Improvements in Side Reflecting Lamps, Specially Applicable for
Illuminating Shop Windows and Show Cases and for Advertising
Purposes.
I, CHARLES GIBBONS of 55 Thurston Road, Loampit Vale, Lewisham, in the
County of Kent, Zineworker, do hereby declare the nature of this invention to be
as follows:-
My invention for improvements in side reflecting lamps specially applicable for
illuminating shop windows and show cases and for advertising purposes has for object
to construct a side reflecting lamp which can readily be lighted, which shall increase
the effect of the light and which shall also be effective as an advertising medium.
In a lamp constructed according to my invention, the flame which may be flat or
round, is enclosed in a hollow frame of conical or regular pyramidical form having its
axis when in position approximately horizontal. The frame is lined with enamelled
iron or other suitable substance so that its inner conical surface forms a reflector so as
to increase the effect of the light; and the base is formed of clear glass plate fixed in
a frame hinged to the conical part and forming a door secured by a latch in the
ordinary manner.
The reflecting surface instead of being truly conical or pyramidical is terminated
towards the apex by a small convex reflecting disc. Immediately over the flame
which is in the axis of the reflecting surface is an orifice communicating by means of
a pipe protected by a cowl with the atmosphere and at the highest part of the cone or
pyramid and at or near its base are openings or perforations also communicating with
the atmosphere. These openings serve for the exit of the products of combustion of
the flame and of the heated air. The cowl consists of a hollow truncated cone
mounted on the end of the pipe and surmounted by a hollow cone, there being
openings between the pipe and truncated cone and also between the cone and truncated
cone. At preferably the lowest part of the cone or pyramid and at or near its base
is an orifice or hole protected by a wind guard and serving for the entrance of air to
sustain the flame and also to ignite the lamp without opening the door. The angle of
the cone or pyramid may be arranged to give any desired range to the field of
illumination.

page_text: When desired to use the lamp also for advertising purposes, a portion of the
enamelled iron or other reflecting substance is replaced by enamelled glass having the
required advertisement on its back where the frame is removed or cut away, the said
back being preferably protected by clear glass so as to preserve it from injury. The
advertisement can thus be painted on the enamel instead of being burnt in. This
enamelled glass forms preferably the lower half of the cone or pyramid; or the
reflecting surface may be formed entirely of enamelled glass having a portion of its
back protected by the metal frame and another portion containing the advertisement
by clear glass. When of pyramidical form the reflecting surface may be formed of
separate plates jointed together in any suitable manner, as may also the clear glass
protecting it.

Illuminating Shop Windows and Show Cases and for Advertising
Purposes.
I CHARLES GIBBONS of 55 Thurston Road, Loampit Vale, Lewisham, in the County
of Kent, Zineworker, 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:—
My invention for improvements in side reflecting lamps specially applicable for
illuminating shop windows and show cases and for advertising purposes, has for object
to construct a side reflecting lamp which can readily be lighted, which shall increase
the effect of the light, and which shall also be effective as an advertising medium.
In a lamp constructed according to my invention, the flame which may be flat or
round, is enclosed in a hollow frame of conical or pyramidical form having its axis
when in position approximately horizontal. The frame is lined with enamelled iron or
other suitable substance so that its inner surface forms a reflector so as to increase the
effect of the light; and the base is formed of clear glass plate fixed in a frame hinged
to the conical or pyramidical part and forming a door secured by a latch in the
ordinary manner.
The reflecting surface instead of being truly conical or pyramidical is terminated
towards the apex by a small concave deflecting disc-Immediately over the flame
which is in the axis of the reflecting surface is an orifice communicating by means of
a pipe protected by a cowl with the atmosphere, and at the highest part of the cone
or pyramid and at or near its base are openings or perforations also communicating
with the atmosphere. These openings serve for the exit of the products of combustion
of the flame and of the heated air. The cowl consists of a hollow truncated cone
mounted on the end of the pipe and surmounted by a hollow cone, there being per-
forations in the end of the pipe under the truncated cone and an opening or outlet
between the cone and truncated cone. At preferably the lowest part of the cone or
pyramid and at or near its base is an orifice or hole protected by a wind guard and
serving for the entrance of air to sustain the flame and also to ignite the lamp
without opening the door. The angle of the cone or pyramid may be arranged to give
any desired range to the field of illumination. When desired to use the lamp also
for advertising purposes, a portion of the enamelled iron or other reflecting substance
is replaced by enamelled glass having the required advertisement on its back where
the frame is removed or cut away, the said back being preferably protected by clear
glass so as to preserve it from injury. The advertisement can thus be painted on the
enamel instead of being burnt in. This enamelled glass forms preferably the lower
half of the cone or pyramid; or, the reflecting surface may be formed entirely of
enamelled glass having a portion of its back protected by the metal frame and another
portion containing the advertisement by clear glass. When of pyramidical form the
reflecting surface may be formed of separate plates jointed together in any suitable
manner, as may also the clear glass protecting it.
In the accompanying sheet of drawings:-
Fig. 1 is a front elevation of a side reflecting lamp constructed according to this
invention and,
hi is a sectional alevation and

page_text: The flame a which may be flat or round is enclosed in a frame of pyramidical
form having its axis when in position approximately horizontal. The upper part
of the frame is lined with enamelled iron c or other suitable substance, the
lower part being lined with segments of enamelled glass d having the required
advertisements on their backs, the said backs being protected by corresponding
segments of clear glass e so as to preserve them from injury. The advertisements
can thus be painted on the enamel instead of being burnt in. The base is formed
of clear glass plate f fixed in a frame g binged to the foundation ring b, of the
frame b and forming a door secured by a latch in the ordinary manner.
The foundation ring b, is composed of a hollow rectangular tube bent round to
form a rigid base for the frame and also to facilitate the ventilation of the
lamp as hereinafter described.
The reflecting surface instead of being truly pyramidical is terminated towards
the apex by a small convex reflecting disc 7.
Immediately over the flame a is an orifice communicating with the atmosphere
by means of a pipe protected by a cowl composed of the hollow truncated
cone and surmounted by the hollow cone m there being perforations m, in the
pipe under the truncated cone 7, and an opening or outlet between the cone m
and the truncated conc 1. At the upper part of the door and at the highest part
of the foundation ring are openings or perforations no o, also communicating
with the atmosphere. These openings serve for the exit of the waste products of
combustion of the flame and of the heated air. At preferably the lowest part of
the pyramid is an orifice protected by a wind guard and serving for the
entrance of air to sustain the flame and also to ignite the lamp without opening
the door.
*
The gas is led to the burner through the pipe s secured to the base piece & and
barrel 24, the latter being provided with a suitable plug the whole being suspended
from the supply gas pipe by means of a suspension pipe coupled to the socket w
in the usual manner.
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° The construction of side reflecting lamps with a reflecting surface of conical or
pyramidical form and composed of enamelled metal or glass or other suitable
reflecting material so that the maximum amount of the light provided may be
reflected directly upon the object to be illuminated substantially as described.
2° In side reflecting lamps, ventilating or getting rid of the waste products of
combustion and heated air not passed through the main ventilating pipe by means of
perforations, in the upper part of the lamp and in the door, communicating from the
interior of the lamp to the atmosphere sulistantially as described.
3° In side reflecting lamps, protecting the enamelled glass serving as a reflecting
medium and having the required advertisement painted on the back thereof from
external injury by means of corresponding coverings of clear glass substantially as
described.
4° The arrangement and construction of side reflecting lamps substantially as
described with reference to the drawings.
