IMPROVEMENTS APPLI- CABLE TO STEAM PIPES USED FOR WARMING, DRYING, OR VENTEATING
Year: 1853

page_text: LETTERS PATENT to Wright Jones, of Pendleton, in the County of
Lancaster, Engineer, for the Invention of "IMPROVEMENTS APPLI-
CABLE TO STEAM PIPES USED FOR WARMING, DRYING, OR VENTEATING."
PROVISIONAL SPECIFICATION left by the said Wright Jones at
་་ the Office of the Commissioners of Patents, with his Petition, on
+
the 21st February 1853.
I, WRIGHT JONES, of Pendleton, in the County of Lancaster,
Engineer, do hereby declare the nature of the said Invention for "IM-
PROVEMENTS APPLICABLE TO STEAM PIPES USED FOR WARMING, DRYING, OR
VENTILATING," to be as follows:-
My Invention relates to an apparatus to be connected to steam-pipes
for the purpose of carrying off the air and water contained in such
pipes when the steam is admitted thereto, the chief object being to
effect such operation without that loss of steam which usually takes
place, and the escape of which is also productive of much incon-
venience. The improved apparatus consists of a chamber connected to.
the steam-piping by a suitable communication. In this chamber are
two valves; the one at the lower part designed for the passage of water,
and the other at a greater elevation for the passage of air. When

page_text: steam is admitted to the piping, the first action will be to drive the
contained air before it into the chamber, from which it will pass
through the valve
apted for that purpose; after this the water con-
tained in the pipes and produced by condensation of steam will
be driven into the chamber, and by accumulating there will close the
air-valve by means of an ordinary float; at the same time, a float con-
nected with the other valve will rise so as to lift it from its seat, and
thereby open a passage for the exit of the water; after this the com-
munication between the chamber and the steam-piping will be closed
until required again for the same purpose. The water left in the
chamber by the operations above described will slowly pass through
a small hole formed in the valve or elsewhere.
SPECIFICATION in pursuance of the conditions of the Letters Patent
filed by the said Wright Jones, in the Great Seal Patent Office,
on the 19th August 1853.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
WRIGHT JONES, of Pendleton, in the County of Lancaster, Engineer,
send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her
Letters Patent, bearing date the Twenty-first of February One
thousand eight hundred and fifty-three, in the sixteenth year of
Her reign, did for Herself, Her heirs and successors, give an
grant unto me, the said Wright Jones, Her especial licence that
I, the said Wright Jones, 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 APPLICABLE TO STEAM
PIPES USED FOR WARMING, DRYING, OR VENTILATING," upon the condition
(amongst others) that I, the said Wright Jones, by an instrument in
writing under my hand and seal, should particularly describe and
ascertain the nature of the said Invention, and in what manner the

page_text: 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 I, the said Wright Jones, do hereby declare
the nature of my said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the
following statement, and accompanying drawings (that is to say):
is
My Invention relates to an apparatus to be connected to steam-pipes
for the purpose of carrying off the air and water contained in such
pipes when steam is admitted thereto, the chief object being to effect
such operation without that loss of steam which usually takes place,
and the escape of which is also productive of much inconvenience.
The apparatus I employ admits of much modification, and I have in
the accompanying drawings shown two arrangements by which the
main features of my Invention will be fully illustrated. Figs. 1, 2,
and 3, represent the first form of apparatus which I shall describe.
Fig. 1, is a vertical section thereof; Fig. 2, a top view with the
cover removed; and Fig. 3, a cross section. The exterior casing
of the apparatus is shown at a, to which a steam-tight cover b, is
adapted and secured by bolts; beneath the casing is a channel c, open
to the atmosphere by a pipe d; communicating with the channel c,
a barrel e, the upper end of which is provided with a valve f, connected
by means of links to a lever g, which lever is capable of turning upon
a centre at h, and carries at its other extremity a float i, situate within
a chamber j, between which and the outward chamber a, a communica-
tion is established by means of an aperture at k. At the lower part of
the casing a, there is a seat provided with a valve l, connected by
means of links to the lever m, of a float n. The apparatus thus con-
structed is to be placed in any convenient situation, and a commu-
nication effected with the steam-pipe used for warming, drying, or
ventilating, by means of the pipe o. The operation will then be as
follows. Upon steam being admitted, the air contained in the pipes
will be driven forward through the pipe o, into the chamber a, from
whence it will escape through the valve f, (at this time open) and

