IMPROVEMENTS IN BALL AND OTHER COCKS AND VALVES
Year: 1857

page_text: LETTERS PATENT to Frederick Warner; of Jewin Crescent, Cripplegate,
for the Invention of "IMPROVEMENTS IN BALL AND OTHER COCKS AND
VALVES."
Sealed the 8th January 1858, and dated the 21st July 1857.
PROVISIONAL SPECIFICATION left by the said Frederick Warner at
the Office of the Commissioners of Patents, with his Petition, on the
21st July 1857.
I, FREDERICK WARNER, of Jewin Crescent, Cripplegate, do hereby declare
the nature of the Invention for "IMPROVEMENTS IN BALL AND OTHER COCKS
AND VALVES," to be as follows:―
This Invention has for its object improvements in ball and other cocks and
valves. For these purposes the barrel or fluid passage is formed with a valve
chamber at its outer end, the outlet for the fluid being formed at the lower
part of such chamber below the valve. The upper part of the chamber is
closed by a cover fixed by screws or other convenient means. To the under
surface of such cover, where the spindle of the valve passes through it, is
formed a projection on which is fixed a flexible cup of leather or other suitable
material, which enters the upper part of the valve, which is formed of a hollow
cylinder closed at the bottom and open at the top. The lower part of the
valve presses on a suitable seat which is around the outlet passage, and it is
preferred that the seat should be of flexible material. The spindle of the valve

page_text: is fixed to the bottom thereof and passes through the cover of the valve
chamber, where it is acted on by the float, lever, or other instrument used for
opening or closing of the valve, according to the purpose to which the cock or
valve is to be applied. The pressure of the fluid acts on the upper surface of
the cupped material, and presses its circumference in contact with the inner
surface of the cylindrical valve, and the cylinder when raised and lowered
moves over the cup, which prevents the fluid passing into the cylinder below
the cup.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Frederick Warner in the Great Seal Patent Office on the
21st January 1858.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, FREDERICK
WARNER, of Jewin Crescent, Cripplegate, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-first day of July, in the year of our Lord
One thousand eight hundred and fifty-seven, in the twenty-first year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
tho said Frederick Warner, Her special licence that I, the said Frederick
Warner, my executors, administrators, and assigns, or such others as I,
the said Frederick Warner, 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 BALL AND OTHER COCKS AND VALVES," upon the condition
(amongst others) that I, the said Frederick Warner, 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 Frederick Warner, do hereby declare
the nature of the 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 thereof, that is to say :-
This Invention has for its object improvements in ball and other cocks and

page_text: valves. For these purposes the barrel or fluid passage is formed with a valve
chamber at its outer end, the outlet for the fluid being formed at the lower
part of such chamber below the valve. The upper part of the chamber is
closed by a cover fixed by screws or other convenient means. To the under
surface of such cover, where the spindle of the valve passes through it, is
formed a projection on which is fixed a flexible cup of leather or other suitable
material, which enters the upper part of the valve, which is formed of a hollow
cylinder closed at the bottom and open at the top. The lower part of the
valve presses on a suitable seat which is around the outlet passage; and it is
preferred that the seat should be of flexible material. The spindle of the valve
is fixed to the bottom thereof, and passes through the cover of the valve
chamber, where it is acted on by the float, lever, or other instrument used for
opening or closing of the valve, according to the purpose to which the cock or
valve is to be applied. The pressure of the fluid acts on the upper surface of
the cupped material, and presses its circumference in contact with the inner
Surface of the cylindrical valve, and the cylinder when raised and lowered
moves over the cup, which prevents the fluid passing into the cylinder below
the cup.
Ilaving thus stated the nature of my said Invention, I will proceed more
fully to describe the manner of performing the same.
DESCRIPTION OF THE DRAWING.
Figure 1 shows an external view of a ball cock or valve constructed
according to iny Invention; Figure 2 shows a vertical section thereof. a, a,
is the body or barrel of the cock or valve; bis the lever to which the ball or
float is attached. When a cock or valve made according to my Invention is
intended for other uses, the ball and lever are dispensed with, and the valve
rod or spindle is moved by any other suitable handle or lever, as is well under-
stood in the manufacture of cocks and valves. d is a cylinder which is open
at the top and closed at the bottom. The under surface of the bottom of the
cylinder & closes the outlet passage, and this under surface or the seat, or botli,
may be coated with flexible elastic material, or the surfaces may be ground or
fitted, as is well understood by manufacturers of cocks and valves. c is the top
or cover of the cock or valve, to the under side of which is fixed a cupped
leather e, or a cup of any suitable flexible material. The projection on the
under side of the cover c to which the cup is attached, is fixed to the cover
fluid-tight by being screwed thereto with a washer between; or the projection
forms part of the cover c, and such cover is fixed by screw or otherwise, and
made fluid-tight by a washer. f is the valve rod or spindle which at its lower

page_text: end is fixed to the cylinder d. By this arrangement it will be seen that the
cylinder when raised or lowered moves over the cupped leather or material e.
The lower end of the valve rod or spindle is perforated longitudinally, and
there is a small transverse hole so that air may enter below the cupped
leather.
Having thus described the nature of my said Invention, and the manner
of performing the same, I would have it understood that I make no claim
to any of the parts separately; but what I claim is the combination herein
described.
In witness whercof, I, the said Frederick Warner, have hereunto set
my hand and seal, this Twentieth day of January, in the year of our
Lord One thousand eight hundred and fifty-eight.
Witness,
