IMPROVEMENTS IN VALVES, AND IN MEANS FOR REGULATING AND INDICATING THE FLOW AND PRESSURE OF FLUIDS
Year: 1862

page_text: LETTERS PATENT to Joseph Walter Taylor, of Newsome, near Hudders-
field, in the County of York, Manufacturer, for the Invention of
"IMPROVEMENTS IN VALVES, AND IN MEANS FOR REGULATING AND INDICATING
THE FLOW AND PRESSURE OF FLUIDS."
PROVISIONAL SPECIFICATION left by the said Joseph Walter Taylor at
the Office of the Commissioners of Patents, with his Petition, on the
20th June 1862.
I, JOSEPH WALTER TAYLOR, of Newsome, near Huddersfield, in the County
of York, Manufacturer, do hereby declare the nature of the, said Invention
for "IMPROVEMENTS IN VALVES, AND IN MEANS FOR REGULATING AND INDICATING
THE FLOW AND PRESSURE OF FLUIDS," to be as follows:-
The improvements in valves consist in forming the plugs thereof of india-
rubber, such plugs being, secured by screw nuts or other, suitable means
between flanges or washers to the spindle. For indicating the pressure of
liquids I apply a small ram or piston in a cylinder, the lower end of which
ram is pressed on by the fluid whilst the upper end acts by links or connecting
rods upon weighted levers to raise the weights thereof as the pressure increases,
and at the same time an axis with pointer is set in motion to indicate the

page_text: pressure exerted. Also to means of regulating the flow of water obtained by
condensation. For this purpose I apply to a chamber used as a receiver of
such water an outlet passage with a valve (capable of closing the same) to
which is applied a float adapted to open such valve with the rise of the water
in such chamber, and admit of the escape of such water whilst at other times
the tendency is for the valve to be closed.
By another arrangement the steam and the water of condensation pass
into a chamber of some considerable length to admit of perceptible expansion
and contraction in the length of a pipe placed within this chamber; this pipe
is formed of copper or other metal of more expanding property than the
chamber in which it is contained, and one end of it is fixed and communicates
with a waste pipe or passage open to the atmosphere, whilst to the other end
of it is applied a valve capable of being set by a screw and compensating
spring as required.
Another part of the improvements relates to apparatus for regulating
the pressure and flow of gaseous fluids. The gaseous fluids pass through a
chamber having a cover which is capable of being. weighted to the desired
pressure, and has a rim projecting downwards into a trough of mercury by
which such cover is capable of being lifted without permitting the escape of
the gas. The gas passes into this chamber by a passage regulated by a valve
suspended from the cover referred to, and this passage is formed in a block
with a surrounding edge also dipping into a channel of mercury. By this
arrangement of the parts in the event of any derangement they are readily
repaired and replaced.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Joseph Walter Taylor in the Great Seal Patent Office on
the 20th December 1862.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOSEPH
WALTER TAYLOR, of Newsome, near Huddersfield, in the County of York,
Manufacturer, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her. Letters
Patent, bearing date the Twentieth day of June, in the year of our Lord 'One.
thousand eight hundred and sixty-two, in the twenty-sixth year of Her reign,
did, for Herself, Her heirs and successors, give and grant unto me, the said.

page_text: Joseph Walter Taylor, Her special licence, that I, the said Joseph Walter Taylor,
my executors, administrators, and assigns, or such others as I, the said Joseph
Walter Taylor, 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 VALVES, AND
IN MEANS FOR REGULATING AND INDICATING THE FLOW AND PRESSURE OF FLUIDS,"
upon the condition (amongst others) that I, the said Joseph Walter Taylor,
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 per-
formed, 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 I, the said Joseph Walter Taylor, do hereby declare
the nature of the said Invention, and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement thereof, that is to say:-
..
The improvements in valves consist in forming the plugs thereof of india-
rubber, such plugs being secured by screw nuts or other suitable means
between flanges or washers; to the spindle. For indicating the pressure of
liquids I apply a small ram or piston in a cylinder the lower end of which
ram is pressed on by the fluid whilst the upper end acts by links or connect-
ing rods upon weighted levers to raise the weights thereof as the pressure
increases, and at the same time an axis with pointer is set in motion to
indicate the pressure exerted.
The improvements relate also to means of regulating the flow of water
obtained by condensation. For this purpose I apply to a chamber used as a
receiver of such water an outlet passage with a valve (capable of closing the
same) to which is applied a float adapted to open such valve with the rise of
the water in such chamber and admit of the escape of such water, whilst at
other times the tendency is for the valve to be closed.
By another arrangement the steam and the water of condensation pass
into a chamber of some considerable length to admit of perceptible expansion
and contraction in the length of a pipe placed within this chamber; this pipe
is formed of copper or other metal of more expanding property than the
chamber in which it is contained, and one end of it is fixed and communicates

