Heretofore, joining set being adjacent, the effect being in the use of this system considerable difiito produce a series of inclines, the high rollculty has been encountered by the packers in er of each set serving to prevent the boxes pulling the boxes off side ways owing to the or packages from travelling backwards, the fact that the ends of the. boxes abutted to length of each grade. being sufficiently long- 30 gether, necessitating great effort in sepaer thanthe packages to be handled toperrating the same. mit the same to become separated slightly.

2. A "conveyer table formed of a plurality of setsofrollers revolubly mounted at their ends, the rollersof .eaehsetbeing so mounted that their upper surfaces form an incline with the ;.horizontal, the high roller of each set and the lower roller of each adj oinin set being adj acent, whereby packages are prevented from moving back-- wards.

A conveyer table. formed of aplurality of sets of rollers, the rollers of each set being so mounted that their upper surfaces are slightly inclined to the horizontal, the inclination of each of said setof rollers being'in parallel planes.

4:. A 'conveyer table comprising apluraL ity of rollers revolubly' mounted at their ends, said rollers being so mounted as to form a plurality of inclines extending in thesame direction, the highest roller and the lowest rollerof the adjoining sets being adjacent.
