ABSTRACT:
A compacting device adapted to be inserted into a barrel or similar container is provided with a base member having a plurality of upstanding rods secured to the base member in equally spaced relation about the periphery thereof. A support ring surrounds the upper ends of the rods, with each rod being secured to the interior surface of the ring. One or more compacting plates are provided which are adapted to fit within the ring for movement in a direction parallel to the rods. A plurality of spring locking plates equal in number to the rods are secured to the upper surface of the compacting plates for engagement with the rods which are provided with threads along substantially the entire length thereof. Thus, when loose material is placed in the container, and a compacting disc is inserted into the compacting device and pressed downwardly by any suitable press or the like, the material within the container will be compacted. The engagement of the locking plates with the threaded rods prevents the reverse movement of the compacting plate so that upon withdrawal of the press additional material can be added to the container for subsequent compaction.
