Year: 1863

page_text: LETTERS PATENT to Henry Brinsmead, of Ipswich, in the County of
Suffolk, for the Invention of "IMPROVEMENTS IN COOKING APPARATUB."
Sealed the 29th December 1863, and dated the 3rd July 1868.
PROVISIONAL SPECIFICATION left by the said Henry Brinsmead at the
Office of the Commissioners of Patents, with his Petition, on the 3rd July
1868.
I, HENRY BRINSMEAD, of Ipswich, in the County of Suffolk, do hereby
declare the nature of the Invention for "IMPROVEMENTS IN COOKING APPARATUS,"
to be as follows:-
. This Invention has for its object improvements in cooking apparatus. For
these purposes
when arranging and constructing apparatus for cooking where
an oven is used, apparatus for boiling and steaming is combined therewith in
such. manner that more or less of the boiling apparatus may, with facility, bu
brought into action, and be heated by the same means as are employed for
heating the oven.
The Invention is peculiarly applicable for cooking when gas is employed,
but apparatus may be constructed according to my improvements wherein
other means of heating are resorted to. The oven used may be of an ordinary
construction, and the same may be heated by gas in the usual manner; but,
according to my Invention, provision is made for the passage of tubes, pro-
jecting from the boilers into the lower compartment of the oven above the gas
burner or burners. The boilers are each formed separate from the oven,
in order to admit of each boiler, when in use, being closed up. to or at a
greater or less distance from the oven, according as it is desired that a greater

page_text: At
or less quantity of heat should at any time be applied thereto. Each boiler is
constructed with one or more projecting tubes at or near their lower parts, it
being preferred that the arrangement should be such that the heated water
shall circulate or flow in these projecting tubes to and from the boiler.
the sides of the oven, where the boilers are applied, there are openings formed
for the passage of the projecting tubes of the boilers into the lower part or
compartment of the oven, and according as these tubes are caused to enter
more or less into the enclosed space at the lower part of the oven, so will be
the result in the boiler or boilers for the time being in use. The apparatus
for boiling and steaming may, in other respects, be similar to those heretofore
employed for like purposes. When the oven is not to be heated by gas, then
a.suitable fire-place is to be applied to heat the oven and apparatus connected
therewith.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Henry Brinsmead in the Great Seal Patent Office on the
2nd January 1864.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, HENRY
BRINSMEAD, of Ipswich, in the County of Suffolk, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Third day of July, in the year of our Lord One
thousand eight hundred and sixty-three, in the twenty-seventh year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Henry Brinsmead, Her special licence, that I, the said Henry Brinsmead,
my executors, administrators, and assigns, or such others as I, the said Henry
Brinsmead, my executors, administrators, and assigns, should at any time
agree with, and no others, from time to time and at all times thereafter,
during the term therein expressed, should and lawfully might make, use,
exercise, and vend, within the United Kingdom of Great Britain and Ireland,
the Channel Islands, and Isle of Man, an Invention for "IMPROVEMENTS IN
COOKING APPARATUS," upon the condition (amongst others) that I, the said Henry
Brinsmead, my executors or administrators, by an instrument in writing under
my, or their, or one of their hands and seals, should particularly describe and
ascertain the nature of the said Invention, and in what manner the same was
to be performed, and cause the same to be filed in the Great Seal Patent
Office within six calendar months next and immediately after the date of the
said Letters Patent.

the nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following.
statement thereof, that is to say :-
This Invention has for its object improvements in cooking apparatus. For
these purposes, when arranging and constructing apparatus for cooking, where
an oven is used, apparatus for boiling and steaming is combined therewith in
such manner that more or less of the boiling apparatus may, with facility, be
brought into action, and be heated by the same means as are employed for
heating the oven..
.
The Invention is peculiarly applicable for cooking when gas is employed,
but apparatus may be constructed according to my improvements wherein
other means of heating are resorted to. The oven used may be of an ordinary
construction, and the same may be heated by gas in the usual manner, but:
according to my Invention provision is made for the passage of tubes pro-
jecting from the boilers into the lower compartment of the oven, above the
gas burner or burners. The boilers are each formed separate from the oven
in order to admit of each boiler when in. use being closed up to or at a
greater or less distance from, the oven, according as it is desired that a greater
or less quantity of heat should at any time be applied thereto. Each boiler
is constructed with one or more projecting tubes at or near their lower parts
it being preferred that the arrangement should be such that the heated
water shall circulate or flow in these projecting tubes to and from the
boiler. At the sides of the oven where the boilers are applied there are
openings formed for the passage of the projecting tubes of the boilers into
the lower part or compartment of the oven, and according as these tubes
are caused to enter more or less into the enclosed space at the lower part of.
the oven, so will be the result in the boiler or boilers for the time being in use.
The apparatus for boiling and steaming may, in other respects, be similar to those
heretofore employed for like purposes. When the oven is not to be heated:
by gas then a suitable fire-place is to be applied to heat the oven and apparatus.
connected therewith.
Having described the nature of my Invention, I will now describe the
accompanying Drawing, which illustrates one method of carrying out my
Invention when gas is. the heating power used.
Figure 1 is a sectional plan; Figure 2 is a front elevation; Figures 3
and 4 are side elevations. The same letters refer to the same parts in all the
Figures.
a is the oven or main receptacle.for.baking and roasting: b. b. b. are boilers

page_text: having tubes c, c, projecting laterally from the bottom 3. d, d, are the gas
burners; e, e, are tubes leading to the burners, having cocks placed near the
front of the apparatus, for. the convenience of the attendant; f is a heat:
distributor, for throwing the heat from the burners beneath it to the sides of:
the oven a; g, 9, are folding leaves forming tables for receiving plates,
dishes, &c., and are held up by the swinging brackets h,h; i is a sight-hole;
for observing the progress of the cooking without opening the oven door. A:
suitable number of burners are placed at the bottom of the main receptacle.
or oven a, the heat from which is thrown to the sides of the same by the
distributor f, so as to completely surround the articles to be cooked. The
boilers 6 have tubes c projecting laterally from the bottom, which are made to
pass through openings in. the sides of the oven a, and reach over the
burners d, d, which heat the same. It will thus be seen that the same
burners serve for heating the oven a and also for heating the water in the.
three boilers b, b, b. The amount of heat required to be applied to the:
boilers is regulated by shifting them laterally, so that more or less of the
flame from the burners shall strike against the tubes, or by withdrawing them.
bodily away from the side of the oven a, thus either one or all three of the.
boilers may be made to boil rapidly, gently, or merely simmer, or withdrawn
altogether at pleasure. There are burners placed outside of the oven a
for occasions when the oven is not required to be heated; these serve
for heating the boilers, or for any of the other smaller requirements of
cookery.
Having now, described the nature of my Invention, and one method of
performing the same, I would have it understood that I do not confine myself
to the precise form herein described, nor to any particular form whatever ;.
but what I claim is, arranging and constructing apparatus for cooking (where
an oven is used), with an apparatus for boiling and steaming combined
therewith, in such manner that more or less of the boiling apparatus may,
with facility be brought into action, and be heated by the same means as are
employed for heating the oven.
In witness whereof, I, the said Henry Brinsmead, have hereunto set
my hand and seal, this Thirtieth day of December, in the year of our
Lord One thousand eight hundred and sixty-three.
HENRY BRINSMEAD.
