PROVISIONAL SPECIFICATION left by the said William Grandage
Ramsden at the Office of the Cominissioners of Patents, with his
Petition, on the 3rd March 1860.
I, WILLIAM GRANDAGE RAMSDEN, of Liverpool, in the County of Lancaster,
Engineer, do hereby declare the nature of the said Invention for "AN
IMPROVED BOILER OR APPARATUS FOR GENERATING AND SUPERHEATING STEAM. OB
HEATING WATER OR OTHER FLUIDS UNDER PRESSURE," to be as follows (that is to
say):
To form the said boiler or apparatus, construct two or more chambers to
contain the water or other fluid, the said chambers being formed with one
side flat, and the other sides and ends of semicircular or other shape adapted
to sustain the pressure at which the boiler or apparatus is to be worked;
place the said chambers in pairs, upright, and with the flat sides facing and
parallel to each other at a suitable distance apart, and connect them together
by tubes or pipes passing from one to the other, the said tubes or pipes being
secured to and opening into the said chambers at the ends, so as to allow a
free circulation of the water or fluid from one chamber to the other; place
[Price Sd.]

page_text: the said tubes or pipes in rows from side to side of the chambers, and onc
row above another row to the top of the chambers, leaving sufficient space
between all the said tubes or pipes and rows for the free passage upwards of
the flame or heated air from the fire, which place on a grate or furnace at a
suitable distance below and under the said tubes. According to the quantity
of steam to be generated, combine together a sufficient number of the said
upright chambers connected together in pairs by tubes or pipes, and having a
furnace under as before described. placing them side by side, and connecting
them together at the lower end by a pipe or pipes, or other passage, to allow
the water or other fluid to circulate from one to the other of the chambers so
placed side by side, and connect them at the top by pipes or other passages,
with one or more steam chests or chambers of cylindrical or other approved
form, which steam chests or chambers are arranged in such a position as to
form a passage or uptake for conveying to the chimney the heated air and
products of combustion when they ascend above the before-mentioned rows
of tubes or pipes, and convey the steam from the said steam chests or chambers
to the engine or other machinery for which it is required by a pipe or pipes
attached thereto, and leading downwards from the upper part of the said steam
chests or chambers into the passage or uptake for the heated air, the said
steam pipe or steam pipes being then continued through the said uptake so as
to be exposed to the action of the heated air as it passes to the chimney; after
which the said steam pipe or steam pipes are continued to any point where
the engine is placed close the outer sides of the end pairs of upright chambers
by doors or other fittings as used for this description of work, but in some
cases it is preferred to do this by forming a water space or chamber extending
over the width occupied by the tubes or pipes, the said water spaces or
chambers opening at the ends into the upright chambers. or they may be
completely detached and used as heaters for the feed water, or for the purpose
of distillation. The sides and ends of the furnace or furnaces may be formed
of plating and brickwork, or of water spaces, as may be preferred.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William Grandage Ramsden in the Great Seal Patent Office
on the 1st September 1860.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
GRANDAGE RAMSDEN, of Liverpool, in the County of Lancaster, Engineer, send
greeting.

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 OR APPARATUS FOR GENERATING AND SUPERHEATING STEAM; OR
HEATING WATER OR OTHER FLUIDS UNDER PRESSURE," upon the condition (amongst
others) that I, the said William Grandage Ramsden, my executors or admi-
nistrators. 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.
NOW KNOW YE, that I, the said William Grandage Ramsden, do hereby
declare the nature of my said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and by the
following statement (that is to say):-
To form the said boiler or apparatus I construct two or any other required
number of pairs of chambers to contain the water or other fluid, the said
chambers being formed with one side flat, and the other sides and ends of
semicircular or other suitable shape adapted to sustain the pressure at which
the boiler or apparatus is to be worked. I place the said chambers in pairs
upright, and with the flat sides facing and parallel to each other at a suitable
distance apart, and connect them together by tubes or pipes passing from one.
to the other, the said tubes or pipes being secured to and opening into the
said chambers at the ends, so as to allow of a free circulation of the water or
fluid from one chamber to the other. I place the said tubes or pipes in rows
from side to side of the chambers, and one row above another row to the top
of the chambers, leaving sufficient space between all the said tubes or pipes
and rows for the free passage upwards of the flame or heated air from the fire,
which is placed on a grate or furnace at a suitable distance below and under
the said tubes. According to the quantity of steam to be generated: I com-
bine together a sufficient number of the said upright chambers, and connect

