Abstract: A CONVEYING ARRANGEMENT WHEREIN AN ENDLESS BELT HAS A WORKING RUN THAT TRAVELS IN AN INCLINED CHUTE HAVING A TOP WALL AND A SUBSTANTIALLY PARALLEL BOTTOM WALL ATTACHED THERETO BY SIDE WALLS WITH THE BOTTOM WALL BEING DISCONTINUOUS AND INTERRUPTED BY CUT-OUT PORTIONS, THE BELT HAVING A BEARING FACE SLIDABLY DISPOSED ON THE BOTTOM WALL AND CLOSING OFF THE CUT-OUT PORTIONS SO AS TO COMPLEMENT THE TOP AND SIDE WALLS IN ACHIEVING A CONDUIT EFFECT IN WHICH THE WORKING RUN TRAVELS. THE BELT HAS A WORKING FACE PROVIDED ON ITS OPPOSITE SIDES WITH UPSTANDING ENDLESS FLANGES AND, INTERMEDIATE THE SIDE FLANGES, WITH A PATTERN OF SPACED AND STAGGERED PROJECTING NUMBS THAT EXTEND SUBSTANTIALLY TO THE UNDERSURFACE OF THE TOP WALL FOR MOVING SUBSTANCES THROUGH THE CHUTE WITH THE BELT BEING DRIVEN THROUGH THE CHUTE AT A LINEAR SPEED GREATER THAN THE FALL BACK SPEED OF A CONVEYED SUBSTANCE ON THE WORKING FACE OF THE BELT.

Abstract: A conveying arrangement wherein an endless belt has a working run that travels in an inclined chute having a top wall and a substantially parallel bottom wall attached thereto by sidewalls with the bottom wall being discontinuous and interrupted by cutout portions, the belt having a bearing face slidably disposed on the bottom wall and closing off the cutout portions so as to complement the top and sidewalls in achieving a conduit effect in which the working run travels. The belt has a working face provided on its opposite sides with upstanding endless flanges and, intermediate the side flanges, with a pattern of spaced and staggered projecting nubs that extend substantially to the undersurface of the top wall for moving substances through the chute with the belt being driven through the chute at a linear speed greater than the fall back speed of a conveyed substance on the working face of the belt.

Abstract: A means and method of elevating liquids and semiliquids employing a conveying belt having nubs projecting from the working face, the nubs are not oriented in transverse alignment but are mismatched in a particular manner depending upon the materials being conveyed; the belt may have a confined area in which to travel in the form of a rectangular tube, thereby allowing virtually no space for roll back of the materials.
