over said bin extending compaction chamber portion
adapted to move from a retracted position through said
cycle has terminated the top operator can again press
the start button to the switch 124 to effect another cycle
of the machine, and, it is obvious that as soon as the bag
and contents are ejected off the chute 20 that the bottom
operator again places a bag 21 on the chute so that the
bing extending compaction chamber portion and through
said chute so as to move the material downwardly out
machine is substantially and continually in operation with 10 of said bin extending compaction chamber portion and
out any loss of time.
In the double unit machine shown there are two top
operators loading on either side of the platform 12 and
two bottom operators receiving the loaded bags at the
bottom of the machine so that tons of loose bulky mate 15
rial can be accurately and uniformly packed and shaped
in a very short time.
In the event that the latter operator is not ready
for delivery he may press the manual interrupt switch 128
stopping the machine anywhere in the cycle and since
the lights 137 and 138 are disposed in view of the top
and bottom operators respectively both operators know

automatically rapidly operating said hopper, side walls,
and said end, and top plates sequentially so that loose
bulky material in said bin is ?rst moved sidewardly with
even sideward compaction, then moved endwardly with
even endwise compaction, and then downwardly with even
topwise compaction so that the material is homogeneous
ly compacted and shaped and sized as desired for the
packaging medium prior to delivery thereto thereby pro
viding a substantially universally evenly compacted ma

and shape.
