Improvements in Gas Regulators or Governors.
ROBERT ROYON BEARD 57 Fort Road Bermondsey London S.E. Engineer, do
hereby declare the nature of this invention to be as follows :-
:-
My invention has for its object new or improved means for automatically controlling
the flow and pressure of gas.
My invention is particularly applicable to gas regulators where a chamber or bellows
is moved or lifted according to the pressure of the gas within the chamber or bellows
such chamber or bellows by moving causing a valve for admitting the gas into the
chamber or bellows to open or close according to the direction the chamber or bellows
is moved.
For the purposes of my invention I use a series of levers or rods jointed together
in the form known as lazy tongs one end or ends of the series of levers being con-
nected to the movable chamber or bellows the other end or ends of the series of levers
terminating in eccentrics which move or oscillate on a pin fixed to the frame of the
regulator or to a portion of the regulator other than the movable chamber or bellows.
The eccentrics press on or are connected to the valve for admitting gas into the
movable chamber or bellows.
Instead of eccentrics cog or bevelled wheels may be used to move the valve for
admitting gas into the movable chamber or bellows suitable counterpart cogs or
bevelled wheels being in this case adapted respectively to the valve for admitting gas
into the movable chamber or bellows also instead of eccentrics portions of the series
of levers may press directly or be connected to the valve for admitting gas into the
movable chamber or bellows.
The movable chamber or bellows is pressed by a spring or weight against the
pressure of the gas as it is usual with gas regulators.
The regulator has a suitable fitting for connecting to a gas supply such fitting com-
municating by a suitable passage for the gas with the seat of the valve for admitting gas
to the movable chamber or bellows and from the said valve to the movable chamber or
bellows. There is also a suitable exit from which the gas is taken for use communi-
cating with the movable chamber or bellows.
The gas in passing from the gas supply through the before mentioned valve into the
movable chamber or bellows inflates the movable chamber or bellows which being fixed
to the series of levers causes the series of levers to move and thus cause the occentrics
or other before mentioned arrangements to press or move the before mentioned valve
towards its seat thus checking the flow of gas from supply.
When the gas is allowed to flow from the before mentioned exit according to
requirements the escape of gas from the movable chamber or bellows permits the spring
or weight on the movable chamber or bellows to force it back and thus cause the before
mentioned valve to open sufficiently according to the flow of gas from exit. When
the exit is closed the movable chamber or bellows is inflated until the before mentioned
valve is completely shut.
Several valves may be used & several movable chambers or bellows if desired and
where very fine regulation is required one regulator may be made to regulate another
regulator by passing the gas froin one regulator to another.

Improvements in Gas Regulators or Governors.
I ROBERT ROYON BEARD of 62 Alscot Road late of 57 Fort Road Bermondsey
in the County of Surrey Engineer 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 for its object. Improvements in Gas Regulators or Governors and
is particularly applicable when the Gas is supplied at a high pressure and is required to
be used at a low pressure such for instance as oxygen or hydrogen gas issuing from
high pressure tubes for lime light arrangements.
The drawings hereunto annexed illustrate the method which I prefer to use in
carrying my invention into effect.
Figure I is an elevation of the whole arrangement.
Figure II is an enlargement of those parts which operate upon the Valve.
Figure III is a side view of the eccentrics and of their mode of action.
The Gas at high pressure is introduced through the tube A and is required to issue
through P at a low and regular pressure B is a metal valve operating upon a seating
at the top of A and capable of completely closing the aperture. Cis a rod to which
the valve B is attached and works in the tube conveying the Gas after it has passed
through the valve B. D is a frame to the underpart of which the rod C is fastened
and which as it rises or fails opens or closes the valve B. E represents two eccentrics.
working on a common centre spindle F which is permantly fixed in the framework G.
The rotation of the eccentrics causes the frame D to rise or fall and so operate on the
valve B. H. H is a tube of india rubber or other elastic material having a bellows
motion as shewn in Figure I. H. H is fastened to the casing K and to the metal
Cap L which allow of expansion or retraction according to the pressure of gas
admitted through the valve B. M. M. are levers arranged in the form of lazy-tongs
which are fastened as shewn into the cap L and which acting upon the eccentrics E
cause when the cap L is raised the frame D to fall and thus to close the valve B.
It will be seen from the above arrangement that the greater the pressure of gas
admitted through Binto the regulator the tighter B will be closed and that if the
"pressure is reduced the cap L will fall and more gas will be introduced through B.
The entire regulator is fastened into an outside cover N substantially as shewn in
Figure 1 O is a spring working upon the cap L and within the cover N the strength
of which Spring should be regulated according to the pressure at which it is desired
to use the Gas. It is obvious that the stronger the spring O is the greater will be the
pressure at which the Gas will be emitted at the exit P.
Figure IV illustrates a modification of the arrangement which in some cases may
be deemed desirable I have there substituted a cog arrangement Q in place of the
eccentrics and frame E and D in Figure II. It will be observed in Figure 4 that
the movement is imparted to the valve on each side of the spindle and that the same
remark applies to the movement imparted by the eccentrics in Figures 1. 2. and 3. I
have ascertained by experience that this is an important factor in obtaining regularity
of pressure.
Having thus explained and described the nature of my Invention and the manner
in which the same should be performed I wish it to be. understood that what I
¡claiin is
Firstly. The arrangement and combination of the levers M with the cap L and the
bellows tube H the eccentrics E (or in substitution for such eccentrics the cog arrange-
ment Q) with the valve B substantially in the manner and for the purposes herein-
before described. ... .L.
Secondly. The application of the levers M arranged as lazy tongs to gas regulating.
