The Mechanical Handling and Storing of Material

I I 2 THE MECHANICAL HANDLING OF MATERLAL position to receive it, when the same process repeats itself again and again, the progress of the object being indicated by e1, e2, e3. In reality the horizontal movement of the trough is only about 1 in., and the vertical between the dotted and the full lines only ~ in. If the trough is full the material moves, as it were, in a solid mass. There is neither friction between the particles of material nor between the trough and the product, as it is a hopping and not a sliding motion which propels the material.
