Appeal No. 95-3566
Application No. 07/950,802
the present application, stands withdrawn from consideration
as being non-elected. Claim 1 is illustrative:
1. A transportable oil skimmer comprising:
a) a frame including a motor support section near one
end of the frame, the one end being the top end of the frame
when the skimmer is in use, the frame including a depending
stabilizer adapted to extend into a volume of liquid when the
skimmer is in use;
b) a motor carried by the support section and
including an output shaft;
c) a head pulley drivingly connected to the shaft;
d) an endless belt in drivingly supported engagement
with the head pulley;
e) a tail pulley supported by the belt and adapted to
be immersed in such liquid volume when the skimmer is in use;
and
f) restraining means operatively interposed between
the stabilizer and the tail pulley to limit axial and radial
movement when the skimmer is being transported and to allow
when in use floating movement over a range of movement free of
engagement between the tail pulley and the restraining means
while allowing self alignment of the belt and tail pulley and
sufficient vertical motion when the skimmer is in use to
assure that belt tension is provided substantially only by the
weight of the belt and the pulley.
