Improvements in Lamp-burners for Burning Hydrocarbon Oils.
I, JAMES MAOMILLAN ROWATT, of the firm of Thomas Rowatt & Sons, of
9, 10, 11 and 12, Radsworth Street, City Road, in the County of Middlesex, and of
126, Fountain Bridge, Edinburgh, in the County of Midlothian, Lamp Manufacturers,
do hereby declare the nature of this invention to be as follows:-
My invention relates to improvements in burners for burning paraffin oil,
petroleum, and other hydrocarbon oils.
In carrying out my invention I use three or more flat wick tubes placed parallel-
wise. In the case where I use three tubes only I make the centre one wider than
the two outer ones. In some cases the two latter may be somewhat curved instead
of flat.
Where I use more than three wick-tubes, say five, for example, the centre one is
made wider than the others.
Either a chimney or a globe can be used with my improved burner the cone or
body of the burner being arranged as required to draw sufficient oxygen for the
purpose of producing good combustion, and either one or two domes or cones can be
used for the purpose of deflecting the oxygen onto the flames.

I, JAMES MACMILLAN ROWATT, of the firm of Thomas Rowatt & Sons, of
9, 10, 11 and 12 Radsworth Street, City Road, in the County of Middlesex, and of
126 Fountain Bridge, Edinburgh, in the County of Midlothian, Lamp Manufacturers,
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 improvements in burners for burning paraffin oil,
petroleum, and other hydrocarbon oils.
In order to enable my invention to be fully understood I will proceed to describe
the same by reference to the accompanying drawing in which Figuro 1 is a plan,
and Figure 2 a vertical section of a burner provided with three wick tubes arranged
according to my invention and adapted to be used with a chimney; Figure 3 is a
plan of a similar burner having five wick tubes; Figure 4 is an elevation of a burner
similar to that shown in Figures 1 and 2, but arranged to receive a globe instead of
a chimney. Similar letters in all the figures represent similar parts.
In carrying out my invention I use three or more flat wick tubes placed parallel-
wise. In the case where I use three tubes only, as shown in Figures 1, 2 and 4, I
make the centre tube a wider than the two outer ones b, b. In some cases the two
latter may be somewhat curved instead of being quite flat.
When use more than three wick tubes, say five for example, as shown in
Figure 3, the centre tube a is made wider than the two adjacent tubes b, b which
latter are wider than the outer tubes c, c.
Either a chimney or a globe can be used with my improved burner, the cone or
dome d of the burner being arranged as required to draw sufficient oxygen for the
purpose of producing good combustion.
In Figures 1, 2 and 3, the dome or body of the burner is shown as arranged to be
used with a chimney e while Figure 4 shews the burner arranged to be used with a
globe. In the drawing only one dome dis shewn for the purpose of deflecting the
oxygen onto the flames but if required two domes can be used.
The other parts of the lamp burners being of ordinary construction need no
description.
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 1
claim is
The manufacture and use of the improved lamp burners hereinbefore described
and illustrated in the accompanying drawing.
