D-???? REFUSE COMPACTION APPARATUS Abstract of the Disclosure A refuse compacting apparatus having a container for storing refuse under pressure, a loading hopper and a passage leading from the hopper into the container. A narrowed throat in the passage is positioned at a point intermediate that of enlarged openings from the passage into the hopper and the storage container. Refuse compacting means are positioned to sweep through the hopper to compact refuse and move the refuse from the hopper through the passage into the container. As the refuse moves through the passage the refuse is squeezed and is subjected to high localized pressures as the refuse passes through the narrowed throat. A refuse compacting apparatus having a container or storage body for storing refuse under pressure an ejection panel movable in the storage body, a loading hopper a passage with a narrowed throat and packing panels movable in the hopper on a cyclic basis. Refuse is stuffed at high pressures into the narrowed throat in successive cycles of movement of the packing panels and is churned fragmented and compacted during such stuffing operation. The refuse is then directed through the passage into the storage body where it is stored at reduced pressures. A servo operation is then provided to control optimally the compacting action on the refuse in the passage by controlling the pressure exerted by the refuse in the storage body. Thus when the pressure exerted by the refuse against the ejection panel reaches a first particular value the e ejection panel is moved in a direction to relieve such pressure. -1- The movement of the ejection panel occurs on an incremental basis until the pressure of the refuse against the ejection panel decreases to a second particular value lower than the first particular value. A refuse compacting apparatus having a storage body for refuse and a movable panel positioned within the storage body. A support member is provided for the movable panel, which member has a movable end and a fixed and with the fixed end pivotally connected to the storage body. A line connects the movable end to the movable panel such that the movement of the panel causes pivotal movement of the support member. Means are provided to transmit a force to the movable panel from a point on the support member which is intermediate the fixed end and movable end. Thus, as the panel undergoes move- ment within the storage body, the support member undergoes rotational movement with the intermediate point on the support member moving in an arcuate path in the direction of movement of the movable panel. A refuse compacting apparatus having a container for storing refuse under pressure and a loading hopper in communica- tion with the storage container. Refuse compacting means are positioned to sweep through the hopper to compact refuse and to move the refuse from the loading hopper into the storage container. A retainer panel is positioned to move between an opened and a closed position. With the retainer panel in its closed position, the retainer panel impedes the flow of refuse from the container into the hopper. In its opened position the retainer panel permits the flow of refuse from the hopper into the storage container. Control means are provided to move the retainer panel to all opened position while moving the refuse compacting means through the hopper to move refuse into the storage container and to move the retainer panel to -2- a closed position while returning the refuse compacting means to a position to begin sweeping through the hopper. A refuse compacting apparatus having a container for storing refuse under pressure a loading hopper in communica- tion with the storage container and a packing panel mounted to sweep through the hopper to compact refuse therein and to move the refuse from the loading hopper and into the storage container. The loading hopper includes a curved inner surface and a sill over which refuse is inserted into the hopper. The edge on the packing panel is positioned adjacent to the curved inner surface as the packing panel sweeps through tile loading hopper. Means are provided to maintain a minimum distance between an edge on the packing panel and the curved inner surface at a point adjacent to the sill which distance is slightly greater than the septh of the human finger. The distance between the edge on the packing panel and the curved inner surface is then increased slightly after the packing panel moves past the sill in sweeping through the hopper. The minimum spacing between the edge of the packing panel and the inner surface at the sill reduces the level of forces applied to the sill area during packing of refuse while also protecting the worker's fingers. The increases spacing between the edge on the packing panel and the curved inner surface as the panel sweeps through the loading hopper provides a gripping force to refuse caught between the edge and the inner surface such that refuse is pulled over the sill. and into the hopper as the panel sweeps through the hopper. A refuse compacting apparatus having a panel positioned for working movement in a first direction a /// /// -3- D-1101 relatively large first hydraulic motor for driving the panel in the first direction and the panel undergoing return movement in a second direction with a relatively small hydraulic motor driving the panel in the second direction. Means provide pressurized hydraulic fluid for driving the first and second hydraulic motors with the first and second hydraulic motors being mechanically interconnected such that meovment of the first motor to drive the panel in said first direction causes movement of the second motor in a direction opposite to its move- ment in driving the panel in said second direction. Similarly movement of the second motor to drive the panel in said second direction causes movement of the first motor in a direction opposite to its movement to drive the panel insaid first direction. The first motor has a first opening and a second opening and the second motor has a first opening and a second opening. Means are provided to connect the second opening of the first motor with the second open- ing of the second motor and means are provided to connect the second opening of the first motor and the second opening of the second motor to sump means. Valve means are positioned between the first and second motors and the means to supply pressurized hydraulic fluid with the valve means having a first operative position to direct hydraulic fluid to the first opening of the first motor to cause movement of the first motor to drive the panel /// /// -4- in the said first direction. The valve means in its first operative position also transmits hydraulic fluid from the first opening in the second motor to the sump means as the second motor moves in a direction opposite to its movement to drive the panel in said second direction. Hydraulic fluid flowing from the second opening of the first motor may flow into the second opeing of the second motor and may also flow into the sump as the first motor moves to drive the panel in said first direction. The valve means has a second operative position to direct hydraulic fluid to the first opening of the second motor to cause movement of the second motor to drive the panel in said second direction while also causing movement of the first motor in a direction opposite to its movement in driving the panel in said first direction. The valve means in its second operative position transmits hydraulic fluid from the first opening of the first motor to the sump and means interconncet the first and second opening of the first motor which means are actuate when the pressure of htdraulic fluid supplied to the first opeing of the second motor reaches a predetermined pres- sure level to permit hydraulic fluid to flow from the first opening of the first motor into the second opening of the first motor. The second motor therefore, acts as an accumlator for hydraulic fluid from the first motor as the first mot
