CERTAIN IMPROVEMENTS IN REGULATING THE FLOW OF AIR AND GASEOUS FLUIDS
Year: 1842

page_text: NEWTON'S SPECIFICATION:
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
NEWTON, of the Office for Patents, 66, Chancery Lane, in the County of
Middlesex, Civil Engineer, send greeting.
WHEREAS Her present most Excellent Majesty Queen Victoria, by Her
Royal Letters Patent under the Great Seal of Great Britain, bearing
date at Westminster, the Twenty-fifth day of February, in the fifth year of
Her reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said William Newton, Her especial licence, full power, sole privilege and
authority, that I, the said William Newton, my executors, administrators, and
assigns, and such others as I, the said William Newton, my executors,
administrators, or assigns, should at any time agreo with, and no others, from
time to time and at all times during the term of years therein mentioned,
should and lawfully might make, use, exercise, and vend, within England,
Wales, and the Town of Berwick-upon-Tweed, my Invention of "CERTAIN
IMPROVEMENTS IN REGULATING THE FLOW OF AIR AND GASEOUS FLUIDS," being a
communication from a Foreigner residing abroad; in which said Letters
Patent is contained a proviso obliging me, the said William Newton, by an
instrument in writing under my hand and seal, particularly to describe and
ascertain the nature of the said Invention, and in what manner the same is to
be performed, and to cause the same to be inrolled in Her Majesty's High
Court of Chancery within six calendar months next and immediately after
the date of the said in part recited Letters Patent, as in and by the same,
reference being thereunto had, will more fully and at large appear.
NOW KNOW YE, that in compliance with the said proviso, I, the said
William Newton, do hereby declare that the nature of the said Invention,
and the manner in which the same is to be performed, are particularly described

page_text: and ascertained in and by the following description thereof, reference being
had to the Drawings hereunto annexed, and to the letters and figures marked
thercon (that is to sny) :-
This Invention, which has been conimunicated to me by a certain Foreigner
residing abroad, consists of a peculiar construction of apparatus, in which, upon
the slightest increase of pressure from the air or gas which passes through the
apparatus, the flow of the said nir or gas is restricted and regulated in a novel
manner until the extra pressure has ceased. In order that the Invention may
be perfectly understood, I have shown in the accompanying Drawings various
views of the improved apparatus, whereby the supply or flow of air or gas to
the burners is regulated. Figure 1 is a side elevation of the apparatus com-
plete, and Fig. 2 is a vertical section taken through the middle of the same.
Figure 8 is a horizontal section of the apparatus taken in the line A, B, of
Fig. 2. Figure 4 is a top or horizontal view, the lid or cover being
removed; and Figure 5 is another horizontal section taken in the line C, D, of
Figure 2.
The working parts of the apparatus are contained within the
outside metal casing a, a, a, a, which is supplied with a moveable lid or cover
b. b; an annular moveable bell-shaped vessel c, c, c, c, is placed in the interior
of the metal casing a, a, covering the aperture d, d, by which the gas or air
enters the bell-shaped vessel, and through which its flow or passage is regulated
by means of tho conical end of the hollow tube ff, which is suspended by
means of the metal rod or chain g, from the inside of the bell-shaped vessel c, c.
The aperture d, d, is formed at the upper circular end of the metal cylinder
h, h,h,h; this cylinder is supported by tho annular chamber or gallery i, i, i,i
and when onco placed in its proper situation it remains stationary, and is pro-
vented from moving laterally or out of its position by the small blocks j,j. Tho
apparatus is supplied with water from above by removing the lid or cover b, b, and
its lovel inside is seen by means of the glass tube k, k, outside. All the different
parts of tho apparatus that are to bo filled with water are made to communicate
with each other, the water passing from the upper to the lower part through
the holes 1,1,1,1, seen in Fig. 5, and when the apparatus requires emptying tho
water is allowed to flow out through the aperture m by removing the screw.
The bell-shaped vessel c, c, is suspended by rods or chains n, n, from the ends
of the lovers o, o, and the weight of the vessel c, together with the hollow tubo
ff, is counterbalanced by the weights p, p, at the opposite ends of the levers
o, o. Gas or air flows into the apparatus from the pipe 9, and passes up tho
annular space r, r. r, r, in tho direction of the arrows, and through tho aperturo
d. d, into the upper part of the vessel c, c, from thence it passes down the
annular passaga (, t, and finally escapes from the apparatus through the pipo u.

page_text: If the pressure of the air or gas into the apparatus is too great for the con-
sumption, then it presses on the surface of the water and against the domed
part of the vessel c, c, thereby causing the latter to rise and draw the conical
end e of the hollow tube ff, up into the aperture d, d, and thereby contract the
same and not allow so great a quantity of gas to enter the vessel c, c; when, by
the issue of the gas from the apparatus, the equilibrium or proper pressure is
restored, then the vessel c, c, sinks again and allows the conical end of the
tube ff, to descend also from tho aperture d, and permit the gas to enter the
apparatus as before.
Having now described the Invention that has been communicated to me, I
wish it to be understood that I do not intend to confine myself to the precise
forms of parts heroin shewn, nor to the materials of which the same is to be
composed. But I claim, as the Invention secured to me under the herein-before
in part recited Letters Patent,-
First, the peculiar arrangement of apparatus herein shewn and described, or
any modification thereof; and
Secondly, any apparatus for regulating the flow of air or gas in which such
regulation is effected by means of a conical plug, or the conical end of a tube,
either hollow or solid, rising into the aperture through which the gas passes,
and thereby closing or partially closing the same, and proventing the air or gas
from passing, as above described.
In witness whereof, I, the said William Newton, have hereunto set my
hand and seal, this Twenty-third day of August, in the year of our
Lord One thousand night b
WILLIAM (L.B.) NEWTON.
AND BE IT REMEMBERED, that on the Twenty-third day of August,
in the sixth year of the reign of Her Majesty Queen Victoria, the said
William Newton came before our said Lady the Queen in Her Chancery,
and acknowledged the Instrument aforesaid, and all and every thing therein
contained and specified, in form above written. And also the Instrument
aforesaid was stamped according to the tenor of the Statute made in the
fifty-fifth year of the reign of His late Majesty King George the Third.
Inrolled the Twenty-fifth day of August, One thousand eight hundred
and forty-two.
