Year: 1817

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
RAYBOULD, of Goswell Street, in the County of Middlesex, Brass Founder,
send greeting.
WHEREAS His present Majesty King George the Third did, by His
Letters Patent, under the Great Seal of Great Britain, bearing date the
Eleventh day of March now last past, for Himself, Ilis heirs, and successors,
give and graut unto me, the said William Raybould, His especial licence
that I, the said William Raybould, my executors, administrators, and assigns,
or such others as I or they should at any time agree with, and no others,
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 OR IMPROVEMENT APPLICABLE TO FIRE STOVES,
GRATES, AND RANGES OF DIFFERENT DESCRIPTIONS;" in which said Letters Patent
there is contained a proviso, obliging me, the said William Raybould, 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 inrolled in His Majesty's
High Court of Chancery within six calendar months next and immediately
after the date of the said Letters Patent, as in and by the same, reference
being thereto had, will appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
William Raybould, do hereby declare that the nature of my said Invention,
and the manner in which the same is to be performed, is described and

page_text: ascertained by the Drawings hereunto annexed, and the following description
thereof, that is to say:-.
Figure 1, elevation or front view of the stove, with the covings or sliding
back A, A, and B, brought forward to lessen the recess part of the chimney
adapted to a sitting room (when' cooking is not required), with the back
register B close down, the front drop bar C
up.
Figure 2, elevation or front view of the stove; the covings or sliding back
A, A, and B, wound or slided back to give more room for the convenience of
cooking; the register B or part of the sliding back A, A, and B, partly up
to be used as may be required to increase or diminish the draft of air; D, a plate
to slide or drop on to the top part of the stove over the fire, and fit flush with
the plate X, X, for the purpose of heating irons, stew-pans, sauce-pans, or any
other requisite. F and G, the top or cover of the boiler in two parts; the
middle ring F takes out for the purpose of supplying the boiler with water; the
larger or outer ring G takes out with the top F to admit any kind of cylinder,
with cover and drop handle to lift it out or into the boiler for the convenience
of boiling or steaming meat, vegetables, &c.; C, the drop bar of the stove
down; H, a register flue.or chimney; I,-the-oven front, and ventilator; K, the
boiler front, with a cock w in Figures 1 and 2, to dischargo the water from the
boiler; L, door to the fire-place under the oven, to heat it when the fire
in the grate N is not wanted; M, door to the fire-place under the boiler
to heat the boiler when the fire in the grate N is not wanted.
Figure 3, section or view of the stove, with the front (S, S, S, in Figure 2,
taken off); 0, 0, the back plate, with, the centre socket P; Q, the end centre
of the screw N (seen in Figure 6); R, R, side plates to screw the front to
S, S, S, (as seen in Figure 2); T, the inside of the oven; V, the oven shelf;
U, the inside of the boiler; H, HI, inside of the register flew or chimney, to
convey the smoke away behind the perforated plate W in Figure 1, which plate
takes out to place the fuel behind when the fire in the grate N is not wanted,
to prevent accidents that are likely to occur by the usual method of raking
the fire out in front by the hot cinders passing on to the floor; Y,-inclined
plate under H, H, which clears the cinders that fall from behind the
perforated plate W in Figure 1 when clearing the fire out, and slides them
forward under the centre of the grate N in Figure 2; Z, Z, the fire-places
under the oven and boiler as behind L and M, in Figure 2; A, A, two
inclined plates to slide the cinders that fall from the fire-places Z, Z, under
the grate N in Figure 2, for, the convenience of clearing them away with
ease,..and keeping the current of air free from obstruction; b, b, the flues
attached to the oven..and boiler T and U, to convey the smoke. into the

page_text: general chimney; C, C, C, the three rollers or castors, two of them are fixed
behind the front (S, S, S, Figure 1, as shewn at d, d, at the bottom of Figure
2); and one fixed to the back of the oven and boiler; these three rollers or
castors are for the purpose of rolling or sliding the stove in or out of the recess
part of the chimney at convenience, as the intended principle is to avoid setting
it with brick work as usual in other stoves.
Figure 4, plan of Figure 1 with top plate X, X, in Figure 2, shewing the
covings or sliding back (as A, A, and B, in Figure 1,) close up to the back
front of the stove frame (S, S, S, in Figure 2). e, e, rollers or castors to roll
or slide the covings or sliding back A, A, and B, backwards or forwards as
convenience requires; C, C, the rollers or castors (as described in Figure 3);
F and G, the. cover of the boiler (as described in Figure 2); f. f, the two
short cylinders to emit the smoke from the flues b, b, in Figure 3; H, the
register flue or chimney, with the register cover turned up, as described,
behind A, A, and B, in Figure 2.
Figure 5, elevation or view of the back of the covings or sliding back, as
behind A, A, and B, in Figure 2; the register B, part up that forms a part of
the covings or sliding back; h, h, the balance to counterpoise the weight of the
register B; i, i, i, i, the chain fastened to the balance h, h; the other ends
are fastened to the knobs or buttons K, K, on the register B, and pass over
two pulleys or rollers 1, 1, for ease in sliding the register B up or down in a
groove or fillett m, m; e, e, the two castors or rollers, as described in Figure 4.
Figure 6, plan shewing the improved method of moving the covings or sliding
back A, A, and B, backwards or forwards; n, the screw, the end of which,
marked Q, works in the back centre box P; the front centre works in the front
center box p, p, and is screwed thro' the flange r, fastened to the covings or
sliding back A, A, and B, in the centre above the sliding register B, part of
the covings or sliding back. The screw » is turned round by the handle 8, 8, 8,
fitted by a sqare end into a square socket, in the end of the screw in front, as in
the stove frame S, S, S, at the top of Figure 2, and moves the covings or
sliding back A, A, and B, backward or forward at pleasure, with the assistance
of the castors or rollers e, e, on each side of the covings or sliding back at the
bottom, acting on the plate X, X; N, S, a stay bar fastened to the front of the
stove, and back rail o, o, as a support; all the other letters are referred to in
the former Figures.
N.B. The moveable covings or sliding back acting on castors or rollers
in the recess part of the chimney, the flues ascending from the oven and boiler,
and the castors or rollers fixed to the bottom of the grate, constitute the whole
novelty which I claim as my Invention under the said Letters Patent; the

page_text: other parts above introduced or adverted to, being merely for the purpose of
more clear explanation or elucidation, and not as forming any part of my
Invention; and, altho I have described the moving covings, or sliding back,
as acting upon castors or rollers, such castors or rollers may be dispensed with
if desired; and the backward and forward motion may be effected by any other
means than a screw; but I consider the screw preferable. The Invention,
however, which I claim, consists in the backward and forward motion of the
sliding covings or back, by whatever means such motion is effected.
In witness whereof, I, the said William Raybould, have hereunto set my
-hand and seal, the Ninth day of September, in the year of our Lord
One thousand eight hundred and seventeen.
