An Improved Night Light for Domestic Purposes.
Year: 1898

page_text: ARTHUR JAMES HAMMOND, 24, Hawke Street, Barrow in Furness, Engineer, do
hereby declare the nature of this invention to be as follows:-
An ordinary lamp glass vessel to contain parrafin oil, the neck of which is
covered with a brass cap.
In the centre of the cap there is a ¼ inch hole to admit a tube (made of brass or
any other metal) to pass through.
The tube is fixed in the centre of the cap so as to hold the wick to pass through
to the oil. It is fixed in a perpendicular position and in length according to the
size of glass vessel used. It has no side screw arrangement but on the top of
the tube is inserted a nipple, having a screw thread inside for the regulation of
the wick.
The advantage of the above, is, that it introduces a new burner which is absolutely
free from smoke or smell. It is a very cheap night light, and will burn 400 hours
at the cost of one penny.
It is a naked light.

An Improved Night Light for Domestic Purposes.
I, ARTHUR JAMES HAMMOND, of 24, Hawke Street, Barrow-in-Furness, 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:
This invention relates to the class of lamps which are used as night lights, that
is to say, to lamps which are required to give but little light, and are therefore
fitted with small wicks. In lamps of this class, as heretofore or usually con-
structed, the smallness of the wicks has had to be limited to such size as has made
it practicablé to raise them by means of star wheels such as are commonly employed
for raising wicks of larger size, and consequently the lamps have given too much
light and have been therefore wasteful.
Now, this invention has for its object to provide means of a simple character
whereby a wick of very small diameter may be very conveniently fed through the
wick tube as required.
According to this invention, the burner of the lamp is fitted with a wick tube
[Price 8d.]

page_text: of the usual construction, except that the tube is made of a diameter which is con-
siderably larger than is required simply for the passage of the wick therethrough.
Within the upper part of the tube is fitted a nozzle which has a screw-threaded
hole formed down through it of a diameter which will allow the wick to be easily
screwed therethrough. When it is desired to raise the wick (which is usually only
when the lamp is being trimmed), the nozzle is removed from the tube, the wick
gripped between the finger and thumb immediately below the lower end of the
nozzle and the nozzle and wick twisted or screwed, the one in relation to the other,
until the wick is screwed sufficiently through the nozzle to project for the required
distance thereabove.
In order that the invention may be clearly understood, I will now proceed to
describe the same by the aid of the accompanying drawings of which Figure 1 is
a vertical section through the upper portion of a night light constructed acccording
to this invention, the globe being shewn by broken lines. Figure 2 is a plan of
the burner shewn by Figure 1. Figure 3 is a detached vertical section, to an
enlarged scale, of the nozzle; and Figure 4 is a similar view to Figure 3, but
shews, also, the upper portion of the wick tube.
The main portion of the burner A is of the usual construction, and is fitted to
the oil container or body B of the lamp in the usual or any convenient manner.
The wick tube is also similar to that usually employed, except that it is of a
larger internal diameter than is required merely for the passage of the wick b,
instead of being of the same diameter as is usual. Within the upper end of the
wick tube a, is removably fitted a nozzle c which has a screw-threaded hole d
formed down through it of a diameter which will allow the wick to be screwed
easily therethrough. The nozzle is formed with a flange or enlargement e around
its upper end which answers the double purpose of enabling the nozzle to be easily
withdrawn from the wick tube, and of preventing it from dropping down the tube.
The nozzle might, of course, be prevented from dropping down the tube by forming
the tube with a shoulder or flange for the lower end of the nozzle to rest upon.
is preferred however, to form the nozzle with a flange around its upper end for
convenience of manipulation. The nozzle should be somewhat loose or an easy fit
within the tube to allow of the ready escape of vapour.
It
When it is desired to raise the wick, the nozzle is, as already described, with-
drawn from the wick tube, the wick gripped between the finger and thumb
immediately below the lower end of the nozzle, and the nozzle and wick turned,
the one in relation to the other, until the wick has been advanced for the required
distance through the nozzle; after which the nozzle is, of course, replaced within
the tube. Holes f are formed through the top plate g of the burner for the passage
of air to the flame. The hole d through the nozzle is, preferably, formed bell-
mouthed at its lower end, as shewn, to assist in guiding the wick into the hole.
The lamp may be used without the glass or globe C if placed out of draught.
While it is much preferred to forni the nozzle with a screwed hole therethrough
to facilitate the adjustment of the wick, a nozzle with a plain hole therethrough may
be used and much of the advantage of the invention be still obtained, as the use
of such a nozzle also enables the wick to be readily put in place, and a very small
wick which it would not be practicable to raise by means of star wheels may be
adjusted through such nozzle by removing the nozzle from the wick tube and then
holding the wick below such nozzle and twisting it therethrough.
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. A night light of the character above defined, having a nozzle which is remov-
ably fitted to the wick tube and has an opening formed therethrough for the
passage of the wick, substantially as described.
2. A night light of the character above defined, the burner of which is provided

page_text: with a nozzle having a screw-threaded opening formed therethrough for the passage
of the wick, such nozzle being capable of being moved, in relation to the burner,
to allow the wick to be advanced therethrough, substantially as described.
3. A night light of the character above defined having a nozzle which is remov
ably fitted to the wick tube and has a screw-threaded opening formed therethrough
for the passage of the wick, substantially as described, for the purpose set forth.
4. A night light of the character above defined, having an internally screw-
threaded nozzle for use in adjusting the wick, substantially as described and
shewn by the drawings herewith.
