2. A material loading machine comprising a support,
the plate-like main portions 34 of the bucket members
will rotate in the manner illustrated in FIGURE 6‘ as the
bucket members move around the lower end of the con
veyor, the bottom loops 60 of the guide channels being
relatively narrow and comprising arcuately curved bottom
portions 61 which merge with the relatively straight top
portions 62 of the channels at a relatively sharp angle
63, shown in FIGURE 6‘. The rollers 54 are thus guided
so that the plate-like main portions 34 of the bucket
members ?rst assume horizontal positions as they move
from the lower portion to the upper portion of the con
veyor at the loading end thereof, the portions 34 gradual
ly rotating from horizontal positions to upwardly ex
tending positions until they reach positions wherein the
rollers 54 engage in the straight top portions 62 of the
guide channels, wherein the bucket members are posi
tioned properly for retaining the material gathered by the
bucket members for movement upwardly towards the top
or discharge end of the conveyor.
It will be seen from FIGURE 6 that the guide chan
