PROVISIONAL
SPECIFICATION.
Improvements in and relating to Paraffin or Oil Lamps.
ALEXANDER ECKFORD 14 Great Junction Street Leith Cashier do hereby declare
the nature of this invention to be as follows:-
The object of this invention is to improve the construction and arrangement of
Paraffin or Oil Lamps for the prevention of vaporising the oil in fount or reservoir
and for the prevention of flame communicating from burner to the fount or reservoir
and thereby making the Lamp absolutely safe from explosion.
First, Single Wick Lamps, to the burner I solder a close fitting wick tube which is
carried to the bottom of fount or reservoir and carried beyond the bottom of fount if
desired attached to the bottom of wick tube is a cross or angled tube preferably made
flat, and of such a small size as to prevent flame passing through it, this wick tube
passes through an annular space in centre of fount which is made in the form of a tube
passing through centre of fount vertically and thereby allowing an air space right
round wick tube and thereby inducing a draft of air which keeps the oil in fount from
vaporising as by this means the fount cannot get overheated, when the wick tube is
projected say three inches or thereby below the fount, the oil contained therein forms
a seat and completely prevents any gas generated in wick tube passing to the fount, or
reservoir.
In the Duplex Lamp I employ the same arrangement with 2 wick tubes instead
of 1, and this invention can be applied to Lamps with round burners by the same
method, and securing the complete isolation of the wick from the body of oil in fount
or reservoir.

Improvements in and relating to Paraffin or Oil Lamps.
ALEXANDER ECKFORD 14 Great Junction Street Leith Cashier 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:-
This invention relates to improvements by means of which the vapourising of the
oil in Paraffin or Oil Lamps is prevented keeping the Lamp from getting overheated,
the prevention of Flame communicating from burner to fount or reservoir, and thereby
making the Lamp absolutely safe from explosion.
To attain this object, I solder a close fitting wick tube to burner which is carried to
the bottom of fount or reservoir and carried beyond the bottom of fount or reservoir
if desired. Attached to the bottom of wick tube is a cross or angled tube preferably
made flat and of such a small size as to prevent flame passing through it. This wick
tube passes through an annular space in centre of fount, which is made in the form of
a tube passing through centre of fount or reservoir vertically, and thereby allowing an
air space right round wick tube, and inducing a draft of air, which keeps the oil from
vapourising, as by this means the fount or reservoir cannot get overheated, when the
wick tube is projected say three inches or thereby below the fount or reservoir the oil
contained therein forms a seal and completely prevents any gas generated in wick
tube, passing to the fount or reservoir.

page_text: In the Duplex Burner Lamp I employ the same arrangement, with two wick tubes
instead of one, and two angled tubes to convey the oil from fount or reservoir to wick
tubes.
In the Round Burner Lamp I use a close fitting round wick tube with two angled
tubes in the same manner as the Duplex Lamp.
The Duplex Burner may be pierced through the centre for the purpose of allowing
an additional and internal supply or draft of air, thereby assisting the combustion;
and to cause a greater draft I attach sheet metal by solder to the sides of wick
tubes, thereby forming a square hole or aperture from the burner to the bottom
of wick tubes.
By the foregoing means I secure the complete isolation of the wick or wicks from
the body of oil in fount or reservoir.
In the accompanying drawing is shown the Duplex Burner Lamp.
A burner. B. B. wick tubes leading to & projecting beyond bottom of fount.
C. C. angled tubes conveying oil from fount or reservoir to wick tubes. D. D. fount
or reservoir. E' E' annular air space. E2 air space between wick tubes. F per-
forated collar attached to fount or reservoir.
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 I am aware that it has
been proposed to construct oil lamps having air spaces round and between the wick
tubes for the purpose of keeping the reservoir cool and that I lay no claim at large
to such an arrangement, but what I claim is :-
1st. The employment of close wick tube or tubes so that the wick or wicks fit
tight into wick tube or tubes.
2nd. The sealing arrangement of wick tube or tubes in conjunction with the angled
tube or tubes.
3rd. The adoption of the small bore in the flat angled tube or tubes conveying
oil from fount to wick tubes.
4th. Adapting the angled tubes and wick tube so as to form a seal applicable to
round wick burner Lamps.
Dated this Twenty-fourth day of January, Eighteen hundred and ninety.
