Year: 1881

Invention of "IMPROVEMENTS IN THE METHOD OF AND APPARATUS FOR
SUPPLYING LAMPS WITH PETROLEUM AND OTHER OIL."
PROVISIONAL SPECIFICATION left by the said John Wilby at the Office of
the Commissioners of Patents on the 26th September 1881.
JOHN WILBY, of Barnsley, in the County of York. "IMPROVEMENTS IN THE
METHOD OF AND APPARATUS FOR SUPPLYING LAMPS WITH PETROLEUM AND
OTHER OIL."
This Invention consists in a new method of supplying lamps with oils in regular
and uniform quantities, without disturbing the said lamp or interfering with the
wick. For this purpose I employ a vessel containing oil at some distance above
the lamp. This vessel is connected by a pipe to a small tube containing both wick
and oil, such oil being supplied thereto continuously by the said pipe in the same
proportion as it is consumed, so that as long as there is oil in the vessel the wick
will be supplied; suitable tops are provided for opening and shutting off the supply
of oil. By this arrangement any number of wicks may be supplied with oil from
the same vessel.

by the said John Wilby in the Great Seal Patent Office on the 25th March
1882,
JOHN WILBY, of Barnsley, in the County of York. "IMPROVEMENTS IN THE
METHOD OF AND APPARATUS FOR SUPPLYING LAMPS WITH PETROLEUM AND
OTHER OIL."
This Invention consists in a new method of supplying lamps with oils in regular
and uniform quantities, without disturbing the said lamps or interfering with the
wick. For this purpose I employ a vessel containing oil, and a valve placed in an
elevated position above the lamp. This vessel is connected to another vessel and 1
receives oil therefrom as and when required, such oil being fed or conducted
continuously by a horizontal pipe to the lamps containing wick. The oil is fed to
the wick in the same proportion as it is consumed, so that as long as there is oil in
the upper vessel the wick will be supplied.
---In-order-that-iny improvements may be more fully understood, I herein give
__reference to the accompanying Sheet of Drawings,-wherein Fig. 1 is elevation of a
lamp constructed according to my Invention, and Fig. 2 is section of samo. A is a
vessel having a reck or contracted part B, provided with a stopper or valve-C-and.
vertical rod D. The neck of this vessel is placed in another vessel E, which
receives the oil and supplies it by the pipe F tó lamps G. It will be seen that as
long as there is sufficient oil in the vessel E, as reaches the horizontal pipe F, that
such oil will pass through perforations made in the pipe, and will be fed con-
tinuously with oil so that the lamps and, wicks do not get disturbed, but will be
supplied a long time according to the amount of oil in the upper vessel.
In constructing this lamp it is necessary in placing the upper vessel into the
lower vessel to turn the said upper vessel neck downwards, and in doing so the oil
would be spilt, but to prevent this I employ the stopper or valve C with the
vertical rod D, which is sufficiently long as to reach the bottom of the lower vessel
and thereby lift up the valve, as shewn in the Drawings, so that the oil can escape
therefrom.
Having thus described the nature of my said Invention, and shewn by Drawings
how the same is to be performed or carried into practical operation, I would have
it understood that I do not confine myself to the precise details of construction and
arrangement as herein set forth, but what I claim as of my Invention is,-
The combined use of the two vessels A and E, for the purpose of supplying lamps
with oil in manner substantially as herein shewn and described.
In witness whereof, I, the said John Wilby, have hereunto set my hand and
seal, this Twenty third day of March, in the year of our Lord One thousand
