Improvements in Oil Lamps.
I, GEORGE WRIGHT GWYER, Jnr., of 64 Cotham Road, Bristol, in the County
of Gloucester, Gentleman, do hereby declare the nature of this invention to be
as follows:
This invention is applicable to various kinds of lamps particularly to those for
magic lanterns, and in carrying it out I employ any suitable number of flat wicks
say for example two and divide the wick tube so that it has an air opening or space
between each wick. I also form suitable air conduits or channels at the outside'of
each wick so that each flame is between two currents of air. Where a single wick
was employed the two outside air supplies would be employed" no internal supply
being required, but where two or more wicks were employed the "inside as well as
the outside channels would be necessary.
.
The channels may be formed in any convenient manner the inside ones con-
veniently by the tube or space passing through the oil cistern and the outer ones by
means of plates or covers extending to near the wicks and supplying the air from
any suitable part of the lamp or casing.

COMPLETE SPECIFICATION.
Improvements in Oil Lamps.
I, GEORGE WRIGHT GWYER, Junior, of 64, 'Cotham Road, Bristol in the
County of Gloucester,' Gentleman; 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:-
ini
This invention relates to oil lamps having wicks other than round and especially
to flat wick lamps for magic lantern or similar display purposes though of course I
do not by any means limit myself to the purposes or uses to which lamps' made in
accordance with my present invention may be applied.
J...

And in order that my present invention may be easily understood and readily
carried into practice I will proceed to describe same with reference to the drawings
hereunto annexed-which drawings more particularly illustrate by way of example
a three wick (flat wicks) oil lamp specially designed for magic lanterns.

lowered by the wick raisers 6' c and d or controlled in' any other suitable manner
as is well understood.

tubes b and c.

9 is a plate or enclosing device mounted diagonally at one side and forming
between g and b the inclined air channel / leading in a diagonal direction (or there-
abouts) to the outside of wick in b.
i is similar plate to g forming similarly inclined outer air passage or channel j to
outer side of wick in d.
kis grating over the lower end of the outer air channel h, and
is similar grating over outer air channel j.
m is the burner hood diaphragm or dome having a single longitudinal slot or
opening n therein above the three wicks bed (see Figs. 2 and 3) so that the three
flames from these three burners burn through this said slot n or this dome and slot
may be arranged constructed and mounted in any other suitable way.
o is chimney hood or lower part of the chimney surrounding the burner and
advantageously formed of metal to resist the great heat imparted thereto from the
flames of the said burner.
This chimney hood o in the form of an arch is open at one end p and at the other
end has a reflector q so that an intensely powerful light is projected through the
said opening p.
Or any other suitably shaped lower part of the chimney or outer hood instead
of o may be used as desired.
s is the chimney.
The air passages e and f supply air to the inner side of wicks b and d respectively
and to both sides of c.
This latter wick tube c may also advantageously have a lip or flange c* formed or
mounted on the upper edge thereof each side-as this lip c* has been found to
greatly assist and benefit the light produced.
Air from the exterior of the lamp is also supplied (through the passages or
channels and respectively) to the outer sides of the wicks in b and d such air
currents being thus directed on to the outer side of each outer flame at an acute
angle thereto advantageously at an angle of about 45 degrees.
The effect of this self-induced outer air current through hand through j
projected onto each outer side respectively of the outer flames and under the hood
or dome m is to cause a very perfect combustion and consequently a very brilliant
light.
It will be obvious that instead of the particular form of outer channel shown in
the drawings-other equivalent or similar channel or channels on the outer side of
cach outer flame may be arranged or formed so as to lead a current of air to the
said flame at an acute angle thereto so as thus to project said current of air into the
flame in a corresponding manner to the currents of air coming through k―h and
lj respectively.
1 is a dummy shield or projection into the air passage e so as to reduce the size
of said passage e to correspond with the obstruction caused in passage f by reason
of the shield (see Fig. 3) around the wick raiser 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 oil lamps having air channels between two or more flat wicks-the com-
bination therewith of exterior air channels or air passages diagonally or otherwise
suitably inclined towards the outer side of each outer wick or flame therefrom
substantially in the manner and for the purposes hereinbefore described and
illustrated by way of example in the drawings hereunto annexed.
2. In oil lamps of the character described-with other than round wicks-the
arrangement and combination therewith of means to supply air on to the outsides
of the wick or outer side of the two outer wicks and direct such air onto same or
onto the flame or flames therefrom in a diagonal or other inclined direction substan-
tially in the manner and for the purposes hereinbefore set forth.

page_text: 3. In oil lamps of the character described-with other than round wicks--an oil
reservoir having three wicks and internal air passages such as e f between said
wicks in combination and acting in conjunction with plates such as g and i so
arranged and mounted as to form between them and the outer sides of the wick
tubes aud d respectively air passages or channels such as hand j leading the air
therefrom onto the respective flames from said wick tubes at an angle of about
45 degrees or thereabouts so as to act substantially in the manner and for the
purposes hereinbefore described and illustrated in the drawings hereunto annexed.
4. The improved arrangement and combination of parts constituting my improved
oil lamp having other than round wicks substantially in the manner and for the
purposes herein before described and illustrated in the drawings hereunto annexed.
