1 JOSEPH BEVERLEY FENBY, of Sutton Coldfield, in the County of Warwick,
Civil Engineer, do hereby declare the nature of this invention to be as follows:-
The object of this invention is to raise hydrocarbon oils by the pressure of water,
so regulated that the oil shall maintain a constant level, for the supply of any desired
number of burners. This invention does not apply to self-contained or portable
lamps.
I will describe the application of my invention to the lighting of a house. In the
cellar, or other suitable place, a closed vessel is provided to hold a store of oil. From
the upper part of this vessel a pipe leads upwards to carry oil to the burners, and this
pipe is branched off to each burner, as is done with pipes for gas. From the upper
part of the closed oil vessel a second pipe rises. This is the water pipe. This water
pipe terminates at its upper end in a small water tank. In this small tank the water
is. kept at a constant level, by means of a ball cock, or equivalent appliance. The
water colunin requires to be about four fifths of the oil column in height; that is, in
inverse proportion to the specific gravities of oil and water. As the burners consume
the oil, water passes into the closed oil vessel, and a constant level of oil is maintained
at the burners. The arrangement described will supply oil to any number of burners
on one level.
In cases where different levels are to be supplied, the arrangement is made
separately for each level.
This arrangement is suitable for lighting and heating.

the same is to be performed, to be particularly described and ascertained in and by
the following statement :-

I will describe the application of my invention to the lighting of a house. In
the cellar, or other suitable place, a closed vessel is provided, to hold a store of oil.
From the upper part of this vessel a pipe leads upwards to carry oil to the burners,
and this pipe is branched off to each burner, as is done with pipes for gas.
From the upper part of the closed oil vessel a second pipe rises. This is the water
pipe.
This water pipe terminates at its upper end in a small water tank. In this small
tank the water is kept at a constant level, by means of a ball 'cock or equivalent
appliance.
The water column requires to be about four-fifths of the oil column in height;
that is, in inverse proportion to the specific gravities of oil and water.
As the burners consume the oil, water passes into the closed oil vessel, and a
constant level of oil is maintained at the burners.
The arrangement described will supply oil to any number of burners on one level.
In cases where different levels are to be supplied, the arrangement is made
separately for each level.
This arrangement is suitable for lighting and heating.
The accompanying drawing shews a sectional elevation of a lighting apparatus made
according to my invention.
A is the closed oil vessel. B is the oil pipe for supplying the oil cups C into
which the burners fit. D is the water pipe, connected to the ball cock cistern E.
The lower end of the pipe D reaches nearly to the bottom of the well F. B and D
are fitted with stopcocks g and h, and the oil vessel A has a cock at i for draining off
the water when necessary. At j is a screw cap closing the opening through which
the oil vessel A is filled with oil. The horizontal broken lines indicate water, and
the vertical broken lines indicate oil. The single headed arrows shew the course of
fhe water, and the double headed arrows that of the oil.
The vessel A being empty, the apparatus is charged as follows.

page_text: The stopcock g is kept closed, and the drain cock i is opened. Then the stopcock h
is opened, to allow water to fill the well F. As soon as water begins to run from the
cock the stopcock is turned off, and i is also closed. The vessel A is then filled
with oil through the opening at j, and the cap jis screwed on. The two stopcocks g
and are then opened, and the water pressure forces the oil up to the burner cups.
The water will now automatically supply the burners with oil as the consumption
requires, because such consumption tends to upset the hydrostatic balance of the two
columns or heads of oil and water.
The purposes of the well F are twofold; namely, first to neutralise that part of the
water pipe D which is within the well, so that the effective water column shall
be constant, and in no way dependant on the varying amount of water in the
vessel A; and, secondly to prevent any oil from ascending to the cistern E.
•
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 :—
The improved appliances for supplying hydrocarbon oils to burners, as described
and illustrated.
