Improvements in Apparatus for Supplying Oll to Oil Lamps and
Means of Controlling same.
:
We, JOHN ROYLANCE, Tin Plate Worker, and JOHN HOYLE, Pattern Designer,
both of Micklehurst, Mossley, in the County of Chester, do hereby declare the
nature of this invention to be as follows:-
This invention relates to the construction and arrangement of apparatus for
supplying petroleum or other mineral oils to one or more oil lamps, the object of
ур to
the invention being to keep such lamp or lamps constantly supplied with oil
the required level.
In carrying out our invention and in the case of a series of lamps supported by a
chandelier or pendant from the ceiling of the room or other place. requiring to be
lighted we employ a cistern or vessel which surrounds and is supported by the
vertical pipe of such chandelier and is designed to contain the main supply of oil.
The orifice or opening through which this supply cistern is filled is provided
with a sieve or perforated pocket to prevent any extraneous matter getting into
the cistern.
Below the cistern and around the same vertical pipe we affix a small reservoir,
fitted with a ball float valve, which communicates with the cistern above by means
of the vertical pipe. This reservoir which is formed in halves to facilitate the
fixing of the ball float valve is on a level with the several lamps and communicates
therewith by means of the supporting arms of the chandelier.
It will therefore. be apparent that as soon as the oil in the reservoir and lamps
reaches the desired height the rising of the float in the former, will close the valve
and prevent the admission of any more oil whilst as the oil is consumed and the
level sinks, the sinking of the float will open the valve and admit a fresh supply..;
Between the supply cistern and the reservoir beneath we insert a stop cock or
5. tap for shutting off the supply of oil when desired.
►
--
The vertical pipe is. either formed in sections connecting the cistern and
reservoir together or formed in one and perforated to allow of the oil passing from
one vessel to another.
These improvements are equally applicable to a single lamp bracket the cistern
9 and reservoir being placed against the wall or partition from which the bracket
branches.

Improvements in Apparatus for Supplying Oil to Oil Lamps and
Means of Controlling same. .
We, JOHN ROYLANCE, Tin Plate Worker and JOHN HOYLE Pattern Designer
both of Micklehurst, Mossley in the County of Chester, do hereby declare the
40 nature of our said invention and in what manner the same is to be performed, to-be
particularly described and ascertained in and by the following statement:-
This invention relates to the construction and arrangement of apparatus for
“supplying “petroleum or other mineral oils to one or more oil lamps, the object of

this invention being to keep such lamps constantly supplied with oil up to the
required level.
In carrying out our invention and in the case of a series of lamps supported by
a chandelier from the ceiling of a room or other place requiring to be lighted we
employ a cistern or vessel which surrounds and is supported by the vertical pipe
of such chandelier and which contains the main supply of oil.
Below the said cistern we affix a small reservoir into which the oil runs from the
cistern above under the control of a ball float valve which reservoir is situated on
a level with the several lamps and communicates therewith through the hollow
arms of the chandelier. As the oil runs into the reservoir and from thence to the
several lamps and reaches the desired height the rising of the ball float closes the
valve and prevents the admission of more oil whilst as the oil is consumed and
the level sinks the sinking of the float will open the valve, admit a fresh supply
and thus always keep the lamps supplied with oil up to the desired height.
In order that this our said invention may be more readily understood and
carried into practical effect we have hereunto annexed a sheet of drawings
illustrative of our improvements and we will now proceed to describe the same
with the assistance of the various figures and letters of reference marked thereon.
Fig. 1 is an exterior view and Fig. 2 a sectional view of a chandelier constructed
in accordance with our invention.
A designates the cistern or vessel containing the main supply of oil which is
made of thin sheet metal and is secured to the vertical pipe B of the chandelier.
A loose lid C encloses the top of the vessel A which is raised out of the way when
it is required to fill the cistern with oil.
D is the reservoir arranged beneath the cistern A within which a ball float E
and plug cock or valve El is situated; for the fixing and adjustment of which the
reservoir D is formed in halves and screwed together at F. The oil from the
cistern above flows through the small pipe or tube G under the control of
the valve E¹.
The flow of the oil is also controlled by the stop cock E. The lamps H are
supported by the hollow arms I and are situated on a level with the reservoir D.
Oil being supplied to the cistern and the stop cock E being opened the oil
immediately flows through the tube G into the reservoir D and from thence to the
several lamps through the arms I. As soon now as the oil reaches the ball float,
the latter commences to rise and gradually closes the plug cock and eventually
shuts off the further supply of oil as soon as the desired level has been reached.
As the oil is consumed and the level of the oil sinks the sinking of the float opens
the plug cock again and thus admits a fresh supply of oil,
.
In this way the several lamps are automatically supplied with oil up to the
required level and that for a considerable length of time and thus the labor of
filling each lamp separately and at frequent intervals is avoided.
The orifice or opening through which the cistern is filled may be fitted with a
sieve or perforated pocket to prevent any extraneous matter getting into the
cistern. The opening in the pipe B which leads to the tube G is covered by a
sieve B¹ to prevent dirt or sediment in the oil finding its way into the. reservoir.
Each lamp is provided with its own extinguishing or regulating devices and thus
all or only one of the lamps may be lighted.
These improvements are equally applicable to a single lamp bracket the cistern
and reservoir being placed against the wall or partition from which the bracket
r projects.
Having thus particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
The use and employment of a cistern or vessel surrounding the vertical pipe of
an oil-lamp chandelier or pendant in combination with a reservoir fitted with a ball
