PROVISIONAL SPECIFICATION...
An Improved Globe or Shade for Gas Lights.
I, WILLIAM FOLEY of 17, Osborne Terrace Clapham Road London, S.W.
Gentleman, do hereby declare the nature of this invention to be as follows:-
My Invention relates to the manufacture of a glass shade for gas.lights formed at
the top after the manner of a corona and entirely closed in at the top where the
ordinary glass gas globes are left open for the escape of hot air.
Immediately underneath the corona shaped top I make all round my improved
shade a number of holes through which the hot air from the gas lights escape and
such air is thus prevented from rebounding upon the flame. of the gas and thus a
genuine and steady light is obtained from the gas consumed.
The sides of my improved shade first slope slightly outwards from the gallery
upon which the globe rests and then recede backwards towards the centre of the
globe at about an angle of 80 degrees torminating at the top with the corona shaped
head as before referred to.

COMPLETE SPECIFICATION.
An Improved Globe or Shade for Gas Lights.
I, WILLIAM FOLEY of 17 Osborne Terrace, Clapham Road, London S. W. Gentleman
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, and illustrated by accompanying drawing
:-
My Invention relates to an improved Globe for Gas Lights and has for its object
to provide a smoke consuming device closed at the top which will produce a steady
and brilliant light.
The essential feature of my invention is the formation of a corona integrally with
the upper part of a globe having by preference outwardly sloping walls such corona
being so devised as to prevent the ascending hot air from rebounding upon the flame,
which has been a serious defect in all former gas globes which were closed at the top.
At the lower part of this corona are formed around the same a series of air holes of oval
or other suitable shape. It is particularly owing to the capacity of the corona that
the air is immediately led out through the said holes without its being able to
rebound upon the flame. My improved gas globe is preferably made of glass but I
may likewise construct the same of opal, opaline, porcelain or other suitable
material.
And in order that my invention may be more fully understood I have shown the
same in the accompanying drawing in which
Fig. 1 is a front view of my improved gas globe. Fig. 2 is a section on line A B
of Fig. 1. Fig. 3 shows the globe fixed upon the gallery of a gas bracket.
S is the shade of the form clearly shown in Fig. 1 and 2. The top of this globe
carries a corona C which is provided at its lower part with a series of air
holes hhh. encircling the same. As previously stated the hot air rising
from the gas flame F is led owing to the peculiar shape of the globe S and of the
corona C directly to the air holes h. h¹. . . . be such air twirling around the inner
walls and at the top of the corona but never rebounding or returning downwardly
upon the flame as it entirely escapes through the said air holes before being able to
proceed any further.

page_text: As my improvements are capable of some slight modification without departing
from the principle thereof do not restrict myself to material, dimensions, or to the
precise form, or number of holes or slots or other shaped holes.
Having now fully described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, 1 declare that what I
claim is
The improved gas globe, formed at the top with a corona furnished with air holes
at its lower or receding part arranged, constructed, and operating substantialy as
described and shewn for the purpose set forth.
