IMPROVEMENTS IN LAMPS FOR BURNING GASOLINE, ALBO-CARBON, PARAFFIN OR OTHER LIQUIDS
Year: 1884

page_text: We ALFRED DAVID TURNER of 34 Rippoth Road Old Ford in the County of
Middlesex Engineer and WILLIAM FLATAU of Lusan House, Highbury Quadrant
in the same County Gentleman do hereby declare the nature of our invention for
IMPROVEMENTS IN LAMPS FOR BURNING GASOLINE, ALBO-CARBON, PARAFFIN OR
OTHER LIQUIDS, to be as follows:-
Our invention consists of various improvements in lamps for burning gasoline,
albo carbon, paraffin or other liquids.
For the purpose of enabling the supply of oil or liquid to the lamp burner to be
shut off when required and at the same time to allow the liquid which is in the
upper part of the wick to be consumed we divide the wick horizontally into two
portions, one of which and preferably the lower, can be moved up and down by
means of a handle or button outside the lamp so as to be brought into or out of
contact with the other portion. The lower portion is supplied with the oil or
liquid in any ordinary way and when this portion is in contact with the upper
portion the oil rises to the burner; when on the other hand the two portions are
not in contact the flow of oil to the upper portion ceases and the flame if burning
soon goes out. We prefer to make the wick of asbestos.
In order to increase the draught or current of air to the burner we prolong the
ordinary air tube of the lamp down the lamp support or holder to the bottom
thereof or to such distance as may be thought sufficient. We also divide the air
current by constructing an annular or other channel outside the wick tube and
causing a portion of the air to pass up the ordinary air tube to the burner and the
remainder to pass up this outside channel so as to impinge upon the outside of the
flame. We employ a thin annular disc of mica metal or other suitable material
resting on pins or projections on the sleeve or franic a little above the level of the
burner for the purpose of directing the air from the outside channel to the flame.
In order to regulate the flame we make the sleeve or frame which carries the
gallery and the chimney support with an incline at bottom or with an inclined
slot or groove to ride on a pin in the side of the lamp so that by turning the
sleeve or frame round on the pin it is raised or lowered together with the globe
and chimney and the distance of the bottom of the chimney from the burneṛ
thereby regulated or adjusted as required.

page_text: If the lamps are intended for liquids which explode or take fire at a low
temperature we adopt means by which when it is required to extinguish the lamp
the wick can be readily lowered into the liquid or a considerable distance below
the top of the wick tube; we thus avoid the risk of those accidents which are
caused by persons blowing down the chinney when they are unable to entirely
extinguish the flame by the ordinary means. For this purpose we connect the
wick tube to a vertical rod. This rod has connected to it a lever which in its turn
is connected to a horizontal rod extending to the outside of the lamp and fitted
with a knob or device for turning it. When it is desired to extinguish the lamp
the horizontal rod is turned and this through the lever causes the vertical rod and
wick tube to descend with the wick within an outer tube. We make the upper
part of the wick tube in the form of spring clamps or jaws which expand a little
when above the outer tube; this allows of a new wick being inserted from the top
of the tube instead of from the bottom as is usual.
For the purpose of allowing oil or liquid to be supplied to the reservoir without
unscrewing the upper part of the lamp we construct at the side of the wick tube
an oil supply tube which extends down into the reservoir while its upper part is
provided with a lid or cover which can be opened on a hinge or otherwise.
Dated thig 15th day of January 1881
We ALFRED DAVID TURNER of 34 Rippoth Road, Old Ford, in the County of
Middlesex, Engineer, and WILLIAM FLATAU of Lusan House, Highbury Quadrant,
in the same County, Gentleman do hereby declare the nature of our invention for
"IMPROVEMENTS IN LAMPS FOR BURNING GASOLINE, ALBO CARBON, PARAFFIN OR
OTHER LIQUIDS" and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
Our invention consists of various improvements in lamps for burning gasoline,
albo carbon, paraffin or other liquids.
For the purpose of enabling the supply of oil or liquid to the lamp burner to be
shut off when required and at the same time to allow the liquid which is in the
upper part of the wick to be consumed, we divide the wick horizontally into two
portions, one of which and preferably the lower can be moved up and down by
means of a handle or button outside the lamp so as to be brought into or out of
contact with the other portion. The lower portion is supplied with the oil or liquid
in any ordinary way, and when this portion is in contact with the upper portion
the oil rises to the burner, when on the other hand the two portions are not in
contact the flow of oil to the upper portion ceases and the flame if burning soon
goes out. We prefer to make the upper portion of the wick of asbestos. This
part of our invention in its application to a circular wick is illustrated in Figures 1,
2 and 3 of the annexed drawings, Figure 1 being a vertical section, Figure 2 an
elevation, partly sectional, at right angles to Figure 1 and Figure 3 a horizontal
section. a and b are respectively the upper and lower portions of the wick; the

