Improvements in Gas Burners.
A communication from JAMES SMITH, of 399, Richmond Street, London, in the County
of Middlesex and Province of Ontario, Dominion of Canada, Hotel-keeper,
and HARRY JAMES BOYD, of 196, Dundas Street, London, in the County of
Middlesex and Province of Ontario, Dominion of Canada, Manufacturer.
I, ALFRED JULIUS BOULT of 323 High Holborn, in the County of Middlesex,
M.I.M.E., 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 :—
Our invention relates to burners designed for heating purposes and consists of a
conical tube constructed with a small expanding flange at one end and a larger
expanding flange at the other end, and the supply tip of gas pipe is enclosed in this
burner. The smaller flange is usually made with corrugated sides and the larger
one is usually constructed with perforations in its surface and surrounded by a
perforated metal shell which may be turned round so as to cover or leave open the
perforations in the flange and thereby check or accelerate the volume of the flame
issuing from the burner. The lower part of this flange may also be fitted with a
circular screen of wire gauze which will wholly enclose the lower part of the burner
and while admitting air freely, will prevent the flame from being extinguished by
any sudden draught.
In the accompanying drawings of our invention;-Fig. 1 is an elevation and
Figure 2 a central vertical section.
A is the central part of burner and B the expanding flange at the smallest end
through which the flame from supply tip C issues. This flange is usually corrugated
as shown but it may also be made with plain sides.
D is the expanding flange in which the larger end of the burner terminates. The
sides of this expanding flange are usually perforated so as to admit air from the
side and thereby decrease the direct draught from below.
E is a covering shell also perforated and fitting outside or inside the flange D and
this perforated shell is constructed so as to turn partly round and thus cover or
expose the perforations in the flange D and thereby regulate the draught to the
burner.
F is a circular screen of wire gauze having the bottom also filled in with wire
gauze an opening being left therein through which the supply tip C passes. This
gauze screen protects the flame from being extinguished by outer draughts.
The air passes into the burner through the wire gauze screen, and is fed to the
flame issuing from the supply tip C in the burner. The expanding flange D at
largest end of the burner causes a greater volume of air to be drawn into the burner,
and the smaller expanding flange B causes the flame issuing from it to pass out in
a broader form than it would otherwise do. This flange B may be made with plain
sides, but when corrugated as shown it is prevented from getting out of shape or
becoming over-heated.
Having now particularly described and ascertained the nature of the said invention
and in what manner the same is to be performed, as communicated to me by my
foreign correspondents, I declare that what I claim is :-
1. As an attachment to gas supply tips a conical tube having a small expanding
flange B formed on or attached to the small end of said conical tube, and a larger
expanding flange D formed on or attached to the largest end of said conical tube the
whole enclosing the gas supply tip substantially as shown and specified.

page_text: 2. As an attachment to gas supply tips a conical tube the smallest end of which
terminates in a small expanding flange the sides of which are corrugated and the
largest end terminates in a larger expanding flange the sides of which are per forated
and fitted with a movable perforated shell E for the purpose of closing or opening the
perforations in the flange substantially as shown and specified.
3. In combination with a conical tube having a small expanding flange at one end
and a larger expanding flange at the other end, the gauze wire screen F through
which the gas supply tip is admitted to the interior of the burner substantially as
shown and specified and for the purpose set forth.
