PROVISIONAL SPECIFICATION.
Improvements in Atmospheric Gas Burners.
I, THOMAS REDMAN, of the Priory, Bolton, Bradford, Yorkshire, Gas Engineer,
do hereby declare the nature of this invention to be as follows:-
My invention relates to certain improvements in atmospheric gas burners,
such as are used in connection with incandescent mantles, and has for its object
the arrangement of some portions of the burner in order that the gas is more
effectually consumed and a greater amount of luminosity obtained with the gas
consumed than is the case with burners constructed as hitherto.
In order to obtain my object, I employ a bunsen tube such as is now used
in connection with what is commonly called the Welsbach C, incandescent
burner," which in addition to the usual perforations at the base of the tube, I
perforate the neck or narrow part of the tube which receives the burner top.
A portion of the said tube around the additional perforations is preferably
reduced in order to facilitate the reduced portion of the stem of the tube to be
indented inwards and thus form perforations somewhat conical with internal
projections or lips pointing upwards, by the introduction of which the gas and
air are more thoroughly amalgamated.
The top portion of the burner is covered with gauze or a perforated plate as
hitherto, but to more completely consume the mixture of gas and air I place
in the centre of the gauze or perforated plate a cone or curved cap arranged in
a manner that, the flame is diverted so as to act with greater effect on the mantle
and thus give a better light with the same amount of gas consumed than is
obtained with burners of the ordinary construction.

Improvements in Atmospheric Gas Burners.
I, THOMAS REDMAN, of the Priory, Bolton, Bradford, Yorkshire, Gas 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 relates to certain improvements in atmospheric gas burners,
such as are used in connection with incandescent mantles, and has for its object
the novel arrangement of some portion of the burner, so that gas and air are
more thoroughly amalgamated in order that the mixture may be more effectually
consumed and a greater amount of luminosity obtained with a given quantity
of gas than is the case with burners constructed as hitherto.

page_text: In describing how my invention may be carried out, reference is made to the
accompanying drawings marked with letters of reference.
Fig. 1, represents a sectional elevation of a burner constructed in accordance
with my invention, and
Fig. 2, a cross section through line a, b, and drawn to an enlarged scale.
In order to obtain my object I utilize the ordinary bunsen burner tube, one
portion of which at A is larger in diameter than the other as shown at A', the
same tube being such as is now used in connection with what is commonly
called the "Welsbach C. incandescent burner."
The larger diameter or base A, of the tube is perforated at B, in the usual
manner, and above the said base in the narrow or neck part A of the tube I
form perforations at C and the remaining upper portion of the said neck or tube
receives the burner head D.
At the under side of perforations C, the tube A¹ is indented forming projec
tions A, somewhat conical in shape as shown in both Figs. 1 and 2, by the
introduction of which the flow of gas and air admitted in the usual manner are
diverted in their straight upward course, thereby agitating the same in a manner
to more thoroughly amalgamate the same and with the air admitted through the
additional and conical shaped openings C.
To the top of the tube A¹ is attached the burner head D, the upper surface of
which is covered with a gauze, perforated or serrated plate P as hitherto, but
to more effectually consume the mixture of gas and air, I place in the centre
of the burner top and above the gauze or the like a circular plate E of a suitable
diameter, such as for example of a diameter equal or thereabouts to that employed
on the Welsback C burner as at present constructed.
A part of the underside of my circular plate is arranged with a straight or
curved face inclining upwards and outwards instead of flat as hitherto, by which
the flame is diverted and made to more effectually impinge upon the mantle M
supported above the burner in the usual manner, and thus heat the mantle to
a greater temperature thereby giving a better fight with the amount of gas
consumed than is the case with atmospheric gas burners of the ordinary con-
struction.
In order to ensure the supply of air through the additional perforations C,
the tube A¹ may be beaded above the perforations C upon which an ordinary
back flash plate G may rest as shown by Fig. 1, or the said plate may be supported
in any convenient manner.
I find by experimenting the best results are obtained by using the burner as
described with a chimney, but beneficial results may be obtained without a
chimney and when the burner is used in this manner the cover or plate E must
be removed also.
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. An atmospheric gas burner having a bunsen tube of two diameters A
and A each portion perforated combined with a gauze or the like covered
burner top P and provided with a cover or deflecting plate E the whole arranged
substantially in the manner and for the purpose as herein before set forth and
illustrated.
2. An atmospheric gas burner bunsen tube comprising a tube perforated
at B and C with conical shaped indentations as at A2 as herein before set forth
and illustrated.
