page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, SAMUEL
STOCKER, of the City of Bristol, Machinist, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Letters Patent under the Great Seal of Great Britain, bearing date at West-
minster, the Twenty-first day of August, in the second year of Her reign, did,
for Herself, Her heirs and successors, give and grant unto me, the said Samuel
Stocker, Her especial licence, full power, sole privilege and authority, that I,
the said Samuel Stocker, my exors, admors, and assigns, or such others as I,
the said Samuel Stocker, my exors, admors, or assigns, should at any time
agree with, and no others, from time to time and at all times during the term
of years therein expressed, should and lawfully might make, use, exercise, and
vend, within England, Wales, and the Town of Berwick-upon-Tweed, my.
Invention of "IMPROVEMENTS IN CHIMNEYS FOR DWELLING HOUSES, AND APPARATUS
FOR SCRAPING, SWEEPING, OR CLEANING CHIMNEYS, AND IN THE 'MANUFACTURE OF
SUCH APPARATUS AND OF THE MATERIALS OF WHICH SUCH CHIMNEYS ARE FORMED;"
in which said Letters Patent is contained a proviso' that I, the said Samuel
Stocker, shall cause a particular description of the nature of my said Invention,
and in what manner the same is to be performed, to be inrolled in Her

page_text: said Majesty's High Court of Chancery within six calendar months next and
immediately after the date of the said in part recited Letters Patent, as in
and by the same, reference being thereunto had, will more fully and at large
appear..
NOW KNOW YE, that in compliance with the said proviso, I, the said
Samuel Stocker, do hereby declare that the nature of my said Invention, and
the manner in which the same is to be performed, are particularly described
and ascertained in and by the following statement thereof, reference being
had to the Drawing hereunto annexed, and to the figures and letters marked
thereon (that is to say):-
The first part of my Invention relates to a mode of constructing chimneys
for dwelling houses, by which a chimney may be produced much better
adapted for being cleaned by mechanical means than the ordinary brick
chimneys now in use, and such chimneys will occupy comparatively little
space..
The second part of my Invention relates to a mechanical apparatus for
scraping, sweeping, or cleaning chimneys, whereby I am enabled to dispense
with the use of climbing boys, the apparatus being of so simple a nature that
the act of cleaning the chimney may be performed by a servant without the
slightest difficulty.
DESCRIPTION OF THE DRAWING.
Figure 1 shews a view in elevation partly in section of a chimney built
according to my Invention, a being the brickwork, and b, b, b, are a series of
earthenware tubes, which may be similar to the red chimney pots now in use,
or they may be of stone, pottery, or other such clay; and the tubes are so con-
structed that the lower part of each is made sufficiently large to pass on to the
extent of two or three inches over the top of the preceding tube as it is inserted
in the brickwork, as shown at c. The wall or brickwork shewn is what is called
by builders "first-class work," that is, two bricks thick, and the tubes are nine
inches diameter, which may, however, be varied according to circumstances. In
building a chimney according to the plan I have shewn, the first tube will be
placed in the centre of the brickwork, as at Figure 4, at or near the top of the
space for the stove, and the brickwork built round it, filling any space that may
be left between the tubes and bricks with mortar or cement. When the
brickwork is completed to nearly the top of the first tube a second tube is to be
placed with the large end over the top of the lower tube, and the brickwork is
to be continued, and mortar or cement applied as before, and so on till the
chimney is carried to the height required. Figure 2 is a plan in section of

page_text: Figure 1, and Figure 3 is one of the tubes shewn separately. It is evident
that square or other shaped tubes may be employed, but those I have shown I
consider the best form.
I will now describe the second part of my Invention, which relates to
improvements in apparatus for scraping, sweeping, or cleaning chimneys.
Figure 4 shews the section of a chimney having my improvements applied
thereto, d being a drum or roller having spindles working in uprights e, shewn
in Figures 1 and 4. f is a chain passing over the drum or roller. When the
apparatus is required for use, the brush is to be attached to the chain by
hooks or otherwise, as shewn, and on being drawn up and down the chimney,
the brush, coming in contact with the sides, will very speedily cleanse it of
soot. (Fig. 5 shews the form of brush which I use in crooked chimneys.
This brush is composed of a series of elastic brushes similar to those used for
cleaning bottles, and by its elasticity will readily adjust itself the bends of
the chimney). The brush may be detached and the chain placed out of the
way on the side of the fireplace. I would observe that although I have
described a brush, it is evident that other articles may be used, such as a
scraper of iron.
Fig. 7 shews another mode of cleaning chimnies, whereby the chain only
is used, which chain is attached to the wheel a. By throwing round this
chain with the hand from below, the lateral chain 6 will come in contact with
the sides of the chimney and remove the soot. And I would remark that
although I have shewn my improved apparatus applied to a chinney formed
according to my first-described improvements, it will be evident that it may
be applied to the ordinary construction of chimneys, as shewn at Fig. 6.
Having thus described the nature of my said improvements, and the
manner of carrying the same into effect, I would have it understood that what
I claim as the Invention secured under the present Letters Patent, is,-
First, the mode of constructing chimneys as above described; and,
Secondly, I claim the mode of arranging apparatus, having a roller or
suitable supports at the top of the chimney for a chain or cord to work on, as
above described, for sweeping, scraping, or cleaning chimneys.
In witness whereof, I, the said Samuel Stocker, have hereunto set my hand
and seal, this Fifteenth day of February, in the year of our Lord
One thousand eight hundred and thirty-nine.
