Abstract
Abstract A kitchen compactor for the crushing of trash and other disposable wastes is disclosed. The compactor employs a hydraulic cylinder and piston assembly which is controlled by a control means that causes water from the household water supply to flow into the hydraulic cylinder. The water pressure produces motion of the piston which activates a lever arm upon which a pressing platen is mounted. The movement of the lever arm causes the pressing platen to enter into or withdraw from a waste container. When the pressing platen enters the waste container, the waste contained therein is compressed into a small bale or package of considerably smaller volume for easier disposal.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
182 words
A kitchen compactor comprising: a casing; a removable platform having a forward wall and a base wall, said platform interfitting with said casing; roller means mounted on said removable platform to enable said platform to be separated from said casing; said removable platform being adapted to support on said base wall thereof, a trash container having an open top; hydraulic power means connectable with a household water supply, said hydraulic power means being mounted within said casing; lever means pivotally mounted within said casing, said lever means being connected with said hydraulic power means; a pressing platen attached to said lever means and being configured to enter at least partially into said trash container; and hydraulic control means operative in a first mode of operation to cause said hydraulic power means to pivot said lever means until said pressing platen enters said trash container to compress the trash therein; said hydraulic control means also being operative in a second mode of operation to cause said hydraulic power means to pivot said lever means until said pressing platen retracts from said trash container.
Claim 2
Dependent Claim

A kitchen compactor comprising: a casing; a removable platform having a forward wall and a base wall, said platform interfitting with said casing; roller means mounted on said removable platform to enable said platform to be separated from said casing; said removable platform being adapted to support on said base wall thereof, a trash container having an open top; hydraulic power means connectable with a household water supply, said hydraulic power means being mounted within said casing; lever means pivotally mounted within said casing, said lever means being connected with said hydraulic power means; a pressing platen attached to said lever means and being configured to enter at least partially into said trash container; and hydraulic control means operative in a first mode of operation to cause said hydraulic power means to pivot said lever means until said pressing platen enters said trash container to compress the trash therein; said hydraulic control means also being operative in a second mode of operation to cause said hydraulic power means to pivot said lever means until said pressing platen retracts from said trash container.
Claim 3
Dependent Claim
22 words
A kitchen compactor as defined in claim 1 wherein said forward wall of said platform forms the forward wall of said casing.
Claim 4
Dependent Claim
40 words
A kitchen compactor as defined in claim 2 wherein said forward wall of said platform includes a manually operable hopper door therein which permits trash to be introduced into said trash container while said platform remains coupled with said casing.
Claim 5
Dependent Claim
46 words
A kitchen compactor as defined in claim 1 wherein said casing includes a bottom wall portion, said bottom wall portion serving as a stop against which said platform base wall abuts, and also serving as a mounting wall to which said hydraulic power means is attached.
Claim 6
Dependent Claim
25 words
A kitchen compactor as defined in claim 4 wherein said hydraulic power means is pivotally attached at its lower end to said bottom wall portion.
Claim 7
Dependent Claim
44 words
A kitchen compactor as defined in claim 1 wherein said lever means carries said pressing platen at one end thereto, is connected to said hydraulic power means at the opposite end thereof and is pivotally mounted by a pivot passing therethrough between its ends.
Claim 8
Dependent Claim
50 words
A kitchen compactor as defined in claim 6 wherein said lever means includes a downwardly open notch betweEn said pressing platen and said pivotal mount, said notch being adapted to pass over the rear wall of said trash container as said lever pivots said pressing platen into said trash container.
Claim 9
Dependent Claim
60 words
A kitchen compactor as defined in claim 1 wherein said hydraulic power means includes a cylinder, a piston movable within the cylinder under the influence of hydraulic pressure, a piston rod attached to said piston and projecting beyond said cylinder and a clevis mounted on the end of said piston rod said clevis being pivotally connected to said lever means.
