IMPROVEMENTS IN LAMPS OR LANTERNS
Year: 1885

page_text: I CORNELIUS CRASTIN of 185 Hornsey Road in the county of Middlesex,
Gas Engineer and Lamp Manufacturer do hereby declare the nature of my said
invention for "IMPROVEMENTS IN LAMPS OR LANTERNS" to be as follows
1
This invention relates to improvements in the construction of lamps or lanterns
used for lighting shop fronts and for street and like lamps or lanterns, the improve-
ments having chiefly for object to increase the strength and cheapen the manufacture
of such lamps or lanterns and in the case of shop front lamps to dispense with the
portable hanging arms usually employed and to employ flat flamed burners in place
of the usual argand burners and chimneys
In carrying out my invention as applied to reflecting lanterns for lighting shop
fronts and like purposes, I construct the top ring by casting it from suitable metal
and with projecting arms or ribs to which I attach the top bars of the frame of the
lantern, the said ring forms a strong support for the reflector and hurricane top
and provides the main support for bearing the lamp, the remainder of the frame is
formed of the usual bars but I provide corner pieces of suitable metal to which the
ends of the bars are rivetted and the whole frame is then by preference dipped into
a suitable molten alloy such as a compound of two parts tin and one of lead by
which means the joints are well secured and the frame preserved from deterioration
from the effects of exposure to the atmosphere
The sides and back of the lamp are glazed or provided internally with fluted
silvered glass, opal glass, burnished copper or other suitable reflectors, the reflecting
cone being arranged at an angle so as to allow the lamp to be placed at a greater
height than hitherto at the same time that the rays of light will be directed in the
required direction and without the reflection of the lamp appearing in the line of
sight The sides and back of the lamp on the outside are adapted to receive
advertisement tablets which can be changed as required
The air for the combustion 18 supplied from the top of the lamp and flat flamed
burners are employed in place of the usual argand burners thereby dispensing withi
glass chimneys
In street and like lamps the top and frame of the lamp are constructed as
herein before described but the base of the lantern is formed of a metal casting
with suitable projections or corner pieces to which are connected the lower ends of
the side bars of the fiame whereby the lantern can be fixed direct to the lamp
column or post thereby dispensing with the usual cradle now employed

I CORNELIUS CRASTIN, of 185 Hornsey Road, in the county of Middlesex,
Gas Engineer and Lamp Manufacturer 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
1
This invention relates to improvements in the construction of lamps or lanterns
used for lighting shop fronts and for street and like lamps or lanterns, the improve-
ments having chiefly for object to increase the strength and cheapen the manufacture
of such lamps or lanterns and in the case of shop front lamps to dispense with the
portable hanging arms usually employed and to employ flat flamed burners in place
of the usual argand burners and chimneys
In carrying out my invention as applied to reflecting lanterns for lighting shop
fronts and like purposes I construct the top ring by casting it from suitable metal
and with projecting arms or ribs to which I attach the top bars of the frame of the
lantern, the said ring forms a strong support for the reflector and hurricane top
and provides the main support for bearing the lamp, the remainder of the frame is
formed of the usual bars but I provide corner pieces of suitable metal to which the
ends of the bars are rivetted and the whole frame is then by preference dipped into
a suitable molten alloy such as a compound of two parts tin and one of lead by
which means the joints are well secured and the frame preserved from deterioration
from the effects of exposure to the atmosphere
The sudes and back of the lamp are glazed or provided internally with fluted
silvered glass, opal glass, burnished copper or other suitable reflectors, the reflecting
surfaces of the lamp being arranged at an angle so as to allow the lamp to be placed
at a greater height than hitherto at the same time that the rays of light will be
directed in the required direction and without the reflection of the lamp appearing
in the line of sight The sides and back of the lamp on the outside are adapted to
receive advertisement tablets which can be changed as required
The air for the combustion is supplied from the top of the lamp and flat flamed
burners are employed in place of the usual argand burners thereby dispensing with
glass chimneys.
In street and like lamps the top and frame of the lamp are constructed as
hereinbefore described but the base of the lantern is formed of a metal casting
with suitable projections or corner pieces to which are connected the lower ends of
the side bais of the frame whereby the lantern can be fixed direct to the lamp
column or post thereby dispensing with the usual cradle now employed
In order to enable my invention to be fully understood I will proceed to describe
the same by reference to the accompanying drawing in which figure 1, 18 a central
transverse section of a reflecting lamp or lantern constructed according to my
invention and suitable for lighting shop fronts and like purposes, figure 2, 18
a horizontal section of the same on line A, B of figure 1, figure 3 is a vertical
section on line C, D of figure 2, figure 4 is a detached plan view drawn to
a larger scale of the top ring shewing the method of attaching the frame of the

page_text: lamp thereto, figure 5 is a section on line E, F, of figure 4, figure 6 is a detached
view of one of the corner pieces. Similar letters in all the figures represent similar
parts.
a represents my top ring formed by casting from suitable metal and b, b, are the
projecting arms or ribs of the same, c, c, are the top bars of the frame of the
lantern which are attached to the arms or ribs b, b, by means of rivets d, as shewn
in figures 4 and 5, the bars c, are formed trough shaped and with flanges the
troughs serving to receive the arms or ribs b, through which and through the sides
of the troughs the rivets d, are passed as shewn and the flanges serving to support
the edges of the sheets of glasse of the top of the lantern as shewn in figure 2 in
which the flanges are shewn in dotted lines at a¹, f, is the reflector which is fixed
to the ring a by screws g (or otherwise), h, is the hurricane top which is supported
by a flange or ring, on the top of the lantern which flange or ring is attached to
the top bars o,
the top ring a, is fixed to the gas supply pipe 7, by means of arms k,
connected to the ring a by the screws g, and to the pipe 3, by a screw thread Z,
thereon, m 18 & nut on the pipe 3, below the top of the arms k, serving to securely
support the lantern, it will thus be seen that the ring a, provides the main support
for bearing the lamp, m¹, figure 5 shews one of the corner pieces to which the
usual bars forming the remainder of the frame of the lantern are rivetted and the
frame is as herein before described dipped in a suitable molten alloy for the purpose
of securing the joints and preserving the frame, n, n, are the sides and o, is the
door or back of the lamp glazed or provided internally with suitable reflectors,
the outer sides being adapted to receive advertisement tablets as herein before
described, p, p, are the burners of the lamp which are flat flamed instead of the
usual argand burners, thereby dispensing with the necessity of employing glass
chimneys, b¹, 18 the glass forming the bottom of the lantern and c¹ the glass front
of the same
The exterior air for supporting the combustion enters as shewn by the arrows in
figure 3, through the hurricane top h, and as it is drawn into the interior of the
lamp passes over the outer surface of the reflecting cone f, thereby becoming heated
in its passage to the burners p, p, the heated air and products of combustion then
pass up through the reflecting cone f, and out through the opening q, in the
hurricane top h
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
The combination of parts forming the improved lamp or lantern substantially as
herein before described and represented in the accompanying drawing