page_text: upper portion a is held between the outer and inner tubes c, d of the lamp, while
the lower portion b is held between the tube d and a tube or slide c.
The upper
part of the tubes c and constitutes the burner. The lower portion b can be
moved up or down so as to be in contact or out of contact with the upper portion a
as required, by means of a finger piece or button foutside the lamp; "this button is
on the end of a rod g which turns in a tube or sleeve and has a crank & at its
inner end; the crank enters a slot in a piece so that when the piece f is turned
it acts upon the piece, moving it up or down as required together with a rod Z
which it carries; this rod passes through a slot m in the tube & and is connected
to the sliding tube c. j is the oil supply tube. The improvement is equally
applicable to flat wicks and to lamps with 2 or more wicks in which latter case
the movable parts of the several wicks may be moved up and down simultaneously
by mechanism connected with a single finger piece or button as will be readily
understood.
In order to increase the draught or current of air to the burner wo prolong the
ordinary air tube of the lamp down the lamp support or holder to the bottom
thereof or to such distance as may be thought sufficient. We also divide the air
current by constructing an annular or other channel outside the wick tube and
causing a portion of the air to pass up the ordinary air tube to the burner and the
remainder to pass up this outside channel so as to impinge upon the outside of the
flame. This part of our invention is illustrated by the same figures; n is the
ordinary air tube prolonged into the lamp support; o is the outside channel. Wo
employ a thin annular disc of metal, mica or other suitable material as represented
at p, Figure 1, carried by pins q or projections on the lamp a little above the level
of the burner for the purpose of directing the air to the flame; the height of the
disc can be adjusted by raising or lowering the pins q in the guides r.
In order to regulate the flame we make the sleeve or frame which carries the
gallery and the chimney support with an incline at bottom (or with an inclined
slot or groove) to ride on a pin in the side of the lamp, so that by turning the
sleeve or frame round on the pin it is raised or lowered together with the globe
and chimney and the distance of the bottom of the chimney from the burner
thereby regulated or adjusted as required. This improvement is illustrated in
Figure 1, s, s being an incline at the bottom of the gallery t, and u being the pin
in the side of the lamp. If the lamps are intended for liquids which explode or
take fire at a low temperature, we adopt means by which when it is required to
extinguish the lamp the wick can be readily lowered into the liquid or a con-
siderable distance below the normal position of the top of the wick holder; we
thus avoid the risk of those accidents which are caused by persons blowing down
the chimney when they are unable to entirely extinguish the flame by the ordinary
ineans. This part of our invention is illustrated in Figures 4, 5 and 6, Figure 4
being a vertical section, Figure 5 an elevation partly sectional at right angles to
Figure 4 and Figure 6 a view as seen from below. We connect the wick holder a
to one end of a vertical rod b. This rod has connected to its other end a lever c
which in its turn is connected to a horizontal rod d extending to the outside of
the lamp and fitted with a finger piece or device e for turning it. When it is
desired to extinguish the lamp the horizontal rod d is turned and this through the
lever causes the vertical rod b and wick holder « to descend with the wiek within
an outer tube f. We make the upper part of the wick holder in the form of spring
clamps or jaws g, g which expand a little when above the outer tube f; this allows
of a new wick being inserted from the top of the holder a instead of from the
bottom as is usual.
For the purpose of allowing oil or liquid to be supplied to the reservoir without
unscrewing the upper part of the lamp, we construct at the side of the wick tubo
an oil supply tube which extends down into the reservoir while its upper part is
provided with a lid or cover which can be opened on a hinge or otherwise. This
oil supply tube is represented at h in Figures + and 6, its upper part which is
deflected outwards for convenience of access is fitted with a hinged lid i.

page_text: Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed, we declare that what
we claim is:-
1. The employment in lamps of wicks divided horizontally into two portions,
one of which can be moved up and down by means of a device outside the lamp
so as to be put into or out of contact with the other portion, substantially as and
for the purpose herein before described and represented in Figures 1, 2 and 3.
2. Constructing lamps for burning gasoline or other liquids with an air channel
outside the wick tube in combination with an air tube within the wick substan-
tially as and for the purpose hereinbefore described and represented in Figures 1,
2 and 3.
3. The employment in lamps of an annular disc for directing the air to the
Blame substantially as hereinbefore described and represented in Figures 1 and 3.
4. Making the sleeve or frame which carries the gallery and chimney support of
lamps, so that its height can be adjusted as herein before described and represented
in Figure 1.
5. Constructing lamps for burning gasoline or other liquids so that the wick can
be readily lowered into the liquid or a considerable distance below the normal
position of the top of the wick holder substantially as bereinbefore described and
represented in Figures 4, 5 and 6.
6. Making the upper part of the wick holder of lamps in the form of spring
clamps or jaws which expand when above an outer tube as and for the purpose
heroin before described and represented in Figures 4 and 5.
