Improvements in Oil Lamps.
I JOHN HERBERT LAPTHORN, Inventor, Patentec, and Manufacturer, 361A Oxford
Street, Chorlton-on-Medlock Manchester, do hereby declare the nature of this
invention to be as follows:-
These improvements consist in Oil Lamps formed & fitted with smooth, fluted,
grooved or other glass fonts or reservoirs with wire either plain, ornimental platted or
woven round the aforesaid fonts or reservoirs, and in addition India rubber bands or
rings interwoven with, or over and above the said wire.
It is clearly recognized and acknowledged by leading experts that oil attains a much
higher temperature in metal than in glass fonts, and owing to the danger arising
from the glass fonts breaking, metal fonts are at present inuch in use.
I therefore purpose to prevent, modefy, and lessen the danger, frequent explosions
and subsequent loss of life. And for this purpose I cover the glass font with copper,
brass, Iron or other wire, and in addition I place over or inter weave with the aforesaid
wire a rubber band or rubber bands or rings of suitable size shape & thickness to
prevent the glass font coming into contact with any hard substance when removed or
upset.
I would remark I am conversant with the fact that this method of useing wire has
been very successfully applied to mineral water containers, but not to Oil Lamps. I
purpose useing the safest and most Suitable Lamps, either with or without Self-acting
extinguishers, also making them as saleable & onnimental as possible. From the
above it will be readilly understood that the distinctive feature of my invention is
forming & fitting Oil Lamps with wire & rubber in the manner & for the purpose
set forth.

COMPLETE SPECIFICATION.
Improvements in Oil Lamps.
I JOHN HERBERT LAPTHORN, Inventor, Patentee, and Manufacturer 361A Oxford
Street, Chorlton-on-Medlock, Manchester, do hereby declare the nature of this
30 invention and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:
These improvements consist of oil lamps formed and fitted with smooth fluted
grooved or other glass fonts or reservoirs which I cover with brass, copper aluminium,

page_text: iron, or other suitable wire by platting, twisting, forming into meshes or any other
method of adaptation.
I would remark that I do not confine myself to any particular form of appling the
wire, but simply utilize the most practical one.
In one case I cover the font or reservoir of any ordinary glass lamp with netted wire.
I another case I cover the font of any ordinary glass lamp with netted wire and
emerge into a vessel of molten glass and then suitably finish, thus forming lamp
fonts with netted wire and glass externally parellel. Another method I adopt is to
form a cage or case of netted wire of suitable shape & blow therein molten glass
and thus form a font as described above by a different process.
In order that my invention may be more readilly understood I nave appended the
accompanying drawings which I now proceed to describe :-
Fig. 1 represents a complete oil lamp with glass font or reservoir and with my
additional improvements applied thereto; A netted wire B and C metal perforated
bands or rings to receive the netted wire A.
Fig. 2. illust rates a netted wire cage or case into which I blow the liquid or molten
glass, thus forming a font or reservoir with wire and glass externally parellel to which
I affix a suitable stand and burner.
Fig. 3. shows a complete lamp the font of which I make as described in Fig. 1 and
in addition I emerge into molten glass by which process the wire meshes are filled
and a lamp completed with wire and glass of equal surface.
To preserve the strength & colour of the wire from the effects of the heat I cover
it with magnesium carbide or other suitable solution.
Having now particularly described and ascertained the nature of my
invention and in what manner the same is to be performed, I declare that what I
claim is:
Forming and fitting the glass fonts or reservoirs of oil lamps with netted or other
wire substantially described hereinbefore and for the purpose set forth.
Dated this 12th day of August 1897.