page_text: ascertained, is caused to, flow into the chamber f so as to act upon the under
side of the piston g with a tendency to force that piston upwards through the
stuffing box g', and in so doing to raise the segment h with the two bands i, i,
attached thereto., The lower ends of these bands are by pin joints i connected
to levers j, j, which turn, on axes j, j, and at their outer ends carry
weights adapted when raised by the rising of the piston g, drawing the
bands upwards, to expand at their outer weighted ends, and thereby exert
greater force on the piston; on one of the axes 7, affixed to that lever j is
affixed the pinion 33, indicated by red lines; the teeth of this pinion take into
the teeth of a pinion k upon the axis of a pointer k', the position of which
indicates the pressure exerted.
Figure 10 shews a section of apparatus arranged according to my improve-
ments for regulating the flow of water obtained by condensation. I is a
chamber acting as a receiver for water of condensation flowing therein by. the
passage; is the outlet passage which is capable of being closed by a
valve m, which I prefer to be constructed according to the first part of these
improvements, but it may be otherwise constructed. This valve m will remain
closed until the quantity of water collected in the vessel l.rises sufficiently high
to raise the float ml, attached to one end of the rod m³, the other end of which
turns upon a fixed axis m³, whilst at n it is connected. to the valve m, and
then, so long the float m¹ is kept raised to raise the valve m, the water
obtained by condensation will flow away. When there is not sufficient water
in the chamber 1-to open the valve m by raising the float m', that valve will
remain closed. n is a valve with parts adapted to admit of the escape of the
air or steam flowing over into the chamber with the water of condensation.
The valve n is capable of fitting into so as to close the seat o, and it is con-
nected by a spindle n' passing through the guide o¹ to the cap 7, which is
formed with a turned over upper.edge n³ adapted when down to rest on the
seat o, whilst the lower part of this cap n² is conical so that as it rises in the
seat the annular space formed becomes considerably increased. And the
distance between the parts n and n³ on the spindle n³ may be varied and then
set by the set screw n', in order that when the valve n. is fully.open the
cap n may, at its upper edge n³, be closed upon its seat o³, or be more or less
open according to the pressure exerted.
.
Figure 11 shews a slight modification of Figure 10, but the same letters
indicate corresponding parts, and the same description applies.
Figure 12 shews a longitudinal section of
for regulating the flow of condensed water.
another modification of apparatus
In this case the steam and water

page_text: of condensation pass into a chamber p of considerable length, say, 10 or 12 feet
in length from one end to the other, sufficient to admit of perceptible difference
in length by expansion and contraction of a pipe q placed in the chamber p, the
chamber p being formed of iron or other metal or material of low expanding
power, and the pipe 9 being formed of copper or other metal of comparatively
high expanding power than that of which the chamber p is formed; one end
q of this pipe q is fixed to the chamber p, and at that end it communicates
with a waste pipe or passager open to the atmosphere or to a suitable conduit,
whilst at the opposite end q is applied a valve s capable of being adjusted in
its distance from the end of the pipe q by turning the handle s¹, the spindle of
which is formed with a screw thread s². The end of the pipe.q is formed
with an enlargement bell-mouthed to slide in the bearing p¹ of the chamber
pp is an inlet to the chamber p. The water passing thence into the pipe q
between the end q² thereof and the valve s will, according to the amount of
heat contained therein, cause the pipe 9 to expand and vary the amount of
opening between that end of the pipe 9 and the valve s, such variation being
apart from that obtained by the spindle s².
Figure 13 shews a section of apparatus arranged for regulating the pressure
and flow of gaseous fluids. The gaseous fluid, the pressure of which is to be
regulated, passes into the chamber t by the passage t', and thence between the
valve u and the seat of the valve v. The valve u is supported by the spindle
u which is affixed to the cover u², whilst it slides in the upper portion t2 of the
case t, so as to be guided thereby, whilst by the pressure of the gaseous fluid.
the cover u² is capable of being raised. This cover is formed with a turned
down edge to pass into the channel or reservoir 3 supplied with mercury, and
it is weighted to the extent desired by a weight u³, the lower edge u' of which
rests in the trough of mercury t, the gas escapes by the passage t*.
Having thus described the nature of my said Invention, and means which I
have found to answer in carrying the same into effect, I would have it under-
stood that I do not confine myself to the precise details shown and described,
as these may be varied, but what I do claim is,―
First, the improvements in valves, substantially as explained in respect of
Figures 1, 2, 3, 4, 5, 6, 7 and 8.
Secondly, I claim the adaptation or combination of means for indicating the
pressure of fluids, substantially as explained in respect of Figure 9.
Thirdly, I claim the combination of means for regulating the flow of water
obtained by condensation, substantially as explained in respect of Figures 10
and 11.

page_text: Fourthly, I claim the adaptation or combination of means for regulating
the flow of water obtained by condensation, substantially as explained in respect
of Figure 12.
Fifthly, I claim the adaptation or combination of means for regulating the
flow of gaseous fluids, substantially as explained in respect of Figure 13..
In witness whereof, I, the said Joseph Walter Taylor, have hereunto
set my hand and seal, this Fifteenth day of December, in the year
of our Lord One thousand eight hundred and sixty-two.
