page_text: MACNAUGHTAN'S SPECIFICATION.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
MACNAUGHTAN, of Great Queen Street, Lincoln's Inn Fields, in the County
of Middlesex, Ironmonger, send greeting.
WHEREAS His most Excellent Majesty King George the Third did, by His
Letters Patent under the Great Seal of the United Kingdom of Great Britain
and Ireland, bearing date at Westminster, the Twenty-seventh day of Sep-
tember, in the forty-fifth year of His reign, give and grant unto me, the said
James Macnaughtan, my executors, administrators, and assigns, His especial
licence that I, the said James Macnaughtan, my executors, administrators, and
assigns, during the term of years therein mentioned, should and lawfully might
use, exercise, and vend, within England, Wales, and the Town of Berwick
upon Tweed, my Invention of "A STOVE OR GRATE AND RANGE UPON A NEW CON-
STRUCTION, BY WHICH ROOMS WILL BE MUCH MORE EFFECTUALLY WARMED THAN THEY
NOW ARE, AND THE CHIMNIES PREVENTED FROM SMOAKING;" in which said Letters
Patent there is contained a proviso obliging me, the said James Macnaughtan,
by an instrument in writing under my hand and seal, to cause a particular
description of the nature of niy said Invention, and in what manner the same
is to be performed, to be inrolled in His Majesty's High Court of Chancery
within one calendar month after the date of the said recited Letters Patent, as
in and by the same, relation being thereunto had, may more fully and at large
appear.

page_text: NOW KNOW YE, that I, the said James Macnanghtan, in compliance with
the said proviso, do hereby declare that my said Invention is described in the
Drawing hereunto annexed, and the following description :--
A, A, A, A, the front of the stove; B, B, a sliding frame or regulater, being an
oblong or other framed hollow vessel or figure, open at the back, and made to fit
the opening of the stove or chimney, the bottom of which is made of cast iron or
other proper material capable of bearing heat, and the sides and top of wrought iron
or other proper material, which regulator is made to slide or move backwards on
rollers or on bars, or on both, or in any other convenient way. into a recess
made in the back of the chimney to receive it, see B, C, Fig. 2;.but when the
chimney is not of thickness, enough to admit.of such recess, the stove may be
brought sufficiently forward into the room to permit the said recess to be made, or
the said sliding frame or regulator may be hung with or on weights and pullies
so as to move in a perpendicular direction, instead of on a horizontal one, the
chimney being previously made to receive it; and the regulator may also be left
open at the top or sides or otherwise, and for the more easy ascending the
chimney, the front of the regulator may have hinges placed either in the front
or the sides thereof, if thought necessary. C, an aperture in the sliding regu-
lator to receive a key or other fit instrument for the purpose of moving the
regulator backwards and forwards, in order to increase or decrease the heat in
the room; D, D, D, D, the descending flues, made about four inches by six
incles, down or through which the heat and smoke descends and passes along
into and up E, E, E, E, the ascending flucs, which are also made about four
inches by six inches, over the top or sides of the stove into the chimney. The
ascending flues are lined with brickwork or any other materials that will receive
and retain the heat, or they may be made, if thought necessary, without such
lining, according to circumstances. F, F, the edge of the partitions which
divides the descending and ascending flues, which are made of cast iron or any
other fit material; G, G, the brickwork or lining placed internally. Fig. 2,
a side view or section of Fig. 1. A, A, the outside cheek; B, the slide or
regulator; C, the recess, made to receive the regulator; D, D, shew one side
of the sliding bars, &c., another of which is placed on the other side of the stove,
on which the sliding regulator moves backward and forward, as required.
The dotted line E shows the bottom of the flues. F, the front bars; G, the
bottom bars. I apply the regulator also to kitchen and other ranges for the
purpose of conducting the heat or fire round the boilers, ovens, or hot plates,
by placing two bars, one on each hob or nearly on the hobs, rounded or other-
wise on the edges, with corresponding notches made in the regulator that it may
slide easily backwards and forwards on such bars, and in some instances I apply

page_text: a cast iron or wrought iron plate, which, with hinges or pivots or otherwise, is
fixed or fastened and made to fall forwards over the fire from a recess made in
the back of the stove or chimney, which will also have a tendency to force the
smoke and heat in the like direction. Fig. 3, the top of the stove and hobs.
A, A, sliding plates, which pass under the hobs at openings C, C, or may be
made to pass over the hobs, as at B, B, after the manner of a winding range,
or on grooves or slides, or otherwise; a single plate may also be made to pass
in the same direction into a recess made in either side of the chimney, as D.
Fig. 4 is a perspective section of the hobs and flues, preserving the principle.
I vary the mode of construction according to local circumstances; but I con-
ceive the Drawings hereunto annexed and the above description to be fully
adequate to enable every intelligent workman to carry my said Invention into
complete effect.
In witness whereof, I, the said James Macnaughtan, have hereunto set
my hand and seal, this Twenty-sixth day of October, in the year of our
Lord One thousand eight hundred and five
