This invention relates generally to a brush
holder, but is directed primarily to a means for
attachment to a scrubbing brush and whereby
the latter may be manipulated without the neces
sity of getting down on one’s knees in so doing.
One of the objects of this invention is to so
construct an attachment for a scrubbing brush
that it will be adjustable to accommodate the
wide range of sizes and shapes of those brushes
