1 Claim.
The present invention relatesto new and useful
improvements in potato sackers, and has for its
primary object to provide, in a manner as herein
after set forth, a device of this character which is
adapted to be expeditiously connected to a con

ture I. An endless screening conveyor I0 is oper
able longitudinally around the frame structure
I, the upper ?ight of said conveyor traveling be
tween the sideboards 9, the lower ?ight of‘said
conveyor passing beneath the platform 5. The
endless conveyor I0 is trained around rollers II

be driven from the digging machine.
Other objects of the invention are to provide a

The conveyor Ill includes endless sprocket
chains I3 which are trained over the sprocket
wheels I2. The endless chains I3 carry sweeps I4,
