Improvements in Brushes for Chimney Sweeping or Flue Cleaning.
WILLIAM LITTLEWOOD,, South Street, New Whittington, hear Chesterfield,
Derbyshire, Blacksmith do hereby declare the nature of this invention to be as
follows:-
:-
This flue cleanser consists of two different sized brushes. The first brush X to
be 14" x 10" or any other convenient size or shape for different sized flues. The
second brush Y about 4 feet above X and about 7" in diameter for the cleansing of
the chimney pot. The brush X is for the purpose of cleansing the flue up as far
as the pot. The larger brush consequently does not pass through the chimney pot,
no damage being caused by an unusual sized brush passing through a considerably
less area of pipe. The two brushes may or may not be connected with a screwed
joint. The lengthening rods to be made of cane with screwed joints as in the
present brushes. The brushes are to be made of whale bone bristles glued into
wooden bosses of convenient size.

Improvements in Brushes for Chimney Sweeping or Flue Cleaning.
WILLIAM LITTLEWOOD South Street New Whittington near Chesterfield
Blacksmith do hereby declare the nature of this invention and in what manner the
same is to be performed, to be particularly described and ascertained in and by the
following statement :—
This flue cleanser consists of two different sized brushes. The larger one A &
the smaller B. It has also two small rollers C at the leading end of the brush.
The larger brush A is 18 inches in diameter or thereabouts to suit different flues.
It is not attached to the brush rods but works loose up and down the rod. In
sweeping the flue or chimney, the brush A falls on to the lug D, cast on the brass
ferrule E, which sustains the brush as it goes up the flue. This large brush A is
for the purpose of sweeping the flue up to the underside of the chimney pot. The
chimney pot is cleansed by means of the smaller brush B about 7 inches in diameter,
the two brushes being led up and along the flue by means of the rollers C. C.
These rollers can revolve round their axle F and together can revolve also round
the axle G, thus changing into any position as may be required as they pass up
and along the flue. The axle G is screwed into the boss of the smaller brush.
Directly under the smaller brush, the rods are connected by brass ferrules &
screwed joints. When the brushes have reached the top of the flue & the larger
brush is immediately beneath the chimney pot, the rods are lowered down the flue.
The larger brush A running loose upon the rods remains stationary in the flue
until the boss of brush B strikes the boss of brush A. The brush A will then be
drawn down along with the rods and brush B. The spring H will support the
larger brush A in the descent, so that the brushes A, B and rollers C. C. are
all together when they reach the chimney bottom, where they will be convenient for
cleaning the chimney back & for removing from the flue as one brush. The
bosses of the brushes A and B can be made of wood or other suitable material of
convenient proportions & the bristles of the brushes of bass broom.

page_text: Having now particularly described and ascertained the nature of my said inven-
tion & in what manner the same is to be performed I declare that what I
claim is :-
1). The adoption of the smaller brush B for the cleansing of the chimney pot.
2). The leading rollers C. C for leading the brushes up and along the flue.
3). The larger brush A being loose upon the rods.
4). The working arrangement of brush A as herein described. .
