Improvements in Gas Burner Regulators.
I, WILLIAM BEAL, of Hill Street, Birmingham, Warwickshire, Lamp and Gas
Fitting Manufacturer, 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:-
This invention relates to that class of regulators which are combined with illuminating
gas burners for the purpose of automatically regulating and controlling the flow of
gas to the burner and it consists firstly, of an improved and simplified construction
of gas burner regulator and secondly in the provision of means by which the action of
the internal mechanism of gas regulator burners generally can be seen when the
burner is in use.
In the accompanying drawings Fig. 1 represents in front elevation, Fig. 2 in plan,
Fig. 3 in sectional elevation and Fig. 4 in sectional plan, a gas burner regulator
constructed according to my invention; Fig. 5 is a sectional elevation of the same as
it would appear when regulating the flow of high pressure gas to the burner;
Figs. 6, 7, 8 and 9 represent details of the same as hereinafter fully described.
In these Figures like letters indicate corresponding parts.
I provide an outer shell or case consisting of a hollow upper part a into which the
gas burner is screwed or otherwise secured, and a lower part c which is screwed or
otherwise formed for attachment to the gas supply and has an inlet hole c'. The
upper part a and the lower part care screwed or otherwise connected together.
Fitting loosely within the said outer sheel or casing is a regulating valve d which is
preferably of the form shewn, that is a hollow cylinder closed at the top with a dome-
shaped head. The valve d can move up and down inside the outer casing through a
short space and when in its lowest position it stands upon the lower part c (see Fig. 3)
and when in its highest position its dome-shaped head fits against a diminished circular
part or seating a of the upper part a (see Fig. 5). Extending upwards along the
outside of the valve are small grooves e preferably four in number (but a greater or
smaller number of grooves may be used according to their size and the size of the
burner) and at the bottom of each groove is an indentation which when the valve is
in its lowest position (see Fig. 3) form communications from the inlet hole c¹ to the
grooves e.

page_text: The operation of the gas regulator burner as above in part described is as follows:-
When the gas is flowing to the burner at so low a pressure that the regulator is not
*required then the valve d. remains on the lower part c (as the pressure of the gas is
not sufficient to raise it) and the gas flows through the indentations and along the
grooves e to the burner. The valve d is made of such a weight that it will be raised
by the pressure of the gas when that has increased to such an extent that the burner
is passing more gas than it is constructed to burn; the valve then rises and comes in
contact with the valve seating a¹ and cuts off the supply of gas to the burner except
what passes through grooves e which at the point where the valve d comes in contact
with the valve seating a are considerably diminished in area thus automatically
checking any increased flow of gas to the burner. By increasing or diminishing the
size or number, or the size and number of the grooves e and the weight of the valve d
the regulator can be arranged for any size of burner.
It will be evident that the construction and arrangement of the parts may be
modified in many ways without departing from the nature of my invention, for
instance as shewn in the burner represented in sectional elevation and in plan by
Fig. 10 where grooves g are cut along the inner side of the upper part a instead of
the grooves e in the valve d which latter is made plain (or it may be grooved also).
The grooves are so small where they cross the valve seat a that when the high
pressure of the gas has forced the valve against its seating a¹ they will allow only the
proper amount of gas to pass through the burner.
In order that the action of the valve d may be visible when the burner is lighted I
make the outer casing of a glass tube a fitting on to a lower metal part c and an
upper metal part a (see Fig. 11) the glass tube being secured to the parts a and c by
cement or other means and the whole fixed together by the wires h, h, which pass
through holes in the parts a² and c where they are fixed preferably by nuts or by
being soldered thereto. A scale may be engraved or otherwise fixed on or near the
glass part a² which will shew the height of the valve d and indicate the
pressure of
the gas. The transparent outer casing above described and illustrated by Fig. 11 can
be modified without departing from the nature of my invention, for instance its upper
part a and wires h, h, may be dispensed with and the burner fixed directly to the
glass part.
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 :
1st. A gas burner regulator consisting of an outer casing and an internal valve d
both constructed arranged and the valve d operating substantially as hereinbefore
described with reference to and shewn in the accompanying drawings.
2nd. In gas burner regulators the application and use of a transparent outer casing
for the purpose and substantially as described with. reference to Fig. 11 of the
accompanying drawings.
3rd. A transparent outer casing for a gas burner regulator constructed substantially
as hereinbefore described, and illustrated by Fig. 11 of the accompanying drawings.
