Abstract
The cage of a reducing machine is positioned within the machine housing below the rotor. One end of the cage is pivoted with respect to the machine housing, while the other end is suspended from chains which pass over sprockets so that when the sprockets are rotated the cage is either elevated or permitted to descend. Should the cage fail to descend under its own weight, a downwardly directed force is applied to it by pintle-type gears which mesh with gear segments on the cage. The rotation of the gears and the movement of the chains are synchronized.
