PROVISIONAL SPECIFICATION left by the said George Ryder and John
Clay at the Office of the Commissioners of Patents, with their Petition,
on the 25th January 1860.
We, GEORGE RYDER, of Park Street, Lenton, in the County of Nottingham,
Engineer, and JOHN CLAY the younger, of Butcher Street, in the Town and
County of the Town of Nottingham, Engineer, do hereby declare the nature
of the said Invention for "A HIGH-PRESSURE STOP VALVE OR COCK," to be as
follows:-
Our Invention relates to the manufacturing of a high-pressure steam,
water, or fluid tap or valve for the regulation of steam, water, or other fluids,
and consists of a valve or plug worked by a crank or excentric which is
seated within, and can be used either with or without the operation of a

page_text: spring, and also without the use of packing; from the excellence of its
construction no leakage can arise, and liability to get out of repair is
prevented.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said George Ryder and John Clay in the Great Seal Patent
Office on the 24th July 1860.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, GEORGE
RYDER, of Park Street, Lenton, in the County of Nottingham, Engineer,
and JOHN CLAY the younger, of Butcher Street, in the Town and County of
the Town of Nottingham, Engineer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-fifth day of January, in the year of our Lord
One thousand eight hundred and sixty, in the twenty-third year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto us,
the said George Ryder and John Clay the younger, Her special licence that
we, the said George Ryder and John Clay the younger, our executors, adminis-
trators, and assigns, or such others as we, the said George Ryder and John
Clay the younger, 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
"A HIGH-PRESSURE STOP VALVE OR Cock," upon the condition (amongst others)
that we, the said George Ryder and John Clay the younger, 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 we, the said George Ryder and John Clay the
younger, do hereby declare the nature of the said Invention, and in what
manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement thereof, reference being had to the

page_text: accompanying Drawings, and to the letters and figures marked thereon,
that is to say:
Our Invention relates to the construction of a high-pressure steam, water,
or fluid tap or valve for the regulation of steam, water, or other fluids, and
consists of a valve or plug worked by a crank or excentric which is seated
within, and can be used either with or without the operation of a spring, and
also without the use of packing. From the excellence of construction of
this tap or valve no leakage can arise, and liability to get out of repair is
prevented.
We now proceed to explain our said Invention more particularly and
the mode of performing the same with reference to the accompanying
Drawings.
Figure 1 is a sectional view of our improved valve as cut through at right
angles to the crank pin or excentric; and Figure 2 is a view of the same
valve cut through at right angles with the last view, or in a line with the
axles of the crank; the valve is shewn as closed. A is the casing, the inside
of which is turned to form a seating for the valve or plug B, which has four
projections on one side, which serve as guides and ensure that the valve shall
move steadily while rising and falling. The valve is forced into its seat and
held closed by a crank pin C, bearing upon the upper side of a slot in the
lower side of the valve plug B, as shewn. D is a plug or ring screw-threaded
on its inner surface for a portion of its length, and also screw-threaded on its
outer surface for a portion of its length; this plug or ring is screwed into the
casing A after the valve plug B is inserted; the portion of the inner surface
of D, which is threaded, and the upper end of the casing A, which is also
threaded, are for screwing the valve to the ends of two pipes to be connected
or coupled. The crank pin C passes through a boss having a V-shaped
shoulder turned out on its inner side, as shewn at the right of Figure 2; the
boss is screwed into a projection on one side of the casing A; one end of the
crank pin projects beyond the boss, and has a key wrench E fitted upon it by
which the valve is opened or closed; the crank is kept close to the shoulder
of the boss by a spring lying between the other end of the pin and a plug F,
held in a smaller boss on the other side of the casing A.
And having now described the nature of our said Invention, and in
what manner the same may be performed, we declare that what we claim as
our Invention is, the arrangement and combination with the valve or plug
of a crank or excentric seated within the casing of the valve, to be used either

page_text: with or without a spring; and also without the use of. packing, ás herein-before
described and represented in the accompanying Drawings.
In witness whereof, we, the said George Ryder and John Clay the
younger; have hereunto set our hands and seals, this Twenty-third
day of July, in the year of our Lord One thousand eight hundred
and sixty.
GEORGE RYDER.
