A MACHINE WITH UTENSILS FOR COOKING ON IMPROVED PRINCIPLES
Year: 1792

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES TATE,
of Oxford Street, in the Parish of Saint Mary-le-bone, in the County of Mid-
dlesex, Ironmonger, send greeting..
WHEREAS His most Excellent Majesty King George the Third, by His
Letters Patent under the Great Seal of Great Britain, bearing date at West-
minster, the Second day of March, in the thirty-second year of His reign, did
grant unto me, the said James Tate, His special licence that I, the said James
Tate, during the term of fourteen years therein expressed, should and lawfully
might make, use, exercise, and vend, within that part of the Kingdom of Great
Britain called England, the Dominion of Wales, and Town of Berwick-upon-
Tweed, my Invention of "A MACHINE WITH UTENSILS FOR COOKING ON IMPROVED
PRINCIPLES;" in which said Letters Patent there is contained a proviso, obliging
me, the said James Tate, to cause a particular description 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 next
and immediately after the date of the said in part recited Letters Patent, as in
and by the same, relation being thereunto had, may more fully and at. large
appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
James Tate, do hereby declare, that the nature of my said Invention of a

page_text: Machine with Utensils for Cooking on Improved Principles, is described as
follows; that is to say :-
The machine consists of different improvements in the mode of cooking by
and from an inclosed fire-place or furnace, and the first and principal improve-
ment is the application of a boiler or inclosed vessell, for the purpose of raising
steam, to and with a broiling or stewing plate, and a baking oven, the use of
the same fire being extended to the whole, and the steam raised in and by the
said boiler or vessell to be from thence conveyed by a pipe or pipes into the
different other vessells that the victuals are to be cooked in. By this appli-
cation, the fire used for a stewing or broiling plate, either with or without an
oven, is rendred more useful, and cooking from an inclosed fire-place or
furnace rendered more convenient, extended, and complete, and the use of
steam for boiling in seperate vessells obtained in its greatest perfection, and
the improved methods of applying the different vessells cooked in or with to
the boiler or vessell by which the steam is raised, or to the different pipes that
may be found necessary to branch out from the same in any direction, is
described as follows (that is to say):-
First, I make or cause to be made a broiling or stewing pan, with its barrs,
door, and frame, which I cause to be fixed up in the usual manner. I then
cause the boiler for raising the steam to be made with the different pipes or
tubes that may be necessary for conveying the steam to the different vessells
cooked in or with, for filling the boiler with water, and for drawing off the water.
This boiler may be made of many different shapes, or of any particular shape,
so as to come in contact with the stewing or broiling plate, and receive the
force and heat of the fire as soon as it has passed the plate. I then apply
this boiler to the end or side of the stewing plate, to receive the heat and
force of the fire as described above; the application of this inclosed boiler or
vessell for raising steam to act in any manner, or to be fixed in any situation,
so that it be in conjunction with the stewing plate and oven, constitutes the first
and principal improvement in the said machine, or to act with the stewing plate
singly, without the oven, when that part of the machine will not be wanted. I
then cause the baking oven to be made, which may be any of the sorts now in
use. This oven I fix over the boiler, or to the sides thereof, so that it receives
the heat and force of the fire, after it has passed by, over, or under the said
boiler. I then, if required, place registers between the boiler and the oven,
and between the stewing plate and the boiler; these registers, by means of
seperate flues or funnells, will turn the fire from the boiler when that is not
wanted to be used, or from the oven in like manner; the whole machine, so

