IMPROVEMENTS IN BOILERS USED FOR HEATING AND CIRCULATING WATER
Year: 1854

page_text: LETTERS PATENT to John Packham, of 68, Western Road, Brighton, for
the Invention of "IMPROVEMENTS IN BOILERS USED FOR HEATING AND
CIRCULATING WATER."
Sealed the 21st November 1854, and dated the 25th May 1854.
PROVISIONAL SPECIFICATION .left by the said John Packham at the
Office of the Commissioners of Patents, with his Petition, on the
25th May 1854.
I, JOHN. PACKHAM, of 68, Western Road, Brighton, do hereby declare the.
nature of the Invention for "IMPROVEMENTS IN BOILERS USED FOR HEATING AND.
CIRCULATING WATER" to be as follows:-
!
This Invention consists of a peculiar combination of parts of a boiler used
for heating and circulating water, by which an extended heating surface is
obtained. For this purpose the front and back ends of the boiler are hollow,
water spaces, there being an opening through the front into the fire-place.or
furnace.
:
The two ends are combined together by pipes, which enclose the fire-place.
or furnace. The upper part of the boiler above the pipes is hollow, and con-
stitutes a water space, which opens into the back and front ends of the boiler.
The flow pipe or pipes are fixed to the upper part of the boiler, and the return
pipe or pipes are connected with the end or ends of the boiler -near the lower
part thereof. The fire bars may be solid, or they may be hollow, and connect.

page_text: the front and back ends of the boiler. Thro' the upper part of the boiler
there is formed a tubular opening, which descends down into the fire-place or
furnace, and rises sufficiently above the top of the boiler to contain a considerable
supply of fuel, which will descend into the fire-place as that which is below is
consumed, but that which is in the upper part of the tube will not be consumed,
in consequence of the upper or charging end being kept closed. The boiler is
set in brickwork, in such manner that a flue is made in the brickwork on either
side near the upper part of the fire-place, and in a direction from back to front;
the flue then rises and passes back over the top of the boiler to the chimney,
which is at the back end of the boiler.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Packham in the Great Seal Patent Office on the
22nd November 1854.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOIN
PACKHAM, of 68, Western Road, Brighton, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-fifth day of May, in the year of our Lord
One thousand eight hundred and fifty-four, in the seventeenth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said John Packham, Her special licence that I, the said John Packham,
my my executors, administrators, and assigns, or such others as I, the said
John Packham, my exccutors, administrators, and assigns, should at any
time agree with, and no others, from time to time and at all times there-
after 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
BOILERS USED FOR HEATING AND CIRCULATING WATER," upon the condition
(amongst others) that I, the said John Packham, by an instrument in
writing under my hand and seal, 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 I, the said John Packham, do hereby declare 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):-

page_text: This Invention consists of a peculiar combination of parts of a boiler used
for heating and circulating water, by which an extended heating surface is
obtained. For this purpose the front and back ends of the boiler are hollow
water spaces, there being an opening through the front into the fire-place or
furnace. The two ends are combined together by pipes which enclose the fire-
place or furnace. The upper part of the boiler above the pipes is hollow, and
constitutes a water space, which opens into the back and front ends of the
boiler. The flow pipe or pipes are fixed to the upper part of the boiler, and
the return pipe or pipes are connected with the end or ends of the boiler near
the lower part thereof. The fire bars may be solid, or they may be hollow,
and connect the front and back end of the boiler. Through this upper part of
the boiler there is formed a tubular opening, which descends down into the
fire-place or furnace, and rises sufficiently above the top of the boiler to contain
a considerable supply of fuel, which will descend into the fire-place as that
which is below is consumed; but that which is in the upper part of the tube
will not be consumed, in consequence of the upper or charging end being kept
closed. The boiler is set in brickwork, in such manner that a flue is made in
the brickwork on either side near the upper part of the fire-place, and in a
direction from back to front; the flues then rise and pass back over the top of
the boiler to the chimney, which is at the back end of the boiler.
Having thus stated the nature of my Invention, I will proceed to explain
the manner of performing the same.
DESCRIPTION OF THE DRAWING.
Figure 1 shows an external view of the setting of a boiler constructed
according to my Invention. Figure 2 is a longitudinal section of the boiler
and setting; and Figure 3 is a transverse section of the same. The boiler
is made with two hollow ends a and b; through the front one is an opening
into the furnace. Each of these two hollow ends is cast with sockets, to
receive the ends of the several pipes c, c; and the front end is formed with
two additional sockets, to receive the ends of the short pipes projecting from
the upper water space d; or both ends may be similarly connected to the two
end water spaces. The outer plates of the two water spaces are separate, and
are affixed by screws, after the ends of the pipes have been made water-tight in
the sockets. The upper water space d is cast or made with a passage through
it, through which the feed funnel or pipe e is passed. f. f, are two flow pipes,
in connection with the upper water space d of the boiler; and g is the return
pipe, in connection with the back hollow end 6 of the boiler.
I would remark that, although the upper hollow water space d may be

page_text: g
connected with the front and back water spaces, I prefer that the return pipe
should be connected with the back water space b, and that the upper water
space & should only be connected with the front water space a, as by such an
arrangement the whole return water is forced to take a more circuitous course
to the flow pipes than it otherwise might; but this mode of connecting the pipes
may, when desired, be varied, and details may be altered without departing
from my Invention..
Having thus described the nature of my Invention, and the manner of
performing the same, I would have it understood that what I claim is, the
combination of parts herein described.
In witness whereof, I, the said John Packham, have hereunto set my
hand and seal, this Twenty-first day of November, in the year of our
Lord One thousand eight hundred and fifty-four.
Witness,
ARTHUR NICHOLS.
