PROVISIONAL SPECIFICATION left by the said Harry Edward Alexander
Wallis at the Office of the Commissioners of Patents on the 17th August
1883.
HARRY EDWARD ALEXANDER WALLIS, of 86 Farringdon Street in the City of
London, County of Middlesex, Gas Engineer IMPROVEMENTS IN GAS OR LAMP
SHADES, AND IN SUPPORTS FOR SAME
The first part of my invention consists in using sheets of Millboard or Cardboard
composed wholly or in part of Asbestos, rolled and enamelled, or glazed; as an
incombustible Material for the Manufacture of Shades
The second part of my invention consists in supporting the above or any other
Shades, by means of metal plates affixed to the inner or reflecting sides thereof;
with eyelets, rivets, or other suitable fastening.
Each of these plates has a raised square embossed upon it, and the support has a
square washer or nut of metal, so affixed to it, as to allow the end of the support
to pass through a hole in the Centre of the embossed metal plate.
To the end of the support that projects through the Shade, I attach by means
of a screw-thread, a metal nut or cap; so arranged as to bring firmly into the
Square seating on the plate, the metal nut or washer inside of the shade.

HARRY EDWARD ALEXANDER WALLIS of 86 Farringdon Street in the City of
London County of Middlesex Gas Engineer "IMPROVEMENTS IN GAS OR LAMP
SHADES, AND IN SUPPORTS FOR THE SAME
"
The first part of my Invention consists in so preparing sheets of millboard or
cardboard, composed wholly or in part of asbestos, as to produce an enamelled or
glazed surface on one or both sides of the sheets. To carry out the principle of this
invention, one side of these sheets must be finished with a white glaze in order to
act as a good reflecting medium; the other side or surface may be finished white,
green or other suitable tint,-The sheets so prepared I uso as an incombustible
material for the manufacture of Gas or Lamp shades.
The second part of my Invention consists of improvements in supports for the
above or any other shades, in describing which I would refer to the drawings
accompanying and forming part of this Specification; in which similar letters
represent similar parts.
In carrying out these improvements I affix one or more metal plates A on to the
inner or reflecting side of the shade-B,-by-means-of-eyelets, rivets, or-other-suitable
fastening C.-Each of these plates A has a raised square D embossed upon it, and
the support has a square washer E or nut of metal, so affixed to it, as to allow the
end of the support to pass through a hole in the centre of the embossed metal
plate A. To the end of the support that projects through the shade, I attach by
means of a screw thread, a metal nut or cap F, so arranged as to bring firmly into
the square seating D on the plate A, the metal nut or washer E inside of the
shade.
น
By means of this invention a shade usually requiring three or more wires to
support it can be kept firmly in position with only one or two wires, without any
tendency to tilting, owing to the firm grip obtained by means of the plate A,
embossed square D, square washer E, and metal nut F.
Having therefore described the features of my invention I would claim as new.
First: The use of millboard or cardboard composed wholly or in part of asbestos
prepared in the manner setforth and described, as a non-combustible material for
the manufacture of, gas, lamp, and candle shades.
Secondly: The method and arrangements, and combination of parts A. B. C. D,
E and F, for supporting the above, or any other gas, lamp, or candle shades,
substantially as setforth and described.
In Witness whereof I the said Harry Edward Alexander Wallis have hereunto
set my hand and seal this twenty eighth day of February in the year of our Lord
One thousand eight hundred and eighty four.