page_text: far as described, may be made of iron or other materials, and fitted and fixed
together with iron flues or funnells, or the different parts may be separately
made and fixed up in brickwork or stone. I then fix one or more pipes or
tubes to the boiler, by which the steam is raised to convey the steam from thence
where the different vessells cooked in or with are to be placed; if but one pipe
is necessary, to this I fix, in different places according to the number of vessells
intended to be used, so many short pieces of cylindrical or parellel pipes, each
containing a valve, either with a spring to keep the said valve to its seat, or
with a joint axis or pivots of any sort, so that the said valve will be pressed
forward or fall down into its proper seat, when not pushed or forced back by
something applied to the open end or cavity of the said pipe for that purpose;
this valve may be also made without any spring, joint, axes, or pivots, but to fall
into its seat by the force of its own weight; and then its pipe or tube must be fixed
so much on the descent as to permit the said valve to fall into its seat by the force
of its own weight; any of the above described valves, or any of the water stops,
except the common stop (cock) being applied or fixed in each of the said pipes
leading from the boiler, so as to turn or open by the introduction of any pro-
jection into the open end or cavity of the said pipes, or by any external pressure
communicating with the said valves by means of spindles or rods will answer
the intended purpose; the application of a valve of any sort (except a common
stopcock, in this situation, and the preparations herein-after to be described, as
fixed to each of the vessells cooked in or with, to receive the ends of these
pipes with the valves, constitute the next principle improvement in the said
machine. I then cause to be made the vessells cooked in or with. These
may be of any materials or any shape. To each of these vessells, I fix a
double cylendricular or parellell tube, the cavity of the inner tube to admit
the steam into the vessell, and the space between the inward and outward
tubes to be wide enough to receive or admit the end of the tube with the
valve, as already described; the space between the inward and outward
tubes to be partly filled with cork or any other spongy or elastick substance;
so that when the vessells are applied the end of the pipe with the valve is
pressed between the cavity of the other two pipes till met by the cork or other
substance, by which they form a tight junction so as to prevent the steam from
passing any other way but into the vessell. One part of the end of the inward
tube must be made to project further than the rest; this projection, when the
vessell is applied, pushes the valve in the other pipe from its seat, and by that.
means opens a free passage for the steam to pass from the boiler to the different
vessells cooked in. The utility of this improved method of applying the vessells

page_text: must be very evident, as the very act of applying the vessells to the pipes
removes the valves, and the machine is at work; and by taking away or
removing the vessels from their places, the valves shut without further trouble,
and the stream is kept in. In place of the double cylindrical tube fixed to the
vessells cooked in, a single tube may be applied with a shoulder to admit the
cork or other substance to be fixed or placed on; this mode would answer the
same purpose of the other, but the cork or other substance would be more
liable of being spoiled or broken off. In the above description the whole
machine is described as if to be made of new materials; but as the improve-
ments in the said whole machine consists only in the application of the boiler
for raising the steam, and the new or improved mode of applying the vessells
cooked in or with to the said boiler the said improved part or parts are to be
applied to broiling or stewing plates and baking ovens.that have been already
fixed or set up. Where there is not occasion to make the whole machine of new
materials, or to stewing plates singly, the application of a boiler of this description,
and in this situation for raising steam, is attended with many advantages in
cooking from an inclosed fire-place or furnace, more than can possibly be obtained
by the use of a copper or other open vessell, in conjunction with a boiler plate
and a baking oven, particularly as a boiler of this description, of very small
dimensions, will raise steam to boil more victuals than could be done in a very
large open vessell in the common way, exclusive of heating a closet, and therefore
admits the whole machine to be placed more immediately to the influence of the
fire, and an opportunity given of placing the oven immediately over the boiler,
or the boiler over the oven, if circumstances so require, by which less fuel
required and the advantage of boiling by steam in separate vessells obtained
without the stream of one vessell passing through another; and by the improved
method of applying the vessells cooked in or with to the said boiler by which the
steam is raised or to the pipe or pipes leading from the same, the whole will be
rendered the most complete and convenient machine for cooking from an inclosed
fire-place or furnace yet invented, and may be applied to other useful purposes,
such as warming rooms.
In witness whereof, I, the said James Tate, have hereunto set my hand
and seal, this Thirty-first day of March, in the year of our Lord One
thousand seven hundred and ninety-two.
