AN IMPROVED GRATE OR APPARATUS
Year: 1815

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, CHARLES
COLDRIDGE, of the City of Exeter, 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 Eighteenth day
of July, in the fifty-fifth year of His reign, give and grant unto me, the
said Charles Coldridge, my exors, admors, and assigns, His especial licence,
full power, sole priviledge and authority, that I, the said Charles Coldridge,
my exors, admors, and assigns, should and lawfully might, during the term of
years therein mentioned, make, use, exercise, and vend, within England,
Wales, and the Town of Berwick-upon-Tweed, my Invention of "AN
IMPROVED GRATE OR APPARATUS;" in which said Letters Patent there is con-
tained a proviso that if I, the said Charles Coldridge, shall not particularly
describe and ascertain the nature of my said Invention, and in what manner
the same is to be performed, by an instrument in writing under my hand
and seal, and cause the same to be inrolled in His Majesty's High Court of
Chancery within two calendar months next and immediately after the date of
the said Letters Patent, that then the said Letters Patent, and all liberties
and advantages whatsoever thereby granted, shall utterly cease, determine,
and become void, as in and by the same, relation being thereunto had, may
more fully and at large appear.

page_text: NOW KNOW YE, that in compliance.. with. the said proviso, I, the said
Charles Coldridge, do hereby declare that the nature of my said Invention,
and the manner in which the same is to be performed, are particularly
described and ascertained in manner following (that is to say) :-
My Invention consists in an Improved Kitchen Grate and Apparatus, which
is represented in the different views of the explanatory Drawing of this
Specification.
First, I do so construct and dispose one, two, or more top doors, shutters, or
covers, that they may apply to the upper part-of the fireplace, either separately
or together, and enclose it either in the whole extent of its length or in part,
as may be required; and I do also so construct and dispose one, two, or
more front doors, shutters, or flaps, that they may apply to the front part of the
fireplace either separately or together, and enclose it either in the whole extent
or in part, as may be required. And I declare, I apply these aforesaid doors,
shutters, flaps, or covers respectively to the front and to the top of the fire-
place for the purpose, and having for my object in so doing,-First, the
transforming the kitchen grate (or, such part of it which by means of the said
separate, doors, shutters, flaps, or covers, may be enclosed), into a perfect stove,
at the pleasure of the operator; and secondly, to use the aforesaid front
doors, shutters, flaps, or covers when let down to an horizontal position, and
there supported, for the purposes of dripping pan, stand, or footman. I further
declare that I do so form and construct, and do dispose and place upon or
about my said kitchen grate and apparatus, a boiling vessel; fountain, and
cistern or cisterns, as that the water it contains may be kept constantly heated,
whether the apparatus be used as a stove or a common kitchen grate; and that
I do place it in such a part of the apparatus that it requires no additional
length or depth to that which the apparatus occupies without it. And I do
make this arrangement with the objects,-First, of applying the space it
would occupy in front of the apparatus to other useful purposes; and secondly,
to lessen the cost of the apparatus to the consumer. The particular con-
struction and arrangement of the parts of my said apparatus are shewn by the
following description of them, with reference to those Figures of the expla-
natory Drawing of this Specification by which they are respectively represented.
Figure 1 is a front view of the apparatus, shewing the aforesaid top and
front doors, shutters, flaps, or covers respectively at C, D, and D, D. These
may be attached to or hung upon the kitchen grate by joints, hinges, bolts,
or any of the obvious and well-known methods of performing such work.
D, D, when let down to an horizontal position, may be supported by the
brackets, the bottom of which are seen in the Figure. When D, D, is shut

page_text: up to enclose the front of the fireplace, it may be held in that position
by.catches, springs, bolts, or any other obvious and well-known method of
fastening, easy to disengage. A, is the oven and door; which may be placed
either to the right or left of the kitchen grate or range; B, the. hot plate
over the said oven, which may be made solid or with a hole or holes; G; the-
back of the kitchen grate, which is moveable on two pivots or projecting
supporting pieces at the two lower corners, by which means the boiling vessel,
cistern, or fountain, which is situated behind it, can more easily be removed and
replaced. One or more apertures may occasionally be made in the back to
afford a quicker supply-of-heat to the cistern. H, the cheek of the kitchen
grate, to wind forward and backward, and may be placed either to the right or
left of the grate; I (Figure 4), the false bottom, to be fixed in the smaller
fireplace, or may be made to wind up and down with a rack and pinion; K, the
funnel to carry off the smoke when the apparatus is used as a stove; this
funnel communicates with a flue which passes from the top of the fireplace &
round the oven, and from thence under the bottom of the boiler or cistern, and
up the back thereof to the said funnel K. F is the water cock of the boiler
or cistern shewn at E, in Figure 3; L, L, L, L, are four flue doors, for the
purpose of cleaning out the accumulations of soot and dirt; the number and
situation of these will always depend upon the size of the kitchen grate. M, a
damper in the funnel; and I place a valve of sheet iron in the chimney, to
close it up when the apparatus is used as a stove, but is open when used as a
common kitchen grate.
In Figure 2 the same letters of reference mark the same parts of the
apparatus respectively. In this Figure the kitchen grate is represented as
enclosed by shutting close the doors or covers C, C, and D, D, and is
transformed into a stove. This Figure being only intended to shew the
transformation of the kitchen grate into a stove, the oven door and the small
parts shewn in Figure 1 are not repeated.
Figure 3 is an end view of the grate, shewing the situation of one or more
boiling vessels or cisterns E for hot water, placed immediately behind in
contact with the iron back of the kitchen grate, and to receive part of the
heat through the said back and the pipe P, by which water passes from the
cistern by the cock F. This pipe may be brought out at any more convenient
part of the apparatus.
In witness whereof, I, the said Charles Coldridge, have hereunto set my
hand and seal, this Ninth day of September, in the year of our Lord
One thousand eight hundred and fifteen.
CHARLES COLDRIDGE. (L.s.)
