WILLIAM BUTLER, 14, Thurlow Hill, West Norwood, London, S.E., Engineer,
do hereby declare the nature of this invention to be as follows:-
The paraffin oil is placed in a storage tank on the ground level a pump is fixed
and connected to the storage tank by pipes which will pump the paraffin oil from
the storage tank through pipes up to a receiving tank at the top of a building
placed outside in a convenient position or the tank may be placed inside the
building.
Pipes may be connected to the receiving tank and fitted and connected to as
many chandeliers and brackets, as are required in the building, to convey the
paraffin oil to the burners on the chandeliers and brackets. The same system may
be applied to street lighting and railway station lighting and all kinds of lamps.
The regulating feed may be constructed as follows; an outside metal container
with lid to contain an air tight float the supply pipe entering the top of the outside
container descending through the center of the air tight float. At the bottom
of the float a screw cap is fixed, containing a seating of india rubber, leather,
or cork..
The buoyancy of the float raises the seating of india rubber, leather, or cork in
the screw cap, which is connected to the bottom of the float; against the end of
inlet chamber of the supply pipe and effectually stops the flow of paraffin oil into
the outer metal container.
The paraffin oil is used from the outer metal container, the float falls and
allows the paraffin oil to flow into the outer metal container for use in regulated
quantities as required for burning.
The inlet chamber of the supply pipe is pierced with different sized holes to
suit different pressures and quantities of paraffin oil required for use.
Or the regulating feed may be constructed as follows, an outside metal container
with lid to contain an air tight float, the supply pipe entering the bottom of the
outside metal container, 2 metal levers are connected to the bottom of the float and
the 2 metal levers are connected to a plunger working in a suitable guide, the
metal plunger is faced with india rubber, leather or cork, the buoyancy of the
float acts on the 2 metal levers and compresses the face of the plunger on the face
of the inlet chamber of supply pipe at the bottom of the outside metal container,
and effectually stops the flow of paraffin oil. The paraffin oil is used from the
outside metal container, the floats falls, the 2 metal levers connected to the float
raise the plunger and allow the paraffin oil to flow into the outside metal container
for use in regulated quantities as required.
The inlet chamber is pierced with different sized holes to suit different pressures
and quantities of paraffin oil required for use.
An improved chandelier for burning paraffin oil, at one or as many branches
or arms as may be required on the chandelier.
The chandelier may be constructed as follows, the chandelier may be made to
slide up and down a central tube by the aid of balance weights and chains, and

page_text: revolve in a cup and ball joint at the level of the ceiling, or may be made to
revolve in cup and ball joint only. To effectually confine the oil to the chandelier
a liquid metal packing is used, in the central down tubes of the chandelier, the
liquid metal packing may be mercury or quicksilver, which effectually confines
the paraffin oil to the chandelier when moved up or down or turning round while
burning and when not burning.
Either of the above described regulating feeds may be fitted to the chandelier
to regulate the paraffin oil to the burners for burning.
An improved stop valve for paraffin oil to be constructed as follows:-An
outer metal container with an outlet chamber at the bottom of container a metal
plunger faced with india rubber, leather, or cork is fitted in a suitable guide and
descends on the face of the outlet chamber by balance weight or spring which
effectually stops the paraffin oil from flowing through and when the plunger is
raised the paraffin oil will flow through.

I, WILLIAM BUTLER, 14, Thurlow Hill, West Norwood, London, S.E., Engineer,
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; ---
My invention relates to an improved paraffin oil lighting system and comprises
a method of distributing the oil and means whereby common oil of this kind
can be burned with absolute safety at the burners and without the use of taps.
In carrying my invention into effect I proceed in or about the following manner
making reference to the accompanying drawings wherein Fig. 1, is a section of
the general arrangement of parts constituting the system; Fig. 2, a section
of a modified form of feed regulator; Fig. 3, a section of a valve for shutting off
the supply of oil to the feed regulators and Fig. 4, a section of a chandelier for
use in connection with this system of lighting. Referring to Fig. 1 the paraffin
oil is stored in a lower reservoir a from which it is transferred to an upper
reservoir through the pipes c and d by operating the pump e.
From the
reservoir the oil passes by the pipe f to the regulator g and from thence by
the pipe to the oil holder i carrying the burner 7. One regulator g may be
employed with any number of pipes and burners . The regulator 9 consists
of a receiver within which is free to move easily up and down a float vertically
through the center of the float & is passed the tube 7 prolonged somewhat below
the bottom of the float and provided with a screw cap m having within it a
seating of rubber, leather, cork or other suitable material. The tube 7 is
provided with two small inlet holes close to the screw cap. The end of the feed
pipe passes downwards through the tube / and is of such length that the seat-
ing n will not come in contact with the end of f until the float k has risen to the
predetermined height for cutting off the supply of oil to the regulator g. A
rounded end is fitted to the end of the feed pipe f and the exit aperture of the
rounded end is of small diameter. the diameter being adjusted to suit the number
of burners and the quantity of oil required for use and the pressure. The action
of the regulator g is as follows assuming it first of all to be empty As the oil
enters through f the float k rises and brings the seating n in contact with the
end off and so shuts off the supply and as the oil in the oil holder i is consumed

