Electric Lamps and for Electric Arc Lamps, and for Facilitating
the Application of Advertisements thereto.
I, ERNEST BÖHM, of 5, Boxworth Grove, Richmond Road, Barnsbury, N., Glass
Manufacturer and Electrician, do hereby declare the nature of this invention
to be as follows:-
This invention relates to certain new or improved combined globes and shades
for incandescent electric lamps, and for electric are lamps and for facilitating
the application of advertisements thereto.
I will now describe the invention so as to ascertain at once the objects sought
to be effected and how the same may be carried into practical effect:-
"
The globe or bulb of the lamp will be made with a body portion and above
the said body portion an enlarged portion somewhat flattened out so as to formı
what may be termed a "bonnet" extending outward beyond and overhanging to
that extent, the bulb or globe within which the filiament or carbons are located
and from which the emission of light proceeds or is derived.
In this manner, the globe and the shade will be formed of a piece by the
process of "blowing-glass" or as may be found applicable.
As for convenience of description the term "bonnet" has been made use of to
illustrate this construction of lamp globes and shades, the word "brim" will
also be employed to denote the underside of the said shade which extends out from
and beyond the globe portion of the combined article around and above the same.
For incandescent electric lamps the globe will be fitted with electric connections
with the filaments attached and the socket piece for the application to the socket
brim will extend out (in
holder, in ordinary manner above the globè the
substantially horizontal direction) and from the outer edge of said "brim" the
bonnet will be arched over as a
and be closed in substantially ordinary
manner by "blowing." The setting up of the vacuum within the combined
globe and shade will be effected in well known manner.

crown
وو
The electric filament connections and socket may of course be applied above
the globe and shade (centrally of the crowne of the "bonnet") as will be well
understood, and according to convenience and purposes for which the lamps will
be designed or applied.
For the application of this combined globe, brim and shade for electric arc
lamps an opening or openings will be provided above, or above and below to
allow of the application of the electric, lamp and fittings.
The application of advertisements made in any desired manner to the "brim"
of combined globes and shades such as herein described will be claimed as
essential of this invention and it is to be remarked that the emission of light
will be below the said "brim".and the application of advertisements or announce-
ments as applied to such brim will not obscure the emission of light, as is the..

page_text: case where such advertisements are applied upon electric lamps or bulbs, but if
such be used, the surface of the brim affords additional available area
therefor, and the power of the reflection will not be detrimentally affected.
"3
The " crown of the shades may be treated to form reflectors by silvering,
gilding enamelling, or by making the bonnet or crown of colored glass, or of
opal or frosted glass blown in with the brim" and globe.
"
The bulb of the incandescent lamp may be of crystal glass or be colored or
frosted as desired but making changed effect with the brim of the bonnet, or the
silvered gilded opal or other reflector crown.
The combined globe and shade will provide a very effective and economical
appliance for shop window decorations and illumination and similar purposes
and avoiding expense of metal, crystal and other shades which are costly additions
and require considerable attention.
For electrical advertisement signs, wherein numerous incandessent lamps are
used to outline a letter or letters words or signs the brim of such lamps and
the reflector crown will highly enhance the effect.
The scope of the decorative application and design in such lamps may be
considered almost unlimited. The advertisement or decorative signs on the brim
may be burnt in, enamelled or otherwise applied.
New or Improved Combined Globes and Shades for Incandescent
Electric Lamps and for Electric Arc Lamps, and for Facilitating
the Application of Advertisements thereto.
I, ERNEST BÖHм, of 5, Boxworth Grove, Richmond Road, Barnsbury, N., Glass
Manufacturer and Electrician, 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 the manufacture, in one operation, of a globe and
shade for electric incandescent and arc lamps, the shade of such lamps being
made of such a shape as to facilitate the application of advertisements thereto.
In the accompanying drawing I have shown the invention as applied to an
incandescent lamp,
Fig 1 being a side elevation, and
Fig. 2 an inverted plan view of the same.
"
A is the globe, into which dips the carbon filament which is to be illumined
by an electric current. Above the globe A is the shade B, which forms a
"bonnet" of larger diameter than the globe. This leaves a surface or "brim,"
which is presented to view from below, and is made to receive any motto or
device having the character of an advertisement, as indicated in the figures.
The shade or bonnet" will be provided at top with a reflecting medium of
silver or its equivalent, which may be burnt in or otherwise applied, and the
globe and shade, being formed from blown glass, the light evolved from the
incandescent filament will illumine the shade internally, and bring clearly into
view the letters, figures, or device applied to the underside or brim of the
bonnet." This "brim," it will be seen, is made with a curved face, the better

page_text: to display any device that may be applied to it, when the lamp is viewed from a
plane slightly below the elevation of the lamp. As the fixed position of these
lamps may vary with respect to the line of sight of the spectator, the shape
of the bonnet" rim, to adapt it for displaying, in the best manner, the device
which is applied thereto, may also be varied with advantage.
"
Fig. 3 shews in side view, and
Fig. 4 in inverted plan, a lamp slightly modified in form, which gives a flat
"brim" instead of the rounded one shewn at Fig. 1. In other respects, the
lamps are similar. They are provided with a socket piece C of the usual kind
for suspending the lamp and bringing it within the electric circuit.
For the application of this invention to arc lamps, an opening must be
provided above the shade or bonnet, or above the shade and below the globe, to
allow of the application of the electric lamp thereto.
From the foregoing description it will be understood that the emission of
light will be both below and through the brim," and the advertisement or
device upon the said brim will be brought prominently into view, without
obstructing the emission of light from the lamp.
The crown of the shades may, in place of being converted into reflectors,
as above explained, be made of crown or colored glass, or of opal, or frosted
glass, burnt on or otherwise applied at the time of forming the "brim" and globe.
The bulb of the incandescent lamp may be of crystal glass, or be colored or
frosted, as desired, to harmonize or contrast with the shade or bonnet."
"
It will be understood that the combined globe and shade will provide a very
effective and economical appliance for shop window decorations, illuminations,
and similar purposes, while at the same time avoiding expense of metal, crystal,
and other shades, which are costly additions, and require considerable attention.
For electrical advertisement signs, wherein numerous incandescent lamps are
used to outline a letter or letters, words, or signs, the brim of such lamps, with
a reflector crown to the bonnet, will highly enhance the effect.
The advertisement or decorative signs on the brim may be burnt in, enamelled,
or otherwise applied.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed. I declare that what
I claim is:-
The manufacture, from blown glass, of combined globes and shades for electric
incandescent and arc lamps, as and for the purpose above set forth.
