Year: 1866

page_text: LETTERS PATENT to John Dickinson, the younger, of the City of York,
Plumber, for the Invention of "IMPROVEMENTS IN, COCKS OR TAPS FOR HIGH-
PRESSURE HOT AND COLD WATER, AND FOR KITCHEN, RANGES,"
Sealed the 16th October 1866, and dated the 17th April 1866
PROVISIONAL SPECIFICATION left by the said John Dickinson at the
Office of the Commissioners of Patents, with his Petition; on the
17th April 1866.
I, JOHN DICKINSON, the younger, of the City of York, Plumber, do.
hereby declare the nature of the said Invention for "IMPROVEMENTS IN COCKS
OR TAPS POR HIGH-PRESSURE HOT AND COLD WATER, AND FOR KITCHEN RANGES,"
to be as follows:
This Invention relates to certain improvements in the construction of cocks
or taps applicable to high-pressure hot and cold water, and to kitchen ranges.
at the side of the fire. The exterior of the tap is similar to those in ordinary
use, but the handle works with a screw thread cut on the stem, which passes
through a stuffing box set between two flanges on the upper part of the tap.
The inlet is made with a boss or collar, so that the tap may be applied to an
iron pipe or a leaden pipe. The valve is applied at the bottom of the tap; it is
of brass and ground to fit the valve seat, and made with a screw bottom, so as
to permit of easy access to the valve for the purpose of repair without the
necessity of disconnecting the tap from the pipe. By means of the screw
handle the opening of the valve may be regulated to the greatest nicety, and

page_text: when subject to high pressure the valve is entirely under the control of the
screw and cannot be forced further open by the pressure, neither can any
escape or leakage occur between the screw and flanges by reason of the
intermediate stuffing box.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said John Dickinson in the Great Seal Patent Office on the
17th October 1866.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
DICKINSON, the younger, of the City of York, Plumber, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Seventeenth day of April, in the year of our Lord
One thousand eight hundred and sixty-six, in the twenty-ninth year of
Пer reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said John Dickinson, Her special licence that I, the said John
Dickinson, my executors, administrators, and assigns, or such others as I,
the said John Dickinson, my executors, administrators, and assigns, should
at any time agree with, and no others, from time to time and at all
tjines 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 FOR HIGH-PRESSURE HOT AND COLD WATER,
AND FOR KITCHEN RANGES," upon the condition (amongst others) that 1, tho
said John Dickinson, 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 Dickinson, do hereby declare the
nature of my said Invention, and in what manner the same is to be per-
forined, to be particularly described and ascertained in and by the following
statement:-
This Invention relates to certain improvements in the construction of cocks
or taps applicable to high-pressure hot and cold water, and to kitchen ranges at
the side of the fire. The exterior of the tap is similar to those in ordinary use,
but the handle works with a screw thread cut on the stem which passes through

page_text: a stuffing box set between two flanges on the upper part of the tap. The inlet
is made with a boss or collar, so that the tap may be applied to an iron pipe or
a leaden pipe. The valve is applied at the bottom of the tap; it is of brass
and ground to fit the valve seat, and made with a screw bottom, so as to permit
of easy access to the valve for the purpose of repair without the necessity of
disconnecting the tap from the pipe. By means of the screw handle the opening
of the valve may be regulated to the greatest nicety, and when subject to high
pressure the valve is entirely under the control of the screw, and cannot be
forced further open by the pressure, neither can any escape or leakage occur
between the screw and flanges by reason of the intermediate stuffing box.
The Drawing annexed represents a longitudinal section of the tap. a is the
handle attached to the screw-threaded stem 6 passing through the stuffing
box c, set between the flanges d, d; e is the inlet to the tap provided with
the collar f; g is the ground valve, brass and brass, attached to the vertical
spindle h; and i is the valve seat screwed into the bottom of the tap.
Having now described the nature of my said Invention, and the manner in
which the same is to be performed, I would remark that I do not limit
myself to the precise details, dimensions, or configuration of parts I have
expressed and shewn, as the same may obviously be varied or modified with-
out departing from the principles of the Invention; but what I claim and
desire to be secured to me by the herein in part recited Letters Patent are,
the general arrangement and combination of parts constituting an improved
tap for high-pressure hot and cold water, and for kitchen ranges at the side
of the fire, substantially as herein specified and shewn.
In witness whereof, I, the said John Dickinson, have hereunto set my
hand and seal, this Thirteenth day of October, in the year of our Lord
One thousand eight hundred and sixty-six.
JOHN DICKINSON, JUNIOR. (L.S.)
