IMPROVE- MENTS IN LAMPS FOR BURNING BENZOLINE AND SUCH LIKE LIQUIDS
Year: 1885

page_text: I WILLIAM HARDY the younger of Thistleton, Oakham, in the County of
Rutland, Farmer, do hereby declare the nature of my invention for "IMPROVE-
MENTS IN LAMPS FOR BURNING BENZOLINE AND SUCH LIKE LIQUIDS" to be as
follows:-
According to my invention in order to allow of such lamps being used with
perfect safety I form the reservoir of the lamp of a globular form with a flat bottom
heavily weighted so that the lamp cannot be readily upset and cannot remain lying
on its side even if it be upset.
The top of the lamp which carries the wick tube and which usually screws on
I solder down and I make the shield which holds the cotton wool in its place
extend to the bottom of the lamp and so allow the wick to go to the bottom.
The
shield I have soldered to the top and leave its upper part say for about one inch
unperforated so that should the lamp be filled beyond saturation of the cotton wool
and be upset no liquid will flow from it.
In this way I remove one of the chief dangers arising from the present lamps and
that is, that if the lamp be dropped the screw top usually gives way owing to its
not being properly screwed on and then the oil pours out for even if the lamp is
filled with cotton wool the lamps are frequently filled with such a quantity of oil
that the wool cannot hold it.
The wick can be inserted into the wick tube from the top and the lamp can be
filled from the side through an opening closed by a screw cover.
The wick may be
raised and lowered in the ordinary way by turning a small spindle and as the top
has not to be taken off to fill the lamp the turn up does not get out of order as the
wick remains straight and does not get twisted with continually screwing and
unscrewing of the top as also the wick is in this way prevented from becoming
buckled its capillary action always remains unimpaired.
For cheap lamps a slide for regulating the flame may be used. In order to at
once put out the light should the lamp be upset I surround the wick tube with
another tube which is perfectly loose so that a very small movement of the lamp
sideways will cause the loose tube to slide along the wick tube and put out
the light.
To prevent the loose tube falling off altogether it is connected to the lamp by a
piece of chain.

Improvements in Lamps for Burning Benzoline and such like
Liquids.
I WILLIAM HARDY the Younger of Thistleton Oakham in the County of
Rutland Farmer do hereby declare the nature of my invention for "IMPROVE-
MENTS IN LAMPS FOR BURNING BENZOLINE AND SUCH LIKE LIQUIDS" and in what
manner the same is to be performed to be particularly described and ascertained in
and by the following statement :—
According to my invention in order to allow of such lamps being used with
perfect safety I form the reservoir of the lamp of a globular form with a flat bottom
heavily weighted so that the lamp cannot be readily upset and cannot remain lying
on its side even if it be upset.
The top of the lamp which carries the wick tube and which usually screws on
I solder down and I make the shield which holds the cotton wool in its place
extend to the bottom of the lamp and so allow the wick to go to the bottom―The
shield I have soldered to the top and leave its upper part say for about one inch
unperforated so that should the lamp be filled beyond saturation of the cotton wool
and be upset no liquid will flow from it.
In this way I remove one of the chief dangers arising from the present lamps
and that is, that if the lamp be dropped the screw top usually gives way owing to
its not being properly screwed on and then the oil pours out for even if the lamp is
filled with cotton wool the lamps are frequently filled with such a quantity of oil
that the wool cannot hold it.
The wick can be inserted into the wick tube from the top and the lamp can be
filled from the side through an opening closed by a screw cover.
The wick may be
raised and lowered in the ordinary way by turning a small spindle and as the top
has not to be taken off to fill the lamp the turn-up does not get out of order as the
wick remains straight and does not get twisted with continually screwing and
unscrewing of the top as also the wick is in this way prevented from becoming
buckled its capillary action always remains unimpaired.
In order to at once put out the light should the lamp be upset I surround the
wick tube with another tube which is perfectly loose so that a very small movement
of the lamp sideways will cause the loose tube to slide along the wick tube and
put out the light.
To prevent the loose tube falling off altogether it is connected to the lamp by a
piece of chain.
Figure 1 of the Drawings hereunto annexed shows a side elevation and Figure 2
a vertical section of a lamp constructed as above described.
A is the reservoir of the lamp made somewhat of a globular form with a flat
bottom heavily weighted-B is the shield which I make to extend down from the
top of the reservoir to the bottom-B' are perforations in the lower half of the
shield the upper half being left unperforated for the purpose described above-0 is
the top of the lamp which carries the wick tube D and which is soldered on to
the bowl-E is the spindle for raising or lowering the wick in the wick tube-F is

page_text: a
a tube which slides very loosely over the exterior of the wick tube to extinguish
the flame should the lamp be thrown over on its side-G is a light chain to couple
this tube to the spindle E.
H is a screw cap closing an opening through which the reservoir can be filled-
I is a filling of cotton wool filling the space between the sides of the reservoir and
the shield B.
I also provide the usual small cap for preventing evaporation and smell when
not in use which fits on the top of the outer tube and is attached as usual with a
small piece of chain.
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. The construction of the reservoir of lamps for burning benzoline and such
like liquids of a globular form with a flat bottom heavily weighted, substantially
as described.
2. Carrying the inner shield B down to the bottom of the reservoir and
perforating its lower portion only, substantially as described.
3. Surrounding the exterior of the wick tube with a loose tube F to extinguish
the lamp should the lamp be upset.
4. The construction of lamps for burning benzoline and such like liquids substan.
tially as described.
Dated this 20th day of August 1885.
