<p>A device for the overturning of polygonal bodies, by a plurality of pivotal elements preferably journalled on shafts located in a common horizontal plane and which elements have edges parallel to the diameters of said shafts and are turned the same direction in synchronization with the body to be overturned initially resting on one of said elements, then during pivoting of said elements, said body by its weight follows the pivoting movement of the edge of the other element against which the body rest while being supported by an edge of the other element in a notch provided between two edges of said elements when they are in an inclined position and finally, when the edge of the other element is turned to a horizontal position, said body rest on said other element after having been overturned an angle which corresponds to the division between two juxtapositioned sides of said body.</p> |
