Improvements in Burners for Hydrocarbon Lamps.
I, JOHN WILLIAM BERNARD WRIGHT, of New John Street West, Birmingham,
in the County of Warwick, Manufacturer, do hereby declare the nature of this inven-
tion 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 Hydrocarbon burners, adapted for use without the ordinary
chimney. Around and enclosing the ordinary wick tube of the burner, I affix a case,
tube, or cone, formed wholly of china, porcelain, or other vitreous or nonconducting
material, or partly of such material and partly of brass or other metal. This outer
case I carry up to a suitable height above the wick case, sufficient space being left
between this and the before mentioned wick case. The top of the outer case is
horizontal. At the bottom of the outer case I provide suitable perforations for the
admission of air, and, near to, and at a suitable distance from the top of the same, I
provide a slot or slots or hole or holes, also for the admission of the outer air. The
effect of this arrangement is that upon the wick being lighted, and allowed to burn
upon the top of the wick case, some distance below the top of the outer case, the heat
generates gas from the oil, which mixes with a current of air passing through the
lower series of perforations. The gas is thus carried upwards through the chamber,
and, assisted by the second current of air admitted through the upper series of
perforations or slots near the top of the chamber, burns with a steady, bright and
clear flame upon the top of the chamber. It is obvious, as above mentioned, that the
outer chamber may be formed either wholly of metal, or wholly of steatite, or of the
two in combination, the porcelain acting as a non-conductor between the brass top
and the body of the burner.
I also, in some cases, dispense with the perforations at the bottom of the chamber.
And in order that my said Invention may be particularly described and ascertained,
reference is hereby made to the accompanying drawings, in which similar letters of
reference indicate corresponding parts.
Fig. 1 is an elevation of my improved burner and Fig. 2 is a section on the line a b
of Fig. 1.
c is the ordinary flat wick tube, having the regulator spindle d fitted thereto, as
usual, for raising and lowering the cotton wick. e is my improved case or cone, the
top of which is horizontal and flattened at the sides, as shewn in section in Fig. 2.
ff are a row of holes formed below the burner, for the admission of air into the case.
These holes are sometimes dispensed with. 9 9 are slots, forming an opening for the
admission of air near the top of the case. Instead of slots, a number of holes may be
made, to answer the same purpose.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, 1 declare that what I
claim is :-
:-
1. In the construction of burners for hydrocarbon lamps, the combination with
the ordinary flat wick tube, of an outer case e, formed with a horizontal top having
slots or other perforations 9 g near the top of such outer case, and with or
without additional perforations ff, substantially as herein before described and
illustrated by the drawings.

page_text: 2. The general construction, arrangement, and combination of the several and
respective parts, together forming my improvements in burners for hydrocarbon
lamps, substantially as herein before described and illustrated by the drawings.