page_text: the float will fall and remove the seating n away from the end of f and so again
establish the flow or feed of the oil to the regulator g. In the regulator shown in
Fig. 2 the rise and fall of the float (caused by the supply and consumption
of the oil) operate the outer ends of levers o pivotted to levers p below the float k
and also to brackets g. The inner ends of the levers o are movably attached to a
plunger faced on its lower end with rubber, leather, cork or other suitable
materials which rests on the end of the feed pipe f¹ and cuts off the supply when
the float has risen sufficiently the exit on feed pipe f being made as described
in connection with f of Fig. 1. To enable the supply of oil to the feed regulator
to be shut off when necessary I employ any suitable kind of valve of which
Fig. 3 shows a convient form. In this valve the oil enters the casing t by the
pipe and within the casing is a plunger u working in the cylinder v into which
opens the inlet end of the pipe leading to the feed regulator g. The plunger u
is faced at w with rubber, leather, cork or other suitable material. The faced
end is kept in contact with the end of the feed pipe h by the action of the spiral
spring and when the supply is to be established between the upper reservoir b
and the feed regulator g the plunger is raised and kept so by a bell crank
lever, weight, screw or other means. The chandelier shown in Fig. 4, comprises
a regulator provided with a float and other parts as already described and
having radial or other pipes for supplying oil to the oil holders . The
regulator is attached to the lower end of a tube y to the upper end of which
are attached the inner ends of the chains z passing over pullies A attached to
the supporting tube B the outer ends of the chains being provided with the
balance weights C. The supply pipe D passes freely through the cup and ball
joint E of the tube B so that this tube can revolve round it. Upstanding from the
bottom of the tube y is another tube I containing mercury or some other suitable
substance heavier than oil and so adjusted as to balance the arrangement and
confine the oil to the supply pipe D. Passing through the bottom of the tube y
is the feed pipe F2 which passes upwards within the supply pipe D and downwards
into the regulator g². In all the above arrangements the size of the aperture in
the feed pipe opening into the regulator is adjusted to suit the pressure and
quantity of oil required for use.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
1st. For use in the paraffin oil lighting system above described for accom-
modating the feed of oil to the consumption at the burners, a feed regulator
consisting essentially of a reservoir within which is free to slide up and down a
float having a central tube free to slide up and down over the feed end of the feed
pipe, and having a cap at the bottom of the prolonged bottom end of the said
central tube the said cap being provided with a rubber, leather, cork or other
seating which closes or opens the exit end of the feed pipe in accordance with
the upward and downward movements of the float, the exit aperture of the said
feed pipe being of small diameter, and the diameter being adjusted to suit the
pressure and quantity of oil required for use substantially as described in the
above specification and exemplified in Fig. 1, of the accompanying drawings.
2nd. For use in the paraffin oil lighting system described above a feed regulator
for accomodating the feed of oil to the consumption at the burners and consisting
essentially of a receiver within which is free to move up and down a float having
on its under side hangers which operate pivotted levers, the inner ends of which
levers are movably attached to a plunger having a rubber or other facing which
closes or opens the exit end of the feed pipe in accordance with the rise and fall
of the said float, the exit aperture of the said feed pipe being of small diameter
and the diameter being adjusted to suit the pressure and quantity of oil required
for use substantially as described in the above specification and exemplified by
Fig. 2, of the accompanying drawings.

page_text: 3rd. For use in the paraffin oil lighting system described above to interrupt the
flow of oil from the upper reservoir to the feed regulator a valve consisting
essentially of a casing with an inlet for the oil and having upstanding from its
bottom a cylinder through which is passed the exit end of the feed pipe, on which
end rests the rubber, leather, cork or other faced lower end of a plunger free
to move up and down in the said cylinder and having its upper end surrounded
by a spiral spring for the purpose of keeping its lower end in contact with the
said exit end of the said feed pipe until removed therefrom by drawing up the
plunger and retaining it in a raised position substantially as described in the
above specification and exemplified by Fig. 3 of the accompanying drawings.
4th. For use in the paraffin oil lighting system described above a chandelier
