PROVISIONAL SPECIFICATION left by the said James Charles Morrison
and Robert Smith at the Office of the Commissioners of Patents on the
22nd December 1883.

This Invention relates to improvements in the construction of burners having
two or more circular wick cases as described in the Specification of Letters Patent
dated the 12th day of May 1879. N° 1873 and granted to Friederich Wilhelm
Wessel, the object of such improvements being principally to regulate and
distribute the supply of air to the interior of the outer flame and to the inner
flames.
We employ a peculiar arrangement of division plates between the wick cases
of burners consisting of two or more circular wick cases arranged concentrically
and constructed as described in the Specification herein before referred to. One
division plate is arranged in a more or less upright position within the air space
between the back portions of the wick cases and two plates are arranged, one on
each side, at an angle inclining towards the conical openings between the side
edges of the wick cases. The division plates commence a short distance from the
bottoms of the wick cases and terminate before reaching the upper ends thereof,
and they are so constructed as to extend, at their lower ends, across the air space,
in which they are arranged, between the two wick cases and to decrease in width
towards their upper ends at which point they are attached to the outer case of
the inner burner, or to the inner case of the outer burner, as may be desired. In
some cases, we arrange, in front of each of the said inclined plates, a division
plate, in a more or less upright position. The upper ends of the inclined plates,
which are in close proximity to the corresponding ends of the last mentioned
plates, are made to extend slightly beyond the latter.

page_text: Circular burners constructed of two or more flat wick cases as herein before
referred to usually have the mechanism for regulating the height of the wick
contained by the exterior wick holder or case covered by a case which extends
over a portion of the conical opening at the lower part of the burner, in such
burners it will be found that the partial closing of the said conical opening by
preventing a sufficient supply of air from entering the space or spaces between the
wick holders, is the cause of diminishing the intensity of the light obtained and
in order to obviate this difficulty it will be found advantageous to form a number
of perforations in the said case, or, when desired, the said case may be constructed
to terminate at each side of the conical opening.
It is desirable, in all cases, that the conical openings between the side edges of
the wick cases should be in juxta-position with each other.

IN
Our said invention relates to improvements in the construction of burners
having two or more wick cases or holders of a circular shape for containing flat
wicks and provided with a conical opening in the side for the admission of air
substantially as described in the specification and drawings annexed thereto of
Letters Patent dated the 12th day of May 1879 N° 1873 and granted to Friederich
Wilhelm Wessel, the object of these improvements being principally to regulate
and distribute the supply of air to the interior of the outer flame and to the
inner flames.
Each wick case or holder of the nature hereinbefore described has a conical
opening in the side for the admission of air and for the purposes of this invention
we employ a peculiar arrangement of division plates between the wick cases or
holders of burners consisting of two or more wick cases or holders of a circular
shape arranged concentrically and constructed in the manner hereinbefore referred
to. Two or more plates are arranged, that is to say, one at least, on each side at
an angle inclining towards the conical openings between the side edges of the
wick cases.
The division plates commence a short distance from the bottoms of
the wick cases and terminate before reaching the upper ends thereof and they are
so constructed as to extend, at their lower ends, across the air space in which they
are arranged between the two wick cases and to decrease in width towards their
upper ends at which point they are attached to the outer case of the inner burner
or to the inner case of the outer burner as may be desired. In some cases, we
arrange in front of each of the said inclined plates, a division plate, in a more or
less upright position. The upper ends of the inclined plates, which are in close
proximity to the corresponding ends of the last mentioned plates, are made to
extend slightly beyond the latter.
Circular burners constructed of two or more flat wick cases as herein before
referred to usually have the mechanism for regulating the height of the wick
covered by a case which extends over a portion of the conical opening at the
lower part of the burner. In the larger or compound burners it will be found that
the partial closing of the said conical opening by preventing a sufficient supply of
air from entering the space or spaces between the wick holders is the cause of
diminishing the intensity of the light obtained, and in order to obviate this
difficulty it will be found advantageous to form a number of perforations in the
said case, or, when desired, the said case may be constructed to terminate at each
side of the conical opening.
It is desirable, in all cases, that the conical openings between the side edges
of the wick cases should be in juxta-position with each other. The lower part or
parts of each air space between the wick cases or holders and also the bottom
of the air space in the centre case or holder are closed or partially closed.
We will now proceed to refer to the accompanying drawings from which the
nature of our said invention will be more clearly understood. The same letters of
reference indicate like parts in all the Figures. Figure 1. is a view of a wick case
or holder of a circular shape for containing a flat wick and arranged with a conical
opening between the side edges. Figure 2. is a cross section of a burner composed
of two similar wick cases of a circular shape. Figure 3. is a transverse section of
the same through the line x. y. Figure 4. is a side view of the inner wick case

page_text: showing the position of one of the inclined division plates, and Figure 5. is a
similar view of the inner wick case with a division plate in a more or less upright
position, arranged in front of the inclined division plates. A. A¹. are the circular
wick cases and a the conical openings between the side edges thereof. C. C. are
inclined division plates of which two or more may be used, and D. D. are division
plates, which are, in some cases, arranged in front of the plates C. C. E. is a small
plate which is, in some cases, arranged a short distance in front of the lower part
of the conical opening in the outside wick case or holder to modify the entrance of
air to the air spaces.
Having thus described and ascertained the nature of our said invention and the
manner in which the same is to be performed we would observe in conclusion
that what we consider novel and original and therefore claim as constituting
the invention secured to us by the said hereinbefore in part recited Letters
Patent, is :-
First. The employment of inclined division plates such as C. C. within the air
spaces of oil burners constructed of two or more wick cases of a circular shape as
bereinbefore referred to, substantially as hereinbefore set forth and described.
Secondly. In burners constructed of two or more wick cases of a circular shape
as herein before referred to, the arrangement of inclined division plates such as
C. C. together with division plates such as D. D. fixed in a more or less upright
position, substantially as hereinbefore set forth and described.
And thirdly. The combination of parts forming our improved burner constructed
substantially as herein described and illustrated in the drawings annexed.
In witness whereof we the said James Charles Morrison and Robert Smith have
hereunto set our hands and seals this eighteenth day of June in the year of our
Lord One thousand eight hundred and eighty four.
