Abstract
A trash compactor has a trash compacting head supported by linkage of a type that can be unfolded to extend it and folded to retract it. The linkage consists of first and second sets of links connected to the head in a spaced apart relationship. A pair of parallel, laterally spaced operating members are connected to the linkage and are operable to fold and unfold the linkage to raise the compacting head into its inoperative position or to force it downwardly into an operative position. A reversible drive supported by the structure includes means connecting it to the operating members and is operable to effect their movement in the same direction and to the same extent in both linkage folding and linkage unfolding directions, in the latter direction, even if the resistance to the head is unequal in the direction defined by the connection of the two sets of links with the compacting head. Stabilizing means attached to the head prevent it from tilting in a direction more or less at right angles to the first named direction. The operating members are shown as screws having threaded connections with the linkage and their spacing and their common drive prevents jamming. The trash compact…
