chains are disposed in vertical planes and are adapted
in the container whereby ?uid will pass onto the ?exible
to move in triangular shaped orbits with the apex of the
rubbing elements as they move through the ?uid, and
triangles directed downwardly. The chains 75, 76 have
horizontally disposed portions contained within the con
tainer 30 extending between sprockets 50, 51 and 52, 53.
The sprockets 54, 55 operate to guide the horizontally dis
posed portions of chains 75, 76 adjacent thereto into the
liquid contained in the container 30. The inclined side
portions of the chains 75, 76 are exposed outside of the
container 30 and receive backing support from the bright
portions 117, 18 of the U-shaped channel members 111, 12.
Positioned above the sprockets 54, 55 are a pair of

lengths "on each element extending from opposite ends
of the container to said lower proximate ends; and stop
means permitting movement of said elements in only one
direction and in opposite directions from one another.
