Improvements in Lamps for Burning Illuminating Oils with a
Forced Air Supply.
We, JOHN HOWARD Ross, of 66, William Street, and RICHARD NOLAN, of
52, Great Brunswick Street, all in the City and County of Dublin, Ireland, Agents,
do hereby declare the nature of our invention for "IMPROVEMENTS IN LAMPS FOR
BURNING ILLUMINATING OILS WITH A FORCED AIR SUPPLY to be as follows:
""
This invention has for its object improvements in lamps for hurning illuminating
oils in combination with air supplied to a number of the same under pressure.
And our invention relates to a form of lamp adapted for use on brackets or
fittings such as those now used for gas.
We prefer to arrange the oil tanks feeding our improved lamps on the "gurgle
system on each floor (or on each floor fed by pipes from a main tank) such tanks
communicating by smaller pipes with the lamps so that the oil in the tanks and
burners or lamps is always at the same level, and thus one tank is able to supply
a number of lamps on the same floor of a building.
Wo connect the main fittings or pipes to which the brackets are attached to a
meter drum or other air compressor and an air holder adapted to maintain a
continuous pressure in the same.
Through or besides the brackets we place the small pipe for conveying the oil to
the lamp and connect the same to the main oil pipes leading to the tanks.
A chandalier can be formed by a combination of two or more brackets with a
central oil tank in connection with the forced air supply.
The improved lamp which forms the subject of the present invention consists of
an outer cylinder fitting in or on a chamber below the same furnished with a
drip plug for escape of superfluous oil at its bottom and a union at one side to
screw on the bracket.
In this lower chamber we arrange a diaphragm having a central orifice in the
same and covered with wire gauze.
This diaphragm carries lugs supporting an oil cylinder concentric with the other
cylinder and which oil cylinder carries the burner or burners. The usual slotted
cap fits over the top of the outer cylinder.
0
The small oil pipe enters the union in the lower chamber and projects through
the wire gauze covered orifice in the diaphragm into the oil cylinder thus keeping

page_text: the same supplied with oil at the level maintained in the supply tanks, or instead
of the lower diaphragm already described we fix near the top of the outer cylinder
and below the burners an annular gauze diaphragm between the outer and inner
cylinders so that the volume of air rushing under pressure through the bracket
pipe or stem and circulating between the outer and oil cylinders is broken up and
more uniformly diffused on the flame or flames.
Any excess of oil escaping over the wick or wick tube drips into the concentric
space between the cylinders and so into the lower chamber and can be removed by
unscrewing the drip plug.
The usual tap on the bracket can adjust the forced air current.
By this construction of lamp no large oil reservoir to throw a shadow is used
below the burner or wick as in most lamps burning on the forced air principle.
This arrangement of bracket lamp with forced air supply is advantageous for
ships, railway carriages, etc., as well as for buildings.
For railway carriages we might utilise the axles of the carriages to drive the
drum supplying the air holder.

