PROVISIONAL SPECIFICATION.
Improvements in Oil Lamps.
I, CHARLES DIXON ARIA, of 175, Piccadilly, London, Lamp Manufacturer, do
hereby declare the nature of this invention to be as follows:
--
My invention relates to lamps and specially to the burners, of the kind referred
to in my former Letters Patents Nos. 16073 of 1887 and 15768 of 1888, and it has
for its object to so construct the burners therein described as to render the same
more compact and shorter, while at the same time to better direct the air currents
and thereby to promote more perfect combustion.
According to my present improvements the skeleton frame or support described
in the Specifications of the abovementioned Letters Patents is now replaced by a
perforated annular support or ring which is so arranged as to encircle the upper
portion of the secondary reservoir, thus reducing the length of the burner.
Fitting over the upper part of this perforated annular support or ring is a cone
of ordinary construction which is necessary when the burner is to be applied to
lamps other than carcel or moderator. This support or ring is provided at its
lower part with holes or orifices to allow any overflow of oil from the secondary
reservoir to escape, and if preferred to be received into a drip cup which may be
arranged at the bottom of such secondary reservoir.
The wick tube is carried by a foraminous disc or plate fitting into the upper part
of the perforated annular support or ring, and this disc or plate may also carry the
winding spindle and its toothed wheels or pinions for raising or lowering the wick.
When a single wick is employed the central air tube mentioned in Letters Patent
No. 15768 of 1888 may be replaced by two air tubes, say of arc shape in cross
section, between which the wick and the lower portion of the wick tube or case
depend, whereby the wick and the surrounding parts are kept cool.
With duplex or with triple burners the air tube is centrally arranged, as
described in the Specification of Patent just above referred to, and the wicks are
arranged about or around the same.
Dated this 10th day of Jin 1890.

COMPLETE SPECIFICATION.
Improvements in Oil Lamps.
I, CHARLES DIXON ARIA, formerly of 175, Piccadilly, but now of 2, Duke
Street Mansions, Duke Street, Grosvenor Square, in the County of Middlesex,
Lamp Manufacturer, 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 lamps of the kind referred to in the Specification of
former Letters Patent granted to me Nos. 16073 of 1887 and 15768 of 1888 and it
has for its object to so construct the burners of that class of lamp as to render the
same more compact and shorter and capable of burning flat wicks whilst at the
same time to better direct the air currents and thereby to promote more perfect
combustion.
According to my present improvements the skeleton frame or support described
in the Specifications of the above mentioned Letters Patent is replaced by a

page_text: perforated annular support or ring which is so arranged as to encircle the upper
portion of the secondary reservoir thus reducing the length of the burner and
fitting over the upper part of this perforated annular support or ring is a cone of
ordinary construction.
Any overflow of oil from the secondary reservoir is received into a drip cup
which is arranged at the bottom of such secondary reservoir.
The wick tube is carried by a foraminous disc or plate loosely fitting into the
upper part of the perforated annular support or ring and this disc or plate also
carries the winding spindle and its toothed wheels or pinions for raising or lowering
the wick.
This support or ring is perforated or provided with holes or orifices in order to
allow a current of air to pass between the secondary reservoir and the perforated
plate or disc and to circulate around the wick tube or tubes thus assisting to keep
cool those parts and consequently the oil in the secondary reservoir and at the same
time aiding the combustion of the flame.
When a single wick is employed the central air tube mentioned in Letters Patent
No. 15768 of 1888 may be replaced by two air tubes say of arc shape in cross
section between which the wick and the lower portion of the wick tube or case
depend whereby the wick and the surrounding parts are kept cool.
With duplex or with triplex burners the air tube is centrally arranged as
described in the Specification of Letters Patent lastly hercinbefore referred to and
the wicks are arranged about or around the same.
And in order that the said invention may be more clearly understood and readily
carried into effect I will proceed aided by the accompanying drawings more fully
to describe the same.
DESCRIPTION OF THE DRAWINGS.
Figure 1 is an elevation partly in section of a flat wick reading lamp constructed
according to my invention.
Figure 2 is a vertical section of the burner separately.
Figure 3 is a vertical section taken at right angles to Figure 2.
Figure 4 is a plan with some of the parts removed.
Figure 5 is an underside view of the lower part of the burner separately with
the regulating cap removed.
Figure 6 is a similar view with the regulating cap in position and
Figures 7, 8, and 9 are similar views to Figure 4 but showing the method of
arranging the wick tubes in duplex and triplex burners.
In the several figures in which like parts are indicated by similar letters of
reference Figure 1 is drawn to a reduced scale whilst the remainder of the figures
are drawn the actual size.
Referring to Figures 1 to 6 a** represents the main reservoir or oil container,
a represents the secondary reservoir and a* represents a perforated annular support
or ring which is substituted for the skeleton frame or support shown and described in
the Specification of the Letters Patent herein before referred to and is so arranged
as to encircle the upper portion of the secondary reservoir a and the length of the
burner is thereby materially reduced thus rendering the same more compact and
this annular support or ring a* which forms part of the burner body supports
upon its upper edge a cone of ordinary construction.
Any overflow of oil from the secondary reservoir a is received into a drip cup a¹
provided upon the exterior of the secondary reservoir a.
The wick tube c¹ is carried by a perforated plate or grating c which forms an air
distributor and fits loosely into the upper part of the annular support or ring a*
and the wick tube c¹ receives an additional support from a bracket c* whilst the plate
or grating also carries the spindle d of the wick raisers d'.
C
The annular support or ring a* is perforated or provided with holes or orifices a²
in order to allow a current of air to pass between the secondary reservoir a and-the
perforated plate or grating c and to circulate around the wick tube c' thus assisting

page_text: to keep cool those parts and consequently the oil in the secondary reservoir and at
the same time aiding the combustion of the flame.
In this example in lieu of the single central air tube described in the Specifications
of the hereinbefore recited Letters Patent I employ two air tubes e which may
conveniently be of arc shaped cross section passing through the secondary reservoir a
and I arrange them in such manner as to receive between them the lower end of
the depending wick tube or case c' and the wick c² by which means the wick and
surrounding parts will be kept cool and an efficient supply of air will be conducted
to the underside of the perforated plate or grating c adjacent to the flame.
The lower ends of the air tubes e are covered by a cap formed with a slot or
opening therein covered by a grating or air distributor f* capable of being
turned to bring the slot f' more or less across the air tubes e as indicated at Figure 6
and thereby increase or diminish and thus regulate the admission of air thereto.
In the examples given at Figures 7 and 8 I have shown a duplex burner and a
triplex burner respectively constructed according to my invention.
In these examples a single central air tube e is employed and the several wick
tubes c are arranged respectively at each side of the air tube e and around the
same in the form of a triangle.
In the example given at Figure 9 I have shown a triplex burner having the wick
tubes c arranged side by side and in this case two air tubes e are employed located
between the wick tubes c¹.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
:-
1. In a flat wick burner fed by gravity from a main reservoir the combination of
a secondary reservoir a perforated annular ring or support for the cone and a
perforated air distributing disc or grating loosely fitting into the annular support or
ring and carrying the wick tube or tubes substantially as herein shown and described
and for the purpose stated.
2. In a flat wick burner fed by gravity from a main reservoir the combination of
a secondary reservoir, a cone, a perforated ring or support for the cone a perforated
air distributing disc or grating loosely fitted into the annular support or ring and
carrying the wick tube or tubes, and an air tube or tubes passing through the
secondary reservoir substantially as herein shown and described and for the purpose
stated.
