Claims

1. APPARATUS FOR TRANSPORTING A DEFORMABLE OBJECT HAVING TWO OPPOSITE FACES, SUCH AS A FLEXIBLE-WALLED BAG FILLED WITH FLOWABLE MATERIAL, FROM A FIRST LEVEL TO A SECOND LEVEL, COMPRISING:

MEANS DEFINING AN UNEVEN CARRYING SURFACE MOVABLE THROUGHOUT A TWO-SEGMENT PATH WHEREIN DURING A FIRST SEGMENT THE UNEVEN CARRYING SURFACE IS GENERALLY HORIZONTAL AND UPWARDLY PRESENTED AND A SECOND SEGMENT THE UNEVEN CARRYING SURFACE IS GENERALLY STEEPLY CANTED AND FACES GENERALLY HORIZONTALLY;

MEANS FOR MOVING SAID UNEVEN CARRYING SURFACE THROUGHOUT SAID PATH INCLUDING MEANS FOR CANTING SAID UNEVEN CARRYING SURFACE AT THE JUNCTURE OF SAID FIRST AND SECOND PATH SEGMENTS;

MEANS DEFINING ALTERNATING PROJECTIONS AND RECESSES ON SAID UNEVEN CARRYING SURFACE PROCEEDING TRANSVERSELY THEREOF AND SPACED FROM ONE ANOTHER LONGITUDINALLY THEREOF RESPECTING SAID PATH;

SUCCESSIVE PROJECTIONS AND RECESSES BEING CLOSER TO ONE ANOTHER THAN THE LENGTH OF ONE FACE OF SAID DEFORMABLE OBJECT;

SAID UNEVEN CARRYING SURFACE BEING CONSTRUCTED AND ARRANGED TO RECEIVE SAID DEFORMABLE OBJECT FACEWISE WITHIN THE FIRST SEGMENT OF SAID PATH AND TO DEFORM THE ONE FACE OF SAID DEFORMABLE OBJECT PRESENTED THEREAGAINST INTO SUBSTANTIAL CONFORMANCE WITH A PLURALITY OF SAID PROJECTIONS AND RECESSES UNDER THE FORCE OF THE WEIGHT OF SAID DEFORMABLE OBJECT ON THE UNEVEN CARRYING SURFACE WITHIN SAID PATH FIRST SEGMENT;

MEANS DEFINING A SMOOTH WALL ARRANGED ADJACENT THE SECOND SEGMENT OF SAID PATH AND BEING SUBSTANTIALLY COEXTENSIVE THEREWITH;

SAID SMOOTH WALL BEING CONSTRUCTED AND ARRANGED TO FACE SAID UNEVEN CARRYING SURFACE THROUGHOUT THE SECOND SEGMENT OF THE PATH THEREOF;

MEANS MAINTAINING SAID SMOOTH WALL SO CLOSE TO SAID PATH SECOND SEGMENT AS TO ENGAGE THE OPPOSITE FACE OF SAID DEFORMABLE OBJECT FROM SAID ONE FACE SUFFICIENTLY TO PREVENT SUBSTANTIAL RELATIVE LONGITUDINAL SLIPPAGE BETWEEN THE DEFORMED DEFORMABLE OBJECT ONE FACE AND SAID UNEVEN CARRYING SURFACE DURING SAID PATH SECOND SEGMENT YET ALLOW SLIDING MOVEMENT OF SAID DEFORMABLE OBJECT OPPOSITE FACES ALONG SAID SMOOTH WALL;

MEANS DEFINING A SECOND UNEVEN CARRYING SURFACE MOVABLE THROUGHOUT A SECOND TWO SEGMENT PATH WHEREIN DURING A LOWER FIRST SEGMENT THE SECOND UNEVEN CARRYING SURFACE IS GENERALLY STEEPLY CANTED AND FACES GENERALLY HORIZONTALLY AND AN UPPER SECOND SEGMENT THE SECOND UNEVEN CARRYING SURFACE IS GENERALLY HORIZONTAL AND UPWARDLY PRESENTED;