page_text: them together in pairs by the tubes or pipes, having a furnace under them, as
before described. I place them side by side and connect them together at
their lower ends by a pipe or pipes or other suitable passage to allow the water
or other fluid to circulate from one to the other of the chambers so placed side
by side, and I connect them at the top by pipes or other passages with one
or more steam chests or chambers of cylindrical or other approved form, which
steam chests or chambers I arrange in such a position as to form a passage
or uptake for conveying to the chimney the heated air and products of com-
-bustion when they ascend above the before-mentioned rows of tubes or pipes,
and I convey the steam from the said steam chests or chambers to the engine
or other machinery for which it is required, by a pipe or pipes attached
thereto, and leading downwards from the upper part of the said steam chests
or chambers into the passage or uptake for the heated air, the said steam pipe
or steam pipes being then continued through the said uptake, so as to be
exposed to the action of the heated air as it passes to the chimney, after which
the said steam pipe or steam pipes are continued to any point where the
engine is placed. I close the outer sides of the end pairs of upright chambers
by doors or other fittings as used for this description of work; but in some
cases I prefer to do this by forming a water space or chamber extending over
the width occupied by the tubes or pipes, the said water spaces or chambers
opening at the ends into the upright chambers, or they may be completely
detached and used as heaters for the feed water or for the purpose of distil;
lation. The sides and ends of the furnace or furnaces may be formed of
plating and brickwork, or of water spaces, as may be preferred.
That this my said Invention may be the more readily seen and understood,
I have hereunto annexed Drawings in illustration of two modifications of the
application of the same as applied to marine boilers, to which this my said
Invention is peculiarly applicable; like letters and figures marked thereon
having reference to similar parts.
Figure 1 is a vertical sectional clevation of one of my improved marine
boilers or apparatus adapted for the production of high-pressure steam, taken
through the centre of the first pair of chambers from the points a to b,
Figure 2. The apparatus in this Figure is shown set in a leaning position to
allow the steam formed within the pipes (which are first acted upon by the
flame of the fire) to rise to the surface of the fluid; Figure 2 is a side eleva-
tion of the same, one half of which is shown in vertical section taken on
the dotted line c, d, Figure 1; and Figure 3 shows an horizontal section of the
apparatus taken from e to f, and g to h, Figures 1 and 2.
Figure 4 is a vertical sectional elevation of another modification of my

page_text: improved apparatus, also set in a leaning position and adapted for generating
steam of lower pressure than the modification illustrated by Figures 1, 2,
3; and Figure 5 is a top view or plan of the same, shown with the upper
plates removed from to k, so as to partially expose the tops of the vertical
semicircular chambers, and the division plates which form the chambers into
which the steam passes through the openings shown.
A are semicircular chambers (which in Figures 1. 2. and 3 are shown as
narrowed in or contracted at their upper ends). which contain the water or
other fluid to be evaporated, which are connected together by their inner flat
sides by B, tubes or pipes. the ends of which open into the chambers and
allow the water to circulate from one chamber to another: C. two horizontal
semicircular water spaces placed parallel to each other, and into which the
lower ends of the chambers A open: D. two cylindrical chambers mounted
parallel to each other above the water chambers A. the upper ends of which
open thereinto; E. junction pipes or passages connecting the two cylindrical
chambers D, with F an horizontal cylindrical steam chest, the centre of which
is contracted to a less diameter than the end portions, so as not to obstruct the
passage of the products of combustion through the uptake to the chimney:
G, steam dome on the steam chest F; H. steam pipe, extending from the
steam dome down through one of the lower plates of the steam chest F, and
over the transverse pipes B to the steam cylinder or other apparatus; I, the
smoke funnel; K, top or covering plates, which enclose the upper portion of
the apparatus and form the uptake: L, setting of brickwork; M. fire-bars
and dead plate forming grate: N. (Figure 2). furnace doors: 0, enclosing
doors, hinged to the semicircular sides of the chambers A. and which admit
of the horizontal tubes being got at for the purpose of being cleaned on their
outer surface; P, Figures 4 and 5, an enclosed chamber, formed by a double
arch of boiler plates, into which the upper ends of the water chambers A
open, and which is shown divided into three compartments by means of Q.
feather or division plates, which are perforated with R. an opening for the
passage of the steam into the upper compartment: S. a junction pipe, for
carrying the steam from the upper arched chamber into T, a flat oblong
round-edged superheating chamber placed longitudinally within the uptake
immediately above the transverse tubes B, and which superheating apparatus
is constructed with U, a number of small vertical pipes or tubes, through which
a portion of the products of combustion pass: W, Figures 4 and 5 smoke
funnel, which passes through the upper steam chamber.
Having now fully described and ascertained the nature of this my said
Invention. and how I believe the same may be best carried into practical

page_text: effect, I wish it to be understood that I do not confine myself to the precise.
details or relative dimensions herein-before set forth, as they may be consi-
derably varied or modified without departing from the principle of the same;
but what I claim as my Invention is the general arrangement and combination
of the various parts, so as to form an improved boiler or apparatus, substan-
tially and in the manner herein-before described and set forth, or any mere
modification of the same.
In witness whereof, I, the said William Grandage Ramsden, have
hereunto set my hand and affixed my seal, this Thirty-first day of
August, in the year of our Lord One thousand eight hundred and
sixty.
