IMPROVED APPARATUS FOR THE PURPOSE OF COOKING, WHICH I DESIGNATE A PHILO- SOPHICAL COOKERY
Year: 1820

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
Cook, of Brighton, in the County of Sussex, Engineer, send greeting.
WHEREAS His most Excellent Majesty King George the Fourth did, by
His Letters Patent under the Great Seal of that part of the United Kingdom.
of Great Britain and Ireland. called England, bearing date at Westminster,
the Twenty-ninth day of April, in the first year of His reign, give and grant
unto me, the said Thomas Cook, my exors, adñiors, and assigns, His, especial
licence, full power, sole privilege and authority, that I, the said Thomas
Cook, my exors, admors, and assigns, during the term of years therein meu-
tioned, should and lawfully might make, use, exercise, and vend, within
England, Wales, and the Town of Berwick-upon-Tweed, my Invention of an
"IMPROVED APPARATUS FOR THE PURPOSE OF COOKING, WHICH I DESIGNATE A PHILO-
SOPHICAL COOKERY;" in which said Letters Patent there is contained a proviso,
that if I, the said Thomas Cook, shall not particularly describe and ascertain.
the nature of my said Invention, and in what manner the same is to be per-
formed, 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 six.
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, will more fully and at.
large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Thomas Cook, do hereby declare that the nature of my said Invention, and.

page_text: the manner in which the same is to be performed, are particularly described
and ascertained in the following description thereof (that is to say) :-
My improved apparatus for the purpose of cooking consists of a fire grate
with various chambers, flues, and other parts, as berein-after described.
The Drawing, Fig. 1, represents an elevation of the external appearance of
that part of the apparatus which I usually fix within the opening of the fire-
place. Fig. 2 exhibits the internal structure immediately upon the front or
external part being removed, where w, w, are two standard frames, the bottoms
of which are fixed in mortices, shewn at Fig. 7, x, x, and their top by hold-
fasts extending to the chimney back. To these standards the fronts at z, z,
together with the oven & other partitions are attached. Fig. 3 is a section
parallel to the front, but more remote than Fig. 2, shewing particularly the
construction of the flues. Fig. 4 is a section cut through the middle at the
dotted line X, X, Fig. 1, at right angles to the front, shewing the situation of
the parts and passages relative to the front. Fig. 5 is also a section at right
angles to the front cut through the roasting closet and parts above at the
dotted line. Y, Y, Fig. 6, is a section, likewise at right angles to the front,,
cut through the hot closet and parts above at the dotted line Z, Z. Fig. 7 is
a horizontal section cut through upon the plane of the hobs; and Fig. 8 is a
representation of the side of the range. The letters refer to the same parts
respectively in every Figure. a, a, a, a, a, are the bars of the range, to be
taken out at pleasure, the ends of which are made smaller, and rest on notches.
b, b, b, &c. on the sides of the range (see Fig. 8); c, c, are the sliding cheeks,
the shanks of which pass through openings in the sides at C, Fig. 8, and
which shanks are perforated with holes for the purpose of being pushed back-
ward and forward by the poker or other lever, and are kept steady, as in a
groove, by means of the before-mentioned opening C and steady pins 1, 1,
Fig. 2; the bottom of the range itself is formed by a flat bar, resting also on
the side, as seen at m in Fig. 8, immediately behind which is the grating V,
Fig. 3.
A is the roasting closet, closed by the front of its carriage in Fig. 1,
described more particularly in Fig. 5. B is a hot closet, closed by a door with
proper fastenings, as seen in Fig. 1. C and D are hot-plate closets for boil-
ing, stewing, &c, with doors that slide upwards in grooves P, P, seen in
Figs. 5 and 6, acted upon by springs n, n, n, n. E and F are ovens, closed
with falling doors, seen in Fig. 1. G is a boiler at the back of the range
above the level of the hobs, represented by dottings only, it being behind a
plate of iron, and out of sight. A fire being made in the range, that portion
of the smoke which is not consumed will pass, accompanied by heat) through
the flue H, underneath the sliding plate fand the boiler G, which plate and

page_text: '
boiler becomes heated by that means. This plate passes under the boiler,
and may be drawn out more or less at pleasure. g, g, and h, h, are hobbs or
platforms, being part of the framing of the apparatus, seen more fully at
Fig. 7, where, as well as the sliding plate f, the loose plates i & k are seen
resting upon rebates, Figs. 1 and 2. I is an opening or main flue, by means of
which the principal heat passes from the fire into other flues, shewn in Fig. 3,
in describing which it may be observed, from the entrance at I, the whole or
any portion of the heat may be directed through either of the flues following by.
regulating their respective dampers. The flue I, q, q, heats the top of the
roasting closet. A, the bottom and left side of the boiling closet C, and same:

boiler; from whence, branching into two, it passes up on each side the said.
boiler to its top, where again joining into one flue, it passes up to the damper,
and into the main chimney in the most convenient way. This boiler is made
to communicate by a pipe with the boiler G, from whence it will derive its
supply of water, boiler G being replenished by, another pipe communicating
with a cistern in the usual way. A representation of this oval boiler and
flues, as fixed in brickwork, is shewn by Fig. 9, and its scraper Fig. 10. At
S, through the round aperture J, a communication is formed with the flues
t, t, & v, v. The heat, in its progress to the latter flues, is brought to act with
considerable force underneath the boiling plate K, when, if circumstances
require it, its round lid and ring may be temporarily renewed, and any vessel.
to be heated in haste may be placed over the aperture thereby formed. The
oven F will at same time be heated in the most uniform manner. In order
to keep the flucs t, t, and v, v, clear of soot, a scraper is attached, the handle
or rod connected with which, together with the handles of the steam dampers,
are seen above the said oven in Figure 1. The flue q, q, is cleaned in like
manner, and the closet C and oven E are also supplied with their little flues
and dampers to let the steam or other effluxion escape up the chimney.
When otherwise offensive, the said little flues and dampers are represented in
Figures 5 and 6. The roasting closet is likewise furnished with a very small
apperture or flue to carry off its effluvia; but no damper need be applied.
This may issue from the back near the top of this closet, seen in Fig. 5.
That part of the flue I, q, which is immediately over the roasting closet, has
likewise its scraper, the handle of which is seen at v, Fig. 1. The fire dampers

page_text: in their respective flues should be placed as high as convenience will admit,
and therefore it is unnecessary herein to represent them in any particular
situation. Above the opening, over the range, and within the chimney, is a
door and frame, which door may be raised more or less by means of its
handle having notches to rest on the frame. Through this door frame the
chimney may be swept, &c. The door is somewhat elevated in Fig. 4, from
the oval boiler, Fig. 9, by means of a pipe. For that purpose steam may be
conducted to any convenient situation to a steam boiler. Fig. 11 external
view, & Fig. 12 section, in which 1 is a cover fixed in woodwork, with a steam-
pipe & stopcock 2. 13 is the bottom vessel or receptacle for meat placed on
a bracket sliding up and down by means of the pulley & balance weight 5,
& rendered steamtight when closed by the water groove 6 having a vent pipe
conducting to the chimney.
In the foregoing Drawings and explanation the roasting closet is repre-
sented as on the left, and the hot closet, &c. on the right-hand side; but it is
obvious this arrangement may be readily reversed when and where circum-
stances require it.
In witness whereof, I, the said Thomas Cook (party hereto) have here-
unto set my hand and seal, this Twenty-eighth day of October, in the
year of our Lord One thousand eight hundred and twenty.
