Office of the Commissioners of Patents, with his Petition, on the 9th
June 1855.

I, THOMAS BRIGHT, Ironfounder, of Carmarthen, South Wales, do hereby
declare the nature of the Invention for "IMPROVEMENTS. IN APPARATUS FOR
THE PREVENTION OF WASTE IN WATER OR OTHER FLUID SUPPLIES." to be as
follows
This Invention has for its object improvements in apparatus for preventing
of waste in water, and other fluid supplies.. For this purpose a close vessel
having a suitable air valve is connected to the supply pipe; the supply pipe has
also a two-way cock applied to it, by which either, the inlet to or the outlet
from the intermediate vessel will-be shut when the other is

by the said Thomas Bright in the Great Seal Patent Office on the
7th December 1855.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
BRIGHT, Ironfounder, of Carmarthen, South Wales, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Ninth day of June, in the year of our Lord
One thousand eight hundred and fifty-five, in the eighteenth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Thomas Bright, Her special licence that I, the said Thomas Bright,
my executors, administrators, and assigns, or such others as I, the said Thomas
Bright, 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 APPA-
RATUS FOR THE PREVENTION OF WASTE IN WATER OR OTHER FLUID SUPPLIES," upon
the condition (amongst others) that I, the said Thomas Bright, by an instru-
ment 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 Thomas Bright, 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) :—
The object specially comprehended in this Invention is the prevention of
waste in water and other fluid supplies, arising from the draught or service
cock being left open. I place a close vessel furnished with an air valve, when
necessary, in connection with the supply pipe, a double-action bibb cock being
placed upon the said pipe previous to its entrance into the said vessel, which
cock is so constructed and arranged that the inlet passage or supply to the
closed vessel will always be closed when the outlet passage or draught is open,
and the outlet passage or draught will always be closed when the inlet passage
or supply is open. By this means no more water or other fluid can at any
time be wasted, should the draught passage be left open, than the quantity
contained in the aforesaid closed vessel.

page_text: And in order that my said Invention may be fully understood and readily
carried into effect, I will proceed to describe the Drawing hereunto annexed.
DESCRIPTION OF THE DRAWING.
Figure 1 is a longitudinal section of the apparatus. A is the supply pipe,
on the end of which is placed the closed vessel B. There is an air passage
formed on the top of the vessel B, which is closed by the valve D when the
water raises the ball float C. E is the cover of the air valve; F is a two-
way cock on the supply pipe, by which the water is drawn off for use.
Figure 2 shows a longitudinal section of the cock when in position for
drawing water.
Having thus described the nature of my Invention, and the manner of
performing the same, I would have it understood that I do not confine myself
to the exact details described; but I claim the arrangement for the admission
and discharge of fluids into and from an intermediate closed vessel by means
of a double-action cock, so arranged that the inlet passage or supply will
always be closed when the outlet passage or draught is open, and the outlet
passage or draught will always be closed when the inlet passage or supply
is open.
In witness whereof, I, the said Thomas Bright, have hereunto set my
hand and seal, this Fifth day of December, in the year of our Lord
One thousand eight hundred and fifty-five.
