My invention relates to a package delivery
chute and has for one of its objects to produce
a delivery chute which will deliver with certainty
and without damage the lower or first package
from a line or stream of packages that are sup
plied more or less continuously to its upper end.
At Warehouses, factories, stations and other
places where trucks or cars are loaded with mer~

tilting extension.

In the drawing, Ill indicates a chute, which
may be one of a multiple series arranged either
horizontally or vertically, downwhich packages
