-
The said Invention consists of the improvements hercin-after described
in constructing and arranging the parts of lanterns and other kinds of

page_text: lamps for burning kerosino and other volatile liquid hydrocarbons, the
object of the said Invention being principally to obtain a brilliant and
steady flame, and to prevent the smoking of the globe or glass of the
lantern or lamp.
I will describo the said Invention in connection with a lantern, to
which it is particularly applicable -
Immediately over the globe or glass of the lantern and at a short
distance above it is a flat cylindrical air chamber having a central
opening in its under concave side. This air chamber is connected by
means of tubes opening into it at opposite sides with the collar, imme-
diately under the burner, which collar is perforated with small holes.
The air for supporting the combustion of the flame delivered under
the cone of the burner is supplied in part from tho said air chamber,
passing down the said tubes and in part from the external atmosphere
through the perforated collar. A perforated disc or gallery carried by
the burner supports the glass or globe, and through the said perforated
gallery. air is supplied to the flame above the cone of the burner. The
upper end of the glass or globe is surrounded and supported by a spring
wire clip carried by the cylindrical air chamber described.
By the arrangement of air chamber described the height of the lantern
is considerably reduced, and its height is still further reduced. by dis-
pensing with the ordinary oil cup or reservoir and converting the hollow
bottom or foot of the lamp into an oil cup or reservoir.
The glass or globe may be guarded by a wire guard made to slido.on
the air tubes described, and a ring is fixed on the top of the cylindrical
air chamber to carry the lantern by.
The several improvements herein-before described in connection with
a lantern may be applied wholly or in part to other kinds of lamps for
burning kerosine or other volatile liquid. hydrocarbons.

Letters Patent, bearing date the Twenty-fourth day of December, in the
year of our Lord One thousand eight hundred and seventy-three, in the
thirty-seventh year of Her reign, did, for Herself, Her heirs and
successors, give and grant unto me, the said John. Wickliffe Egginton,
Her special license that I, the said John Wickliffe Egginton, my exe-
cutors, administrators, and assigns, or such, others as I, the said John
Wickliffe Egginton, my executors, administrators, and assigns, should
at any time agree with, and no others, from time to time and at
all times thereafter during the term therein expressed, should and
lawfully might make, usc, exercise, and vend, within the United
Kingdom of Great Britain and Ireland, the Channel Islands, and 'Isle of
Man, an Invention for "IMPROVEMENTS IN LANTERNS AND OTHER KINDS OF
LAMPS FOR BURNING KEROSINE AND OTHER VOLATILE LIQUID HYDROCARBONS," a
communication to me from abroad' by John Henry Stone, of Hamilton,
in the Province of Ontario, Canada, upon the condition (amongst others)
that I, the said John Wickliffe Egginton, my executors or administrators,
by an instrument in writing under my, or their, or one of their hands
and seals, should particularly describe and ascertain the nature of the
said Invention, and in what manner the same was to be performed, and
cause the same to be filed in the Great Seal Patent Office within six
calendar months next and immediately after the date of the said, Letters
Patent.
NOW KNOW YE, that I, the said John Wickliffo Egginton, do hereby
declare the nature of the said Invention, and in what manner the
same is to be performed, to be particularly described and ascertained
and by the following statement thereof, that is to say :-
. The said Invention consists of the improvements herein-after described
in constructing and arranging the parts of lanterns and other kinds of
lamps for burning kerosinc and other volatile liquid hydrocarbons, the
object of the said Invention being "principally to obtain a brilliant and
steady flame and to prevent the smoking of the globe or glass of the
lantern or lamp, and also to reduce the height of the ordinary lantern
or lamp.
I will describe the said Invention in connection with a lantern, to

page_text: Immediately over the globe or glass of the lantern and at a short
distance above it is a flat cylindrical air chamber having a central
opening in its inner concave side. This air chamber is connected. by
means of tubes opening into it at opposite sides with the collar imme-
diately under the burner, which collar is perforated with small holes.
The air for supporting the combustion of the flame delivered under
the cone of the burner is supplied in part from the said air chamber
passing down the said tubes and in part from the external atmosphere
through the perforated collar. A perforated disc or gallery carried by
the burner supports the glass or globe, and through the said perforated 1
gallery air is supplied to the flamo above the cone of the burner. The
upper end of the glass or globe is surrounded and supported by a spring
wire clip carried by the cylindrical air chamber described.
]
...The glass or globe may be guarded by a wire guard made to slide on
the air tubes described, and a ring is fixed on the top of the cylindrical 1
air chamber to carry or suspend the lantern by.
I will now describe with reforenco to the accompanying Drawing the
manner in which the said Invention may be carried into effect.
Figure 1 represents in side clevation and Figure 2. in vertical section a
lantern for burning kerosine or other volatile liquid hydrocarbon, con- 2
structed according to the said Invention.
Figure 3 is a plan of the under side of the air chamber of the lantern;
and Figure 4 represents a side clevation and plan of the spring wiro clip
applied to the glass or globe used for supporting the upper part of the
said glass or globe. The same letters indicate the same parts in the 2
several Figures of the Drawing.

