Abstract
A trash compactor is provided with manual controls for causing a compacting cycle and additional clock timer operated controls which can operate the compactor ram through a cycle with an extended delay period after a compacting stroke at some time of day when the compactor is unlikely to be in use for a substantial length of time.
Claims3
A control for a compacting machine having a receptacle for trash material and a ram mounted for compacting movement in a compacting stroke entering said receptacle and an opposite retracting stroke to a retracted starting position, a power supply, a reversible motor connected to drive said ram, a manually initiated cycle control circuit for said motor including a directional switch connected to cause forward and reverse operation of said motor in a cycle corresponding to the compacting and retracting strokes of said ram and a starting switch for operatively connecting said directional switch with said power supply;
- the improvement comprising a timer unit having control means connected in said circuit to start said motor and to operate said ram independent of manual initiation through a compacting stroke at a predetermined time, to stop said ram upon completion of the compacting stroke, and to delay the retracting stroke of said ram for a substantial period of time.
A control for a compacting machine having a receptacle for material to be compacted and a power operated ram mounted for cyclical movement in a compacting stroke entering said receptacle and an opposite retracting stroke to a starting position removed from said receptacle,
- a reversible drive connected to said ram,
- a directional switch connected to control forward and reverse operation of said drive corresponding to the compacting and retracting strokes of said ram,
- and a control circuit incorporating said directional switch and operative to power said drive to move said ram to compact material in the receptacle and then to retract the ram and stop;
- the improvement comprising
- clock-controlled means incorporated in said circuit and operative to cause an automatic cycle of ram movement independent of manual initiation through compacting and retracting strokes and a delay period at the end of a compacting stroke of sufficient length to cause the compacted material to remain in the deformed compacted condition.
A control for a compacting machine having a receptacle for trash material and a ram mounted for compacting movement in a compacting stroke entering said receptacle and an opposite retracting stroke to a retracted starting position, a power supply, a reversible motor connected to drive said ram, a manually initiated cycle control circuit for said motor including a directional switch connected to cause forward and reverse operation of said motor in a cycle corresponding the compacting and retracting strokes of said ram and a starting switch for operatively connecting said directional switch with said power supply;
- the improvement comprising a timer unit connected to actuate said control circuit automatically at a preselected time independent of manual initiation to initiate a cycle and to stop said ram upon completion of a compacting stroke for a substantial period of time, and means operative to complete the automatically actuated cycle by retracting said ram at the end of said time period.
