PROVISIONAL SPECIFICATION.
Improvements in or connected with Shades, Globes, or Glasses for
Electric or other Lights.
We. JULES ALEXANDRE DUVAL, Gentleman, and ALPHONSE HENRI NELSON, Paper-
hanger, both of No. 15 Rue des Halles, Paris, France, do hereby declare the naturo
of this invention to be as follows :-
:—
This invention has for its object to soften or subdue intense light such as that of
an electric or other lamp whilst at the same time affording additional security in
case of breakage of the shade, bulb, globe or glass surrounding the electric lamp or
other source of the light.
For this purpose the shade, bulb, globe or glass is provided with an envelope or
covering of beads of crystal or of glass, cut in facets or smooth, and of any desired
shape or shapes, size or sizes and color or colors, which beads are strung upon threads
or as we prefer upon metallic wires in such a manner as to constitute an envelope
to enclose or surround the shade, bulb, globe or glass.
The threads or wires are attached to a bottom ring, and constituto meridians on
which the bends are arranged according to size in such a manner that the envelope
shall conform as closely as practicable to the shape of the shade, bulb, globe or
glass.
The threads or wires are attached at their upper ends to two curved arms or parts
hinged or jointed together in such a manner that when these are open the shade,
bulb, globe or glass to be covered can be introduced into the envelope from the top
and side, after which the said arms or parts are closed on to the collar or rim of
the socket surmounting the shade, bulb, globe or glass, the arrangement being
such that in case of breakage of the latter, the broken glass will be retained by the
envelope.
When applied to a globe open at the top, the envelope rests on the same support
as the globe.
By this invention the intensity of the light can be subdued and diffused without
its being necessary to render the shades, bulbs, globes or glasses dull by grinding or
otherwise and, as already stated, additional security is afforded.

COMPLETE SPECIFICATION.
Improvements in or connected with Shades, Globes, or Glasses for
Electric or other Lights.
We, JULES ALEXANDRE DUVAL Gentleman, and ALPHONSE HENRI NELSON, Paper-
hanger, both of No. 15 Rue des Halles, Paris, France, 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 has for its object to soften or subdue intense light, such as that of
an electric or other lamp, whilst at the same time affording additional security in case
of breakage of the shade, buib, globe or glass surrounding the electric lamp or other
source of the light.
For this purpose the shade, globe or glass is provided with an envelope or covering
of beads of crystal or of glass, cut in facets or smooth, and of any desired shape or

page_text: shapes, size or sizes, and color or colors, which beads are strung upon threads, or, as
we prefer, upon metallic wires, in such a manner as to constitute an envelope to
enclose or surround the shade, globe or glass.
Referring to the annexed drawings
Fig. 1 illustrates in elevation the bulb A of an electric incandescent lamp, sealed
underneath the collar or ring D of the socket B which carries the carbon
filament C.
Fig. 2 shews in elevation, the envelope or covering in which the bulb A is to
be placed and which is shewn partly opened.
Fig. 3 is a plan.
Fig. 4 is an elevation of the bulb enclosed in the envelope or covering which has
been closed by being hooked on to the collar or ring D.
By means of lower beads P and a metallic thread or wire a beaded ring is formed
to which may be attached the threads or wires G G, upon which are strung
transparent beads H H, of glass or crystal, that may be white or colored, and be
smooth or cut with facets.
or
These beads which may be of round polygonal, cylindrical or prismatic form, are of
various sizes and dimensions, in order that by means of their graduation, the
envelope or covering shall conform as closely as practicable to the shape of the bulb.
Each of the wires G G is attached at its upper part to two curved arms
paris b,hinged or jointed together at E. When this hinge is open there exists
between its arms and the flexible edges II¹ formed by the first and last beaded
wires, an opening through which the bulb A may be introduced from the top or
from the side, into the envelope or covering, wherein the bulb is enclosed by closing
the hinged arms b, ¹ together.
The arms bb terminate in lugs 0 0₁ which are or can be constructed to engage
with each other in the manner of a spring clasp or fastening, as is the case in some
hinges or clasps of purses and-travelling bags. A screw V may be employed to
further secure the closure or fastening thus obtained.
The arms hook or engage on to or over the circular collar D in such a manner
that in case of the breakage of the bulb, the envelope or covering will not fall and
will retain the broken glass.
In the arrangement shewn in Fig. 5 where the shade bulb, globe, or glass is open
at the top and encloses either a voltaic are according to Jablochkoff's system for
example, or a flame from a burner as shewn, the envelope or covering is made in the
same manner, but it is supported in position on the same support as the globe and is
retained by means of linged arms as shown, the arrangement in this case also being
such as to retain the fragments of glass in the event of the globe, of whatever form
it may be, being broken by falling pieces of carbon or from any other cause.
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:
For a shade, bulb, globe or glass, of an electric or other lamp, a transparent or
translucent envelope or covering constructed of beads H, H strung on wires or
threads G, G, that are attached at one end to a botton ring P, and at the other end
to two arms b, hinged or jointed together the said envelope or covoring being
adapted to close upon the said shade, bulb, globe, or glass A, and to engage with the
collar or ring D for carrying the same or to close upon a globe A', supported from
below and to rest on the support of such globe; the whole as described and
illustrated for the purpose specified.
