MENTS IN LAMPS."
"IMPROVE-
My Invention relates to improvements in the construction of Lamps, and
particularly to Lamps for lighting streets, landing stages, and other large open
spaces. In carrying out my invention, I construct a Lamp of any suitable shape,
and with any desired number of sides (such as six for example) The top or
roof of the lamp I prefer to glaze with opal glass, but the sides are glazed with
panes of clear glass each having in the centre of the outside (or thereabouts) a
large glass lens, which I prefer to attach to the surface of the pane of glass by
means of "Coaguline" or similar transparent cement-with or without the addition
of screws, metallic strips, or other means, and so as to produce the least shadow.
I fix one or more burners at the back of each of the lenses, inside the lamp,
provided with a suitable reflector to concentrate the light upon the lens.
I use an Argand, batswing, or other suitable burner that will give a brilliant
light, and by this arrangement of flat panes of glass and lenses, in combination
with reflectors, a portion of light is diffused around through the flat panes of glass,
at the same time a powerful concentrated light is projected forwards through the
lenses.

by the said Henry Cullabine in the Great Seal Patent Office on the
. 8th February 1883.
HENRY CULLABINE of Sheffield in the County of York, Gasfitter, "IMPROVE-
MENTS IN LAMPS "
My Invention relates to improvements in the construction of Lamps, and
particularly to lamps for lighting streets, large open spaces, landing stages, and
such like, with any medium such as gas, electricity, or oil, and it consists chiefly
in the arrangement and method of fixing lenses, with or without reflectors as
hereinafter more particularly described.
In carrying out my invention I construct the body of the Lamp of any suitable
shape, and with any desired number of sides such as six for example. The top
or roof of the Lamp, I prefer to glaze with opal glass, and the sides with clear glass.
In one arrangement of my invention, I attach a lens to the outer surface of each
of the side panes of glass, preferably by means of coaguline or similar transparent
cement, the side of the lens placed against the glass being flat, and as additional
means of security, small bolts may be used at the edge of the lens in such a
manner as to produce the smallest amount of shadow. Inside the Lamp and
opposite each lens I fix a concave or other shaped reflector, and between the two,
a suitable burner of any construction that will give a brilliant light; by this
arrangement a portion of the light is diffused through the flat panes, and a
powerful concentrated light is projected through the lenses.
In a second arrangement of my invention, which is illustrated in the sheet of
drawings annexed, to which I will now refer, Figure 1 being an elevation of a
lamp arranged for the use of gas, and Figure 2 being some of the details of same
enlarged, I use a body A of any suitable shape, but preferably with four, six or
eight flat sides B and in the interior I arrange a corresponding number of projecting
arms G (or as many as may be required) connected to a central upright E. At
the end of each projecting arm I attach a lens C, shown distinctly in Fig 2,
arranged so as to project the light at the desired angle; behind the lens C, is fixed
the burner F, and a reflector D, may be secured permanently, or may be made to
slide on the arm.
In some cases, such as when a lamp is required to light on every side, the
reflectors may be dispensed with. It will be obvious that the details of the lamp
would require altering when the electric light is used.
By this arrangement of lenses and reflectors in lamps, a combination of diffused,
soft light, with a strong, concentrated, projected light is obtained, such combination
being very useful for lighting up Docks, Landing Stages, Barrack grounds, and
other large areas, as well as the interior of large buildings.
Having thus particularly described the nature of my invention, and the manner
of putting the same into use, I would observe in conclusion that what I consider
to be novel and original and therefore claim as the invention secured to me by the
herein before in-part recited Letters Patent, is :-
"
First, In Lamps for lighting large spaces, by electricity, gas, or other medium;
the use of lenses attached to the outside of the panes of glass, by means of transparent
cement, such as Coaguline "-
- or by small bolts at the edges of the lens, suitable
reflectors being placed at the back of the burners substantially in the manner
herein before described.

page_text: Second. In Lamps as before described, the arrangement of lenses in the interior,
with or without reflectors, for the purpose and in the manner, substantially as
herein before described and illustrated.
In Witness whereof I, the said Henry Cullabine have hereunto set my
hand and seal, the sixth day of February in the year of our Lord, One
thousand Eight hundred and Eighty three.
