IMPROVEMENTS IN STEAM AND WATER VALVES, COCKS, AND FAUCETS
Year: 1868

page_text: LETTERS PATENT to Clinton Edgcumbe Brooman, of the Firm of
Robertson, Brooman, and Company, of 166, Fleet Street, in the
City of London, Patent Agents, for the Invention of "IMPROVEMENTS
IN STEAM AND WATER VALVES, COCKS, AND FAUCETS."-A communication
from abroad by Henry Gurney Morris, of Philadelphia, United
States of America.
Sealed the 19th June 1868, and dated the 3rd February 1868.
PROVISIONAL SPECIFICATION left by the said Clinton Edgcumbe
Brooman at the Office of the Commissioners of Patents, with his
Petition, on the 3rd February 1868.
I, CLINTON EDGCUMBE BROOMAN, of the Firm of Robertson, Brooman,
and Company, of 166, Fleet Street, in the City of London, Patent
Agents, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN STEAM AND WATER VALVES, COCKS, AND FAUCETS," to be as
follows:-
It has been found very difficult to prevent the leakage of steam or
water round the stems of steam or water valves or faucets, and many
plans besides the ordinary gland or stuffing have been devised and

page_text: used; the novel method whereby I propose to obviate this difficulty will
be understood by referring to the accompanying Drawings, which I now
proceed to describe.
Figure 1 is a sectional elevation, and Figure 2 a horizontal section on
the line x, y, of a globe valve constructed according to this Invention.
I employ to operate the valve a stem A which can be turned or
rotated by the wheel B, by means of the spline or feather C; this stem
has a collar D which is scaled at d, d, upon the centre picco E and made
to form with it a steam or water tight joint, the pressure of the steam
or water and the nut F upon the stem above the turning wheel or
handle holding the collar up to its seat. The collar may be held to its
seat by a spring or rivet in place of the nut F if more convenient.
Below this collar I give to the stem A of the valve the form in section
of a square polygon or key (as shown), or place a spline or feather in
the same in order that it can be entered into a sleeve within the valve
spindle or screw G fitting loosely in the same, so that when the stem is
turned the spindle sliding freely upon it will be raised or depressed by
means of the thread upon the outside of the spindle which runs in the
nut formed at g, g, in the centro piece E. By this construction the
strain of seating the valve disc J is expanded between the seat of
the disc and the fixed centre piece, and the collar D is exposed to
comparatively little strain or wear in service.
I have also shewn in the Drawing the mode whereby I construct
a globe valve with a loose disc so as to reduce the parts to practical
dimensions in combination with the enlarged valve spindle. I form the
bottom of the valve spindle with an intersect thread, into which I screw
the collared nut H, having previously slipped upon the spindle the
loose fitting ring I, which ring I screw tightly into the disc J, letting it
make up on the shoulder at k, so that the disc will be free to rotate on
the end of the spindle (the nut H) and thus avoid any grinding action
on the seat when the valve is opened or shut.
This Invention is also applicable to faucets with leather or rubber or
metal seats, to guage cocks, and to other cocks, valves, and faucets having
different form from the globe valve shewn in the Drawing.
I am aware that it is not new to make valves and faucets with collars
on the stems, which collars have been held to a seat upon the centre
piece, and with the screw thread for operating the valve upon the stem
below the collar, which thread runs within a nut formed within a valve

page_text: spindle of square, polygonal, key-formed, or splined, external shape
to prevent the spindle from turning when the valve is raised or
depressed; but what is new in this Invention is, the construction of
valves, cocks, and faucets in which the stem has a key or other suitable
section for turning the screw or spindle, which raises or depresses the
disc as herein-before described. And the attachment of the loose disc
to the spindle by the collared nut H, and the following nut I, as
herein-before described.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said Clinton Edgcumbe Brooman in the Great Scal
Patent Ofice on the 14th July 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, CLINTON
EDGCUMBE BROOMAN, of the Firm of Robertson, Brooman, and
Company, of 166, Fleet Street, in the City of London, Patent Agents,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Third day of February, in the year
of our Lord One thousand eight hundred and sixty-eight, in the thirty-
first year of Her reign, did for Herself, Her heirs and successors,
give and grant unto me, the said Clinton Edgcumbe Brooman, Her
special licence, that I, the said Clinton Edgcumbe Brooman, my
executors, administrators, and assigns, or such others, as I, the said
Clinton Edgcumbe Brooman, 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 STEAM AND WATER VALVES,
COCKS, AND FAUCETS," (communicated to me from abroad by Henry Gurney
Morris, of Philadelphia, in the United States of America,) upon the
condition (amongst others) that I, the said Clinton Edgcumbe Brooman,
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

page_text: 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 Clinton Edgcumbe Brooman, 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 thereof, reference being had to the
Drawings hereunto annexed, that is to say :-
It has been found very difficult to prevent the leakage of steam or
water round the stems of steam or water valves or faucets, and many
plans besides the ordinary gland or stuffing box have been devised and
used; the novel method whereby I obviate this difficulty will be
understood by referring to the accompanying Drawings, which I now
proceed to describe.
Figure 1 is a sectional elevation, and Figure 2 a horizontal section on
the line x, y, of a globe valve constructed according to this Invention.
I employ to operate the valve a stem A which can be turned or
rotated by the wheel B by means of the spline or feather C; this stem
has a collar D which is seated at d, d, upon the centre picce E, and
made to form with it a steam or water tight joint, the pressure of the
steam or water and the nut F upon the stem above the turning wheel or
handle holding the collar up to its seat. The collar may be held to its
seat by a spring or rivet in place of the nut F if more convenient.
Below this collar I give to the stem A of the valve the form in section
of a square, polygon, or key (as shown), or place a spline or feather in
the same in order that it can be entered into a sleeve within the valve
spindle or screw G fitting loosely in the same, so that when the stem is
turned the spindle sliding freely upon it will be raised or depressed
by means of the thread upon the outside of the spindle which runs in
the nut formed at g, g, in the centre piece E. By this construction the
strain of seating the valve disc J is expanded between the seat of the
disc and the fixed centre piece, and the collar D is exposed to com-
paratively little strain or wear in service.
I also shew in the Drawing the mode whereby I construct a globe
valve with a loose disc, so as to reduce the parts to practical dimensions
in combination with the enlarged valve spindle. I form the bottom of
the valve spindle with an intersect thread, into which I scrow the
collared nut H, having previously slipped upon the spindle the loose
fitting ring I, which ring I screw tightly into the disc J, letting it make

page_text: up on the shoulder at k, so that the disc will be free to rotate on the
end of the spindle (the nut H) and thus avoid any grinding action on
the scat when the valve is opened or shut.
This Invention is also applicable to faucets with leather or rubber
or metal seats, to gauge cocks, and to other cocks, valves, and faucets,
having different form from the globe valve shewn in the Drawing.
I am aware that it is not new to make valves and faucets with collars
on the stems, which collars have been held to a seat upon the centre
piece, and with the screw thread for operating the valve upon the stem
below the collar, which thread runs within a nut formed within a valve
spindle of square, polygonal, key-formed, or splined external shape, to
prevent the spindle from turning when the valve is raised or depressed;
but what I claim as new is,-
The construction of valves, cocks, and faucets in which the stem
has a key or other suitable section for turning the screw or spindle
which raises or depresses the disc, as herein-before described.
And, secondly, the attachment of the loose disc to the spindle by the
collared nut H and the following nut I, as hercin-before described.
In witness whereof, I, the said Clinton Edgcumbe Brooman, have
hercunto set my hand and seal, this Fourteenth day of July,
One thousand eight hundred and sixty-eight.
