AN IMPROVED BOILER FOR HEATING AND KEEPING UP CIRCULATION IN WATER
Year: 1857

page_text: LETTERS PATENT to Abram Seward and Charles Seward, of Lancaster,
in the County of Lancaster, Manufacturers, for the Invention of "AN
IMPROVED BOILER FOR HEATING AND KEEPING UP CIRCULATION IN WATER."
Sealed the 12th March 1858, and dated the 16th September 1857.
PROVISIONAL SPECIFICATION left by the said Abram Seward at the
Office of the Commissioners of Patents, with his Petition, on tho
16th September 1857.
We, ABBAM SEWARD and CHARLES SEWARD, of Lancaster, in the County of
Lancaster, Manufacturers, do hereby declare the nature of the said Invention
for "AN IMPROVED BOILER FOR HEATING AND KEEPING UP CIRCULATION IN WATER,"
to be as follows:-
The improved boiler is formed by combining two similar upright castings
with sets of horizontal pipes, as follows:-The upright castings are formed
hollow and with a number of sockets, into which are cemented the ends of a
corresponding number of horizontal pipes, the length of which determines the
capacity of the boiler. Of these pipes there are two side sets, in each of
which the pipes are arranged one above another, and three transverse sets, in
each of which they are arranged side by side. The castings are also furnished
with suitable inflow and outflow pipes. The fire is placed upon the lower set
of transverse pipes, and the flame and hot gases from it pass between the
lower and the middle set; the spaces between the pipes of the middle set
being closed up return to the front between the middle and upper set, and
again pass to the back above the upper set, finally passing off by the chimney.

page_text: The ends of the several sets of pipes open into the hollow castings, and the
water as it is heated is compelled to circulate through the pipes and castings,
and away through the outflow pipe or pipes.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Abram Seward in the Great Seal Patent Office on the
16th March 1858.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, ABRAM
SEWARD and CHARLES SEWARD, of Lancaster, in the County of Lancaster,
Manufacturers, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Sixteenth day of September, in the year of our Lord
One thousand eight hundred and fifty-seven, in the twenty-first year of Iler
reign, did, for Herself, Her heirs and successors, give and grant unto
us, the said Abram Seward and Charles Seward, Her special licence that
we, the said Abram Seward and Charles Seward, our executors, adminis-
trators, and assigns, or such others as we, the said Abram Seward and
Charles Seward, 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 "AN IMPROVED
BOILER FOR HEATING AND KEEPING UP CIRCULATION IN WATER," upon the
condition (amongst others) that we, the said Abram Seward and Charles
Seward, or one of us, our executors or administrators, by an instrument in
writing under our, or their, or one of our or 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.
-
NOW KNOW YE, that we, the said Abram Seward and Charles Seward,
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
hereunto annexed, that is to say:-
.
The improved boiler is formed by combining two similar upright castings
with sets of horizontal pipes, as follows:-The upright castings are formed

page_text: hollow and with a number of sockets, into which are cemented the ends of a
corresponding number of horizontal pipes, the length of which determines the
capacity of the boiler. Of these pipes there are two side sets, in each of
which the pipes are arranged one above another, and three transverse sets, in
each of which they are arranged side by side. The castings are also furnished
with suitable inflow and outflow pipes. The fire is placed upon the lower set
of transverse pipes, and the flame and hot gases from it pass between the
lower and the middle set; the spaces between the pipes of the middle set
being closed up return to the front between the middle and upper set, and
again pass to the back above the upper set, finally passing off by the chimney.
The ends of the several sets of pipes open into the hollow castings, and the
water as it is heated is compelled to circulate through the pipes and castings
and away through the outflow pipe or pipes.
Our improved boiler is represented in the Sheet of Drawings hereunto
annexed, of which Figure 1 is a front elevation; Figure 2, a transverse
section; Figure 3, a longitudinal section; and Figure 4, a sectional plan.
In these Figures similar letters are applied to similar parts.
A and B are the two upright castings which form the ends of the boiler, and
C, D, E, are respectively the lower, middle, and upper sets of tubes, the ends
of which are all cemented into sockets in the castings A and B. By increasing
or diminishing the lengths of these tubes the capacity of the boiler may
manifestly be increased or diminished. F and G are the side sets of pipes;
and I are the inflow and outflow pipes respectively. The fire is lighted
upon the tubes C, and the flame and gases pursue the course indicated by the
arrows in Figure 3. The brickwork K on each side of the boiler is placed
about 2 inches from the side pipes, so that the fire may play around them.
And having now described the nature of the said Invention, and in what
manner the same is to be performed, we declare that we claim the construction
of a boiler composed of two upright end castings, with sets of horizontal pipes
or tubes combined therewith, in the manner herein-before described.
In witness whereof, we, the said Abram Seward and Charles Seward,
have hereunto set our hands and seals, this Fifteenth day of March,
One thousand eight hundred and fifty-eight.
ABRAM SEWARD.
