page_text: Improvements in or relating to Oil Lamps.
I, ARTHUR BROADBENT, of 312, Bridge Street West, Birmingham, in the
County of Warwick, Lamp Manufacturer, do hereby declare the nature of this
invention to be as follows:-
This invention is especially applicable to the ordinary paraffin lamp.
Its object is to prevent accidents caused by the lamp overturning and the oil
spilling.
This object I attain by the arrangement as hereinafter set forth viz.:-
Instead of the oil being contained all in one vessel; it is contained in two
vessels, i.e. there is a small or wick vessel placed inside the large one, the large
vessel being used as a reservoir and the small vessel for the immediate supply
of the wick; there is also a cavity above the small vessel, for containing the oil
when the lamp is upset, and in the centre of this cavity over the wick vessel is
a suitable tube which acts similar to the tube in a safety ink bottle, when it
is upset; the two vessels are arranged as follows viz. there is a division in the
vessel sufficiently far down to allow space at top to contain the oil in the wick
vessel when the lamp is upset; the wick vessel is attached to, and forms part of
this division, and extends down into the reservoir, leaving sufficient space for
the mechanism to work which operates the valve in the bottom.
The valve is closed by a disc, attached to a rod which has attached at the
opposite end a weight, this is hung on suitable bearings immediately beneath
the valve, in such a manner that when the lamp is tilted, the weight hanging
out of the perpendicular causes the disc to press against the valve and so
closes it.
For the purpose of admitting air into the reservoir as the oil is being con-
sumed I provide a valve in the top of the oil vessel, and the valve is closed by
a similar arrangement to that which operates the valve and the wick vessel
when it is upset.
Thus it will be perceived that the oil is supplied to the reservoir through an
outer screw feeder, and that as it rises in the reservoir, it finds its way through
the valve at the bottom of the wick vessel; until it is sufficiently full, and the
air valve supplies it with the necessary quantity of air.
When the lamp is upset the oil in the wick vessel, rushes into the cavity left
for the purpose, and the weighted rod being thrown out of the perpendicular
causes the disc to press against the valve and so closes it, and prevents any more
oil entering the said wick vessel.
The air valve also operating in a similar manner at the same time.

page_text: I, ARTHUR BROADBENT, of 312, Bridge Street West, Birmingham, in the
County of Warwick, Lamp Manufacturer, 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:
-
This invention is especially applicable to the ordinary paraffin lamp.
Its object is to prevent accidents caused by the lamp overturning and the oil
spilling.
This object I attain by the arrangement as hereinafter set forth viz.:-
Instead of the oil being contained all in one vessel it is contained in two
vessels, i.e. there is a small or wick vessel placed inside the large one, the large
vessel being used as a reservoir and the small vessel for the immediate supply
of the wick; there is also a cavity above the small vessel for containing the oil
when the lamp is upset.
In the centre of this cavity over the wick vessel is a suitable tube which acts
similarly to the tube in a safety ink bottle when it is upset.
The two vessels are divided as represented in the accompanying drawing.
A" shews the upper vessel which contains the oil flowing from the lower or
wick vessel "B" as indicated by arrows when the lamp has been overturned.
This wick vessel "B" is attached to and forms part of the upper division "A,"
it extends down into the ordinary reservoir "D" as shewn, leaving sufficient
space for the mechanism to work which operates the valve at bottom marked "C."
This valve is closed by a disc or ball attached to a rod which is weighted at
the opposite end, this is hung upon suitable bearings immediately beneath the
valve in such a manner that when the lamp is tilted the weight hanging out of
the perpendicular causes the disc or ball to press up against the valve "C" so
closing it.
For the purpose of admitting air into the reservoir as the oil is being con-
sumed I provide a valve in the top of the oil vessel marked "E" in the draw-
ing and this valve is closed by an arrangement similar to that which operates
the valve in the wick vessel thus shutting off the air, and preventing a further
flow of oil into the upper vessel "A" when the lamp is overturned.
The oil is supplied to the ordinary reservoir "D" by means of an outer screw
feeder, and as it rises in this reservoir it finds its way through the valve at the
bottom of the wick vessel until it is sufficiently full, the air valve "E" supply
ing it with the necessary air.
The lamp being upset the oil in the wick vessel flows into the upper vessel
and the weighted rod being thrown out of the perpendicular causes the disc or
ball to press against the valve so closing it and preventing the upward flow
from the ordinary reservoir "D" into the said wick vessel.
The air valve "E" operates similarly and at the same time.
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:
Novel devices substantially as herein shown and described.
Firstly a vessel constructed so as to contain the lamp wick with just sufficient
oil to feed the flame.

page_text: Secondly a chamber situated in the upper part of the lamp reservoir designed
so as to receive the overflow of oil when lamp is upset.
Thirdly valves constructed to exclude further supply of oil to the wick
chamber and air from the flame when lamp is upset.
