Year: 1858

page_text: LETTERS PATENT to Frederick Warner, of Jewin Street, in the City of
London, John Derbyshire, of Longton, in the County of Stafford, and
Alexander Mann, of Little Britain, in the City of London, for the Inven-
tion of "AN IMPROVEMENT IN THE MANUFACTURE OF COCKS OR TAPS."
Sealed the 31st May 1859, and dated the 1st December 1858.
PROVISIONAL SPECIFICATION left by the said Frederick Warner, John
Derbyshire, and Alexander Mann at the Office of the Commissioners of
Patents, with their Petition, on the 1st December 1858.
"We, FREDERICK WARNER, of Jewin Street, in the City of London, JOHN
DERBYSHIRE, of Longton, in the County of Stafford, and ALEXANDER MANN, of
Little Britain, in the City of London, do hereby declare the nature of the
Invention for." AN IMPROVEMENT IN THE MANUFACTURE OF COCKS OR TAPS," to be:
as follows:-
This Invention has for its object an improvement in the manufacture of
cocks or taps. For this purpose the valve is suspended to or formed on the
end of a tube of india-rubber (by preference vulcanized india-rubber), the
other end of the india-rubber is flanched so as to attach it to the body of the
cock or tap. The spindle or screw, by. which the valve is pressed. on its seat,
passes into the tube of india-rubber, which is shorter than the distance between
the valve seat and point of connection of the flanch of the tube of india-
rubber, so that the tube will require to be extended in length in order to close
the valve, and consequently the india-rubber tube will, when released, aid in
lifting the valve from its seat.

TO ALL TO WHOM THESE PRESENTS SHALL COME, we, FREDERICK
WARNER, of Jewin Street, in the City of London, JOHN DERBYSHIRE, of Long-
ton, in the County of Stafford, and ALEXANDER MANN, of Little Britain, in the
City of London, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the First day of December, in the year of our Lord
One thousand eight hundred and fifty-eight, in the twenty-second year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us, the
said Frederick Warner, John Derbyshire, and Alexander Mann, Her special
licence that we, the said Frederick Warner, John Derbyshire, and Alexander
Mann, our executors, administrators, and assigns, or such others as we, the said
Frederick Warner, John Derbyshire, and Alexander Mann, our 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 "AN IMPROVEMENT IN THE MANUFACTURE OF COCKS OR TAPS,"
upon the condition (amongst others) that we, the said Frederick Warner, John
Derbyshire, and Alexander Mann, our executors or administrators, by an
instrument in writing under our or their hands and seals, or under the hand
and seal of one of us or them, 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, on behalf of myself
and the said John Derbyshire, and Alexander Maun, 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 an improvement in the manufacture of
cocks or taps. For this purpose the valve is suspended to or formed on the
end of a tube of india-rubber (by preference vulcanized india-rubber), the
other end of the india-rubber is flanched so as to attach it to the body of the
cock or tap. The spindle or screw, by which the valve is pressed on its seat,
passes into the tube of india-rubber which is shorter than the distance between

page_text: the valve seat and point of connection of the flanch of the tube of india-rubber,
so that the tube will require to be extended in length in order to close the
valve, and consequently the india-rubber tube will, when released, aid in lifting
the valve from its seat.
Having thus stated the nature of our Invention, we will proceed more fully
to describe the manner of performing the same.
DESCRIPTION OF THE DRAWING.
Figure 1 is a longitudinal section of a cock or tap having our improve-
ments applied thereto; Figure 2 shews a side view, a plan, and a section of
the india-rubber tube used in constructing the valve or plug. a, a, is the
lower part or closed end of the tube of india-rubber which comes to the seat
or passage for the fluid; b is the tube, and c is the flanch by which it is fixed
fluid-tight, such flanch being fixed between the cover and the upper end of
the cylinder or chamber of the cock or tap. The length of the tube b is to
be shorter than the distance between the seat or fluid passage and the end of
the cylinder or chamber d, in order that the tube a, b, may, if required, be
elongated by the pressure of the internal valve or plug e. The internal valve
or plug e is in the arrangement shown moved by a screw, but this may be
varied, canvass or other woven fabric may be used to give strength to the
lower part and closed end of the tube, and such may also be the case in
regard to the flanch, sufficient length of the tube being left elastic to admit of
its being stretched to the extent required.
Having thus described the nature of our Invention, and the manner of
performing the same, we would have it understood that we do not confine
ourselves to the shape or form of the tap or cock shewn ; but what we claim is
the construction of cocks or taps with india-rubber tubes a, b, c, as herein
described.
In witness whereof, I, the said Frederick Warner, have hereunto set
my hand and seal, this First day of June, in the year of our Lord
One thousand eight hundred and fifty-nine.
FRED" WARNER. (L.S.)
