IMPROVEMENTS IN STEAM ENGINE BOILERS
Year: 1852

page_text: LETTERS PATENT to Joseph Barrans, of Queen's Road, Peckham,
in the County of Surrey, for the Invention of "IMPROVEMENTS IN
STEAM ENGINE BOILERS."
Sealed the 12th January 1853, and dated the 1st October 1852.
PROVISIONAL SPECIFICATION left by the said Joseph Barrans at
the office of the Commissioners of Patents, with his petition, on the
1st October 1852.
I, JOSEPH BARRANS, of Queen's Road, Peckham, in the County of
Surrey, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN STEAM ENGINE BOILERS " to be as follows:
This Invention consists of applying cup-formed vessels, opening into
the fire-box, so as to extend or increase the heating surface, such cups
being either fixed only to the inner plates of the fire-box, or to the inner
and outer ones, as to act as stays, as well as means of increasing
the heating surface.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent
filed by the said Joseph Barrans, in the Great Seal Patent
Office, on the 31st March 1853.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
JOSEPH BARRANS, of Queen's Road, Peckham, in the County of Surrey,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the First day of October in the year of
our Lord One thousand eight hundred and fifty-two, in the sixteenth
year of Her reign, did for Herself, Her heirs and successors, give and
grant unto me, the said Joseph Barrans, Her special licence that I, the
said Joseph Barrans, my executors, administrators, and assigns, or such
others as I, the said Joseph Barrans, 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 ENGINE BOILERS,"
upon the condition (amongst others) that I, the said Joseph Barrans, 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 Joseph Barrans, do hereby declare
the nature of the 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 (that is to say):
This Invention consists of applying cup-formed vessels, opening into
the fire-box, so as to extend or increase the heating surface, such cups
being either fixed only to the inner plates of the fire-box, or to the inner
and outer ones, so as to act as stays as well as means of increasing the
heating surface; and in order that my Invention may be most fully

DESCRIPTION OF THE DRAWING.
..
Figure 1, shows a longitudinal section of part of a steam boiler
having my Improvements applied thereto; Figure 2, is a transverse
section through the fire-box of the boiler; Figure 3, is a horizontal
section thereof; Figure 4, shows a horizontal section of part of the
fire-box, showing the parts half size.
In this arrangement, the cups a, a, form part of the inner plate of
the fire-box only, and the inner and outer plates are connected by stays b.
In Figure 5, the cups a, a, are fixed into the inner plate c, of the
fire-box, as shown, and it will be evident that by thus using a number
of cups, the heating surface of the fire-box exposed to the water in the
boiler will be greatly increased.
In this arrangement, one of the cup-formed vessels is shown fixed so
as to form a stay for the two plates, the inner and the outer one, and is
fixed to the inner plate c, by driving a short ring or tube into it, so as
to expand it into the hole in the plate c.
The cup is formed with a projection, by which it is fixed to the outer
plate d, by rivetting, as shown, and one of the cups are shown to be
fixed by rivetting at e, and another by screw and rivet at f.
I would, however, remark, that I do not confine myself to the modes
of fixing the cup-formed vessels to the plates, whether by screws, rivets
and wedges, or otherwise, as the same may be varied.
The best means I am acquainted with of constructing this plate, with
its cupped recesses, is to cast it of copper or other suitable metal, and
in order to close the grain of the cast metal, to subject it to pressure
between dies.
Having thus described the nature of my said Invention, and the
manner of performing the same, I would have it understood, that I do
not confine myself to the details as herein shown and described, as the
same may be varied without departing from my Invention.

boilers, as herein described.
In witness whereof, I, the said Joseph Barrans, have hereunto set
my hand and scal, this Twenty-ninth day of March in the year
of our Lord One thousand cight hundred and fifty-three.
JOSEPH BARRANS. (L.S.)
Witness, J. G. TONGUE.
