A stationary chamber is located below an apron on which garbage and other refuse is dumped from collection trucks. An opening in the apron is aligned with an opening in the top of the chamber. The discharge end of the chamber is closed by a gate which slants rearward at an angle of 15.degree. to the vertical against which the refuse is compacted. The gate may be raised when the chamber is to be discharged. Reciprocating within the chamber is a platen having its upper portion slanted forward at about an angle of 42.degree.. The platen is driven by a multi-stage hydraulic ram. Loads of about 15 cu. yds. are dumped into the chamber opening by a bulldozer. The bulldozer operator by a radio control causes the platen to move forward, compacting the first load to about one-half the original volume of the loose material. When the ram pressure reaches a predetermined pressure, the platen is automatically retracted. The operation is repeated until a predetermined weight has been received and compacted. Meanwhile a truck has been hitched to the end of the chamber. The operator then actuates controls at said panel. The gate is raised by hydraulic cylinders and the platen moved forward to push the compacted load out of the chamber through the back end of the truck and onto the bed of the truck.
A baling machine comprising an elongated rectangular cross-section, horizontal chamber having an open discharge end and a rearward end, said chamber having a loading aperture in its top, a retractable gate closing off said discharge end, means for retracting said gate, a platen in said chamber, a hydraulic ram fixed to said rearward end of said chamber and to said platen, transport means guiding said platen for reciprocation in said chamber between a retracted position behind said loading aperture to a projected position beyond said discharge end, whereby said platen compacts material deposited in said aperture against said gate when said gate is closed and discharges compacted material out of said chamber through said discharge end when said gate is open, all of said gate being slanted upwardly-rearwardly, said gate comprising the sole discharge end wall of said chamber against which the material compacted by said machine is forced by said platen, said gate when retracted by said means maintaining said compacted material substantially intact.
A baling machine comprising an elongated rectangular cross-section, horizontal chamber having an open discharge end and a rearward end, said chamber having a loading aperture in its top, a retractable gate closing off said discharge end, means for retracting said gate a platen in said chamber, a hydraulic ram fixed to said rearward end of said chamber, and to said platen, transport means guiding said platen for reciprocation in said chamber between a retracted position behind said loading aperture to a projected position beyond said discharge end, whereby said platen compacts material deposited in said aperture against said gate when said gate is closed and discharges compacted material out of said chamber through said discharge end when said gate is open, said platen in side elevation having a vertical stretch at the bottom extending upward approximately half the height of said platen, then an upwardly-forwardly slanted stretch to near the top of said platen and then vertically upward.
