AN IMPROVED APPARATUS FOR CLEANING CHIMNEYS
Year: 1884

page_text: I, JOHN JARMAN of No 12 Florence Street Birmingham in the County of
Warwick Agent do hereby declare the nature of my Invention for "AN IMPROVED
APPARATUS FOR CLEANING CHIMNEYS" to be as follows:-
The object of my invention is to produce an apparatus which shall be most
flexible in its general parts so as to easily adapt itself to the various turns and
projections of a roughly built chimney or flue and at the same time it possesses
sufficient stiffness in all its parts to bring the apparatus to bear upon all parts of
the chimney or other flue.
The top part or head of the apparatus is screwed or otherwise secured to the
point of the upper stem and has a circular steel or other wire brush at the top and
two projecting arms a little distance under this brush. These arms being made
clastic by the introduction of suitable spiral and flat springs and ends formed for
scraping the sides of the flues. The main body of the apparatus is composed of
four or other number of arms hinged to the top of the upper stem and curved
downwards and fitted on the outer face with steel or other flat wires or fibres to
form a metallic brush-These brushes are kept to their work by suitable springs
bearing against the back of the brush and the upper stem in such a manner that
the range of contraction and expansion is very great and spiral steel brushes may
also project from the sides on arms formed by spiral springs so as to give very
great flexibility to the said side brushes. Where the flues are very large the
brushes may be connected to the upper stem by compensating arms so as to give
them a greater range of adjustment. The portions of the stem next to the upper
portion are connected thereto with screw sockets but also having a strong spiral
spring in the said upper joints which allows the stem to adapt itself to the turns in
the chimney no matter in what direction the turns may be.
The spiral springs introduced into this apparatus not only gives elasticity to the
arms or other surfaces but also allows the circular brushes to revolve to some
extent without danger of breakage and also to easily regain their norinal position
and shape when liberated and thus a similar flexibility to that of a human arm is
imparted to the various parts of the apparatus.

SPECIFICATION.
1, J. JARMAN of N° 12, Florence Street, Birmingham in the County of
Warwick Agent, do hereby declare the nature of the said Invention for
«AN
" IMPROVED APPARATUS FOR CLEANING CHIMNEYS" and in what manner the
same is to be performed to be particularly described and ascertained in and by the
following statement that is to say :-
The object of my invention is to produce an apparatus which shall be most
flexable in its general parts so as to easily adapt itself to the various turns and
projections of a roughly built chimney or flue and at the same time possess
sufficient stiffness in all its parts to bring the apparatus to bear upon all parts of
the chimney or other flue.
The top part or head of the apparatus is screwed or otherwise secured to the
point of the upper stem and has a circular steel or other wire brush at the top and
two projecting arms a little distance under this brush-These arms being made
elastic by the introduction of suitable spiral and flat spring and ends formed for
scraping the sides of the flues.
.!
The main body of the apparatus is composed of four or other number of arms
binged-to-the-top-of-the-upper-stem-and-curved-downwards-and-fitted-on-the-outer-
face with steel or other wires or fibres to form a metallic brush. These brushes
are kept to their work by suitable springs bearing against the back of the brush
and the upper stem in such a manner that the range of contraction and expansion
is very great and spiral steel brushes may also project from the sides on arms
formed by spiral springs so as to give very great flexibility to the said side brushes.
Where the flues are very large the brushes inay be connected to the upper stem by
compensating arms so as to give them a greater range of adjustment. The portions
of the stem next to the upper portion are connected thereto with screw sockets but
also having a strong spiral spring in the said upper joints which allows the stem
to adapt itself to the turns in the chimney no matter in what direction the turns
may be.
The spiral springs introduced into this apparatus not only gives elasticity to the
arms or other surfaces but also allows the circular brushes to revolve to some
extent without danger of breakage and also to easily regain their normal position
and shape when liberated and thus a similar flixibility to that of a human arm is
imparted to the various parts of the apparatus.
In order that my invention may be more clearly understood and better carried
into practice, I have appended hereunto a sheet of drawings showing one of the
commonest forms of my apparatus for general work and from which many other
forms may be made to suit various special conditions which will be met with,
Figure 1 is a side elevation and Figure 2 is a plan of top with leading wheel
removed.
.
Now referring to the drawing A, B and C are three brushes fastened to the head
of the wood, or other stem which finishes with a screw socket E to which the rods
or elevating canes or lengthening bars may be screwed.
F is a socket plate formed into three springs which radiate therefrom curving
downwards behind the back of each brush and fastened thereto by the rivets
or screws To. the bottom of each brush springs K are attached through the
socket M which is free to slide up and down to suit the action of the brushes as
they contract or expand in various parts of the flue pipe chimney or other internal
part to be swept or scraped. The back of the brushes may be made from Metal
wood or other material but the projecting prongs of the brush would generally be
of steel.

page_text: To the upper part F may be screwed a supplemental top in place of the wheel P
or it may be used separately or alone and may be in shape triangular, square,
pyramidal or other shape and being fitted with a suitable guide ball. This is
specially suitable for cleansing the tops or pots of chimneys.
The springs for expanding and contracting the brushes may be greatly varied in
design and kind according to the build of chimney or work required. Scrapers
may also be used either in place of or in conjunction with the brushes.
Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed I declare that what
I claim is
The improved apparatus for cleaning chimneys of a series of brushes, hung to a
stem or centre D by means of contracting and expanding springs for enabling the
brushes or scrapers to adapt themselves to irregularities and variations of such flues
pipes or other parts, and substantially as herein set forth.
