Abstract
A box type container used in a press for compacting materials is supported by a floating clamp arrangement that protects the container during compaction and allows significantly higher compaction pressures to be used. The clamps are supported with spherical connections and are pressed to the container with hydraulic cylinders. A container that is fabricated out of square with generous dimensional tolerances is protected as the clamps float to conform to the container being used. All sides and bottom of the box type container are protected with this arrangement.
Claims3
A press for compacting material in a container, said container having a bottom, a plurality of sides, and an open top, said press comprising:
- a pressurized fluid means;
- a vertically movable material compacting means;
- a frame, said frame further allowing the bottom of said container to be supported by the base of said frame;
- means for positioning said container upon the base of said frame relative to the material compacting means;
- a plurality of clamps on the frame sides, each of said clamps comprising a planar member having an inner surface substantially conforming to one side of said container, each of said clamps further being of sufficient rigidity to support one side of said container during compacting;
- a plurality of clamp cylinders operated by said pressurized fluid means, each of said clamp cylinders further having a cylinder rod;
- means for mounting each of said clamp cylinders to said press frame;
- and
- means for pivotally connecting a plurality of said cylinder rods to each of said clamps, allowing said clamps to be pressed against and conform to the sides of said container;
- whereby the container is supported during compacting by the material compacting means by a combination of support by the base of said frame, and the inner surfaces of said clamps.
