Year: 1876

page_text: LETTERS PATENT to Thomas Goode Messenger, Mechanical Engineer, of Lough-
borough, in the County of Leicester, for the Invention of "IMPROVEMENTS
IN VALVES FOR THE CIRCULATION OF HOT WATER, WHICH IMPROVEMENTS ARE
ALSO APPLICABLE TO THE CIRCULATION OF COLD WATER, GAS, OR OTHER
FLUIDS"
Sealed the 5th January 1877, and dated the 25th July 1876.
PROVISIONAL SPECIFICATION left by the said Thomas Goode Messenger at
the Office of the Commissioners of Patents on the 25th July 1876.
THOMAS GOODE MESSENGER, Mechanical Engineer, of Loughborough, in the
County of Leicester. "IMPROVEMENTS IN VALVES FOR THE CIRCULATION OF HOT
WATER, WHICH IMPROVEMENTS ARE ALSO APPLICABLE TO THE CIRCULATION OF COLD
WATER, GAS, OR OTHER FLUIDS."
The improvements consist in forming a chamber with two or more valve seats
and valves constructed of brass, iron, india-rubber, or other suitable material,
opening and shutting upon the seatings as desired. Two or more valves are secured
to a spindle passing through a gland into the chamber containing the seatings,
which spindle forms the hinge of the valves, and it is actuated by a handle, toothed
quadrant, worin and wheel, or their equivalents.
By the foregoing means I am able to so arrange the valves that the operator can
open two valves in a direct line of pipes, and by the same operation can' close a
third valve on the seating of the partition across the chamber, which causes the
water to flow on over the top side of the chamber to the end of the system, and to
return back under the partition to the boiler; or by closing two valves in a direct
line of pipes, the one in the partition is opened when the water returns through this
part, so that the chamber forms what is commonly termed a syphon; or when
required without a partition, and it is desired to fix a valve or valves at each end
of the chamber, I connect one or more valves at one end of the chamber to the
corresponding valve or valves at the other end of the chamber, acted upon by worm
or otherwise, as before described, so that when one valve is opened the corresponding
one is closed; or both may be so adjusted that both valves may be partly open and
allow free circulation from both ends of the chamber through a pipe or pipes from

page_text: the boiler into the said chamber. The chamber or chambers is or are provided
with lids or covers to allow easy access to the valves for cleaning or repairs without
having to disturb the pipes.
If desired I cast with or secure to the said chamber a second chamber or water
space upon which four or more sockets are cast to receive as many pipes, so that
after the water has passed the valve or valves it circulates through as many pipes
as are provided for on the chamber or water space.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by the
said Thomas Goode Messenger in the Great Seal Patent Office on the 18th
January 1877.
THOMAS GOODE MESSENGER, Mechanical Engineer, of Loughborough, in the
County of Leicester. "IMPROVEMENTS IN VALVES FOR THE CIRCULATION OF HOT
WATER, WHICH IMPROVEMENTS ARE ALSO APPLICABLE TO THE CIRCULATION OF COLD
WATER, GAS, OR OTHER FLUIDS."
My improvements consist in the first place in forming a chamber with two or
more valve seats and valves constructed of brass, iron, india-rubber, or other suitable
material, to open and shut upon the seatings, as desired.
Secondly. In securing two or more valves to one or more spindles which pass
through a gland or glands into the chamber containing the seatings, the said spindle
or spindles form the hinge or hinges of the valves. This spindle or spindles is or
are acted upon by a handle, one or more toothed quadrants, worms and wheels
or their equivalents, the said quadrants may be fixed either inside or outside the
chamber, as desired.
Thirdly. By the foregoing means the valves can be arranged in such a manner
that the operator can open two valves in a direct line of pipes, and close a third
by the same operation on the seating of partition across the chamber, which causes
the water to flow on over the top side of the chamber to the end of the system and
return back under the partition to the boiler; or by closing two valves in direct
pipes the one in the partition is opened when the water returns through this port,
so that the chamber forms what is commonly called a syphon, as indicated by the
arrow; or when required without a partition, and to fix a valve or valves at
each end of the chamber, one or more valves are connected at one end of the
chamber to the corresponding valve or valves at the other end of the chamber,
acted upon by a worm and wheel as before described, so that when a valve or
valves is opened the corresponding valve or valves is closed, or both may be so
adjusted that the valve or valves at both ends may be partly open and allow free
circulation from both of the ends of the chamber through a pipe or pipes from the
boiler into the said chamber.
Fourthly. The said chamber or chambers is provided with a lid or lids, or
covers, to allow of access to the valves for cleaning or repairs without disturbing
the pipes.
Fifthly. If desired, I cast with or secure to the said chamber a second chamber
or water space, upon which four or more sockets or flanges are cast or secured to
receive as many pipes, so that after the water has passed the valve or valves
it circulates through as many pipes as are provided for on the chamber or water
space.
In the accompanying Drawings Figures 1, 2, and 3, are perspective views of the
various modifications of my Invention; and Figures 4, 5, and 6, are sections of the
same; the same letters of reference indicate like parts in all the Figures.
A are the valves in a direct line of pipes; B, valve in partition.; C, sockets to
receive the pipes; D, worm; E, wheel or handle; F, spindle; G, quadrant; H,
gland: I. lid.

page_text: Having thus described my Invention I claim,-
First. The employment of a chamber for one or more valves to work in simul-
taneously by one operation.
Secondly. In forming a partition in the said chamber, on which a valve works as
before described.
Thirdly. The employment of one or more spindles, arranged and actuated as
desired.
Fourthly. The employment of a second chamber to receive as many sockets or
flanges as may be desired, as described, to receive the water from the valve or
valves.
In witness whereof, I, the said Thomas Goode Messenger, have hereunto set
my hand and seal, this Fifteenth day of January, in the year of our Lord
One thousand eight hundred and seventy-seven.
