IMPROVEMENTS IN THE MANUFACTURE OF HIGH-PRESSURE COCKS."
Year: 1864

page_text: LETTERS PATENT to George Frederick Graham, of No. 1, Upper Gordon
Street, Euston Square, and William Payne, of No. 2, Everett Street,
Brunswick Square, both in the County of Middlesex, for the Invention
of "IMPROVEMENTS IN THE MANUFACTURE OF HIGH-PRESSURE COCKS."
PROVISIONAL SPECIFICATION left by the said George Frederick Graham
and William Payne at the Office of the Commissioners of Patents, with
their Petition, on the 2nd July 1864.
We, GEORGE FREDERICK GRAHAM, of No. 1, Upper Gordon Street, Euston
Square, and WILLIAM PAYNE, of No. 2, Everett Street, Brunswick Square,
both in the County of Middlesex, do hereby declare the nature of the said
Invention for "IMPROVEMENTS IN THE MANUFACTURE OF HIGH-PRESSURE COCKS,"
to be as follows:-
This Invention of improvements in high-pressure cocks of gun metal or
brass, consists of a combination of plug and valve, and is worked by the
ordinary lever handle or key attached to the plug, the valve being raised or
lowered by the revolution of the plug somewhat resembling an eccentric
surface action; by this Invention the whole of the pressure is received direct
on the valve, instead of the barrel of the cock, as is the case with those now
in ordinary use. Should any water or other liquid escape by the valve it
would pass into a chamber over the plug, leakage being thereby effectually
prevented.
This Invention will be found applicable to ball, bib, or stop cocks, and can
be applied for the purposes of hot or cold water or other liquids.

and of an Order of the Lord Chancellor by the said George Frederick
Graham and William Payne in the Great Seal Patent Office on the 24th
January 1865.
TO ALL TO WHOM THESE PRESENTS SHALL COME, W, GEORGE
FREDERICK GRAHAM, of No. 1, Upper Gordon Street, Euston Square, and
WILLIAM PAYNE, of No. 2, Everett Street, Brunswick Square, both in the
County of Middlesex, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Second day of July, in the year of our Lord One
thousand eight hundred and sixty-four, in the twenty-eighth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto us, the said
George Frederick Graham and William Payne, Her special licence that we,
the said George Frederick Graham and William Payne, our executors,
administrators, and assigns, or such others as we, the said George Frederick
Graham and William Payne, 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 "Iж-
PROVEMENTS IN THE MANUFACTURE OF HIGH-PRESSURE COCKS," upon the condition
(amongst others) that we, the said George Frederick Graham and William
Payne, our executors or administrators, by an instrument in writing under
our, 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 we, the said George Frederick Graham and
William Payne, do hereby declare the nature of our said Invention, and
in what manner the same is to be performed, to be particularly described
and ascertained in and by the following statement, reference being had to the
annexed Drawings and to the letters and figures marked thereon, that is
to say:-
This Invention of improvements in high-pressure taps or cocks consists of a
combination of valve and cock. We make a single barrel high-pressure cock
or tap of gun metal, or other suitable material, and in the barrel of this tap is
formed a receptacle or chamber in which a valve is placed, which is actuated

page_text: by means of an eccentric or incline on the plug of the cock being worked or
turned by the ordinary lever handle key. The whole of the pressure caused
by the liquid being received by the valve instead of the plug, as in the case
with cocks now in use, any liquid escaping past the valve is received into
the barrel between the valve and plug, leakage being thereby effectually
prevented.
This Invention will be found applicable to bib or stop cocks and can be
used for hot or cold water purposes.
And in order that our Invention may be more readily understood we will
proceed to describe the same by reference to the annexed Drawings where
Fig. 1 represents side elevation of a high-pressure water tap, full size; Fig. 2
section of same, and Fig. 3 back elevation; corresponding letters refer to
similar parts in Figures 1, 2, and 3.
a, a, shews the valve b, the eccentric or incline worked or actuated in the
plug by the lever handle c, to raise the valve a; da cap socketted and
screwed to form a guide to valve a, and which is capable of being easily
removed; the part indicated by the arrow shews the inlet for water; e, the
outlet or nosil. In the sectional view, Fig. 2, the tap is shewn closed, the
dotted lines indicating the position of the valve a and lever handle c when the
tap is open. It will be seen that the liquid entering at the inlet f, is received
by the valve a, any liquid escaping past this valve being received in the barrel
as before described.
Having now described the nature and object of this Invention, we declare
that what we claim and desire to be secured by the herein-before recited
Letters Patent is, the improvements in the manufacture of high-pressure cocks
or taps substantially as herein-before described and illustrated by the Drawings
or any mere imitation or modification thereof.
In witness whereof, we, the said George Frederick Graham and William
Payne have hereunto set our hands and seals this Twenty-fourth day
of January, in the year of our Lord One thousand eight hundred and
city five
GEO. FRED. GRAHAM. (L.8.)
WILLIAM PAYNE.
