Year: 1854

page_text: LETTERS PATENT to Thomas Knight and Stephen, Knight, both of
Southwark, in the County of Surrey, Manufacturers, for the Invention
of "IMPROVEMENTS IN APPARATUS FOR HEATING WATER FOR BATHS AND OTHER
-PURPOSES:"-
Sealed the 18th May 1855, and dated the 29th November 1854.
PROVISIONAL SPECIFICATION left by the said Thomas Knight and
Stephen Knight at the Office of the Commissioners of Patents,, with.
their Petition, on the 29th November 1854.
We, THOMAS KNIGHT and STEPHEN KNIGHT, both of Southwark, in the
County of Surrey, Manufacturers, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN APPARATUS FOR HEATING WATER FOR BATHS AND
OTHER PURPOSES," to be as follows:-
Our apparatus consists of a boiler and 'grate, and. fór convenience sake we
can so construct them as that they may be readily fitted in an ordinary fire-
place and chimney, the grate answering the purposes of an ordinary fire. when
required. The boiler itself consists of a double four-sided vessel, two sides of
which are connected by tubes, through which water circulates, and which are
placed across the chimney, so that the flame and products of combustion
are made to pass between them in their passage into the flue. There are three
pipes connected to our boiler; one at bottom, for the admission of water.

page_text: from a cistern; and in order to distribute the water through the boiler, we place
a curved or bent plate just over the month of this lower pipe. The other two
pipes are fitted to the upper part of the boiler; one leading up to the cistern,
and merely connected with the side of the boiler; and the other to-the-bath-or-
other vessel, to which-hot-water-is-to-be-supplied. This pipe passes through
the side of the boiler, and is connected with a box, forming the top of the
boiler, which also contains a division plate through the centre from side to
side. There is also a stop or bent plate placed near the top, on the opposite
side of the boiler to that which the pipes enter; these stops are for the
purpose of causing the water to pass over the fire before it can be drawn out
of the pipe to supply the bath, &c.
SPECIFICATION in pursuance of the conditions of. the Letters Patent, filed
by the said Thomas Knight and Stephen Knight in the Great Seal Patent
Office on the 29th May 1855.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, THOMAS
KNIGHT and STEPHEN KNIGHT, both of Southwark, in the County of Surrey,
Manufacturers, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-ninth day of November, in the year of our
Lord One thousand eight hundred and fifty-four, in the eighteenth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto us,
the said Thomas Knight and Stephen Knight, Her special licence that we, the
said Thomas Knight and Stephen Knight, our exccutors, administrators, and
assigns, or such others as we, the said Thomas Knight and Stephen Knight,
our 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 APPARATUS FOR
HEATING WATER FOR BATHS AND OTHER PURPOSES," upon the condition (amongst
others) that we, the said Thomas Knight and Stephen Knight, or one of us,
by an instrument in writing under our hands and seals, or under the hand and
seal of one of us, 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.

page_text: NOW KNOW YE, that we, the said Thomas Knight and Stephen Knight,
do hereby declare the nature of our said Invention, and in what manner the
same is to be performed, to be particularly described and ascertained in and
by the following statement thereof, reference being had to the Drawings here-
unto annexed, that is to say:
. Our Invention consists in constructing an apparatus composed of a boiler
and grate, which can be so formed that they may be readily fitted in an
ordinary fire-place and chimney, the grate in this case answering the
purposes of an ordinary fire-grate when required. The boiler itself consists of
a double four-sided vessel, the inner sides of which are connected by tubes,
through which water circulates, and which are placed across the chimney, so
that the flame and products of combustion are made to pass between them in
their passage into the flue. When the apparatus is applied to the heating of
water for a bath, the bath is connected with a chamber at the upper part
of the boiler by.a pipe suitably situated. The boiler is fed from a cistern, with.
which also it is connected by pipes suitably disposed.
The Drawings hereunto annexed represent our Invention as applied to an
ordinary fire-place and chimney, and arranged to supply a bath or other vessel
with heated water. Figure 1 represents an ordinary front plate; Figure 2;
the same plate with our boiler applied behind it; Figure 3, a vertical trans-
verse section of the apparatus, taken through the boiler; Figure 4, a front
view of the apparatus, with the front plate removed, and a blower furnished
with balance weights applied; Figure 5, an outside view of one side of the
apparatus; Figure 6, a view of the same side, with the outside plate off';
Figure 7, a view of the opposite side, with the outside plate off; and Figure 8,
a horizontal section, taken through the chamber at the top. In all these Figures
the same letters are employed to represent like parts. In the arrangement
here shewn there are three pipes a, b, c, connected to the boiler. The first, a,
situated at the bottom, is for the admission of water from the feed cistern, and
just over the mouth of it is placed a curved or bent plate d, the object of which
is to cause the water to pass through the tubes of the boiler before finding its
exit. The other two pipes, b, c, are fitted to the upper part of the boiler; one,
c, leading up to the cistern, and being connected to the side of the boiler, and
the other, b, being connected to the bath or other vessel to which the water is
to be supplied. This pipe b passes through the side of the boiler, and is
connected with the box or chamber e, which forms the top of the boiler, and
which contains a division plate f through the centre from side to side, so that
water is drawn off from that half only of the chamber e which the pipe benters.
There is also a stop or bent plate g placed near the top, on the opposite side of

page_text: the boiler to that which the pipes enter, which stop or plate is for the purpose
of causing the water to pass over the fire before it can enter that division of the
chamber e from which the pipe-b-leads. The apertures or spaces
through
the chamber-e-are-for_the_passage of the flame and products of conibustion
after they have passed among the transverse tubes i, i.
And having now described the nature of our said Invention, and in what
manner the same is to be performed, we declare that what we claim is;
the construction of a heating apparatus, composed of a grate and a boiler
furnished with suitable tubes and passages, as herein-before described, such
apparatus being capable of ready adaptation to an ordinary fire-place and
chimney; the grate in this case answering the purposes of an ordinary fire-
grate when required.
In witness whereof, I, the said Stephen Knight, for myself and on
behalf of the said Thomas Knight, have hereunto set my hand and
seal, this Twenty-ninth day of May, One thousand eight hundred and
fifty-five.

STEPHEN KNIGHT. (L.S.)
