A METHOD OR METHODS OF REGULATING AND IMPROVING THE DRAUGHT OF CHIMNEYS
Year: 1818

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
PARKER, junior, of Sevenoaks, in the County of Kent, Bricklayer, send
greeting.
WHEREAS His most Excellent Majesty King George the Third, by His
Letters Patent under the Great Seal of the United Kingdom of Great Britain
and Ireland, bearing date at Westminster, the Fifth day of October, in the
fifty-eighth year of His reign, did give and grant unto me, the said Thomas
Parker, my executors, administrators, and assigns, His special licence, full
power, sole privilege and authority, that I, the said Thomas Parker, my executors,
administrators, and assigns, 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 "A METHOD OR
METHODS OF REGULATING AND IMPROVING THE DRAUGHT OF CHIMNEYS;" in which
Letters Patent there is contained a proviso obliging me, the said Thomas
Parker, under my hand and seal, to 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 His Majesty's High Court of Chancery within two calendar months
next and immediately after the date of the said in part recited Letters Patent, as
in and by the same (relation being thereunto had) may more fully and at large
annear

page_text: NOW KNOW YE, that in compliance with the said proviso, 1, the said
Thomas Parker, do declare that my method or methods of regulating and im-
proving the draught of chimneys consists of an apparatus in two separate parts,
to be used either singly or together. The first part of my Invention, which I
call the back part, consists of two sides or parts to form, make, or constitute
the back covings of a fire-place, fixed on the top of the hobs of the grate or
stove at the back part of the same, extending from about the back of the
stove or grate as may be required each way, till they reach the chimney jams;
the said covings are connected at bottom and top, behind the back of the grate
or stove with either a fixed or a-moveable bar,-in order to admit the sweep to
pass freely into the chimney, or for any other purpose. In the said covings
about straight with the under side of the top fixed or moveable bar is a register,
blower, or door, to serve as a ventilator if required, and on the said covings are
cast, made, or placed flutes, astragals, or beads, or both, to receive the second
part of my Invention, which I call the front part, consisting of a register or
registers, blower or blowers, door or doors, shutter or shutters. On the said
covings on both sides I hang or otherwise fix one or more folding or one or
more sliding registers, blowers, doors, or shutters, shutting when closed against
the top and bottom fixed or moveable bar. On the top of the said covings and
to the top fixed or moveable bar I hang or otherwise fix one or more register
or registers, blower or blowers, door or doors, shutter or shutters, extending
from wing to wing of the chimney, intended occasionally to lay or fall from the
top of the covings and bar on which the same are hung against the breast of
the chimney, and from the breast of the chimney to be raised or elevated by
degrees, as may be required; by a screw or otherwise. The second part of my
Invention, which I call the front part, consists of one or more hanging or
folding and of one or more sliding register or registers, blower or blowers,
door or doors, shutter or shutters, constituting side covings, which are to be
hung or otherwise fastened to a slip or standard reaching from the arch of the
breast of the chimney about as low down as the top of the hobs, and as low as
the hearth, if required, behind the stove or other jams, or they may be hung to
iron jams prepared for that purpose; the said register or registers thus hung:
or otherwise fastened will, when shut up square with the front of the jambs, and
intersecting with or meeting or butting or folding against the back part or back
covings, form or make a right angle and a square hob, and will, when moved
forward towards the fire' or centre of the fire-place into the groves or against
the astragals, and in and on the back covings, will contract the opening of the
fire-place and constitute a variety of bevil hobs. The said front register or
registers, being brought forward from their bevel situations nearly flush with the

page_text: stone or other jambs and mantle to which they may be attached, will, by various
degrees, and under a multiplicity of modifications, close or shut up, and thereby
constitute a register or registers, blower or blowers, fire screen or screens, in
the front of the fire-place, grate, or stove, from whatever they may be affixed
or hung to, in front and on each side of the same. In the margin of these
Presents, Figure 1 shews a plan, in which (a) is the back of a chimney; b, b,
the covings above described; c, the fixed or moveable bar; d, d, the registers
in the covings under the top bar, to serve as ventilators when required; e, the
registers or blowers fixed or hung on the covings to close partly or wholly as
required, the aperture through which the flame and smoke passes into the
chimney; f, supposed top of the grate or stove; g, g, the front registers,
shewing the mode in which, by means of the slides (h), they fit into the beads
on the back covings, thereby forming bevel hobs. Figure 2 is a section
shewing the registers or blowers in the front part fastned against the jambs,
and the registers and blowers in the back part opened and fastened back for the
admission of the flame and smoke into the chimney; k, the register on the top
of the covings and on the fixed or moveable bar designed to fall against the
breast of the chimney; 1, the screw to raise and fall the said register.
In witness whereof, I, the said Thomas Parker, have hereunto set my
hand and seal, this Fourth day of December, in the year of our Lord
