page_text: TEAGLE'S SPECIFICATION.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ROBERT
TEAGLE, of Hammersmith, in the County of Middlesex, Plasterer, send'
greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria,-by Her.
Royal Letters Patent under the Great Seal of the United Kingdom of Great
Britain and Ireland, bearing date at Westminster, the Fifth day of November,
in the tenth year of Her reign, did for Herself, Her heirs and successors,
give and grant unto me, the said Robert Teagle, my exors, admors, and
assigns, Her especial licence, full power, sole privilege and authority, that I,
the said Robert Teagle, my exors, admňors, and assigns, or such others as I, the
said Robert Teagle, 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 CHIMNEY POTS AND IN APPARATUS FOR CLEANSING
CHIMNEYS;" in which said Letters Patent is contained a proviso, that I, the
said Robert Teagle, should cause a particular description of the nature of my
said Invention, and in what manner the same is to be performed, by an instru-
ment in writing under my hand and seal, to be inrolled in Her 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
Robert Teagle, do hereby declare that the nature of my Invention, and the

page_text: manner in which the same is to be performed, are fully described and ascer-
tained in and by the following statement thereof, reference being had to the
Drawings hereunto annexed, and to the figures and letters marked thereon,
that is to say:-
My Invention consists, first, of improvements in chimney pots; and, secondly,
my Invention consists of improvements in apparatus for cleansing chimneys.
And in order that my Invention may be most fully understood and readily
carried into effect, I will proceed to describe the means pursued by me.
The chimney pots constructed according to my Invention are of two kinds,
one for being placed just over the fire-place within the chimney, and the other
at the upper part of the chimney; but each arrangement or construction of
pot consists of several compartments or parts, branching or opening into each
other, by which important results in obtaining drafts in chimneys and flues will
be obtained. Figure 1 shows a section, and Figure 2 a plan, of a chimney pot
according to my Invention, to be placed at the lower part of a chimney, and
just above the fire-place or stove. This pot is to be made of clay or other
suitable material; and it consists of the lower part or division a, which
branches off at c, d, and then comes together into one division or compart-
ment at e, which corresponds in size with the chimney above. I would state
that, in place of having only two branches c and d, three or more may be
used where the space will allow, and at the same time permit each branch to
be large enough for the passage of an expanding or other brush of such a
diameter as 'will sweep or cleanse the chimney above. Figure 3 shows a section,
and Figure 4 a plan, of another pot of the same kind as that at Figures 1 and
2, simply differing in the branches c and 'd, being curved in place of being
angular. The effect of using chimney pots with several branches in a chimney
just above the fire-place, will be to prevent, or generally to prevent down-
ward currents, and a better, upward draft will result. Figure 5 is a section,
Figure 6 is an end view, and Figure 7 a plan, of a chimney pot for the upper
part of a chimney, such chimney pot consisting of the enlarged chamber
or division f on the part g; this division or compartment f opens into the
narrower part h, which is surrounded by the part i, and has several fixed vanes
forming channels, up which the outer air passes into the interior of the head
of the pot at j, j, and thence out at the top at k; and I prefer that there
should be a hood or cover at top, as is shown. By this arrangement of large
chamber f, having the lower part 9 opening into it, and then having the pas-
sage or branch h, together with several branches or entrances into it as shown,
there will be great benefit derived in obtaining a draft up a chimney.

page_text: I will now describe the second part of my Invention. Figure 8 shows a
plan, and Figure 9 a section, of a brush apparatus for cleansing chimneys.
Figure 10 shows a plan, and Figure 11 a section, of another brush apparatus,
in which the guide roller is carried by a central spring bar or rod q',
instead of being attached to the brushes. m, n, o, p, are four brushes, each
mounted on the spring stem q, q, q, and the tendency is, that the brushes
should be in an expanded state when not confined or held together as the
parts require to be when being passed up a chimney. The brushes have one or
more guiding rollers or pulleys r, as shewn. s is a cord which, passing over
a pulley t on the brush m, is made fast to the brush n; and v is a branch
cord (from the cord s), which passing over the pulley u on the brush o, is
made fast to the brush p. Hence by drawing on the cords, the brushes will
be brought together, and by fastening the cords, the parts m, n, o, p, will be
held together till the brush apparatus has been raised to its highest position,
when it will be permitted to expand.
Having thus described the nature of my Invention, and the manner in
which the same is to be performed, I would have it understood that I do not
confine myself to the details so long as the peculiar character of either part
of the Invention be retained; but what I claim is, first, the manufacture of
chimney pots as herein described; and, secondly, I claim the manufacture of
brush apparatus for cleansing chimneys, as herein described.
In witness whereof, I, the said Robert Teagle, have hereunto set my
hand and seal, this Fourth day of May, in the year of our Lord
One thousand eight hundred and forty-seven.