page_text: Our invention relates to a means of burning illuminating oils with a forced air
supply and has for its object improvements in lamps for such purpose and for
supplying oil to the same.
We arrange the oil tanks feeding our improved lamps on the "gurgle system"
on each floor or on each floor fed by pipes from a main tank, such pipes communi-
cating by smaller pipes with the lamps so that the oil in the tanks and burners or
lamps is always at the same level and thus one tank is able to supply a number
of lamps on the same floor of a building or a number of burners on one chandelier.
We connect the main fittings or pipes to which the brackets carrying the lamps
are attached to a meter, drum or other air compressor and an air holder adapted to
maintain a continuous and uniform pressure in the same.
Through or beside the bracket A carrying the lamp we place the small pipe B
for supplying oil. This pipe B connects at C by a horizontal or other opening
with the regulating tank or vessel D placed on the bracket, chandelier, or other-
wise at the level of the burners and which is connected by port E to the pipes
from the main tank placed in any suitable part of the room or building.
Over port E is a valve seating F through which works a valve spindle G carrying
a valve H formed to fit the scating.
The spindle G also carries a buoyant body or float I and the other end of the
spindle is guided in a socket in the tank or vessel D. J is an air escape pipe.
As the oil is consumed, the float I sinks thereby opening the valve H and
admitting more oil. When the tank is full enough, the float rising, shuts off the
oil supply from E by the valve H closing on its seating.
For street lamps and the like the wick-tube of the lamp may be made large
enough to contain the regulating tank as described.
A chandelier can be formed by the combination of two or more brackets with a
central oil regulating tank connected by means of a small pipe passing up through
or beside the central air pipe to the main oil tank or cistern and with a forced air
supply.
K. is an outer cylinder of our lamp fitting in or on a chamber L below the same
furnished with a drip plug M for escape of superfluous oil, at its botton and a
union N at one side to scrow to the bracket. For standard lights the connection
may be at the bottom of chamber L and the drip plug attached to the bottom of
the standard.
Cylinder P is connected with the oil pipe B the oil cylinder P being concentric
with the outer cylinder K and which oil cylinder P carries the burner or
burners Q.
The usual slotted cap R fits over the top of the outer cylinder K.
The small oil pipe B enters the union N in the lower chamber L and projects
into the oil cylinder P thus keeping the same supplied with oil at the level
maintained in the supply tank E. We fix at the top of the outer cylinder K. or if
desired at the bottom of the oil cylinder P an annular gauze diaphragm S between
the outer K and inner P cylinders so that the volume of air rushing under pressure
through the bracket pipe or stem and circulating between the outer K and oil P
cylinders is broken up and more uniformly diffused in the flame or flames.
Of course instead of cylinders these tubes K and P could be square or of other
form.
Any excess of oil escaping over the wick or wick-tube drips into the concentric
space between the cylinders K. P. and so into the lower chamber L and can be
removed by unscrewing the drip plug M. The usual tap on the bracket can adjust
the forced air supply.
By this construction of lamp no large oil reservoir to throw a shadow is used
below the burner or wick as in most lamps and if desired to throw the light more
downwards the burner carrying the wick and the slotted cap R may be made to
project horizontally from the top of the oil cylinder P and outer cylinder K
respectively.

page_text: This arrangement of lamp for attaching to gas fittings with forced air supply is
advantageously applicable to ships, railway carriages &c as well as to buildings.
For railway carriages we might utilize the axles of the carriages when in motion
to drive the drum or other air compressor supplying the air holder as referred to
in 1109094.
Having now particularly described and ascertained the nature of our invention
and in what manner the same is to be performed we declare that what we
claim is
Firstly. The construction and general arrangement of oil burner substantially as
described with reference to the accompanying drawings, in combination with a
regulated oil supply from a tank or tanks as described, fed by a main tank or
cistern and with an air compressor or forcer and holder for supplying a continuous
or regulated blast to the lamps substantially as and for the purposes described.
Secondly. Applying regulating tanks (or fitting oil regulators in ench-lum)
substantially as hereinbefore-described, and fed by a main cistern or tunk, to supply
oil burners as described supplied-with-a-forced continuous-or-regulated blust of air;
the said tanks or regulators being placed at the level of the burners se us to unto-
matically control the supply of oil to such forced air oil burners and admit of the
same being regularly-fed-with oil when placed at the same or varying levels with
each other as compared with the level of the main tank or cistern substantially-us
described.
Thirdly. The general arrangement of lighting system having a constant-auto-
matie oil supply and continuous forced air cupply to a number of wil burners
substantially as described and illustrated in the accompanying drawings.

Improvements in Lamps for Burning Illuminating Oils with a
Forced Air Supply.
We JOHN HOWARD Ross of 33 Wicklow Street and RICHARD NOLAN of
52 Great Brunswick Street all in the city and county of Dublin, Ireland, Agents,
do hereby declare the nature of this invention for IMPROVEMENTS IN LAMPS FOR
BURNING ILLUMINATING OILS WITH A FORCED AIR SUPPLY and in what manner
the same is to be performed to be particularly. described and ascertained in and by
the following statement:-
Referring to the accompanying drawings
Fig. 1. is a vertical section of a lamp constructed according to our invention
with our improved oil supply cistern system and with air supply in accordance
with Letters Patent granted to the said John Howard Ross and one John MoVey
11090 of 1884 and
Fig. 2. is a vertical section of the regulating oil tank or cistern the two being
shewn mounted on a bracket.

