We, WALTER PETER CHERRY and GEORGE ERNEST CHERRY, both of Porter
Street, in the Borough of Kingston upon Hull in the County of the same Town
Manufacturers do hereby declare the nature of said invention for IMPROVEMENTS
IN RAILWAY CARRIAGE AND OTHER LAMPS FOR ILLUMINATING PURPOSES, to be as
follows:-
Our invention relates to improvements in the construction of that class of lamps
known as roof lamps for illuminating railway carriages, which improvements can
also be applied to other lamps of similar form.
In order to carry out the said improvements we dispense with the ordinary
portable oil chamber and burner that is now generally used for burning colza oil,
and use in its place a portable petroleum lamp for burning petroleum or other
mineral oil so arranged as to fit the present form of lamp case used in railway
carriages to hold the present form of lamp.
The improved lamp is constructed with a metal shade or reflector having a
chimney attached thereto, the shade or reflector being made so as to fit closely into
the present form of lamp case and so as to rest on a projecting rim formed or to be
formed on the inside of the said lamp case, also to prevent air being supplied to the
burner to support combustion except through tubes provided for the purpose and
hereinafter described.
The burner we employ for burning the petroleum or other mineral oil is made of
ordinary construction and such as is commonly used for petroleum or mineral oil
lamps, excepting that the outer air passages to the said burner are stopped up, and
two bent or straight tubes are fitted to the said burner instead, and carried
upwards and through the metal shade or reflector and securely fitted thereto, 80 as
to supply air to the burner to support combustion of the flame. The oil chamber
for supplying oil to the burner is made of glass or metal and is so arranged as to
Bcrew on to the bottom part of the said burner. Air tubes are fitted, or
perforations made in the upper part of the lamp case to supply air to the interior
of the case for the support of the lamp flame, and the outlet of the lamp case is
made larger so as to allow the products of combustion to pass away more freely.
The chimney attached to the metal shade or reflector herein before described is
employed to increase the brilliancy of the lamp flame and to draw off the
products of combustion when the lamp is burning in the interior of the lamp case.
The chief advantages obtained by our improvements are an improved light and
at a less cost than the light now used.

WALTER PETER CHERRY and GEORGE ERNEST CHERRY of 90 Porter Street in the
Town and Borough of Kingston upon Hull in the county of the same Town, Lamp
Manufacturers, do hereby declare the nature of our invention for IMPROVEMENTS
IN RAILWAY CARRIAGE AND OTHER LAMPS FOR ILLUMINATING PURPOSES, and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :—
Our Invention relates to improvements in the construction of that class of lamps
known as roof lamps for illuminating railway carriages, which said improvements
can also be applied to other lamps of similar form. The chief advantages, obtained
by our improvements are an improved light and at a less cost than the light now
used. In order to carry out the said improvements we dispense with the ordinary
portable oil chamber and burner, that is now generally used for burning colza oil,
and construct in its place a portable petroleum lamp for burning petroleum or
other mineral oil which said improved lamp is so arranged as to fit the present
form of lamp case, used in railway carriages to hold the present form of lamp.
The said improved portable lamp consists of forming a metal shado or reflector
with a chimney attached thereto. The said shade or reflector being made so as to
fit closely into the present form of lamp case, and so as to rest on a projecting rim
formed on the inside of the said lamp case, also to prevent air being supplied to
the burner to support combustion except through tubes provided for the purpose
and hereinafter described. The burner we employ for burning the petroleum or
other mineral oil is of ordinary construction and such as are commonly used for
petroleum or mineral oil lamps, only the outer air passages to the said burner
are stopped up and two bent or straight tubes are fitted to the said burner instead,
and are carried upwards and through the metal shade or reflector and securely
fitted thereto, so as to supply air to the burner to support combustion of the flame.
The oil chamber to supply oil to the burner is made of glass or metal and is so
arranged as to screw on to the bottom part of the said burner. Air tubes are fitted
or perforations are made in the upper part of the lamp case so as to supply air to
the interior of the case for the support of the lamp flame, and the outlet of the
said lamp case is made larger so as to allow the products of combustion to pass
away more freely. The chimney attached to the metal shade or reflector herein-
before described is employed to increase the brilliancy of the flame and to draw off
the products of combustion when the lamp is burning in the interior of the lamp
case.
Figure 1 of the Drawings we illustrate a portable lamp according to our
invention as bereinbefore described. A. is the burner which is of ordinary
construction, and such as are commonly used for petroleum or other mineral oil
lamps, we find a great advantage is obtained by the use of this burner on account
of it having a perforated grate fitted below the dome of the same, so as to distribute
the air uniformly to the fame and also to prevent the heat from striking down the
wick tube. The gallery of the said burner being dispensed with and the outer air

page_text: passages to the same for supplying air for combustion of the flame are stopped up
by means of a metal plate. B. B are two bent metal tubes which are fitted to the
said burner and are carried upwards and through the metal shade or reflector C,
and are securely fitted thereto so as to supply air to the burner for combustion of
the flame when the lamp is burning in the said lamp case. D. is the metal chimney
attached to the said reflector C which is used to increase the brilliancy of the flame
and to draw off the products of combustion when the lamp is burning in the
interior of the lamp case. E is the oil chamber which is made of metal or glass
and is arranged with a screw collar so as to screw on the boddy of the burner A
for supplying oil to the same.
Figure 2 of the drawings is a sectional view of the portable lamp as shewn and
descred at Figure 1.
Figure 3 of the drawings we illustrate the lamp case for holding the said
portable lamp. F. F. are two rows of perforations made in the upper part of the
lamp case so as to supply air to the interior of the case for the support of the lamp
flame. G is a wind guard which is fitted in the upper part of the lamp case so as
to prevent wind from entering the case to extinguish the lamp flame. H is the
outlet of the lamp case which is made larger so as to allow the products of
combustion to pass away more freely. Figure 4 of the drawings we illustrate the
portable lamp fitted in the interior of the lamp case which forms a railway carriage
roof lamp for illuminating purposes.
Having now particularly described and ascertained the nature of our said
Invention, and in what manner the same is to be performed, we declare that what
we claim is
First. The combination and arrangement of parts A. B B. C. D and E as shewn
and described at Figure 1 and 2 of the accompanying drawings.
Second. The combination and arrangement of parts G. and perforations F F as
shewn and described at Figure 3 of the acompanying drawings.
Third. The combination and arrangement of parts A. B B. C. D. E. F F. G and H
so as to form a railway carriage roof lamp for illuminating purposes substantially
as shewn and described at Figure 4 of the accompanying drawings.
Fourth. The application of the aforesaid improvements to other lamps of similar
form.
