Year: 1871

page_text: LETTERS PATENT to Edward Thomas Hughes, of the Firm of Hughes
and Son, Patent Agents, 123, Chancery Lane, London, for the
Invention of "AN IMPROVED VALVE FOR STOPPING AND REGULATING THE
SUPPLY OF WATER, STEAM, GAS, AIR, AND OTHER SIMILAR PURPOSES.”÷A
communication from abroad by George Sigl, of Vienna, in the
Empire of Austria.
Scaled the 19th December 1871, and dated the 22nd June 1871.
PROVISIONAL SPECIFICATION left by the said Edward Thomas Hughes
at the Office of the Commissioners of Patents, with his Petition, on
the 22nd June 1871.
I, EDWARD THOMAS HUGHES, of the Firm of Hughes and Son, Patent
Agents, 123, Chancery. Lane, London, do hereby declare the nature of
the said Invention for "AN IMPROVED VALVE FOR STOPPING AND REGULATING
THE SUPPLY OF WATER, STEAM, GAS, AIE, AND OTHER SIMILAR PURPOSES,” (a
communication to me from abroad by George Sigl, of Vienna, in the
Empire of Austria,) to be as follows :—
The valve consists of two opposite cones with cylindrical ends which
can be moved nearer to or further from each other, and the seatings

page_text: of the cones are formed in a circular shell having at each side a
flange connected to the flanges of the conduit pipes. The shell is
strengthened by inner and outer ribs, the inner ribs being also used
to guide and steady the cylindrical ends of the cones, and at one
side of the shell there is an aperture or man-hole forming the entrance
into the interior of the shell. Between the cones, which are hollow
when they are of large dimensions, there is a hollow frame carrying the
mechanism for shifting the cones, and under this frame there are holes
for emptying the shell when the valve is shut. At the sides of the shell
there are tightening rings of gutta percha, lead, wood, or other material,
to suit the fluids or gases passing through the pipes, and the cones with
their cylindrical ends are only turned true at their tightening surfaces.
Inside the apex of each cone there is a pipe or socket, one having in it a
right-handed screwed thread and the other a left-handed end. Into
these threads are fitted corresponding screws at the ends of a rod or bar
to which is fixed a worm wheel, geared into a worm on a shaft extending
to the exterior of the shell and kept tight by a gland and packing, and
when the worm is turned in one direction the two cones are pressed to
the tightening rings and then the passages are stopped or shut, but
when the worm is turned in the reverse direction the passages are
opened. The working mechanism is enclosed between the cones, and
when the motions are required to be faster bevil wheels are used instead
of a worm and worm wheel, and also to ascertain the position of the
cones from their scatings I employ an indicator worked either from the
worm or bevil wheel shaft.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Edward Thomas Hughes in the Great Seal Patent
Office on the 22nd December 1871.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, EDWARD
THOMAS HUGHES, of the Firm of Hughes and Son, Patent Agents, 123,
Chancery Lane, London, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-second day of June, in the year
of our Lord One thousand eight hundred and seventy-one, in the thirty-
fifth year of Her reign, did, for Herself, Her heirs and successors,

page_text: give and grant unto me, the said Edward Thomas Hughes, Her special
licence that I, the said Edward Thomas Hughes, my executors, adminis-
trators, and assigns, or such others as I, the said Edward Thomas
Hughes, 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
“An Improved VALVE FOR STOPPING AND REGULATING the Supply of Water,
STEAM, GAS, AIR, AND OTHER SIMILAR PURPOSES," a communication to me
from abroad by George Sigl, of Vienna, in the Empire of Austria, upon
the condition (amongst others) that I, the said Edward Thomas Hughes,
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 imme-
dintoly after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Edward Thomas Hughes, do hereby
declare the nature of the said Invention, and in what manner the same
is to be performed, to be particularly described and ascertained in and
by the following statement, that is to say :-
The valve consists of two opposite cones with cylindrical ends which
can be moved nearer to or farther from each other, and the seatings of
the cones are formed in a circular shell, having at each side a flange
connected to the flanges of the conduit pipes. The shell is strengthened
by outer and inner ribs, the inner ribs being also used to guide and
steady the cylindrical ends of the cones, and at one side of the shell
there is an aperture or man-hole forming the entrance into the interior
of the shell. Between the cones, which are hollow when they are of
large dimensions, there is a hollow frame carrying the mechanism for
shifting the cones, and under this frame there are holes for emptying
the shell when the valve is shut. At the sides of the shell there are
tightened rings of gutta percha, lead, wood, or other material to suit the
fluids or gases passing through the pipes, and the cones with their
cylindrical ends are only turned true at their tightening surfaces. Inside
the apex of each cone there is a pipe or socket, one having in it a right-
handed screwed thread, and the other a left handed, and into these

page_text: threads are fitted corresponding screws at the ends of a rod or bar, to
which is fixed a worm wheel geared into a worm on a shaft extending to
the exterior of the shell, and kept tight by a gland and packing; and
when the worm is turned in one direction the two cones are pressed
to the tightening rings, and then the passages are stopped or shut, but
when the worm is turned in the reverse direction the passages are
opened. The working mechanism is enclosed between the cones, and
when the motions are required to be faster bevil wheels are used - instead
of a worm and worm wheel, and also to ascertain the position of the
cones from their seatings I employ an indicator worked either from the
worm or bevil wheel shaft.
In the accompanying Drawings Figure 1 is a longitudinal section of
the valve with the valve cones open. In the interior of the latter the
mechanism with its conical wheels is drawn in dotted lines. In Figure 2
the same arrangement is shewn with the valves shut. Figure 3. repre- 1
sents shows a cross cut of the shell, the movement of the cones being
effected by a screw wheel; and Figures 4 and 5 show a cross cut and
longitudinal section of the shell, the movement of the cones being
effected by spur wheels.
In all the Figures a represents the shell consisting of two parts, and :
strengthened by the outer ribs 6 and inner ribs c, which latter support
and guide the valve cones; d is the manhole or aperture in the shell,
and e the opening or openings for discharging the water; f.f, are the
rings of gutta percha, lead, wood, or other material; 9, a support for
the bearings of the spindle h, having on one side a left thread, on the
other a right one. Between the two bearings, the support leaves room
for the pinion wheel which is either conical (as in Figures 1 and 2), or a
worm wheel (Figure 3), or a spur wheel (Figures 4 and 5). The two
valve cones i, i, are cast hollow and strengthened by ribs, and are turned
upon the cylindrical ring which supports the guides . In the socket is
contained the nut for the spindle. As the cones at the opening of
the valve (Figure 1) must meet the edges of the parts enclosing the
mechanism the cylindrical parts must be cut out where the beam g
and shaft 2 would come in contact; m is the indicator which indicates
the position of the valve.
Having now described the nature and particulars of the said Inven-
tion, I desire it to be understood that I claim the improved valve for
stopping and regulating the supply of water, steam, gas, air, and other

page_text: similar purposes, as herein particularly described and illustrated in the
accompanying Drawings.
In witness whereof, I, the said Edward Thomas Hughes, have here-
unto set my hand and seal, this Twenty-second day of December,
in the year of our Lord One thousand eight hundred and seventy-
one.
