ALFRED HALEY of 52 Ashburton Grove Holloway and ALICK CLAUDIUS SAVAGE
of 1 Pleasant Row Canonbury in the County of Middlesex. AUTOMATIC
APPARATUS FOR REGULATING THE SUPPLY OF GAS OR OTHER FLUID
In Gas Regulators as hitherto constructed the regulation has chiefly been effected
by the pressure of the Gas in its passage to the Burners acting upon a membraneous
diaphragm, or by the pressure of the Gas raising an inverted cup out of a trough
of mercury or other liquid, whereby the variation of pressure causes a valve or
valves to diminish or increase the area of the opening or openings by which Gas
is supplied to the Burners and thus to proportionately regulate the quantity of
Gas passing. Now as at present constructed it will be perceived that as increasing
pressure diminishes the area of the opening or openings by which gas is admitted
to the burners it also diminishes the supply necessary to actuate the regulating
medium such as the membraneous diaphragm or inverted cup before mentioned.
The object of our Invention is to remedy this defect by rendering the opening
through which the gas is admitted to the regulating medium independent of the
valve thus ensuring the quantity being invariable.
We now proceed to describe one method of accomplishing the same.
In a suitably shaped chamber formed in the upper part of a body or casing
provided with the necessary inlet and outlet openings we place a diaphragm bag,
or container composed of prepared leather or other suitable material the said
diaphragm, bag, or container being capable of becoming inflated or distended by

page_text: the increasing pressure of the gas or other fluid entering therein or of collapsing as
the pressure of the gas or other fluid decreases; air aloue being admitted into the
aforesaid chamber. Into the bottom of the said chamber to which the diaphragm,
bag, or container before mentioned is attached we fix a tube projecting into the
inlet opening beneath through which gas is admitted into the enclosure formed by
the said diaphragm bag, or container. On the outside of the said tube a conical,
ball, or half ball valve is made to slide freely against a corresponding seating formed
by an aperture conveniently placed between the inlet and outlet openings. The
said valve is suspended to the diaphragm, bag, or container already mentioned,
with the movements of which it acts in unison by a small rod passing through
the interior of the tube on which it slides.
In order that the aperture against which the valve acts may be of the required
area it is made proportionately larger to allow for the space occupied by the said
tube passing through it.
We regulate the quanity of Gas admitted to the Burners by opposing to the
pressure of the Gas inside the diaphragm, bag, or container the resistance exerted
by an adjustable spring or weights on the outside thereof.
In the case of Regulators where the varying pressures of the Gas or other fluid
causes an inverted cup to rise and fall in a trough of mercury or other liquid
thereby causing a valve to increase or diminish the size of the opening through
which gas is supplied to the Burners the application of our Invention will readily
suggest itself from the foregoing description.

ALFRED HALEY of 52 Ashburton Grove Holloway and ALICK CLAUDIUS SAVAGE
of 1. Pleasant Row, Canonbury, in the County of Middlesex AUTOMATIC APPARATUS
FOR REGULATING THE SUPPLY OF GAS OR OTHER FLUID
In Gas Regulators as hitherto constructed the regulation has chiefly been effected
by the pressure of the Gas in its passage to the Burners acting upon a diapraghm
or by the pressure of the Gas raising an inverted cup out of a trough of mercury
or other liquid whereby the variation of pressure causes a valve or valves to
diminish or increase the area of the opening or openings by which gas is supplied
to the Burners. Now as at present constructed it will be perceived that as
increasing pressure diminishes the area of the opening or openings through which
Gas is admitted to the Burners that besides lessening the supply to the Burners it
also diminishes the supply necessary to actuate the regulating medium such as the
diapraghin or inverted cup before mentioned
The object of our Invention is to remedy this defect by rendering the opening
through which the Gas is admitted to the regulating medium independant or
separate from the opening through which the main supply passes to the Burners so
that while the area of the opening leading to the Burners is variable the area of
the opening leading to the regulating medium is invariable and also to make the
action more reliable and effective in case of membraneous diapraghms by causing
the gas to pass into an enclosure and so inflate or distend a diapraghm bag, or
container instead of the regulation being effected by simply raising or deflecting a
diapraghm to which the valve is attached. This we accomplish as follows.
In a suitably shaped chamber formed by a hollow cover screwed on to the upper
part of a body or casing provided with the necessary inlet and outlet openings we
place a diapraghm, bag, or container composed of prepared leather or other suitable
material the said diapraghm, bag, or container being capable of becoming inflated
or distended by the increasing pressure of the Gas or other fluid entering therein
or of collapsing as the pressure of the Gas or other fluid decreases. Into the
interior of the said Chamber air alone may be admitted in which case suitable air
holes are provided in the cover; or Gas, the pressure of which has been regulated
may be adinitted through a tube or channel leading from the outlet side of the
apparatus in which case air holes are not needed. Into the upper part of the
before mentioned body or casing which also forms the bottom of the chamber
aforesaid we fix a tube leading into the enclosure formed by the diapraghin bag or
container and projecting into the inlet opening beneath. On the outside of the
said tube a conical, ball, or half ball valve is made to slide freely against a
corresponding seating formed by an aperture conveniently placed between the
inlet and outlet openings the said valve being suspended to the diapraghin bag
or container already mentioned with the movements of which it acts in unison by
a small rod passing through the centre of the tube on which it slides.
It will be evident that in operation Gas enters into the enclosure formed by the
diapraghm, bag, or container through the tube already described and by its
varying pressure expands or contracts the same thereby causing the valve suspended
to it to diminish or increase the area of the opening through which the main supply
passes to the Burners.
In order that the aperture against which the valve acts may be of the required
area it is made proportionately larger to allow for the space occupied by the said
tube in passing through it.

page_text: We regulate the quantity of Gas admitted to the Burners by opposing to the
pressure of the Gas inside the diapraghm bag, or container the resistanc eexerted
by an adjustable spring or weights on the outside thereof.
Having now described the nature of our Invention and the manner of carrying
it into effect we wish it to be understood that we do not restrict ourselves to the
precise details herein described but what we believe novel and original is.
1st The mode or method of introducing the Gas to actuate the regulating
medium separately and independantly of the supply to the Burners
2nd The admission of the regulated Gas from the outlet side of the apparatus
to the diapraghm chamber thus dispensing with air holes in the cover and avoiding
the risk of escape of Gas should there be leakage through a defective diapraghm
bag or container
In witness whereof we the said Alfred Haley and Alick Claudius Savage
have hereto set our hands & seals this thirty first day of January in
the year of our Lord One thousand eight hundred & eighty three.
