in the City of London, Patent Agent, for the Invention of "IMPROVE-
MENTS IN LAMPS FOR BURNING PETROLEUM AND OTHER SIMILAR OILS, AND IN
FEEDERS OR CANS FOR SUPPLYING SUCH OILS TO LAMPS."-A communication
from abroad by Noel Bosselut, of Paris, France.
Sealed the 21st August 1863, and dated the 25th-February 1863.
PROVISIONAL SPECIFICATION left by the said Richard Archibald Brooman
at the Office of the Commissioners of Patents, with his Petition, on the
25th February 1863.
I, RICHARD ARCHIBALD BROOMAN, of 166, Fleet Street, in the City of
London, Patent Agent, do hereby declare the nature of the said Invention for
"IMPROVEMENTS IN LAMPS FOR BURNING PETROLEUM AND OTHER SIMILAR OILS, AND
IN FEEDERS OR CANS FOR SUPPLYING SUCH OILS TO LAMPS," to be as follows:-
cap
I cover the glass or other reservoir with a cap having a circular hole in the
centre, to the sides of which aperture a ring with screw-threads is fixed. This
is dished round a portion of its surface, and apertures for the passage of
the liquid are made through the bottom of the dish. A crown is fixed on this
cap in such manner as to be capable of being turned; it is solid with the
exception of a slot or hole made in it; when the slot or hole is brought over,
the dished portion of the cap passage for the liquid to supply the reservoir is
opened; when the crown is turned so far round as to bring the aperture in
the crown over the solid part of the cap, communication with the interior is
shut off, and loss by evaporation through the supply aperture prevented. The
feeder or can is provided with a two-way cock opening into a nozzle, and com-
municating with the interior of the can when it is held in a position for pouring
out its contents; but when the can is in any other position the nozzle falls,.

page_text: and communication through the cock is thereby shut off. The gallery and
upper parts of the lamp are fixed in the ring before mentioned by a solid plug,
from which the gallery springs, being screwed into it. The plug is pierced
through the centre to receive a tubular wick holder; a lining is fixed inside
the wick holder, the edges of which are turned down at top over and upon the
tube, and thus the lining and tube are held together. The tube is fixed to the
under side of the plug by means of flanges carried out from the bottom of
the tube; slots are made in the wick holder and lining for the reception of
two spiked wheels fixed on an axis, on which a button is fixed, and extending
beyond the gallery for turning the wick up and down. The capsule or cap
through which the wick passes is formed in a piece with a tube and a ring, the
former for carrying the lamp chimney, and the other the globe, both resting
upon the upper part of the gallery; the sides of the gallery are open, and a
plate of wire gauze or perforated metal for dividing the air before passing
into the capsule is supported by a flange on the inside of the gallery.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Richard Archibald Brooman in the Great Seal Patent
Office on the 21st August 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, RICHARD
ARCHIBALD BROOMAN, of 166, Fleet Street, in the City of London, Patent
Agent, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her Letters
Patent, bearing date the Twenty-fifth day of February, in the year of our Lord
One thousand eight hundred and sixty-three, in the twenty-sixth year of Her
reign, did, for Herself, Her heirs and successors, give and grant unto me,
the said Richard Archibald Brooman, Her special licence that I, the said
Richard Archibald Brooman, my executors, administrators, and assigns,
or such others as I, the said Richard Archibald Brooman, 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, use, exercise, and vend, within
the United Kingdom of Great Britain and Ireland, the Channel Islands, and
Isle of Man, an Invention for "IMPROVEMENTS IN LAMPS FOR BURNING PETRO-
LEUM AND OTHER SIMILAR OILS, AND IN FEEDERS OR CANS FOR SUPPLYING SUCH
OILS TO LAMPS," (communicated to me from abroad by Noel Bosselut, of
Paris, France,) upon the condition (amongst others) that I, the said Richard
Archibald Brooman, my executors, or administrators, by an instrument

page_text: in writing under my, or their, or one of their hands and scals, 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 Richard Archibald Brooman, 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 in and
by the following statement thereof, reference being had to the Drawings
hereunto annexed, that is to say:-
I cover the glass or other reservoir with a cap having a circular hole in the
centre, to the sides of which aperture a ring with screw-threads is fixed. This
cap is dished round a portion of its surface, and apertures for the passage of
the liquid are made through the bottom of the dish. A crown is fixed on this
cap in such manner as to be capable of being turned; it is solid with the ex-
ception of a slot or hole made in it; when the slot or hole is brought over,
the dished portion of the cap passage for the liquid to supply the reservoir is
opened; when the crown is turned so far round as to bring the aperture in
the crown over the solid part of the cap, communication with the interior is
shut off, and loss by evaporation through the supply aperture prevented. The
feeder or can is provided with a two-way cock, opening into a nozzle and com-
municating with the interior of the can when it is held in a position for
pouring out its contents; but when the can is in any other position, the nozzle
falls, and communication through the cock is thereby shut off. The gallery
and upper parts of the lamp are fixed in the ring before mentioned by a solid
plug, from which the gallery springs, being screwed into it. The plug is
pierced through the centre to receive a tubular wick holder; a sheath is fixed
outside this wick holder, the edges of which are turned down at top over and
apon the sheath, and thus the sheath and tube are held together; the tube is
fixed to the under side of the plug by means of flanges carried out from the
bottom of the tube; slots are made in the wick holder and sheath for the.
eception of two spiked wheels fixed on an axis on which a button is fixed, and.
extending beyond the gallery for turning the wick up and down. The capsule
r cap through which the wick passes is formed in a piece with a tube and a
ing, the former for carrying the lamp chimney and the other the globe, both
esting upon the upper part of the gallery; the sides of the gallery are open,
nd a plate of wire gauze or perforated metal for dividing the air before
passing into the capsule is supported by a flange on the inside of the gallery.
Figure 1 of the accompanying Drawings is a vertical section of a lamp with