page_text: Our invention relates to a means of burning illuminating oils with a forced air
supply and has for its object improvements in lamps for such purpose and for
supplying oil to the same.
"
We arrange the oil tanks feeding our improved lamps on the "gurgle system'
on each floor or on each floor fed by pipes from a main tank, such pipes communi-
cating by smaller pipes with the lamps so that the oil in the tanks and burners or
lamps is always at the same level and thus one tank is able to supply a number
of lamps on the same floor of a building or a number of burners on one chandelier.
We connect the main fittings or pipes to which the brackets carrying the lamps
are attached to a meter, drum or other air compressor and an air holder adapted to
maintain a continuous and uniform pressure in the same.
Through or beside the bracket A carrying the lamp we place the small pipe B
for supplying oil This pipe B connects at C by a horizontal or other opening
with the regulating tank or vessel D placed on the bracket, chandelier, or other-
wise at the level of the burners and which is connected by port E to the pipes
from the main tank placed in any suitable part of the room or building.
Over port E is a valve seating F through which works a valve spindle & carrying
a valve H formed to fit the seating.
The spindle G also carries a buoyant body or float I and the other end of the
spindle is guided in a socket in the tank or vessel D. J is an air escape pipe.
As the oil is consumed, the float I sinks, thereby opening the valve H and
admitting more oil. When the tank is full enough, the float I rising, shuts off the
oil supply from E by the valve H closing on its seating.
For street lamps and the like the wick-tube of the lamp may be made large
enough to contain the regulating tank as described.
A chandelier can be formed by the combination of two or more brackets with a
central oil regulating tank connected by means of a small pipe passing up through
or beside the central air pipe to the main oil tank or cistern and with a forced air
supply.
K. is an outer cylinder of our lamp fitting in or on a chamber L below the same
furnished with a drip plug M for escape of superfluous oil, at its bottom and a
union N at one side to screw to the bracket. For standard lights the connection
may be at the bottom of chamber L and the drip plug attached to the bottom of
the standard.
Cylinder P is connected with the oil pipe B the oil cylinder P being concentric
with the outer cylinder K and which oil cylinder P carries the burner or
burners Q.
The usual slotted cap R fits over the top of the outer cylinder K.
The small oil pipe B enters the union N in the lower chamber L and projects
into the oil cylinder P thus keeping the same supplied with oil at the level
maintained in the supply tank E. We fix at the top of the outer cylinder K. or if
desired at the bottom of the oil cylinder Pan annular guaze diaphragm S between
the outer K and inner P cylinders so that the volume of air rushing under pressure c
through the bracket pipe or stem and circulating between the outer K and oil P
cylinders is broken up and more uniformly diffused in the flame or flames.
Of course instead of cylinders these tubes K and P could be square or of other
form.
Any excess of oil escaping over the wick or wick-tube drips into the concentric
space between the cylinders K. P. and so into the lower chamber L and can be
removed by unscrewing the drip plug M. The usual tap on the bracket can adjust
the forced air supply..
By this construction of lamp no large oil reservoir to throw a shadow is used
below the burner or wick as in most lamps and if desired to throw the light more
downwards the burner carrying the wick and the slotted cap R may be made to
project horizontally from the top of the oil cylinder P and outer cylinder K
respectively.

page_text: This arrangement of lamp for attaching to gas fittings with forced air supply is
advantageously applicable to ships, railway carriages &c as well as to buildings.
For railway carriages we might utilize the axles of the carriages when in motion
to drive the drum or other air compressor supplying the air holder as referred to
in 110908.
Having now particularly described and ascertained the nature of our invention
and in what manner the same is to be performed we declare that what we
claim is
Firstly. The construction and general arrangement of oil burner substantially as
described with reference to the accompanying drawings, in combination with a
regulated oil supply from a tank or tanks as described, fed by a main tank or
cistern and with an air compressor or forcer and holder for supplying a continuous
or regulated blast to the lamps substantially as and for the purposes described.
Secondly. Applying regulating tanks (or fitting oil regulators in each lamp)
substantially as hereinbefore described, and fed by a main cistern or tank, to supply
oil burners as described supplied with a forced continuous or regulated blast of air,
the said tanks or regulators being placed at the level of the burners so as to auto-
matically control the supply of oil to such forced-air oil burners and admit of the
same being regularly fed with oil when placed at the same or varying levels with
each other as compared with the level of the main tank or cistern substantially as
described.
Thirdly. The general arrangement of lighting system having a constant auto-
matic oil supply and continuous forced air supply to a number of oil burners
substantially as described and illustrated in the accompanying drawings.
