Improved Travelling Lamp suitable for Advertising Purposes.
I, OSMOND FERGUSSON, Anylitical Chemist, of 190 Eglinton Road, Woolwich
Kent, do hereby declare the nature of this invention to be as follows:-
My invention consists in forming a small lamp suitable for travelling purposes
in a very cheap manner, so that it can be inade and sold with a profit of one penny.
We stamp a thin piece of metal such as tin in a form so that a round top portion
is concave, and this acts as a reflector. Below this a straight portion is formed for
a given distance and this terminates at the bottom by being bent forwards at right
angles and this forward projecting part is cut or split in such a manner as will
permit the leaves of a book or pamphlet to be tightly inserted in the same.
I now form two concave portions and lap the joints one over the other so as to
This small con-
form a small container, the neck of which is open at the top.
tainer or reservoir is soldered to the vertical portion before referred to in such a
manner that the neck of the same in which the wick of the lamp is placed is about
level with the bottom of the reflector or thereabouts. The bulb or container is
filled with a mixture of melted wax and oil which is solid below a temperature
65° or thereabouts.
A small wick the depth of the container is first dipped in wax and allowed
to cool so as to make it stiff; it is then inserted in the container while its
contents are in a liquid state. The formation of the neck or burner to the con-

ourselves to the exact nature of the substances to burn, which are placed in the
container or lamp, but they will be of such a nature as to be solid in form below a
temperature of 65 degrees F. and to melt between 65 or 70 degrees F. or there-
abouts. The bulb or container is one inch in diameter or thereabouts, and by means
of our lamp as before described which we can manufacture and sell at a profit for
A.
one penny we can obtain a light of about one candle power for about one hour.
small portion of the metal above the reflector can be cut and turned out in the
manner of a hook.
It will have been seen by the explanation herein given that the metal portions
of my improved lamp are of three pieces only wz.:-two pieces for this bulb or
container (or lamp proper), and one piece for the combined stand and reflector.
may make my improved travelling lamp of any thin suitable sheet metal, and
advertisements inay be stamped or printed either upon the reflector the bulbous
container or on the forward projecting portion which clips the lamp upon the leaves
of the book. It is intended to use this lamp as before mentioned by affixing it
temporarily to the top of the leaves of a book or pamphlet which a person may be
reading. In lighting the lamp it is often necessary for a short time to place a
lighted match underneath the bulbous container so as to melt its contents before
lighting the wick.

Improved Travelling Lamp suitable for Advertising Purposes.
I, OSMOND FERGUSSON 190 Eglinton Road Woolwich Merchant, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement :-
Our invention relates to an improved travelling lamp for use when reading, to
be attached to a book or other article, and which can be used for advertising
purposes.
A piece of thin metal, such as tin, is stamped with a circular top, slightly
concave, acting as a reflector for the lamp, and an enlarged piece at the lower end
connected to the reflector by a narrow strip. A tongue is stamped out of the
centre of this enlarged part, by means of which the lamp is attached to the book,
the tongue serving to hold the cover or leaves to the enlarged part, the connecting
strip being bent to a suitable angle, so that the upper part shall be above the
book and reflect the light down onto it. A projecting piece at the top of the
reflector is turned over, forming a hook for use if the lamp is required to be
suspended. This piece serves as a holder for the lamp which is formed out of two
pieces of similar metal, concave, with a rimm round each, one having a much larger
rim than the other. At one part these rims project further out and are slightly
recessed, so that when the two pieces are placed together; the larger rim is turned
over the smaller, forming a small container with a neck at top, projecting outwards
a short distance and open. This container is filled with a suitable substance, such
as a mixture of wax and oil which will melt at a low temperature. This is put in
when liquid and a small wick first dipped in wax and allowed to cool, is inserted
through the neck, reaching to the bottom of the container, the contents becoming
solid when cool, thus preventing any escaping when carried about. The neck is so
formed that the opening is wedge shaped at each side of the wick, for the purpose of
allowing air to penetrate freely to the interior of the container when the oil or wax
is being consumed. This container is soldered or otherwise fixed to the holder in
such a position that the flame from the wick is at the lower part of the reflector.
In lighting the lamp, the match should first be used to heat the container slightly
and melt some of the contents, the heat from the wick being sufficient to keep the
wax melted after lighting. According to another arrangement, instead of soldering
the lamp to the holder, the holder is stamped with an arm extending on each side a
little below the reflector, and a tongue a short distance below the arms.
tongue is bent at right angles, and the arms are turned partly round, and their
ends bent to receive the flange of the lamp, which is slipped between them and
rests on the projecting tongue. Advertisements may be stamped or otherwise
fixed on the edges of the reflector, the front of the lamp or container, or any con-
venient part of the holder.
Referring to the accompanying sheet of drawings,

The
Fig. 1 is a front and Fig. 2 a side elevation of the arrangement first described.
Fig. 3 a front view of the piece forming the holder before the arms are bent and
the lamp inserted.
Figs. 4 and 5 front and side elevations of lamp complete, and..
Fig. 6 a plan of the lamp or container, Figs. 3, 4 and 5 showing the second
arrangement.
1 is the upper circular part forming the reflector, being provided with the hook 2
for use if the lamp is desired to be suspended, 3 is the lower piece having tongue 4,
and connected to the reflector by the narrow part 5 which is preferably slightly
channelled, as shown. 6 is the lamp or container shown in Figs. 1 and 2 fixed to
the holder, having a neck 7 and formed as shown in plan Fig. 6 with wedge
shaped opening on each side of the wick for the purpose herein before described.

page_text: Referring to Figs. 3, 4 and 5, 8 are the arms bent so as to prevent the lamp 6
from falling out after being inserted, and 9 is the tongue on which the lamp rests.
The holder is bent just above the lower part 3 when attached to the book.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
(1) A portable travelling lamp consisting of a holder stamped or otherwise
formed from a single piece of metal & comprising a reflector and means for
attaching to a book or suspending in any suitable manner, and a lamp or container
attached to holder immediately below the reflector substantially as described.
(2) A holder for travelling lamps formed from a single piece of metal, comprising
a reflector 1, a book clip 3, 4, & connecting piece 5, to which the lamp 6 is
attached.
(3) A travelling lamp comprising a holder of suitable construction, and a lamp
or container 6 formed of two pieces of thin metal, part of each being concave, with
a rim, one rim being larger than the other and bent round the second one, forming a
hollow case with a neck of the form shown in Fig. 6, substantially as described
and for the purposes specified.