page_text: passage c. Whenever this shall have taken place the water arising
from the condensed steam will be driven forward, and by passing in its
turn through the pipe o, will flow through the aperture k, into the
chamber, j, lifting the ball i, by its accumulation. The effect of this will be,
that the lever g, will be turned upon its centre so as to allow the valve f,

to fall upon its seat, thereby closing up the communication between
the chamber a, and passage c: this will have taken place by the time
that the warming, drying, or ventilating pipes supply steam through
the pipe o, which will therefore fill the chamber a, but cannot escape
therefrom. An accumulation of water above a certain point will float
the ball n, so as to raise the valve l, and allow it to escape through
the passage c, to any convenient situation. In order that the air-
passage may be open when the apparatus is cold, I cut a small notch
in the seat of the valve 1, through which the water not capable of
being removed by the action of the float n, will pass, and thereby
allow the float i, to fall, so as to effect an opening of the valve f. It will
be observed by the foregoing description, that according to my improved
apparatus there are not any valves or taps necessary to be regulated
by hand, the passage for the discharge of air being self-acting, closing,
when its office has been accomplished, so as to prevent an escape of
steam. Fig. 4, represents in longitudinal section, and Fig. 5, in
plan view, a modification of my invention, the variations being that
in this case the self-acting air-valve is also used for the discharge of
water; and instead of the float i, before mentioned, an apparatus acting
by expansion is employed for closing the air-passage. At the bottom.
of the chamber a, 'there is, as before, a passage c, and pipe d, the
said passage being in communication with a valve f. This valve is
suspended by links p, p, to one end of a lever q, the other extremity.
thereof being capable of turning upon a centre at r, and provided with
a tail-piece s, so as to form a bell-crank lever. The parts, passes
through the slot of a bar t, one end of which it supports by means of
a projection; the other end of the bar t, is bolted firmly to the casing
a, (see the enlarged detached view, Fig. 6). Through the link p*,
of the valve f, a lever m, passes, turning upon a centre, and provided
with a float n, at its other extremity. The action of this modification

page_text: :
of my Invention is as follows:-Upon steam being admitted to the
warming, drying, or ventilating pipes, the air will, as before, be driven
through the pipe o, into the chamber a, and will escape through the
valve f, passage c, and pipe d. This aperture will remain open until
steam shall have supplied the place of air, and the chamber a, become
filled therewith, at which time the bar t, being heated, will expand
in length so as to carry the end t*, of its slot (Fig. 6) forward,
which, being now therefore situate above a lower portion of the inclined
nib of the parts, the lever q, will be free to turn upon its centre, so
as to allow the valve f, to fall; and the passage c, will be.closed; thus,
by a self-acting operation, preventing, as before, an escape of steam.
Whenever the water arising from condensation shall have attained
a certain level, the float n, will have been raised, so as to cause its
lever m, to bear against the upper part of the link p*, whereby the
valve f, will be raised, and the water allowed to escape; the descent
of the float again permitting the valve f, to fall as long as the bar t,
is heated by the presence of steam, so as to cause the outward end
of the lever q, to be depressed. When the steam has been shut off
from the pipes, and consequently from the box a, the bar t, will of
course become cool, and will therefore contract to its original length,
by which change the end t*, of its slot will act against the inclined
nib of the part s, so as to return the lever q, to the position shown in
the Drawing; and the valve f, will therefore be lifted ready for the
passage of air upon the apparatus being again used, and by which
action also the water remaining in the box a, will be discharged. In
Figs. 4, and 5, I have shown a wire gauge screen applied to the
pipe o, which may be useful in many cases for preventing dirt or other
impurities from entering into the chamber a, so as to interfere with
the correct action of the air-valve.
I have, for the elucidation of my Invention, shown certain arrange-
ment of parts whereby the same may be effected; but I desire it to
be understood that I do not intend to confine myself thereto: that
which I claim as secured to me under the above in part recited Letters
Patent being the adaptation to pipes for warming, drying, or ventilating

page_text: of an apparatus provided with a valve for the discharge of air, such
valve being capable of closing against the exit of steam without the
interference of an attendant.
In witness whereof, I, the said Wright Jones, have hereunto set
my hand and seal, this Eighteenth day of August One thousand
eight hundred and fifty-three.
