PROVISIONAL SPECIFICATION.
Improvements in Shades for Electric Glow Lamps.
I, HENRY WILLIAM TAYLOR of 111, Euston Street, Euston Square, London,
N.W., Brass Finisher, do hereby declare the nature of this invention to be as
follows:-
My invention relates to the manufacture of shades or screens for electric glow
lamps as used in shop windows and elsewhere for the purpose of intercepting and
reflecting the light, and the invention consists essentially in the application of a
new material for this purpose whereby novel effects are produced and in the mode
of manufacture whereby the material in question is brought to the requisite shape
for the purpose.
The new material which I employ is ox-horn which by reason of its semi-
translucency and variegation of color and texture displays when illuminated by
being placed in close proximity to an incandescent glow lamp, an almost endless
variety of natural markings and colorings, which enhance the effect of its partial
translucency.
In adapting this material to the purpose in view, the horn is prepared and cut out
to about the shape of the screen or shade and is then submitted to pressure in metal
moulds heated to a temperature almost sufficient to blister or brown the horn, in
which it is retained under pressure until the horn has acquired the desired form and
has become permanently set, so that when subsequently applied near the lamp it
will not become misshapen by the heat thereof.
The form of the finished screen or shade is concave so as to partially surround
the bulb of the lamp and more or less in the form of a spoon or a shell, the general
configuration and design being however susceptible of almost unlimited variation.
It is formed with a shank or stem rather thicker than the shade itself to which is
screwed or otherwise affixed a metal clamping collar formed preferably of two
curved members hinged to a centre piece and united at their free ends by a
tightening screw, the said collar being adapted to embrace the lamp socket for the
purpose of supporting the screen or shade in position.
Dated this 2nd day of March 1892.

COMPLETE SPECIFICATION.
Improvements in Shades for Electric Glow Lamps.
I, HENRY WILLIAM TAYLOR of 111, Euston Street, Euston Square, London,
N.W. Brass Finisher, 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 relates to the manufacture of shades or screens for electric glow
lamps as used in shop windows and elsewhere for the purpose of intercepting and
reflecting the light, and the invention consists essentially in the application of a new
material for this purpose whereby novel effects are produced, and in the mode of
manufacture whereby the material in question is brought to the requisite shape for
the purpose. The new material which I employ is the horn of animals of the
bovine genus, which, by reason of its semi-translucency and variegation of color and
texture, displays when illuminated by being placed in close proximity to an
D1

page_text: incandescent glow lamp an almost endless variety of natural markings and colorings
which enhance the effect of its partial translucency.
In adapting this material to the purpose in view, the horn is prepared and cut out
to about the intended shape of the screen or shade and is then submitted to
pressure between a pair of metal moulds heated to a temperature almost sufficient
to blister or brown the horn (say about from 110° to 120° F.) in which it is
retained under pressure until the horn has acquired the form of the moulds or dies
and has become permanently set, so that when subsequently applied near the lamp
it will not become misshapen by the heat thereof. The form of the finished screen
or shade is concavo-convex, so as to partially surround the bulb of the lamp, as
illustrated in the accompanying drawing, forming part of this Specification,
Figure 1 of which represents a front elevation, Figure 2 a rear elevation, Figure 3
a cross-sectional elevation, and Figure 4 a horizontal section, on line 1-1, of a shade
or screen resembling in form the bowl of a spoon, but it is to be understood that the
general configuration and design of the screen or shade may be different from that
shewn for instance it may be scalloped at the edges or be otherwise shaped and
embossed so as to resemble a shell or bulb. It is in all cases more or less concave,
but otherwise its form is susceptible of almost unlimited variation.
The screen or shade A is formed with a shank or stem a rather thicker than the
shade itself, which is screwed or otherwise affixed to a metal clamping collar B
formed preferably of two curved members 6162, one of which is hinged at 6 and
united at their free ends by a tightening screw 3, the said collar being adapted to
embrace the lamp socket for the purpose of supporting the screen or shade in
position.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, ] declare that what I
claim is-
The manufacture of the herein described screen or shade for electric glow lamps
of horn pressed up in heated dies or moulds to a concavo-convex form, substantially
as specified.
