type which is biologically decomposable and a type which is not biologically decomposable, means for grinding the portion of the waste material which is biologically decomposable, means for compressing the portion of the waste material which is not biologically decomposable, container means disposed beneath said grinding means adapted to receive the ground biologically decomposable waste material, and coupling means having one end thereof connected to said container means and the other end thereof connected to a central sewage system into which the biologically decomposable waste material is discharged.
Claim 3
Dependent Claim
43 words
A waste disposal apparatus in accordance with claim 1 which further includes means for introducing water into said container means, and an overflow pipe connected at one end to said container means and at the other end thereof to said central sewage system.
Claim 4
Dependent Claim
51 words
A waste disposal apparatus in accordance with claim 2 which further includes a recirculating pump which has the output side thereof connected to the lower portion of said container means and the input side thereof connected to the upper portion of said container means at a point below said overflow pipe.
Claim 5
Dependent Claim
24 words
A waste dispoSal apparatus in accordance with claim 2 which further includes a screen disposed in said container means above said water introducing means.
Claim 6
Dependent Claim
122 words
A waste disposal apparatus in accordance with claim 1 wherein said grinding means comprises a plurality of rotatable members spaced from one another so that at least a portion of the waste being processed is crushed between adjacent rotatable members and wherein each of said rotatable members has a tapered cone-like surface and is positioned such that the axis about which rotation occurs is inclined in a downward direction away from said introducing means sufficiently to cause the material which is not crushed between said rotatable members to slide thereacross and off the lowermost portion thereof, said cone-like surfaces being arranged such that the end having the larger diameter is disposed adjacent the end having the smaller diameter of the adjacent member.
Claim 7
Dependent Claim
20 words
A waste disposal apparatus in accordance with claim 5 which further includes a disinfectant dispenser disposed above said rotatable members.
Claim 8
Dependent Claim
68 words
A waste disposal apparatus in accordance with claim 5 which further includes a second container means disposed adjacent the first container means, and a vertically extending partition separating each of said container means and which has the uppermost edge thereof adjacent the lowermost portion of said rotatable members such that objects not susceptible to crushing by said rotatable members are separated and passed to said second container means.
Claim 9
Dependent Claim
57 words
A waste disposal apparatus in accordance with claim 7 which further includes a disposable bag positioned in the lower portion of said second container means for collecting the portion of said waste material passed therein, and a movable press disposed in said second container means adapted to compress the material in said bag into a compact pile.
Claim 10
Dependent Claim
31 words
A waste disposal apparatus in accordance with claim 1 which further includes a drawer at the bottom of said compressing means to allow for easy removal of the compressed waste materials.
