A long horizontal pipe for a stove soon fills with soot and must be cleaned. The usual method is to beat the pipe after taking it down to be cleaned, but a much better device for the purpose is shown in the sketch.

A scrub brush is procured and cut in two, the parts being hinged to a crosspiece fastened to a long broom handle. The brushes are pressed outward against the inside surfaces of the pipe with a wire and spring, as shown. --Contributed by C. L. Herbert, Chicago, Illinois.
