PROVISIONAL SPECIFICATION.
An Improved Shade for Oil, Gas, Electric, or other Lights.
We, JAMES FREDERICK HOYNE, of 3 Haigh Terrace, Kingstown, Dublin,
Publisher, and GEORGE ROBERT STODDART, of 6 Dowgate Hill, Cannon Street,
London, Paper Merchant, do hereby declare the nature of this invention to be as
follows
--
This invention relates to an improved form of shade for oil, gas, electric or other
lights, which will have the effect of ventilating the space between such shade and
the chimney, globe or light to which it is applied, whereby the shade will be less
liable to get damaged and perish from heat, while at the same time the construction
of the shade enables certain novel and pleasing effects to be produced, and which
will be hereinafter described.
The shade is composed of two parts placed one over the other and each of
substantially the same form as an ordinary shade, but instead of cach part being
full it is composed of alternate openings and full parts, running in the direction of
the height of the shade, and the outer part being arranged so that the full parts
thereof come above the spaces in the under part. The spaces and full parts are so
proportioned that the full parts of the outer part overlap the edges of the spaces
of the under part. The upper edges of the two parts are secured to a metal or
other ring or gallery, but in such a way that a certain clearance is left between the
under part and the outer part (instead of same lying flat one in contact with the
other), so that air can circulate freely under the full parts of the outer part and
through the spaces of the inner part, and heat can pass outwards from the
space within the shade in the reverse direction, when the shade is in use, whereby
the shade will be kept perfectly ventilated and will thus last longer than ordinary
shades.
The under side of the full parts of the outer part are preferably covered with a
reflecting surface of any suitable colour, so that when the light strikes thereon it
will be thrown down upon the upper surface of the edges of the full parts of the
under part, thus producing a pleasing effect, which may be varied indefinitely
according to the nature or colour of the reflecting surface of the outer part. The
full parts of either the inner or outer part, or both, might further be formed of some
transparent or semi-transparent material, or have any suitable designs cut through
same, such cut away portions being filled in or covered with a transparent
or semi-transparent material, so that the light shining through same will produce
further novel and pleasing effects, which may be also indefinitely varied by
varying the colour of the transparent or semi-transparent material through which
the light shines.
If necessary the lower edges of the two parts constituting the shade may be
strengthened by a ring of metal or other material, which may be either common to
both, or a separate ring may be used for each part.
The shade described is applied to the light with which it is to be used by any
suitable means, such as those at present employed for supporting shades on lamps
or other lights.
The two parts of the shade are preferably formed of cardboard, millboard, or
other similar material, each part being stamped out in one operation with the
alternate spaces and full parts complete, a strip of material at bottom (or if desired
at both bottom and top) connecting the full parts together. The blanks thus
formed are bent to the desired couical form, and their edges secured together by

page_text: clips, or by glueing or otherwise, when they are ready to be placed one over the
other in the position above described, and the top of same (and if desired also
the bottom) secured to the metal ring or gallery which maintains them securely in
such position.

COMPLETE SPECIFICATION.
An Improved Shade for Oil, Gas, Electric, or other Lights.
We, JAMES FREDERICK HOYNE, of 3 Haigh Terrace, Kingstown, Dublin,
Publisher, and GEORGE ROBERT STODDART, of 6 Dowgate Hill, Cannon Street,
London, Paper Merchant, 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 :-
This invention relates to an improved form of shade for oil, gas, electric or other
lights, which will have the effect of ventilating the space between such shado and
the chimney, globe or light to which it is applied, whereby the shade will be less
liable to get damaged and perish from heat, while at the same time the construction
of the shade enables certain novel and pleasing effects to be produced, and which
will be hereinafter described.
In the accompanying drawings:-
:―
Fig. 1 is a half vertical section and half front elevation of a shade constructed
according to our invention in its simplest form, and
Fig. 2 is a plan view thereof.
The shade is composed of two parts A and B, placed one over the other, and
each of substantially the same form as an ordinary shade, but instead of each part
being full, it is composed of alternate openings a and b, and full parts a¹ and b¹,
preferably running in the direction of the height of the shade, and the outer part A
being arranged so that the full parts a¹ thereof come over the spaces 6 of the under
part B. The spaces and full parts are so proportioned that the full parts a¹ of the
outer shade A overlap the edges of the spaces b of the under part B. The upper
edges of the two parts A and B are secured to a metal or other ring or gallery C,
but in such a way that a certain clearance is left between the under part B and
the outer part A (instead of same lying flat one in contact with the other), so that
air can circulate freely under the full parts a¹ of the outer part A, and through
the spaces of the inner part 1, and heat can pass outwards from the space
within the shade in the reverse direction, when the shade is in use, whereby
the shade will be kept perfectly ventilated and will thus last longer than ordinary
shades.
The underside of the full parts a¹ of the outer part A, or the upper side of the
full parts of the under part B, or both, are preferably covered with a reflecting
surface of any suitable colour, so that when the light strikes on the under side of
the full parts a' of the part A, it will be thrown down upon the upper surface of
the edges of the full parts of the under part B, thus producing a pleasing effect,
which may be varied indefinitely according to the nature or colour of the reflecting
Burface or surfaces of the parts A or B, or both. The full parts of either the inner
or outer part, or both, might further be formed of some transparent or semi-
transparent material, or have any suitable designs cut through same, such cut away
portions being filled in or covered with a transparent or semi-transparent
inaterial, so that the light shining through same will produce further novel
and pleasing effects, which may be also indefinitely varied by varying the
colour of the transparent or semi-transparent material through which the light
shines.

page_text: If necessary the lower edges of the two parts A and B, constituting the shade,
may be strengthened by a ring of metal or other material, which may be either
common to both, or a separate ring may be used for each part, or the edges of such
parts A and B may be simply stuck together as shown.
The shade described is applied to the light with which it is to be used by
any suitable means, such as those at present employed for supporting shades on
lamps or other lights, and a convenient form of which is shown in the drawings,.
but which as same presents no material difference from those already in use needs
no description.
The two parts A and B of the shade are preferably formed of cardboard,
millboard, or other similar material, each part being stamped out in one operation
with the alternate spaces and full parts complete, a strip of material at bottom (or
if desired at both bottom and top) connecting the full parts together. The blanks
thus formed are bent to the desired conical form, and their edges secured together
by clips, or by glueing or otherwise, when they are ready to be placed one over the
other in the position above described, and the top of same (and if desired also the
bottom) secured to the metal ring or gallery which maintains them securely in
such position.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
A shade for oil, gas, electric or other lights, composed of two parts which are
superposed, but supported so as to leave a clearance or space between the top and
bottom parts, both of such parts being formed with alternate openings and full parts,
and the openings in one being so situated that they are opposite the full parts of
the other, substantially as and for the purpose specified.
