Year: 1830

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES:
CHADLEY, of Gloucester Street, Queen's Square, Surveyor, send greeting.
WHEREAS His present most Excellent Majesty King William the
Fourth, by His Letters Patent under the Great Seal of Great Britain, bearing
date at Westminster, the Thirteenth day of September, in the first year of
His reign, did, for Himself, His heirs and successors, give and grant unto.
me, the said James Chadley, His especial licence that I, the said James
Chadley, my executors, adiñors, and assigns, or such others as I, the said
James Chadley, my executors, 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 "CERTAIN IMPROVEMENTS IN MAKING OR FORMING BRICKS,
TILES, AND CHIMNEY BARS APPLICABLE TO THE BUILDING OR ERECTING THE FLUES:
OF CHIMNEYS;" in which said Letters Patent is contained a proviso, obliging
me, the said James Chadley, by an instrument in writing under my hand and
seal, particularly to describe and ascertain the nature of my said Invention,
and in what manner the same is to be performed, and to cause the same to.
be enrolled in His said Majesty's High Court of Chancery within six calendar.
months next and immediately after the date of the said recited Letters Patent,
as in and by the same, reference being thereunto had, will more fully and at
large appear.

page_text: NOW KNOW YE, that in compliance with the said proviso, 1, the said
James Chadley, do hereby declare the nature of my said Invention to
consist,―
First, in forming bricks intended for chimney flues bevelled on the inside
in such manner as to meet the necessities of the required turns and windings
of the chimney, while the top and bottom sides, being flat and parallel to each
other, the bricks have a firm and steady bearing on each other.
Secondly, in forming tiles of one sort in such manner as to form, when set
one upon the other, a smooth lining for a chimney fluo; and of another sort in
such manner as to form, when laid side by side, the necessary turns for soffittes.
And, thirdly, in forming chimney bars with both a front and back lip to
catch the bottom of the bricks and tiles, whereby I am enabled to do away
with the square projecting breastwork usually occasioned by the ordinary mode
of building on the common bar.
And in further compliance with the said proviso, I, the said James Chadley,
do hereby describe the manner in which my said Invention is to be performed,
reference being had to the Drawings annexed, and to the figures and letters
marked thereon (that is to say):-
DESCRIPTION OF THE DRAWINGS.
On Sheet 1, Figures 2, 4, 6, and 10 represent various forms of bricks, all
with bevelled edges to the inside of the flue, with which I propose to build
chimney flues, and which shapes it appears to me are all that will be required
for any ordinary stack of chimney flues; in these Figures the coloured parts
shew the singlo brick referred to, and the plane lines the bricks which should
be associated with them to form the work, and which are as follows:-A, plan
of brick thick, being the common thickness; B, the same; C is a common
brick or batt used in this course; D, plan of brick 24 thick; E is a brick
similar to A, to be used in a thinner wall; F is a brick similar to B, to be
used in a thinner wall; G is a brick similar to D, to be used in a thinner
wall; H, H, are bricks formed with bevel faces a, a, to conduct the flue right
or left, one being right, and the other left; I, I, are bricks formed with bevil
faces a, a, to conduct the flue in another direction, being right and left; J is a
brick 2 thick, and four of these bricks in one course and two courses will
turn the flue half round; K is a brick alternately used when two flues aro
near each other; L is a brick for a circular flue, being of a parallel thickness
of 2 inches, cach course rising only the height of common bricks; M, M, arc
bricks formed with bevil faces a, a, to a circle of twelve inches diameter, they
are formed right and left. Figure 11 is an elevation of three of my proposed

page_text: tiles for lining chimneys; and Figure 12 is a plan of a flue lined with the
same; Figure 13 is a representation of one of my soffitte tiles; and Figure
14 is a plan of two of the said last-named tiles resting in their places
on the chimney bar; of course these tiles, as the soffitte gathers over,
will be cut to suitable lengths by the workman. N, N, N, shew three
tiles thick, each formed with a rebate for the succeeding one to fit in, as
seen in plan; 0, 0, is plan of tiles to a flue twelve inches diameter; P, P,
shows plan of two soffitte tiles resting on a bar 2 inches wide; they are formed
right and left; Q shews the under side of one tile. Figure 15 is a front eleva-
tion of my said improved chimney bar; and Figures 16 and 17 are sections
of the same; R is the front view of a cast-iron chimney bar four inches wide.
I propose to make bars on the same principle only 2 inches wide; b, b, is an
iron cramp which may be used if thought expedient to tie in the brick jambs.
Sheet 2 represents the mode of introducing all my said improvements into
the various pieces of building to which they are severally applicable, and a
reference to the explanation added to each Figure on the Sheet will sufficiently
instruct the builder how to proceed; and it will be seen that I am sometimes
obliged to use bricks without bevelled edges, as shewn in Figures 1, 3, 5, 7, 8,
and 9, in Sheet 1, but which forms, however, I do not claim as my Invention.
Now whereas I claim as my Invention, first, the bricks with bevelled edges
to the inside of the flue for the purpose of obtaining the turns and windings
aforesaid.
Secondly, the form and position of tiles berein-before described for the
several purposes aforesaid.
And, thirdly, the form of chimney bar with sloping back and elevated front
edge, as aforesaid.
And, such my Invention being to the best of my knowledge and belief
entirely new, and never before used within that part of His said Majesty
United Kingdom of Great Britain and Ireland called England, His said
Dominion of Wales, or Town of Berwick-upon Tweed, I do hereby declare
this to be my Specification of the same, and that I do verily believe this my
said Specification doth comply in all respects fully and without reserve
or disguise with the proviso in the said herein-before in part recited Letters
Patent contained wherefore I do hereby claim to maintain exclusive right
and privilege to my said Invention.
In witness whereof, I, the said James Chadley, have hereunto set my
hand and seal, this Twenty-sixth day of February, in the year of our
Lord One thousand eight hundred and thirty-one.
JAMES (L.S.) CHADLEY.
