I JAMES SMITH of Pine Street, Darwen in the county of Lancaster Brass Finisher
do hereby declare the nature of this Invention to be as follows:-
My invention consists in supplying one or more lamps with oil from a cistern which
can be placed at a higher level than the lamp or lamps which it supplies, and still be
self feeding or automatic.
From the supply cistern which is made airtight, I carry a supply tube or tubes to
the lamp or lamps being supplied, these lamps consist of a small vessel (for the wick)
and on to which the lamp burner screws.
I also carry an air tube from the top of the supply cistern to the lamp vessel, this
tube may pass either within the oil supply tube or outside it; by this arrangement a
to the level of its air tube, within
constant supply of oil is carried to the lamp vessel
the lamp verrel or at any other convenient position I place a valve or tap for use only
when filling the supply cistern to prevent the oil running out; by this arrange-
ment, I have an oil lamp with no more underneath shadow than ordinary gas
pendants.
Dated this Twenty-fifth day of November 1887.

A is the oil supply cistern which when in working order is air tight, I carry an air
supply tube B or tubes to the lamp or lamps being supplied, the lamps consist of a
small vessel C (for the wick D and oil) and on to which the lamp burner E screws. I
also carry an oil tube F within the outer air tube B from the bottom of the supply
cistern A, to the lamp vessel, the air tube may pass either within the oil supply tube or
outside it, by this arrangement a constant supply of oil is carried to the lamp vessel up
to the level of its air tube.
Within the lamp vessel or at any other convenient position I place a valve, screw or
tap H to stop the oil supply to the lamp by blocking up the oil tube for use only when
filling the supply cistern A to prevent the oil running out or overflowing, by the above
arrangement of only one visible tube connecting the oil supply and the lamp I have
an oil lamp with no more underneath shadow than ordinary gas pendants.

page_text: 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:
1. In oil lamps the use and employment of air supply tubes from the cistern to the
lamp, one being within the other, and either of which may be used for air or oil supply
as and for the purposes shown and described.
2. The use and employment of the screw, valve or tap, to shut off the oil supply
from the lamp when refilling, substantially as shown and described.
3. The general arrangement and construction of oil or paraffin lamps substantially
as shown and described.