MEANS FOR MOVING SAID SECOND UNEVEN CARRYING SURFACE THROUGHOUT SAID SECOND PATH INCLUDING MEANS FOR CANTING SAID SECOND UNEVEN CARRYING SURFACE AT THE JUNCTURE OF SAID SECOND PATH FIRST AND SECOND SEGMENTS;

MEANS DEFINING ALTERNATING PROJECTIONS AND RECESSES ON SAID SECOND UNEVEN CARRYING SURFACE PROCEEDING TRANSVERSELY THEREOF AND SPACED FROM ONE ANOTHER LONGITUDINALLY THEREOF RESPECTING SAID SECOND PATH;

SUCCESSIVE PROJECTIONS AND RECESSES BEING CLOSER TO ONE ANOTHER THAN THE LENGTH OF ONE FACE OF SAID DEFORMABLE OBJECT;

SAID SECOND UNEVEN CARRYING SURFACE BEING CONSTRUCTED AND ARRANGED ABOVE AND IN LONGITUDINAL ALIGNMENT WITH THE SECOND SEGMENT OF THE PATH OF THE FIRST-MENTIONED UNEVEN CARRYING SURFACE TO RECEIVE SAID DEFORMABLE OBJECT FACEWISE FROM THE FIRST-MENTIONED UNEVEN SURFACE AT THE LOWER END OF THE FIRST SEGMENT OF THE PATH OF SAID SECOND UNEVEN CARRYING SURFACE AND TO RECEIVE THE FACE OF SAID DEFORMABLE OBJECT PRESENTED THEREAGAINST IN SUBSTANTIAL CONFORMANCE WITH A PLURALITY OF SAID PROJECTIONS AND RECESSES;

MEANS DEFINING A SECOND SMOOTH WALL ARRANGED ADJACENT THE FIRST SEGMENT OF SAID SECOND PATH AND BEING SUBSTANTIALLY COEXTENSIVE THEREWITH;

SAID SECOND SMOOTH WALL BEING CONSTRUCTED AND ARRANGED TO FACE SAID SECOND UNEVEN CARRYING SURFACE THROUGHOUT THE SECOND PATH SECOND UNEVEN CARRYING SURFACE THROUGHOUT THE WALL SO CLOSE TO SAID SECOND PATH FIRST SEGMENT AS TO ENGAGE THE OPPOSITE FACE OF SAID DEFORMABLE OBJECT FROM THE FACE RECEIVED BY SAID SECOND UNEVEN CARRYING SURFACE SUFFICIENTLY TO PRESENT SUBSTANTIAL RELATIVE LONGITUDINAL SLIPPAGE BETWEEN THE DEFORMED FACE OF THE DEFORMABLE OBJECT AND SAID SECOND UNEVEN CARRYING SURFACE DURING SAID SECOND PATH FIRST SEGMENT YET ALLOW SLIDING MOVEMENT OF SAID DEFORMABLE OBJECT OPPOSITE FACE ALONG SAID SECOND SMOOTH WALL;

AND MEANS SUPPORTING SAID FIRST MENTIONED AND SAID SECOND UNEVEN CARRYING SURFACE AND MAINTAINING SAID FIRST MENTIONED UNEVEN CARRYING SURFACE PATH SECOND SEGMENT IN LONGITUDINAL ALIGNMENT WITH THE FIRST SEGMENT OF SAID SECOND PATH;

SAID SUPPORTING AND MAINTAINING MEANS BEING CONSTRUCTED AND ARRANGED TO PROVIDE AT LEAST 180 DEGREES OF RELATIVE ROTATION BETWEEN THE FIRSTMENTIONED UNEVEN CARRYING SURFACE WITH RESPECT TO THE SECOND SEGMENT OF THE PATH THEREOF AND THE SECOND UNEVEN CARRYING SURFACE WITH RESPECT TO THE FIRST SEGMENT OF THE PATH THEREOF.
