Improvements in Self-regulating Gas Burners.
WILLIAM THOMAS SUGG of Vincent Street in the City of Westminster,
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:-
This invention relates to that class of self-regulating gas burner in which a
steatite float governor is enclosed in a metal case, which also carries the jet, and
the object of the invention is to improve the construction of these burners,
whereby certain disadvantages of the present construction are obviated; also to
simplify the construction and to reduce the cost of production.
Hitherto, the steatite float has been placed directly into the metal case, which,
when it becomes hot, under the influence of the burning gas, expands, leaving
more or less space between it and the float, which does not expand, at any rate not
at the same ratio, and thus the gas can pass to the jet round the edge of the float,
and the governor is not effective.
In carrying out my invention, I interpose between the float and the case, a
cylindrical cap of steatite, which I fix in the case in such a manner that the gas
cannot pass between it and the case, and as the two steatite portions will expand
and contract, if at all, at the same ratio, the gas will be obliged to pass through
the float, and thus be properly governed.
The steatite for the cap and the float are both unbaked, and consequently there
is complete lubrication, and no fear of sticking.
In the accompanying drawing, I have shown, at Fig. 1, in sectional elevation,
the simplest form of governor burner constructed according to my invention, and
at Fig. 2 a slight modification.
A represents the metal case, and A¹ a steatite cover, which is formed in one
with the jet B, and is made to fit into the part A, which contains the governor.
The part A is formed with a threaded stem, and, as will be seen, is of two
diameters internally. In the smaller diameter is fixed, by means of a little red
lead at the bottom edge, or in any other convenient manner, the steatite cap, or
small gas holder or cylinder C, having preferably, at one side, an elongated opening
into the space between the cap C and the larger diameter of the case A.
The same effect will of course be produced by making the case of the same
diameter internally, and the cap of two diameters externally.
Inside the cap C is placed the steatite float governor D, of the usual
construction, having an opening of the proper size in the top. E is a disc of
gauze, which serves to break up the flow of gas, and prevent noise.
In the modification Fig. 2, the part A' is made of metal, and carries at its upper
end the jet B. In this case, the part A¹ fits tightly onto the part A.
By constructing the burner as above described, the cost of production is
reduced principally by the saving in the wear of the tools required in the
manufacture, but also in time, as the degree of accuracy generally in the metal
work bitherto required, is not of so much importance, and consequently cheaper
and quicker methods of production may be employed, the only parts in which
complete accuracy is positively required being the internal diameter of the cap
and the external diameter of the float.

page_text: Having now particularly described and ascertained the nature of the said
invention and in what manner the same is to be performed, I declare that what
I claim is :-
1. The construction of self-regulating gas burner as herein shown and described.
2. In a self regulating gas burner, enclosing the steatite float in a steatite cap
or cylinder, which is fixed in the metal case, as and for the purposes set forth.
