Abstract
Abstract This invention is a refuse compactor comprising a press apparatus operating in combination with a refuse container which is removably connected to the press apparatus in tandem relation. The exit opening and the entrance opening of the press and container respectively when connected together are in registration. The refuse material is deposited in the press apparatus having therein a press platen which is reciprocally driven by mechanical link means to convey the waste into the container and is compacted therein by the continued pushing of the waste therein by the reciprocating operation of the press. A crush gate is provided for placement at the exit opening of the press apparatus to serve as an anvil against which the press platen may crush hollow containers such as bottles, cans and boxes. The crush gate is adapted to be removable therefrom at the completion of the crushing operation and the crushed material may then be conveyed into the container. When the compacting operation is completed, the entrance opening of the refuse container is closed, the container and press apparatus are disconnected and the container removed for disposing the compacted contents. A drive motor control is provided to complete the cycle of operation and is responsive to a preselected maximum amount of drive motor torque. This provides for different degrees of compaction required for different refuse materials.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
307 words
A control circuit for a compactor drive motor provided with forward and reverse power circuits, for a cycle operation, comprising: contactor switch means in said forward and reverse power circuits; an adjustable current sensitive relay means in said forward power circuit; a line of said control circuit having a mechanically operable normally closed switch means when said motor is in its forward and rearward drive cycle, and open when said motor has completed its forward drive cycle, and contactor coil means for operating said contactor switch means in said forward power circuit; another line of said control circuit having a mechanically operable normally closed switch means when said motor is in its forward and reverse drive cycle, and open when said motor has completed its reverse cycle, and contactor coil means for operating said contactor switch means in said reverse power circuit; said line of said first contactor coil means having a normally closed (contact) switch means operable by said second contactor coil means, and the line of said second contactor coil means having a normally closed (contact) switch means operable by said first contactor coil means; a second normally closed switch means in said first (mentioned) line operable to open by said current sensitive relay means in said power circuit for forward drive (; and) to abort said forward drive cycle and initiate said reverse drive cycle to completion; said normally closed switch means in said line of first contactor coil means operable to open by said second contactor coil means when said mechanically operable switch means in said another line is closed and said first mentioned mechanically operable switch means is opened; and manually operable switch means in said (lines) line of said (first and) second contactor coil means(.) operable to open during said forward drive to stop said motor at its maximum forward drive.
Claim 2
Dependent Claim
307 words
A control circuit for a compactor drive motor provided with forward and reverse power circuits, for a cycle operation, comprising: contactor switch means in said forward and reverse power circuits; an adjustable current sensitive relay means in said forward power circuit; a line of said control circuit having a mechanically operable normally closed switch means when said motor is in its forward and rearward drive cycle, and open when said motor has completed its forward drive cycle, and contactor coil means for operating said contactor switch means in said forward power circuit; another line of said control circuit having a mechanically operable normally closed switch means when said motor is in its forward and reverse drive cycle, and open when said motor has completed its reverse cycle, and contactor coil means for operating said contactor switch means in said reverse power circuit; said line of said first contactor coil means having a normally closed (contact) switch means operable by said second contactor coil means, and the line of said second contactor coil means having a normally closed (contact) switch means operable by said first contactor coil means; a second normally closed switch means in said first (mentioned) line operable to open by said current sensitive relay means in said power circuit for forward drive (; and) to abort said forward drive cycle and initiate said reverse drive cycle to completion; said normally closed switch means in said line of first contactor coil means operable to open by said second contactor coil means when said mechanically operable switch means in said another line is closed and said first mentioned mechanically operable switch means is opened; and manually operable switch means in said (lines) line of said (first and) second contactor coil means(.) operable to open during said forward drive to stop said motor at its maximum forward drive.
Claim 3
Dependent Claim
213 words
A control circuit for a compactor drive motor provided with forward and reverse power circuits, for a cycle operation, comprising: switch means in said forward and reverse power circuits; an adjustably set current sensitive means in said forward power circuit; a line of said control circuit having means for operating said switch means in said forward power circuit, and mechanically operable switch means normally closed when said motor is in its forward and rearward drive cycle; (mechanically operable switch means and means for operating said switch means in said forward power circuit;) another line of said control circuit having (mechanically operable switch means and) means for operating said switch means in said reverse power circuit (;), and mechanically operable switch means normally closed when said motor is in its forward and reverse drive cycle; said first line (of said first switch operating means) having switch means operable by said second switch operating means, and the said another line (of said second switch operating means) having switch means operable by said first switch operating means; a second (another) switch means in said first mentioned line operable by said current sensitive means in said power circuit for forward drive; and manually operable switch means in said lines of said first and second switch operating means.
Claim 4
Dependent Claim
213 words
A control circuit for a compactor drive motor provided with forward and reverse power circuits, for a cycle operation, comprising: switch means in said forward and reverse power circuits; an adjustably set current sensitive means in said forward power circuit; a line of said control circuit having means for operating said switch means in said forward power circuit, and mechanically operable switch means normally closed when said motor is in its forward and rearward drive cycle; (mechanically operable switch means and means for operating said switch means in said forward power circuit;) another line of said control circuit having (mechanically operable switch means and) means for operating said switch means in said reverse power circuit (;), and mechanically operable switch means normally closed when said motor is in its forward and reverse drive cycle; said first line (of said first switch operating means) having switch means operable by said second switch operating means, and the said another line (of said second switch operating means) having switch means operable by said first switch operating means; a second (another) switch means in said first mentioned line operable by said current sensitive means in said power circuit for forward drive; and manually operable switch means in said lines of said first and second switch operating means.
Claim 5
Dependent Claim
44 words
The control circuit of claim 2 wherein said manually operable switch means in said line of said second contactor coil means is further characterized as being operable during the forward drive cycle to arrest the cycle at the completion of the forward drive cycle.
