IMPROVEMENTS IN STEAM BOILERS
Year: 1868

page_text: LETTERS PATENT to James Morris, of Boundary Road, Middles
borough, in the North Riding of the County of York, for the Inven-
tion of "IMPROVEMENTS IN STEAM BOILERS."
Sealed the 15th December 1868, and dated the 27th June 1868.
I, JAMES MORRIS, of Boundary Road, Middlesborough, in the North
Riding of the County of York, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN STEAM BOILERS," to be as follows:-
My Invention has for its object an increase in the power and efficiency
of boilers, as for instance those of the vertical class, and is especially
adapted for those that receive the products of combustion from puddling
or heating furnaces, which are known as stack boilers.

page_text: I use an inner tube or flue extending from the top to the bottom, and
through which the products of combustion pass. This tube swells out
towards the lower part into a chamber, which I prefer to make of a
conical form, the apex of the cone being downwards, and the base being
made convex upwards. Across this chamber a tube, by preference of
cylindrecal form, is fixed, which should be large enough to admit a man's
body, and planted upon this cross tube is a saddle or chamber forming
part of it, and the shape of which corresponds to the shape of the
conical chamber around and above it. From the inner chamber to the
outer one extend tubes, by preference of a conical or cylindrecal form.
These tubes, about eight in number (more or less), are arranged at about
equal distances apart all round the chambers. I prefer to make them
radially outwards, and with their larger end upwards. The outer shell
of the boiler has at least two man-holes, one in the upper part of the
boiler and another just opposite the cross tube aforesaid, in order to gain
entrance to it. I vary the construction by making the outer chamber
of a cylindrecal form with convex ends, and the inner one to correspond.
In this case I insert a set of tubes below, similar and in addition to those
above, or I increase the heating surface still further by placing a set of
tubes in the middle or cylindrical part of the chambers, and lying
horizontal or nearly so, and radially from the axis of the boiler.
In the case of boilers for steam pumps, cranes, or other engines I
expand the lower part of the tube into a fire-box, the construction above
being similar to the aforesaid.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said James Morris in the Great Seal Patent Office on
the 24th December 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JAMES
MORRIS, of Boundary Road, Middlesborough, in the North Riding of the
County of York, send greeting.
WHEREAS. Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-seventh day of June, in the year

page_text: of our Lord One thousand eight hundred and sixty-eight, in the thirty-
second year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto me, the said James Morris, Her special licence that I,
the said James Morris, my executors, administrators, and assigns, or
such others as I, the said James Morris, 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 STEAM BOILERS," upon
the condition (amongst others) that I, the said James Morris, my exe-
cutors 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.
NOW KNOW YE, that I, the said James Morris, 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:-
My Invention has for its object an increase in the power and efficiency
of boilers, particularly for instance those of the vertical class, and is
especially adapted for those that receive the products of combustion
from puddling or heating furnaces, and are known as stack boilers.
I use an inner tube or flue extending from the top to the bottom, and
through which the products of combustion pass. This tube is enlarged
towards the lower part, forming a chamber, which I prefer should be a
conical one, the apex of the cone being downwards, and the base being
made convex upwards. Across this chamber a tube, by preference of
cylindrical form, is fixed, which should be large enough to admit a man's
body, and planted upon this cross tube is a saddle or. chamber forming
part of it, and the shape of which corresponds to the shape of the conical
chamber around and above it. From the inner chamber to the outer
one extend tubes, by preference of a conical or cylindrical form. These
tubes, which may be eight in number (or more or less if desired), are

page_text: Drawings, being understood that I do not claim the constituent parts
per se and apart from the purposes of my said Invention.
In witness whereof, I, the said James Morris, have hereunto set
my hand and seal, this Eighteenth day of December, in the year
of our Lord One thousand eight hundred and sixty-eight.
Witness,
JEREMIAH HEAD,
Iron Manufacturer,
