IMPROVEMENTS IN STEAM BOILERS AND IN THE SETTING THEREOF
Year: 1869

page_text: LETTERS PATENT to Henry Cockey and Francis Christopher Cockey,
of Frome Selwood, in the County of Somerset, for the Invention
of "IMPROVEMENTS IN STEAM BOILERS AND IN THE SETTING THEREOF."
Scaled the 7th June 1870, and dated the 11th December 1869..
PROVISIONAL SPECIFICATION left by the said Henry Cockey and
Francis Christopher Cockey at the Office of the Commissioners of
Patents, with their Petition, on the 11th December 1869.
We, HENRY COCKEY and FRANCIS CHRISTOPHER COCKEY, of Frome
Selwood, in the County of Somerset, do hereby declare the nature of,
the said Invention for "IMPROVEMENTS IN STEAM BOILERS AND IN THE
SETTING THEREOF," to be as follows:-
This Invention relates to an improved method of preventing the heat
from boiler fires passing off too quickly into. the chimney without im-
parting to the water a greater amount of heat than in boilers of the
ordinary construction, and thereby greatly decreasing the consumption of
fuel and reducing the quantity of smoke.
The method we adopt for retaining the heat is by fixing to the boiler
what we call "heat conducting plates." If the boiler be cylindrical
the plates are fixed in pairs on the exterior of each side of the boiler

page_text: alternating with single plates attached to the bottom thereof, the latter
being in some cases used also as bearers or saddles for the boiler to rest
In tube boilers we also place conducting plates in the tubes. The
upper plates are fitted and bolted close to the top of the tubes, and
between these top plates intermediate plates are placed on the bottom of
the tubes, but are not fixed thereto and can therefore be easily removed
for the purpose of cleaning out the same. The effect of using these plates
is to divert the heat from passing in a straight course to the chimney
and compel it to assume a zig-zag direction, whereby a much greater
amount of heat is imparted to the water than would otherwise be the
case.
The tubes may be fitted with plates as above described without the
exterior plates mentioned; and although the exterior plates are
described as fixed to the boiler it is not imperative that they should be
made fixtures, as they may be placed in position without any close
attachment thereto being made.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Henry Cockey and Francis Christopher Cockey in
the Great Seal Patent Office on the 10th June 1870.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, HENRY
COCKEY and FRANCIS CHRISTOPHER COCKEY, of Frome Selwood, in tho
County of Somerset, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Eleventh day of December, in the year
of our Lord One thousand eight hundred and sixty-nine, in the thirty-
third year of Her reign, did, for Herself, Her heirs and successors, give
and grant unto us, the said Henry Cockey and Francis Christopher
Cockey, Her special licence that we, the said Henry Cockey and Francis
Christopher Cockey, our executors, administrators, and assigns, or such
others as we, the said Henry Cockey and Francis Christopher Cockey,
our exccutors, 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 "Iм-

page_text: PROVEMENTS IN STEAM BOILERS AND IN THE SETTING THEREOF," upon the con-
dition (amongst others) that we, the said Henry Cockey and Francis
Christopher Cockey, our executors or administrators, by an instrument
in writing under our, 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 we, the said Henry Cockey and Francis
Christopher Cockey, 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, reference
being had to the accompanying Drawing, and to the letters marked
thereon, that is to say :-
This Invention relates to an improved method of preventing the heat
from boiler fires passing off too quickly into the chimney without
imparting to the water a greater amount of such hoat than in boilers of
the ordinary construction, and thereby greatly decreasing the con-
sumption of fuel and reducing the quantity of smoke.
The method we adopt for retaining the heat is by fixing to the boiler
what we call "heat conducting plates." If the boiler be cylindrical the
plates are fixed in pairs on the exterior of cach side of the boiler,
alternating with single plates attached to the bottom thereof, the latter
being in some cases used also as bearers or saddles for the boiler to rest
on. In tube boilers we also place conducting plates in the tubes. The
upper plates are fitted and bolted close to the top of the tubes, and
between these top plates intermediate plates are placed on the bottom
of the tubes, but are not fixed thereto, and can therefore be easily
removed for the purpose of cleaning out the same.
In order that the foregoing may be more easily understood Drawings
are attached hereto, of which the following is a description :-
Fig. 1 is a longitudinal section in the direction of the line D, D, Fig. 2
Fig. 2 is a transverse section through A, A, Fig. 1; Fig. 3 is a trans-
verse section through B, B, Fig. 1; Fig. 4 is a transverse section through
C, C, Fig. 1. E, F, G, Fig. 1, are the exterior "heat conducting plates"
before mentioned, and H, I, J, K, L, M, N, O, and P, are the heat con-
ducting plates inserted within the tube when this Invention is applied
to tube boilers.

page_text: In the Drawing the plates I, K, M, and O are not shown as fixtures,
but may be removed for the purpose of cleaning out the tube and
replaced.
The effect of this Invention is that the heat generated from the fire Q
Fig. 1, is diverted from passing in a straight course and compelled to
assume a somewhat tortuous direction, as indicated by the arrows on
the Drawing, whereby a much greater amount of heat is imparted to
the water than would be but for the intervention of the plates, as
before described.
The tubes may be fitted with plates as above described without
the exterior plates mentioned. And although the exterior plates are
described as fixed to the boiler it is not imperative that they should be
made fixtures, as they may be placed in position without any close
attachment thereto being made.
The Invention is not confined to cylindrical boilers, or to tube boilers,
but may be applied to other and various forms of boilers.
Having now described and particularly set forth the nature of this
Invention, and the manner in which the same is or may be used or
carried into effect, we would observe in conclusion that we do not confine
or restrict ourselves to the preciso details or arrangements which we have
described or referred to, as variations may be made therefrom without
deviating from the principles or main features of this Invention; but
what we consider to be novel and original, and therefore claim as the
Invention secured to us by the herein-before in part recited Letters
Patent is, the construction of steam boilers and the setting thereof
substantially as hercin described.
In witness whereof, wc, the said Henry Cockey and Francis
Christopher Cockey, have hereunto set our hands and scals,
this
day of June, in the year of our Lord One thou-
sand eight hundred and seventy.
HENRY COCKEY.
