Improvements in and relating to Reflectors for Electric Incandescent
Lamps.
.
I, CHARLES DARRAH of Miller Street, Manchester, in the County of
Lancaster, Merchant, do hereby declare the nature of this invention to be as
follows:-
This invention relates to the reflectors for incandescent lamps and its object is to
provide such reflectors with devices or means for advertising, imparting information
or attracting attention, or to render them more ornamental.
In carrying this invention into effect the reflector has perforated cut or otherwise
formed through its substance any desired letter or letters or character or device.
Thus for example, for use in a shop, the proprietor's name may be cut in a reflector,
or each of a series of reflectors may be furnished with one or more letters of his
name. In all cases the perforations are covered by plain, cut, or coloured glass,
talc, mica, or similar material, which may be secured in place by claws clips or
other suitable or similar devices, and which may if desired have engraved or formed
thereon any suitable inscription device or character.

Improvements in and relating to Reflectors for Electric Incandescent
Lamps.
I, CHARLES DARRAH, of Miller Street, Manchester in the County of
Lancaster, 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 reflectors for incandescent lamps and its object is to
provide such reflectors with devices or means for advertising, imparting information,
or attracting attention, or to render them more ornamental.
In carrying this invention into effect, the reflector has perforated, cut, or other-
wise formed or produced through its substance, any desired letter or letters,
character or device in such a manner as to be plainly visible when the lamp is
lighted. Thus, for example, for use in a shop, the proprietor's name may be cut in
a reflector, or each of a series of reflectors may be furnished with one or more
letters of his name. The perforations may be covered by plain or coloured glass,
talc, mica, or similar material, which may be secured in place by claws, clips, or
other similar or suitable devices, and which may, if so desired, have engraved or
formed thereon any suitable device or character.
The accompanying drawings, to which I hereinafter refer, illustrate in what
manner my invention may be carried into effect.
Figures 1 and 2, illustrate a shell shaped reflector constructed to embody these
51 011

page_text: improvements, and shew its application to an incandescent lamp. Figure 1 shews
the reflector in elevation, from the back, and Figure 2, in cross section.
Figures 3 and 4 are views at right angles to each other, of a lamp provided with
a modified form of reflector.
As shewn by Figures 1 and 2, A is an incandescent lamp provided with a shell
shaped reflector B. This reflector may have cut or otherwise formed in its
substance, letters, characters or devices, in such a manner that they are plainly
visible when the lamp is lighted. The openings in the reflector may be glazed or
similarly covered and the glass may bear an inscription or device. In the reflector
shewn, a star shaped opening is formed and is covered by a piece of glass C, preferably
coloured, and bearing the No. 34 by way of example. Any other suitable
characters or inscription may of course be substituted, as for example, the name of
a firm. A convenient way of inscribing the glass is to take a sheet of flashed glass
and produce the desired device inscription or the like through the flashing by the
sand blast or etching. The inscription or the like then appears plain, upon a coloured
ground, when the lamp is in use.
In another form of reflector, the letters or characters may be cut through the
reflector as shewn by Figures 3 and 4. The reflector may be of a form similar to
that previously described, or it may, as shewn, form part of the lamp. In this case,
the lamp A is silvered to any desired extent in the usual well known manner or
suitably, and the letters or other required devices are cut out of the reflecting
material, as, for example, by the sand blast. Alternatively, the characters inscription
or the like may be first made on the bare glass bulb of the lamp in any soluble
material, resin varnish for example, upon which the silver will not deposit,
and which may, if desired, be removed by a suitable solvent after the bulb is
silvered.
The lamps and reflectors hereinbefore described are especially suitable for retail
shop window illumination, where the backs of the reflectors are presented to the
spectators.
Having now 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 :-
Reflectors for incandescent lamps, provided with characters, letters, devices or
the like, substantially as and for the purpose herein before described and as
illustrated by the accompanying drawings.
