Year: 1862

page_text: LETTERS PATENT to John Endean, Lock's Fields, Walworth, in the
County of Surrey, Brass Founder, for the Invention of "IMPROVEMENTS
IN COCKS, TAPS, AND VALVES."
Sealed the 17th October 1862, and dated the 24th April 1862.
PROVISIONAL SPECIFICATION left by the said John Endean at the
Office of the Commissioners of Patents, with his Petition, on the 24th
April 1862.
I, JOHN ENDEAN, of Lock's Fields, Walworth, in the County of Surrey,
5. Brass Founder, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN COCKS, TAPS, AND VALVES," to be as follows:-
At the proper point of a pipe, or duct pipes, or ducts, I have an enlarged
part or chamber or valve box with a cone or conical portion with apertures
communicating with the pipe or duct pipes, or ducts, and on this cone I fit a
hollow cone or conoid corresponding with the first-mentioned cone, and also
having apertures corresponding with the apertures therein, the movement of
which hollow cone will cause the cock, tap, or valve to open and shut as
required, all the parts being made and fitted together in due and workman-like
manner.

page_text: SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Endean in the Great Seal Patent Office on the

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
ENDEAN, of Salisbury Place, Lock's Fields, Walworth, in the County of
Surrey, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-fourth day of April, in the year of our Lord
One thousand eight hundred and sixty-two, in the twenty-fifth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me
the said John Endean, Her special- licence that I, the said John Endean,
my executors, administrators, and assigns, or such others as I, the said
John Endean, my executors, administrators, and assigns, should at any
time agree with, and no others, from time to time and at all times there-
after 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, TAPS, AND VALVES," upon the condition (amongst others) that I,
the said John Endean, 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 Endenn, do hereby declare
the nature of my said Invention, and in what manner the same is to bo
performed, to be particularly described and ascertained in and by the following
statement:
"
(No. 1.) The nature of this Invention consists in this :-A duct or ducts
is or are formed with a cock, tap, or valve shank, as it is termed, having a
chamber or valve box provided with a solid or partially solid enlargement of
the said duct or ducts of conical or conoidal form with the requisite apertures
therein, and upon this conical or conoidal part is fitted a hollow cone or conoid
correspondent thereto, provided also with apertures to correspond with the
apertures communicating with the ducts and ways adopted, so that the steam,
gas, water, or fluid will enter the valve box or chamber, pass over or against
the said hollow cone or conoid, and out at the outlet or outlets. This hollow
cone or conoid being provided with a stem, spindle, or handle passing through

page_text: the chamber or valve box aforesaid, whereby the hollow cone or conoid may bo
turned so as to bring the apertures therein upon, to, or away from the apertures
in the aforesaid enlargement of the duct or ducts, and thus open and shut tlie
same, as desired, and as hereafter explained I so arrange the apertures that
the inlet shall never be closed, and hence the hollow cone or conoid shall
always be kept held. to its seat with an equal pressure on its entire surface.
(No. II.) Having thus described the nature of the said Invention, I will
now proceed to describe in what manner the same is to be performed, wherein
I shall refer to the accompanying Drawing by the words, figures, and letters
11
the chamber or valve box aforesaid, whereby the hollow cone or conoid may bo
turned so as to bring the apertures therein upon, to, or away from the apertures
in the aforesaid enlargement of the duct or ducts, and thus open and shut thie
same, as desired, and as hereafter explained I so arrange the apertures that
the inlet shall never be closed, and hence the hollow cone or conoid shall
always be kept held to its seat with an equal pressure on its entire surface.
(No. II.) Having thus described the nature of the said Invention, I will
now proceed to describe in what manner the same is to be performed, wherein
I shall refer to the accompanying Drawing by the words, figures, and letters
following, that is to say
DESCRIPTION OF THE DRAWINGS.
Fig. 1 is an external view; Fig. 2, longitudinal vertical section. A, A;
the duct or ducts of the shank; B' inlet, and B outlet apertures formed,
B' at the edge of, and B in the said conical enlargement of the said shank; C,
the solid part of said enlargement, separating the duct or ducts A, A, thus
forming the inlet and outlet D, D, the hollow cone or conoid having apertures
therein, as shewn at D, D. E denotes the spindle for working the cock,
tap, or valve, which spindle should be in two parts, as shewn detachable from
each other, the lower one being fixed to or forming part of the said hollow
cone or conoid, and the other, which passes through the top of the outer casing
of the chamber or valve box (F, F,) being applied thereto by having a
square socket at its lower end fitting on the square head of the fixed part of
the spindle aforesaid, which arrangement will allow for any inequality in
packing the spindle, so that the valve shall not be turned aside by the
spindle being forced out of the perpendicular. Around the detachable part
of the spindle is a packing ring f, f, for packing the same against a shoulder
provided for that purpose, as shewn.
The other details will be understood by inspection of the Drawings without
particular description; I may mention, however, that (g, 9,) is a screw nut
screwed into the end of the upper spindle (E), and preventing the same
from rising too far out of its place. (h, h,) is a screw cap screwed on to the
top of the valve box or chamber F, F, aforesaid; through the screw cap h the
upper part of the spindle passes.
It will be obvious to the practical man that these details may be varied for
two-way or three-way cocks, and so forth; and also that these improvements
may be adopted for cocks and valves for gas, steam, water, air, and other
purposes. The water, steam, gas, or fluid will be allowed at all times freely.
to come in by the inlet aperture, and thus press the hollow cone tightly upon

page_text: or against the enlargement aforesaid, but if this pressure should in any case
be deemed insufficient, a coiled spring can be applied round the spindle
at X, X.
(No. III.) Having now particularly described and ascertained the nature
of the said Invention, and in what manner the same is to be performed, I
hereby declare that I claim the said Invention as the same is set forth in the
outset (at the part marked No. I. in the words extending to part marked
No. II.).of this my Specification thereof.
In witness whereof, I, the said John Endean, have hereunto set my
hand and seal, this Twenty-fourth day of October, in the year of
our Lord One thousand eight hundred and sixty-two.
JOHN ENDEAN.. (L.S.)
