Abstract: THE APPARATUS COMPRISES A PLURALITY OF WEDGES HAVING SURFACE DELIMITING, AT LEAST IN PART, A CLOSED SPACE IN WHICH SOME MATERIAL IS PLACED TO BE COMPRESSED. THE WEDGES ARE CONTIGUOUS WITH EACH OTHER ALONG CONTACT FACES, AND ARE ABLE TO MOVE RELATIVE TO EACH OTHER BY SLIDING OF THESE CONTACT FACES ON EACH OTHER, TO REDUCE THE VOLUME OF THE CLOSED SPACE. THE WEDGES MUTUALLY SUPPORT EACH OTHER ALONG THESE CONTACE FACES. THE CONTACT FACES OF EACH WEDGE DIVERGE TOWARDS THE EXTERIOR OF THE APPARATUS BY A DISTANCE SUFFICIENTLY LARGE SO THAT THE EXTERIOR

PORTIONS OF THESE WEDGES WHICH ARE NOT MUTUALLY SUPPORTED HAVE DIMENSIONS SUFFICIENT TO WITHSTAND THE STRESSES APPLIED DURING OPERATION.
