Improved Means for Regulating the Supply of Gas and other
Fluids or Liquids.
I, JAMES HARMER HAYES, of 40, Saint Charles Square, North Kensington, in
the County of Middlesex, Agent, do hereby declare the nature of my Invention
for "IMPROVED MEANS FOR REGULATING THE SUPPLY OF GAS, AND OTHER FLUIDS
OR LIQUIDS," and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:—
This Invention relates to certain improved means for regulating the supply of
gas, and other fluids or liquids, to burners, meters or where required to be used:
and has especial reference to improvements upon that class of governors in which
the desired regulation is obtained by means of an enclosed chamber, to which the
gas, or other fluid or liquid is admitted from the supply pipe, and from which it is
allowed to escape to the burner, or meter or where required for use, as hereinafter
more fully referred to.
33
For the purpose of the present description, and for the sake of brevity and
distinctness, reference will hereinafter be made solely to "gas" as the medium to
be regulated, and to the " burner as the part to which such medium is desired to
be applied, it being understood that these words are respectively intended to cover
other fluids or liquids, and meters and other places to which the gas, fluids or
liquids are required to be supplied.
Such governors or regulators (those described in the Specification of McLennan
and Owen N° 1055 of 1880 and illustrated in figs. 3 and 4 of the drawings, for
example) have hitherto been constructed with an inner tube or supply pipe
arranged concentrically within the said chamber, and stopped within its own bore,
and formed below and above such stop respectively with inlet and outlet openings
to and from the surrounding closed chamber, and both of which openings have
been under the control of a lever centred between them, and the operation of
which lever is principally dependent upon the respectively constantly varying
pressures within the gas supply pipe, the said enclosed chamber, and the exit pipe
leading to the burner; and is such as to alternately close off the chamber from
communication with the supply pipe, and with the exit pipe, thus at times wholly
closing off the supply of the gas to the said chamber, and permitting only of an
intermittent supply.
Such arrangements and system of operation of necessity require that the means
used for closing off the supply of gas, shall, after each such operation, be again
lifted or removed clear of the inlet opening, to permit of a renewed supply of gas:

page_text: and this is a feature and requirement detrimental to the full utility of such
regulators, as when the pressure of the gas is low, the device or means of closing
the inlet opening is liable to remain closed and not to be removed from closing the
said opening, on account of insufficiency of pressure of the supply, thus preventing
a renewal of the supply and extinguishing or rendering the lights liable to be
extinguished.
An especial object of the present improvements is to avoid the possibility of this
obvious disadvantage occurring, by permitting of the gas being continuously
supplied, and by dispensing with any intermediary regulating chamber between
the inlet and outlet openings and intermittently closed off from communication
with the supply as at present; and to this end, the Invention comprises improved
arrangements and combinations of parts in which the means of regulation are
adjustable and are limited in their action to controlling the escape or supply of the
gas to the burner, and are free from controlling the supply of gas from the supply
pipe.
The Invention also comprises the application of such adjustable means of
regulating the supply to the burner without controlling the inlet of the gas, to
such governors or regulators as hitherto made, in which the special inlet openings
are existent, but will not in accordance with the present improvements be
controlled as formerly.
The Invention also comprises the application to any or all of such regulators of
duplicate adjustable means of regulating the outlet controlling device in accordance
with comparatively high or low pressures of the gas, and with the number of lights
to be supplied, or which may be so set as to permit only of any definite quantity
of gas passing in any unit of time, and an improved formation of the device
controlling the outlet or escape of the gas.
Gas regulating apparatus constructed in accordance with the present improve-
ments, and suitable for application to burners or to pipes leading to groups of
burners, is illustrated on the accompanying drawings, in which. Figs. 1, and, 2,
represent sectional elevations in planes at right angles to each other, of one
modification. Fig. 3, represents a similar view to Fig. 2. of another modification.
Figs. 4, and, 5, respectively represent a sectional elevation, and front view of a
further modification, and Fig. 6, represents a sectional elevation of a still further
modification.
Figs. 1, to, 5, are drawn to a scale of 2 inches to 1 inch of actual size, Fig. 6, is
drawn full size.
