I, CHARLES HORACE WALL REMMETT of 37 Tarn Street, Newington
Causeway, London S.E. late of 114 New Church Road, Camberwell, London S.E.,
Engineer, 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 :-
My invention relates to an improved oil lamp, and has for its purposes to prevent
explosions arising from the wick being turned down into the oil reservoir as has
been possible, in the form of lamps hitherto made and used, and to prevent fire and
other accidents arising from the upsetting or dropping of the lamp.
The principle of my invention consists in providing the wick tube separate and
distinct from the oil reservoir, and to which the oil is fed by a curved tube or
conduit, extending from the bottom of the reservoir to the lower end of the wick
tube, at which point the said conduit is provided with a valve or perforated nozzle,
through which the oil percolates into the wick tube, such perforation, while
sufficiently large to pass the quantity of oil necessary to support combustion, would
not pass sufficient to permit a confiagration should the lamp be dropped or upset
and the glass broken. The top or cover of the reservoir is provided with a screw
cap, having a central hole of sufficient size to admit air into the reservoir to
replace the oil as consumed, and for ordinary hand lamps, or such as are intended
to be carried about from place to place, I prefer to construct the said reservoir of
pyramidical formation, which provides, that should the said lamp be knocked over
while standing upon a flat surface the oil in the reservoir would flow from the
conduit to, and close the air inlet in, the reservoir cover, thus creating a partial
vacuum in the reservoir, and so extinguish the lamp. The same would occur if the
lamp be dropped upon the floor or ground as in most cases this would topple over
upon its side, or failing this, the sudden impact with the floor or ground would
cause a jar that alone would be sufficient to extinguish the flame.

page_text: In order that my invention may be fully understood I have hereunto appended a
sheet of drawings, of which
Fig. is a side elevation of a hand lamp substantially as I prefer to construct
them for domestic purposes or for the use of warehousemen, and cellarman, or for
use in a ships hold or forecastle.
Fig. 2 is an elevation of a lamp as I prefer to construct them for hanging upon
a wall or other vertical surface.
Fig. 3 is a lamp similar to Fig. 1 but having two or more burners.
Fig. 4 is an enlarged section upon the line A B Fig. 1, Fig. 5 being a further
enlarged section of the valve or fixed nozzle shown at Fig. 4.
For the purposes of my invention I construct of any kind of metal suitable for
the purposes, a reservoir A, which may be of any shape according to whether the
lamp is to be used as a hand lamp or for suspension, but for the former purpose
I prefer to construct this of pyramidical form as at Fig. 1, and provided with a
suitable hand hold B3, and screw cap C, (the latter covering a hole through which
the said reservoir may be charged) and in which a small perforation or hole (not
shewn is provided, for the purpose of admitting the necessary air to the reservoir.
The botton D of the oil chamber proper, I prefer shall be a suitable distance above
the lower end of A, as shewn in Fig. 1, and upon and level with the bottom of A
I solder or otherwise connect thereto, an extension piece or prolongation E, upon
which I solder or otherwise mount the lower end of a wick tube F, with one of its
flat sides facing A, and upon the upper end of FI solder, screw, or otherwise
mount any kind of ordinary burner G, provided with a flame cone H, hinged or
otherwise connerted thereto, and a chimney gallery 3, in the usual way.
The oil is fed from the reservoir A to the wick a in the wick-tube F, by a tube
or conduit K, one end of which enters the bottom D), at any convenient part, but
preferably, as far as possible from the with the F, from which point the said
conduit is curved first in a downward and then in an upward direction, and
extends as far as the wick tube F, and has subdered or otherwise connected
thereto a tap or cock, or for preference a valve or nozzle L, (shewn enlarged at
Fig in which a through passage, is provided, the said nozzle being then
soldered or otherwise connected to a boss surrounding an inlet to the wick tube F,
as shewn in Fig. 4.
The passage in the nozzle L has, by preference, two diameters, the size of the
smaller of which being such as may be found most suitable for supplying oil from
the reservoir A to the wick a, in sufficient quantity to support combustion, the
wick a being at all times of such size in cross section as to fully occupy the tube F,
so that the oil fed thereto through the conduit K may, by saturating the same, bu
conveyed to the burner G by capillary attraction alone, and by reason of the
burner G being level with, or slightly above, the supply cover C, of the reservoir A,
flooding of the tube F, or the overflowing of the burner is simply impossible, and
by reason of the limited size of the passage in the nozzle L, the supply of oil
could not be in excess of this should the lamp be tilted or upset, and since the
wick a is not in contact with the oil in the reservoir A, it is not possible for
accidents to occur as hitherto, by the lighted wick being turned down into the said
oil, thus permitting the use of oils of a low flashing point with greater safety than
hitherto,
I may find it convenient to construct hand lamps having two such conduits K
and wick tubes F and burners, as shewn at Fig. 3, in which case these would be
arranged for connection with the bottom D at opposite sides, bending and passing
each other below it as shewn. Or where such lamps are intended for suspension,
such as in ships holds or forecastles, cellars or other places, 1 may provide four
such conduits, wick tubes, and burners, in which case the third and fourth
conduits K, (not shown) would leave the bottom D at opposite sides to each other,
and at right angles to those shewn in Fig. 3, and the reservoir A may be provided
with means, such as a chain M, for suspending the same when required.
In lamps that are intended for fixing upon walls or other vertical surfaces,

page_text: I prefer to construct these substantially as at Fig. 2, the reservoir A of which may
be of any size, shape, or configuration having one flat side A', provided with any
suitable means for suspending the same, which may be that of lugs such as d,
engaging with suitable slots in the said wall or other vertical surface.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:
1st. In oil lamps for hand, fixing, or suspension purposes, the herein discribed
method of, and means for, arranging the wick tube separate from, and with the
wick not in connection with, the oil in the reservoir, substantially as and for the
purposes herein set forth and shewn.
2nd. In an oil hand lamp, the combination of a reservoir A, with handle B,
perforated screw-cap C, and bottom D, from which the oil is fed, by one or more
conduits such as K to the wick tube or tubes F, mounted upon an extension or
extensions E, connected to A, and carrying any suitable form of burner or burners
such as G, the said feed of oil being governed by a tap or cock, or a nozzle such
as L, in the, or each of the conduits, and cach provided with a passage such as b
substantially as and for the purposes herein described and shewn.
3rd. In an oil suspension lamp, the combination of a reservoir such as A, with
perforated cap C, and bottom D, from which the oil is fed by one or more conduits
such as K, to the wick tube or tubes F, mounted upon an extension or extensions E,
and carrying any suitable form of burner or burners such as G, the said feed of
oil being governed by a tap or cock, or nozzle such as L, in the, or each of the
conduits K, with means such as d for suspending or fixing the said lamp upon a
wall or other vertical surface, such as A', substantially as described and shewn.
4th. In an oil-lamp of the type set forth in the preceding claims, having two or
more burners such as G, and wick tube F, cach supplied by a conduit K governed
by a tap or cock, or nozzle such as L, with means such as M, for suspending the
said lamp where required, substantially as herein described and shewn.
Dated this 11th day of July 1896.