page_text: the present improvements applied thereto. A is a glass or other reservoir,
which is mounted on any suitable stand and covered with a cap B, having a
circular hole in the centre; E is a ring fixed to the cap. The cap is dished at
d, and apertures e are made through the the bottom of the dish; C is a crown
fixed on the cap B in such manner as to be capable of being turned; it is
solid, with the exception of a slot or hole g made in it. When this slot or hole
is brought over the disbed portion d of the cap passage to the liquid to supply
the reservoir, A is opened; when the crown C is turned so far round as to
bring the hole g over the solid part of the cap B, communication with the reser-
voir A is shut off, and loss by evaporation through the supply aperture
prevented. The extent to which the crown C can be turned is limited by a
screw or pin h passing through the crown. D is a feeder or can provided with
a two-way cock j opening into a nozzle i, and communicating with the interior
of the can when it is held in the position shewn in the Drawing, for pouring
out its contents; but when the can is in any other position, the nozzle i falls,
and communication through the cock j is thereby shut off. The ring E is
screw-threaded on its interior, and the gallery G is fixed thereto by a solid
plug m, from which the gallery springs, being screwed into it. The plug m is
pierced through the centre to receive a tubular wick holder H (see the detached
views, Figures 2 and 3), which is secured thereto by two flanges n, n, carried.
out from the bottom of the wick holder, as shewn at Figure 1. M is a sheath
outside the wick holder H, the edges of which are turned down at top over and
upon the sheath, and thus the sheath and wick holder are held together; slots
o, o, are made in the wick holder for the reception of two spiked wheels p, p,.
fixed on a spindle P, terminating in a button Q, for turning the wick up and
down. The sheath M is stamped or formed with vertical cheeks r, r, for sup-
porting the spindle P. The two spiked wheels p, p, united by a socket and
traversed by the spindle P, are placed between the cheeks r,. The sheath M.
is secured to the gallery by two projections 8, s, on the cheeks ", r, entering
corresponding holes in the plug m. The upper capsule or cap R is formed in
a piece with a tube S and a ring T, the former for carrying the chimney U,
and the latter the globe N. X is a plate of wire gauze or perforated metal for
dividing the air before passing into the capsule R; it is supported by a flange y
on the inside of the gallery G.
Figures 4, 5, and 6 are views of a modified form of the cap B and crown C.
When liquid is to be supplied to the reservoir of the lamp, the crown is turned
until its opening 9 is brought over the holes e in the cap B. The extent to
which the crown is free to turn is limited by a stop or pin h fixed to the crown
and free to travel in a slot f in the cap. To obtain a better effect from the

page_text: lamp, I form openings all round the crown, as represented in Figures 7 and
8; the air which enters by these openings and by the lower openings k is
divided by a plate of wire gauze or perforated metal r, which rests on projec-
tionss on the interior of the crown C. The crown G of the burner is boxed
in by the gallery H, see Figure 9; air enters the lamp through slots m, formed
in and round the gallery. The cylindrical part of the gallery H is surmounted
by openwork I and a neck n, which is pierced with holes for admitting air.
The cap R is formed in a piece with the gallery H. The lower flange of the
chimney is secured by two claws u and a screw v.
And having now described the nature of the said Invention, and in what
manner the same is to be performed, I declare that I claim as the " Improve-
ments in Lamps for Burning Petroleum and other similar Oils, and in Feeders
or Cans for supplying such Oils to Lamps,"
First, the employment in such lamps of a crown free to turn upon a cap
covering the oil reservoir, in such manner as to open a passage for the oil to
the reservoir when required, and to again close the passage when the oil has
been supplied, substantially as herein-before described and illustrated in the
accompanying Drawings.
Second, the arrangement of the wick holder and sheath, substantially as
herein-before described and illustrated in the accompanying Drawings.
Third, fitting to such lamps a gallery and a plate of wire gauze or perforated
metal, in manner and for the purposes herein-before described.
Fourth, constructing the capsule or cap with the chimney and globe holders
in one, substantially as herein-before described and illustrated in the accom-
panying Drawings.
And, fifth, constructing feeders or cans with a two-way cock, which is opened
for the passage of liquid when the can is held in position for pouring out its
contents, and which is closed when the can is in any other position, as herein-
before described and illustrated in the accompanying Drawings.
In witness whereof, I, the said Richard Archibald Brooman, have here-
unto set my hand and seal, this Fifteenth day of August, One thousand
eight hundred and sixty-three.
