1 JOHN ROBERTS, 22 High Street Cleator Moor, in the County of Cumberland
Tinsmith do hereby declare the nature of this invention to be as follows:--
The Invention has for its object a safe Oil Vase or Vessel for Household and other
lamps that is, a Lamp Vessel containing Petroleum, Paraffin, or other burning
Oil which is rendered perfectly safe from taking fire from the burner, and thereby
exploding.
The Invention is made as follows:--
A tube is made to shape of wick whether round, flat, or otherwise, as the case may
be to pass through the Vase from the top of Vase to the bottom of the oil. The
top is secured to the Vase, the bottom end I prefer to close; with the exception of a
small hole for oil to pass into the tube-The wick is cased so as to prevent the fire
igniting the gas that generates on the surface of the oil in the Vase.
Dated this Twenty eighth day of September 1887.

Tinsmith 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 invention has for its object the securing from explosion or accidental com-
bustion or liability thereto of the oil or spirits contained in oil or spirit lamps or
lanterns or contained in oil or spirit stoves or contained in other vessels where the
means of giving light or heat are the burning of a liquid by means of a wick. The
means adopted are as follows. A tube A whereof the bottom is closed is either
affixed to the neck of the reservoir E (in which case such tube has preferably sides
or wings entirely closing the rest of the neck F) or attached to the burner G or made
part of the burner or otherwise connected with the neck or upper portion of the
reservoir. This tube passes through the reservoir or oil vessel almost to the bottom
of such reservoir and contains the wick C or portion of the wick. Oil is admitted to
the tube, and thus to the wick) by a small hole B or a series of small holes punctured
in the bottom or lower portion of such tube. The tube may be made of any variety
of shape to suit circumstances and of any material including gauze and perforated
metal and more tubes than one may be used or the tube may have divisions for or
contain more than one wick.
The enclosure and consequent isolation of the wick by means of the tube prevents
access of flame to the oil D and entirely eliminates the liability to explode to which
ordinary lamps &c. are subject. Further if the lamp is overturned the oil from the
reservoir no longer passes through the burner into the flame and additional safety is
thus secured.
In some cases gauze or perforated metal is preferably used and in others by reason
of different means of supplying the oil the tube may not actually pass through the
reservoir but only touch or impinge the same.
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 use of a tube to enclose or partly enclose the wick and thus shield the same
from the liquid contained in the vessel or in other words the encasing of the wick in
a tube instead of subinerging the naked wick in the liquid.
The tube is submerged and oil is admitted by puncture or perforation in the
tube.
The tube may be made of any suitable material or shape and may be affixed either
to the upper or lower portion of the lamp or vessel or connected between the reservoir
and the burner in any suitable way and such tube may be perforated or punctured
either at the end or side.
The invention may be used with all manner of oil or spirit lamps lanterns or stoves
and in respect of either vegetable or mineral oils or of spirit.
