IMPROVEMENTS IN COCKS OR TAPS
Year: 1853

page_text: LETTERS PATENT to William Vincent, of 195, Brick Lane, Spital-
fields, in the County of Middlesex, of the firm of Noakes and
Vincent, for the Invention of "IMPROVEMENTS IN COCKS OR TAPS."
PROVISIONAL SPECIFICATION left by the said William Vincent
at the Office of the Commissioners of Patents, with his Petition,
on the 19th January 1853.
S.
J; WILLIAM VINCENT, of 195, Brick Lane, Spitalfields, in the County
of Middlesex, of the firm of Noakes & Vincent, do hereby declare the
nature of the said Invention for "IMPROVEMENTS IN COCKS OR TAPS" to be
as follows:-
This Invention consists of constructing the barrel with a somewhat
conical chamber, into and from which the fluid passes by suitable open-
ings. The face against which the plug works is excentric to the centre
on which the plug turns within the chamber. The plug consists of a
covering surface to the outlet of the cock, and is also excentric to its
axis of motion, by which construction the effect of wear is compensated

filed by the said William Vincent in the Great Seal Patent Office
on the 18th July-1853
TO ALL, TO WHOM THESE PRESENTS SHALL COME, I,
WILLIAM VINCENT, of 195, Brick Lane, Spitalfields, in the County of
Middlesex, of the firm of Noakes and Vincent, send greeting.
...நீ
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Nineteenth day of January, in the year
of our Lord One thousand-eight-hundred-and..fifty-three, in the six-
teenth year of Her reign, did, for Herself, Her heirs and successors,
give and grant unto me, the said William Vincent, Her special licence
that I, the said William Vincent my-executors, administrators, and
assigns, or such others as I, the said William Vincent, 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 COCKS
OR TAPS," upon the condition (amongst others) that I, the said William
Vincent, by an instrument 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 William Vincent, do hereby declare
the nature of the said Invention, and in what manner the same is to be
performed; to be particularly described and ascertained in' and by the
following statement thereof (that is to say):
...
This Invention consists of constructing the barrel with a somewhat'
conical chamber, into and from which the fluid passes by suitable

page_text: openings. The face against which the plug works is excentric to the
centre on which the plug turns within the chamber. The plug con-
sists of a covering surface to the outlet of the cock, and is also excentric
to its axis of motion, by which construction the effect, of wear is compen-
sated for, and the parts, continue effective. The plug only moves in one
direction, and has a stop on it, which coming against a stop in the
interior of the chamber prevents the plug being moved too far. And in-
order that my said Invention may be more fully understood.. and readily
carried into effect, I will proceed to describe the means pursued by me.

DESCRIPTION OF THE DRAWING.
Figure 1, shows an external view of a cock or tap constructed accord-
ing to my Invention; Figure 2, is a vertical section of the same;
Figure 3, is a horizontal section; Figure 4, is a vertical section of the
barrel without the plug; Figure 5, is a plan, the handle of the plug
spindle being removed; the dotted lines show the plug in the position of
being opened; and Figure 6, shows a plan and elevation of the plug and
its spindle separately. In each of these Figures the same letters are used
to indicate similar parts. a, is the barrel which is made suitable for
being fixed by screws at the two ends, but this may be varied. a¹, is a
somewhat conical chamber, within which the plug b, works. The face
a, a, against which the plug b, works in order to close the outlet
passage is excentric to the centre on which the plug turns, and the face
of the plug b, which covers the outlet is excentric to its axis; hence, as
the face a², a², of the chamber a', and the face of the plug, where the
only effect will be, that the plug will
more on its axis to obtain a perfect
necessary before the wear took place.
which is fixed to or forms part of the plug; and a is a stop on the in-
terior of the chamber a¹ of the barrel, and these stops prevent the plug
being moved too far. The spindle of the plug 6, passes through a
stuffing box c, formed in the cover d, of the chamber a', all which will
readily be understood on examining the Drawing.
require to be turned somewhat
closing of the outlet than was
', is a curved projection or stop,
Having thus described the nature of my said Invention, and the
manner of performing the same, I would have it understood that what I

page_text: claim is, the mode herein described of constructing and combining the
parts of cocks and taps.
