Year: 1864

page_text: LETTERS PATENT to John Cookson, of Bradford, in the County of York,
Plumber and Gasfitter, for the Invention of "IMPROVEMENTS IN APPA-
RATUS AND SELF-ACTING VALVES IN CONNECTION WITH KITCHEN BOILERS FOR
HEATING WATER FOR BATHS, WASH BASINS, AND SIMILAR PURPOSES."
Sealed the 20th October 1864, and dated the 28th April 1864.
PROVISIONAL SPECIFICATION left by the said John Cookson at the
Office of the Commissioners of Patents, with his Petition, on the 28th
April 1864.
I, JOHN COOKSON, of Bradford, in the County of York, Plumber and
Gasfitter, do hereby declare the nature of the said Invention for "IMPROVE
MENTS IN APPARATUS AND SELF-ACTING VALVES IN CONNECTION WITH KITCHEN
BOILERS FOR HEATING WATER FOR BATHS, WASH BASINS, AND SIMILAR PURPOSES,"
to be as follows:-
The object of this Invention is to render such apparatus self-acting in
obtaining a supply of water, during frost or other obstruction, in the high-
pressure cistern, and to prevent explosion or stoppage of proper working
thereof; and the improvements consist in combining or connecting a high-
pressure cistern and a low-pressure cistern with the boiler in such manner
that when a stoppage of supply from the high-pressure cistern, and cou-
sequently in the circulating pipes occurs, a valve will be opened to the
low-pressure cistern, and also an escape valve for surplus steam will be
opened. This is effected by constructing, arranging, and applying a spindle
valve to the supply pipe of the low-pressure cistern with its spindle upwards
and a feat ball attached thereto, which will be lifted so as to close the valve
whe. the water rises, and lowered so as to open it when the water lowers in

page_text: the cistern. Also there is a pipe applied to the boiler with a similar valve
placed therein, which will open when the high-pressure cistern ceases to act,
so as to allow the escape of steam from the boiler up the chimney, and which
will be closed again by the high-pressure supply when in action. This con-
struction and arrangement of valve and float ball is applicable to other similar
DURDOSES
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said John Cookson in the Great Seal Patent Office on the
25th October 1864.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
COOKSON, of Bradford, in the County of York, Plumber & Gasfitter, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-eighth day of April, in the year of our Lord
One thousand eight hundred and sixty-four, in the twenty-seventh year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto I,
the said John Cookson, Her special licence that I, the said John Cookson;
my executors, administrators, and assigns, or such others as I, the said John
Cookson, 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
APPARATUS AND SELF-ACTING VALVES IN CONNECTION WITH KITCHEN BOILERS FOR
HEATING WATER FOR BATHS, WASH BASINS, AND SIMILAR PURPOSES," upon the
condition (amongst others) that I, the said John Cookson, my executors 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 John Cookson, do hereby declare the
nature of my said Invention, and in what manner the same is to be per-
formed, to be particularly described, and ascertained-in and by the following
statement (that is to say) :-

page_text: The object of this-Invention is to render such apparatus self-acting, in
obtaining a supply of water, during frost or other obstruction, in the high-
pressure cistern; and to prevent explosion or stoppage of proper working
thereof, and the improvements consist in combining or connecting a high-
pressure cistern and a low-pressure- cistern with the boiler in such manner
that when a stoppage of supply from. the high-pressure. cistern, and icon-
sequently in the circulating pipes occurs, a valve: will be opened to the
low-pressure cistern, and also an escape valve for surplus steam will be
opened. This is effected by constructing, arranging, and applying a spindle
valve to the supply pipe of the low-pressure cistern with its spindles upwards,
and a float ball attached thereto, which will be lifted so as to close the valve
when the water rises; and lowered so as to open it when the water lowers in
the cistern. Also there is a pipe applied to the boiler with a similar valve
placed therein, which will open when the high-pressure. cistern ceases to act
so as to allow the escape of steam from the boiler up the chimney, and which
will be closed again by the high-pressure supply when in action. This con-
struction and arrangement of valve and float ball is applicable to other similar
purposes:
This Invention will be readily understood by reference to the accompanying
Sheet of Drawings, where Fig. 1 represents in section part of a house, shewing
the manner in which my improvements are applied, and the arrangement of
apparatus.
:
A is an ordinary low-pressure cistern placed in any convenient position on a
level with the fireside boiler B. The cistern is provided with a ball tap a for
regulating the supply of water thereto, and a pipe 6 for conducting the water
to the boiler in the usual manner. To the orifice of this pipe is fixed a
spindle valve C, with its spindle upwards, and a float ball c attached thereto,
the size and position of which is adjusted so as that the water as it rises will lift
it and close the valve when at the water level. This valve is shewn in section
on a larger scale at Fig. 2. D is the bigh-pressure cistern. with circulating
pipes E connecting same with the boiler. as, usual, and having branch pipes
attached thereto for supplying hot water to a bath F and slop stone G. To
the boiler there is also attached a pipe H, to which is fixed a valve I of similar
construction to the valve C herein-before described, and a pipe J from thence
into the flue of the chimney; this valve is shewn in section on a larger scale
at Fig. 3.
The action of the apparatus is as follows:-When the high-pressure cistern
is in proper working order the water will rise in the low-pressure cistern until
the valve C becomes closed, and it will also rise in the pipe H until the valve I

page_text: becomes closed; and the high-pressure apparatus will act in the usual manner.
When the high-pressure cistern does not act, or the water ceases to be
supplied therefrom to the boiler, either through frost or other obstruction, so
that the circulation is stopped, and the water in the boiler diminished below
the usual level, the valve C in the low-pressure cistern will be opened and
admit a supply of water therefrom, and the valve I will also open and
allow any steam that may be generated in the boiler to escape into the
flue of the chimney. So soon as the obstruction of the high-pressure supply
is removed the water rises in the boiler and closes the valve C, and also the
valve I, whereby the usual circulation is restored, thus the apparatus is
rendered self-acting in obtaining a supply of water during frost or other
obstruction to the high-pressure supply, and thereby prevent explosions. This
kind or construction of valve and float ball may be applied to the service pipes
of waterworks, as air valves, or other purposes where there is a back action."
Having thus fully described the nature of this my said Invention, and
shewn the manner in which the same is to be performed or put in practical
operation, I would have it understood that I do not confine myself to the
precise details of construction or arrangement of apparatus as herein shewn
and described, as such may be varied or modified without departing from the
main features of the Invention; but what I claim as of my Invention is, -
Firstly, the combining or connecting a high-pressure cistern and a low-
pressure cistern with the same boiler in such manner as to be self-acting for
purposes herein set forth.
"Secondly, the peculiar construction and application of the valves C and I,
for purposes herein described or similar purposes.
In witness whereof, I, the said John Cookson, have hereunto set my
hand and seal, this Twenty-second day of October, One thousand eight
hundred and sixty-four.
Signed, sealed, and delivered by the
within-named John Cookson, in the
presence of
