Burners for Lighting and Heating.
I, 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 my invention is to supply burners for heating and lighting with a
duly regulated supply of oil when the said burners are lit, and to prevent any overflow
of the oil, whether the burners be lit or not.
I effect this in the following manner.
The supply of oil is above the-burner, or else under pressure, which is equivalent to
being above the burner.
The pipe supplying the oil to the burner dips into a well partly filled with any
suitable liquid of greater specific gravity than the oil. The level of the oil in the
burner cup is dependent on (a) the relative specific gravities of, the liquid-heavier
than the oil-in the well, and the oil; (b) the depth of immersion of the oil pipe in
the said heavier liquid in the well; and (c) the height or pressure of the oil supply.
The amount of oil supplied is dependent on the consumption of the burner or burners.
The annexed drawings will shew the nature of my invention.

In Fig. 1 an overhead tank of oil a, supplies the burner cups b and c, by means of
the pipe d. The pipe d, dips into the well which contains mercury f. The
immersion of the pipe d, is duly proportioned to the relative specific gravities of
mercury and oil, which-in the case of ordinary petroleum-is about 17 to 1.
When the oil g, is at such a level in the burner cups b and c, as, with the mercury
in the well e, to balance the column of oil in the pipe d and tank a, no flow of oil will
ensue until consumption by the burners calls for a further supply.
The oil is indicated by vertical dotted lines, and the mercury by horizontal dotted
lines.

The pipe d, and well e, are as before described. The screws and nuts i and, are
for adjusting the immersion of the piped in the mercury.

page_text: The cams kand 1, are to act as a turn-off motion, when the burners are not lit, or
when the wicks are being renewed. This turn-off is effected by the increased
immersion of the pipe d in the mercury.
Water, or other liquids heavier than oil, may be used in the well e, instead of
mercury; but the well must then be much deeper, on account of such liquids being of
less specific gravity than mercury.
This invention is specially suitable for use in combination with that described in my
specification No. 3067 of A.D. 1887; as, by such a combination, burners on any
number of varying levels can be supplied from one central reservoir of oil on an
automatic system.
Each burner may be fitted with a separate arrangement of dipping-pipe, well, and
mercury or other suitable liquid-or, such arrangement of dipping-pipe, well, and
mercury or other suitable liquid-may feed a number of burners; so long as such
burners are on one level.

Improvements in Appliances for Supplying Hydrocarbon Oils to
Burners for Lighting and Heating.
I, JOSEPH BEVERLEY FENBY, of Sutton Coldfield, in the County of Warwick, Civil
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:—
The object of my invention is to supply burners for heating and lighting with
a duly regulated supply of oil when the said burners are lit, and to prevent any
overflow. of the oil, whether the burners be lit or not.
I effect this in the following manner.
The supply of oil is 'above the burner, or else under pressure, which is equivalent
to being above the burner.
The pipe supplying the oil to the burner dips into a well partly filled with
mercury which is of greater specific gravity than the oil. The level of the oil in the
burner cup is dependent on: (a) the relative specific gravities of, the liquid-heavier
than the oil-in the well, and the oil; (b) the depth of immersion of the oil pipe in
the said heavier liquid in the well; and (c) the height or pressure of the oil supply.
The amount of oil supplied is dependent on the consumption of the burner or
-burners.
The drawings accompanying the Provisional Specification together with the
drawing accompanying this Complete Specification shew the nature of my invention.
In Fig. I an overhead tank of oil a supplies the burner cups b and c by means of
the pipe d.
The pipe d.dips into the well e, which contains mercury f. The immersion of the
pipe d is duly proportioned to the relative specific gravities of mercury and oil, which
in the case of ordinary petroleum-is about 17 to 1. That is to say, the depth of
immersion of the pipe d in the mercury is about one seventeenth of the head of oil
in the tank a measured from the desired oil level in the burner cups b and c.
I
When the oil is at such a level in the burner cups b and c, as, together with the
mercury in the well e, to balance the column of oil in the pipe d and tank a, no flow
of oil will ensue until consumption by the burners calls for a further supply.
The oil is indicated by vertical dotted lines, and the mercury by horizontal dotted
lines.
Fig. II shews an arrangement for feeding two lights from the overhead pipe .
The pipe d, and well e, are as hefore described.
The screws and nuts, i and 7, are for adjusting the immersion of the pipe d in the
mercury by raising or lowering the well e.
The cams and are to act as a turn-off motion, when the burners are not lit, or
when the wicks are being renewed.
This turn-off is effected by the increased immersion of the dipping pipe d in the
mercury f

page_text: Fig. III, on the drawing accompanying this Complete Specification, shews a two
light pendant supplied with oil from an overhead pipe a. A vertical pipe d leading
from the pipe a dips into a well e, containing mercury f. The level of the oil in the
burner cups b and c is regulated and governed by the depth of immersion of the oil
pipe d in the mercury fand the head or pressure of the oil in the pipe d.
A plunger g is provided for regulating the level of the mercuryf. This plunger g
is raised or lowered by turning the milled head g', which is fixed to the plunger g;
the plunger rises or falls on the screwed sleeve h according as the milled head g¹ is
turned to the left or right.
When the plunger gis lowered the level of the mercuryf is raised and consequently
the oil is fed to a lower level in the burner cups b and c.
When the plunger g is raised the level of the mercury f is lowered and the oil
consequently is fed to a greater height in the burner cups and c.
The plunger g may be raised or lowered by any other mechanical contrivance
such as a cam or lever, and may be of any sectional form as its only purpose is to
raise or lower the level of the mercury.
This invention is specially suitable for use in combination with that described in
my specification No. 3067 of A.D. 1887; as, by such a combination, burners on
any number of varying levels can be supplied from one central reservoir of oil on
an automatic system.
Each burner may be fitted with a separate arrangement of dipping pipe, well,
and mercury-or, such arrangement of dipping pipe, well, and mercury-may feed
a number of burners; so long as such burners are on one level.
Having now particularly described and ascertained the nature of my said Inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is
1. Regulating and governing the level of the oil in the burner cup of a lamp by
immersing the mouth of the oil supply pipo more or less deeply in mercury, as described
and illustrated.
2. Regulating the depth of immersion of the oil supply-pipe-in-the mercury, by
raising or lowering the mercury well while the pipe remains stationary as described
and illustrated.
3. Regulating the depth of immersion of the oil supply pipe by raising or lowering
the level of the mercury, by immersing a plunger more or less deeply in it as described
and illustrated.
