IMPROVEMENTS IN COCKS, TAPS, AND VALVES
Year: 1866

page_text: LETTERS PATENT to William John Walsh, of Brentwood, in the County
of Essex, for the Invention of "IMPROVEMENTS IN COCKS, TAPS, AND
VALVES."
Sealed the 25th May 1866, and dated the 12th January 1866.
PROVISIONAL SPECIFICATION left by the said William John Walsh
at the Office of the Commissioners of Patents, with his Petition, on
the 12th January 1866.
I, WILLIAM JOHN WALSH, of Brentwood, in the County of Essex, do
5 hereby declare the nature of the said Invention for "IMPROVEMENTS IN COCKS,
TAPS, AND VALVES," to be as follows:-
These improvements have special reference to high-pressure cocks, taps,
and valves. I have a grooved or triangular spindle furnished with a knob or
top for the convenience of being pressed when it is desired to open the tap,
cock, or valve. On the said spindle is fitted a brass or other metal barrel
fitted with a valve at its upper and lower ends. Between these valves is the
aperture of the outflow pipe. To the bottom of the grooved or triangular
spindle above named is fitted a small valve, which is opened by pressing the
knob or top of the spindle. This small valve being opened, the water, steam,

page_text: or other fluid flows upwards along the grooves or sides of the spindle on to
the top of the upper valve situated at the top of the metal barrel, which
then becomes pressed down, opening the lower valve, when the water, steam,
or other fluid flows out. When the pressure on the spindle is withdrawn,
the force of the water, steam, or other fluid closes the small valve at the
bottom of the spindle, in consequence of which the pressure is removed from
the upper surface of the top valve, when the pressure in the other direction
forces the metal barrel back into its place, and so closes the cock, tap, or
valve. It can be effectually applied to throttle valves and stop, bib, and ball
cocks.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said William John Walsh in the Great Seal Patent Office on
the 6th June 1866.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
JOHN WALSH, of Brentwood, in the County of Essex, send greeting.
L
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters.
Patent, bearing date the Twelfth day of January, in the year of our Lord
One thousand eight hundred and sixty-five, in the twenty-ninth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said William John Walsh, Her special licence that I, the said William
John Walsh, my executors, administrators, and assigns, or such others
as I, the said William John Walsh, 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, TAPS, AND VALVES," upon the con-
dition (amongst others) that I, the said William John Walsh, 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 William John Walsh, do hereby
declare the nature of my said Invention, and in what manner the same

page_text: is to be performed, to be particularly described and ascertained in and by the
following statement:-
These improvements have special reference to high-pressure cocks, taps,
and valves. I have a grooved or triangular spindle furnished with knob or
top for the convenience of being pressed when it is desired to open the tap,
cock, or
valve. On the said spindle is fitted a brass or other metal barrel
fitted with a valve at its upper and lower ends. Between these valves is the
aperture of the outflow pipe. To the bottom of the grooved or triangular
spindle above named is fitted a small valve, which is opened by pressing the
knob or top of the spindle. The small valve being opened the water, steam,
or other fluid flows upwards along the grooves or sides of the spindle on to
the top of the upper valve situated at the top of the metal barrel which then
becomes pressed down, opening the lower valve, when the water, steam, or
other fluid flows out. When the pressure on the spindle is withdrawn the force
of the water, steam, or other fluid closes the small valve at the bottom of the
spindle, in consequence of which the pressure is removed from the upper
surface of the top valve, when the pressure in the other direction forces the
metal barrel back into its place and so closes the cock, tap, or valve. It can
be effectually applied to stop, bib, and ball cocks.
In order that my said Invention may be more clearly understood, I have
bereunto annexed a Drawing of a high-pressure tap constructed according to
my Invention. The Figure exhibits a vertical section of the tap or valve so
constructed. A is the spindle with the knob or handle B; this spindle as
already described is grooved at C, C, as shown; these grooves or channels
may be of any shape required. If the spindle be made triangular the grooves
will be formed by the space between the sides and the metal barrel D. To
the bottom of this spindle A is fixed the valve E. The spindle is made to
slide rather tightly through the cylinder D, so as to be impervious as far as
possible to the admission of water, steam, or other fluid for which the cock,
tap, or valve is used. The fluid thus rushes through the valve E and up the
grooves C, C, on to the upper surface of the valve F, which is attached to
the cylinder D, and the pressure of the fluid forces the cylinder down sufficiently
to open the valve H, when the fluid enters and flows off in any direction
required by the outlet G. I is an ordinary stuffing box for the spindle. A
and K is the inlet pipe.
I have thus completely described the nature and object of my said Invention
together with the best means I am acquainted with for carrying the same
into practical effect.
The Invention is capable of being successfully applied to stop, bib, and ball

page_text: cocks, and also to valves for regulating or limiting the supply or quantity of
water to closets or for the flushing or cleansing of the same. I would there.
fore have it distinctly understood that I do not confine myself to the precise
details or proportions of construction herein figured or described, but what I
claim as secured to me by Her Majesty's Letters Patent is, the special or
general mechanical arrangement or construction of the "Improvements in
Cocks, Taps, and Valves, herein-before described, illustrated, or referred to.
In witness whereof, I, the said William John Walsh, have hereunto set
my hand and seal, this Fifth day of June, in the year of our Lord One
thousand eight hundred and sixty-six.
WILLIAM JOHN WALSH. (L.S.)
