Abstract
A trash compactor has a compacting head supported by two sets of links, each set having a pair of links pivotally interconnected by a member common to both pairs and spacing the two sets of links apart. Corresponding ends of the links are pivotally connected to the head and means connect the other ends of the links to the compactor in a manner enabling the linkage to be unfolded to extend the head into a compacting position or retracted therefrom. Vertical screws, rotated by a reversible drive are threaded through the pivot member to effect such folding and unfolding of the linkage. The ends of the pivot member are within vertical guides and the linkage includes stabilizing links connected to the head.
