Description BACKGROUND OF THE INVENTION
This invention relates generally to compacting presses and specifically
to compacting presses for compacting empty 55 gallon steel drums
or other containers to facilitate the recycle use of the containers'
structural material. Prior art compacting presses have utilized
dedicated tooling, limiting to only one size the container to be
compacted, still others have utilized uniaxial compression to reduce
volume in three dimensional reduction, thus requiring a mold having
an inner cavity having a press fit with the compressed slug and
requiring a means of removing the press fit slug from the mold cavity.

DETAILED DESCRIPTION OF THE DRAWINGS
The preferred embodiment illustrated is not intended to be exhaustive
or to limit the invention to the precise form disclosed. It is chosen
and described to best explain the principles of the invention and
its application and practical use to thereby enable others skilled
in the art to use the invention.
The drum crusher 1 depicted in the drawings includes an I-Beam
frame 6 connecting between a frame bed 8 and an I-beam cross top
frame structure 10. A ram press 12 is guided by rollers 14 shown
in hidden lines, and a sliding fit 15. The ram press 12 is movable
along a centrally located axis, which is parallel with an axis of
the empty 55 gallon steel drum 16. Press 12 is activated by remotely
controlled hydraulic cylinders 18 attached to frame 6 by cylinder
arms 20. The ram press has an air escape hole 22 to relieve any
pressure buildup in the container during crushing. Cutaways 24 in
the press 12 allow the press ram to move past container locating
bars 26 as shown in FIGS. 1 and 3. An air escape hole 28 in frame
bed 8 relieves any pressure buildup in the container during crushing
and minimizes exposure of personnel to possible hazardous conditions.
A safety shield 30 shown in partial broken view in FIG. 1 minimizes
exposure of personnel to possible hazardous conditions. A space
32 is provided between container locating bars 26 and frame bed
8 to allow for manual, mechanical, or, should the drum crusher be
placed in the horizontal position, gravity removal of the compacted
slug 34 upon release of ram press 12.
The drum crusher may be used vertically, horizontally FIGS. 4 and
5 or at an angle. In the latter two cases, drums may be loaded gravitationally
and may rest on the locating bars 26. Bars 26 may be adjustable
or replaceable to fit specific containers, provided matching grooves
or recesses 24 are provided in the head of press 12. When the crusher
is vertically mounted or is mounted at a slight angle to vertical,
the pushing of one drum 16 into the crusher pushes a compacted slug
34 out.
Starting with the locating of an empty 55 gallon steel drum 16
or other container, on the frame bed 8 and the centering of the
container against locating bars 26 and following the closure of
the safety shield 30 the press ram will crush or compact the container
by the remote actuation of the hydraulic cylinders 18. The empty
55 gallon steel drum 16 is crushed into a compacted slug 34 to facilitate
the recycling of the slug material. Air escape holes 22 and 28 have
been provided to prevent pressure buildup during the crushing operation.
The compacted slug can be removed manually or mechanically. Should
the drum crusher be placed in the horizontal position as in FIGS.
4 and 5 the compacted slug 34 will fall by the action of gravity
out through the space 32 upon the beginning of the retraction of
the ram press 12. At the end of the retraction of the ram press,
the safety shield is opened, and the drum crusher is ready for another
container.
While the invention has been described with reference to specific
embodiments, modifications and variations of the invention may be
constructed without departing from the scope of the invention, which
is defined in the following claims. |
