Year: 1804

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
EDWARDS, of Bow Street, in the Parish of Saint Paul, Covent Garden, in the
County of Middlesex, Currier and Harness Maker, 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 Fourth day of December,
in the forty-fifth year of His reign, give and grant unto me, the said John
Edwards, my exors, adñiors, and assigns, His special licence that I, the said
John Edwards, my exors, adiñiors, and assigns, during the term of years therein
mentioned, 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 FIRE-PLACES, CALCULATED TO SAVE FUEL, GIVE A MORE
GENERAL HEAT, AND PREVENT CHIMNEYS FROM SMOKING;" in which said Letters
Patent there is contained a proviso obliging me, the said John Edwards, by
an instrument in writing under my hand and seal, to cause a particular de-
scription 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 one calendar month after the date of the said recited Letters Patent.

page_text: Figure 1 represents the front reverberating plate with the pins XX. Figure 4 shews the back reverberating plate with the pins F. G. Figure 2 is the back plate. Figure 3 represents one of the sides, the front of which is towards Figures 1 and 2.. The notches A and
B. receive the pins of the reverberating plates, the front reverberating plate lays upon the line A. C. and extends beyond the perpendicular line D.E. The back reverberating plate lays upon the line B.D. and extends as far as the bottom of the perpendicular
line at D. thereby leaving the aperture C.D. Figure 5 shews the top of the Grate; I is a hole to serve as a flue, and H is a hole for the Boiler. Figure 6 represents the bottom of the Grate, with the bars at J. Figure 7 shews the front of the Grate with
the bars at K. and the place for the door of the oven at L, and the place 4 for another door. N.B. each of the beforementioned parts are entire, and of iron. Figure 8 represents all the pieces in their respective situations. I is the front reverberating
plate (the same as Figure 1) and the back reverberating plate is denoted by the dotted line in the front plate T. The pins of these plates are represented in the notches V. V. of the side plates N.N. M.M. is the back plate the same as Figure 2 and N.N.N.N
are the side plates (the same as represented by Fig. 3.) R.S. is the front of the Grate. Q is the top and W is the back of the fire-place extending from Y to Y of the top plate Figure 5 to Z.Z of the bottom plate Figure 6. Also behind the door R is the Boiler.
S. shews the door of the oven, and at R is another door, the use of this door is to remove cinders or dirt, that may get through the upright bars 3. The cover P is represented in its place, and also the whole of the flue at 0. In this draught the Boi
ler is not represented because its situation is sufficiently obvious from the hole H. Figure 5. and the cover P. Figure 8, between the back M. M. and the back W is a space equal to Y.2. Y.2. Figure 5, through which and the upright bars 3, Figure 8, the heat
passes to the boiler and the oven. The heat is regulated by opening or closing the hole 0. Also the dotted lines surrounding the letter S, shew the opening of this aperture into the oven.
Observations.
two
As each of the parts of this Grate, respectively are entire, and of solid Iron, they retain the heat considerably longer and more intensely than smaller pieces can possibly do. Also the construction of the reverberating plates contributes greatly to
the augmentation of the heat in the room, for the back reverberating plate making an angle with the back of the fire place, the heat which in the usual way is lost in the chimney is by this Invention reflected into the room. A further
advantage of the reverberating plates is seen by inspecting Figure 3. where the back reverberating plate extends from B. to the bottom of the perpendicular line at D, and the front reverberating plate extends from A along the dotted line crossing the perpen
dicular line at C, thereby overhanging the back plate by which construction, the wind blowing down the Chimney is intercepted or cut by the angular meeting of the plates, and the Chimney by this means prevented from smoaking, and the soot or
or blacks by the same means are prevented from flying into the room. By this invention also no rain or hail can possibly fall beyond the reverberating plate in which respect this Invention surpasses that of register stoves for the grate and the hearth
are protected from rain etc: without interrupting the free circulation of air through the Chimney, another considerable benefit results from this invention, the smallness of the aperture through which the smoak escapes increase the draught and
thereby improves the fire, and prevents smoaking etc: etc. In the drawing a Kitchen range has been chosen for a subject but the Invention is applicable and will be applied (with or without the oven) to fire places in general.
