1 WILLIAM Cox of 6 Orbel Street Battersea London in the County of Surrey
Tinplate-worker do hereby declare the nature of this invention to be as follows
I first construct a metal case of any required shape and size, by preference of an
oblong form, one end being made deeper than the other, for the purpose of fitting
therein a suitable shaped Bell, Float, or diaphragm; by preference a Bell. Fitted
lengthways into the said case is a balance leaver, on suitable bearings. The said Bell
is attached to one end of the balance leaver by a chain or connecting rod. On the
the other end of leaver is a plain flat valve, fixed rigid to leaver. The inlet pipe is
arranged in such a position that the said valve will close perfectly flat against the
plain flat surface of the inlet pipe. The outlet pipe is arranged in any required
position on the metal case. In the bottom of the said case is a small pipe fixed
perpendicular in such a position as to convey air to the under part of bell or float.
A feeder-screw may be fixed to the case for the purpose of filling with liquid; at a
proper height; so as not to allow of to much being put in.
My Regulator works in the following manner. The Gas enters at the inlet pipe
and if the pressure should increase more than required, the bell or float on one end of
the balance leaver, will be depressed, and consequently the valve on the other end will
be partly closed, thereby closing the inlet pipe to some extent.
The pressure of Gas passing from the outlet, may be varied accordingly,
required, by means of weights on either end of the leaver.

Improvements in Gas Regulators or Governors to Govern the Supply
to one or more Burners.
I, WILLIAM Cox, of No. 6 Orbel Street, Battersea, London, in the county of Surrey,
Tinplate worker, do hereby declare the nature of this invention and in what manner
the same is to be performed, to be particularly described and ascertained in and by the
following statement :-
My Invention has reference to a mode of, and appliance for regulating or governing
the supply of gas to one or more burners, and in order that my Invention may be the
better understood I have appended the accompanying sheet of drawings, referring to
which, Figure 1 is a vertical sectional elevation of my Invention taken on the
line A. B. Figure 2; and Figure 2 is a plan of same.
Figure 1 illustrates an enclosing case A formed of either sheet or cast metal, if of
the latter, one end may be made deeper than the other in order to act as a well for the
reception of the hollow vessel or "bell" hereinafter referred to. At B is an inlet pipe
which is in connection with the meter, and C is an outlet pipe which is connected to
the house delivery pipe. At K Figures 1 and 2 is fixed a partition-the enclosing
case in this instance being made of sheet metal-for the purpose of forming a circular
chamber for the reception of, and within which works freely, the "bell" E, above
referred to, suspended to one end of the lever D, (shown in detail Figures 3 and 4,)
which latter is provided at right angles thereto with a spindle H, (Figures 1 and 3,)
the "knife edge" h of which oscillates upon suitable bearings I fixed to a beam or
cross-head N, (Figures 1 and 2,) which latter serves at the same time to support,
and maintain in position, the inlet pipe B aforesaid. At the centre of the lever D is a
vertical arm (see Figures 1 and 3) to the extremity of which is rigidly fixed a plain
flat valve F, which in its normal position, when the supply of gas is shut off, rests flat
against and closes the inlet pipe B; at. the other end of the lever D is provided a
counterweight G, free to move along the lever, to which it is secured in position, by
means of the screw g, said counterweight being designed for the purpose of determining
the pressure of the gas upon the "bell" E: and, in order to limit the movement of
the lever D, at a predetermined position in the enclosing case A, is fixed a check or
stop d.
In the base of the case A, is inserted centrally, relatively to the "bell" chamber, a
small tube or pipe M Figure 1, open at both ends to allow of the free passage of air
to the upper part of the "bell" E; which latter is provided at the bottom, as shown,
with a cross strap J, having a guide eye j in the centre thereof; and, sliding upon
the small tube M, serves not only as a guide for the "bell," but also very effectually
prevents the vibration so common in Gas governors as hitherto devised.
On the exterior of the case A Figure 1, and in any suitable position, is fixed a feed
pipe L, provided with a screw cap 1, by means of which, water or other liquid can be
introduced into the enclosing case A in order to seal the lower part of the "bell."

page_text: Communicating with the feed pipe L is a passage or channel O, which serves as a trap
for preventing the escape of gas, the orifice o being covered with the liquid contained
in the case; the partition K Figure 1, is also perforated at k to allow of the admission
of the liquid into the chamber surrounding the "bell." The object of the partition K
in the formation of a chamber being to confine the "bell" within as small a space as
is consistent with its free action, as it is found to work more steadily under this
condition than when in a larger chamber; said partition K, would not however be
necessary in the event of the case A being of cast metal, as one part of the enclosing
case A would then be cast deeper than the other, thus forming a well for the reception
of the "bell," and the sealing fluid.
From the above it will be seen, that the ingress of gas into the enclosing chamber A,
exerts a certain influence upon the "bell" E, proportional to the pressure brought to
bear upon it, and consequently upon the valve at the open end of the inlet pipe; thus,
the greater the pressure within the enclosing case, the greater will be the depression
of the "bell," causing in its motion the valve F to approach nearer to the open end of
the inlet pipe, and thereby reducing the supply of gas to the enclosing case A.
Further, said flat faced valve E being disposed in a vertical line relatively to its
bearings, will, notwithstanding the wear of the bearings, always close upon the open
end B of the inlet pipe B at all points simultaneously, without the risk of one part
touching before another.
The cross strap J Figure 1, shown also in dotted lines Figure 2, may if desired be
dispensed with altogether, as it is not essentially necessary to the efficiency and good
working of the apparatus, and when omitted, would render the improved governor
according to my
invention practically frictionless. Further, it is not necessary that
the water or other fluid contained in the "bell" chamber should be maintained at any
given height, as only sufficient is required to well seal the "bell" when at its highest
point, thus the efficiency of the device is not affected by evaporation.
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 :-
:-
Firstly In a gas regulator or governor, the mode of and means for regulating or
governing the supply of gas to one or more burners substantially as herein set forth
and shown in the accompanying drawings.
Secondly-In a gas regulator or governor, the balancing lever D and accessories
in combination with and for operating the "bell" E and plain flat-faced valve F
substantially as herein set forth and shown in the accompanying drawings.
