Improvements in and relating to Lamps.
I, JOHN LEWIS, of 169, Seven Sisters' Road, Holloway, in the County of London,
Oil and Colourman, do hereby declare the nature of this invention to be as
follows:
In table lamps, and lamps intended more especially for use as night lights, for
burning in food warmers, fairy lamps, and the like, it is customary to employ a
metallic wick tube. This tube is found to be objectionable on account of its
liability to corrosion, and likewise owing to its becoming heated and causing a
vaporization of the oil and consequently a more or less unpleasant odour, and for
other reasons. My present invention has for its object to obviate the above defects
and to effect the improvements hereinafter indicated.
According to my said invention I provide a suitable metal cap carrying the
metal wick tube, and the wick raising and lowering device, which cap is adapted to
be connected with the mouth or aperture of the oil reservoir in any convenient or
well-known manner. The metal wick tube is arranged to extend to, or only for a
short distance beyond, the wick raising and lowering device, and over the projecting
extremity of such metallic wiek tube I fit loosely a short length of tube formed of
annealed or other suitable glass, which latter tube forms a continuation of the
metallic wick tube. This short length of glass tube is preferably formed with a
flange or bell-mouthed or flaring at its lower or that extremity which is adapted
to fit over the projecting portion of the metallic wick tube, and the glass tube or
piece is held in place by means of a second or supplementary cap having a suitable
hole or aperture through which the said glass tube or piece passes, which second
or supplementary cap is secured to the main cap by fitting the same over or upon a
socket, by means of a bayonet joint, or in any other manner, which will admit
of its being readily removed for cleansing purposes, or for the renewal of the
above mentioned glass tube or piece.
It will be readily understood that my improvements are applicable to lamps
When
adapted to receive either round, flat, or any other description of wicks.
applied to a large lamp, the above described short length of glass tube is preferably
so arranged as to act as an extinguisher should the lamp be accidentally overturned
or upset.

I, JOHN LEWIS, of 169, Seven Sisters' Road, Holloway, in the County of London,
Oil and Colourman, do hereby declare the nature of this invention and in what

in and by the following statement:-
In table lamps, and lamps intended more especially for use as night lights, for
burning in food warmers, fairy lamps, and the like, it is customary to employ a
metallic wick tube. This tube is found to be objectionable on account of its
liability to corrosion, and likewise owing to its becoming heated and causing a
vaporization of the oil and consequently a more or less unpleasant odour, and for
other reasons. My present invention has for its object to obviate the above defects
and to effect the improvements hereinafter indicated.
In the accompanying drawings,
Figure 1 shows in elevation and
Figure 2 in vertical central section, a lamp embodying my improvements.
According to my said invention I provide a suitable metal cap a carrying the
metal wick tube and the wick raising and lowering device c. The cap is
adapted to be connected with the mouth or aperture of the oil reservoir d in any
convenient or well-known manner. In the drawings the cap a is shown as being a
good fit over the mouth of the reservoir. The metal wick tube b is arranged to
extend to, or only for a short distance beyond, the wick raising and lowering
device, and over the projecting extremity of such metallic wick tube I fit loosely a
short length of tube e formed of annealed or other suitable glass, which tube e
forms a continuation of the metallic wick tube b. The glass tube is preferably
formed as shown with a flange or bell-mouth or flaring at its lower or that ex-
tremity which is adapted to fit over the projecting portion of the metallic wick
tube band such glass tube e is retained in place by means of a second or supple-
mentary cap having a suitable hole or aperture through which the said glass tube
passes. The said cap f is secured to the main cap a by fitting the same over or
upon a socket, or by means of a bayonet joint such as that indicated at g, or in any
other manner which will admit of its being readily removed for cleansing purposes,
or for the renewal of the above mentioned glass tube or piece c.
It will be readily understood that my improvements are applicable to lamps
adapted to receive either a round wick, such as that shown at h, or a flat one, or one
of any other suitable description. The above described short length of glass tube
acts as an extinguisher and it will so act should the lamp be accidentally overturned
or upset.
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 glass tube e substantially as set forth.
2. The supplementary cap f substantially as set forth.
3. In a lamp, the combination, with the nietallic wick tube, of a glass tube loosely
fitting over the end of the metallic tube, and a supplementary cap serving to retain
the glass tube in position substantially as set forth.
4. The glass tube loosely fitting over the end of the metallic wick tube and serving
as an extinguisher substantially as set forth.
5. The lamp constructed substantially as described and as illustrated in the
accompanying drawings.
