PROVISIONAL SPECIFICATION.
An Improved Lamp for Burning the Gas from Benzoline and other
Spirits.
I JOHN DAVID CURR of 4 Chapel Walks Manchester in the County of
Lancaster, Manufacturer, do hereby declare the nature of this invention to be as
follows:-
The object of this invention is to construct an economical and efficient hand
lamp for the purpose of burning the gas from benzoline and other spirits which
evolve inflammable gas.
I construct a can or vessel of a suitable size and form (preferably a truncated
cone) from tin plate or other suitable metal.
This can is provided with a handle of convenient form for carrying the same and
the top thereof is formed with a feed opening for filling the same which is closed
by a screw cap in which is a small perforation or aperture to admit air to the
interior of the vessel.
In the front part of the top (or that part furthest from the handle) I form another
opening in which is soldered a screwed socket into which I screw the wick tube or
tubes, of which there may be one or more.
The wick tube is a plain tube fixed in a direction sloping upwards and forwards
like the spout of a can or kettle, its inner end projecting a short distance into the
can, and its outer end formed with a screw. Upon this end I screw a small hollow
brass or other sphere or bulb which is perforated with five (or any other convenient
number of) small holes.
The cotton or other wick is passed down this tube, a portion thereof lying in the
bottom of the can and with its upper end about flush or nearly so with the mouth
of the wick tube or spout.
The hollow sphere or bulb forms a receptacle in which the gas is received or
collected and being ignited on issuing from the small holes therein burns with a
steady and brilliant light.

COMPLETE SPECIFICATION.
An Improved Lamp for Burning the Gas from Benzoline and other
Spirits.
JOHN DAVID CURR of 4 Chapel Walks Manchester in the County of
Lancaster Manufacturer do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following statement:-
The object of this invention is to construct an economical and efficient hand lamp
for the purpose of burning the gas from benzoline or other spirits which evolve
inflammable gas.
The nature of my said invention and the manner in which the same is to be
performed or carried into practical effect will be readily understood on reference to
the drawing hereunto annexed and the following explanation thereof. The drawing
represents a vertical section of one of my improved lamps drawn about the real
size.
I construct a can or vessel a of a suitable size and form (preferably a truncated
cone) from tin plate or other suitable metal.

page_text: This can is provided with a handle of convenient form for carrying the same
and the top thereof is formed with a separate feed opening for filling the same
which is closed by a screw cap c in which there may be a small perforation or
aperture to admit air to the interior of the vessel.
In the front part of the top al (or that part furthest from the handle) I form
another opening in which is soldered the wick tube d of which there may be one or
more.
The wick tube is a plain tube d fixed in a direction sloping upwards and forwards
like the spout of a can or kettle, its inner end projecting a short distance into the
can, and its outer end formed with a screw or plain as may be preferred. Upon
this end screw or otherwise fix a small hollow brass or other sphere or bulb e
which is perforated with five (or any other convenient number of) holes.
The cotton or other wick is passed down this tube, a portion thereof lying in
the bottom of the can and with its upper end about flush or nearly so with the
mouth of the wick tube or spout d.
The hollow sphere or bulb forms a receptacle in which the gas is received or
collected and being ignited on issuing from the small holes therein burns with a
steady and brilliant light.
In using this lamp the tube d or the bulb e must first be heated say in the flame
of a match or candle until the gas issues from the small holes in the bulb when it is
ignited and will burn with a steady flame so long as there is any benzoline or spirit
in the can.
The wick not being burned does not require to be renewed.
I am aware that Letters Patent No. 2360 of 1876 have been granted to John
Frederick Schnell for improvements in lamps for burning similar spirits but I do
not wish to claim as my invention anything described in the Specification of such
Letters Patent.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed declare that what I
claim is :-
The improved lamp for burning benzoline or other spirit consisting simply of a
can or vessel of suitable shape in the upper part of which is soldered or otherwise
permanently fixed in any convenient position or angle a wick tube or tubes provided
at the outer end with a perforated hollow sphere or bulb forming an accumulator
for the gas and also a burner, the can or vessel being also provided with a separate
filling opening fitted with a screw plug, substantially as hereinbefore described and
illustrated by the drawing annexed.
Dated this 22nd day of December 1890.
