after a certain amount of refuse has been deposited that a compaction stroke will occur cooperating with the finger 160 is a permanent magnet 163 fixedly mounted on the equipment shelf 88 the attraction of the finger 160 to the magnet 163 as the door 114 assumes it closed position limits unwanted oscillation or swinging of the door as was mentioned in the introductory portion of the specification the refuse compactor of the present invention is especially designed for use in fast food restaurants and would typically be placed near the exit door where patrons would be expected to deposit their refuse from a serving tray and then place that serving tray atop the cover 108 of the compactor which serves as a storage rack after a preprogrammed number of opening and closing cycles of the refuse deposit door 114 the microprocessor will cause the electric motor and hydraulic pump to be actuated to thereby cycle the compaction plate causing it to move between its elevated position downward to compress the deposited refuse into the container 144 referring to fig5 and 6 as the compaction plate assembly 48 is driven downward from its uppermost position the engagement between the cam follower roller 64 and the arcuate segment 84 and the concave caming surface 87 of the cam plate 72 causes the cam plate 72 to be momentarily hooked and held as the compaction plate assembly begins its downward movement through linkage 68 the movable segment 54 of the compaction plate assembly will be caused to rotate about hinge pin 56 causing it to push down on any trash that may be present until an over center latching action takes place wherein the bottom surfaces of.