a is the hollow foot or bottom of the lantern or lamp constituting the
oil cup or reservoir. The said oil cup or reservoir carries a casing or
collar b, within which the burner c of the lamp is situated (seo Figure 2).
The collar or casing 6 is covered and prolonged upwards by the lower
part 6 of the cone 6 of the burner, the said lower part 6 of the cone
fitting upon and around the burner in the manner represented. The
said collar or casing 6 is perforated at 6' with small holes (see Figure 1).
On the said collar or casing 6, 63, is a perforated gallery e, on which the
bottom of the globe or glass fis supported. Immediately over the said
globe or glass f and at a short distanco above it is a flat cylindrical air

chamber (shown separately in plan of under side in Figure 3) having
a central opening in its under concavo side.
On opposite sides of the lantern or lamp are vertical air tubes h, h,
the
upper ends of which open into the air chamberg and the lower ends
or horizontal branches h³, h³, open into the perforated collar or casing b.
The air which is delivered under the cone of the burner c is in part
supplied from the air chamber g, the said air from the chamber being
conveyed by the tubes h, h, h³, h³, to the collar or casing 6, 6%, in which
the burner is situated. Air is also delivered under the cone of the
burner by passing from the external atmosphere through the perforated
collar or casing b, b³. The course of the air from the air chamber g
through the air tubes h, h³, into the casing or collar b, 6ª, is indicated by
the arrows in Figure 2. Air is supplied above the cone of the burner
through the perforated gallery e. By placing the burner c of the lantern
or lamp in the collar or casing and supplying air to the said collar or
casing in the manner described a steady and brilliant flame is obtained,
and the smoking of the glass or globe is prevented. ¿ is the spring wire
clip for supporting the upper part of the glass or globe. The said clip
is fixed by its ends to the under side of the cylindrical air chamber g.
The said clip, as will be seen by reference to Figure 4, embraces the part
f of the glass or globe f, and when it is required to remove the said
glass or globe from the gallery it is only necessary to lift the handle end
when the clip is removed from the glass or globe and the latter
released. The glass or globe f is guarded by the wire guard & secured
on the air tubes / by a sliding motion. The lantern may be carried or
suspended by means of the ring 7 on the summit of the air chamber g.
By the arrangement of the air chamber described the height of the
lantern is considerably reduced, and its height is still further reduced by
dispensing with the ordinary oil cup or reservoir, and converting the
hollow bottom or foot of the lamp into an oil cup or reservoir, as repre-
sented.
The several improvements herein-before described and illustrated in
connection with a lantern may be applied wholly or in part to other
kinds of lamps for burning kerosine or other like volatile liquid bydro-
carbons.
Having now described the nature of the said Invention and in what

page_text: do not limit myself to the precise details herein described and illustrated,
as the same may be varied without departing from the nature of the said
Invention, but I claim as the said Invention of improvements in lanterns
and other kinds of lamps for burning kerosine and other volatilo liquid
hydrocarbons,―
First. The construction and combination of the air chamber.g,.g², and
air tubes h, h, h³, ², for conveying air to the under side of the conc. of
the burner, substantially as herein-before described and illustrated in the
accompanying Drawing.
i
Secondly, Placing the burner of the lantern or lamp in a perforated 1
collar or casing 6, 6, and conveying air to the said collar,or casing, sub-
stantially as and for the purpose herein-before described and illustrated
in the accompanying Drawing.
Thirdly. The combination of the oil cup and hollow bottom a of tho
lantern or lamp with the parts b, b, g, h, h³, substantially as and for tho 1
purpose herein-boforo described and illustrated in the accompanying
Drawing.
In witness whereof, I, the said John Wickliffe Eggington, havo
hereunto set my hand and scal, this Ninth day of May, in tho
year of our Lord One thousand eight hundred and seventy-four. 2
