IMPROVEMENTS IN THE CONSTRUCTION OF VALVES
Year: 1861

page_text: LETTERS PATENT to Thomas Goode Messenger, of High Street, Lough-
borough, in the County of Leicester, Horticultural Builder and Plumber,
for the Invention of "IMPROVEMENTS IN THE CONSTRUCTION OF VALVES."
aled the 3rd January 1862, and dated the 11th July 1861.
PROVISIONAL SPECIFICATION left by the said Thomas Goode Messenger
at the Office of the Commissioners of Patents, with his Petition, on
the 11th July 1861.
I, THOMAS GOODE MESSENGER, of High Street, Loughborough, in the
County of Leicester, Horticultural Builder and Plumber, do hereby declare
the nature of the said Invention for "IMPROVEMENTS IN THE CONSTRUCTION OF
VALVES," to be as follows:-
My improvements consist in the first place in forming a chamber with a
valve seat and valve, constructed of brass or other suitable material, to open
quite back, so as to give the same capacity in the valve as that which is in
the pipe with which it is connected.
Secondly, in constructing a spindle working through a stuffing box; or inside
the chamber before mentioned, to which the above valve is attached, which
spindle forms the hinge of the valve; a toothed quadrant being fixed to the
said spindle is acted upon by a worm or screw and wheel, or by a handle or
other suitable contrivance, so that the operator may be enabled to open the
valve any required distance.
And, thirdly, in constructing a lid or door to be removed with ease and at
pleasure (should the valve require cleaning or repairing), without disturbing the
pipes or breaking a joint.

TO ALL TO WHOM THESE PRESENTS SHALL COME, I, THOMAS
GOODE MESSENGER, of High Street, Loughborough, in the County of Leicester,
Horticultural Builder and Plumber, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Eleventh day of July, in the year of our Lord
One thousand eight hundred and sixty-one, in the twenty-fifth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto
me, the said Thomas Goode Messenger, Her special licence that I, the said
Thomas Goode Messenger, my executors, administrators, and assigns, or
such others as I, the said Thomas Goode Messenger, 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 THE CONSTRUCTION OF
VALVES," upon the condition (amongst others) that I, the said Thomas
Goode Messenger, my executors or administrators, by an instrument in
writing under my, or their, or one of their hands and seals, should particu-
larly 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-
diately after the date of the said Letters Patent.
NOW KNOW YE, that I, the said Thomas Goode Messenger, 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 accompanying
Drawings, and to the letters and figures marked thereon, that is to say:-
My improvements consist in the first place in forming a chamber with a
valve seat and valve, constructed of brass or other suitable material, the valve
opening quite back, so as to give the same capacity in the valve as that which
is in the pipe with which it is connected.
Secondly, in constructing a spindle working through a stuffing box or inside
the chamber before mentioned, to which spindle the above valve is attached,
and which said spindle forms the hinge of the valve; a toothed quadrant is
fixed to the said spindle, and is acted upon by a worm or screw and wheel, or

page_text: by a handle or other suitable contrivance, so that the operator may be enabled
to open the valve any required distance.
And, thirdly, in constructing a lid or door which may be removed with ease
and at pleasure (should the valve require cleaning or repairing), without_dis-
turbing the pipes or breaking a joint.
I now proceed to explain my said Invention, more particularly with refer-
ence to the accompanying Drawings, which exemplify apparatus constructed
according to my Invention. .
Figure 1 is a perspective view, and Figure 2 a section. A is a socket which
receives the pipe to which the valve belongs; B is a chamber for the valve to
work in; C is a valve; D is the valve seat; E is the spindle or binge of the
valve; F is a stuffing box or gland through which the spindle works; G is a
toothed quadrant; H is the worm and I a wheel to work the worm; J is a lid
or door to the chamber b; and K a bolt by which the door is secured.
It may thus be seen that the valve C can be opened quite back in the
chamber B, so as not to obstruct the passage or fluid way; and that I can
regulate the extent to which the valve can be opened, that the spindle E is
worked by the quadrant G; when the valve is to be cleaned or repaired the
bolt K is unfastened and the door J opened, so that the valve can thus be
readily attained without disturbing the pipe or disconnecting the joints. The
door J may be secured by other ordinary attachments instead of the bolt K.
Having now described the nature of the said Invention and in what manner
the same may be performed, I declare that I claim,-
First, the employment of a chamber for a valve to work in, so that it may
open quite back therein, in the manner and for the purpose described.
Second, the employment of the valve spindle, arranged and actuated as
described.
Third, the arrangement and combination of parts herein-before described.
In witness whereof, I, the said Thomas Goode Messenger, have here-
unto set my hand and seal, this Ninth day of January, in the year
of our Lord One thousand eight hundred and sixty-two.
Witness,
GEO. JON. ROBINSON,
