PROVISIONAL SPECIFICATION.
A New or Improved Device for Supporting Shades or Reflectors for
Incandescent Electric Lamps.
I, ERNEST DUNAND, of the firm of Louis Dernier and Company, of 78 Newman
Street, London, W., Lamp and Electric Shade Manufacturer, do hereby declare
the nature of this invention to be as follows:-
-:
This invention relates to a new or improved device for supporting shades or
reflectors for incandescent electric lamps, the object being to apply a shade or a
reflector by means of wire clips which whilst being readily applied to clip the
glass bulb of the lamp will be light, strong and will not obstruct the rays to any
extent that would be appreciable.
According to one form of construction, two loops of wire are employed, the
upper ends of such wire loops being brought together two by two and attached
by soldering, looping or looping and soldering to a gallery or ring. This gallery
or ring may be made with a short neck-like prolongation or rim and when so made
may receive directly the shade whether of porcelain, china, glass or of textile
material or of paper. According to a modification the ring supported upon the
spring loops may have attached thereto radiating wires connected by other wires
in opposite direction curved or straight according to pattern and this will support
the shade. The loops of wire are curved downward and outwards in a varying
curve so that the wider part of the loops will accomodate the larger part of the
glass bulb of the lamp and so form spring clips.
At the upper part of the said loops extending out just below the ring support
aforesaid, there is a wire eye of size and so placed as to receive the terminating
point of glass of the bulb so holding all firmly and compactly together when
in use.
Instead of the spring clips supporting the ring, they may be attached to and
support a reflector."

A New or Improved Device for Supporting Shades or Reflectors for
Incandescent Electric Lamps.
I, ERNEST DUNAND, of the firm of Louis Dernier and Company, of 78 Newman
Street, London, W., Lamp and Electric Shade Manufacturer, 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 a new or improved device for supporting shades or
reflectors for incandescent electric lamps, the object being to apply a shade or
reflector by means of wire clips which whilst being readily applied to clip the
glass bulb of the lamp, will be light, strong, and will not obstruct the rays to any
extent that would be appreciable.
According to one form of construction, two loops of wire are employed the
upper ends of which are brought together, two by two, and attached by soldering
or by looping, or by soldering and looping to a gallery or ring. This gallery or
ring may be made with a short neck-like prolongation or rim and when so made

lass or a wire frame
According to the modification, the ring supported upon the spring loops may
have attached thereto radiating wires connected by other wires in opposite direction
curved or straight according to pattern and this will support the shade.
The loops of wire are curved downward and outwards in a varying curve so that
the wider part of the loops will accomodate the larger part of the glass bulb of
the lamp and so forming spring clips. At the upper part of the said loops
extending out below the ring support aforesaid, there is a wire eye of size and so
placed as to receive the terminating point of glass of the bulb so holding all firmly
and compactly together when in use.
Instead of the spring clips supporting the ring they may be attached to and
support a reflector.
In the drawings annexed hereto there is illustrated two variations of this
improved holder device.
Figure 1, is an elevation shewing a front view of the spring clips and gallery
with a lamp shade applied thereto, the latter being shewn in section.
Figure 2, is an elevation shewing a side view of the spring clips and a wire
supporting frame such as may be employed to support a shade of limp material,
textile or paper or the like.
a,
is the incandescent lamp bulb, a' is the terminating point of the glass bulb.
b, are the wire loops formed to a varying curve which at the lower part will clip
the lamp bulb and is formed with a varying curve upward to the point where the
ends of the two opposite clips come together.
In Figure 1, these ends are shewn soldered to the gallery c, but in Figure 2,
they are shewn looped to a wire ring d. This ring d has looped thereto a bent
wire supporting frame e. The gallery c, Figure 1, is shewn with a shade applied
thereupon.
The projecting arın f (extending from the gallery c in the one figure and
extending from the ring d in the other figure) terminates with an eye or loop so
as to extend over, receive and securely hold the terminating point a¹ of the glass
bulb a of the lamp.
Having thus particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim, is;-
1. In a holder device for supporting shades or reflectors for incandescent
electric lamps, the spring clips such as b. ' combined with the gallery c and the
eyed arm, constructed and operating as and for the purpose set forth.
2. In a holder device for supporting shades or reflectors for incandescent electric
lamps, the spring clips such as b. & combined with the ring d, supporting frame e
and the eyed support f, as and for the purpose substantially as specified.
