page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, GEORGE
TAYLOR, of No. 2, Bartholomew Place, Kentish Town, Gentleman, send
greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
5. Royal Letters Patent under the Great Seal of the United Kingdom of
Great Britain and Ireland, bearing date at Westminster, the Thirteenth
day of November, One thousand eight hundred and forty-seven, in the
eleventh year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said George Taylor, my exors, admors, and
assigns, Her especial licence, full power, sole privilege and authority, that I,
the said George Taylor, my exors, admiñors, and assigns, and such others as I,
the said George Taylor, 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, exer-
cise, and vend, within England, Wales, and the Town of Berwick-upon-Tweed,
my Invention of "CERTAIN IMPROVEMENTS IN MACHINERY OR APPARATUS FOR
SWEEPING AND CLEANSING CHIMNEYS, FUNNELS, FLUES, DRAINS, AND OTHER PLACES;"
in which said Letters Patent is contained a proviso, that I, the said George
Taylor, should cause a particular description of the nature of my said In-
vention, and in what manner the same is to be performed, by an instrument

page_text: 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 5
George Taylor, do hereby declare that the nature of my said Invention,
and the manner in which the same is to be performed, are fully described
and ascertained in and by the following statement thereof, reference being
had to the Drawings hereunto annexed, and to the figures and letters marked
thomon that is to co
Figure 1 shews a plan of brush apparatus or machinery combined and con-
structed according to my Invention. Figure 2 is a vertical section of the
same; and Figures 3 and 4 shew some of the parts separately. a, a, shews
the upper part or head of brush machinery, b, b, being four brushes fixed' on
inflexible arms c, c. On these arms are fixed or formed portions of spheres
d, d, which turn in spherical sockets e, e; hence the arms can be moved up and
down freely, there being slits or slots formed in the spherical sockets through
which the inflexible arms c, c, pass. f.f, are forked springs fixed within the
head of the machine, and their other ends come against the plain surface of the
arms c, by which those arms are at all times pressed with a tendency to.
assume the horizontal position, and yet the springs allow of the arms departing
from such horizontal position, simply offering elastic resistance to their moving
out of the horizontal position; hence, although the arms c, c, are inflexible,
they move up and down elastically by the springs. g is the rod to which the
head a, a, is fixed. I would state that the springs may be varied, and the
construction of the spherical parts of the arms c, c, may also be varied, and such
the case in respect to the socket. Figures 5, 6, 7, 8, 9, and 10, shew variar
tions in the construction of these parts, the springs f, f, not being forked as in
the previous figures, but simply press by a flat surface f¹ fixed at the end of the
springs f, and the end of the armis c are differently formed, but they in substance
act as before described. In Figures 5, 6, 7, 8, the slits or openings of the sockets
simply allow of a movement up and down to the arms c, c; but in Figures 9
and 10 there being cross cuts or openings in the sockets, the arms can move
laterally, as well as up and down, or the cuts in the sockets may be made
diagonally, but in each case the springs tend at all times to keep the arms

page_text: horizontal and radial. The peculiarity of this part of my Invention consists
in the use of the portions of spheres at the ends of the arms carrying the
brushes together with springs, which are so arranged as to offer an élastic
resistance to the arms moving from a determined or radial position. Figure
11 shews a section, and Figure 12 a front view of another arrangement,
wherein the arin c, in place of having a portion of a sphere, has a cylinder, or
it might be portions of cones in suitable sockets as shewn, in place of the
spherical ends before described. In this arrangement a flat or plain portion
is formed to receive the pressure of a spring f, by which arrangement the arm
is retained in a horizontal and radial position, and yet by the elasticity of the
spring fit may depart therefrom and will return thereto when free to do so.
Figure 11 shows a section, and Figure 12* front and back views of a similar.
arrangement to the one just described, the only difference being that the cylin-
drical portion c* is placed on the outside of the plate or tube, and it has a
projecting portion f* suitably formed to be acted upon by the spring f. Figure
13 shews a vertical section of part of another apparatus, and Figure 14, a front
view thereof. In this case the spring presses against a lever plate f¹, with
a tendency to force it outwards. c is an arm for carrying a brush which is
attached by an axis c' to the bearings a¹ of the apparatus a, and there are
friction rollers at the end of the arm c, against which the plate f¹ presses; by
which means the tendency is to retain the arm horizontal and radial, but by
the elasticity of the spring the arm c may move up and down as in the former.
cases. In Figures 1 and 2 the apparatus is arranged for four arms c, but this
may be varied whether the arms are arranged and acted on by the means
shewn and described in respect to Figures 1, 2, 3, and 4, or Figures 5, 6, 7,
8, 9, 10, 11, 11, 12, 12*, 18, and 14, the latter Figures only shewn in each
case the arrangement suitable for one inflexible arm c. Another part of the
Invention consists of the mode of mounting the spherical roller h at the top of
the apparatus, as shewn in Figure 1, which consists in applying an elastic
surface of cork i, or it may be india-rubber, prepared or otherwise, so as to
give play and elasticity to the stem j, as shewn.
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 shewn so long as the peculiar character of
either part of my Invention be retained; but what I claim is, first, the
mounting brushes on inflexible arms c, having portions of spheres thereto
combined with the use of the springs, as described in respect to Figures 1 to
10 inclusive.
