ABSTRACT:
A load retraction preventing finger array for a unitary heavy-duty refuse compactor which includes a hopper from which pre-deposited refuse is forcefully thrust by a power-advanced packing blade through an intermediate throat and into a large, normally closed, box-like container which provides a packing chamber in which the load--as it progressively increases in volume upon recurrent operation of the packing blade--is thereby placed under compression; the load retraction preventing finger array embodying a plurality of initially depending, pivoted, dual finger units mounted in a horizontal transverse row extending across the top of such throat and operative in certain positions of engagement with the load of compressed refuse to substantially preclude such load from falling back (by reason of its tendency to expand) through the throat and into the hopper upon retraction of the packing blade.
