PROVISIONAL SPECIFICATION.
Improvements in the Mode of Fitting and Fixing the Globes, Shades,
and Burners of Gas and Oil Lamps, and other Illuminants.
I, HERBERT DREW of 14 High Street Clapham, in the County of Surrey, Iron-
monger, and Gas Engineer do hereby declare the nature of this invention to be as
follows:--
My invention consists in certain improvements in the construction and arrangement
of the shades or globes in conjunction with, and relation to the burners, chimneys,
reflectors, and supports of gas, atmospheric, oil, and candle lights; whereby their
illuminating power is improved and increased; and the artistic effect is greatly enhanced,
as compared with others in ordinary use.
The arrangement is most suitable for gas lights constructed on the Argand principle;
or for any other, requiring a glass, mica, or other transparent chimney; or for any
:description of oil lamps, when such chimneys are necessary or desirable; or for any
.kind of candles, night lights or similar illuminants, whether enclosed in such
chimneys or otherwise: and my improvement consists, in arranging the shades or globes
surrounding or enclosing such lights; so that the maximum amount of illumination
is concentrated, and thrown in such direction as may be most convenient or
desirable..
To accomplish this, I suspend the shade or globe from above, by attaching to its
upper opening, any suitable globe holder, which in turn is attached to a suitable
bracket or pipe, from which the whole depends; thus minimising the shadow cast
downwards, and leaving the under or bottom opening in said shade or globe, free to
throw the light downwards, or outwards without obstruction.
The shade or globe may be set at any required angle, but the burner and light,
with the chimney enclosing same, may by preference be in a vertical position.
The said chimney may be led up to, or may pass through the upper opening from
which the shade or globe is suspended; or if found necessary or desirable, an additional
opening may be formed on the upper or under side; or on both upper and under sides
of said shade or globe; in a direct line with, and sufficiently large to clear or pass
the top (or bottom and top) of said chimney and fittings. In the case of gas lights, the
gas tube passes by preference through the centre of the upper opening, from which
the shade or globe is suspended; and is conducted downwards to the burner, as close
to the said chimney as may be convenient or desirable. By this arrangement, the
gas becomes heated before being ignited, and its illuminating power is thereby
considerably increased.
In the case of oil lamps or candles being used; the supporting arrangement for
these may be altered or modified to suit the altered conditions, and are not essential
to my invention.

COMPLETE SPECIFICATION.
Improvements in the Mode of Fitting and Fixing the Globes, Shades,
and Burners of Gas and Oil Lamps, and other Illuminants.
I, HERBERT DREW of 14 High Street Clapham in the County of Surrey, Ironmonger,
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 consists in certain improvements in the construction and arrangement
of the shades or globes, in conjunction with, and relative to the burners, chimnevs.

page_text: reflectors and supports of gas, candle, oil and other burners; whereby their illuminating
power is improved, and the artistic effect is greatly enhanced, as compared with others
in ordinary use.
My improved arrangement is most suitable for gas lights constructed on the Argand
principle, or for any other burner requiring a glass or other chimney, or for any
description of oil lamps where such chimneys are necessary or desirable or for any
kind of candles, night lights, or similar illuminants, whether enclosed in such chimneys
or otherwise; and my improvement consists in arranging the shades or globes
surrounding such lights, so that the maximum amount of illumination is concentrated
and thrown in such direction as may be most convenient or desirable.
To accomplish this, I suspend the shade or globe, preferably from above, by attaching
to its inner opening, any suitable globe-holder, which is in turn attached to any
suitable bracket or pipe and from which the burner, with any suspending or supporting
arrangement depends the shade or globe being held at any required angle; but the
burner and light, with any chimney attached to same, being by preference supported
in a vertical position. The chimney may be led up to, or may pass through the inner
.opening from which the globe or shade is suspended or supported; or it may pass up
to or through the outer opening; or it may pass through, or up to a distinct or
additional opening formed on the upper surface of the globe or shade, according as
the shape or configuration of said globe or shade, and the angle to which it is set,
may be found most necessary or desirable.
An opening may also be formed on the under side or surface of any globe or
shade, where the shape or configuration of such globe or shade, or the angle to which
it is set may render such opening necessary or desirable to pass or clear the under
parts of the burner, chimney, tubes, or fittings of any lamp or light.
In the case of gas lights, the suspending or supporting pipe passes by preference
through the inner opening from which the globe or shade is suspended or supported,
and is conducted by preference downwards to the burner, as close to the chimney as
may be desirable.
By this arrangement, the gas passing through said pipe, becomes heated before
being ignited, and its illuminating power is thereby considerably increased.
And in order that my invention may be thoroughly understood, I shall now more
particularly explain the foregoing description of same, by reference to the figures
in the accompanying sheet of drawings, which illustrate my invention as applied at
various angles to gas brackets in combination with "Argand" burners; like letters
of reference indicating corresponding parts in the respective figures.
Figure 1 illustrates my invention as applied to an ordinary Argand burner, with
a Venetian glass shade suspended at a downward angle and the chimney of Argand
burner passing out, through the inner or suspending opening of said shade.
Figure II illustrates my invention as applied to a similar shade and burner; the
shade being supported at an upward angle, and the chimney passing out towards the
top of the outer opening of shade.
Figure III illustrates my invention as applied to a dome shaped globe in com-
bination with an Argand burner the globe being supported in a horizontal position
from its inner opening, and having separate holes at top and bottom to pass or clear
the chimney and fitting of Argand burner.
In these figures A. A. A. represents the globes or shades, B. B. B. represent
the "Argand" burners; C. C. C. represent the chimneys of " Argand" burners:
D. D. D. represent the brackets or pipes for conveying the gas to burner, and
for supporting the globe or shade and burner; E. E. E. represent the globe holders
which are attached to the pipe D: F. F. F. represent the inner opening of
globe or shade; G. G. represent the outer openings of shades; H represents an
opening on top of globe A in Figure III, through or towards which the chimney C
may pass if desired.
J represents an opening on underside of globe A in Figure III
through or towards which the burner B may pass if desired. K. K. K. represent
the suspending or supporting arrangement connecting the bracket or pipe D with the
burner B and conveying gas to the burner if desired.

With reference to these figures, I do not confine my invention to their exict
details, as they merely illustrate the manner in which it is or may be applied to
Argand" burners, in combination with shades or globes set at various angles; but
it may be modified so as to be applied to oil lamps, atmospheric burners gas lights and
candles of every description..
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-
1st. The fixing and setting of the globes or shades of gas and oil lamps, to any
required angle other than perpendicular, when applied in conjunction with burners
requiring glass or other chimneys.
2nd. The fixing or setting of the globes or shades to any required angle as afore-
said, when applied in conjunction with gas lights, oil lamps, candles or night lights
with or without chimneys.
All substantially, and for the purposes herein described, in reference to, and shown
in the accompanying drawings or any mere modification thereof.
In witness whereof, &c.