The improved apparatus is constructed with a single tube or chamber, 1, into
which the gas freely flows from the supply pipe, (into which the whole attachment
may be simply screwed,) and also with a detachable part, 2, which carries an
adjustable regulating device, 3, together with duplicate and independent adjustable
means, 4, 5, for controlling the same, and is formed with a through outlet opening, 6,
leading to the burner, and can be screwed into or otherwise secured within the
tube, 1, in the manners illustrated, or in any equivalent manner.
3, represents the improved adjustable device for controlling only the said outlet
aperture, 6, and consists of a lever provided with a valve, 7, and screwed at its
depending end and provided with an adjustable counterweight, 8, the lever and its
attachments being centred to and carried by the detachable part, 2, and removable
therewith. The extent of the movements of the controlling device, 3, is regulated,
as desired, in accordance with the pressure of the gas, by means of the duplicate
adjustable wires, 4, 5, which can be set or adjusted, as desired, as hereinafter more
particularly referred to.
The valve, 7, is coned on its inside so that it may be set in relation to the
outlet, 6, for more or less closing the same so as to suit any required number of
burners, or so as to permit of only any required quantity of gas passing in any
unit of time irrespective of the pressure, and is dished or cup shaped on its outer
side so as to be more effectively operated by the pressure of the gas. In lieu of the
adjustable counterweight, 8, and of the lever, 3, the valve, 7, may be adapted with

page_text: a spring, or springs 9, in the manner illustrated in Figs. 4, and, 5, or with
equivalent means, the tendency of which is to keep the valve, 7, open when the
apparatus is not in action, and to cause it to open after being closed, and which,
together with the duplicate means of regulation provided, and which are then
adapted to opposite sides of the springs, 9, cause the controlling lever to be most
delicate and effective for its intended purpose. In the modification illustrated in
Fig. 6, the valve, 7, and spring, 9, are simply adapted to control an outlet aperture
in a disc, 15, the means of regulation, 4, 5, being adapted as in Figs. 4, and, 5.
The duplicate regulating wires, 4, 5, are fitted in coned nuts, 10, carried by the
removable part, 2, and enclosed by the cap, 11, so as to prevent them from being
tampered with after having been properly set, but they may be adapted to work in
any convenient part of the appliance and so that they can be operated from without
the attachment, and the outer heads, 12, of which are squared, as shown, so that
the wires can be turned and their position in relation to the lever, or its equivalent
spring, adjusted with the greatest nicety; the wire, 5, in the modifications illustrated
in Figures 1 to 3 is intended for controlling the lever when working at a high
pressure, and the wire, 4, when working at a low pressure.
In the modification illustrated in Figs. 1, and, 2, the detachable part, 2, is shown
as adapted with a depending extension, 13, which may be directly screwed into the
gas supply pipe, and is also formed to prevent too free a movement to the device, 3.
In the modification illustrated in Fig. 3. the part, 2, is not formed with such
extension, 13, but the bottom cap, 14, is formed so as to screw directly into the gas
supply pipe. The tube, 1, may be cemented into the said caps, 11, and, 14, if
formed of glass, or it may be screwed thereinto if formed of metal, and the said
caps, 11, 14, and their attachments may be variably applied as illustrated.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed, I declare that what
I claim, is
In governors or means of the class hereinbefore indicated for regulating the
supply of gas, and other fluids or liquids, to burners, meters or where required to
be used
1. The application of a combined self adjustable lever and controlling device
limited in its action to the controlling of the outflow of gas to the burner, and
formed, adjusted or adjustable, and regulated as hereinbefore described so as at all
times to leave the inlet or supply of gas open and continuous, substantially as
hereinbefore described.
2. The like application of a combined adjustable spring and controlling device,
limited in its action and operated and operating in like manner, substantially as
herein before described.
3. The application of duplicate adjustable wires or analogous means of regula-
ting the controlling device for high and low pressures, substantially as hereinbefore
described.
4. The novel arrangements and combinations of such parts as hereinbefore
respectively described with reference to the annexed drawings.
