Year: 1867

page_text: LETTERS PATENT to Joseph Whitley, of the Railway Brass Works, Leeds,
in the County of York, for the Invention of "IMPROVEMENTS IN STOP
VALVES OR TAPS FOR STEAM AND WATER."
Sealed the 17th September 1867, and dated the 22nd March 1867.
PROVISIONAL SPECIFICATION leit by the said Joseph Whitley at the
Oflice of the Commissioners of Patents, with his Petition, on the 22nd
March 1867.
1, JOSEPH WHITLEY. of the Railway Brass Works, Leeds, in the County of
York, do hereby declare the nature of the said Invention for "IMPROVEMENTS
IN STOP VALVES OR TAPS FOR STEAM AND WATER." to be as follows:-
This Invention has for its object improvements in stop valves or taps for
steam and water.
A valve or tap in which the inlet and outlet pipes are at right angles to
each other is according to this Invention constructed in the following
manner-The body or shell of the valve or tap has a socket on one side,
which is tapped with a screw thread to receive one of the pipes. At one end
of the body there is another socket of larger size also tapped with a screw
thread, and it receives a screw plug through which a passage is formed and
tapped to receive the other of the two pipes, it may be the inlet or the
outlet. A valve seat is formed on the plug at its inner end. and the valve to
close the passage through the plug is formed at the end of a stem which
passes out at the other end of the body or shell through a stuffing box. At
[Price Bd.]

page_text: this end the exterior of the shell or body has a screw thread cut upon it to
receive the cap of the stuffing box. The stem of the valve passes out through
the cap, and has a screw thread upon it, and a corresponding thread is cut
in the passage through the cap: thus by turning the valve stem by means of
a key or handle applied at its outer end it can be screwed in or out through
the cap, and in this way the valve is removed from its seat, or forced firmly
against it. Where the inlet and outlet pipes are in one straight line the
arrangement is similar, except that the sockets on the side of the body and in
the screw plug at the end thereof are set at a suitable inclination to the
passage through the body or shell.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Joseph Whitley in the Great Seal Patent Office on the
21st September 1867.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOSEPH
WHITLEY, of the Railway Brass Works, Leeds, in the County of York, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-second day of March, in the year of our Lord
One thousand eight hundred and sixty-seven, in the thirtieth year of Her reign.
did, for Ierself. Her heirs and successors, give and grant unto me. the said
Joseph Whitley. Her special licence that I, the said Joseph Whitley, my
executors, administrators, and assigns, or such others as I, the said Joseph
Whitley, 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 STOP VALVES OB
TAPS FOR STEAM AND WATER," upon the condition (amongst others) that I,
the said Joseph Whitley, my executors or administrators, by an instrument
in writing under my, or their, or one of their hands and seals. should par-
ticularly 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 1. the said Joseph Whitley. do hereby declare the
nature of the said Invention, and in what manner the same is to be per-

page_text: formed, to be particularly described and ascertained in and by the following
statement thereof, that is to say:-
This Invention has for its object improvements in stop valves or taps for
steam and water.
A valve or tap in which the inlet and outlet pipes are at right angles
to each other is according to this Invention constructed in the following
manner: The body or shell for the valve or tap has a socket on one side,
which is tapped with a screw thread to receive one of the pipes. At one end
of the body there is another socket of larger size also tapped with a screw
thread, and it receives a screw plug through which a passage is formed and
tapped to receive the other of the two pipes. A valve seat is formed or
mounted on the plug at its inner end, and the valve to close the passage
through the plug is formed to work in or carried at the end of a spindle which
passes out at the other end of the body or shell through a stulling box. At
this end the exterior of the shell or body has a screw thread cut upon it to
receive the cap of the stuffing box. The spindle which carries or holds the
valve in position passes out through the cap, and has a screw thread upon it,
and a corresponding thread is cut in the passage through the cap; thus by
turning the valve spindle by means of a wheel or handle applied at its outer
end it can be screwed in or out through the cap, and in this way the valve
is removed from its seat, or forced firmly against it. Where the inlet and
outlet pipes are in one straight line the arrangement is similar. except that
the sockets on the side of the body and in the screw plug at the end thereof
are set at a suitable inclination to the passage through the body or shell.
And in order that my said Invention may be most fully understood and
readily carried into effect, I will proceed to describe the Drawings hereunto
annexed.
DESCRIPTION OF THE DRAWINGS.
Figure is a longitudinal section of a stop valve or tap constructed
according to my Invention; Figure 2 is an outside view; Figures 3 and 4 are
opposite end views of the same; Figure 5 is a section taken at the line A. B.
Figures and 2: in this arrangement the inlet and outlet pipes are at right
angles to each other.
a, a, is the body or shell of the valve or tap, and a¹ is a socket at the side
of it to receive the delivery or outlet pipe b which is screwed into it: " is a
larger socket at one end of the body or shell with a screw thread cut within it
to receive the screw plug c. into which the supply or inlet pipe d is screwed;
el is a valve seat at the end of the plug : it may be formed in one piece with

page_text: it. but it is preferred that it should be separate, and held in its place by the
plug c, a lead or other washer being introduced between the two to ensure a
light joint. This arrangement admits of the valve seat being renewed when it
is worn out at very slight expense. e is the valve, and e' a spindle, which can
be in one piece with the valve; it is, however, much better and more con-
venient to make them separate, as the Drawing shows, the valve having a
shank or pin fitting loosely into the hollow end of the spindle e¹. The
spindle e passes out of the body or shell by a stuffing box, and has a screw thread
cut upon it, which works with a similar thread cut in the cap or cover f of
the stuffing box. The cap or cover f screws on to the end of the body or shell,
which has a thread to receive it, as is shown. The stuffing box is packed
with hemp or other suitable material around the spindle, over which a
ferrule is placed, which is pressed down by screwing on the cap or cover f.
The outer end of the spindle e¹ receives a hand wheel by which it is turned
similar to those used for cast-iron and other valve taps.
Figure 6 is a longitudinal section, and Figure 7 an outside view of a stop
valve or tap arranged according to my Invention, but in which the inlet and
outlet pipes are in one straight line; Figure 8 is a portion of an end view of
the same; and Figure 9 is a section taken at the line C, D, E, Figure 6. It
will be seen that the arrangement remains in substance the same, but that the
supply or inlet pipe is adapted to a curved passage in the plug c, and the
delivery or outlet pipe to a curved socket d' at the side of the body or shell.
Having thus described the nature of my Invention, and the manner of per-
forming the same, I would have it understood that what 1 claim is, the
constructing stop valves or taps substantially in the manner herein-before
described. and particularly the forming the same with portable seats as
described.
In witness whereof. I. the said Joseph Whitley, have hereunto set my
hand and seal, this Nineteenth day of September, in the year of our
Lord One thousand eight hundred and sixty-seven.
