Year: 1875

page_text: LETTERS PATENT to William Richardson, of Darlington, in the County
of Durham, Horticultural Engineer, for the Invention of "IMPROVE-
MENTS IN THE CONSTRUCTION OF BOILERS FOR HEATING WATER FOR WARMING
BUILDINGS."
Sealed the 2nd June 1876, and dated the 8th December 1875.
PROVISIONAL SPECIFICATION left by the said William Richardson at
the Office of the Commissioners of Patents, with his Petition, on
the 8th December 1875.
I, WILLIAM RICHARDSON, of Darlington, in the County of Durham,
Horticultural Engineer, do hereby declare the nature of the said Inven-
tion for "IMPROVEMENTS IN THE CONSTRUCTION OF BOILERS FOR HEATING WATER
FOR WARMING BUILDINGS," to be as follows:-
This Invention relates to the construction of boilers for heating water
for warming buildings, whereby such operation is performed in a much
simpler and more economical manner than by the boilers hitherto con-
structed.

page_text: According to this Invention a
"saddle "
or water jacket is placed
over the upper part of a horizontal tubular boiler, and connected there-
with in such a manner that the water circulates through both, and the
flames and heated gases instead of passing directly into the chimney, as
in the case of a tubular boiler alone, pass between the upper surfaces
of the tubular boiler and the lower surface of the "saddle," and if desired
they may be conducted through suitable flues placed above the "saddle"
or water jacket, in order to absorb the whole or nearly the whole of
the heat from the flames or gases before they pass into the chimney.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Richardson in the Great Seal Patent Office
on the 8th June 1876.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
RICHARDSON, of Darlington, in the County of Durham, Horticultural
Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Eighth day of December, in the year
of our Lord One thousand eight hundred and seventy-five, in the thirty-
ninth year of Her reign, did, for Horself, Her heirs and successors,
give and grant unto me, the said William Richardson, Her special
licence that I, the said William Richardson, my executors, adminis-
trators, and assigns, or such others as I, the said William Richardson,
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 THE CONSTRUCTION OF BOILERS FOR HEATING WATER FOR
WARMING BUILDINGS," upon the condition (amongst others) that I, the
said William Richardson, my executors or administrators, by an in-
strument in writing under my, or their, or one of their hands and seals,
should particularly describe and ascertain the nature of the said Inven-
tion, 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

page_text: months next and immediately after the date of the said Letters
Patent.
NOW KNOW YE, that I, the said William Richardson, 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, reference being had to the Drawings
hereunto annexed, and to the letters and figures marked thereon, that is
to say :-
My said Invention relates to the construction of boilers for heating
water for warming buildings, whereby such operation is performed in a
more economical manner than by the boilers hitherto constructed.
According to my Invention a saddle or water jacket is placed over a
horizontal tubular boiler, and connected therewith in such a manner
that the water circulates through both, and the fire, in addition to
heating the tubular boiler in which it is held, also directly heats the
internal surface of the saddle or water jacket, and the flames and heated
gases instead of passing directly thence into the chimney as in the case
of a tubular boiler alone, pass through the further end of the boiler, and
are conducted by flues over the whole outer surface of the saddle or
water jacket, by which arrangement the advantages of two separate
boilers, a tubular and a plain saddle boiler, are obtained with only one
fire, thus effecting a considerable saving of fuel.
I will now proceed to refer to the accompanying Drawings, from
which the nature of my said Invention will be more clearly understood.
Figure 1 is a vertical section of a boiler constructed according to my
Invention, taken near and looking towards the front thereof.
Figure 2 is a side elevation, and Figure 3 a vertical section through
the boiler, taken near and looking towards the back thereof, and shewing
the brick setting to the boiler.
The same letters of reference indicate like parts in all the Figures.
A is the fire-space; B, the front end of the tubular boiler; C, the
back of the same; D, the flue; E, tubes or water bars upon which the
fire rests, and through which the return water passes previous to circu-
lating in the upper tubes; F, the upper tubes; G, G, the pipes con-
necting the tubular boiler with the saddle; H, the saddle or water

page_text: jacket; I, flanges or midfeathers forming the flues over the outer surface
of the saddle; J, the said flues, K and L being the return and flow
pipes.
Having thus described and ascertained the nature of my said Inven-
tion, and in what manner the same is to be performed, I would observe
in conclusion that I do not confine myself to the precise details shewn
and described, as these may be varied without departing from the
principles of my said Invention, but what I consider novel and original,
and therefore claim as constituting the Invention secured to me by
the herein-before in part recited Letters Patent is, the combination
and arrangement of a horizontal tubular boiler with a saddle or water
jacket, in the manner and for the purposes herein-before set forth and
described, or any mere modifications thereof.
In witness whereof, I, the said William Richardson, have here-
unto set my hand and seal, this Third day of June, in the
year of our Lord One thousand eight hundred and seventy-six.
Witness,
